A married couple's itemized deductions each year are about $30,000, just under their standard deduction. Which strategy may lower their total tax over two years?
Bunching deductible payments such as charitable gifts (for example through a donor-advised fund) into one year can push itemized deductions well above the $31,500 joint standard deduction for 2025 that year, while taking the standard deduction the next. Filing separately does not help, because if one spouse itemizes the other must too. Source: IRC 63(b)-(c), 170; Pub. 526 (2025); 2025 Form 1040 instructions. Tax year: 2025 (law as of 31 Dec 2025).
Assuming deductions are worth the same whenever they are paid.
