To decide whether to itemize your deductions or take the standard deduction, do this: figure out what itemized deductions you can take and add them up. If the total is more than the standard deduction for your filing status, then itemize your deductions. Your tax filing software will likely do this for you automatically.

American tax filers — whether individuals, married filing jointly or separately — face a choice when preparing their federal income tax returns. After computing their adjusted gross income (AGI), taxpayers can itemize their deductions (from a list of allowable items) and subtract those itemized deductions, and any applicable personal exemption deductions, from their AGI to arrive at their taxable income amount.

Alternatively, they can elect to subtract the standard deduction for their filing status (and any applicable personal exemption deduction) to arrive at their taxable income. In other words, the taxpayer may generally deduct the total itemized deduction amount, or the standard deduction amount, whichever is greater.

Itemized Deduction versus Standard Deduction comparison chart
Itemized DeductionStandard Deduction
Definition A list of specific qualifying expenses (state/local taxes, mortgage interest, charitable gifts, large medical bills) summed on Schedule A to reduce taxable income. A flat dollar amount set by the IRS, based on filing status, that reduces taxable income with no tracking or documentation.
Decision rule (when to choose) Choose it only when your total qualifying expenses exceed your standard deduction. Example - single filer, 2025: $12,000 SALT + $8,000 mortgage interest + $2,000 charity = $22,000 itemized vs $15,750 standard, so itemize. The simpler default; take it when your qualifying expenses fall below the flat amount for your filing status. The IRS suggests claiming whichever is larger.
2025 amount (filed 2026) No fixed amount - equals the total of your qualifying Schedule A expenses after each category's limits. $15,750 single/MFS; $31,500 MFJ or qualifying surviving spouse; $23,625 head of household.
2026 amount (filed 2027) Same - varies by actual expenses. $16,100 single/MFS; $32,200 MFJ or QSS; $24,150 head of household.
Additional amount for age 65+ or blind None (no age/blindness add-on). Extra per qualifying condition - 2025: $2,000 (single/HoH) or $1,600 (MFJ/MFS) for each of age 65+ and/or blindness; stacks if both apply.
New senior deduction (OBBBA, 2025-2028) $6,000 per qualifying filer age 65+ - available whether you itemize or not; phases out above $75K (single) / $150K (MFJ) MAGI. Same - $6,000 per qualifying filer 65+, 2025 through 2028.
What can be deducted Schedule A categories: medical/dental above the AGI floor, state & local taxes, home mortgage interest, charitable gifts, casualty/theft losses in federally declared disaster areas. Nothing itemized - a single flat amount regardless of actual expenses.
SALT (state & local tax) cap Capped at $40,000 ($40,400 for 2026) under 2025 OBBBA, up from $10,000; covers property tax plus state income or sales tax. Phasedown begins at $500K MAGI for 2025 ($505K for 2026; half for MFS), reducing the cap by 30% of the excess but never below N/A
Mortgage interest limit Interest on up to $750,000 of acquisition debt ($1M for pre-Dec 2017 loans); $750K cap now permanent; PMI again deductible. N/A
Medical expense threshold Only unreimbursed medical/dental expenses exceeding 7.5% of AGI are deductible. N/A
Charitable contributions Deductible on Schedule A (cash gifts generally up to 60% of AGI); new 0.5%-of-AGI floor starting 2026. Generally none, but from 2026 non-itemizers may deduct up to $1,000 (single) / $2,000 (MFJ) in cash gifts above the line.
Schedule A required? Yes No
Documentation Requirement Each deduction must be substantiated (receipts, Form 1098, acknowledgment letters); more recordkeeping and audit exposure. None required.
Eligibility Any filer may itemize; required for nonresident aliens and for a spouse whose partner itemizes. Most filers. Not available to nonresident aliens (limited treaty exceptions), a married-separate filer whose spouse itemizes, or short-year filers from an accounting-period change. Dependents get a limited standard deduction (2025: greater of $1,350
Available to Nonresident aliens? Yes - NRAs with deductions itemize on Schedule A (Form 1040-NR). No (limited treaty exceptions, e.g. certain students from India).
Married filing separately rule If one spouse itemizes, the other must also itemize. Both spouses must use the same method; unavailable if the other itemizes.
Tax form used Form 1040 (or 1040-SR) with Schedule A attached. Form 1040 (or 1040-SR); no Schedule A. Forms 1040EZ/1040A were discontinued after 2017.
Procedure File Form 1040 with Schedule A, listing each qualifying expense after its limits; keep documentation. Enter the flat amount on Form 1040 / 1040-SR; no Schedule A or documentation.
Relation to AMT (Alternative Minimum Tax) Some itemized items (e.g. SALT) are added back for AMT and don't reduce AMT income; others still help. Does not reduce income subject to AMT.
Limitation for high earners OBBBA repealed the old Pease phaseout but caps the tax benefit of itemized deductions at 35% for top-bracket (37%) filers from 2026. No such limitation.
Who typically benefits Homeowners with large mortgages, high-tax-state residents, big donors, or those with major medical bills. Most filers, especially renters and those without large deductible expenses.
Share of taxpayers using it About 10% under TCJA, but the 2025 OBBBA SALT increase to $40K (through 2029) is expected to push this higher, especially in high-tax states. Roughly 90% post-TCJA; likely to ease somewhat as more filers itemize under the higher SALT cap.

Standard Deduction

Standard deduction is a specific dollar amount that you can deduct from your income to reduce your taxable income. The amount of standard deduction depends only on your filing status and is increased every year to adjust for inflation. You are eligible for standard deduction if you have not itemized your deductions and you are either a US citizen, a resident alien (married or single), or a head of a household. Non-resident aliens are not eligible for standard deduction. You may be eligible for higher standard deduction amounts if you meet certain special criteria e.g. you are blind or over 65 years of age.

Standard Deduction Amounts

The applicable standard deduction amounts for tax years 2026 and 2025 are as follows:

Filing status 2026 Standard Deduction Amount 2025 Standard Deduction Amount
Single $16,100 $15,000
Married Filing Jointly $32,200 $30,000
Married Filing Separately $16,100 $15,000
Head of household $24,150 $22,500
Qualifying widow(er) $32,200 $30,000
Additional Amount if at least 65 years old or blind $2,050 for single/head of household filers, and $1,650 per qualifying spouse for married filers $1,600 ($2,000 if using the single or head of household filing status)

Itemized Deductions

Itemized deductions, on the other hand, are expenses which one can list if these expenses belong to a predetermined list of allowable items. The allowable items include payments to doctors, medical insurance premiums, cost of medical equipment and many more. There are differences between the two, and understanding them is imperative in deciding the exact amount of taxable income to be declared.

Expenses that can be itemized

Itemizing deductions would generally be more advantageous if the sum of all itemizable expenses works out to be greater than the standard deduction for the corresponding filing status. The following set of expenses can, in general, be itemized:


Standard Deduction or Itemized? How to Choose

You can choose to itemize your deductions or take the standard deduction — but not both. Making the right choice will save you money. The choice between the standard deduction and itemizing involves a number of factors:

Impact of the Tax Cuts and Jobs Act of 2017

In December 2017, president Trump signed into law a tax reform bill called the Tax Cuts and Jobs Act of 2017. This bill made had several provisions that affect your choice on whether to itemize or take the standard deduction.

First, the standard deduction was raised to $24,000 (increased to $32,200 for the 2026 tax year) for a married couple and $12,000 (increased to $16,100 by 2026) for single filers. This is almost double what it was before. So for a lot of taxpayers, it will be more advantageous to take the standard deduction because the total of all their itemized deductions will not exceed that threshold.

List of Eliminated Deductions

The tax reform bill of 2017 not only increased the standard deduction, it also eliminated or restricted certain itemized deductions i.e., these expenses used to be deductible if you itemized earlier (pre-2018), but starting with tax year 2018 they are either no longer deductible or have limitations:

List of Restricted Deductions

Eligibility

Standard deductions can be applied only if one is eligible for it. For example, non-resident aliens are not eligible for standard deductions. Added benefits are given for the visually challenged and senior citizens (over 65 years old) in standard deductions, whereas there are no such provisions in itemized deductions.

Restrictions

Itemized deductions impose some restrictions. If you are married and are filing your returns separately, both spouses must make the same choice i.e. you are required to itemize your deductions if your spouse does so. Tax filers are required to maintain records and evidence supporting their itemized deductions. No such substantiation is required for standard deductions.

Utility

Since the standard deduction is based on the filing status, no adjustments can be performed by the IRS until the filing status changes. Therefore if the standard deductions and the itemized deductions amount to the same value, its better to opt for the standard deductions to avoid any adjustments or having to provide proof. However, if you are subject to AMT (alternative minimum tax), you will save more by itemizing rather than opting for standard deductions even if the amount of itemized deductions is low. The reason for this is that standard deductions don't reduce income subject to AMT while some specific categories of itemized deductions can.

How to Itemized Deductions

Itemized deductions require the tax filer to fill and submit Schedule A and the long form 1040. They cannot use 1040EZ. Most online tax preparation services offer free filing for 1040EZ but not for long form 1040.

In addition, tax filers are also required to retain proof such as invoices and payment receipts for the deductions being itemized. There are no such requirements for claiming the standard deduction.
