The congressional retirement pension is not a separate perk; members of Congress retire through the same Federal Employees Retirement System (FERS) that covers about two million other federal civilian workers. That package has three parts: a defined-benefit pension annuity, Social Security, and a Thrift Savings Plan investment account. What a member ultimately collects depends on years of service, age at separation, salary history, and what they chose to contribute along the way.
Which Retirement System Covers a Member
Two systems exist, and the dividing line is when a member entered federal service. Anyone who started before 1984 was originally under the Civil Service Retirement System (CSRS), a standalone pension that did not include Social Security. The Social Security Amendments of 1983 pulled all sitting members and future federal hires into Social Security and paved the way for FERS, which took effect in 1987.
Members who entered Congress after 1983 are automatically in FERS. A small number of long-tenured members may still be under CSRS or a hybrid CSRS Offset arrangement, but that group is now vanishingly small. Contribution rates, formulas, and eligibility differ between the two, so which system applies matters.
Who Qualifies for a Congressional Pension
The vesting rule is simple. A member must complete at least five years of federal service to get any pension at all. A member who leaves before hitting five years gets a refund of their own contributions and nothing more.
Once vested, when a member can actually start collecting under FERS depends on the combination of age and service:
- Age 62 with 5 years of service qualifies for an immediate, unreduced annuity.
- Age 50 with 20 years of service qualifies, provided the member did not leave by resignation or expulsion.
- Any age with 25 years of service qualifies, again subject to the same resignation-or-expulsion exclusion.
That resignation exclusion catches people off guard. Losing a reelection bid or reaching the end of a term counts as being separated from service, so the member qualifies. Resigning mid-term does not, and a member in that position has to wait until age 62 before drawing an annuity. The rule sits in the statute.1Office of the Law Revision Counsel. 5 USC 8412 – Immediate Retirement
The Minimum Retirement Age Option
FERS includes a fallback for members who reach their Minimum Retirement Age (MRA) with at least 10 years of service but don’t meet the thresholds above. The MRA runs from 55 to 57 depending on birth year: 55 for those born before 1948, 56 for those born between 1953 and 1964, and 57 for anyone born in 1970 or later.2U.S. Office of Personnel Management. Eligibility
The trade-off is steep. Take the annuity right away and it is permanently reduced by 5% for every year under age 62. A member who retires at 57 with 10 years locks in a 25% cut that never goes away, even after turning 62. Postponing payments closer to 62 shrinks or eliminates the penalty, but during the postponement period the member also loses eligibility for the FERS annuity supplement.
How the Pension Amount Is Calculated
The formula starts with the “high-3 average salary”: the average of the member’s three consecutive highest-paid years. Since congressional pay rarely goes down, that is usually the final three years in office. With the rank-and-file base salary frozen at $174,000 as of 2026 and no adjustment approved for the year, most members’ high-3 sits at $174,000.3U.S. Office of Personnel Management. Computation
The formula then applies a multiplier to each year of service. Members of Congress get 1.7% of the high-3 for each year of congressional service up to 20 years, and 1% for each year after that. The 1.7% rate requires at least five years of congressional or congressional-employee service.4Office of the Law Revision Counsel. 5 USC 8415 – Computation of Basic Annuity
Put in numbers: a member who serves exactly 20 years with a high-3 of $174,000 gets 1.7% × $174,000 × 20 = $59,160 per year. A member who serves 30 years gets that $59,160 for the first 20 years plus 1% × $174,000 × 10 = $17,400 for the next decade, for a total of $76,560 annually.
The 80% Cap
CSRS carries a hard statutory ceiling limiting any pension to 80% of a member’s final pay or high-3 average, whichever produces the higher limit.5Office of the Law Revision Counsel. 5 USC 8339 – Computation of Annuity FERS has no explicit cap in its statute, and the math makes reaching 80% essentially impossible: even at the 1.7% rate, a member would need well over 60 years of service to get close.
What Members Pay Into the System
Congressional pensions are not free. Members contribute a percentage of every paycheck toward their retirement annuity on top of the 6.2% Social Security tax. The rate depends on when the member first entered FERS: those who entered federal service after 2012 contribute 3.1% of basic pay, and those who entered after 2013 contribute 4.4%.6Federal Register. Retirement: Members of Congress and Congressional Employees Those rates run higher than what regular federal employees hired in the same years pay, which reflects the enhanced 1.7% accrual.
The Thrift Savings Plan
The second leg of FERS is the Thrift Savings Plan, a 401(k)-style account. In 2026, the maximum elective deferral is $24,500. Members 50 and older can add $8,000 in catch-up contributions, and those turning 60 through 63 in 2026 can add up to $11,250 extra under a SECURE Act 2.0 provision.7The Thrift Savings Plan. 2026 TSP Contribution Limits
The government contributes regardless of what the member does. Every FERS participant gets an automatic 1% of basic pay. On top of that, the government matches employee contributions dollar-for-dollar on the first 3% of pay and 50 cents on the dollar for the next 2%. A member who puts in at least 5% of salary captures the full match, adding 4% from the government on top of the 1% automatic contribution.8Thrift Savings Plan. Contribution Types
TSP balances rise or fall with the funds chosen and market performance. Unlike the pension annuity, the account belongs to the member and carries ordinary investment risk.
Social Security
Before 1984, members of Congress paid no Social Security taxes and drew no Social Security benefits. The Social Security Amendments of 1983 ended the exemption effective January 1, 1984.9Social Security Administration. Social Security Amendments of 1983 Every member now pays the 6.2% employee tax on earnings up to the annual wage base and collects benefits based on full earnings history, like any other worker.10Social Security Administration. Contribution and Benefit Base
A member who retires before 62 with an immediate FERS annuity may also collect a temporary “annuity supplement” that approximates the Social Security benefit they’ll get at 62. The supplement stops when the retiree reaches 62 or becomes eligible for Social Security, whichever comes first.
Cost-of-Living Adjustments
A FERS pension does not automatically hold its value from day one. Most FERS retirees do not receive cost-of-living adjustments until age 62, so a member who retires at 50 with 20 years of service can watch inflation eat into the pension for up to a dozen years before COLAs begin.11U.S. Office of Personnel Management. Cost of Living Adjustments
Even after COLAs kick in, FERS adjustments trail those under Social Security and CSRS. The formula uses a sliding scale tied to the Consumer Price Index. A CPI increase of 2% or less produces a full match. A CPI increase between 2% and 3% is capped at 2%. A CPI increase above 3% gets the CPI minus one percentage point. So a year of 4% CPI gives a FERS retiree 3%, while a CSRS retiree or Social Security recipient gets the full 4%.12U.S. Office of Personnel Management. Chapter 2: Cost of Living Adjustments
When a Member Can Lose the Pension
A congressional pension can be forfeited entirely on a criminal conviction. Two provisions do the work. The Hiss Act strips the full federal retirement annuity from any government employee or official convicted of espionage, treason, or similar national security offenses. A separate provision added by the Honest Leadership and Open Government Act of 2007 and expanded by the STOCK Act in 2012 targets corruption: a member convicted of bribery, fraud, election crimes, or other misconduct committed while in office loses all creditable service earned as a Member of Congress for pension purposes. Other federal service credits may survive, but the congressional years are zeroed out.
The forfeiture applies only when every element of the offense directly relates to the member’s official duties. A conviction for something unrelated to the member’s role in Congress does not trigger it, which is why some convicted former members have kept their pensions and others have lost them.
Survivor Benefits and Insurance After Retirement
If a member dies in office with at least 18 months of creditable civilian service, the surviving spouse may receive a lump sum equal to 50% of the member’s final salary (or high-3 average, if higher) plus a fixed amount that adjusts each year. For deaths after December 2025, that fixed amount is $43,800.53.13U.S. Office of Personnel Management. Survivors
If the deceased had at least 10 years of creditable service, the surviving spouse may also draw ongoing monthly payments. The marriage generally must have lasted at least nine months before death, with exceptions for accidental death or a child of the marriage. Former spouses can qualify if a valid court order is on file with OPM.
For members who die after retirement, the survivor benefit depends on what they chose at retirement. A FERS retiree can elect a survivor annuity of up to 50% of the unreduced pension; a CSRS retiree can elect up to 55%. Either election reduces the retiree’s own monthly payments during life, so the choice is essentially an insurance trade-off made at the point of retirement.14U.S. Office of Personnel Management. Survivor Benefits
Former members can carry Federal Employees Health Benefits (FEHB) coverage into retirement if they qualify for an immediate annuity and were enrolled in an FEHB plan for the five years before retirement, or for their entire service period if shorter.15Congress.gov. Health Benefits for Members of Congress and Designated Congressional Staff Retired members pay the same premiums as other retired federal employees, with the government covering its usual share. Federal Employees’ Group Life Insurance can also continue into retirement under similar five-year enrollment rules, and annuity payments must begin within 30 days of leaving office.16U.S. Office of Personnel Management.
