Tax Deduction vs Tax Credit

How the IRS defines each (US)
Where each fits on a return (US)

A tax deduction lowers the income your tax is figured on, and a tax credit lowers the tax itself. So a deduction is worth the amount times the tax rate on the income it removes. In the tax year 2026 sample below, a $1,000 deduction lowers a single filer's federal income tax by $120, and a $1,000 credit lowers it by $1,000. These are US federal rules; ask your accountant how they apply to you.

Billed publishes this page. It's general information about US federal tax, not tax advice. The IRS quotes come from the IRS page Credits and deductions for individuals (last reviewed October 9, 2026) and the IRS news release IR-2025-103 (October 9, 2025) on tax year 2026 figures, all opened on October 30, 2026.

How the IRS defines each (US)

The IRS says:

Deduction: "A deduction is an amount you subtract from your income when you file so you don’t pay tax on it."
Credit: "A credit is an amount you subtract from the tax you owe."
Refundable credits: these are covered, with the IRS's wording, in the tax write-off guide.

The guide to what a tax write-off is covers write-offs, what makes a business expense deductible and unpaid invoices. This page compares the two and shows the 2026 figures.

Where each fits on a return (US)

Deductions come off income before the tax is figured. Credits come off the tax after it's figured. The IRS adds that you can use both: "You can claim credits and deductions when you file your tax return to lower your tax."

On deductions for individuals, the IRS says:

"Most people take the standard deduction, which lets you subtract a set amount from your income based on your filing status."
"If your deductible expenses and losses are more than the standard deduction, you can save money by deducting them one-by-one from your income (itemizing)."
"You can deduct these expenses whether you take the standard deduction or itemize:" The list includes "Business use of your car" and "Business use of your home".

For tax year 2026, IR-2025-103 says: "For single taxpayers and married individuals filing separately, the standard deduction rises to $16,100 for tax year 2026".

Tax rates for 2026 (US)

A deduction's value depends on the rate on the income it removes. How the IRS's layered tax brackets work is explained, with the IRS's wording, in the tax write-off guide.

For tax year 2026, IR-2025-103 lists, for single filers:

"The lowest rate is 10% for incomes of single individuals with incomes of $12,400 or less"
"12% for incomes over $12,400"
"22% for incomes over $50,400"

Sample: a $1,000 deduction vs. a $1,000 credit (tax year 2026)

The figures here are a sample for the 2026 tax year. A single filer has $15,000 of taxable income after the standard deduction, and no other credits. The sample covers federal income tax only.

Tax before either item: 10% × $12,400 = $1,240. 12% × ($15,000 − $12,400) = 12% × $2,600 = $312. Total: $1,240 + $312 = $1,552.
With a $1,000 deduction: taxable income is $15,000 − $1,000 = $14,000. 10% × $12,400 = $1,240, and 12% × $1,600 = $192. Total: $1,432, which is $120 lower (12% × $1,000).
With a $1,000 credit instead: $1,552 − $1,000 = $552, which is $1,000 lower, because the tax owed ($1,552) is more than the credit.

In the tax write-off guide's sample (tax year 2025), the same $1,000 deduction lowers tax by $220 for a filer in the 22% layer. Whether a deduction or credit applies to you depends on its own rules; ask your accountant.

Where Billed fits

Deductions for business expenses depend on records. Billed's expenses and receipts page says: "An expense in Billed records who you paid, when, how much and which category it belongs to, with the receipt attached to the same entry."
