Standard vs Itemized Deduction

Compare the standard and itemized deductions — when does it make sense to itemize?

Overview

The standard deduction is a fixed amount everyone can take ($15,000 single / $30,000 married for 2025). Itemized deductions are specific expenses like mortgage interest, state and local taxes, and charity. You take the larger of the two — and after the 2017 tax law, the standard wins for ~90% of filers.

Choose Standard Deduction when...

Take the standard deduction unless you have substantial mortgage interest, state taxes, or charitable contributions that clearly exceed it.

Choose Itemized Deduction when...

Itemize when your deductible expenses exceed the standard deduction — typically homeowners with mortgages and significant charity in high-tax states.

Our Verdict

For most filers — about 90% — the standard deduction wins after the 2017 tax law nearly doubled it. Itemizing makes sense if your deductible expenses (mortgage interest + state and local tax up to $10K + charity + medical above 7.5% AGI) exceed the standard deduction. Bunch charitable giving into single years to clear the standard deduction in alternate years.
