What Is a Standard Deduction?

The standard deduction is a fixed dollar amount the IRS lets every taxpayer subtract from adjusted gross income before calculating tax — no receipts, no itemized list required. It's set annually based on filing status, and for the large majority of filers it's simply larger than what they'd get by itemizing.

Before 1944, every taxpayer had to itemize every deductible expense individually. The standard deduction was introduced to simplify filing — and after the 2017 Tax Cuts and Jobs Act roughly doubled it, itemizing became the exception rather than the rule. Today, around 90% of taxpayers take the standard deduction because their mortgage interest, state taxes, and charitable gifts combined don't exceed it.

2024 Standard Deduction Amounts

Filing Status2024 Standard Deduction
Single$14,600
Married filing jointly$29,200
Married filing separately$14,600

Filers 65+ or legally blind get an additional $1,550 (married) or $1,950 (single/HOH) per qualifying condition, stacked on top of the base amount.

Worked Example: $70,000 Single Filer

Suppose your AGI is $70,000 and you're single with no dependents. You total your potential itemized deductions: $6,200 mortgage interest, $4,800 state/local taxes (SALT-capped), and $1,000 in charitable gifts — $12,000 total.

OptionDeduction AmountTaxable Income
Itemize$12,000$58,000
Standard deduction$14,600$55,400

Because $14,600 beats $12,000, this filer takes the standard deduction — no itemized receipts needed — and ends up with $2,600 less taxable income than if they'd itemized.

Frequently Asked Questions

What is the standard deduction in simple terms?

It's a fixed dollar amount the IRS lets you subtract from your income before calculating tax, with no receipts or itemized list required. The amount depends on your filing status.

Should I take the standard deduction or itemize?

Take whichever is larger. Add up your itemizable expenses (mortgage interest, state/local taxes up to $10,000, charitable gifts, large medical costs); if that total exceeds your standard deduction, itemize instead.

How much is the standard deduction for 2024?

For the 2024 tax year, it's $14,600 for single filers, $29,200 for married filing jointly, and $21,900 for head of household. Amounts are adjusted annually for inflation.

Do I get a bigger standard deduction if I'm over 65?

Yes. Taxpayers who are 65 or older, or blind, receive an additional amount on top of the base standard deduction — an extra $1,550 to $1,950 per qualifying condition for 2024, depending on filing status.

Can I itemize and also take the standard deduction?

No. You must choose one or the other for a given tax year — you can't combine them. Most filers (roughly 90%) take the standard deduction because it's simpler and often larger post-2017 tax reform.
