7. Allowing Errors on Your Earnings Record to Persist

Your Social Security benefit is determined by your Average Indexed Monthly Earnings (AIME), which calculates your highest 35 years of inflation-adjusted earnings. If you do not have a full 35 years of work history, the administration fills the missing years with zeros, which violently drags down your average and results in a lower Primary Insurance Amount (PIA).

Many workers assume the government possesses flawless records of their lifetime employment. In reality, administrative errors, name changes, clerical mistakes by former employers, and misreported W-2s frequently result in missing income years. If a high-earning year is mistakenly recorded as a zero, your permanent retirement benefit will suffer.

You have a limited window—generally three years, three months, and fifteen days following the year the income was earned—to correct your earnings record, though exceptions exist for obvious employer fraud or easily verifiable clerical errors. You must proactively create an account at the official Social Security Administration website, download your statement annually, and verify that your recorded earnings match your actual tax returns.
