What Form 4797 Covers

Form 4797 is the federal form for “Sales of Business Property.” It reports transactions that don’t belong on Schedule D (which handles stocks, bonds, and personal-use property). The types of assets that end up on Form 4797 include:

• Machinery and equipment — a contractor selling a backhoe, a photographer selling camera gear used in their business
• Commercial real estate — selling an office building, warehouse, or retail space
• Rental property — residential rental buildings (though the land and building are split for depreciation purposes)
• Vehicles used in business — a delivery van, a truck used 100% for work
• Section 197 intangibles — patents, copyrights, or goodwill from a business acquisition that you’ve been amortizing

The gain or loss from Form 4797 flows to your federal 1040, and then to IT-201 Line 14. New York follows the federal treatment — there’s no separate state calculation for these gains.

Section 1231 Gains and the Best-of-Both-Worlds Rule

IRC Section 1231 is one of the few tax provisions that genuinely favors the taxpayer. Assets held more than one year and used in a trade or business get Section 1231 treatment when sold. The rule: net gains are taxed as long-term capital gains (lower rates), but net losses are treated as ordinary losses (fully deductible against other income, with no $3,000 cap).

That’s a good deal. Sell a building at a profit? Capital gain rates. Sell equipment at a loss? Ordinary deduction. You get favorable treatment either way. The catch is a 5-year lookback rule — if you had Section 1231 losses in the prior five years, your current gains get recharacterized as ordinary income until those prior losses are “recaptured.” Most people don’t hit this, but it’s worth knowing.

On the IT-201, New York taxes the gain at your ordinary state rate regardless of whether it qualifies for capital gain treatment federally. So the federal benefit of the lower capital gains rate helps on your 1040, but your New York tax doesn’t distinguish. A $100,000 Section 1231 gain hits your IT-201 the same as $100,000 of wages.

Depreciation Recapture: Sections 1245 and 1250

This is where the tax bill gets big. When you depreciate business property — writing off a portion of its cost each year — you’re reducing your taxable income. When you sell that property for more than its depreciated value, the IRS recaptures the depreciation by taxing it as ordinary income. For a deep look at the mechanics, see our depreciation recapture guide.

Section 1245 covers personal property — equipment, vehicles, furniture, computers. All depreciation taken is recaptured as ordinary income, up to the amount of gain. If you bought a $50,000 machine, depreciated it down to $10,000, and sold it for $35,000, you have $25,000 of Section 1245 ordinary income. Not capital gains. Ordinary income, taxed at your full rate.

Section 1250 covers real property — buildings. The rules here are slightly more generous. Only the excess depreciation over straight-line is recaptured as ordinary income. Since most real property uses straight-line depreciation anyway, the recapture under Section 1250 is often zero. But there’s unrecaptured Section 1250 gain, taxed at a maximum 25% federal rate, which still gets taxed at ordinary rates by New York.

A real example: a client sold a commercial building they’d owned for 15 years. The building cost $800,000, and they’d taken $350,000 in depreciation over that period. They sold for $1,200,000. The $350,000 of depreciation recapture alone generated a significant New York tax bill — on top of the capital gain on the remaining profit. People who plan to sell business real estate need to model this out ahead of time, not discover it at tax filing.

When This Line Shows a Loss

Not every Form 4797 transaction is a gain. Businesses that sell equipment for less than its depreciated value have a loss. A restaurant that spent $40,000 on kitchen equipment, depreciated it to $15,000, and sold it for $8,000 has a $7,000 ordinary loss. That loss reduces income on both the federal return and the IT-201.

Casualty and theft losses on business property can also flow through Form 4797. If equipment was destroyed in a fire or stolen, the loss (after insurance) shows up here. These are less common for most filers but can be significant for business owners who experience property damage.

Abandoned property generates losses too. If a business simply writes off an asset — stopped using it and it has no resale value — the remaining undepreciated basis becomes a loss on Form 4797.

Common Mistakes on Line 14

The most frequent error is putting a Form 4797 gain on Line 13 (Capital Gains) instead of Line 14. Schedule D and Form 4797 are different forms, and the IT-201 wants them on different lines. If your gain came from selling stock, it goes on Line 13. If it came from selling business property, it belongs here on Line 14.

Another mistake: forgetting to account for depreciation recapture when estimating the tax cost of a sale. Business owners often focus on the headline sale price and forget that the IRS is going to claw back years of depreciation deductions (IRS Publication 946). On a property you’ve depreciated for 20 years, the recapture amount can be larger than the actual appreciation.

Related IT-201 Lines

Line 14 sits near Line 12 (Business Income) and Line 13 (Capital Gains) in the income section of the IT-201. If you sold rental property, the ongoing rental income before the sale would have been on Line 17. Your Line 14 gain ultimately flows through to Line 37 (Taxable Income) and determines your Line 39 tax amount. For the full walkthrough, return to the IT-201 line-by-line guide.
