Standard Deduction 2024: Amounts by Filing Status and When to Itemize

The standard deduction is the most widely claimed tax break in America — and in 2024, it gets a meaningful inflation bump that benefits nearly every taxpayer. Whether you’re filing as single, married, or head of household, understanding the 2024 amounts, the additional deductions for seniors, and the itemizing decision can make a real difference at tax time.

2024 Standard Deduction by Filing Status

Filing Status	2023 Amount	2024 Amount	Increase
Single	$13,850	$14,600	+$750
Married Filing Jointly	$27,700	$29,200	+$1,500
Head of Household	$20,800	$21,900	+$1,100
Married Filing Separately	$13,850	$14,600	+$750
Qualifying Surviving Spouse	$27,700	$29,200	+$1,500

The standard deduction reduces your taxable income — not your tax bill directly. A $14,600 deduction saves you $14,600 × your marginal rate. For a single filer in the 22% bracket, that’s $3,212 in federal income tax savings.

Additional Standard Deductions: Age and Blindness

Taxpayers who are 65 or older, or legally blind, qualify for extra amounts on top of the standard deduction.

Filing Status	Additional Amount (per condition)
Single or Head of Household	+$1,950
Married (any status) or Qualifying Surviving Spouse	+$1,550

These amounts stack. A single 65+ filer who is also legally blind gets: $14,600 + $1,950 + $1,950 = $18,500

A married couple where both spouses are 65+ gets: $29,200 + $1,550 + $1,550 = $32,300

Should You Itemize or Take the Standard Deduction?

You should itemize only if your allowable itemized deductions exceed your standard deduction amount. For most Americans — about 90% — the standard deduction wins.

What Can You Itemize?

Deduction	2024 Rules
State and local taxes (SALT)	Capped at $10,000 combined (property + income or sales tax)
Mortgage interest	On loan balances up to $750,000
Charitable contributions	Up to 60% of AGI for cash donations
Medical expenses	Amount exceeding 7.5% of AGI
Casualty losses	Federally declared disasters only

Itemizing Math: Single Filer Example

Expense	Amount
Mortgage interest (on $350K loan)	$9,800
Property tax	$5,000
State income tax	$5,000
SALT total (capped)	$10,000
Charitable donations	$2,500
Total itemized	$22,300
Standard deduction	$14,600
Advantage of itemizing	$7,700 more deductible

At a 22% marginal rate, itemizing saves an additional $1,694 in federal taxes. In this scenario, it’s clearly worth itemizing.

When the Standard Deduction Almost Always Wins

• You rent (no mortgage interest deduction)
• You live in a state with no income tax (less SALT to deduct)
• You have a small mortgage with low interest
• Your charitable giving is modest

The Tax Cuts and Jobs Act of 2017 nearly doubled the standard deduction, which is why so many more taxpayers now take it instead of itemizing.

How the Standard Deduction Affects Your W-4 and Withholding

The IRS Publication 15-T withholding tables automatically account for the standard deduction when calculating how much federal income tax to withhold from your paycheck. You don’t manually enter “$14,600” on your W-4.

What your W-4 actually controls:

• Filing status (Single, MFJ, HoH) — determines which withholding table is applied
• Multiple jobs adjustment (Step 2) — critical if you have two incomes in the household
• Dependent credits (Step 3) — reduces withholding if you claim Child Tax Credit
• Additional deductions (Step 4b) — lets you claim itemized deductions, reducing withholding
• Extra withholding (Step 4c) — adds a flat dollar amount if you expect to owe more

If you plan to itemize in 2024 and your itemized deductions exceed $14,600 (single) or $29,200 (MFJ), you can enter the excess amount on Step 4(b) of your W-4. For example, a single filer with $22,000 in expected itemized deductions would enter $7,400 ($22,000 − $14,600). This reduces withholding to account for the extra deductions.

Above-the-Line Deductions: Available Regardless of Which You Choose

The standard vs. itemize decision only affects Schedule A deductions. Several important deductions are “above the line” — they reduce your AGI before the standard/itemize decision is even made.

Above-the-Line Deduction	2024 Limit
Student loan interest	$2,500
HSA contributions (self-only)	$4,150
HSA contributions (family)	$8,300
Traditional IRA (if eligible)	$7,000
Educator expenses	$300
Self-employment tax deduction	50% of SE tax

These deductions reduce your taxable income regardless of whether you itemize or take the standard deduction.

Impact of the Standard Deduction at Various Income Levels (2024)

Gross Income	Standard Deduction	Taxable Income	Approximate Federal Tax	Effective Rate
$25,000	$14,600	$10,400	$1,048	4.2%
$40,000	$14,600	$25,400	$2,878	7.2%
$60,000	$14,600	$45,400	$5,418	9.0%
$80,000	$14,600	$65,400	$9,396	11.7%
$100,000	$14,600	$85,400	$13,528	13.5%
