What income deductions are used to calculate SNAP net income in 2025?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
SNAP calculates “net income” by subtracting a small set of federally allowed deductions from gross monthly household income; the program then reduces the household’s maximum allotment by 30% of that net income to determine the monthly benefit (example: 30% of $600 = $180) [1]. Key recurring deductions include a standard deduction (varies by household size), a 20% earned income deduction, allowable shelter and utility deductions (with a statewide cap), dependent care, medical (for elderly/disabled) and certain child-support-related deductions; the standard deduction and shelter cap were raised for FY2025–FY2026 [1] [2] [3].
1. How SNAP turns paychecks into “net income” — the headline math
SNAP first measures gross monthly income (all non‑excluded income) and then subtracts allowable deductions to arrive at net income; benefit amounts equal the household’s maximum allotment for its size minus 30% of that net income (illustrated in the CBPP example where a three‑person family with $600 net income receives $785 − $180 = $605) [1]. The federal gross‑income threshold is generally 130% of the federal poverty level and net income after deductions must be at or below 100% of the poverty line to qualify in most cases [1] [4].
2. The standard deduction — automatic and indexed
Every SNAP household receives a standard deduction that varies by household size; for fiscal 2026 the typical amounts in the 48 contiguous states and D.C. are in the $209–$299 range depending on household size, and the FY2025 COLA raised the standard deduction to about $204 for households of one to three in some updates [1] [3]. States and territories may have slight variations, and the One Big Beautiful Bill Act of 2025 prompted updates on FNS pages noting changes are being implemented [2].
3. The 20% earned income deduction — reduces work income first
SNAP automatically takes a 20% deduction from earned income before other deductions are applied; this is a fixed, statutory deduction designed to recognize work‑related costs and is cited on USDA/FNS guidance and special‑rules materials [2] [5].
4. Shelter, utility and homeless shelter deductions — important but capped
Households may deduct excess shelter costs (rent or mortgage plus utilities) above 50% of income after other deductions, subject to a federal shelter cap for the contiguous states; the FY2025 COLA increased the shelter cap (noted as $712 for the 48 states and D.C.) and raised the maximum homeless shelter deduction to about $190.30 [3]. States administer these rules and some variation exists by jurisdiction [1].
5. Dependent care and child‑support deductions — narrower usage
Expenses for dependent care (child or adult) needed for work or training can be deducted; child‑support payments also can be deducted in many jurisdictions, though some states replace the deduction with an equivalent income exclusion (CBPP notes dependent care, child‑support and medical deductions are claimed by relatively small shares of households) [1].
6. Medical expenses for elderly or disabled households — a separate pathway
Households with an elderly or disabled member may deduct medical expenses that exceed $35 per month (this population also may only need to meet the net‑income test); FNS special‑rules pages and CBPP describe medical deductions as more frequently used in that subgroup [5] [1].
7. What’s not in these sources — areas reporters must still verify
Available sources do not mention the exact new procedural changes states may have adopted under the “One Big Beautiful Bill Act of 2025” beyond FNS noting it is updating guidance, nor do they provide a single consolidated table of every state’s deviations [2]. State implementation details, whether some states now use exclusions instead of deductions for child support, and any temporary pandemic or shutdown-era adjustments are discussed in some outlets but require checking state‑level FNS pages for confirmation [1] [6].
8. Competing frames and practical impact — deductions matter more than they look
Policy analysts (CBPP) emphasize deductions are central to benefit size and eligibility — a modest shelter or medical expense can lower net income substantially and raise benefits — while state guidance and calculators present variations and examples showing how the same gross pay produces different net SNAP outcomes depending on claimed deductions [1] [7]. Consumer sites and advocacy groups stress that annual COLA updates and recent legislative changes slightly raised standard and shelter caps, modestly helping some households [3] [7].
Limitations: this summary relies on federal guidance (FNS), policy analysis (CBPP), and multiple advocacy/calculator sites; state‑level differences and the full administrative implementation of 2025 legislative changes are not fully documented in the available set and should be checked on your state’s SNAP office page for precise figures and procedures [2] [1].
