Standard Deduction versus Itemizing
Take the flat amount, or add up the real ones — whichever is bigger.
Every filer subtracts either a flat standard deduction or the total of specific itemized deductions. You pick the larger number. Because the standard deduction is generous, most households never itemize at all.
What to know
- The standard deduction
- A fixed amount set by filing status and adjusted each year for inflation, with extra amounts for taxpayers who are 65 or older or blind.
- What can be itemized
- Mortgage interest, state and local taxes up to a cap, charitable gifts, and medical expenses above a percentage of AGI are the main categories.
- Filing status drives the number
- Single, head of household, and married filing jointly each get different standard amounts, so status is worth checking carefully.
- Bunching
- Pushing two years of charitable gifts or elective medical costs into one year can lift that year over the itemizing threshold while the other year takes the standard deduction.
- Records only matter if you itemize
- Receipts and acknowledgment letters are required to support itemized amounts; the standard deduction needs no proof.
The tax benefit
Choosing correctly, and timing deductible spending, can save hundreds or thousands without changing what you actually spend over two years.
Worked example
Bunching two years of giving
A couple normally gives $8,000 a year and falls just under the standard deduction. Giving $16,000 in one year and nothing the next lets them itemize once and take the standard deduction the other year.
Watch out for
- State and local tax deductions are capped, which keeps many high-tax-state filers on the standard deduction.
- Charitable gifts need written acknowledgment above modest amounts.
- Some states require you to itemize federally to itemize on the state return.
