When filing a federal income tax return, taxpayers generally have a choice between taking the standard deduction or itemizing their deductions. The choice can affect how much of your income is subject to federal income tax, so understanding how both options work can help you determine which may provide the greater tax benefit.
For 2026, the standard deduction amounts have increased, while changes under the One Big Beautiful Bill Act (OBBBA) have also affected certain itemized deductions. For some taxpayers, taking the standard deduction may be the simplest and most beneficial option. Others may save more by adding up eligible expenses and itemizing.
There is no single answer that works for everyone. Your filing status, income, expenses, homeownership, charitable contributions, medical expenses, and state and local taxes can all affect which deduction is more valuable.
What Are Itemized Deductions?
Itemized deductions are qualifying expenses that taxpayers can report individually on Schedule A of Form 1040 to reduce their taxable income.
Instead of taking one predetermined deduction amount, taxpayers who itemize add together eligible expenses and deduct the total from their adjusted gross income.
Common itemized deductions can include:
- Certain state and local taxes
- Mortgage interest
- Charitable contributions
- Certain medical and dental expenses
- Certain casualty and theft losses
- Certain other qualifying expenses
Not every expense is deductible, and many itemized deductions have specific limitations. Taxpayers should review the current IRS rules before assuming an expense qualifies.
Itemizing may make sense when the total of your eligible deductions is greater than the standard deduction available for your filing status.
How Does Itemized Deductions Work?
The process of itemizing generally begins by identifying all qualifying expenses paid during the tax year.
For example, suppose a married couple filing jointly has the following potentially deductible expenses in 2026:
- $18,000 in qualifying state and local taxes
- $12,000 in mortgage interest
- $8,000 in qualifying charitable contributions
- $5,000 in qualifying medical expenses
The couple would then determine how much of those expenses can actually be deducted under the applicable tax rules and limitations.
If their total allowable itemized deductions exceed the standard deduction for married couples filing jointly, itemizing could potentially reduce their taxable income more than taking the standard deduction.
However, taxpayers should not assume that every dollar spent automatically becomes a dollar of itemized deductions. Certain deductions are subject to thresholds, caps, or other restrictions.
For example, medical expenses are generally deductible only to the extent that qualifying expenses exceed 7.5% of adjusted gross income.
What Is a Standard Deduction?
The standard deduction is a fixed amount that taxpayers can generally subtract from their income when determining taxable income.
Unlike itemized deductions, the standard deduction does not require taxpayers to calculate individual qualifying expenses on Schedule A.
For 2026, the standard deduction is (IRS Revenue Procedure 2025-32):
- $16,100 for single taxpayers and married taxpayers filing separately
- $24,150 for heads of household
- $32,200 for married couples filing jointly and qualifying surviving spouses
Additional standard deduction amounts may be available to taxpayers who are age 65 or older or blind. The standard deduction is designed to simplify tax filing by allowing eligible taxpayers to reduce their taxable income without documenting a large list of individual expenses.
How Does the Standard Deduction Work?
The standard deduction reduces taxable income before federal income tax is calculated. For example, suppose a single taxpayer has $70,000 in adjusted gross income and qualifies for the $16,100 standard deduction in 2026.
The taxpayer could potentially reduce taxable income to $53,900 before accounting for other applicable adjustments or deductions.
The standard deduction does not reduce your tax bill by the deduction amount. Instead, it reduces the amount of income subject to federal income tax.
For many taxpayers, the standard deduction is attractive because it is straightforward. There is no need to calculate mortgage interest, charitable donations, state and local taxes, or other itemized expenses if the standard deduction provides the larger benefit.
Standard Deduction vs. Itemized Deductions in 2026
The best choice generally depends on which deduction produces the greater reduction in taxable income.
For taxpayers with relatively few deductible expenses, the standard deduction may be the better option. Homeowners with significant mortgage interest and property taxes, taxpayers who make substantial charitable donations, and individuals with other qualifying expenses may find that itemizing provides a larger deduction.
The 2026 SALT changes are also relevant. Under the OBBBA, the federal deduction limit for qualifying state and local taxes increases to $40,400 for most taxpayers in 2026, up from $40,000 in 2025. However, higher-income taxpayers may be subject to a phaseout.
This change could make itemizing more attractive for some taxpayers who pay substantial state and local taxes.
What Is the Difference Between Standard and Itemized Deduction?
The primary difference is how the deduction is calculated. The standard deduction provides a predetermined amount based on your filing status. Itemized deductions require you to calculate and document qualifying expenses individually.
For example, a single taxpayer may receive a $16,100 standard deduction in 2026. If that taxpayer has $20,000 in allowable itemized deductions, itemizing could potentially provide the larger tax benefit.
On the other hand, if the taxpayer has only $10,000 in allowable itemized deductions, taking the $16,100 standard deduction would generally provide the larger deduction.
Taxpayers generally cannot claim both the standard deduction and itemized deductions on the same federal income tax return.
Who Should Consider Itemizing?
Itemizing may be worth considering if you have significant qualifying expenses. You may want to compare your itemized deductions with the standard deduction if you own a home, make significant charitable contributions, pay substantial state and local taxes, or have notable medical expenses. For example, homeowners may benefit from deducting mortgage interest and certain property taxes, while taxpayers who give generously to qualified charities may find those contributions increase their total deductions enough to make itemizing worthwhile. Similarly, individuals who pay higher state, local, or property taxes may see added value in itemizing, especially with the updated 2026 SALT limit. In some cases, taxpayers with significant unreimbursed medical and dental expenses may also benefit, provided those costs exceed the applicable income threshold for deduction eligibility.
Who May Benefit From the Standard Deduction?
The standard deduction may be especially beneficial for taxpayers who do not have enough qualifying expenses to exceed the standard deduction. It can also be a convenient option for taxpayers who want a simpler filing process.
For example, a renter with relatively few deductible expenses may have little reason to itemize. If their total allowable itemized deductions are significantly lower than the standard deduction, choosing the standard deduction would generally result in a larger deduction. Taxpayers should still compare both options before filing rather than automatically choosing one.
How to Choose Between the Two
Start by determining your standard deduction based on your filing status and circumstances. Next, calculate your potential itemized deductions. Gather documentation for mortgage interest, charitable contributions, qualifying taxes, medical expenses, and other potentially deductible expenses. Then compare the two amounts.
If your itemized deductions are higher than your standard deduction, itemizing may provide the greater tax benefit. If your standard deduction is higher, taking it may be the better choice.
Tax software can generally calculate both options automatically, but taxpayers with complicated financial situations may benefit from speaking with a tax professional.
