The SRS earnings test is narrower than most federal employees expect. It only counts one kind of income: earned income from work. Not investment income. Not pension income. Not withdrawals from your Thrift Savings Plan. Just paychecks and the self-employment equivalent.

That narrow definition is also why the SRS can survive a high-income retirement for some federal employees and disappear entirely for others — even when their total income is similar.

What counts as earned income.

The Social Security Administration defines earned income for earnings-test purposes as wages, tips, and other compensation for personal services, plus net earnings from self-employment. OPM uses the same definition for the SRS. In plain terms:

  • W-2 wages. Every dollar of wages from a job, before any deductions, counts toward the test. Bonuses count. Overtime counts. The exempt amount is set against the gross wage total.
  • Net self-employment earnings. If you receive a 1099-NEC or 1099-K and pay self-employment tax, the net earnings count toward the test after the deductible portion of SE tax.
  • Director fees, commissions, and certain other compensation.These count if they’re paid for personal services in a trade or business.

What doesn’t count.

The list of income that doesn’t trigger the earnings test is larger than most people assume, and it covers most of the income sources retirees rely on:

  • Investment income. Interest, dividends, capital gains, and distributions from taxable brokerage accounts are not earned income.
  • TSP withdrawals and IRA distributions.These are not earned income regardless of how large they are. They’re not wages; they’re transfers of your own saved money.
  • Pension payments, including the FERS annuity itself. Even if your FERS annuity is your largest single income source, it doesn’t trigger the earnings test.
  • Social Security benefits.Already drawing Social Security does reduce the SRS dollar for dollar, but that’s a separate offset, not an earnings-test issue.
  • Rental income in most cases. Rental income is generally treated as passive income and does not count toward the earnings test, although the rules around real-estate professionals are more complex.
  • Royalties, in most cases. Royalties for the creation of intellectual property are not earned income unless you are a dealer in those assets.
  • Gifts and inheritances. Transfers, not earnings.

The gray zone: self-employment.

Self-employment is where most disputes arise. If you receive a 1099 for consulting work, that income is generally earned income for earnings-test purposes — subject to the self-employment adjustments. If you receive a 1099 for the sale of a product that you made once and don’t do again, the line is harder. If you receive a K-1 from a partnership in which you’re a passive partner, the income may be passive and not subject to the test.

If you’re planning a consulting practice or a side business in retirement, the SRS earnings test should be in the conversation before you sign the first contract.

Why this distinction is the planning lever.

Most federal retirees I work with have a TSP balance that grows through their late 50s and early 60s. The SRS often ends at 62, just as the retiree is beginning to draw TSP income. The structural coincidence is useful: TSP withdrawals don’t count toward the earnings test, so a retiree who structures post-retirement income through TSP first and earnings second will keep more of the SRS.

The wrong way to do this is to take a high-paying job and use TSP withdrawals to cover the SRS shortfall caused by the earnings test. The right way is to plan the income mix up front, so the SRS and the TSP are doing different jobs at different times.

A practical decision tree.

If you’re under 62 and eligible for the SRS, the question isn’t really “how much will I earn?” It’s “how much will I earn from work, separately from everything else?” The answer to that question determines whether the SRS arrives intact, partial, or not at all.
