What a proof of income letter is and why SSDI asks for it
A proof of income letter is a document from your employer, bank, or another source that states how much money you earn or received during a specific time period. Social Security Disability Insurance (SSDI) asks for this letter because they need to understand your work history and earnings before you became disabled. This information helps them calculate your benefit amount and determine whether you meet the basic requirements for SSDI.
The letter does not have to be fancy or official-looking. It can come from your boss, your company's human resources department, your bank, or whoever holds the record of what you were paid. What matters is that it shows dates, amounts, and comes from someone with direct knowledge of your income.
If you are no longer working, SSDI still needs to see what you earned before you stopped. If you are still working while explore, they need current proof of your earnings to understand your situation.
Key Takeaways

- If your employer will not write a letter, you can use recent pay stubs, tax returns, or bank statements showing deposits instead.
- SSDI will ask for this letter during the process process, and providing it early can speed up your case.
Who can write a proof of income letter for you
Your employer or their HR department is the most common source. If you worked for a company, ask your supervisor or the HR office to write a letter on company letterhead. The letter should include your name, the dates you worked, your job title, and how much you earned per week, month, or year.
If you are self-employed, you can write the letter yourself, but you will need to back it up with tax returns, bank statements, or business records. SSDI will want to see proof that the income you claim actually came in.
If you received income from a source other than a job—such as rental income, disability payments from another program, unemployment benefits, or regular payments from a family member—the organization or person sending that money can write the letter. A bank can also write a letter based on deposits to your account, though this is less common.
What information the letter should include
The letter works best when it contains these details: your full name, the dates you worked or received income, your job title (if applicable), how often you were paid, and the amount of each payment or your total earnings for the period. If the letter comes from an employer, it should be on company letterhead and signed by someone with authority, such as a manager or HR representative.
The letter does not need to be long. A few sentences are enough, as long as they answer the basic questions: Who are you? When did you work or receive this income? How much did you earn? Here is a straightforward example of what one might look like:
This is to certify that [Your Name] worked as a [Job Title] at [Company Name] from [Start Date] to [End Date]. During this time, [he/she/they] earned [amount] per [week/month/year]. [Signature and title of person writing the letter]
What to do if your employer will not write a letter
If your former employer is out of business, will not respond, or refuses to write a letter, SSDI will accept other documents that prove your income. Pay stubs are the strongest alternative—they show your name, the dates you worked, and exactly what you earned. If you have them, gather as many as you can from the time period SSDI is asking about.
Tax returns also work well. Your federal income tax return (Form 1040) and any schedules that show self-employment income or wages are official records that SSDI trusts. You can get copies from the IRS if you no longer have yours.
Bank statements showing regular deposits from your employer or income source can also serve as proof. Highlight the deposits that came from work and write a note explaining what they are. W-2 forms from your employer are another strong option—SSDI can verify these directly with the Social Security Administration's records.
How far back SSDI looks at your income
SSDI typically asks for income information from the past year or two, but the exact time period depends on when you stopped working and when you are explore. During your process, SSDI will tell you which months or years they need covered. Provide proof for whatever period they request.
If you have been out of work for several years, SSDI may only ask for income from the year before you stopped working. If you are still working, they will want current proof of what you are earning now. Ask your SSDI caseworker or the Social Security office which time period to focus on if you are unsure.
When to send the letter and how to submit it
You can provide the proof of income letter at any point during your SSDI process, but sending it early helps move your case along. If you are explore in person at a Social Security office, bring the letter with you. If you are explore online or by mail, include it with your other documents.
If you are working with a Social Security representative or a disability advocate, give them the letter and they will make sure it gets into your file. If you are handling the process yourself, keep a copy for your records and note the date you submitted it. If SSDI asks for more information later, you will have proof that you already sent this document.
You can submit documents by mail, in person at your local Social Security office, or through your online Social Security account if you have one set up. Ask which method is fastest for your situation.
What happens after you submit the letter
Once SSDI receives your proof of income letter, they use it to verify your work history and calculate your benefit amount. They may also contact your employer directly to confirm the information in the letter. This is normal and does not delay your case—it is part of how SSDI checks the facts.
If there is a discrepancy between what the letter says and what SSDI's records show, they will contact you to ask about it. This sometimes happens if there was a gap in reporting or if your employer reported different amounts to Social Security than what you remember earning. Having your pay stubs or tax returns on hand makes it straightforward to clear up these questions.
Frequently Asked Questions
Can I use a letter from a family member who paid me for work?
Yes, but SSDI will want to see more than just the letter. Bring bank statements showing the deposits, a written agreement about the work and pay, or tax records if you reported the income. SSDI needs to confirm that the income was real and reported properly.
What if I worked under the table and have no proof?
This makes your case harder but not impossible. Gather whatever you can: bank deposits, text messages about pay, witness statements from coworkers, or tax returns if you reported the income. SSDI will review what you have and may ask follow-up questions about the work itself.
Do I need a letter if I have recent pay stubs?
Not necessarily. Pay stubs are often enough on their own. However, if there is a gap between your last pay stub and when you stopped working, a letter from your employer explaining the gap can be helpful. Ask your SSDI caseworker what they prefer.
Can I submit a letter written by someone other than my employer?
Yes, if that person has direct knowledge of your income. A supervisor, coworker, accountant, or bookkeeper can write the letter if they know what you earned. The stronger the person's connection to your pay records, the more weight SSDI gives the letter.
How long does it take SSDI to verify the income information?
Verification usually takes a few weeks to a couple of months, depending on how busy the Social Security office is and whether they need to contact your employer. You do not need to do anything while they verify—just wait for them to contact you if they have questions.
