FERS Supplement and Working After Retirement: Which Income Counts and Which Doesn't

Most Post-Retirement Income Doesn't Touch the Supplement

Federal retirees planning second careers, consulting work, or part-time employment often assume the FERS supplement earnings test will claw back their bridge payment the moment they start earning. The reality is more nuanced — and more favorable — than they expect.

The earnings test applies only to active earned income: W-2 wages and net self-employment earnings. Everything else — TSP withdrawals, rental income, investment returns, dividends, capital gains, your FERS annuity — is completely exempt. Many retirees earn substantial post-retirement income without triggering a single dollar of supplement reduction because the income comes from exempt sources.

The Complete Income Classification

Income that counts toward the $24,480 limit (2026):

• W-2 wages from any employer (including part-time, seasonal, or contract-to-hire)
• Overtime and bonuses
• Commissions
• Net self-employment earnings (Schedule C or SE income, after deducting business expenses)
• Severance pay received after your retirement date
• Deferred compensation earned before retirement but paid afterward
• Gross salary from federal reemployment (before dual-compensation offsets)

Income that is completely exempt:

• FERS basic annuity
• The FERS supplement itself
• TSP withdrawals — partial, installment, full, or RMD (traditional and Roth)
• IRA distributions (traditional and Roth)
• Private pensions and military retired pay
• Rental income from investment properties
• Interest income
• Dividend income (qualified and ordinary)
• Capital gains (short-term and long-term)
• Social Security benefits
• Veterans' benefits
• Workers' compensation
• Unemployment benefits
• Lump-sum annual leave payout from your final federal paycheck

Part-Time and Seasonal Work

Part-time W-2 employment is the simplest scenario to plan around. You know your hourly rate and can estimate your annual earnings with reasonable precision. If you're earning $20/hour and work 20 hours per week, your annual earnings are approximately $20,800 — below the $24,480 threshold and safe.

The risk comes from overtime, bonuses, or rate increases that push you past the limit unexpectedly. A retiree earning $22,000 in base wages who picks up $4,000 in holiday overtime crosses the threshold and triggers a $760 annual supplement reduction.

Consulting and Self-Employment

Self-employment earnings are calculated differently from wages. The earnings test uses your net self-employment income — gross revenue minus ordinary and necessary business expenses. If you gross $50,000 in consulting fees but have $30,000 in legitimate business expenses, your net self-employment income is $20,000, which is below the limit.

This matters for retirees who set up LLCs or sole proprietorships for consulting work. Deductible business expenses — home office, travel, professional development, equipment, professional liability insurance — reduce the earnings that count toward the test.

One important distinction: the earnings test uses your actual net self-employment income, not your adjusted gross income (AGI) from your tax return. Self-employment tax deductions and retirement plan contributions reduce your AGI but don't reduce your net earnings for earnings test purposes.

Federal Reemployment

Some retirees return to federal service on a temporary or part-time basis. If you're reemployed by a federal agency, your gross salary counts toward the earnings test — the full amount before any dual-compensation offset is applied.

Under dual-compensation rules, your salary from the reemployment position may be offset by your annuity (depending on the type of appointment and any waiver). But for earnings test purposes, OPM counts the gross salary, not the reduced amount you actually receive. This trips up retirees who assume their smaller take-home pay is what counts.

The TSP Strategy

TSP withdrawals are the most powerful tool for earnings-test-exempt income because they provide flexible, controllable cash flow that doesn't affect the supplement.

A retiree who needs $4,000/month in total income and receives $2,000 from the FERS annuity plus $1,300 from the supplement can withdraw $700/month from the TSP to close the gap — with zero impact on the supplement. If that same retiree instead took a part-time job paying $700/month ($8,400/year), the supplement would also be unaffected because the wages remain below the earnings limit, but the tax treatment would differ.

The distinction matters when income needs are higher. A retiree who needs $6,000/month and can only cover $3,300 from annuity plus supplement has a $2,700/month gap. Filling that entirely from TSP withdrawals preserves the full supplement. Filling it from wages would mean earning $32,400/year — exceeding the limit by $7,920 and triggering a $3,960 annual reduction.

Traditional TSP withdrawals are taxable as ordinary income, so they affect your tax bracket and potentially your Medicare IRMAA bracket. But they don't affect the supplement. Roth TSP withdrawals are even better positioned — they're both earnings-test-exempt and tax-free.

Investment Income and Rental Properties

All passive income streams are exempt from the earnings test:

Rental income: Rental income from investment properties is listed as exempt from the earnings test. Keep records describing the source of the income in case OPM asks for clarification.

Dividends and capital gains: Interest from savings accounts, dividend distributions from stock portfolios, capital gains from selling investments — all exempt. A retiree who realizes $50,000 in capital gains from selling appreciated stock has no supplement reduction.

Royalties and licensing fees: Income from intellectual property, book royalties, patent licensing, or mineral rights is generally treated as passive income and excluded from the earnings test.

The Hybrid Approach

Many retirees combine exempt and non-exempt income sources to maximize total income while keeping earned income below the threshold:

• $2,200/month FERS annuity (exempt)
• $1,300/month supplement (exempt)
• $1,000/month TSP withdrawal (exempt)
• $1,500/month part-time consulting ($18,000/year — below limit)
• $500/month rental income (exempt)

Total monthly income: $6,500, with zero supplement reduction.

The same retiree earning $6,500 entirely from consulting ($78,000/year) would lose their entire supplement to the earnings test.

Planning the Transition to Post-MRA Earnings

For special category retirees (LEOs, firefighters, ATCs), the earnings test doesn't apply until they reach their standard MRA. They can earn unlimited active income during the pre-MRA years.

Once the earnings test kicks in — either at retirement for standard retirees or at MRA for special category employees — the key planning decision is whether the additional earned income above the threshold is worth the supplement reduction, net of taxes.

A retiree earning $40,000 in wages (exceeding the limit by $15,520) faces a supplement reduction of $7,760. But they also earned $15,520 more than the threshold amount. After the reduction, they're still $7,760 ahead — minus the income taxes on the additional wages. In most tax brackets, the net gain is positive, so exceeding the limit isn't necessarily a bad outcome.

The FERS Special Retirement Supplement Guide includes an earnings test calculator that models different income scenarios — wages only, self-employment, hybrid passive/active — and shows the net impact on your supplement, total income, and estimated tax liability.
