With 2025 in the rear view mirror and the tax filing deadline on the road ahead, it’s a good time for businesses to start gathering information about their deductible expenses for 2025. But what’s deductible (and what’s not) might not be as clear-cut as you think. Most business deductions aren’t specifically listed in the Internal Revenue Code (IRC). The general rule is what’s stated in the first sentence of IRC Section 162, that you can write off “all the ordinary and necessary expenses paid or incurred during the taxable year in carrying on any trade or business.” In addition, you must be able to substantiate the expenses. We can help you determine what you can deduct on your 2025 tax return.
