Social Security counts your highest 35 years of earnings
Social Security bases your retirement benefit on your 35 highest-earning years of work. The Social Security Administration (SSA) looks back through your entire work history, picks out the 35 years where you earned the most, and uses those to calculate what you receive each month.
If you worked fewer than 35 years, the SSA counts the missing years as zeros. This means that taking time out of the workforce — for caregiving, illness, or other reasons — can lower your benefit amount. The more years you work after age 60, the more likely you are to replace a lower-earning year in that 35-year calculation.
Your earnings are adjusted for inflation using a formula that accounts for wage growth in the year you turn 60. This means your earlier, lower-paying jobs are brought up to a more current value before the calculation happens, so you are not penalized for earning money decades ago.
Key Takeaways
- Social Security uses your 35 highest-earning years to calculate your monthly benefit, and years with no earnings count as zero.
- If you worked fewer than 35 years, missing years lower your benefit amount, but you can raise it by working longer.
- Your past earnings are adjusted for inflation so that older, lower wages are brought up to a more current value in the calculation.
- You can view your own earnings record on your Social Security account at ssa.gov to see which years are being counted.
- Working past your full retirement age can replace a lower-earning year and increase your benefit by up to 8 percent per year until age 70.
What happens if you did not work 35 years
If you have fewer than 35 years of earnings on record, the SSA fills in the missing years with zeros. For example, if you worked 30 years, five years of zeros are included in the calculation. Those five zeros pull down your average earnings and reduce your monthly benefit.
This affects people who took extended time away from paid work — parents who stayed home with children, people who were ill or disabled for a period, or those who immigrated to the United States later in life. Each missing year of earnings reduces your benefit by roughly one-thirty-fifth of your average.
You can still receive Social Security even with fewer than 35 years of work, as long as you have at least 10 years (40 credits) of covered earnings. But your benefit will be lower than someone with a full 35-year record.
How working longer can increase your benefit
If you continue working after age 60, each new year of earnings may replace a lower-earning year from your past. The SSA recalculates your benefit every year based on your updated earnings record. If your most recent year of earnings is higher than one of the years currently in your 35-year calculation, that older, lower year drops out.
This is one reason why delaying retirement can raise your benefit. Working longer gives you the chance to replace zeros or low-earning years. Even if your recent earnings are not dramatically higher than your past earnings, the replacement effect still helps.
Additionally, if you delay claiming benefits past your full retirement age, your monthly payment increases by 8 percent per year until you reach age 70. This delayed retirement credit is separate from the recalculation of your 35-year average, so both effects work together to raise your benefit.
How to check which years are counted in your record
You can see your own earnings record by creating an account at ssa.gov and logging into "my Social Security." The website shows your year-by-year earnings history as the SSA has it on file. You can review whether the amounts look correct and whether any years are missing.
If you spot an error — a year with no earnings when you know you worked, or an amount that seems too low — you can report it to the SSA. You will need to provide proof, such as old tax returns, W-2 forms, or pay stubs. The SSA has a time limit for correcting errors, so it is worth checking your record sooner rather than later.
If you do not have an online account yet, you can also request a paper copy of your earnings record by calling the SSA at 1-800-772-1213 or visiting your local Social Security office.
Special rules for government workers and non-covered employment
If you worked for a federal, state, or local government and did not pay Social Security taxes, those years do not count toward your 35-year record. The same applies to work you did outside the United States, unless there was a totalization agreement between the U.S. and that country.
Some people have both covered employment (where they paid Social Security taxes) and non-covered employment. In those cases, only the covered years count. This can result in a lower benefit for people who spent part of their career in a job that did not participate in Social Security.
If you receive a pension from non-covered government work, the SSA may reduce your Social Security benefit under rules called the Government Pension Offset or the Windfall Elimination Provision. These rules are complex and depend on your specific work history, so it is worth discussing your situation with the SSA before you claim.
How the 35-year calculation affects your claiming decision
Understanding the 35-year rule can help you decide when to claim benefits. If you are approaching 35 years of covered work and are still employed, working a few more years may noticeably increase your benefit by replacing low-earning years. If you already have well over 35 years of strong earnings, additional work years may have less impact on the calculation itself, though the delayed retirement credits (8 percent per year) still explore.
If you took time out of the workforce and have fewer than 35 years of earnings, you might benefit from working longer if you are able to do so. Even part-time work can add a year of covered earnings and replace a zero in your calculation.
The SSA can give you a benefit estimate that shows what you would receive at different claiming ages. This estimate is based on your actual earnings record and accounts for the 35-year calculation, so it reflects your real situation rather than a generic example.
Frequently Asked Questions
Does working part-time count toward the 35 years?
Yes. Social Security counts any year in which you earned at least $1,470 (in 2023) as a covered year, regardless of whether you worked full-time or part-time. You do not need to work a full year or earn a certain amount to have that year count — you just need to reach the annual threshold. The actual amount you earned that year is what goes into your benefit calculation.
Can I remove a low-earning year from my record?
No, you cannot remove a year from your record. However, if you continue working, a new higher-earning year can replace a lower-earning year in the 35-year calculation. The SSA automatically uses your 35 highest years, so you do not need to do anything — the replacement happens when your record is updated.
What if I worked in another country?
Work in another country generally does not count toward Social Security unless the U.S. has a totalization agreement with that country. Totalization agreements allow work in both countries to count toward benefits. If you worked abroad, contact the SSA to find out whether your work counts and how it affects your benefit.
Does military service count toward the 35 years?
Military service counts toward Social Security if you served on active duty after 1956. The SSA gives you credit for military wages even if you did not pay Social Security taxes during your service. If you served before 1957, you may still receive credit under different rules — contact the SSA for details about your specific service dates.
Can I see how much each year of work affects my benefit?
The SSA does not break down the exact dollar impact of each year, but your benefit estimate shows what you would receive based on your current earnings record. If you work another year and request a new estimate, you can compare the two to see how that additional year changed your benefit. The my Social Security website updates your estimate annually.
