Most SNAP applicants I sat across from in Columbus had no idea that "income" for SNAP is not the number on their paystub. It's the number that's left after seven specific deductions are applied. The difference between someone getting $23 a month (the federal minimum benefit) and someone getting $320 a month often comes down to whether the caseworker remembered to ask the right questions about shelter, child care, and medical expenses.
This cheat sheet is the reference I wish I had been able to hand people on day one. It covers every deduction in the order the SNAP net-income calculation actually applies them, with the 2026 dollar figures and the mistakes I saw most often at the county office.

The 7 SNAP Deductions, In Order
The USDA net income calculation runs in a specific sequence. You don't get to pick the order. Earned income comes off first, then the standard deduction, then dependent care, then child support, then the medical expense deduction for elderly or disabled household members, then the excess shelter deduction.
Knowing the order matters because the shelter deduction is capped at 50% of the income left after the earlier deductions are applied, so every dollar you can shave off earlier makes the shelter cap more generous.
| # | Deduction | 2026 Amount | Who Qualifies |
|---|---|---|---|
| 1 | Earned Income Deduction | 20% of gross earned income | Anyone with wages or self-employment income |
| 2 | Standard Deduction | $204 (1–3 person HH), $236 (4 person), $268 (5 person), $301 (6+ person) in 48 states & DC | All households (automatic) |
| 3 | Dependent Care Deduction | Actual cost, no cap (for work, training, or education) | Households paying for care of a child under 12 or incapacitated adult |
| 4 | Child Support Payment Deduction | Actual legally obligated child support paid to a non-household member | Households paying court-ordered child support |
| 5 | Medical Expense Deduction | Out-of-pocket medical costs over $35/month for elderly (60+) or disabled members | Households with at least one elderly or disabled member |
| 6 | Homeless Shelter Deduction | $179.66/month (flat, 2026) | Households that are homeless but not receiving free shelter |
| 7 | Excess Shelter Deduction | Rent/mortgage + utilities − 50% of net income after deductions 1–5; capped at $712 unless elderly/disabled | All households with shelter costs exceeding 50% of net income |

1. The Earned Income Deduction (20%)
For every dollar you earn from wages or self-employment, SNAP disregards 20 cents. This is the single biggest reason working families are often better off in SNAP than they expect. A household earning $2,000 a month at a warehouse job doesn't have $2,000 counted against them — they have $1,600 counted.
The deduction is automatic; you don't have to apply for it. But you do have to report your income correctly. If your paystub shows $1,000 gross and $850 net after taxes, SNAP uses the $1,000 number, applies the 20% deduction, and counts $800. People routinely confuse gross and net here and end up underestimating their benefit.
Self-employment income gets the same 20% deduction, on top of business expense deductions. So a gig driver with $3,000 in fares and $600 in gas, maintenance, and platform fees reports $2,400 net self-employment income, then the 20% SNAP deduction brings the counted income down to $1,920.
This one is free money, basically. Every SNAP household gets a flat standard deduction based on household size, no questions asked. In 2026 a single-person household in the 48 states gets $204 off the top. A family of four gets $236. The deduction is automatic and you don't have to prove anything to receive it.
The only thing to watch is that the standard deduction scales with household size only up to 6 people — households of 6, 7, 8, or more all get the same $301. This is one of the reasons a 7-person household can sometimes end up with a slightly lower per-person benefit than expected.
3. The Dependent Care Deduction
If you pay someone to watch your child under 12 (or a disabled adult of any age) so you can work, look for work, attend job training, or go to school, you can deduct the full cost. There's no cap. This deduction is wildly underused.
In my experience, about half of eligible families didn't claim it because they didn't realize after-school programs, summer day camps, and even a neighbor you pay cash to watch your kid while you work a shift all count. Keep receipts. If you pay a relative, write down the agreement — a simple text message chain is usually enough documentation.
4. The Child Support Deduction
If you pay legally obligated child support to someone outside your household — meaning a court order is in place — you can deduct the full amount. This one trips people up because informal arrangements don't count.
If you voluntarily send $400 a month to your ex with no court order, SNAP doesn't allow the deduction. If a court order requires $400, you can deduct it. Bring the court order and proof of payment (cancelled checks, bank statements, garnishment records) to your interview.
5. The Medical Expense Deduction
This is the deduction that pays for itself many times over for seniors and disabled households. If anyone in your household is 60 or older, or receives disability benefits like SSI or SSDI, you can deduct out-of-pocket medical expenses that exceed $35 a month. There's no upper cap. Common expenses people forget to claim:
- Medicare Part B premiums ($185.00/month in 2026 for most people, $259.60 for higher-income beneficiaries)
- Medicare Part D premiums
- Supplemental insurance (Medigap) premiums
- Dental work, eyeglasses, hearing aids, and co-pays
- Transportation to medical appointments (mileage at the IRS rate of 67¢/mile in 2026, or actual gas + parking)
- Over-the-counter medications prescribed by a doctor
- In-home attendant care
For a senior with $1,800 in monthly income, $200 in Medicare premiums, $80 in co-pays, and $50 in transportation costs, the medical deduction alone is $295 ($330 total medical minus the $35 threshold).
That deduction flows through to the shelter calculation too, often adding another $80–$150 to the monthly benefit. I've seen cases where claiming medical expenses properly doubled a senior's SNAP benefit.
6. The Homeless Shelter Deduction
If you're homeless and not staying in a shelter that provides free housing, you get a flat $179.66 deduction per month in 2026 without having to prove any shelter expense.
This is a relatively new deduction (rolled out nationally in 2024) and many caseworkers still forget to apply it. If you're couch-surfing, sleeping in your car, or living in a motel you pay for yourself, ask specifically about the homeless shelter deduction at your interview.
7. The Excess Shelter Deduction
This is usually the largest deduction and the one where people lose the most money. SNAP allows you to deduct shelter costs (rent or mortgage, property taxes, homeowner's insurance, and the standard utility allowance or actual utility costs) that exceed 50% of your household's income after deductions 1–5 have been applied.
For most households, there's a cap on this deduction — $712 a month in 2026. Households with an elderly or disabled member are exempt from the cap.
The Standard Utility Allowance (SUA) is a flat dollar amount your state has calculated to represent average utility costs. In almost every case, claiming the SUA is better than tracking actual utility bills, because the SUA includes heating, cooling, cooking, electricity, and water/sewer/trash in one bundle.
In 2026 the SUA ranges from about $348 in Louisiana to over $700 in some colder-climate states. Check your state's current SUA — it changes every October.
A Worked Example
Here's a real-world scenario I saw weekly at the county office. A grandmother (age 64) lives with her 9-year-old grandson. She works part-time as a school cafeteria worker earning $1,100 a month gross. Her rent is $950. She pays the standard utility allowance in Ohio, which is $603 in 2026. Her Medicare Part B premium is $185 and she has about $60 in monthly co-pays.
| Step | Calculation | Result |
|---|---|---|
| Gross earned income | $1,100 | $1,100 |
| Minus 20% earned income deduction | −$220 | $880 |
| Minus standard deduction (2-person HH) | −$204 | $676 |
| Minus medical expense deduction ($245 medical − $35 threshold) | −$210 | $466 (adjusted net income before shelter) |
| 50% of $466 | $233 | |
| Total shelter costs ($950 + $603 SUA) | $1,553 | |
| Excess shelter deduction ($1,553 − $233) | $1,320 | But capped at $712 since no elderly/disabled household exemption (she IS 60+, so cap does NOT apply) |
| Final net income | $466 − $1,320 = negative | $0 net income → maximum SNAP benefit |
Because the grandmother is 60+, the excess shelter cap doesn't apply. The deduction is so large it zeroes out her net income, which means she qualifies for the maximum SNAP benefit for a 2-person household — $536 a month in 2026.
Without the medical deduction and the uncapped shelter deduction, she'd have been counted with $466 in net income and received only about $300 a month. The difference is $2,800+ a year.
Documentation to Bring to Your Interview
The deductions only work if you can prove them. Here's what to bring:
- Earned income: Your last 4 weeks of paystubs (or 30 days, whichever is more)
- Self-employment: A simple profit-and-loss statement for the last 30 days, plus your most recent tax return if available
- Standard deduction: Nothing — it's automatic
- Dependent care: Receipts, a letter from the provider, or a written statement of the arrangement
- Child support: The court order and proof of payment (bank statements, cancelled checks, or garnishment records from your employer)
- Medical expenses: Receipts, Medicare premium notices, pharmacy printouts, and a simple mileage log
- Shelter: Your current lease or mortgage statement, property tax bill, homeowner's insurance declaration page, and your most recent utility bills (or just ask for the SUA)
The biggest single thing I tell people: don't leave deductions on the table because the paperwork feels annoying. A 30-minute trip to gather receipts can be worth $200+ a month. If you're not sure whether something qualifies, claim it and let the caseworker sort it out — they're required to document why a deduction was denied, and you have appeal rights if you disagree.
