Itemize vs Standard

Itemized vs Standard Deduction — Which Tax Path Wins?

Same as our standard-vs-itemized comparison: about 87% of filers take the standard deduction. The remaining 13% have enough mortgage interest + state tax to beat it.

Verdict

Standard deduction wins for renters, low-mortgage homeowners, and anyone in no-income-tax states. Itemize when SALT ($10K cap) + mortgage interest + charity > $14,600 (single) / $29,200 (married).
