You can earn unlimited income while collecting Social Security starting the month you reach your full retirement age, which falls between 66 and 67 depending on the year you were born. Before that birthday, the Social Security Administration reduces your benefits if your work earnings exceed an annual cap. Once you hit full retirement age, the cap disappears for good, and no amount of wages or self-employment profit will shrink your monthly check.
Find Your Full Retirement Age First
The age when the earnings limit ends is tied entirely to your birth year:
- Born 1943–1954: 66
- Born 1955: 66 and 2 months
- Born 1956: 66 and 4 months
- Born 1957: 66 and 6 months
- Born 1958: 66 and 8 months
- Born 1959: 66 and 10 months
- Born 1960 or later: 67
For each birth year from 1955 through 1959, full retirement age climbs by two months.1eCFR. 20 CFR 404.409 – What Is Full Retirement Age? You can claim benefits as early as age 62, but doing so locks in both a permanently reduced monthly payment and the earnings test until you reach full retirement age.2Social Security Administration. You Can Receive Benefits Before Your Full Retirement Age
What Counts as Earnings
The earnings test only looks at money you actively earn through work. For employees, that means gross wages including bonuses, commissions, and vacation pay. For self-employed workers, it means net profit after allowable expenses.3Social Security Administration. Receiving Benefits While Working
Most retirement income is ignored. Pension payments, annuities, investment dividends, savings account interest, capital gains, and veterans benefits do not count toward the earnings limit.3Social Security Administration. Receiving Benefits While Working You could collect a six-figure pension alongside Social Security without triggering any reduction. The line that matters is whether the money came from current work or from investments and retirement accounts.
One catch: severance pay and lump-sum vacation payouts tied to your employment generally count as wages even if you receive them after you’ve stopped working. A large severance check in your retirement year can push you over the annual limit.
Before Full Retirement Age: The Annual Limit
If you claim benefits before the calendar year you reach full retirement age, Social Security withholds $1 for every $2 you earn above the annual limit. In 2026, that limit is $24,480.4Social Security Administration. Exempt Amounts Under the Earnings Test If you earn $34,480, you’re $10,000 over, so Social Security withholds $5,000 in benefits that year.
The withholding doesn’t come as a small deduction from each check. Social Security withholds entire monthly payments until the total reduction is satisfied. If you owe $5,000 back and your monthly benefit is $1,800, you’d receive nothing for roughly three months, get a partial check to cover the remainder, and then resume full payments. Many people expect a steady haircut and are caught off guard by months of zero income.
The first year you retire mid-year gets special treatment. You may have already earned above the annual limit before ever claiming benefits, so Social Security applies a monthly test in that first year. In any month where you earn $2,040 or less (in 2026) and don’t perform substantial self-employment work, you get your full benefit for that month, regardless of what you earned earlier in the year.5Social Security Administration. Code of Federal Regulations 404.435 – Excess Earnings; Grace Year Defined This monthly test applies only once. After that, the annual test takes over.
The Year You Reach Full Retirement Age
The rules loosen sharply during the calendar year you actually turn your full retirement age. The annual limit jumps to $65,160 in 2026, and the withholding rate drops to $1 for every $3 earned above it.6Social Security Administration. Cost-of-Living Adjustment (COLA) Information
Only the months before your birthday count. If your full retirement age is 67 and you turn 67 in September, Social Security only looks at your earnings from January through August. Anything you make in September or later is disregarded, even a large year-end bonus.4Social Security Administration. Exempt Amounts Under the Earnings Test Most people working at moderate income levels won’t lose any benefits at all in the transition year.
After Full Retirement Age: No More Limit
Starting the month you reach full retirement age, the earnings test disappears. You can earn any amount from any source, and Social Security will pay your full benefit without withholding a penny. The change is permanent.3Social Security Administration. Receiving Benefits While Working
Money withheld in earlier years isn’t gone. When you reach full retirement age, Social Security recalculates your monthly benefit to credit you for every month where your check was reduced or withheld under the earnings test. Your ongoing payment goes up to reflect those lost months, and over time you recoup what was withheld through higher checks for the rest of your life.7Social Security Administration. Program Explainer: Retirement Earnings Test The recalculation doesn’t undo the permanent reduction from claiming before full retirement age, but it does adjust for the specific months withheld due to earnings.
Social Security also reviews your earnings record each year after full retirement age. If your recent wages replace a lower-earning year in the 35-year calculation used to set your benefit, your payment automatically increases.3Social Security Administration. Receiving Benefits While Working
“Unlimited” Isn’t Tax-Free
Reaching full retirement age ends Social Security’s withholding, but a bigger paycheck can still cost you through federal income tax on your benefits. The IRS uses a formula called combined income (your adjusted gross income, plus tax-exempt interest, plus half your Social Security benefits) to determine how much of your benefit is taxable.
The thresholds are set by statute and have never been indexed for inflation:
- Single filers: combined income between $25,000 and $34,000 makes up to 50% of benefits taxable; above $34,000, up to 85% becomes taxable.
- Married filing jointly: combined income between $32,000 and $44,000 makes up to 50% taxable; above $44,000, up to 85% becomes taxable.
These amounts come directly from the tax code.8Office of the Law Revision Counsel. 26 USC 86 – Social Security and Tier 1 Railroad Retirement Benefits Married couples filing separately who live together face the harshest treatment, with up to 85% of benefits taxable starting at $0 in combined income.9Internal Revenue Service. Publication 915, Social Security and Equivalent Railroad Retirement Benefits A retiree pulling in $50,000 from a part-time job while collecting Social Security will almost certainly land in the 85% taxable bracket.
Higher Income Can Raise Your Medicare Premiums
Medicare Part B and Part D premiums are income-tested through a surcharge called IRMAA, the Income-Related Monthly Adjustment Amount. If your modified adjusted gross income from two years earlier exceeds the thresholds, you pay more each month. For 2026, the brackets start at $109,000 for individual filers and $218,000 for joint filers.10Centers for Medicare & Medicaid Services (CMS). 2026 Medicare Parts A and B Premiums and Deductibles
The surcharges climb steeply. A single filer with income between $109,000 and $137,000 pays an extra $81.20 per month for Part B plus $14.50 for Part D. At the top bracket of $500,000 or more, the combined monthly surcharge exceeds $575 per person, so a married couple both on Medicare could pay double.
The two-year lookback is what catches people. Working full-time in the year before retirement can inflate your Medicare premiums two years later. You can request an adjustment after a life-changing event like retirement, but you have to contact Social Security directly to start that process.
