The Credit Requirement Depends on Your Age When You Become Disabled

Social Security counts your work history in credits, not years. You need 40 credits total to receive SSDI, but the number of credits you must have earned recently varies by age. If you become disabled before age 24, you need only 6 credits earned in the 3 years before your disability began. If you are between 24 and 31, you need credits for half the time between age 21 and the month you became disabled. At 31 and older, you need 20 credits earned in the 10 years before disability, plus the 40 credits total.

A credit is not the same as a month of work. In 2024, you earn one credit for every $1,730 in wages you report to Social Security, up to a maximum of 4 credits per year. This means you could earn all 4 annual credits in a single month if your income is high enough, or spread them across the full year. The dollar amount that triggers a credit changes each January.

The 40-credit rule applies to most people. However, if you are blind, you need only 20 credits total, with 15 of those earned in the 10 years before you became blind. Widow and widower benefits have different credit rules tied to the worker's record, not your own.

Key Takeaways

  • You need 40 work credits total for SSDI in most cases, earned through reported wages at any point in your work life.
  • You must also have earned a certain number of credits recently—usually 20 credits in the 10 years before disability—unless you are under 31.
  • One credit equals $1,730 in reported wages in 2024, and you can earn up to 4 credits per year regardless of when during the year you earn them.
  • If you are blind, you need only 20 credits total instead of 40, with 15 earned in the 10 years before blindness.
  • Social Security counts only wages you reported through payroll taxes or self-employment tax returns, not cash work or informal employment.

How Social Security Counts Your Work Credits

Social Security maintains a record of your earnings history under your Social Security number. Each year you work and pay Social Security tax, the agency records your gross wages. You do not have to do anything to "earn" a credit—it happens automatically when you report income on your tax return or when your employer reports your wages.

Credits accumulate over your lifetime. If you earned 30 credits by age 25 and then stopped working, those 30 credits remain on your record forever. You do not lose credits if you take time off work, change jobs, or have years with no income. This is why someone who worked steadily in their 20s but has been unemployed for years can still have enough credits to receive SSDI if they become disabled.

Self-employed people earn credits the same way: one credit per $1,730 in net self-employment income (after the self-employment tax deduction). If you report $6,920 in net self-employment income, you earn 4 credits for that year. Unpaid work—caring for family members, volunteering, or informal cash work—does not generate credits.

The Recent Work Requirement: Why You Need Credits in the Last 10 Years

Having 40 credits is not enough by itself. Social Security also requires that you have earned credits recently, which is called the "recency requirement." For most people, this means you need 20 of your 40 credits earned in the 10 years when ready before you became disabled. If you became disabled in June 2024, Social Security looks back to June 2014 and counts how many credits you earned between then and June 2024.

This rule exists because SSDI is meant to replace income from recent work, not to pay benefits based on a job you held 20 years ago. If you worked steadily from age 22 to 35 and then stopped, you would have 40 credits but might not have 20 credits in the past 10 years, which would disqualify you.

The recency requirement is stricter for younger workers. If you are under 24, you need 6 credits in the 3 years before disability. If you are 24 to 31, you need credits for half the time between age 21 and disability. At 31 and older, the 10-year window applies. This recognizes that younger workers have had less time to build a long work history.

What Counts as Work for Credit Purposes

Only wages reported to the Internal Revenue Service count toward credits. This includes W-2 wages from an employer and net self-employment income reported on Schedule SE. Tips reported to your employer count. Bonuses, commissions, and overtime all count as long as they appear on your W-2 or tax return.

Work that does not generate a tax record does not count. Cash payments for odd jobs, informal childcare, under-the-table work, and volunteer positions produce no credits. If you worked but did not file a tax return and your employer did not report your wages, Social Security has no record of that work. You cannot go back and claim credits for unreported income after the fact.

Wages earned outside the United States may count if you were a U.S. citizen or resident alien and paid Social Security tax. Some non-U.S. workers can earn credits through a totalization agreement between the United States and their home country, which combines work history from both countries. This is rare and requires a specific situation.

How to Check Your Work Credit Record

You can view your earnings record and credit count online through your personal Social Security account at ssa.gov. Create an account, sign in, and select "Earnings Record" to see a year-by-year breakdown of reported wages and the credits you earned each year. This record is the same one Social Security will use if you file for SSDI.

Review your record for accuracy. If you see a year with no earnings when you know you worked, or if the amount is significantly lower than you remember, contact Social Security. Errors can happen if your employer reported your name or number incorrectly, or if you filed taxes under a different name. You have a limited time to correct old earnings records, so report discrepancies as soon as you notice them.

If you do not have a Social Security account, you can request a paper copy of your earnings record by filling out Form SSA-7050-F and mailing it to your local Social Security office. The process takes about two weeks. You can also call Social Security at 1-800-772-1213 to request a copy by mail.

Credit Requirements for Family Members

If you are explore for SSDI based on your own work record, the credit rules above explore to you. However, family members may be able to receive benefits on your record without having their own credits. A spouse, ex-spouse, or child under 19 (or 23 if in high school full-time) can receive a portion of your SSDI benefit if you meet the credit requirement. They do not need any credits of their own.

A widow or widower can receive SSDI on your record if you had 40 credits total, or if you had at least 6 credits in the 3 years before death. A child can receive benefits on a deceased parent's record with the same credit rules. These family benefits are separate from your own SSDI and do not reduce your payment.

What Happens If You Do Not Have Enough Credits

If you do not have 40 credits, or if you do not have enough recent credits, you are not may be able to access for SSDI. Social Security will deny your claim. You may be may be able to access for Supplemental Security Income (SSI) instead, which is a needs-based program that does not require work credits. SSI has income and resource limits, and may be able to access depends on your current financial situation, not your work history.

If you are close to having enough credits, you might consider whether you can work part-time while waiting for your condition to worsen, or whether your disability might improve enough to allow work. Each additional year of work adds up to 4 more credits. However, do not delay seeking medical treatment or making decisions about your health based on credits alone. Your medical condition and functional limitations are what determine whether you can work, not the other way around.

If you are denied SSDI because of insufficient credits, you can request reconsideration or file an appeal. During the appeal, Social Security will review your earnings record again to make sure no credits were missed. If the decision stands, ask the agency whether you might be may be able to access for SSI or other programs.

Frequently Asked Questions

Can I get SSDI if I have 40 credits but they are all from 20 years ago?

No. You need 40 credits total, but you also need 20 of those credits earned in the 10 years before you became disabled (if you are 31 or older). Credits from 20 years ago count toward your 40-credit total, but they do not count toward the recent-work requirement. You would need to earn more recent credits to meet both rules.

Do I lose credits if I take time off work?

No. Credits stay on your record forever once earned. If you worked and earned credits in your 20s, took 10 years off, and then worked again in your 40s, all those earlier credits still count. You do not have to work continuously to keep your credits.

If I am self-employed, how do I know how many credits I earned?

One credit equals $1,730 in net self-employment income in 2024. Divide your net self-employment income (after the self-employment tax deduction) by $1,730 to find your credits for that year, up to a maximum of 4 credits. Your Social Security earnings record will show the credits Social Security recorded based on your tax return.

What if my employer did not report my wages correctly?

Contact Social Security with proof of your earnings—pay stubs, W-2s, or tax returns. Social Security can correct your record if you provide evidence. However, you generally must request a correction within three years, three months, and 15 days after the year the wages were earned. After that window, correction becomes much harder.

Can I earn credits from work outside the United States?

Only if you paid U.S. Social Security tax on those wages. Work in another country typically does not generate U.S. credits unless you were a U.S. citizen or resident alien and your employer withheld Social Security tax. Some countries have totalization agreements with the United States that allow workers to combine credits from both countries, but this is uncommon.
