1. Earned income deduction — 20% of wages
SNAP automatically disregards 20% of all earned income (wages, salary, self-employment). If you earn $2,000 per month, only $1,600 counts. Unearned income like Social Security or unemployment does not get this deduction.
2. Standard deduction
Every household gets a standard deduction based on household size and location. FY 2026 values:
| Region | Household 1–3 | Household 4 | Household 5 | Household 6+ |
|---|---|---|---|---|
| 48 states + D.C. | $209 | $223 | $261 | $299 |
| Alaska | $358 | $358 | $358 | $374 |
| Hawaii | $295 | $295 | $300 | $344 |
| Guam | $420 | $445 | $522 | $598 |
| U.S. Virgin Islands | $184 | $223 | $261 | $299 |
3. Dependent care deduction — no cap
What you pay for child care or care of a disabled adult so you can work, look for work, or attend school or training is fully deductible. There is no dollar cap on this deduction.
4. Child support deduction
Court-ordered child support that you actually pay to someone outside your household is deducted from your income. Informal support without a court order does not count.
5. Medical expense deduction — elderly and disabled members only
Households with a member who is age 60+ or disabled can deduct unreimbursed medical expenses above $35 per month — premiums, prescriptions, co-pays, transportation to appointments, and more. If that member has $135 in monthly medical costs, $100 is deducted.
6. Excess shelter deduction — usually the biggest one
Add your rent or mortgage, property taxes, home insurance, and utility costs. Whatever exceeds half of your income after all other deductions is your excess shelter cost. For most households it is capped at $744 per month in FY 2026 — but households with an elderly or disabled member have no cap.
Homeless households can use a homeless shelter deduction of $198.99 instead when that is more favorable.
Worked example: family of 4
A household of 4 in the 48 states with $1,500 in monthly wages, $550 in other income, $362 in child care costs, and $700 rent:
- Gross income: $2,050 — under the $3,483 gross limit ✔
- Minus 20% of wages (−$300), standard deduction (−$223), dependent care (−$362) → adjusted income $1,165
- Shelter: $700 rent − half of adjusted income ($582.50) = $117.50 excess shelter deduction
- Net income: $1,047.50 — under the $2,680 net limit ✔
- Benefit: $994 maximum − 30% of net income (rounded up to $315) = $679 per month
Run your own numbers in the SNAP calculator — it applies all six deductions automatically.
What to report so you get every deduction
Caseworkers can only apply deductions they know about. When you apply, report and be ready to verify: your rent or mortgage amount (lease or statement), utility responsibility (which bills are in your name), child care or adult care costs tied to work or school (provider statement), court-ordered child support you actually pay (order plus payment records), and — for households with elderly or disabled members — recurring medical costs like premiums, prescriptions, and mileage to appointments. None of these are automatic; unreported expenses simply vanish from the calculation.
The two deduction mistakes that cost the most
Forgetting utility responsibility. In many states, paying a heating or cooling bill triggers a Standard Utility Allowance worth several hundred dollars in the shelter calculation — far more than most people's actual bills. If a utility is in your name, say so.
Not updating child care costs. Dependent care is uncapped, and it changes with school years and work schedules. A $400/month day-care bill you never reported is roughly $120/month in lost benefits, every month.
Frequently Asked Questions
Which SNAP deduction helps the most?
For most working households, the excess shelter deduction is the largest, especially where rent is high. The 20% earned income deduction and the standard deduction apply almost universally, and dependent care is uncapped.
Does SNAP deduct rent from income?
Indirectly. Shelter costs (rent or mortgage, property tax, insurance, utilities) above half of your income after other deductions are deducted, up to $744 per month in FY 2026 — with no cap for households that include an elderly or disabled member.
Can I deduct medical bills for SNAP?
Only if the expenses belong to a household member who is age 60 or older or disabled. Unreimbursed costs above $35 per month are deductible, including premiums, prescriptions, and transportation to care.
Do utilities count for SNAP deductions?
Yes — utility costs are part of the shelter calculation. Many states apply Standard Utility Allowances (fixed amounts) instead of your actual bills, which can make the official calculation differ from a simple estimate.
