Is depreciation good or bad? It’s both, and which side you feel depends on whether you’re deducting an asset’s cost on a tax return or trying to sell that same asset a few years later. On the tax side, depreciation is one of the most powerful deductions available to businesses and rental property owners, and the 2026 rules are unusually generous. On the market side, it’s the steady erosion of what your property is actually worth, and no deduction reverses that loss.
The Tax Side: Depreciation Lowers What You Owe
When you buy equipment, a vehicle, or a building for your business, the IRS generally won’t let you deduct the full cost in the year of purchase. Instead, you recover the cost through annual depreciation deductions spread over the asset’s useful life.1Internal Revenue Service. Topic No. 704, Depreciation Each year’s deduction lowers your taxable income without requiring any new cash outlay. The asset is already earning revenue for you; the tax code just lets you chip away at its cost on paper.
The math is simple. A business earning $300,000 and claiming $50,000 in depreciation pays tax on $250,000. A C-corporation at the flat 21% federal rate saves $10,500 from that one deduction. For a sole proprietor or S-corporation owner, the savings flow to the personal return at the owner’s marginal rate.
Section 179 in 2026
Section 179 lets you expense the full cost of qualifying equipment in the year you place it in service instead of spreading it over years. For tax years beginning in 2026, the limit is $2,560,000, and the deduction phases out dollar-for-dollar once total equipment purchases exceed $4,090,000.2Internal Revenue Service. Rev. Proc. 2025-32 A company spending $6.65 million or more in a single year gets no Section 179 benefit at all, so the provision is aimed squarely at small and mid-sized businesses.
Qualifying property includes machinery, computers, off-the-shelf software, office furniture, and certain building improvements. One catch: the Section 179 deduction can’t exceed your business’s taxable income for the year. If you earned $80,000 and bought $120,000 in equipment, only $80,000 can be expensed now. The remaining $40,000 carries forward.1Internal Revenue Service. Topic No. 704, Depreciation
100% Bonus Depreciation Is Back
Bonus depreciation under Section 168(k) had been phasing down: 80% in 2023, 60% in 2024, and headed toward zero by 2027. The One, Big, Beautiful Bill reversed that. For qualified property acquired after January 19, 2025, bonus depreciation is permanently restored to 100%.3Internal Revenue Service. Treasury, IRS Issue Guidance on the Additional First Year Depreciation Deduction Amended as Part of the One, Big, Beautiful Bill You can deduct the entire cost of eligible new and used assets in the first year, with no dollar cap.
Bonus depreciation also has no taxable-income limitation, so it can create or increase a net operating loss. A business that earns $200,000 and claims $350,000 in bonus depreciation zeroes out its tax bill and generates a $150,000 loss that may be carried forward. Between Section 179 and permanent 100% bonus depreciation, 2026 is one of the most favorable years in memory to buy capital equipment.
Real Estate Depreciation and Paper Losses
Rental property gets its own treatment. Residential buildings are depreciated over 27.5 years, commercial buildings over 39.4Internal Revenue Service. Publication 946 (2025), How To Depreciate Property Only the structure qualifies. You have to subtract the land value from your purchase price first, because land doesn’t wear out and can never be depreciated.
These deductions often create a “paper loss” even when the property produces positive cash flow. Say you collect $24,000 in rent with $16,000 in expenses, leaving $8,000 in net income. If depreciation is $12,000, you report a $4,000 loss on your return while pocketing $8,000 in real cash. That loss can offset other income depending on your participation level and income limits.
The Bad: Recapture Takes Some of It Back at Sale
Depreciation gives on the way in and takes on the way out. When you sell a depreciated asset for more than its adjusted basis (original cost minus depreciation claimed), the IRS wants a piece of that gap back at ordinary income rates rather than the lower capital gains rate.
For most business equipment and vehicles, which fall under Section 1245, the gain attributable to prior depreciation is taxed as ordinary income.5Office of the Law Revision Counsel. 26 USC 1245 – Gain From Dispositions of Certain Depreciable Property A taxpayer in the 32% bracket selling equipment with $40,000 of accumulated depreciation could owe up to $12,800 on the recaptured portion alone.
Real property falls under Section 1250. The portion of the gain traceable to depreciation is taxed as “unrecaptured Section 1250 gain” at a maximum federal rate of 25%. Any gain above the original purchase price is taxed at long-term capital gains rates. A real estate investor who claimed $150,000 in depreciation over the holding period faces up to $37,500 in recapture tax at the 25% ceiling, on top of capital gains tax on any appreciation. This is where depreciation stops looking like free money. A 1031 like-kind exchange can defer recapture on real property by rolling proceeds into a replacement, but it doesn’t erase the obligation permanently.
The Bad: Market Value Drops Whether You Deduct or Not
Tax depreciation is a financial tool. Market depreciation is an economic reality, and it doesn’t consult your tax return. A $50,000 vehicle that loses 20% of its value in the first year has lost $10,000 in equity whether or not you claimed a deduction. The tax benefit softens the blow. It doesn’t prevent the loss.
The pain is worst in the first few years, when values fall fastest. Anyone who financed with a small down payment or a long term can end up “underwater,” owing more on the loan than the asset is worth. A total loss or theft leaves the owner responsible for the shortfall between the insurance payout and the loan balance. Gap insurance exists for exactly this scenario.
For businesses, rapid market depreciation also shrinks the collateral value of equipment pledged against loans, which can limit future borrowing. And when it’s time to replace aging assets, the gap between trade-in value and the price of a replacement often requires a fresh injection of capital. Budgeting for that replacement cycle is unglamorous, and skipping it leads to cash crunches at the worst possible time.
One special wrinkle applies to passenger vehicles. “Luxury auto” caps override normal MACRS and Section 179, limiting first-year depreciation on cars, light trucks, and vans placed in service in 2026 to $20,300 with bonus depreciation or $12,300 without.6Internal Revenue Service. Rev. Proc. 2026-15 These caps stretch a five-year recovery period out to eight or nine years for a typical business truck. Heavy SUVs and trucks with a gross vehicle weight above 6,000 pounds are exempt, which is why so many business buyers gravitate toward full-size pickups.
The Good, If You’re the Second Owner
The flip side of steep early depreciation is that someone else already absorbed those losses. A used buyer can pick up equipment, vehicles, or technology with years of productive life remaining at a fraction of the original price. A $100,000 machine might sell for $60,000 after a few years of light use, giving the second owner the same operational capacity for far less capital.
The advantage compounds because the second owner faces a much flatter market depreciation curve going forward. Most of the value drop has already happened, so the risk of further equity erosion is lower. Lower acquisition cost also means faster breakeven and quicker return on investment.
The tax treatment is generous, too. The IRS recovery period for a used asset starts when the second owner places it in service, not when it was originally manufactured. A three-year-old computer bought used still qualifies for a fresh five-year MACRS schedule in the new owner’s hands, and with 100% bonus depreciation restored, the entire cost can be written off in year one.3Internal Revenue Service. Treasury, IRS Issue Guidance on the Additional First Year Depreciation Deduction Amended as Part of the One, Big, Beautiful Bill Buying used and immediately expensing the purchase is one of the most tax-efficient ways to equip a business.
The Other Depreciation: What Shows Up on Financial Statements
Depreciation on your tax return and depreciation on your financial statements are not the same number. Tax depreciation, driven by MACRS, Section 179, and bonus rules, is designed to encourage investment through accelerated write-offs. Book depreciation follows accounting standards and aims to match an asset’s cost to the revenue it produces over its actual useful life.
That matching keeps a company’s financials from looking artificially profitable in quiet years and unfairly burdened in heavy-purchase years. Straight-line is the most common book method because it produces consistent expense figures and makes year-over-year comparisons more meaningful for lenders and investors.
On the balance sheet, accumulated depreciation reduces the original cost of an asset to arrive at “book value.” When accumulated depreciation is high relative to original cost, it signals to lenders and investors that equipment is aging and replacement is coming. Accurate reporting builds credibility with creditors and forces management to plan for capital expenditures rather than be surprised by them.
So which is it, good or bad? For owners of qualifying business assets in 2026, the tax side is emphatically good and rarely more generous than right now. For anyone counting on resale value, or headed toward a sale of long-depreciated property, the bill comes due. Planning for both sides from the day you buy is what turns depreciation from a surprise into a strategy.
