Standard Deduction

The standard deduction is a flat dollar amount the IRS lets you subtract from your income before calculating what you owe in taxes — no receipts, no itemizing, just a fixed reduction based on your filing status. For 2026, the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly. The Tax Cuts and Jobs Act (TCJA) of 2017 roughly doubled the standard deduction — from $6,350 to $12,000 for single filers at the time — which simultaneously made itemizing far less valuable for most households. Today roughly 87% of taxpayers take the standard deduction rather than itemizing. That shift has practical consequences: mortgage interest, charitable donations, and state and local taxes (SALT) only reduce your federal tax bill if they push your deductions above the standard amount. The standard deduction is inflation-indexed each year, and people age 65+ or who are blind get an additional amount on top.

Current Law (2026)

The standard deduction reduces taxable income for filers who do not itemize. It is inflation-indexed annually.

Legal Authority

26 U.S.C. § 63 — Taxable income defined
IRC Section 63(c) — defines the standard deduction amounts
IRC Section 63(f) — additional amounts for aged and blind
IRC Section 1(f) — inflation adjustment using chained CPI-U

How It Works

The choice between itemizing and taking the standard deduction is a single comparison: add up your mortgage interest, state and local taxes, charitable contributions, medical expenses above 7.5% of AGI, and other qualified deductions — if the total exceeds your standard deduction amount, itemizing saves more tax. If not, the standard deduction wins and requires no receipts or documentation. With the post-TCJA standard deduction at $32,200 for married couples filing jointly, roughly 87% of taxpayers find the standard deduction higher than their itemized total, which is why mortgage interest, charitable giving, and SALT only reduce federal taxes for the minority with enough deductions to clear that bar.

The higher post-TCJA standard deduction is permanent current law under 26 U.S.C. § 63(c) — not a temporary provision set to expire. Each year, the IRS adjusts the amounts for inflation using chained CPI-U (IRC § 1(f)), a slower-growing index than traditional CPI. The practical consequence: the standard deduction grows slightly more slowly than overall inflation, gradually narrowing the gap between the standard deduction and what many itemizers could deduct — an estimated $200–$400 per filer annually in additional tax compared to traditional CPI indexing since 2018.

For dependent filers — people who can be claimed as a dependent on another taxpayer's return — the standard deduction is capped. Under IRC § 63(c)(5), a dependent's standard deduction is limited to the greater of $1,350 or earned income plus $450, up to the regular standard deduction for that filing status. A college student earning $8,000 from part-time work gets a standard deduction of $8,450 ($8,000 + $450). Unearned income — dividends, capital gains, trust distributions — does not increase the dependent standard deduction and may be taxed at the parent's rate under the "kiddie tax" rules.

How It Affects You

If you're a typical W-2 employee: You almost certainly take the standard deduction — about 90% of filers do since TCJA roughly doubled it. For a married couple filing jointly with a mortgage, you'd need more than $32,200 in combined SALT, mortgage interest, charitable contributions, and other itemized deductions to benefit from itemizing. A homeowner in a moderate-tax state with a $300,000 mortgage paying $12,000 in mortgage interest and $8,000 in property taxes hits $20,000 — still $12,200 short of the married standard deduction. Add $5,000 in state income taxes (capped at the $10,000 SALT limit), and you're at $25,000 — still below the threshold. Unless you have a large mortgage, live in a very high-tax state, and give significantly to charity, the standard deduction wins and itemizing isn't worth the paperwork.

If you're close to the itemizing threshold: Consider "bunching" — concentrating deductions into alternate years. Make two years of charitable contributions in one year (or use a donor-advised fund), prepay property taxes where allowed, and schedule elective medical procedures in the same year. Itemize in the bunching year, take the standard deduction the next year. A couple with $28,000 in annual deductions who bunches could itemize $56,000 one year and take the $32,200 standard deduction the next — saving $2,000-$4,000 over two years compared to taking the standard deduction both years. A donor-advised fund (DAF) makes bunching charitable contributions simple: contribute several years of donations at once, get the deduction immediately, and distribute to charities over time.

If you're 65 or older: The additional standard deduction ($2,050 for single/HOH, $1,650 per qualifying condition for married) is automatic and stacks with the regular amount. A single filer over 65 gets $18,150 in total standard deduction; a married couple both over 65 gets $35,500. Beginning with 2025 tax returns, seniors may also qualify for a separate temporary senior deduction on top of these amounts — check IRS Publication 501 for the current year's combined figure. These higher amounts make itemizing even less likely for most retirees, meaning your Social Security, pension, and IRA withdrawals are sheltered from taxable income up to the combined deduction amount before you owe a dollar in tax.

If you're a dependent being claimed by someone else: The standard deduction for dependents is limited — you get the greater of $1,350 or your earned income plus $450, up to the regular standard deduction. For a college student working a part-time job earning $8,000, the standard deduction is $8,000 + $450 = $8,450. Unearned income (dividends, capital gains, trust distributions) is subject to the "kiddie tax" and may be taxed at the parent's marginal rate regardless of the dependent's standard deduction. If you receive significant investment income as a dependent, the standard deduction benefit is smaller than it appears.

State Variations

Most states with an income tax offer their own standard deduction, but amounts vary widely. Some states (like California) have much lower standard deductions than the federal level. A few states require itemizing if you itemize federally, or vice versa. States with no income tax (AK, FL, NV, SD, TN, TX, WA, WY) have no state standard deduction.

Recent Developments

Higher standard deduction made permanent: The One Big Beautiful Bill Act locked in the larger modern standard deduction structure, so the 2026 amounts above are current law rather than a temporary extension scenario.
Separate senior deduction added: Beginning with 2025 returns, taxpayers age 65 and older may also qualify for a separate temporary senior deduction, which sits on top of the basic standard deduction rules described here.
Proposals to go further: HR 523 would permanently raise the standard deduction to $18,000/$12,000 (single/married) with a new inflation formula. HR 1833 would add temporary bonus amounts for 2026-2027 and rebrand it as the "guaranteed deduction." HR 1130 would increase the senior additional deduction from $1,550/$2,050 to $5,000 with inflation indexing — a significant benefit for retirees.
Chained CPI erosion: The standard deduction is indexed using chained CPI-U (a slower-growing inflation measure adopted under TCJA). Over time, this means the standard deduction grows more slowly than actual inflation, gradually pushing more income into taxable territory. The cumulative effect since 2018 is estimated at $200-$400 per filer in additional tax compared to traditional CPI indexing.
