Learn which expenses may lower countable income.
Why deductions matter
SNAP uses countable net income to determine the benefit. A household may have the same gross pay as another but a different net income after eligible expenses. Deductions are part of the official calculation, not optional discounts you request after approval.
The usual sequence
A standard deduction applies automatically. Earned income generally receives a 20% deduction. Eligible dependent care needed for work, training or looking for work and legally owed child support paid outside the household can also count. Households with an older or disabled member can deduct qualifying out-of-pocket medical costs over $35 a month.
Shelter costs need care
Rent or mortgage payments and approved utility allowances enter an excess shelter calculation after the other deductions. In many cases there is a federal cap; households with an older or disabled member can have a different treatment. States often use standardized utility amounts, so adding your exact electric bill to your rent will not always reproduce the agency result.
Bring documentation
Keep lease or mortgage records, childcare receipts, child support documentation, and medical bills if relevant. Ask your caseworker which expenses are allowed and how to report a change. Missing an eligible expense can lower the benefit estimate.
