A Social Security retirement benefit is built from a lifetime of reported earnings, and a single missing or wrong year can quietly shrink the eventual check. Wages that never posted to the record, an employer that reported the wrong amount, or income filed under a mistyped Social Security number all lower the average the agency uses to set a benefit. A free my Social Security account is the fastest way to surface those gaps — and catching them early, while pay stubs and W-2s still exist, is what makes them fixable at all.
Why the earnings record drives the benefit
Social Security calculates a retired worker’s benefit from the 35 highest-earning years, indexed for wage growth, so every year on the record either raises or dilutes the final figure. A year that shows zero earnings when a person actually worked drags that 35-year average down, and the shortfall follows the benefit for life once payments begin.
The record is only as accurate as what employers transmit. Payroll mistakes, a name change that never reached the agency, and earnings reported under a wrong or transposed number are common ways a year goes missing or lands on the wrong file. Self-employment income that was underreported at tax time can leave a gap as well. Because the agency posts what it receives, an error at the source becomes an error in the benefit unless someone flags it.
Certain life events make a gap more likely and are worth a deliberate check. A name change after marriage or divorce that never reached the agency can cause wages to post under an old name, and a mismatch between a worker’s information and an employer’s filings can leave a year unposted for months. Workers who change jobs often, hold more than one job at a time, or earn self-employment income alongside regular wages have more moving parts in their record and, with them, more chances for a year to land wrong.
A my Social Security account lays the record out year by year. The agency’s guidance urges workers to review the earnings record regularly against their own tax documents, since the person who earned the wages is the one most likely to spot a year that reads wrong.

What the online account shows
Creating a free my Social Security account gives a worker access to the full Social Security Statement, which lists earnings for every year of work alongside estimates of future retirement, disability, and survivor benefits. The statement is the same document the agency once mailed on paper; the online version simply makes it available at any time and updates as new earnings post.
Reviewing it is a matter of comparing the posted figure for each year against personal records — W-2 forms for employees, or tax returns and Schedule SE for the self-employed. A year that shows far less than was actually earned, or a blank where there should be wages, is the signal to act. The statement also flags the most recent years, which are the ones most likely to still be pending or newly corrected.
Checking early in a career matters as much as checking near retirement. An error found decades after the fact can be far harder to prove once employers have closed, records have been discarded, and memories have faded. The account turns an annual review into a quick habit rather than a scramble at 66.
How to fix an error before proof disappears
When the record is wrong, the agency will correct it, but the burden of proof sits with the worker. Its guidance on correcting an earnings record asks for documentation such as a W-2, a pay stub, or a tax return showing the correct amount. With solid paperwork, a fix can often be requested by phone at 1-800-772-1213, in person, or in some cases online.
Timing is where many corrections are won or lost. Ordinarily, an earnings entry can be changed only within three years, three months, and fifteen days after the end of the year the wages were paid. After that window, the agency will still correct genuine mistakes — such as amounts confirmed by IRS tax returns, employer omissions, or errors plain on the face of the record — but the process grows more demanding as evidence ages.
For anyone without the original documents, Form SSA-7008, the request for correction of earnings record, lets a worker describe the employer, the period, and the wages in question so the agency can investigate. It is the formal route when a pay stub or W-2 cannot be located, and it is far more effective when filed while the employer still exists and payroll records can be retrieved.
The through-line in the agency’s own instructions is speed. An earnings record is easiest to correct while the wages are recent and the proof is close at hand, and a benefit built on an accurate record is worth more, month after month, than one quietly diminished by a year that was never fixed.
