You claim these by filing Schedule A with your tax return to reduce your taxable income.

What does the IRS allow you to deduct (or “write off”) without receipts?
Itemized deductions are expenses that you can subtract from your adjusted gross income, reducing the amount of tax you owe. These deductions cover various expenses throughout the year, such as medical expenses, mortgage interest, and charitable contributions.
