Form SSA-820-BK is the Work Activity Report the Social Security Administration sends to people on SSDI or SSI who have been self-employed, and you generally have 15 days to complete and return it.1Social Security Administration. Work Activity Report – Self-Employment Your answers tell the SSA whether your business activity rises to Substantial Gainful Activity (SGA), and that determination decides whether your benefits continue, change, or stop.
Why the SSA Sent It and What It’s Deciding
The form arrives when the SSA has information that you’ve done self-employment work since your disability began, since your benefits started, or since your last work review.1Social Security Administration. Work Activity Report – Self-Employment It can show up during an initial application, a continuing disability review, or an appeal.2Social Security Administration. POMS DI 10510.025 – Documenting Self-Employment Cases Using the SSA-820-BK
SSA-820-BK is only for self-employment: any work paid on a 1099-NEC, freelance and independent contractor work, or a business you run yourself. If you’re a W-2 employee, you report on the separate Form SSA-821-BK instead.
For 2026, monthly earnings above $1,690 (or $2,830 if you are statutorily blind) count as SGA.3Social Security Administration. Substantial Gainful Activity For self-employment, though, income alone doesn’t decide the question. The SSA also looks at hours worked, what you actually do in the business, and how much the business depends on your personal labor. That is why the form asks so many detailed questions, and why vague answers create problems.
Before You Start: Pull Your Records
Gather tax returns, bookkeeping records, receipts for any disability-related expenses you paid out of pocket, and notes on any dates your role in the business changed. Guessing at figures the SSA can check against its own records is the fastest way to draw follow-up questions or an adverse decision.
Filling Out the Form Section by Section
Business Identification and Dates
Enter the legal name of your business and the date you started or resumed working. If you’ve had more than one period of self-employment since your disability began, report each separately.
Hours Worked Per Month
The form asks you to place your average monthly hours in one of three brackets: under 45 hours, 45 to 79 hours, or 80 or more.1Social Security Administration. Work Activity Report – Self-Employment This choice carries real weight. Working more than 45 hours a month can produce an SGA finding on its own, because at that level your services are treated as significant to the business regardless of what you earned.2Social Security Administration. POMS DI 10510.025 – Documenting Self-Employment Cases Using the SSA-820-BK Answer from your records, not from an impression.
Net Earnings
Report net earnings, not gross receipts: gross income minus legitimate business expenses. Do not include on this form anything you’ll also claim as a business expense on your annual tax return; the instructions call that out specifically to prevent double-counting.1Social Security Administration. Work Activity Report – Self-Employment
The SSA computes Net Earnings from Self-Employment (NESE) by multiplying your net profit by .9235, the same formula the IRS uses.4Social Security Administration. POMS RS 00820.210 – How to Determine Net Earnings from Self-Employment (NESE) That NESE figure, not your raw profit, is what gets compared against the SGA threshold before deductions.
Description of Duties
Describe what you actually do: bookkeeping, managing employees, physical labor, customer contact, decision-making. The SSA uses this to judge whether your work is comparable to what someone without a disability would do running the same kind of business. “I run the business” tells the reviewer nothing and invites more questions.
Changes in Your Role
If your condition forced you to cut hours, hand off duties, or change how you participate, spell it out with specific dates and the physical or mental limitations that drove the change.2Social Security Administration. POMS DI 10510.025 – Documenting Self-Employment Cases Using the SSA-820-BK “In March 2025, I stopped doing on-site client visits because of chronic pain and hired a contractor to handle them” is far more useful than “my role changed.” This section is where you show reduced involvement in concrete terms.
Deductions That Lower Your Countable Earnings
Three categories of deductions can pull your countable income below the SGA line. Missing them is one of the most common ways self-employed claimants lose benefits they should have kept.
Unpaid Help
If a spouse, child, or someone else does significant unpaid work in your business, the reasonable value of that labor comes off your net income. “Significant” means the work has real commercial value; incidental tasks don’t count.5Social Security Administration. 20 CFR 404.1575 – Evaluation Guides if You Are Self-Employed
Unincurred Business Expenses
These are business costs someone else pays or resources provided free. Common examples include a computer supplied by a vocational rehabilitation agency, or rent paid by a nonprofit. Because these subsidies inflate the profit that appears to come from your own work, the SSA subtracts their value.5Social Security Administration. 20 CFR 404.1575 – Evaluation Guides if You Are Self-Employed List each one with a dollar value and the source.
Impairment-Related Work Expenses
Out-of-pocket costs for items and services you need because of your disability in order to work, including medical devices, specialized transportation, attendant care, and medications, are deducted from your earnings before the SGA comparison. You must have paid for the item or service yourself.6Social Security Administration. POMS DI 10520.001 – Impairment-Related Work Expenses (IRWE) Keep the receipts; the SSA can ask for proof.
How the SSA Scores Your Answers
Knowing the tests helps you fill the form out with intention. If you have received disability benefits for less than 24 months, the SSA applies three tests, and meeting any one can produce an SGA finding:
- Significant services and substantial income. If you run the business alone, any services you perform are significant. If others are involved, your services are significant when you provide more than half the management time or manage the business for more than 45 hours a month.7Social Security Administration. 20 CFR 416.975 – Evaluation Guides if You Are Self-Employed
- Comparability. Your hours, skills, energy, duties, and responsibilities are comparable to those of people without disabilities running the same kind of business in your community.8Social Security Administration. POMS DI 10510.020 – Tests Two and Three of General Evaluation
- Worth of work. Your work is clearly worth more than the SGA threshold measured by its value to the business or what an owner would pay someone else to do it.8Social Security Administration. POMS DI 10510.020 – Tests Two and Three of General Evaluation
After 24 months of benefits, the SSA switches to a countable income test. If your monthly countable income (after allowable deductions) averages above $1,690, that generally counts as SGA, unless the evidence shows you didn’t render significant services that month.9eCFR. 20 CFR 404.1575 – Evaluation Guides if You Are Self-Employed
Getting a Copy and Submitting It
Most people receive the form by mail when the SSA opens a work review. If you need a copy, download it from ssa.gov/forms or pick one up at any Social Security field office.10Social Security Administration. Social Security Forms
You have three ways to return it:
- Online, through the SSA’s document upload tool linked from the forms page.10Social Security Administration. Social Security Forms
- By mail to your local Social Security office. Certified mail with return receipt gives you dated proof.
- In person at the local field office. Ask for a date-stamped copy for your records.2Social Security Administration. POMS DI 10510.025 – Documenting Self-Employment Cases Using the SSA-820-BK
Return it within 15 days.1Social Security Administration. Work Activity Report – Self-Employment If you don’t, the SSA can decide based on whatever it already has, which usually won’t include the unpaid help, unincurred expenses, IRWEs, and role changes that could keep you under the SGA threshold.
After You Submit
The SSA compares your answers against its own records and can ask for supporting proof, especially when your figures don’t match what the agency already has on file.1Social Security Administration. Work Activity Report – Self-Employment You’ll get a determination letter explaining whether your work counts as SGA and how it affects your benefits.
If the SSA Decides Against You
If the determination reduces or stops your benefits, you can request reconsideration. File the request in writing within 60 days of receiving the notice; the SSA presumes you received it five days after the printed date.11Social Security Administration. Understanding Supplemental Security Income Appeals Process
Use Form SSA-561-U2 (Request for Reconsideration). You can submit it in person, by mail, or online.12Social Security Administration. Form SSA-561-U2 – Request for Reconsideration Explain clearly why you disagree and attach anything the original review may have missed: updated financials, medical documentation, dates and details of role changes.
One boundary worth flagging. Form SSA-561-U2 doesn’t cover medical cessation appeals, which use Form SSA-789 instead.12Social Security Administration. Form SSA-561-U2 – Request for Reconsideration And for medical cessation specifically, filing within 10 days of the notice (not 60) lets your benefits continue while the appeal is pending.13Social Security Administration. 20 CFR 404.1597a If reconsideration doesn’t resolve it, the next step is a hearing before an administrative law judge.
