Bonus depreciation 2026 guide for business owners

If your business is planning a major equipment purchase in 2026, the clock is running. Bonus depreciation has declined every year since the Tax Cuts and Jobs Act began its phase-down, and 2026 marks the final year any immediate percentage deduction is available before the provision expires. At 20%, the deduction still generates real, measurable savings on qualifying business assets, and understanding how to use it before December 31 can mean the difference between capturing a significant tax benefit or losing it permanently.

Depreciation and amortization are among the most effective tools available to business owners, and bonus depreciation is their most aggressive form. When applied correctly, it reduces taxable income in the year equipment is placed in service, rather than spreading cost recovery across multiple years. This guide explains the 20% rate in plain terms, shows how to calculate your actual savings, and outlines the strategies that produce the best results when coordinated with other deductions.

Businesses that also claim Vehicle expenses for qualifying business vehicles should take note, as those purchases are subject to the same 2026 deadline and can be part of a coordinated year-end tax strategy.

Why 2026 is the final year for bonus depreciation

The Tax Cuts and Jobs Act introduced 100% bonus depreciation in 2017, allowing businesses to deduct the entire cost of qualifying property in the year of purchase. That rate has followed a fixed phase-down schedule ever since:

1. 100% for assets placed in service through December 31, 2022
2. 80% for assets placed in service in 2023
3. 60% for assets placed in service in 2024
4. 40% for assets placed in service in 2025
5. 20% for assets placed in service in 2026

0% for assets placed in service after December 31, 2026, unless Congress acts.

That final point deserves emphasis. Without new legislation, every dollar of bonus depreciation not claimed in 2026 is permanently lost. Business owners who have been deferring equipment purchases face a concrete and final deadline. The 20% rate is modest compared to earlier years. However, on a $500,000 purchase, it still generates a $100,000 immediate deduction, which translates to $37,000 in federal tax savings for a business owner in the top 37% bracket.

Full details on qualifying asset classes, MACRS recovery periods, and depreciation conventions can be found in IRS Publication 946, the authoritative guide to depreciating business property.

What is bonus depreciation and how does it work in 2026

Bonus depreciation is a first-year deduction that applies in addition to regular MACRS depreciation. It allows businesses to write off a set percentage of an asset's full cost basis immediately, in the year the property is placed in service. The 2026 rate of 20% means one-fifth of the cost of each qualifying asset is deducted upfront, with the remaining 80% depreciated over the asset's standard recovery period.

The mechanics follow a straightforward sequence:

• Confirm the asset qualifies based on recovery period, business use, and taxpayer eligibility
• Establish the full depreciable cost basis, which includes the purchase price plus any capitalized acquisition costs
• Multiply the cost basis by 20% and deduct that amount in 2026
• Depreciate the remaining 80% of the basis using the applicable MACRS method over the normal recovery period for that asset class
• Report all depreciation on Form 4562, Depreciation and Amortization, which must be attached to the federal return for any year in which qualifying property is placed in service

One important distinction separates bonus depreciation from Section 179 expense. Bonus depreciation carries no income limitation and can create or increase a net operating loss. Under the Tax Cuts and Jobs Act, NOLs carry forward indefinitely but are limited to offsetting 80% of taxable income in any future year. For businesses with limited or variable income, this carry-forward feature provides a deferred value even when current-year income is not sufficient to absorb the full deduction.

What assets qualify for 20% bonus depreciation in 2026

Not every business asset is eligible. To qualify for bonus depreciation, property must have a MACRS recovery period of 20 years or less, must be placed in service during the applicable tax year, and must be new to the taxpayer. Eligible categories for 2026 include:

1. Machinery, production equipment, and manufacturing tools
2. Computers, servers, and business technology hardware
3. Furniture, fixtures, and office equipment
4. Off-the-shelf business software
5. Business vehicles with a gross vehicle weight rating over 6,000 pounds

Qualified improvement property (QIP) also qualifies, covering eligible interior improvements to existing nonresidential buildings. Following the CARES Act correction that assigned a 15-year recovery period to QIP, these interior improvements to nonresidential buildings now qualify for bonus depreciation. If your business is renovating a commercial workspace, upgrading a retail location, or reconfiguring an office interior, those costs meet the eligibility threshold.

For assets used partly for business and partly for personal purposes, only the business-use portion qualifies, and that percentage must be documented throughout the year. The same documentation discipline that supports Home office deductions applies here. Pairing equipment depreciation records with Meals deductions and Travel expenses tracking creates an organized, audit-ready business expense record across multiple deduction categories.

How to calculate your 2026 bonus depreciation tax savings

Understanding the mechanics is straightforward once you know your asset cost and marginal tax rate. The following examples show how the 20% deduction translates to real dollars across different business sizes.

Example 1: Manufacturing company, C Corporation

• Qualifying equipment placed in service in 2026: $400,000
• Bonus depreciation deduction (20%): $80,000
• Remaining basis depreciated under MACRS over 5 years: $320,000
• Corporate tax rate: 21%
• Immediate federal tax savings from bonus depreciation: $16,800

Example 2: Pass-through entity owner

• Qualifying equipment and QIP placed in service: $750,000
• Bonus depreciation deduction (20%): $150,000
• Owner's marginal individual tax rate: 37%
• Immediate federal tax savings from bonus depreciation: $55,500

Example 3: Large equipment acquisition with Section 179 layered in

• Total qualifying purchases: $2.0 million
• Section 179 deduction applied first (up to taxable income): $600,000
• Bonus depreciation on remaining basis (20% of $1.4 million): $280,000
• Combined first-year deduction: $880,000
• Total remaining MACRS basis to depreciate over future years: $1.12 million

These examples illustrate why coordinating both deductions in a single year often produces the best outcome. Even at 20%, layering bonus depreciation on top of Section 179 can push first-year deductions well beyond what either method alone provides.

How to combine Section 179 with bonus depreciation

The most efficient approach for many businesses is to use Section 179 and bonus depreciation together, rather than relying on a single method. Under the One Big Beautiful Bill Act, the statutory Section 179 annual deduction limit increased to $2.5 million, with a phase-out beginning at $4 million in total qualifying purchases; due to inflation indexing, the actual limits for 2026 are slightly higher than these base amounts. This expansion significantly widens immediate expensing options for qualifying property placed in service in 2026.

When applying both methods in the same year, use this sequence:

1. Apply Section 179 first, up to the applicable annual limit and further capped by your net business taxable income, to fully expense the highest-priority assets
2. Apply 20% bonus depreciation to any remaining basis in eligible property that was not fully expensed under Section 179
3. Depreciate the remaining 80% of the bonus-eligible basis over the property's regular MACRS recovery period
4. Confirm that your elected Section 179 deduction does not exceed taxable income for the year, while recognizing that bonus depreciation is not subject to an income limitation and can create or increase a net operating loss

For S Corporations, the Section 179 deduction passes through to shareholders, and the taxable income limitation is applied at the individual level. This adds complexity when multiple owners hold different ownership percentages. Businesses already operating as S Corporations should model both deductions against their projected pass-through income before finalizing purchase timing.

Business owners weighing structural changes should also evaluate entity elections before year-end. Late S Corporation elections affect how depreciation deductions flow to individual owners, and coordinating that decision alongside a major equipment purchase in 2026 can produce significantly different tax outcomes than making either decision in isolation.

When should you buy equipment to capture the 2026 deduction

Equipment must be placed in service, not merely ordered, contracted, or invoiced, by December 31, 2026. An asset sitting uninstalled in a warehouse does not meet the placed-in-service standard regardless of the purchase date. Carefully planning the acquisition timeline is essential.

Several practical steps help maximize the remaining window:

• Place orders early enough to guarantee delivery, installation, and operational readiness before year-end, allowing buffer time for shipping delays or contractor scheduling
• Coordinate large purchases with your highest-income quarters so the deduction offsets peak taxable income in the same tax year
• Consider financing equipment purchases; the immediate tax deduction is available even when assets are financed, making cash flow preservation compatible with capturing the benefit
• Stack multiple deductions together by pairing bonus depreciation with Traditional 401k contributions and Health reimbursement arrangement funding to compound total tax reduction in a single year

For businesses with volatile income, placing major equipment purchases in a high-income year ensures the deduction is applied against income that would otherwise face the highest marginal rates, maximizing the effective benefit per dollar spent.

What states conform to the federal bonus depreciation rules

Federal bonus depreciation rates do not automatically apply at the state level. Many states have decoupled from the federal schedule and imposed their own depreciation rules, which can significantly affect your total tax savings calculation when both federal and state income taxes are considered.

States that do not conform to federal bonus depreciation typically require businesses to use regular MACRS schedules for state purposes, which means the state deduction is smaller in the early years and larger in later years. States that conform fully allow the same 20% first-year deduction on the state return. A few states provide partial conformity or impose separate dollar caps.

High-tax states with partial or non-conforming bonus depreciation rules include California, New York, New Jersey, and Illinois. If your business operates or files in any of these states, the effective federal-plus-state savings from bonus depreciation will be lower than the federal calculation alone suggests.

Before finalizing any large equipment purchase decision based on projected tax savings, confirm your state's current depreciation conformity position with a tax professional. The State Tax Deadlines page provides a current reference for state-level tax rules and filing requirements across all 50 states.

What records do you need to claim bonus depreciation

Clean documentation is what separates a sustainable deduction from one that gets reversed on examination. These are the records that matter for each qualifying asset:

1. A purchase invoice or sales contract showing total cost, asset description, and the date of the transaction
2. Proof of payment through a bank statement, wire confirmation, ACH record, or cancelled check
3. Evidence that the asset was placed in service in 2026, such as a signed installation record, delivery acceptance confirmation, or a dated photograph showing the asset in operational use
4. Business-use percentage documentation for any asset used for both business and personal purposes, which the IRS requires for listed property
5. Asset identification data, including serial numbers, model numbers, or other identifiers, particularly for vehicles and technology equipment subject to listed property rules

All bonus depreciation must be reported on Form 4562, Depreciation and Amortization, filed with the federal income tax return for every year in which qualifying property is placed in service. Partnerships and S Corporations report depreciation at the entity level and pass it through to individual owners on Schedule K-1. Retain all documentation for at least three years after the return is filed, and longer for assets that remain on a MACRS depreciation schedule where recapture rules could apply upon eventual sale.

Frequently asked questions

Q: Is 2026 really the last year to claim any bonus depreciation?

A: Under current law, yes. The rate is 20% in 2026 and falls to zero starting January 1, 2027, unless Congress passes legislation to extend or restore the provision. Equipment must be purchased and placed in service on or before December 31, 2026, to lock in the deduction before it expires.

Q: Can bonus depreciation create a net operating loss?

A: Yes, and this is one of its most powerful advantages over Section 179. Bonus depreciation is not limited by your business's taxable income for the year. If the deduction exceeds current net business income, the excess becomes a net operating loss. Under the Tax Cuts and Jobs Act rules, NOLs carry forward indefinitely, though they are generally limited to offsetting 80% of taxable income in any future year.

Q: Does used equipment qualify for the 20% bonus depreciation in 2026?

A: Yes. Used property has qualified since the Tax Cuts and Jobs Act expanded eligibility in 2017. The key requirement is that the property must be new to the taxpayer, meaning you have not previously used, owned, or had a depreciable interest in that specific asset. Prior MACRS depreciation by a different owner does not disqualify the equipment from being considered used.

Q: How does the 20% deduction interact with regular MACRS depreciation?

A: Bonus depreciation covers 20% of the asset's full cost basis in year one. The remaining 80% is then depreciated over the standard MACRS recovery period for that asset class using the applicable method. For example, a five-year property would have its remaining 80% basis depreciated under the 200% declining-balance method over five years, as if no bonus depreciation had been applied to the full original basis.

Q: Are passenger vehicles subject to different limits for bonus depreciation?

A: Yes. Passenger vehicles weighing 6,000 pounds or less are subject to annual luxury auto depreciation caps, even when bonus depreciation applies. For 2026, these caps limit total first-year depreciation on qualifying passenger vehicles to specific IRS-published dollar amounts. Vehicles with a gross vehicle weight rating over 6,000 pounds are not subject to these caps and receive the full 20% bonus depreciation within standard rules.

Q: Can S Corporations and Partnerships claim bonus depreciation?

A: Yes. Both entity types claim bonus depreciation at the entity level, and the deduction passes through to individual partners or shareholders via Schedule K-1. Individual owners then apply their allocated share to their personal returns, subject to applicable passive activity and at-risk rules that may limit the amount that can be deducted in a given year.
