Taxes and income
Standard vs. Itemized Deductions
Reviewed by the Smart Finance Calculators Editorial TeamLast reviewed:
Every filer reduces their adjusted gross income by either the standard deduction or their itemized deductions, whichever is larger. The standard deduction is a fixed amount based on filing status, while itemizing means adding up specific deductible expenses one by one. Most filers take the standard deduction because it exceeds their itemizable expenses, but for some households, particularly homeowners with a large mortgage or generous charitable giving, itemizing saves more.
This guide explains both options, the most common itemized deductions, and how to compare them using current-year figures.
Key takeaways
- You may take either the standard deduction or itemized deductions, whichever is larger — not both.
- The standard deduction amount depends on your filing status and is adjusted annually for inflation.
- Common itemized deductions include mortgage interest, state and local taxes (SALT), charitable contributions, and certain medical expenses.
- Itemizing requires documentation and recordkeeping that the standard deduction does not.
The standard deduction
For the 2026 tax year, the standard deduction is $16,100 for single filers and those married filing separately, $32,200 for married couples filing jointly and qualifying surviving spouses, and $24,150 for heads of household. These figures are set by the IRS and adjusted for inflation, so always confirm the current-year amount before filing.
The standard deduction requires no receipts or documentation and is simpler to claim, which is a meaningful advantage even when it is close in size to what you might itemize.
Common itemized deductions
Mortgage interest
Interest paid on a qualifying home mortgage, up to certain loan-balance limits set by the IRS, can be deducted if you itemize.
State and local taxes (SALT)
State and local income or sales taxes, plus property taxes, can be deducted up to a combined federal cap, which has changed under different tax laws — check the current limit before estimating.
Charitable contributions
Donations to qualifying charitable organizations are deductible if itemizing, generally up to a percentage of your adjusted gross income depending on the type of gift.
Medical expenses
Unreimbursed medical and dental expenses are deductible only to the extent they exceed a percentage threshold of your adjusted gross income, which excludes many filers from benefiting unless expenses are unusually high.
Worked example: comparing the two for a single filer, 2026
Suppose a single homeowner paid $9,500 in mortgage interest, $10,000 in state and local taxes (at the federal cap), and made $2,500 in charitable contributions during 2026, for total itemized deductions of $22,000.
Comparing that to the 2026 single standard deduction of $16,100, itemizing produces $5,900 more in deductions ($22,000 − $16,100), which would reduce this filer’s taxable income further than taking the standard deduction.
If this same filer had only $12,000 in itemizable expenses, the standard deduction of $16,100 would be larger, and taking it would produce a lower taxable income with far less paperwork.
2026 standard deduction by filing status
| Filing status | 2026 standard deduction |
|---|---|
| Single / married filing separately | $16,100 |
| Married filing jointly / qualifying surviving spouse | $32,200 |
| Head of household | $24,150 |

Recordkeeping and when to seek help
Itemizing requires keeping receipts, statements, and documentation to support each deduction claimed, in case of an IRS inquiry. Because deduction rules, caps, and thresholds change periodically, a tax professional can be valuable if your situation is complex, such as significant medical expenses, self-employment income, or major charitable giving.
How to use the Tax Estimator
Enter your filing status and choose the standard deduction or itemized deductions to compare your estimated taxable income and federal tax under each option.
Open the Tax EstimatorCommon mistakes to avoid
- Itemizing without keeping the documentation required to support each deduction.
- Forgetting that SALT deductions are capped, not fully unlimited.
- Assuming medical expenses are deductible in full rather than only above a percentage-of-income threshold.
- Not recalculating each year, since a change in mortgage balance or giving can flip which option is larger.
Practical takeaways
- Add up your itemizable expenses each year and compare them to the current standard deduction.
- Keep documentation for any itemized deduction, even if you do not end up needing it.
- Recheck the comparison annually as your expenses and the standard deduction amount both change.
- Consider professional tax help if your situation involves significant itemizable expenses.
Frequently asked questions
For the 2026 tax year, the standard deduction is $16,100 for single filers and those married filing separately, $32,200 for married couples filing jointly and qualifying surviving spouses, and $24,150 for heads of household. Confirm the current figure with the IRS before filing, since these amounts are adjusted annually for inflation.
Add up your itemizable expenses — mortgage interest, state and local taxes up to the cap, charitable contributions, and medical expenses above the applicable threshold — and compare the total to your standard deduction for your filing status. If the itemized total is larger, itemizing generally reduces your taxable income further.
Yes, the SALT deduction is capped at a combined dollar limit for state and local income or sales taxes plus property taxes, rather than being fully unlimited. The specific cap has changed under different tax laws, so confirm the current-year limit before estimating your itemized deductions.
No. Only unreimbursed medical and dental expenses that exceed a set percentage of your adjusted gross income are deductible, which means many filers with typical medical costs do not clear the threshold. Significant medical expenses in a single year are the scenario where this deduction is most likely to matter.
Yes. You choose whichever is larger each year you file, and there is no requirement to use the same method as the prior year. Since your itemizable expenses and the standard deduction amount can both change annually, it is worth comparing them each tax season.
No. The standard deduction does not require documentation of specific expenses, which is one reason it is simpler for many filers. Documentation and recordkeeping become important only if you choose to itemize and need to support those specific deductions.
