You cannot receive both SSI and SSDI payments simultaneously, but you may transition from one to the other

Social Security Supplemental Security Income (SSI) and Social Security Disability Insurance (SSDI) are separate programs with different rules, different funding sources, and different payment amounts. The Social Security Administration does not allow you to collect both at the same time. However, your situation may change over time — you might start on one program and move to the other, or you might receive one program's benefits while working under specific rules that let you keep some income.

The key difference is how you became disabled and what work history you have. SSDI is based on your own work record or your parent's work record if you became disabled before age 22. SSI is a needs-based program for people with low income and few resources, regardless of work history. Understanding which program you are on now, and what happens if your circumstances change, prevents you from accidentally losing benefits you are may have access to to.

Key Takeaways

  • You cannot collect SSI and SSDI payments in the same month, but you can transition from one program to the other as your work history or income changes.
  • If you have a work history and your condition is severe enough, SSDI typically pays more than SSI and has higher income and resource limits.
  • Some people start on SSI when they have no work history, then move to SSDI later once they have worked enough quarters to may have access to.
  • If you are on SSI and earn income from work, you can keep some of that income without losing all your SSI benefits through work incentive rules.
  • The Social Security Administration will tell you which program you are on and what your payment amount is; contact them directly if you are unsure.

Why you cannot receive both programs at once

SSI and SSDI serve different purposes in the Social Security system. SSDI is an insurance program — you or your family members paid into it through payroll taxes, and you are drawing on that insurance when you become disabled. SSI is a welfare program funded by general tax revenue, designed to help people with disabilities who have little or no income and very few assets.

Because SSI is means-tested (based on your income and resources), Social Security does not allow you to stack it on top of SSDI. If you are receiving SSDI, your income is already above the SSI threshold, so you would not meet SSI's resource and income limits anyway. The Social Security Administration's computer system prevents dual payments — if you are approved for one program, the other automatically closes or never opens.

Moving from SSI to SSDI when you gain work history

Many people begin on SSI because they have a disability but no substantial work history. If you then work and accumulate enough work credits (also called quarters), you may become may be able to access for SSDI instead. You need 40 work credits total, with at least 20 earned in the 10 years before you became disabled. Each quarter of 2024 requires $1,550 in earnings to count as one credit; this amount changes yearly.

When you reach the threshold, you do not need to do anything — Social Security's system will detect that you now may have access to for SSDI. The agency will contact you to explain the change. Your SSI will stop, and your SSDI will begin in the same month. SSDI typically pays more than SSI because it is based on your actual earnings record rather than a flat federal rate. You will also gain access to higher income and resource limits, and your family members may be able to collect benefits on your record.

This transition is one reason why work incentive programs exist. Social Security wants to encourage people on SSI to work without fear of losing benefits entirely. Programs like Impairment Related Work Expenses (IRWE) and Plans to Achieve Self-Support (PASS) let you deduct certain costs from your income, so you can work more hours and build your record faster without losing SSI in the meantime.

Moving from SSDI to SSI if your work record does not extend

This transition is less common but can happen. If you are on SSDI and your benefits end — for example, because you reached full retirement age and your benefits converted to retirement benefits, or because a medical review found you no longer disabled — you might then turn to SSI if you have low income and few resources.

You would need to contact Social Security and request an SSI process. The agency will evaluate your income, resources, and living situation under SSI rules. This is a separate process from your SSDI case, so there is no automatic transition. You must meet SSI's resource limit (currently $2,000 for an individual, though this varies by state for some programs) and income limits to be approved.

How work incentives let you earn money while on SSI

If you are on SSI and want to work, you do not have to choose between your job and your benefits. Social Security has built-in work incentives that let you keep some of your earnings without losing all your SSI payment. The most common is the Student Earned Income Exclusion, which excludes up to $2,170 per month in earnings if you are under 22 and a student (2024 limit; this changes yearly). For non-students, the General Earned Income Exclusion excludes the first $65 of monthly earnings, plus half of the remainder.

There are also programs like PASS and IRWE that let you set aside income or deduct work-related costs. With PASS, you can exclude income you are saving toward a work goal — like paying for training or a business startup. With IRWE, you can deduct costs directly related to your disability that let you work, such as attendant care, transportation, or medical devices. These programs are complex, and Social Security has work incentive planners who can walk through your specific situation for free.

What to do if you are unsure which program you are on

Your Social Security statement or award letter will clearly say whether you are receiving SSI or SSDI. If you have lost that document, you can create a my Social Security account at ssa.gov and log in to see your benefit type and current payment amount. You can also call Social Security's main line at 1-800-772-1213 (TTY 1-800-325-0778) and speak to a representative who can tell you which program you are on and answer questions about your specific case.

If you are thinking about working or your income situation has changed, mention that when you call. Social Security can explain which work incentives explore to you and whether your situation might lead to a program change. The agency also has a Ticket to Work program that lets you test your ability to work without when ready losing benefits — you have a grace period to see if employment is sustainable before your case is reviewed.

Frequently Asked Questions

If I am on SSI and start working, will I automatically move to SSDI?

Not automatically. You will move to SSDI only if you earn enough work credits (40 total, with 20 in the past 10 years). Work incentives like the General Earned Income Exclusion let you keep working on SSI while you build your record. Once you hit the credit threshold, Social Security will notify you of the change.

Can I collect SSDI from my parent and also get SSI?

No. If you are receiving SSDI as an adult child on your parent's record, you cannot also receive SSI. However, if your parent's SSDI ends (for example, if your parent passes away), you may then turn to SSI if you meet its income and resource limits.

What happens to my benefits if I get married?

SSDI and marriage do not affect each other — your spouse's income does not count against your SSDI. SSI is different: your spouse's income and resources count toward your SSI limits. If you are on SSI and marry someone with income, your SSI payment will likely decrease or stop. Contact Social Security before you marry to understand the impact.

If I am denied SSDI, can I when ready explore for SSI instead?

You can request SSI, but it is a separate process with different rules. A SSDI denial does not automatically mean SSI will deny you — SSI looks at your current income and resources, not your work history. You would need to submit an SSI process and meet those program's requirements.

Can I work part-time on SSDI without losing my benefits?

SSDI has a trial work period that lets you test your ability to work without losing benefits for nine months. After that, you enter an extended may be able to access period where you can work and earn above the limit for a few months before benefits stop. The rules are complex and depend on how much you earn, so contact Social Security before you start working.
