Take whichever is larger: the standard deduction or your itemized deductions. For 2026 the standard deduction is $16,100 for single filers and married filing separately, $32,200 for married filing jointly and surviving spouses, and $24,150 for head of household, per IRS Revenue Procedure 2025-32. Those figures are your break-even: itemize only if your Schedule A total beats yours, and only the excess is a gain.
A deduction is not a credit or a refund. It lowers the income that is taxed, so its value is the deduction times your marginal rate. See how federal tax brackets work.
The amounts, 2025 and 2026
The One Big Beautiful Bill Act (Public Law 119-21) made the larger standard deduction permanent and set the 2025 amounts, which Rev. Proc. 2025-32 then indexed for 2026.
| Filing status | 2025 | 2026 |
|---|---|---|
| Single or married filing separately | $15,750 | $16,100 |
| Head of household | $23,625 | $24,150 |
| Married filing jointly or surviving spouse | $31,500 | $32,200 |
For 2026, age 65 or older, or blind, adds $1,650 to the standard deduction ($2,050 if you are unmarried and not a surviving spouse). A dependent's standard deduction is limited to the greater of $1,350 or $450 plus earned income. As of October 7, 2026, I found no IRS revenue procedure with 2027 amounts. The IRS usually publishes them in the fall, so check the IRS inflation-adjusted items page. Until then, our 2027 projection is an estimate, not an official figure.
What the standard deduction saves
A $1,000 credit cuts your tax by $1,000. A $1,000 deduction cuts it by $100 to $370, depending on your bracket.
2025 and 2026 changes that move the break-even
- State and local tax (SALT) cap. The cap was $10,000 for years before 2025. The 2025 Schedule A instructions set it at $40,000 ($20,000 if married filing separately), reduced by 30% of income over $500,000, but not below $10,000. For 2026 the Form W-4 worksheet shows $40,400 and a $505,000 threshold. A bigger cap makes itemizing more likely in high-tax states.
- Charity floor for itemizers. Starting in 2026, only gifts above 0.5% of income count on Schedule A, per the 2026 Form W-4 worksheet. On $90,000 of income, the first $450 of giving does not count.
- Charity for non-itemizers. Starting in 2026, standard deduction filers can deduct up to $1,000 of cash gifts ($2,000 joint), per the same worksheet. This narrows the gap between the two choices.
- Senior deduction. The IRS says people age 65 and older can claim an additional $6,000 for 2025 through 2028 ($12,000 for a qualifying couple), phased out above $75,000 of modified AGI ($150,000 joint). You claim it on Schedule 1-A, not Schedule A, and it comes on top of the standard deduction. See the IRS summary of the new deductions.
- Stable categories. Medical expenses count only above 7.5% of AGI, and mortgage interest is limited to $750,000 of loans for debt taken on after December 15, 2017 ($1,000,000 for earlier loans), per the Schedule A instructions.
The $6,000 senior deduction is separate from the itemizing comparison. A single 66-year-old with $60,000 of income compares $16,100 plus $2,050 (the 2026 age amount) to Schedule A, and still claims the $6,000 on top, for $24,150 in total if they take the standard deduction.
Worked example: itemizing, and how much it earns
A single filer has $90,000 of income, 2026 figures:
| Item | Amount |
|---|---|
| State income tax $8,000 plus property tax $4,000 (under the cap) | $12,000 |
| Mortgage interest | $9,000 |
| Charity $2,500 minus the 0.5% floor ($450) | $2,050 |
| Itemized total | $23,050 |
| Standard deduction | $16,100 |
| Gain from itemizing | $6,950 |
At a 22% marginal rate, that is $1,529 of tax, not $5,071 (22% of $23,050). The standard deduction was always available, so only the $6,950 above it is a gain.
Bunching, with the math
If your deductions sit just under the standard deduction, you can bunch deductible gifts into alternate years. Take the same filer with $13,000 of taxes and mortgage interest and $3,000 of giving each year.
| Plan | Year 1 | Year 2 | Two-year deductions |
|---|---|---|---|
| Give $3,000 each year | $13,000 + $2,550 = $15,550, so standard $16,100 | Same, standard $16,100 | $32,200 |
| Give $6,000 in year 1, $0 in year 2 | $13,000 + $5,550 = $18,550, itemize | $13,000, so standard $16,100 | $34,650 |
Bunching adds $2,450 of deductions, worth $539 at 22%. It also pays the 0.5% floor once instead of twice. Bunching works for gifts you control, such as donations or a donor-advised fund. It does not work for property tax or mortgage interest.
What does not count
Itemized deductions are the Schedule A categories: taxes, mortgage interest, charitable gifts, medical costs above 7.5% of AGI, and a few others. Commuting, personal credit card interest and living costs are not on it.
How to decide in five minutes
- Add state and local taxes paid, up to the cap.
- Add mortgage interest from your lender's Form 1098.
- Add documented gifts above 0.5% of income (2026).
- Add medical costs above 7.5% of AGI.
- Compare with your standard deduction. Take the larger one. The tax bracket headroom tool shows what the extra deduction is worth in your bracket.
If you change jobs or add income, update your withholding as well. See W-4 withholding and your refund.
Frequently asked questions
Can I take the standard deduction and also itemize?
No. It is one or the other for the same return. The senior, tips and overtime deductions are claimed on Schedule 1-A and are separate from that choice.
What is the standard deduction for 2026?
$16,100 for single and married filing separately, $24,150 for head of household, and $32,200 for married filing jointly and surviving spouses, per Revenue Procedure 2025-32.
What is the SALT cap in 2026?
The 2026 Form W-4 worksheet shows $40,400 ($20,200 married filing separately), which applies to filers with income under $505,000 ($252,500 separate).
Is the standard deduction higher at 65?
Yes. For 2026 it adds $1,650, or $2,050 if you are unmarried and not a surviving spouse, and there is a separate $6,000 senior deduction for 2025 through 2028 if your income is under the phase-out.
Do I need receipts if I take the standard deduction?
No. You claim it without documenting expenses.
Are 2027 standard deduction amounts official yet?
Not as of October 7, 2026. I found no IRS revenue procedure with 2027 amounts, so any 2027 figure you see now is a projection.
Can I itemize on my state return if I take the standard deduction federally?
That depends on the state, so check your state's instructions. The federal choice does not decide it automatically.
