U.S. Depreciation Rules in 2026: How MACRS and Recovery Periods Impact Nris and H-1B Holders

(U.S.) — U.S. tax rules in 2026 continue to require most owners of business and rental property to recover costs through Depreciation over time, with the Modified Accelerated Cost Recovery System, or MACRS, remaining the standard federal framework for most property placed in service after 1986.

That structure affects NRIs with U.S. rental homes, H-1B professionals running a side business or valid business structure, landlords, self-employed taxpayers, and investors in commercial and residential property. It shapes annual taxable income, future gain calculations and the tax treatment that can follow when property is sold.

Mistakes can be costly. Taxpayers often use the wrong Recovery Periods, choose the wrong system, ignore timing conventions, or assume different types of property receive the same treatment when they do not.

IRS Publication 946 remains the central guide to MACRS Depreciation, and the rules still divide most property between two systems: the General Depreciation System, or GDS, and the Alternative Depreciation System, or ADS. GDS is generally the default, while ADS uses longer recovery periods and straight-line Depreciation and may be required or elected in some cases.

Under GDS, many assets qualify for accelerated write-offs through the 200% declining balance or 150% declining balance method, with a switch to straight-line when that produces a larger deduction. ADS generally uses straight-line over a longer recovery period, producing a slower and more even deduction schedule.

That distinction carries practical consequences. GDS usually delivers larger deductions earlier, lowering current taxable income more quickly, while ADS spreads the benefit across more years. For a business owner, landlord or investor comparing cash flow and future tax expectations, the choice can alter the tax profile of an asset well beyond the year it was purchased.

Election rules also matter. In general, an election to use ADS applies to all property in the same class placed in service during that year, though residential rental property and nonresidential real property have more property-specific treatment. Taxpayers who assume they can change methods casually after filing face a problem because Depreciation methods are not freely changeable without following tax accounting rules.

That makes the initial setup unusually important. The asset class, method, convention and placed-in-service date often determine the deduction pattern from the first year forward.

Recovery Periods remain one of the most practical parts of MACRS because the IRS assigns different classes of property different useful lives for tax purposes. A single taxpayer buying equipment, a building and site improvements in one year can end up with several separate schedules.

Five-year property often includes computers, peripheral equipment, office machinery, certain vehicles, carpeting, appliances, and some machinery or equipment. Seven-year property commonly includes office furniture and fixtures and certain equipment not assigned elsewhere.

Fifteen-year property can include certain land improvements, fences, roads, shrubbery, and qualified improvement property in applicable cases. Twenty-year property can include certain farm buildings and related property classes.

Real estate follows much longer schedules. Residential rental property under GDS is generally depreciated over 27.5 years, while nonresidential real property is generally depreciated over 39 years.

Those different Recovery Periods drive annual deductions. A landlord who buys a residential building, installs appliances and adds fencing may be handling 27.5-year, 5-year and 15-year property at the same time, even though all of it relates to the same investment.

Residential rental property remains one of the categories that taxpayers most often misunderstand. IRS Publication 527 and Publication 946 continue to treat it as 27.5-year property under MACRS, using the straight-line method and the mid-month convention.

The rule applies to the building, not the land. Land is not depreciable, and only the depreciable basis tied to the building and qualifying improvements can be recovered through Depreciation.

That separation is essential when someone buys a rental house or apartment building. The full purchase price cannot be depreciated, so the land value must be carved out first. If the allocation is wrong, the annual deduction can be wrong and the gain calculation later can also be wrong.

Commercial real estate follows a different path. Nonresidential real property, including many office buildings, warehouses, shops and other commercial structures, generally uses 39-year straight-line Depreciation with the mid-month convention.

That longer life means commercial buildings recover cost more slowly than shorter-lived assets such as equipment, furniture or computers. Two investments with a similar purchase price can therefore produce very different tax results depending on whether the dollars are tied up in equipment or in real estate.

Timing conventions are another area where taxpayers often miscalculate first-year deductions. Depreciation depends not only on method and Recovery Periods, but also on the convention that determines when property is treated as placed in service or disposed of for tax purposes.

Publication 946 and Publication 527 continue to apply three main conventions. Residential rental property and nonresidential real property use the mid-month convention. The mid-quarter convention applies in certain cases where more than 40% of the basis of MACRS property placed in service during the year is placed in service in the last three months of the year. Most other MACRS property uses the half-year convention when the mid-quarter and mid-month rules do not apply.

That means a taxpayer who buys an asset late in the year cannot assume a full year of Depreciation automatically follows. The convention controls how much of the first year and final year counts, and that can materially change the deduction.

For many routine business assets, the half-year convention remains the default starting point. Under that rule, property is generally treated as placed in service at the midpoint of the year, so the taxpayer usually gets about half a year of Depreciation in the first year and half a year in the last year, with full-year deductions in the middle years.

That rule often applies to common shorter-life assets such as computers, office furniture, vehicles and equipment. For many small business owners, this is the most familiar MACRS rule, though it can still produce errors when taxpayers overlook the placed-in-service date or the mid-quarter test.

The 2026 rules also include a large Section 179 expensing amount, giving eligible businesses an alternative to recovering cost slowly under ordinary MACRS. IRS Publication 946 states that for tax years beginning in 2026, the maximum Section 179 deduction is $2,560,000.

That amount begins to phase out once the cost of qualifying property placed in service during the year exceeds $4,090,000. The maximum Section 179 deduction for SUVs placed in service in 2026 is $32,000.

For small and mid-sized businesses buying machinery, equipment, software or other qualifying property, those figures can sharply change year-one tax treatment. Section 179 can allow immediate expensing of a large amount, but it operates under its own eligibility and taxable-income limits and is not the same as standard MACRS Depreciation.

Form reporting has also shifted. IRS Instructions for Form 4562 note that for the 2025 tax year, new lines were added to report MACRS depreciation for 50-year property under both GDS and ADS.

That class does not come up often for ordinary small taxpayers, but the change shows that IRS reporting rules continue to evolve. Current-year form instructions still matter even when the broader MACRS structure remains familiar.

The method chosen at the beginning also matters when the property leaves the taxpayer’s hands. Depreciation reduces basis, and that lower basis can affect tax on sale even if the owner has long since stopped thinking about the original deductions.

If the taxpayer claims Depreciation, or even could have claimed it, basis generally falls and later tax consequences can include depreciation recapture or unrecaptured Section 1250 gain. For rental-property owners, that means years of lower taxable income can be followed by a different gain calculation when the asset is sold.

That interaction is one reason Depreciation is more than a bookkeeping exercise. It affects current tax, future basis and the exit calculation at sale.

For NRIs and immigrant taxpayers with U.S. business or rental assets, the practical questions tend to be straightforward but consequential. Was land separated properly from the building. Was the asset classified correctly as 5-year, 7-year, 15-year, 27.5-year, or 39-year property. Was the correct convention applied. Was the asset truly placed in service during the year. Was ADS required or elected correctly. Was Section 179 or another accelerated recovery rule used appropriately.

Each answer can change the size and timing of deductions. In some cases, the difference between GDS and ADS or between a 5-year and 7-year classification affects tax results for years.

For landlords, the most common misunderstandings still center on residential property. A rental building generally belongs on a 27.5-year straight-line schedule under the mid-month convention, while the underlying land does not qualify for Depreciation at all. Improvements and shorter-lived items inside or around the property may follow different Recovery Periods.

For business owners, the challenge often lies in sorting equipment from real estate and matching each item to the right class life and convention. Office furniture and fixtures may fall into 7-year property, while computers and certain vehicles may fall into 5-year property, and land improvements can move into 15-year treatment.

The contrast between those classes helps explain why two taxpayers with the same spending total can show different deductions in the first year. An equipment-heavy investment may recover cost much faster than a real-estate-heavy investment, especially when GDS applies and Section 179 is available.

In 2026, the overall structure has not changed: MACRS remains the main system, GDS usually remains the default, ADS continues to use slower straight-line recovery, and proper results still depend on class life, method, convention and the date property is placed in service.

Residential rental property generally remains 27.5-year property. Nonresidential real property generally remains 39-year property. Many shorter-lived business assets still fall into 5-, 7-, 15-, or 20-year classes.

The standout 2026 update is the size of the Section 179 deduction cap and its phaseout threshold, which make immediate expensing far more relevant for eligible businesses. Even so, the broader lesson remains unchanged: getting the classification right at the beginning is usually far easier than correcting a Depreciation error after several years of returns and a later sale.
