What Form 4562 is and when it’s used

Form 4562 is the IRS form used to report depreciation, amortization, and Section 179 expensing for business property and placed-in-service assets. Taxpayers use it to claim MACRS depreciation, bonus (special) depreciation, cost recovery for listed property, and amortizable intangible assets. Individuals, partnerships, corporations, S corporations, and estates include Form 4562 with the applicable income tax return for the year an asset is placed in service or when a Section 179 election is made.

Why completing Form 4562 matters for tax reporting

Accurate completion preserves tax benefits and supports deductions that lower taxable income; it documents cost basis, placed-in-service dates, and elected deductions such as Section 179 or bonus depreciation. Proper filing reduces audit risk and provides the IRS with the details needed to substantiate depreciation claims on the related return.
