You need 40 work credits total, with 20 earned in the 10 years before you become disabled

The amount of time you've paid into Social Security through payroll taxes determines whether you can receive SSDI. Social Security measures this in work credits, not years of work. You earn one credit for every $1,550 of wages you report to Social Security in 2024 (this dollar amount changes each year). You can earn a maximum of four credits per year, which means the fastest you can build toward SSDI is one credit per quarter.

To may have access to for SSDI, you need 40 credits total. More importantly, you must have earned 20 of those 40 credits in the 10-year period when ready before you become disabled. This second rule is what actually stops most people from may have access to—not the total number of credits, but the recency of your work.

If you became disabled in 2024, Social Security looks back to 2014 and counts how many credits you earned between January 2014 and December 2023. You need at least 20 of those credits. If you have 40 credits but only 15 of them fall in that 10-year window, you do not may have access to for SSDI, even though you have enough total credits.

Key Takeaways

  • You earn one work credit for approximately $1,550 in Social Security wages per year; the exact amount changes annually and is set by Social Security each October.
  • You need 40 work credits total, but the critical requirement is 20 credits earned in the 10 years before your disability began.
  • If you worked steadily for 10 years at any point in your life, you almost certainly have enough recent credits to meet this requirement.
  • Self-employed income counts toward work credits the same way W-2 wages do, as long as you report it to Social Security and pay self-employment tax.
  • Your work history is verified through your Social Security record, which you can review free at ssa.gov to catch errors before you file.

What counts as a work credit

A work credit is earned when you pay Social Security payroll tax on your wages. If you are a W-2 employee, your employer withholds this tax automatically. If you are self-employed, you pay it as self-employment tax when you file your tax return. Either way, Social Security records the wages you report and converts them into credits.

The dollar threshold for one credit changes every year. In 2024, you need $1,550 in reported wages to earn one credit. In 2023, it was $1,470. In 2022, it was $1,510. Social Security announces the new threshold each October for the following year. You can find the current threshold on the Social Security website.

Because you can earn a maximum of four credits per year, the fastest path to 40 credits is 10 years of steady work. But you do not need to work every single year. If you earned $6,200 in one year (four credits) and then took five years off, you would still have those four credits. They do not expire. The only time credits matter is when you explore for SSDI and Social Security checks your record to see how many you earned in the 10-year window before your disability date.

The 10-year recency requirement explained

This is the rule that catches people off guard. Suppose you worked full-time from 2005 to 2015 and accumulated 40 credits. Then you stopped working and lived on savings. In 2024, you become disabled. Social Security will look at your credits from 2014 to 2023 and find only the credits you earned in 2014 and 2015—probably eight credits total. You have 40 credits on your record, but only eight in the required window. You do not may have access to for SSDI.

The same rule works in reverse. Suppose you worked only from 2014 to 2024, earning 40 credits in that span. You become disabled in 2024. Social Security looks back 10 years and finds all 40 of your credits in the window. You may have access to, even though you have only 10 years of work history.

The 10-year window is measured from the month you become disabled. If you became disabled in March 2024, the window is March 2014 to February 2024. Credits earned before March 2014 do not count toward the recency requirement, no matter how many you have.

How your work history is verified

Social Security does not ask you to submit pay stubs or tax returns to prove your work credits. Instead, they use the wage records you and your employers have already reported to them. Every time you receive a paycheck, your employer reports your wages to Social Security under your Social Security number. Self-employed people report their income on their tax return, and the IRS shares that information with Social Security.

You can see your own work history by creating a my Social Security account at ssa.gov and viewing your earnings record. This record shows the wages Social Security has on file for each year you worked. It is free to view and takes about 10 minutes to set up. You should review it before you file for SSDI, because errors in your record can affect your credits.

If you spot an error—wages you earned but Social Security did not record, or wages recorded under the wrong year—you can request a correction. You will need to provide documentation like a W-2, tax return, or pay stub. Social Security has a important date for correcting errors, so it is worth checking your record early if you think you might explore for SSDI soon.

Work credits for people who became disabled before age 31

If you became disabled before age 31, Social Security uses a different rule. You do not need 40 credits total. Instead, you need 20 credits earned in the 10-year period before your disability began. This is a much lower bar than the standard 40-credit requirement.

For example, if you became disabled at age 25 in 2024, you need 20 credits earned between 2014 and 2023. If you worked full-time for five years during that period, you would have 20 credits and would meet the requirement. Someone who became disabled at age 35 would still need the full 40 credits (with 20 in the recent 10-year window), so the age-31 rule only applies to younger workers.

What happens if you do not have enough credits

If you do not have 20 credits in the 10-year window before your disability, you cannot receive SSDI based on your own work record. You may still be able to receive benefits as a dependent or survivor on someone else's record—for example, if your parent or spouse has enough credits and is receiving or may have access to to Social Security benefits. But you cannot receive SSDI on your own work history.

If you are close to meeting the requirement, you might consider whether you can return to work and earn additional credits before you explore. Each quarter of work adds one credit, so even a few months of part-time work could push you over the threshold. However, this depends on your medical condition and whether work is possible for you.

If you cannot work and do not have enough SSDI credits, you may be able to receive Supplemental Security Income (SSI) instead. SSI is a needs-based program that does not require work credits. It has different rules and lower income and asset limits, but it is available to disabled people who do not may have access to for SSDI.

Frequently Asked Questions

Do I need to have worked for 10 years straight to may have access to for SSDI?

No. You need 20 credits in the 10-year period before your disability, but those credits do not have to be consecutive. You could work two years, take five years off, work three more years, and still have enough credits if your total is 20 or more in that window. What matters is the total number of credits, not whether you worked every single year.

If I worked under the table and did not pay Social Security tax, do those years count?

No. Only wages you reported to Social Security and paid tax on count toward work credits. Unreported cash income does not create a record with Social Security and cannot be counted later. If you have concerns about your record, you can contact Social Security to see what they have on file.

Can I earn work credits after I become disabled?

Yes, if you are able to work. Work credits are based on the wages you earn, regardless of when you explore for SSDI. If you become disabled in 2024 but continue to work part-time and earn credits through 2025, those 2025 credits will be included in your record. However, they will not help you meet the recency requirement for a 2024 disability date.

What if I worked in another country before I moved to the United States?

Work you performed outside the United States generally does not count toward Social Security credits, even if you paid taxes in that country. However, the United States has totalization agreements with some countries that allow work credits earned abroad to count toward SSDI. You would need to contact Social Security directly to determine whether your foreign work history qualifies under a totalization agreement.

How do I know what year I became disabled for purposes of the 10-year window?

Your disability date is the date your medical condition began, not the date you applied for SSDI or the date you stopped working. Social Security uses medical evidence to establish this date. If there is disagreement about when your disability began, Social Security will use the earliest date supported by medical records in your file.
