Learn How Disability Payments and Social Security Work

Understanding Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI)

The Social Security Administration (SSA) manages two separate programs that provide monthly payments to people with disabilities. These programs work differently, have different rules, and serve different groups of people. Understanding which program might apply to your situation is an important first step in learning about disability payments.

Social Security Disability Insurance (SSDI) is a program for people who have worked and paid Social Security taxes. If you have a work history and become unable to work because of a medical condition that is expected to last at least 12 months or result in death, you may have worked long enough to have SSDI protection. The amount you receive is based on your past earnings record. In 2024, the average SSDI payment is around $1,550 per month, though payments vary based on individual work histories.

Supplemental Security Income (SSI) is different from SSDI. SSI provides payments to people who are disabled, blind, or age 65 or older and have limited income and resources. Unlike SSDI, you do not need a work history to receive SSI. Your total resources cannot exceed $2,000 (or $3,000 if you are married), and you must meet strict income limits. In 2024, the maximum SSI payment is $943 per month for an individual, though some states add additional money to this amount.

Some people can receive both SSDI and SSI at the same time, though this is rare. This happens when your SSDI payment is very low. The two programs can work together to bring your total payment up to the SSI limit.

Practical takeaway: Before exploring either program further, determine whether you have a significant work history. If you do, SSDI may apply to you. If you have little or no work history, or if you worked but do not have enough credits, SSI might be the program to learn more about. You can request a Statement of Earnings from the SSA to see your work record.

Medical Requirements and How Disability Is Defined

Both SSDI and SSI have strict medical rules about what counts as a disability. The Social Security Administration does not consider you disabled just because you have a medical condition or because you cannot work at your previous job. Instead, the SSA uses a specific legal definition: a medical condition that prevents you from doing substantial work and is expected to last at least 12 months or result in death.

"Substantial work" is defined as earning more than a certain amount of money per month. In 2024, substantial work means earning more than $1,550 per month. If you earn $1,550 or less and meet the other disability requirements, you may be considered disabled. This threshold changes each year with inflation.

The SSA evaluates disability using a five-step process. First, they determine whether you are currently working and earning substantial income. If you are, your case typically ends here—you would not be found disabled. Second, they look at whether you have a "severe" medical condition that lasts or is expected to last at least 12 months. Third, they check whether your condition matches one of the SSA's medical listings—these are specific medical conditions the SSA recognizes as automatically severe enough to prevent work. These listings cover conditions such as cancer, heart disease, mental illness, and many others.

Fourth, if your condition does not match a medical listing, the SSA determines what work you can do despite your condition. This includes any type of work, not just the type you previously did. Fifth, they consider your age, education, and work experience to determine if there is any work available in the national economy that you could perform.

Documentation from your doctors is critical. The SSA bases its decisions on medical evidence, including test results, physician notes, treatment records, and specialist opinions. Conditions that are not treated or documented are much harder to prove as disabling.

Practical takeaway: Keep detailed records of all medical treatment, test results, and doctor visits. When you gather information about your condition for the SSA, include reports from all doctors who have treated you. The more thorough your medical documentation, the stronger your case will be.

Work History, Earnings Records, and SSDI Credits

SSDI is based on work history. To potentially receive SSDI, you must have worked long enough and recently enough to have earned enough "Social Security credits." Understanding how these credits work helps you determine whether SSDI might be available to you.

You earn Social Security credits by working and paying Social Security taxes. In 2024, you earn one credit for each $1,730 in covered wages or self-employment income, up to four credits per year. Most people need 40 credits total to be insured for SSDI, meaning they need to have worked approximately 10 years with covered earnings. However, younger people may be able to receive SSDI with fewer credits. For example, a 24-year-old might need only 20 credits—about five years of work.

The SSA also requires that you have worked recently. Generally, you must have earned 20 of your 40 credits in the 10 years before you became disabled. There are some exceptions for people who became disabled before age 31, who may need fewer recent credits.

Your SSDI payment amount is based on your "primary insurance amount" (PIA), which is calculated from your average earnings during your working years. The SSA uses a formula that takes your highest 35 years of earnings (after adjusting for inflation) and calculates an average. If you did not work 35 years, the formula includes zeros for the missing years, which can lower your payment amount. For this reason, people who had interrupted work histories or took time out of the workforce often receive lower SSDI payments.

You can see your complete earnings record by creating an account on ssa.gov and viewing your Social Security Statement. This shows your credited earnings year by year, any gaps in your work history, and an estimate of your potential SSDI payment. Review this carefully for errors, as mistakes on your record can affect your payment amount.

Practical takeaway: Check your earnings record now, even if you are not currently considering SSDI. If you find errors, contact the SSA to correct them. Getting errors fixed now is much easier than correcting them later when you file for benefits.

The Application and Review Process

Understanding the process for filing and what happens after you file helps you know what to expect. The process typically takes several months and involves several stages of review.

You can start the process by contacting your local Social Security office, calling the SSA at 1-800-772-1213, or visiting ssa.gov. You will need to provide basic information, medical records, work history, and details about your disability. The SSA will schedule appointments to gather this information. Many people find it helpful to organize their medical records and write down a summary of their medical condition and how it affects their ability to work before these appointments.

After you submit your information, the SSA sends your case to Disability Determination Services (DDS), an agency in your state that makes the actual disability decision. DDS may request additional medical records from your doctors. This process typically takes 3-6 months. During this time, you can send in additional medical evidence if you have recent treatment or new test results.

DDS will make an initial decision—either approving your case, denying it, or continuing to gather information. If they deny your case, you have the right to request a reconsideration, which sends your case to a different DDS examiner for another full review. About one-third of cases that are initially denied are approved at reconsideration.

If your case is denied again after reconsideration, you can request a hearing before an Administrative Law Judge (ALJ). This is a more formal process where you can present your case in person, with an attorney or representative if you choose. Many people are approved at the hearing stage.

If you disagree with the ALJ decision, you can appeal to the Appeals Council. If that is also denied, you can file a lawsuit in federal court. Each of these levels can take many months.

Practical takeaway: Understand that the initial decision is not final. Many people are denied initially but approved at a later stage. If you receive a denial, consider requesting reconsideration and, if needed, a hearing before an ALJ. Having a
