Work credits don't expire, but there's a time limit on when you can use them

Your work credits — the credits you earn by paying Social Security taxes — stay on your record forever. Social Security does not delete them after a certain number of years. However, there is a separate rule about when you can use those credits to may have access to for SSDI: you must have earned enough credits recently enough. This is called the "recency requirement," and it is what actually limits how long your work history counts.

The recency requirement means you need to have worked and earned credits within a specific window before you explore for SSDI. If you stop working and do not earn new credits for too long, you may no longer meet the requirement — even though your old credits are still there on your record. Understanding this difference matters because it affects whether your past work counts toward your claim.

Key Takeaways

  • Work credits themselves never expire and stay on your Social Security record for your entire life.
  • To may have access to for SSDI, you must have earned enough credits within a specific recent time period, which varies based on your age when you become disabled.
  • Generally, you need to have worked within the last 10 years to meet the recency requirement, though younger workers have different rules.
  • If you stop working and your credits become too old, you can regain recency by returning to work and earning new credits.
  • Social Security counts your entire work history when calculating your benefit amount, even if some credits are very old.

The difference between having credits and meeting the recency requirement

Social Security tracks two separate things: the total number of credits you have earned in your lifetime, and whether those credits are recent enough. You need both to may have access to for SSDI.

Most people need 40 credits total to may have access to for SSDI, and you earn one credit for every $1,730 of wages in a year (this dollar amount changes each year). If you earned $6,920 in a single year, you would earn the maximum of four credits for that year. Once you have earned those credits, they stay on your record permanently.

But Social Security also requires that you have worked recently. This is the recency requirement. If your last credit was earned 15 years ago, you have the credits, but you do not meet the recency requirement — so you cannot claim SSDI based on that work history alone.

How the recency requirement works based on your age

The recency requirement depends on how old you are when you become disabled. Social Security uses different rules for different age groups because younger workers have had less time to build a work history.

If you are 31 or older when you become disabled, you generally need to have earned 20 of your 40 credits within the last 10 years. This means at least half of your required credits must be recent. If you are between 24 and 30, the rule is slightly different: you need credits for half of the time between age 21 and the time you became disabled, with a minimum of 20 credits. If you become disabled before age 24, you need only 6 credits earned within the 3 years before you became disabled.

These rules exist because younger workers have not had as much time to work. A 23-year-old cannot reasonably have 40 credits, so Social Security adjusts the requirement downward.

What happens if your credits become too old

If you stop working and your most recent credit falls outside the recency window, you lose the ability to use your work history for SSDI — at least temporarily. This does not mean your credits disappear. It means you cannot claim SSDI based on that work history until you earn new credits that bring you back into the recency window.

For example, suppose you are 35 years old and you worked steadily until age 30, earning 40 credits. You then stopped working. By age 40, your most recent credit is 10 years old, which is right at the edge of the recency window. By age 41, your most recent credit is 11 years old, and you no longer meet the recency requirement. If you became disabled at age 41, you could not claim SSDI based on that work history.

However, if you returned to work for even one year and earned new credits, you would regain recency. Your old credits would still be there, and your new credits would pull your work history back into the may have access to window.

How old credits affect your benefit amount

Even though you need recent credits to may have access to for SSDI, Social Security counts your entire work history — including very old credits — when calculating how much money you receive each month. This is different from the recency requirement, which only determines whether you can claim at all.

Social Security looks at your highest 35 years of earnings and uses that to calculate your Primary Insurance Amount, or PIA. This is the base number used to determine your monthly SSDI payment. If you worked 40 years, Social Security drops your lowest 5 years of earnings. If you worked only 20 years, Social Security counts those 20 years and treats the remaining 15 years as zero.

This means that very old work history does count toward your benefit amount, even if it happened decades ago. A year when you earned high wages 30 years ago could still be one of your top 35 years and could increase your monthly payment.

Regaining recency if you have been out of work

If you have been out of work long enough that your credits no longer meet the recency requirement, you can regain recency by returning to work. You do not need to earn 40 new credits — you just need to earn enough new credits to bring your work history back into the may have access to window.

For someone 31 or older, this usually means earning at least one new credit within the last 10 years. One credit requires $1,730 in wages (as of 2024), which is a modest amount. Even part-time work for a few months could be enough to regain recency.

Once you have regained recency, you can claim SSDI if you also meet the medical requirements. Your old credits are still there, and they still count toward your total of 40 and toward your benefit calculation.

What to do if you are unsure about your work credits

You can request a Statement of Earnings from Social Security, which shows every year you worked and how many credits you earned. This is a free document that you can order online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office.

The Statement of Earnings also shows if there are any years where Social Security has no record of your work. If you believe you worked in a year that does not appear on the statement, you can ask Social Security to correct it. You will need to provide proof, such as old tax returns or W-2 forms.

If you are thinking about explore for SSDI, reviewing your Statement of Earnings first can help you understand whether your work history meets the recency requirement. This can save you time and help you know what to expect.

Frequently Asked Questions

Can I use work credits I earned 20 years ago to may have access to for SSDI?

The credits themselves never disappear, but whether you can use them depends on your age and how recently you worked. If you are 31 or older and your most recent credit is more than 10 years old, you do not meet the recency requirement. However, if you earned new credits within the last 10 years, those old credits still count toward your total of 40.

What if I worked for many years but then took time off to raise children?

Years with no earnings do not erase your old credits, but they do make your work history older. If you stopped working 12 years ago and have not worked since, your most recent credit is 12 years old, which is outside the 10-year recency window for someone 31 or older. Returning to work for even a short time would bring you back into recency.

Do my work credits expire if I don't use them?

Work credits themselves do not expire. They stay on your Social Security record forever. However, the rule about when you can use them for SSDI does have a time limit — the recency requirement. This is a rule about timing, not about the credits disappearing.

If I become disabled, will Social Security look at all my work history or just recent years?

Social Security will look at all your work history to calculate your monthly benefit amount. However, to determine whether you can claim SSDI at all, they will check whether you meet the recency requirement, which focuses on recent work. Both matter, but they serve different purposes.

Can I check how many credits I have right now?

Yes. You can create a my Social Security account at ssa.gov and view your Statement of Earnings online. You can also call 1-800-772-1213 or visit a local Social Security office to request a printed copy. The statement shows your credits year by year and is free to obtain.
