How to Switch Between SSDI and SSI, or Change Which Program You're On

What "switch disability" means and when you might need to do it

Switching disability usually means moving from one Social Security disability program to another, or changing how you receive benefits within the same program. The two main programs are SSDI (Social Security Disability Insurance, based on your work history) and SSI (Supplemental Security Income, based on financial need). You might also switch between different types of benefits — for example, from your own disability benefit to a family member's benefit based on their work record, or from disability to retirement when you reach full retirement age.

The process and timeline depend on which direction you are moving and whether Social Security initiates the switch or you do. Some switches happen automatically; others require you to contact Social Security and provide new information. Understanding which situation applies to you prevents delays and unexpected changes to your monthly payment.

Key Takeaways

You cannot hold both SSDI and SSI at the same time, but you can move from one to the other if your circumstances change.
If you turn 66 and reach full retirement age while on SSDI, Social Security automatically converts your benefit to retirement — no action needed on your part.
If you inherit a higher benefit through a family member's work record, you must contact Social Security to request the switch; they do not do it automatically.
Switching from SSI to SSDI happens when you accumulate enough work credits, and Social Security will notify you when the change takes effect.
Plan ahead if you expect a switch: contact your local Social Security office at least 30 days before the change to confirm the timing and what documents you need.

Automatic switches: what happens without you asking

Social Security moves you automatically in a few situations. The most common is conversion from SSDI to retirement benefits when you reach your full retirement age (between 66 and 67, depending on your birth year). Your monthly payment stays the same, but the program name changes and the rules that govern your benefit change slightly — for example, you can now earn unlimited work income without losing benefits.

Another automatic switch occurs if you are on SSI and your work credits accumulate enough to may have access to for SSDI. Social Security tracks your earnings record and will send you a notice when you become may have access to to SSDI. Your SSI stops and SSDI begins, usually in the same month. The payment amount may be higher, lower, or the same depending on your earnings history.

You will receive a notice in the mail before any automatic switch takes effect. Read it carefully — it will tell you the new program name, the new payment amount, and the effective date. If the notice contains an error or you do not understand it, contact your local Social Security office before the switch date to ask questions.

Requesting a switch yourself: SSDI to SSI or SSI to SSDI

If your circumstances change and you want to move from one program to another, you must contact Social Security and request the switch. This happens when you lose SSDI may be able to access (for example, your medical condition improves and you are no longer disabled) but you still need income support and meet SSI's financial limits. It also happens when you want to move from SSI to SSDI because you have now earned enough work credits.

Start by calling Social Security at 1-800-772-1213 (TTY 1-800-325-0778) or visiting your local Social Security office in person. Tell them you want to switch programs and explain why your situation has changed. They will ask you questions about your current income, resources, living situation, and work history. Bring documents that support your request: recent pay stubs, bank statements, proof of living expenses, and any medical records if your health status has changed.

Social Security will review your request and send you a written decision. The process typically takes 30 to 60 days. During that time, continue receiving your current benefit — do not assume the switch has happened until you receive official notice. Once approved, your new benefit begins the following month, and your old benefit ends.

Switching to a family member's benefit: deemed and undeeming

If a family member — a parent, spouse, or adult child — is receiving SSDI or retirement benefits, you may be may have access to to a benefit based on their work record instead of your own. This is called a family benefit or auxiliary benefit. If you are already on your own SSDI and your family member's benefit would be higher, you can request to switch to their benefit.

Contact Social Security and ask about switching to a family member's benefit. You will need to provide proof of your relationship (birth certificate, marriage certificate, or adoption papers) and the family member's Social Security number. Social Security will calculate both benefits and pay you whichever is higher. This is not a separate payment — you receive one monthly check based on the higher amount.

Be aware of a rule called deemed filing. If you file for a family benefit before your full retirement age, Social Security may automatically file you for your own benefit at the same time. This can affect the amount you receive. Ask Social Security whether deemed filing applies to you before you request the switch.

What happens to your payment during a switch

Your monthly payment amount may change when you switch programs. SSDI and SSI use different formulas: SSDI is based on your lifetime earnings, while SSI is based on financial need and has a federal maximum (which varies by state because some states add money to the federal amount). Switching from SSDI to SSI usually means a lower payment, while switching from SSI to SSDI may mean a higher one.

Social Security will tell you the new payment amount in the notice they send you. If the amount decreases, ask whether you are may have access to to any other benefits or programs that might help — for example, Medicaid, food information, or housing support. If the amount increases, the higher payment begins the month after the switch is approved.

There is usually a one-month gap between when your old benefit stops and your new benefit starts. Plan your budget for that month. If you have questions about the payment timing, call Social Security before the switch date.

Switching back: reversing a decision or changing your mind

If you switch programs and then want to switch back, you can request a reversal within a limited time. If Social Security made an error in processing your switch, you can ask them to correct it at any time. If you requested the switch yourself and changed your mind, you have 12 months to ask for a reversal — but only if you have not yet received a payment under the new program.

Once you have received even one payment under the new program, reversing the switch becomes much harder. You would need to show that you made the request based on incorrect information or that your circumstances have changed again. Contact your local Social Security office as soon as you realize you want to reverse the switch.

If Social Security made an error — for example, they switched you to a lower benefit when you should have stayed on a higher one — you can file a complaint and request a correction. Ask for a detailed explanation of how they calculated your benefit, and if you disagree, you can request a reconsideration or appeal.

Documents you need before you switch

The documents required depend on which switch you are making, but most switches require proof of identity, proof of citizenship or legal residency, and documentation of your current situation. Here is what to gather before you contact Social Security:

Original or certified birth certificate (or passport for non-citizens)
Current photo ID (driver's license, state ID, or passport)
Social Security card (or a record of your number)
Recent pay stubs or proof of current income
Bank statements showing your current savings and resources
Proof of living situation (lease, mortgage statement, or utility bill)
Medical records if your health status has changed
Proof of relationship if switching to a family member's benefit (marriage certificate, birth certificate, adoption papers)

You do not need to bring everything at once. Social Security will tell you which documents they need for your specific switch. If you do not have an original document, ask whether a certified copy is acceptable.

Timeline: how long a switch takes

An automatic switch (SSDI to retirement, or SSI to SSDI when you earn enough credits) happens on the date Social Security determines you are may have access to to the new benefit. You will receive notice 30 to 60 days before the switch. Plan for a one-month gap between when your old benefit stops and your new benefit starts.

A switch you request (moving from SSDI to SSI, or from SSI to SSDI) typically takes 30 to 60 days from the date you submit your request. Social Security will send you a written decision. If they deny your request, the notice will explain why and tell you how to appeal.

If you are switching to a family member's benefit, the timeline depends on whether Social Security has to verify your relationship. If you have already provided proof of relationship in the past, the switch may be faster. If this is the first time you are claiming a family benefit, allow 60 to 90 days.

Frequently Asked Questions

Can I be on both SSDI and SSI at the same time?

No. Social Security will not pay you both benefits simultaneously. If you are may have access to to both, they pay you whichever is higher. If you are on one program and become may have access to to the other, Social Security switches you to the higher benefit automatically or after you request it.

What happens to my Medicare or Medicaid when I switch?

If you switch from SSDI to SSI, you may lose Medicare and gain Medicaid instead, depending on your state. If you switch from SSI to SSDI, you may lose Medicaid and gain Medicare. Contact your state Medicaid office and Medicare at 1-800-633-4227 to confirm your coverage before and after the switch.

Do I have to switch if my circumstances change?

Contact Social Security to discuss your options.

What if Social Security made a mistake when they switched my benefit?

Ask Social Security for a detailed explanation of how they calculated your new benefit amount. If you disagree, you can request a reconsideration within 60 days of the notice. If Social Security switched you to a lower benefit by error, ask them to correct it and pay you the difference retroactively.

Can I switch programs if I am appealing a denial?

If you are appealing a denial of one program, you can still request to switch to another program while the appeal is pending. The two processes happen separately. Tell Social Security about both the appeal and your request to switch so they do not process them in the wrong order.
