Suppose your available standard deduction is $16,100 and your allowable itemized deductions total $20,000. Itemizing would reduce taxable income by an additional $3,900.

At an assumed 22% marginal rate, that difference illustrates $858 of federal income-tax reduction if the entire difference falls in that bracket. Actual savings depend on your complete return; the $20,000 is not your refund.

Your next steps

• Use your actual filing status and deduction.
• Calculate allowable expenses after limits.
• Compare the tax result rather than only the deduction total.
