Itemized deductions and Schedule A: records to prepare
Updated: 2026
Itemizing is not automatically better than taking the standard deduction. Schedule A is used when eligible itemized deductions are relevant, so the useful first step is to collect the records that allow both approaches to be compared.
What Schedule A can include
Schedule A can include eligible medical and dental expenses, certain state and local taxes, qualified interest, charitable contributions, and some other deductions. Each category has its own rules and limitations.
Do not move an expense to Schedule A simply because it was paid during the year. Some expenses belong elsewhere on the return, and some are not deductible.
Records worth gathering
Bring mortgage-interest statements, property-tax records, receipts or acknowledgments for charitable contributions, and records of potentially deductible medical expenses when those items are relevant to your situation.
For state and local taxes, keep the underlying tax documents and payment records. For charitable gifts other than cash, keep the documentation that describes the donated property and supports the amount claimed.
Standard deduction versus itemizing
In most cases, the federal return uses whichever permitted approach produces the larger deduction: the standard deduction or total allowable itemized deductions. The comparison depends on filing status, the tax year, and the deductions actually allowed.
This is why it can still be useful to provide Schedule A records even when you are not sure that itemizing will be used.
Facts to flag before preparation
Mention unusually large medical costs, major charitable gifts, a home purchase or refinance, more than one home, taxes paid in more than one state, or married-filing-separately circumstances. Those facts can change which records and limitations need review.
