401(k)

In the United States, a 401(k) plan is an employer-sponsored, defined-contribution, personal pension (savings) account, as defined in subsection 401(k) of the U.S. Internal Revenue Code. Periodic employee contributions come directly out of their paychecks, and may be matched by the employer. This pre-tax option is what makes 401(k) plans attractive to employees, and many employers offer this option to their (full-time) workers. 401(k) payable is a general ledger account that contains the amount of 401(k) plan pension payments that an employer has an obligation to remit to a pension plan administrator. This account is classified as a payroll liability, since the amount owed should be paid within one year.

There are two types: traditional and Roth 401(k). For Roth accounts, contributions and withdrawals have no impact on income tax. For traditional accounts, contributions may be deducted from taxable income and withdrawals are added to taxable income. There are limits to contributions, rules governing withdrawals and possible penalties.

The benefit (vs. a normally taxed account) of the Roth account is from permanently tax-free profits that would normally be taxed in a normal account. The net benefit of the traditional account is the sum of (1) the same benefit as from the Roth account from the permanently tax-free profits on after-tax saving, (2) a possible bonus (or penalty) from withdrawals at tax rates lower (or higher) than at contribution, and (3) the impact on qualification for other income-tested programs from contributions and withdrawals reducing and adding to taxable income.

As of 2019, 401(k) plans had US$6.4 trillion in assets.

History

Before 1974, some U.S. employers had been giving their staff the option of receiving cash in lieu of an employer-paid contribution to their tax-qualified retirement plan accounts. The U.S. Congress banned new plans of this type in 1974, pending further study. After that study was completed, Congress reauthorized such plans, provided they satisfied certain special requirements. Congress did this by enacting Internal Revenue Code Section 401(k) as part of the Revenue Act. This occurred on November 6, 1978.

The first implementation of the 401(k) plan was in 1978, about three weeks after Section 401(k) was enacted, before the Revenue Act of 1978 even went into effect. Ethan Lipsig, of the outside law firm for Hughes Aircraft Company, sent a letter to Hughes Aircraft outlining how it could convert its after-tax savings plan into a 401(k) plan.

Ted Benna was among the first to establish a 401(k) plan, creating it at his own employer, the Johnson Companies (today doing business as Johnson Kendall & Johnson). Benna was trying to reduce the taxes due on an deferred-compensation bonus plan for bank executives, at a time when the top marginal income tax rate was 70%. Employees could contribute 25% of their salaries, up to $30,000 per year, to their employer's 401(k) plan.

Taxation

There are two main types corresponding to the same distinction in an Individual Retirement Account (IRA); variously referred to as traditional vs. Roth, or tax-deferred vs. tax exempt, or EET vs. TEE.

Traditional

The tax-saving benefits from Traditional accounts (as measured by the difference in outcomes vs a normally taxed account) are the sum of two benefit-factors. 1) A possible benefit (or cost) is from the eventual withdrawal multiplied by the difference in tax rates between contribution and withdrawal. The hope is that the retirement rate will be lower, for a benefit. Effective tax rates are used to incorporate the impact of contributions and draws on the saver's qualification for benefits from other income-tested programs.

2) Everyone always receives the same benefit as from a Roth account - the benefit from permanently tax-free profits on after-tax savings. The conceptual understanding is that the contribution's tax reduction is the government investing its money alongside the saver's, for him to invest as he likes. They become co-owners of the account. The government's share of the account (funding plus the tax-free profits earned by it) at withdrawal fully funds the account's withdrawal tax calculated at the contribution's tax rate. So the contribution's tax reduction is never a benefit, and profits are never taxed. The withdrawal tax is conceptually an allocation of principal between owners, not a 'tax', and there is no benefit 'from deferral'.

For pre-tax contributions, the employee still pays the total 7.65% payroll taxes (social security and medicare). If the employee made after-tax contributions to the 401(k) account, these amounts are commingled with the pre-tax funds and simply add to the 401(k) basis. When distributions are made, the taxable portion of the distribution will be calculated as the ratio of the after-tax contributions to the total 401(k) basis. The remainder of the distribution is tax-free and not included in gross income for the year.

Roth

Main article: Roth 401(k)

Beginning in the 2006 tax year, employees have been allowed to designate contributions as a Roth 401(k) deferral. Similar to the provisions of a Roth IRA, these contributions are made on an after-tax basis.

For accumulated after-tax contributions and earnings in a designated Roth account (Roth 401(k)), "qualified distributions" can be made tax-free. To qualify, distributions must be made more than 5 years after the first designated Roth contributions and not before the year in which the account owner turns age 59+1⁄2, unless an exception applies as detailed in IRS code section 72(t). In the case of designated Roth contributions, the contributions being made on an after-tax basis means that the taxable income in the year of contribution is not decreased as it is with pre-tax contributions. Roth contributions are irrevocable and cannot be converted to pre-tax contributions at a later date. (In contrast to Roth individual retirement accounts (IRAs), where Roth contributions may be recharacterized as pre-tax contributions.) Administratively, Roth contributions must be made to a separate account, and records must be kept that distinguish the amount of contribution and the corresponding earnings that are to receive Roth treatment.

Unlike the Roth IRA, there is no upper-income limit capping eligibility for Roth 401(k) contributions. Individuals who find themselves disqualified from a Roth IRA may contribute to their Roth 401(k). Individuals who qualify for both can contribute the maximum statutory amounts into either or a combination of the two plans (including both catch-up contributions if applicable). Aggregate statutory annual limits set by the IRS will apply.

Withdrawal of funds

Generally, a 401(k) participant may begin to withdraw money from his or her plan after reaching the age of 59+1⁄2 without penalty. The Internal Revenue Code imposes severe restrictions on withdrawals of tax-deferred or Roth contributions while a person remains in service with the company and is under the age of 59+1⁄2. Any withdrawal that is permitted before the age of 59+1⁄2 is subject to an excise tax equal to ten percent of the amount distributed (on top of the ordinary income tax that has to be paid), including withdrawals to pay expenses due to a hardship, except to the extent the distribution does not exceed the amount allowable as a deduction under Internal Revenue Code section 213 to the employee for amounts paid during the taxable year for medical care (determined without regard to whether the employee itemizes deductions for such taxable year). Amounts withdrawn are subject to ordinary income taxes to the participant.

The Internal Revenue Code generally defines a hardship as any of the following.

• Unreimbursed medical expenses for the participant, the participant's spouse, or the participant's dependent.
• Purchase of principal residence for the participant.
• Payment of college tuition and related educational costs such as room and board for the next 12 months for the participant, the participant's spouse or dependents, or children who are no longer dependents.
• Payments necessary to prevent foreclosure or eviction from the participant's principal residence.
• Funeral and burial expenses.
• Repairs to damage of participant's principal residence.

Some employers may disallow one, several, or all of the previous hardship causes. To maintain the tax advantage for income deferred into a 401(k), the law stipulates the restriction that unless an exception applies, money must be kept in the plan or an equivalent tax deferred plan until the employee reaches 59+1⁄2 years of age. Money that is withdrawn prior to the age of 59+1⁄2 typically incurs a 10% penalty tax unless a further exception applies. This penalty is on top of the "ordinary income" tax that has to be paid on such a withdrawal. The exceptions to the 10% penalty include: the employee's death, the employee's total and permanent disability, separation from service in or after the year the employee reached age 55, substantially equal periodic payments under section 72(t), a qualified domestic relations order, and for deductible medical expenses (exceeding the 7.5% floor). This does not apply to the similar 457 plan.

As a response to the COVID-19 pandemic, the CARES Act allowed people to withdraw funds before the age of 59+1⁄2 up to $100,000 without the 10% penalty due for 2020.

Loans

Many plans also allow participants to take loans from their 401(k). The "interest" on the loan is paid not to the financial institution, but is instead paid into the 401(k) plan itself, essentially becoming additional after-tax contributions to the 401(k). The movement of the principal portion of the loan is tax-neutral as long as it is properly paid back. However, the interest portion of the loan repayments are made with after-tax funds but do not increase the after-tax basis in the 401(k). Therefore, upon distribution/conversion of those funds, the owner will have to pay taxes on (only) the interest funds a second time.

The loan principal is not taxable income nor subject to the 10% penalty as long as it is paid back in accordance with section 72(p) of the Internal Revenue Code. This section requires, among other things, that the loan is for a term no longer than 5 years (except for the purchase of a primary residence), that a "reasonable" rate of interest be charged, and that substantially equal payments (with payments made at least every calendar quarter) be made over the life of the loan. Employers, of course, have the option to make their plan's loan provisions more restrictive. When an employee does not make payments in accordance with the plan or IRS regulations, the outstanding loan balance will be declared in "default". A defaulted loan, and possibly accrued interest on the loan balance, becomes a taxable distribution to the employee in the year of default with all the same tax penalties and implications of a withdrawal.

Required minimum distributions (RMD)

Main article: Required minimum distribution

Account owners must begin making distributions from their accounts by April 1 of the calendar year after turning age 70+1⁄2 (72 for individuals who turn age 70+1⁄2 after December 31, 2019) or April 1 of the calendar year after retiring, whichever is later. The amount of distributions is based on life expectancy according to the relevant factors from the appropriate IRS tables.

The required minimum distribution is not required for a particular calendar year if the account owner is employed by the employer during the entire calendar year and the account owner does not own more than 5% of the employer's business at any point during the calendar year. Required minimum distributions apply to both traditional contributions and Roth contributions to a 401(k) plan.

A person who is required to make a required minimum distribution, but does not do so, is subject to a penalty of 50% of the amount that should have been distributed.

In response to the United States economic crisis of 2007–2009, Congress suspended the RMD requirement for 2009. It was suspended again in 2020 due to the COVID-19 pandemic.

Required distributions for some former employees

A 401(k) plan may have a provision in its plan documents to close the account of former employees who have low account balances. Almost 90% of 401(k) plans have such a provision. As of March 2005, a 401(k) plan may require the closing of a former employee's account if and only if the former employee's account has less than $1,000 of vested assets.

When a former employee's account is closed, the former employee can either roll over the funds to an individual retirement account, roll over the funds to another 401(k) plan, or receive a cash distribution, less required income taxes and possibly a penalty for a cash withdrawal before the age of 59+1⁄2.

Rollovers

Rollovers between eligible retirement plans are accomplished in one of two ways: by a distribution to the participant and a subsequent rollover to another plan or by a direct rollover from plan to plan. Rollovers after a distribution to the participant must generally be accomplished within 60 days of the distribution. If the 60-day limit is not met, the rollover will be disallowed and the distribution will be taxed as ordinary income and the 10% penalty will apply, if applicable. The same rules and restrictions apply to rollovers from plans to IRAs.

Direct rollovers

A direct rollover from an eligible retirement plan to another eligible retirement plan is not taxable, regardless of the age of the participant.

Traditional to Roth conversions

In 2013, the IRS began allowing conversions of existing Traditional 401(k) contributions to Roth 401(k). In order to do so, an employee's company plan must offer both a Traditional and Roth option and explicitly permit such a conversion.

There is a maximum limit on the total yearly employee pre-tax or Roth salary deferral into the plan. This limit, known as the "402(g) limit", was $19,000 for 2019, $19,500 for 2020–2021, $20,500 for 2022, $22,500 for 2023, and $23,000 for 2024. For future years, the limit may be indexed for inflation, increasing in increments of $500. Employees who are at least 50 years old at any time during the year are now allowed additional pre-tax "catch up" contributions of up to $6,000 for 2015–2019, and $6,500 for 2020–2021. The limit for future "catch up" contributions may also be adjusted for inflation in increments of $500. In eligible plans, employees can elect to contribute on a pre-tax basis or as a Roth 401(k) contribution, or a combination of the two, but the total of those two contributions amounts must not exceed the contribution limit in a single calendar year. This limit does not apply to post-tax non-Roth elections.

If the employee contributes more than the maximum pre-tax/Roth limit to 401(k) accounts in a given year, the excess, as well as the deemed earnings for those contributions, must be withdrawn or corrected by April 15 of the following year. This violation most commonly occurs when a person switches employers mid-year and the latest employer does not know to enforce the contribution limits on behalf of their employee. If this violation is noticed too late, the employee will not only be required to pay tax on the excess contribution amount the year was earned, the tax will effectively be doubled as the late corrective distribution is required to be reported again as income along with the earnings on such excess in the year the late correction is made.

Plans which are set up under section 401(k) can also have employer contributions that cannot exceed other regulatory limits. Employer matching contributions can be made on behalf of designated Roth contributions, but the employer match must be made on a pre-tax basis.

Some plans also have a profit-sharing provision where employers make additional contributions to the account and may or may not require matching contributions by the employee. These additional contributions may or may not require a matching employee contribution to earn them. As with the matching funds, these contributions are also made on a pre-tax basis.

There is also a maximum 401(k) contribution limit that applies to all employee and employer 401(k) contributions in a calendar year. This limit is the section 415 limit, which is the lesser of 100% of the employee's total pre-tax compensation or $56,000 for 2019, or $57,000 in 2020. For employees over 50, the catch-up contribution limit is also added to the section 415 limit.

Governmental employers in the United States (that is, federal, state, county, and city governments) are currently barred from offering 401(k) retirement plans unless the retirement plan was established before May 1986. Governmental organizations may set up a section 457(b) retirement plan instead. IRS Raises 2022 401(k) Contribution Limit to $20,500, a $1,000 boost from 2021 contribution limits.

Contribution deadline

For a corporation, or LLC taxed as a corporation, contributions must be made by the end of a calendar year. For a sole proprietorship, partnership, or an LLC taxed as a sole proprietorship, the deadline for depositing contributions is generally the personal tax filing deadline (April 15, or September 15 if an extension was filed).

Highly compensated employees (HCE)

To help ensure that companies extend their 401(k) plans to low-paid employees, an IRS rule limits the maximum deferral by the company's highly compensated employees (HCEs) based on the average deferral by the company's non-highly compensated employees (NHCEs). If the less compensated employees save more for retirement, then the HCEs are allowed to save more for retirement. This provision is enforced via "non-discrimination testing". Non-discrimination testing takes the deferral rates of HCEs and compares them to NHCEs. In 2008, an HCE was defined as an employee with compensation greater than $100,000 in 2007, or as an employee that owned more than 5% of the business at any time during the year or the preceding year. In addition to the $100,000 limit for determining HCEs, employers can elect to limit the top-paid group of employees to the top 20% of employees ranked by compensation. That is, for plans with the first day of the plan-year in the 2007 calendar year, HCEs are employees who earned more than $100,000 in gross compensation (also known as 'Medicare wages') in the prior year. For example, most testing done in 2009 was for the 2008 plan-year, which compared 2007 plan-year gross compensation to the $100,000 threshold in order to determine who was an HCE and who was an NHCE. The threshold was $125,000 for 2019, and is $130,000 for 2020.

The actual deferral percentage (ADP) of all HCEs as a group cannot exceed 2 percentage points greater than all NHCEs as a group. This is known as the ADP test. When a plan fails the ADP test, it essentially has two options to come into compliance. A return of excess can be given to the HCEs to lower the HCE ADP to a passing level, or it can process a "qualified non-elective contribution" (QNEC) to some or all of the NHCEs in order to raise the NHCE ADP to a passing level. A return of excess requires the plan to send a taxable distribution to the HCEs (or reclassify regular contributions as catch-up contributions subject to the annual catch-up limit for those HCEs over 50) by March 15 of the year following the failed test. A QNEC must be vested immediately.

The annual contribution percentage (ACP) test is similarly performed but also includes employer matching and employee after-tax contributions. ACPs do not use the simple 2% threshold, and include other provisions which can allow the plan to "shift" excess passing rates from the ADP over to the ACP. A failed ACP test is likewise addressed through return of excess, or a QNEC or qualified match (QMAC).

There are a number of "safe harbor" provisions that can allow a company to be exempted from the ADP test. This includes making a "safe harbor" employer contribution to employees' accounts. Safe harbor contributions can take the form of a match (generally totaling 4% of pay) or a non-elective profit sharing (totaling 3% of pay). Safe harbor 401(k) contributions must be 100% vested at all times with immediate eligibility for employees. There are other administrative requirements within the safe harbor, such as requiring the employer to notify all eligible employees of the opportunity to participate in the plan, and restricting the employer from suspending participants for any reason other than due to a hardship withdrawal.

Automatic enrollment

Employers are allowed to automatically enroll their employees in 401(k) plans, requiring employees to actively opt out if they do not want to participate (traditionally, 401(k)s required employees to opt in). Companies offering such automatic 401(k)s must choose a default investment fund and saving rate. Employees who are enrolled automatically will become investors in the default fund at the default rate, although they may select different funds and rates if they choose, or even opt out completely.

Automatic 401(k)s are designed to encourage high participation rates among employees. Therefore, employers can attempt to enroll non-participants as often as once per year, requiring those non-participants to opt out each time if they do not want to participate. Employers can also choose to escalate participants' default contribution rate, encouraging them to save more.

The Pension Protection Act of 2006 made automatic enrollment a safer option for employers. Prior to the Pension Protection Act, employers were held responsible for investment losses as a result of such automatic enrollments. The Pension Protection Act established a safe harbor for employers in the form of a "Qualified Default Investment Alternative", an investment plan that, if chosen by the employer as the default plan for automatically enrolled participants, relieves the employer of financial liability. Under Department of Labor regulations, three main types of investments qualify as QDIAs: lifecycle funds, balanced funds, and managed accounts. QDIAs provide sponsors with fiduciary relief similar to the relief that applies when participants affirmatively elect their investments.

Fees

401(k) plans charge fees for administrative services, record-keeping services, investment management services, and sometimes outside consulting services. They can be charged to the employer, the plan participants or to the plan itself and the fees can be allocated on a per participant basis, per plan, or as a percentage of the plan's assets. For 2011, the average total administrative and management fees on a 401(k) plan was 0.78 percent or approximately $250 per participant. However small businesses can suffer especially higher plan fees. The United States Supreme Court ruled, in 2015, that plan administrators could be sued for excessive plan fees and expenses, in Tibble v. Edison International. In the Tibble case, the Supreme Court took strong issue with a large company placing plan investments in "retail" mutual fund shares as opposed to "institutional" class shares.

Top-heavy provisions

The IRS monitors defined contribution plans such as 401(k)s to determine if they are top-heavy, or weighted too heavily in providing benefits to key employees. If the plans are too top-heavy, the company must remedy this by allocating funds to the other employees' (known as non-key employees) benefit plans.

Plans for certain small businesses or sole proprietorships

Main article: Solo 401(k)

The Economic Growth and Tax Relief Reconciliation Act of 2001 (EGTRRA) made 401(k) plans more beneficial to the self-employed. The two key changes enacted related to the allowable "Employer" deductible contribution, and the "Individual" IRC-415 contribution limit.

Prior to EGTRRA, the maximum tax-deductible contribution to a 401(k) plan was 15% of eligible pay (reduced by the amount of salary deferrals). Without EGTRRA, an incorporated business person taking $100,000 in salary would have been limited in Y2004 to a maximum contribution of $15,000. EGTRRA raised the deductible limit to 25% of eligible pay without reduction for salary deferrals. Therefore, that same businessperson in Y2008 can make an "elective deferral" of $15,500 plus a profit sharing contribution of $25,000 (i.e. 25%), and—if this person is over age 50—make a catch-up contribution of $5,000 for a total of $45,500. For those eligible to make "catch-up" contribution, and with salary of $122,000 or higher, the maximum possible total contribution in 2008 would be $51,000. To take advantage of these higher contributions, many vendors now offer Solo 401(k) plans or Individual(k) plans, which can be administered as a Self-Directed 401(k), permitting investment in real estate, mortgage notes, tax liens, private companies, and virtually any other investment.

Note: an unincorporated business person is subject to slightly different calculation. The government mandates calculation of profit sharing contribution as 25% of net self-employment (Schedule C) income. Thus on $100,000 of self-employment income, the contribution would be 20% of the gross self-employment income, 25% of the net after the contribution of $20,000.

Rollovers as business start-ups (ROBS)

ROBS is an arrangement in which prospective business owners use their 401(k) retirement funds to pay for new business start-up costs. ROBS is an acronym from the United States Internal Revenue Service for the IRS ROBS Rollovers as Business Start-Ups Compliance Project.

ROBS plans, while not considered an abusive tax avoidance transaction, are questionable because they may solely benefit one individual – the individual who rolls over his or her existing retirement 401(k) withdrawal funds to the ROBS plan in a tax-free transaction. The ROBS plan then uses the rollover assets to purchase the stock of the new business. A C corporation must be set up in order to roll the 401(k) withdrawal.

Other countries

Even though the term "401(k)" is a reference to a specific provision of the U.S. Internal Revenue Code section 401, it has become so well known that it has been used elsewhere as a generic term to describe analogous legislation. For example, in October 2001, Japan adopted legislation allowing the creation of "Japan-version 401(k)" accounts even though no provision of the relevant Japanese codes is in fact called "section 401(k)".

Similar pension schemes exist in other nations as well. The term is not used in the UK, where analogous pension arrangements are known as personal pension schemes. In Australia, they are known as superannuation funds. In Canada RRSPs (Registered Retirement Savings Plan) play a similar role although they don't have to be employer sponsored and have different contribution limits.

Similarly, India has a scheme called National Pension System (NPS), mandatory for all Central Government employees from January 2004, which is similar to 401(k) in terms of investment options, restriction on withdrawals and tax exemption on contribution, return earned and also withdrawals at retirement age(generally 60). It is also adopted by most state governments for their employees and also opened for the corporate sector. It's regulated by PFRDA Pension Fund Regulatory and Development Authority Some old pension schemes like EPF for private or public sector employees and PPF for self-employed, practicing professionals, small business owners, exist but they offer a lower rate of return that is fixed by Government every quarter.The Employees' Provident Fund Organisation (EPFO) is a statutory body of the Government of India under the Ministry of Labour and Employment. It administers a compulsory contributory Provident Fund Scheme, Pension Scheme, and an Insurance Scheme. The schemes cover both Indian and international workers (for countries with which bilateral agreements have been signed; 14 such social security agreements are active). It is one of the largest social security organisations in India in terms of the number of covered beneficiaries and the volume of financial transactions undertaken. The EPFO's apex decision-making body is the Central Board of Trustees.

Nepal and Sri Lanka have similar employees provident fund schemes. In Malaysia, The Employees Provident Fund (EPF) was established in 1951 upon the Employees Provident Fund Ordinance 1951. The EPF is intended to help employees from the private sector save a fraction of their salary in a lifetime banking scheme, to be used primarily as a retirement fund but also in the event that the employee is temporarily or no longer fit to work. As of March 31, 2014, the size of the EPF asset size stood at RM597 billion (US$184 billion), making it the fourth-largest pension fund in Asia and seventh-largest in the world.

Criticisms and proposed reforms

Risk of loss

Unlike defined-benefit pensions (regulated by ERISA) or an FDIC-insured savings account at a bank, there is no government guarantee for assets held in 401(k) accounts.

Investments in stocks can lose value due to market fluctuations. Diversification can protect against poor performance in any one stock or industry, but not against a widespread decline like the Great Depression or Great Recession. Further diversification into bonds can protect against stock market declines, but generally have smaller earning potential and still carry the risk of bondholder default. Earners are generally advised to shift from higher-risk, higher-return assets to lower-risk assets as they near retirement age.

Money can also be lost if the plan sponsor has financial difficulties, though if a sponsor goes bankrupt, 401(k) account holders have high priority. Earners can take sponsor risk into account when deciding whether to leave assets in the plan sponsored by a former employer or roll over the assets to a new employer plan or to an individual retirement account (IRA).

Fees charged by 401(k) providers can substantially reduce earnings.

Choosing investments

401(k) plans are restricted to investments chosen by employers. This can prevent earners from risky choices like picking individual stocks, but also from following a favored investment strategy or asset types (such as commodities), or choosing socially responsible investing. IRA providers typically offer a far wider selection of investments.

Conversely, 401(k) plans are sometimes criticized for putting the burden of choosing and updating investments on earners, most of whom are not experts in finance. Some earners avoid signing up for 401(k)s because of the perceived complexity. Target date funds mitigate this complexity by automatically shifting investments from stocks to bonds based on time to planned retirement date.

Inequality

The tax breaks given for money invested in 401(k)s are only available to people who earn enough money to be able to save for retirement, and does nothing to help the lowest-income earners. This exacerbates existing income inequality, especially if these larger retirement savings are used for the benefit of children (for example to pay for a better education, or simply as inheritance).

Participation

Offering 401(k)s is not mandatory, so not all employers do so; this means some workers simply cannot benefit from the tax breaks. Benefits consultant Ted Benna, who first realized the favorable treatment this section of the tax code afforded defined-contribution plans, has proposed mandating that employers over a certain size offer 401(k)s.

In 2024, one group of researchers advocated ending the tax break for the 401(k) on the grounds that it did not increase aggregate retirement savings, and using the $200 billion in additional tax revenue to support the government-funded Social Security program.

Insufficiency of retirement savings

The amount of money available in retirement from defined-contribution plans like 401(k)s varies considerably depending on the amount contributed and performance of investments. Reliance on these plans instead of defined-benefit pensions and the small fraction of earnings replaced by government programs like Social Security means many people have an insufficient amount of money for retirement. According to US Census data, in 2017, 49% of Americans aged 55 to 66 had "no personal retirement savings". This gap can force people to choose between continuing to work into old age (if they are healthy enough to do so) and living in poverty.

One bipartisan proposal to address this problem is to open the defined-benefit Thrift Savings Plan to all employees (currently it is only for federal government employees).
