Why deductions decide your benefit
SNAP starts with your household's gross monthly income — everything coming in before taxes. It then subtracts allowable deductions to get your net income. Your benefit is roughly the maximum allotment for your household size minus 30% of that net income. So every dollar of deduction you claim cuts your counted income, and lower counted income means a bigger check.
That's the whole game. Two households earning the same paycheck can get very different benefits because one reports childcare and rent the other left off the form. The deductions below are the levers. To run the full math on your own numbers, use the net income calculator, and check the maximum benefit calculator for your household size.
Meet Maria. She lives in Texas with her two kids and earns $2,000 a month as a cashier. We'll subtract each deduction in order and watch her net income drop.
1. The standard deduction (everyone gets it)
Every SNAP household gets a flat standard deduction — no questions, no receipts. It scales with household size. For FY2026 in the 48 contiguous states and D.C., the amounts are:
- $209 — households of 1 to 3 people
- $223 — household of 4
- $261 — household of 5
- $299 — household of 6 or more
Alaska, Hawaii, Guam, and the U.S. Virgin Islands use higher amounts. Maria's household is 3 people, so she gets the $209 standard deduction. Running total: $2,000 − $209 = $1,791.
2. The 20% earned income deduction
If anyone in your household works, SNAP ignores 20% of that earned income. It's a built-in reward for working. Wages, salary, and self-employment net profit all qualify; unearned income (Social Security, unemployment, child support you receive) does not.
Maria earns $2,000 from her job, all of it earned income. 20% of $2,000 is $400. Subtract: $1,791 − $400 = $1,391. This deduction comes off near the top, and for working families it's often the single largest one.
3. Dependent care deduction
If you pay for childcare or for the care of a disabled adult so you can work, look for work, or attend training or school, you can deduct the full out-of-pocket cost. There's no federal cap — it's the actual amount you pay, after any subsidy. That covers daycare, before- and after-school programs, and a babysitter you pay to hold down a job.
Maria pays $300 a month for after-school care for her younger child while she works the closing shift. The full $300 comes off: $1,391 − $300 = $1,091. Keep receipts or a statement from the provider — your caseworker will ask for proof.
4. Child support you pay out
If you're legally obligated to pay child support to someone outside your household and you actually pay it, that money can come off your income. Most states treat court-ordered child support you pay as a deduction; a few exclude it from gross income instead. Either way the result is the same — the support you send out doesn't count against you.
This applies only to child support you pay. Child support you receive counts as unearned income to your household. Maria doesn't pay child support, so nothing changes here: still $1,091. If this applies to you, bring your court order and proof of payment.
5. Medical expenses (elderly or disabled members only)
Households with a member who is 60 or older, or who has a disability, can deduct unreimbursed medical costs above $35 a month. Only the amount over $35 counts. It's one of the most overlooked deductions, mostly because eligible households never report their costs.
What counts is broad: prescriptions and doctor-ordered over-the-counter medicine, doctor and dentist visits, health insurance premiums, Medicare premiums, hearing aids and batteries, eyeglasses, dentures, transportation to medical appointments (mileage included), even the cost of a service animal. If a senior has $135 in monthly medical costs, $100 of that ($135 − $35) is deductible.
Maria's household has no member who is 60+ or disabled, so this one doesn't apply — her running total stays $1,091. But if a grandparent moved in, it could be worth real money. For the program's own guidance, see the USDA special rules for the elderly or disabled.
6. The excess shelter deduction (and the cap)
This is the big one for most renters and homeowners. SNAP lets you deduct shelter costs — rent or mortgage, property taxes, homeowner's insurance, and utilities — but only the part that exceeds half of your income after all the deductions above. That's why it goes last.
How the calculation works
- Add up your monthly shelter costs (rent/mortgage + property tax + insurance) plus a utility allowance.
- Take your income after deductions 1–5 and cut it in half.
- Subtract that half from your shelter costs. What's left is your excess shelter amount.
For FY2026, the excess shelter deduction is capped at $744 a month in the 48 states and D.C. — unless your household has a member who is elderly or disabled, in which case there is no cap and you deduct the full excess. Households with no stable housing can instead claim a homeless shelter deduction of $198.99.
Maria's shelter math
Maria pays $900 rent plus a utility allowance for heat, electricity, and phone. Her income after deductions 1–5 is $1,091, and half of that is $545.50. Her total shelter cost — rent plus the standard utility allowance her state sets — comes to roughly $1,300. Her excess shelter is $1,300 − $545.50 = $754.50, but the cap holds it to $744. Subtract: $1,091 − $744 = $347 net income.
Utilities are usually claimed through a flat Standard Utility Allowance (SUA) rather than itemized bills, and the SUA amount varies by state. Estimate yours with the utility allowance calculator.
The OBBBA utility allowance change
A 2025 federal law, the One Big Beautiful Bill Act (OBBBA), changed how the utility allowance works starting October 1, 2025. Two things shifted:
- Internet is out. States can no longer fold internet or broadband costs into their SUA values. That trims the allowance for affected households, though the exact dollar effect varies by state.
- LIHEAP no longer auto-qualifies most households. A small LIHEAP energy-assistance payment used to automatically qualify a household for the full utility allowance. Now that automatic qualification applies only to households with an elderly or disabled member. Everyone else has to show their actual utility costs to claim it.
If you lost utility help because of these changes, you may need to report your actual utility bills to your state agency to keep your shelter deduction as high as possible. For the policy detail, see the Food Research & Action Center summary.
From net income to a benefit
Maria started at $2,000 gross and landed at $347 net income after all her deductions. Her benefit is the maximum allotment for a household of 3 ($785 in FY2026) minus 30% of net income. 30% of $347 is about $104. So $785 − $104 = roughly $681 a month in SNAP.
Without reporting her childcare and shelter costs, her net income would have been hundreds of dollars higher and her benefit far smaller. That's the lesson: report every deduction you legally qualify for, with proof.
Don't leave deductions on the table
- Tell your caseworker about childcare you pay for, even informally.
- If anyone is 60+ or has a disability, gather every medical receipt — premiums, mileage, and doctor-ordered over-the-counter items all count.
- Report your full rent and utility costs; the standard utility allowance often beats itemizing.
- If you pay court-ordered child support, bring the order and proof of payment.
