The Complete Guide to
Federal Retirement
Federal retirement is not one decision. It is a coordinated system of pension income, TSP withdrawals, FEHB, Medicare, Social Security, taxes, and timing.
OPM explains the rules. This guide helps you understand how the rules fit together before retirement decisions become harder to reverse.
How Your Federal Benefits Work Together
How FERS pension, TSP, FEHB, Medicare, Social Security, taxes, and retirement timing fit together.
Your federal benefits provide a foundation for retirement. The decisions are how much income they can support, when to retire and how your choices affect you and your spouse. This guide explains the major FERS rules and how those choices connect.
This overview focuses on FERS. CSRS, special category employees and postal employees may have different rules. Confirm your benefits with your agency benefits office and current government sources.

Common Federal Retirement Questions
Federal employees often arrive here trying to answer questions such as:
The Three Parts of FERS and the Protection Layer
FERS combines the Basic Benefit Plan, Social Security and the Thrift Savings Plan. FEGLI is a separate group life insurance program that may help protect a household alongside these retirement benefits. Source: OPM FERS Information
Hypothetical example: An employee retiring before age 62 under the standard FERS formula, with a $160,000 high 3 average basic salary and 30 years of creditable service, would have a basic annuity of $48,000 per year, or $4,000 per month, before survivor reductions, taxes and insurance deductions. The pension is generally partly taxable and establishes an income base. The household must then decide how much additional income to draw from the TSP and when to claim Social Security. Those choices affect both spending capacity and taxable income.
When Can You Retire Under FERS?
Common voluntary FERS retirement paths depend on age and creditable service. The table summarizes standard immediate retirement paths; special category, early and disability retirement provisions differ. Source: OPM Types of Retirement
| Age at retirement | Creditable service | Age reduction |
|---|---|---|
| 62 or older | 5 years | No age reduction |
| 60 or older | 20 years | No age reduction |
| Minimum Retirement Age (MRA) | 30 years | No age reduction |
| MRA + 10 | At least 10 years, fewer than 30 | Generally 5% for each year before 62; postponing the annuity may reduce or eliminate it |
MRA ranges from 55 to 57 by birth year. It is 57 for people born in 1970 or later. Under MRA + 10, the age reduction is eliminated if you have at least 20 years of service and the annuity begins at 60 or later. Postponing an annuity can create an income and insurance coverage gap; postponed and deferred retirement have different rules. Confirm creditable service, including the required civilian service, with your agency.
The earliest available date is not automatically the right date. A retirement date affects pension income, the FERS Supplement, FEHB continuation, survivor elections, TSP access, and the amount of income that must be produced from other sources.
When Can I Retire Under FERS? →How the FERS Pension Is Calculated
For many standard FERS retirements, the annual basic annuity is high 3 average basic pay multiplied by creditable service and a multiplier. High 3 is the highest average basic pay during any three consecutive years of service, rather than simply the three highest earning years. The standard multiplier is 1%. It is generally 1.1% when an employee separates for retirement at age 62 or later with at least 20 years of service. Special category and disability calculations differ. Source: OPM Computation
The pension becomes the base layer of retirement income. That base layer affects how much income must come from the TSP, whether Social Security should be claimed earlier or later, and how much taxable income is already present before discretionary withdrawals begin.
The FERS Supplement
The FERS Supplement may be payable to certain FERS retirees before age 62. It is intended to approximate the Social Security benefit earned during federal civilian service. OPM states that the supplement ends at age 62 and may be reduced or stopped if earnings from wages or self employment exceed the annual exempt amount. Source: OPM Annuity Supplement
Hypothetical example: An eligible employee retiring at 57 receives a $1,500 monthly FERS Supplement. When the supplement ends at 62, the household must replace $18,000 of annual income if spending stays the same. Claiming Social Security at 62 is one possibility, but its amount must be compared with the supplement and the effect of claiming early. Other possibilities include TSP withdrawals, taxable savings or continued work. The supplement does not require you to claim Social Security at 62.
The FERS Supplement →TSP Withdrawals Change the Retirement Conversation
During the working years, the TSP is usually viewed as an accumulation account. In retirement, it becomes a potential income source. That shift changes the question from how the account grows to how withdrawals are sequenced, taxed, and coordinated with the rest of the retirement system.
Traditional TSP withdrawals are generally taxable as ordinary income, while qualified Roth TSP withdrawals are tax free. Taxable withdrawals can affect tax brackets, Social Security taxation and Medicare IRMAA. Withdrawal eligibility, possible early distribution penalties and Roth qualification rules should be checked before taking money out. Source: IRS Civil Service Retirement Tax Guide
Hypothetical example: A retiree at 63 has a $600,000 traditional TSP balance and takes a $30,000 taxable withdrawal. The withdrawal adds to pension and other income and may cross an IRMAA threshold for Medicare premiums at 65. The result depends on filing status, total modified adjusted gross income and the thresholds for that premium year. Later, once RMDs begin, mandatory distributions may reduce control over taxable income. A withdrawal should therefore be evaluated alongside spending needs, future distributions and healthcare premiums. Source: SSA Medicare Premiums
TSP Withdrawals →Life Insurance and Survivor Protection
FEGLI is the Federal Employees' Group Life Insurance program. During employment, the government generally pays one third of Basic insurance costs; employees pay the full cost of Optional insurance. Coverage and premiums in retirement depend on the coverage held, eligibility and reduction elections. Private insurance may be appropriate when the household has a protection gap, but it is not automatically needed. Source: OPM FEGLI Costs
Continuing FEGLI into retirement generally requires eligible retirement and coverage for the five years of service immediately before retirement, or all opportunities to be insured if shorter. Retirees generally cannot add or increase FEGLI coverage. Cancelling coverage near retirement may jeopardize continuation eligibility. Changes in health can also make private insurance more expensive or unavailable. Review the specific coverage options before cancelling or replacing a policy. Source: OPM Life Insurance in Retirement
Evaluate FEGLI and any private coverage against the survivor's income needs, pension election, debts, assets and healthcare coverage. The goal is appropriate protection at a sustainable cost, with the consequences of each election understood before retirement.
Life Insurance & Survivor Protection →FEHB and Medicare Need to Be Coordinated Before Retirement
Continuing FEHB generally requires an immediate annuity and continuous enrollment or coverage as a family member for the five years of service immediately before retirement, or since the first opportunity to enroll if shorter. Eligible MRA + 10 retirees who postpone the annuity may resume coverage when the annuity starts. OPM has limited waiver authority; do not assume a waiver will be granted. Source: OPM FEHB for Annuitants
Medicare introduces another layer. Retirees covered by FEHB generally do not have to enroll in Medicare Part B to keep FEHB. The decision affects premiums, out of pocket costs and coordination of benefits. Postal retirees covered by PSHB have different Medicare requirements and exceptions; this FEHB discussion should not be applied to them without checking those rules.
Healthcare and income decisions happen at different times. Medicare IRMAA generally uses tax information from two years earlier, so taxable withdrawals or a Roth conversion at 63 may affect premiums at 65. A single income spike does not automatically cause several years of surcharges. SSA may also make a new determination after a qualifying event, such as retirement that lowers income. A surviving spouse's FEHB continuation generally depends on both coverage and entitlement to a survivor annuity. These rules should be reviewed together. Source: SSA Medicare Premiums
FEHB and Medicare →Federal Retirement Taxes Are Often a Sequencing Problem
Federal retirement income may include a taxable pension, taxable traditional TSP withdrawals, Social Security benefits that may be partially taxable, taxable brokerage income, and possible Roth conversions. The order and timing of these income sources can shape lifetime tax burden.
The early retirement years may offer planning flexibility before Required Minimum Distributions begin and before all income sources are fully stacked. Once RMDs, pension income, Social Security, and other income sources overlap, tax flexibility may narrow.
RMDs from a traditional TSP begin at the applicable age under current law, based on birth year. The required amount depends on the prior year end balance and the applicable IRS distribution factor. Withdrawals already taken during the year generally count toward that year's RMD; the RMD is a minimum, not an additional withdrawal automatically stacked on top of every voluntary distribution. Qualified Roth withdrawals and Roth conversions have different tax consequences. Compare the cost of paying taxes now with the potential effect on future income, taxes and Medicare premiums.

Survivor and Legacy Decisions Need Attention Before Retirement
OPM identifies survivor benefit options for FERS retirees, including a full survivor annuity option and a partial survivor annuity option, with corresponding reductions to the retiree's annuity. The election can affect income for a surviving spouse and may also interact with FEHB continuation. Source: OPM Survivors
A survivor election should be evaluated alongside household income needs, FEHB continuation, life insurance, Social Security survivor benefits and estate planning. Declining a survivor annuity can leave an income gap and may affect a spouse's ability to continue FEHB. The outcome depends on the spouse's own income, assets, coverage and eligibility, rather than a single assumed Social Security amount.
Changes after retirement are tightly restricted. OPM allows requests to reduce or cancel a survivor election within 30 days of the first regular monthly annuity payment, with required spouse consent. Certain elections to add or increase a current spouse survivor annuity may be made within 18 months of the annuity commencing date and may involve additional costs. These limited windows are a reason to evaluate the election carefully before retirement. Source: OPM Survivor Benefits
Common Federal Retirement Mistakes
Often times mistakes are not caused by misunderstanding one rule. They are caused by making decisions one at a time without seeing how the full retirement system behaves.
The Wealthspan Perspective
The rules tell you what each federal retirement benefit does. The planning challenge is seeing what those benefits do to each other once retirement begins.
Your retirement date, pension calculation, FERS Supplement, TSP withdrawals, FEHB, Medicare, Social Security, taxes, and survivor choices do not remain separate. They become one retirement system.
Frequently Asked Questions
These questions reflect what federal employees most commonly ask before retirement decisions begin locking into place.
FERS generally includes the Basic Benefit Plan, Social Security and the Thrift Savings Plan. The pension provides a monthly annuity, subject to the retirement path chosen. The TSP is a retirement account with withdrawal and tax rules. Social Security retirement benefits can generally start at 62 or later. Coordinate when income begins, how withdrawals are taxed and how each choice affects household spending and survivor protection.
Common standard immediate retirement paths include age 62 with 5 years of service, age 60 with 20 years, and Minimum Retirement Age with 30 years. MRA + 10 generally involves an age reduction of 5% per year before 62. Postponing the annuity may reduce or eliminate that reduction; with at least 20 years of service, starting at 60 or later eliminates it. Special category and other retirement paths have different rules. Verify eligibility and insurance consequences with your agency benefits office.
For many standard FERS retirements, the annual basic annuity is high 3 average basic pay multiplied by years of creditable service and a multiplier. High 3 means the highest average basic pay during any three consecutive years of service. The standard multiplier is 1%; it is generally 1.1% for employees separating for retirement at 62 or later with at least 20 years of service. Survivor elections and other deductions affect the amount received. Special category and disability calculations differ.
FEGLI is the federal group life insurance program. During employment, the government generally pays one third of Basic insurance costs, while employees pay the full cost of Optional insurance. Continuing coverage into retirement requires meeting eligibility rules; future coverage and costs depend on reduction elections. Additional private insurance may be appropriate if survivor income, debts or other obligations create a protection gap. It is not automatically necessary. Compare existing coverage, assets, pension survivor benefits, costs and insurability.
To continue FEHB into retirement, an employee generally needs an immediate annuity and continuous enrollment or family member coverage for the five years of service immediately before retirement, or since the first opportunity to enroll if shorter. Postponed MRA + 10 retirement has specific reinstatement rules. OPM has limited authority to waive the enrollment requirement, but a waiver should not be assumed. Confirm your coverage history and retirement path before separating.
Traditional TSP withdrawals are generally taxable as ordinary income. They may affect tax brackets, Social Security taxation, Medicare IRMAA and future withdrawal planning. Qualified Roth TSP withdrawals are tax free and generally do not increase income used for those calculations. Eligibility, early distribution penalties and Roth qualification rules also matter. Evaluate the account type, timing and amount alongside household spending and other income sources.
Coordination risk is the risk that retirement decisions are made separately without seeing how they affect each other. A federal employee might maximize TSP contributions to save on taxes during working years, then discover in retirement that a large pre-tax TSP balance forces high mandatory withdrawals that trigger Medicare surcharges and push more Social Security into taxable income. A retiree might delay Social Security to maximize lifetime benefits without modeling whether the household TSP can sustain the withdrawal gap. A retiree might make survivor benefit elections to maximize current income without evaluating what a surviving spouse would have if the retiree dies early. These decisions were each reasonable in isolation, but made without coordination, they create problems that are difficult to fix after the fact.
One of the biggest mistakes is treating each federal benefit as a separate decision. Retirement timing, pension income, FERS Supplement, TSP withdrawals, FEHB enrollment, Medicare enrollment, Social Security timing, tax planning, survivor benefit elections, and healthcare decisions all begin affecting one another once retirement income starts. Decisions made one at a time, in response to deadlines or paperwork, without a view of how they connect across the full system, tend to create coordination gaps that become visible only after they are difficult to address. The most consequential planning often happens in the years before retirement, when the most options are still available and the fewest decisions have been locked in.

Social Security Is Not a Standalone Decision
For many federal retirees, Social Security is layered on top of pension income and TSP withdrawals. Claiming early may reduce lifetime monthly income but lower the amount needed from other assets. Delaying may increase the future benefit but requires another source of income during the bridge years.
Social Security timing also affects survivor income and can interact with taxes through provisional income calculations. The right decision is rarely based only on the benefit estimate. It has to be evaluated within the full income structure.
Hypothetical comparison: One retiree receives a $4,000 monthly pension and has a $500,000 TSP balance; another receives $2,000 and has $300,000 in the TSP. If the first retiree's pension covers essential spending, delaying Social Security may require fewer portfolio withdrawals. If the second retiree has the same spending needs, delaying may require larger withdrawals. Neither outcome can be judged from account balances alone. Compare actual benefit estimates, spending, health, survivor needs and portfolio risk before choosing a claiming age.
