A new roof on a business building belongs on Form 4562, form 4562, carried to schedule c line 13.
Why form 4562
Replacing a roof restores a building system, so it is capitalised and depreciated rather than deducted on line 21. Nonresidential real property is recovered over 39 years under the general depreciation system, so a roof put on this year gives you a modest annual deduction, not a large current one. Patching a section of the same roof is the opposite answer: that keeps the building in ordinary efficient operating condition and stays on line 21.
Stop looking up lines one at a time. ClaryBook totals your year into an IRS Schedule C worksheet in form order, Part I and Part II line by line, so a new roof on a business building lands on Line 4562 without you sorting it.
Start for freeWhat a new roof on a business building is confused with
- Line 21, repairs and maintenance
- Patching a leak or replacing a few shingles is line 21, while replacing the roof is a restoration and is capitalised.
- Line 30, line 30, business use of your home
- A new roof on a home with an office in it is capitalised and recovered through the home office calculation on line 30, not deducted in full.
- Line 13, depreciation and section 179 expense deduction
- The roof never shows as its own expense line: it is an asset on Form 4562 whose depreciation or section 179 amount joins the line 13 total.
Examples that belong on form 4562
- A $28,000 roof replacement on a workshop you own and use for the business
- A $14,500 flat roof replacement on a retail unit
- A $40,000 roof and parapet rebuild on a small warehouse
- A $9,000 partial roof replacement over one section of a building
- A $650 shingle patch on the same roof, which stays on line 21
What does not belong here
- A full line 21 deduction in the year of payment.
- Patch repairs rolled into the capitalised amount when they were billed separately.
- A roof on a rental property you do not use in your trade, which belongs on Schedule E.
- A roof on your home deducted in full because you have a home office.
The limit that applies
A roof on nonresidential real property can be eligible for the section 179 deduction, which is an election on Form 4562 rather than a different Schedule C line. The annual section 179 limit is set each year.
What to keep
Keep the roofing contract and invoice, the date the work was completed, photographs before and after, and the building's cost basis file. The invoice has to make clear whether the roof was replaced or repaired.
