TL;DR
Apply for SSDI online at ssa.gov in about 30 to 90 minutes, or call 1-800-772-1213 to apply by phone. SSI requires a personal interview at your local Social Security office or by phone. Gather your medical records, work history, and personal documents before you start. Most initial decisions take 6 to 7 months, and about two-thirds get denied the first time.
What are SSDI and SSI, and which one should you apply for?
Social Security runs two separate disability programs with different money rules and the same medical rules. Pick the wrong one and you burn weeks. So know which door you're walking through before you fill out a single form.
SSI (Supplemental Security Income) is needs-based. It pays people who are disabled and have very little income and few assets, roughly $2,000 in countable resources for an individual as of 2024. You don't need any work history to qualify. [1]
SSDI (Social Security Disability Insurance) is an earned benefit. It pays people who are disabled and have built up enough work credits by paying Social Security taxes. In 2024, you generally need 40 credits, 20 of them earned in the last 10 years, though younger workers need fewer. [2]
Some people qualify for both at once. SSA calls that "concurrent." The medical test is identical for both programs. The only difference is the financial side.
Not sure where you land? SSA's Benefit Eligibility Screening Tool (BEST) at ssa.gov gives you a rough answer in a few minutes before you commit to a full application. Treat it as a sanity check, not a promise.
For a broader look at how the programs fit together, see disability benefits and social security disability.
What documents do you need before you apply?
Gathering your documents first is the biggest time-saver in this whole process. The online application times out after 25 minutes of inactivity, and digging through a drawer for your Social Security number mid-session is a real way to lose your place.
Here's what SSA asks for. Not every item fits everyone, so pull together whatever matches your situation.
Personal identity documents
- Social Security number (yours, plus your spouse's and any minor children's if you're applying for SSI)
- Birth certificate or proof of age
- Proof of U.S. citizenship or lawful immigration status
- Military discharge papers (Form DD-214) if you served [3]
Medical records
- Names, addresses, and phone numbers of every doctor, hospital, and clinic that treated you
- Dates of treatment
- Names of all your prescription medications and the doctors who prescribe them
- Any medical records you already have in hand (you can submit these yourself; SSA will also request records directly)
Work and financial history
- Your most recent W-2, or your most recent federal tax return if you're self-employed
- A list of jobs you've held in the last 15 years and the physical and mental demands of each
- Bank account information for direct deposit
- For SSI: proof of current income (pay stubs, pension letters), bank statements, property records, vehicle titles
SSA publishes the full checklist in its "What You Need to Apply" guide at ssa.gov. [3] Print it or bookmark it before you start.
One section people always underestimate is the work history. SSA uses it to decide whether you can still do your old job or any other job in the national economy. Be specific about how much you lifted, how long you stood, whether you supervised anyone, whether you dealt with the public. Vague answers hurt your claim.
How do I apply for disability benefits online?
Online is the fastest way to file for SSDI. You can apply at ssa.gov/applyfordisability at any hour, save your progress and come back later, and get an instant confirmation number when you submit. [4]
Here's the actual sequence:
1. Go to ssa.gov/applyfordisability and start the disability application. 2. Create a free my Social Security account if you don't have one, or log in. Setup takes about 5 minutes. 3. Choose disability benefits and confirm you understand this is the SSDI application. 4. Work through the sections: personal information, work history, medical conditions, and medical sources. 5. Review everything before you submit. SSA says incomplete applications are the leading cause of processing delays. 6. Submit, then write down your confirmation number. SSA mails you an acknowledgment letter after.
The online application usually takes 30 to 90 minutes, depending on how complicated your work history is. If you have to stop, save your progress. The system holds unfinished applications for several days.
One catch: the online application is SSDI only. If you're applying for SSI, or for both, you'll need to call SSA or go in person. A common move is to start the SSDI part online and then call to add the SSI piece. That's a legitimate strategy.
Want to organize your information before you log in to SSA's portal? DisabilityFiled's guided intake tool walks you through the same questions in plain language and builds a claim summary you can keep open as you fill out the official form.
For a focused walkthrough of the SSDI application, see apply for social security disability.
Can you apply for disability benefits by phone or in person instead?
Yes, and for SSI it's often required. Call SSA at 1-800-772-1213, Monday through Friday, 8 a.m. to 7 p.m. local time. A representative will take your information over the phone or set up a telephone interview for later. [4]
Wait times run long, especially early in the week and early in the month. Calling Wednesday or Thursday morning tends to be faster.
To apply in person, find your nearest Social Security office through the office locator at ssa.gov. Bring your documents. Appointments are preferred, and walk-ins are accepted, but the wait varies a lot by office.
For SSI specifically, SSA requires a personal interview, by phone or in person, before it can finish your application. You can usually kick things off with a phone call and then have the formal interview scheduled.
People who are older, uneasy with computers, or in a complicated living situation (living in a care facility, receiving other government benefits) often find the in-person route easier. A claims representative can catch mistakes on the spot instead of three months later.
What happens after you submit the application?
Your case moves through a set pipeline after you file. Knowing the stages keeps you from panicking when months go by with no word.
Step 1: SSA reviews your application (weeks 1 to 4) SSA's processing center checks that your application is complete and that you meet the non-medical basics: age, work credits for SSDI, or income and resource limits for SSI.
Step 2: Your case goes to Disability Determination Services (weeks 4 to 26 and beyond) DDS is a state agency that makes the actual medical decision on SSA's behalf. A DDS examiner reviews your records, usually with a medical consultant. If records are missing, DDS requests them directly from your providers. Slow providers are the single biggest cause of delays. [5]
Step 3: SSA schedules a consultative exam if needed If your own records don't give DDS enough to decide, they'll send you to a doctor they hire for a consultative exam. Go to it. Skipping it is one of the fastest ways to get denied.
Step 4: Decision DDS sends its recommendation to SSA, and SSA mails you a written decision. SSA's reported average processing time for initial claims was 7.4 months in fiscal year 2023. [6]
About 67% of initial SSDI applications get denied. [6] That is not a reason to quit. It's a reason to understand that the appeals system exists and that it works. If you're denied, you have 60 days plus a 5-day mail grace period to file a Request for Reconsideration.

How does SSA decide if you're disabled?
SSA runs every claim through a five-step sequential evaluation set out in 20 C.F.R. § 404.1520. SSDI and SSI use the same five steps. [7]
Step 1: Are you working above the substantial gainful activity level? In 2024, SGA is $1,550 a month for non-blind applicants and $2,590 for blind applicants. Earn more than that from work and SSA stops right here and denies the claim.
Step 2: Is your condition "severe"? Your impairment has to significantly limit your ability to do basic work activities. This is a low bar, but SSA does deny at this step when the medical evidence is thin.
Step 3: Does your condition meet or equal a Blue Book listing? SSA's Blue Book (the Listing of Impairments) spells out the medical criteria for dozens of conditions. Match a listing exactly and you're approved right here, with no work-capacity analysis. [8]
Step 4: Can you do your past work? If you don't meet a listing, SSA figures out your Residual Functional Capacity (what you can still do physically and mentally) and asks whether you could go back to any job you held in the last 15 years.
Step 5: Can you do any other work? If you can't do past work, SSA looks at whether any jobs exist in the national economy that you could still do given your RFC, age, education, and experience. If none do, you're approved.
Most approvals happen at Step 3 or Step 5. Medical evidence aimed at those two steps is where your effort pays off most.
What medical evidence actually wins disability claims?
The file SSA reviews is only as strong as the records your doctors produce. Here's the part that catches people off guard: SSA does not automatically pull your records. You list your providers, DDS requests the records, and providers sometimes take weeks or send incomplete notes.
You can submit records yourself, and you should. Upload them through your my Social Security account, mail them, or drop them at your local office. The more complete your file, the less likely SSA is to send you to a stranger who spends 20 minutes with you at a consultative exam.
What makes a record useful to SSA:
- Specific functional limits ("patient cannot stand more than 15 minutes" beats "patient has back pain")
- Consistent treatment over time
- Objective findings: imaging reports, lab values, pulmonary function tests, mental status exams
- A treating source opinion letter where your doctor states plainly what you can and can't do in work terms
A treating source opinion stopped being automatically controlling after SSA's 2017 rule change. [9] But a well-documented opinion from a doctor who has treated you for years still carries real weight in practice.
SSA's Blue Book lists the exact medical criteria for each condition. [8] Read the listing for your condition before your next appointment so you know what objective evidence SSA wants your doctor to write down.

How long does the disability application process take?
The honest answer is longer than almost anyone expects.
| Stage | Typical timeframe |
|---|---|
| Initial application to first decision | 3 to 7 months |
| Reconsideration (if denied) | 3 to 5 months |
| ALJ hearing (if denied at reconsideration) | 12 to 24 months |
| Appeals Council review (if needed) | 6 to 18 months |
| Federal court (rare) | 1 to 3 years |
SSA's own fiscal year 2023 data show an average initial processing time of 7.4 months and an average wait for an ALJ hearing of about 14 months. [6] Those averages hide wide swings by state and hearing office.
Some people get approved fast. If your condition is on SSA's Compassionate Allowances list (over 200 conditions that are obviously severe, like ALS or certain cancers), SSA flags your case for fast-track handling, sometimes within weeks. [10]
If your condition is terminal or your health is falling apart quickly, ask SSA about terminal illness (TERI) flagging or Dire Need status. Neither is automatic, but both can speed up review.
Back pay, if you're approved, runs to your established onset date, the date SSA decides your disability began. SSDI has a five-month waiting period before benefits start, so the earliest SSDI back pay covers is the sixth month after onset. SSI back pay starts from the month after you applied. [1]
What are common mistakes that get disability applications denied?
SSA denies about two-thirds of initial applications. Some of those denials are unavoidable given the evidence. A real chunk of them come from mistakes you can prevent.
Not treating regularly. Long gaps in your medical records tell SSA your condition isn't as bad as you say. If you stopped seeing a doctor because you couldn't afford it, say so, in writing, on your application.
Overstating or understating your symptoms. Exaggerating backfires because SSA cross-checks your words against your records. Understating hurts just as much, and plenty of people do it out of pride or habit. Describe your worst days, not your best ones.
Missing the consultative exam. If SSA schedules a CE and you don't show up or reschedule, you'll almost certainly be denied for failure to cooperate.
Listing the wrong onset date. People tend to write the date they stopped working. Your onset date should be when the medical records show you became disabled. Those are often different dates, and the gap changes your back pay.
Applying for only one program when you might qualify for both. If your SSDI benefit would be small (under about $600 a month), SSI might pay more or top it off. Ask SSA to screen you for both.
Submitting an incomplete application. SSA either returns incomplete applications or denies them. Fill in every field, even the ones that feel unrelated to your condition.
Worried about these? DisabilityFiled's guided intake process flags common gaps before you submit to SSA, so you get a chance to fix them first.
Can veterans apply for VA disability and Social Security disability at the same time?
Yes. VA disability and Social Security disability are separate programs with separate standards. A VA rating does not automatically qualify you for SSDI or SSI, and SSA is not bound by the VA's number. Under SSR 06-03p, though, SSA must give VA ratings "substantial weight" in its analysis. [11]
Applying for both at once is usually the right move if you meet the basic eligibility rules for each. They aren't mutually exclusive, and they aren't offset dollar-for-dollar against each other. (SSI does have income rules, so VA compensation can reduce an SSI payment.)
For what the VA program covers on its own, see va disability benefits for veterans and disabled veteran benefits. Veterans rated 100% should also check 100 disabled veteran benefits for the full picture of federal and state benefits.
If you have a service-connected condition that shows up in SSA's Blue Book or on the Compassionate Allowances list, flag it clearly in your application. It speeds things up.
What should you do if your disability application is denied?
A denial letter does not end your claim. It moves you to the next step, and the next step is where a lot of people win.
There are four levels of appeal: 1. Reconsideration: a different DDS examiner reviews the file, including any new evidence you add 2. Administrative Law Judge (ALJ) hearing: a hearing before an SSA judge where you testify and can bring a representative 3. Appeals Council: review by SSA's internal appellate body 4. Federal district court
The ALJ hearing is where the odds shift hardest in claimants' favor. SSA's data show hearing approval rates historically running 45% to 55%, against roughly 13% to 15% at reconsideration. [6]
Representation matters most here. Represented claimants win at hearings at meaningfully higher rates than unrepresented ones, per SSA's own research. Disability attorneys and non-attorney representatives work on contingency: 25% of your back pay up to a $7,200 cap (the 2024 figure, adjusted periodically by SSA). [12] Lose, and you owe nothing.
The 60-day appeal deadline is strict. Miss it and you generally start over with a brand-new application. File the appeal first, then gather new evidence.
For help finding representation, see long term disability lawyer.
How much will you get paid if your disability claim is approved?
SSDI pays based on your lifetime average indexed monthly earnings. The formula is a mess, but SSA runs it for you. In 2024, the average SSDI payment is about $1,537 a month, and the maximum for someone who earned near the wage cap throughout their career is $3,822 a month. [13]
SSI pays a flat federal benefit rate: $943 a month for an individual and $1,415 for a couple in 2024. Some states add a supplement on top. [1]
SSDI recipients become eligible for Medicare after a 24-month waiting period from their first month of entitlement. SSI recipients get Medicaid right away in most states.
If your SSDI check will be small (roughly under $600 a month), run the SSI numbers. If your countable income and resources are low enough, SSI can top off your SSDI or beat it outright.
For a full breakdown of amounts and how they're figured, see how much will I receive from social security disability and the social security disability benefits pay chart. Timing details are at social security disability benefits payment schedule.
One tax note: SSDI benefits can be taxable at the federal level if your combined income tops $25,000 (single) or $32,000 (married filing jointly). SSI is never federally taxable. [14] More at are disability benefits taxable.
Frequently asked questions
How do I apply for disability benefits online?
Go to ssa.gov/applyfordisability, log in or create a free my Social Security account, and complete the online SSDI application. It takes 30 to 90 minutes and you can save your progress. SSI cannot be finished online. You'll need to call 1-800-772-1213 or visit a local SSA office for that part. You get a confirmation number when you submit.
Can I apply for both SSDI and SSI at the same time?
Yes. If you meet SSDI's work-credit rule and also have limited income and assets, you may qualify for both concurrently. Tell SSA to screen you for both when you apply. The medical standard is identical; the difference is financial. Concurrent claimants usually get the higher of the two payments, plus an SSI supplement if SSDI alone falls short of the SSI federal benefit rate.
How long does it take to get approved for disability benefits?
Initial decisions average about 6 to 7 months nationally, based on SSA's fiscal year 2023 data. If you're denied and appeal to an ALJ hearing, add another 12 to 24 months. Total time from application to final approval can run 2 to 3 years for cases that go to hearing. Compassionate Allowances conditions and terminal illness cases can be approved in weeks.
What is the difference between SSDI and SSI?
SSDI is based on your work history and Social Security tax contributions. SSI is needs-based and open to you regardless of work history, but you must have very limited income and assets (under $2,000 for an individual in 2024). Both use the same five-step medical evaluation. SSDI leads to Medicare after 24 months; SSI usually comes with Medicaid right away.
What conditions automatically qualify you for disability?
No condition guarantees automatic approval, but conditions on SSA's Compassionate Allowances list (over 200 diagnoses including ALS, early-onset Alzheimer's, and certain cancers) trigger fast-track processing. Conditions in SSA's Blue Book Listing of Impairments that meet the specific medical criteria there result in approval at Step 3 of the five-step evaluation, with no further work-capacity analysis.
What happens if I miss the 60-day appeal deadline after a denial?
Missing the deadline almost always means starting over with a brand-new application, which restarts the clock and can cost you back pay tied to your original filing date. SSA allows late appeals if you show "good cause" (a serious illness, a death in the family), but good cause is granted narrowly. File a protective appeal right away even if you're still gathering new evidence.
Do I need a lawyer to apply for Social Security disability?
Not for the initial application. Most people file on their own. Representation becomes far more valuable at the ALJ hearing stage, where represented claimants win at higher rates. Disability attorneys and representatives work on contingency at a capped fee (25% of back pay, maximum $7,200 in 2024). You pay nothing if you don't win.
Can I apply for disability benefits if I'm still working?
You can apply, but if you earn more than $1,550 a month (the 2024 SGA threshold for non-blind applicants), SSA denies the claim at Step 1 without ever reviewing your medical evidence. If you earn below SGA, SSA moves on to the medical review. Stopping work before applying isn't required, but working above SGA makes approval essentially impossible.
How do I check the status of my disability application?
Log in to your my Social Security account at ssa.gov to see status updates online. You can also call SSA at 1-800-772-1213. If your case is at the DDS stage, you can sometimes contact your state DDS office directly. SSA mails status letters at key decision points, so keep your address current in your my Social Security account.
What is back pay for disability benefits and how does it work?
If SSA approves your claim, it pays benefits back to your established onset date, the date your disability began, or your application date, whichever is later in most cases. For SSDI, a five-month waiting period applies before benefits start, so back pay begins at month six after onset. SSI back pay starts from the month after your application date.
Can I apply for disability benefits online if I'm applying for SSI?
Not fully. SSA's online portal handles SSDI applications completely, but SSI requires a personal interview, either by phone or in person. Call 1-800-772-1213 to start the SSI process and schedule the required interview. SSA keeps expanding its online options, but as of 2024 the full SSI application still needs a representative interaction.
What is a consultative examination and do I have to go?
A consultative examination (CE) is an appointment SSA schedules with a contracted doctor when your own records don't give DDS enough to decide. You're strongly expected to attend. Missing a CE without rescheduling almost always results in a denial for failure to cooperate. Call DDS immediately if you need to reschedule. Most offices work with reasonable requests.
Will applying for disability benefits affect my other benefits?
SSDI approval leads to Medicare. SSI approval usually triggers Medicaid. SSDI income counts toward SSI's income limits, which can reduce your SSI payment if you receive both. VA compensation counts as income for SSI. If you get workers' compensation or other public disability benefits, those may offset your SSDI payment under SSA's offset rules.
What is the SGA limit for disability benefits in 2024?
In 2024, the Substantial Gainful Activity (SGA) limit is $1,550 a month for non-blind disabled applicants and $2,590 a month for blind applicants. These figures adjust annually. Earn more than the SGA amount that applies to you and SSA denies your disability claim at Step 1 without reviewing your medical condition.
