What Disability Allowance Means Under Social Security

Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI) are the two federal programs that pay monthly cash to people with disabilities. Neither is called "disability allowance," but both are often referred to that way in conversation. The difference matters: SSDI is based on your own work history and the taxes you paid into Social Security, while SSI is a needs-based program for people with very low income and resources, regardless of work history.

Whether you meet the requirements for either program depends on three separate things: your medical condition, your work history (for SSDI only), and your income and assets (for SSI only). This article walks through what each program requires and how to figure out which one might explore to you.

Key Takeaways

  • SSDI requires that you have worked long enough and recently enough to have earned sufficient work credits, while SSI has no work history requirement but strict income and asset limits.
  • Both programs require that your medical condition prevent you from working for at least 12 months or result in death, and Social Security will use its own doctors to evaluate your condition.
  • You can meet the work credit requirement for SSDI even if you have not worked in years, as long as you earned enough credits before you stopped working.
  • If you do not have enough work credits for SSDI, you may still meet the requirements for SSI if your income and resources fall below the monthly limits.
  • The Social Security Administration makes the final information about whether you meet the requirements; this guide explains what those requirements are, not whether you will be approved.

The Medical Requirement Both Programs Share

Both SSDI and SSI require the same medical standard: your condition must prevent you from doing substantial work for at least 12 consecutive months, or it must be expected to result in death. "Substantial work" means earning more than a set monthly amount—in 2024, that amount is $1,550 per month, though it changes each year. If you earn more than that while receiving benefits, Social Security will review your case.

Social Security does not take your word for your condition. The agency has its own doctors and medical consultants who review your medical records, test results, and treatment history. They may also order a consultative exam—a medical evaluation paid for by Social Security—to gather information they need. You do not choose the doctor; Social Security does. Your own doctors' opinions matter, but Social Security weighs all the evidence and makes its own information.

The condition does not have to be physical. Mental health conditions, intellectual disabilities, learning disorders, and neurological conditions all can meet the medical requirement if they are severe enough and well-documented. What matters is whether the condition, in combination with your age and work history, prevents you from working.

Work Credits: The SSDI Requirement You May Already Have

SSDI requires work credits, which you earn by working and paying Social Security taxes. You earn one credit for each $1,640 of wages in 2024 (this amount changes yearly). You can earn a maximum of four credits per year, so you need to work roughly three months per year to earn four credits. The exact timing does not matter—you could earn all four credits in one month if you earned enough, or spread them across the year.

Most people need 40 work credits total to receive SSDI, and at least 20 of those credits must have been earned in the 10 years before you became disabled. However, if you became disabled before age 24, you may need fewer credits. If you became disabled between ages 24 and 31, you generally need credits for half the time between age 21 and the time you became disabled. If you were disabled after 31, the 40-credit rule applies.

You can check how many credits you have earned by creating an account on ssa.gov and viewing your Social Security Statement, or by calling Social Security at 1-800-772-1213 and asking for a work history printout. The statement shows your earnings year by year and how many credits you have earned. If you do not have enough credits, you do not meet the SSDI requirement, but you may still meet the requirements for SSI.

Income and Asset Limits for SSI

SSI is for people with disabilities who have very limited income and resources. In 2024, the monthly income limit for a single person is $943 (this varies by state and changes yearly). "Income" includes wages, Social Security benefits, pensions, and most other money coming in, though some types of income are not counted—for example, the first $65 per month of wages and half of wages above that are excluded.

SSI also has a resource limit: you can own no more than $2,000 in countable resources as a single person, or $3,000 as a couple. Resources include cash, bank accounts, stocks, and property you own—but not your home, your car (if you use it for work or transportation), or certain other items. If you are over the resource limit, you do not meet the SSI requirement, even if your income is low enough.

Because SSI limits are strict, many people who do not have enough work credits for SSDI also do not meet the SSI income and resource requirements. If that is your situation, you would not meet the requirements for either program based on current rules. However, if your circumstances change—your income drops, you spend down resources, or you earn more work credits—your situation may change.

Age and How It Affects Your Requirements

Your age changes how Social Security evaluates your case, even though the medical requirement stays the same. If you are under 50, Social Security assumes you have more ability to adjust to different types of work, so the medical evidence must show you cannot do any substantial work. If you are 50 or older, Social Security can consider your age, education, and work history when deciding whether you can work, and may find you disabled even if you could theoretically do some work.

If you are 55 or older and have a history of unskilled work, Social Security may find you disabled based on less severe medical evidence than it would for a younger person. This does not mean age alone makes you disabled—the medical condition still has to prevent work—but age is one factor Social Security weighs.

How to Find Out Your Work Credit Status

The fastest way to learn how many work credits you have is to create a my Social Security account at ssa.gov. Once you log in, you can view your Social Security Statement, which lists your earnings history and the number of credits you earned each year. The statement also shows an estimate of what your SSDI benefit would be if you met the medical requirement.

If you do not want to create an online account, you can call Social Security at 1-800-772-1213 and ask for a work history printout. You will need to provide your Social Security number and date of birth. Social Security will mail the printout to you, which usually takes one to two weeks. You can also visit your local Social Security office in person, though wait times vary.

Once you have your work history, count backward from the year you became disabled (or the year you plan to file) to see whether you have 20 credits in the past 10 years. If you do, and you have 40 credits total, you meet the work credit requirement for SSDI. If you do not, check whether your income and resources fall within SSI limits.

What Happens After You Know Your Requirements

Learning that you meet the requirements for SSDI or SSI does not mean you will receive benefits. It means you are may be able to access to file. Social Security will still evaluate your medical condition using its own doctors and standards. The agency receives thousands of applications each month and approves roughly 30 percent of initial applications; the rest are denied or require an appeal.

If you decide to file, you will need to submit medical records, work history documentation, and other evidence. The process takes several months, and many people are denied on their first process and must appeal. Understanding whether you meet the basic requirements—work credits for SSDI, or income and resource limits for SSI—is the first step, but it is not the final step.

Frequently Asked Questions

Can I get SSDI if I have not worked in 10 years?

It depends on when you stopped working. If you earned 20 work credits in the 10 years before you became disabled, you meet the recency requirement. If you stopped working 10 years ago but earned those 20 credits before you stopped, you still meet the requirement. However, if you became disabled more than 10 years after you stopped working, you would not meet the recency requirement for SSDI.

Does my spouse's income count against me for SSI?

Yes. For SSI, Social Security counts your spouse's income and resources as partially available to you, even if your spouse does not want to share it. This is called "deeming." If your spouse's income is high, it may push you over the SSI limit even if your own income is low. SSDI has no income limit, so your spouse's income does not affect your SSDI benefits.

What if I have a criminal record or owe child support?

A criminal record does not disqualify you from SSDI or SSI based on the requirements described here. However, if you are fleeing prosecution or a felony conviction, you may be ineligible. If you owe child support, Social Security can withhold part of your benefits to pay it. Neither situation prevents you from meeting the basic requirements, but both can affect your benefits once approved.

Can I work part-time and still meet the SSDI requirement?

Yes. The requirement is that your condition prevents you from doing substantial work—earning more than $1,550 per month in 2024. If you work part-time and earn less than that, you can still receive SSDI. However, Social Security will review your case to make sure your work activity is consistent with your medical condition and your claim that you cannot work.

If I am denied, can I reapply later?

Yes, but the timing matters. If your condition worsens or you earn more work credits, your situation may change and a new process might succeed. However, if you reapply within 12 months of a denial without a significant change in your condition or work history, Social Security will likely deny you again. If you are denied, you have the right to appeal instead of reapplying, and appeal is usually the faster route.
