FAQ

Should I itemize instead of taking the standard deduction?

Itemizing only makes sense if your eligible itemized deductions are higher than the standard deduction. Use the Itemized vs Standard tool (coming soon).

What if I’m claimed as a dependent?

Dependents may have a limited standard deduction based on earned income. Add the dependent rule section to this page for accuracy.

Do I get more standard deduction if I’m 65+?

Often yes — many filers qualify for an additional standard deduction if age 65+ and/or blind (amount depends on filing status).

Does the standard deduction reduce AGI?

No — it reduces **taxable income**, not AGI.

Can I take the standard deduction if I own a home?

Yes. Home ownership doesn’t force itemizing; it just may increase itemized deductions for some filers.

Does this include state taxes?

No — states have their own rules.

Married filing separately: any special rules?

Yes, and itemizing can interact with MFS. If you itemize, your spouse often must itemize too.

Is this calculator official IRS guidance?

No — it’s an estimator. Always confirm numbers against the IRS for filing.
