How Long to Depreciate Parking Lot Paving: 15 Years and Bonus

Parking lot paving is depreciated over 15 years under federal tax rules, but most businesses placing a new lot in service in 2026 can deduct the entire cost in the first year through 100% bonus depreciation. The IRS classifies paving as a land improvement, which puts it on a 15-year recovery schedule under the Modified Accelerated Cost Recovery System (MACRS).¹ Before you run any depreciation at all, check whether what you spent is actually a capital improvement or a repair you can deduct this year.

Why Paving Falls on the 15-Year Schedule

Land itself is never depreciable, but improvements to it are. The IRS treats parking lot paving, along with roads, sidewalks, fences, and landscaping, as land improvements under MACRS asset class 00.3.¹ Under the General Depreciation System (GDS), the default for most taxpayers, land improvements carry a 15-year recovery period. Because of the half-year convention, the cost actually stretches across 16 calendar years.

A slower schedule applies in one common situation. The Alternative Depreciation System (ADS) uses straight-line depreciation over 20 years for land improvements.¹ A real property trade or business that elects out of the business interest deduction limitation under IRC Section 163(j) must use ADS for all of its property, so paving goes from 15 years to 20. Worth modeling before you make that interest election.

100% Bonus Depreciation for Paving Placed in Service in 2026

For most 2026 projects, the 15-year schedule is academic. The One, Big, Beautiful Bill Act permanently restored 100% bonus depreciation for qualified property acquired after January 19, 2025.² All 15-year MACRS property qualifies, so parking lot paving is in. There is no dollar cap.

What counts is the acquisition date, not the day paving crews finish. The IRS looks at when a binding written contract was signed. If that date falls after January 19, 2025, 100% of the cost is deductible in the year the lot is placed in service.² Any project contracted in 2025 or 2026 is straightforward.

Paving contracted before January 20, 2025, but placed in service in 2026, is a different story. That property falls under the pre-OBBB phase-down, which allows only 20% bonus depreciation for 2026 placements. The remaining 80% is recovered over the standard 15-year MACRS schedule. If you signed a contract in late 2024, the few weeks on either side of January 20 can mean the difference between a full first-year deduction and spreading most of the cost across 16 years.

You can also elect out of bonus depreciation entirely. Some businesses want deductions spread across years to match expected income or future rate changes. The election is made class by class, so opting out for 15-year property does not touch your equipment deductions.

Section 179 Will Not Cover Parking Lot Paving

Section 179 expensing comes up constantly alongside bonus depreciation, so it is worth stating clearly: it does not apply here. Section 179 is limited to Section 1245 property (essentially tangible personal property) and a narrow list of “qualified real property,” which covers interior improvements to nonresidential buildings, roofs, HVAC, fire protection, and security systems.³ Parking lot paving is an exterior land improvement classified as Section 1250 property. It fits neither category. Bonus depreciation is the vehicle for accelerating paving costs.

Calculating the Deduction When You Don’t Take Bonus

If you skip bonus depreciation or are stuck with the old phase-down, the depreciable basis is recovered over 15 years using the 150% declining balance method under GDS.¹ This front-loads the deductions. The IRS applies a fixed rate to the remaining undepreciated balance each year and automatically switches to straight-line in whichever year straight-line gives a larger write-off.

Timing is governed by the half-year convention. The lot is treated as placed in service at the midpoint of the year regardless of the actual date, which produces a half-year of depreciation in year one and a half-year in year 16.¹ Using the IRS tables in Publication 946, the first-year deduction under 150% declining balance with the half-year convention works out to 5% of the depreciable basis. The percentage climbs in years two and three before gradually declining.

A less generous rule, the mid-quarter convention, applies if more than 40% of all MACRS property placed in service during the year came in during the last three months.¹ Businesses paving late in the year should check that their earlier-year asset purchases give enough of a cushion. Everything is reported on IRS Form 4562.⁴

Repair or Capital Improvement?

Not every parking lot expense needs to be depreciated at all. Routine upkeep that keeps the lot functional without making it substantially better is a current-year deduction under IRC Section 162. The IRS Tangible Property Regulations apply three tests, often called the BAR framework: does the work result in a betterment, an adaptation to a new use, or a restoration?⁵ A yes to any of them means capitalize. All no’s means deduct now.

The unit of property is the paved area itself, analyzed separately from the building it serves. Filling potholes, sealing cracks, and sealcoating over the existing surface are classic repairs. Full-depth asphalt replacement, milling and resurfacing, and expanding the lot’s footprint are improvements. A complete resurface restores the lot to like-new condition (restoration); adding square footage is a betterment. Those costs enter the 15-year pipeline or qualify for bonus depreciation.

Routine Maintenance Safe Harbor

Recurring paving work gets its own protection. If the activities are ones you reasonably expect to perform more than once during the property’s class life, and the purpose is keeping the lot in ordinarily efficient operating condition, the costs are deductible.⁵ The class life for land improvements is 20 years. Sealcoating every four or five years fits easily, because you will clearly do it multiple times across two decades.

Safe Harbor for Small Taxpayers

Smaller owners have another option. The safe harbor for small taxpayers lets you deduct the full cost of repairs, maintenance, and even improvements to a building if three conditions are met: average annual gross receipts of $10 million or less over the prior three years, an unadjusted building basis of $1 million or less, and total annual repair and improvement costs for that building no greater than the lesser of $10,000 or 2% of the building’s unadjusted basis.⁵ The election is annual on a timely filed return. For a retail building with a $400,000 basis, the cap would be $8,000, meaning a modest paving patch under that figure could be expensed even if it would otherwise be an improvement.

De Minimis Safe Harbor

The de minimis safe harbor allows immediate expensing per item or per invoice up to $5,000 if you have audited financial statements, or $2,500 if you do not.⁵ A full paving job will blow through these numbers. It can still help with small ancillary billings like parking bumpers or signage that come in under the per-invoice limit.

Claiming a Loss on Pavement You Tear Out

When old asphalt is removed and replaced, the undepreciated cost of the old surface is still on your books. Do nothing and it stays there, giving you no benefit for the retirement. The partial disposition election under Treasury Regulation 1.168(i)-8 lets you recognize a loss on the removed portion in the year it comes out.⁶

Figure out the adjusted basis of the old pavement at the time of removal: original cost minus depreciation already claimed. The remainder is your deductible loss. No special form; you make the election by reporting the loss on a timely filed return including extensions. It is easy to miss, and it leaves real money behind, especially on lots paved recently with substantial basis remaining.

A related question is whether the cost to physically rip out the old asphalt has to be capitalized into the land. IRC Section 280B requires demolition costs for “structures” to be added to the land’s basis, but the regulations define “structure” as a building, not pavement or other land improvements.⁷ Removal costs are generally included in the new improvement’s depreciable basis or deducted as part of the disposition, not trapped in non-depreciable land.
