What Is a Tax Deductible Expense?

Definition

A tax deductible expense is a cost the tax code lets you subtract from your income before tax is calculated, which lowers the tax you owe. For businesses and the self-employed, deductible expenses must be ordinary, necessary and documented. A deduction saves you a percentage of the expense, based on your tax rates, not the full amount.

Key takeaways

  • A deduction lowers taxable income, so it saves your tax rate times the expense. A $1,000 deduction doesn’t save $1,000.
  • For the self-employed, a business deduction also lowers self-employment tax, so it often saves more than for an employee.
  • Some deductions have limits: most business meals are 50% deductible, business gifts are capped at $25 per recipient per year, and entertainment is generally not deductible.
  • A tax credit is different: it reduces your tax bill dollar for dollar.

What is a tax deductible expense?

“It’s a write-off” is one of the most misunderstood phrases in small business. A deductible expense isn’t free; it’s cheaper. The government shares part of the cost by taxing you on a smaller income. How big that share is depends on your tax bracket, whether you’re self-employed and your state.

How a deduction lowers your tax

Worked example

Priya is a self-employed designer in the 22% federal income tax bracket. She buys $1,000 of software and equipment for her business. Here’s roughly what the deduction saves:

TaxCalculationSaving
Federal income tax$1,000 × 22%$220
Self-employment tax$1,000 × 92.35% × 15.3%≈ $141
State income tax (example 5%)$1,000 × 5%$50
Total saving≈ $411
Simplified. Interactions such as the deduction for half of SE tax and the QBI deduction change the exact figure slightly.

The $1,000 purchase really cost Priya about $589. Without a receipt to prove it, it costs the full $1,000.

An employee in the same bracket would save only the income tax portion, which is why deductions matter more when you’re self-employed.

Limits to know

  • Meals: most business meals are 50% deductible. Entertainment is generally not deductible.
  • Gifts: business gifts are deductible up to $25 per recipient per year.
  • Mixed use: only the business share of a phone, car or internet counts.
  • Capital purchases: equipment and vehicles may need to be depreciated, though the de minimis safe harbor and Section 179 let many small purchases be deducted in the first year.
  • Employees: under current federal law, most unreimbursed job expenses aren’t deductible.

Proof required

A deduction is only as good as its records. You need a receipt or invoice, proof of payment and, for meals, travel, gifts and vehicles, the business purpose. The IRS requires receipts for all lodging and for other travel, gift and vehicle expenses of $75 or more. See substantiation for the full rules, and keep records for at least three years after you file.

Business deductions vs the standard deduction

A common worry is that taking the standard deduction means losing business deductions. It doesn’t. If you’re self-employed, business expenses are subtracted on Schedule C to work out your business profit, before you ever get to the standard or itemized deduction on Form 1040. You can take the standard deduction and still deduct every legitimate business expense.

TypeWhere it goesCan you take it with the standard deduction?

Frequently asked questions

How much does a tax deduction save?

A deduction saves the expense multiplied by your tax rates. In the 22% bracket, a $1,000 deduction saves $220 in federal income tax. If you’re self-employed, it also cuts self-employment tax by about $141, plus any state tax, for roughly $360 to $410 in total.

Do I need receipts for every deduction?

You need records for every deduction, and receipts are the best kind. The IRS requires receipts for all lodging and for other travel, gift and vehicle costs of $75 or more. Smaller costs can be supported by other records, but keeping every receipt is safest.

What is the difference between a deduction and a credit?

A deduction lowers your taxable income, so it saves only your tax rate times the amount. A credit is subtracted directly from the tax you owe, dollar for dollar. A $1,000 credit saves $1,000; a $1,000 deduction saves a fraction of that.

Can employees deduct work expenses?

Most can’t. Under current federal law, unreimbursed employee business expenses aren’t deductible, apart from limited groups such as armed forces reservists, qualified performing artists, fee-basis government officials and eligible educators. Employees should ask their employer to reimburse business costs under an accountable plan instead.
