Line 13

Depreciation and section 179 expense deduction.

Depreciation is the annual deduction allowed to recover the cost or other basis of business or investment property having a useful life substantially beyond the tax year. You can also depreciate improvements made to leased business property. However, stock in trade, inventories, and land are not depreciable. Depreciation starts when you first use the property in your business or for the production of income. It ends when you take the property out of service, deduct all your depreciable cost or other basis, or no longer use the property in your business or for the production of income. You can also elect under section 179 to expense part or all of the cost of certain property you bought in 2025 for use in your business. See the Instructions for Form 4562 and Pub. 946 to figure the amount to enter on line 13.
