Section 179 Deduction FAQs (2026)

Section 179 lets an eligible business elect to expense (deduct) some or all of the cost of qualifying equipment, software, and certain other property in the year it’s placed in service—up to annual dollar limits and subject to a taxable income limitation. Listed property (such as vehicles) must generally be used more than 50% for business to qualify. This can reduce current-year taxable income and may improve cash flow compared to depreciating the asset over several years.

For tax years beginning in 2026, the maximum Section 179 deduction is $2,560,000. The deduction begins to phase out when the total cost of qualifying property placed in service exceeds $4,090,000; each dollar over that threshold reduces the available deduction dollar-for-dollar (fully phased out at $6,650,000). These limits are adjusted annually for inflation.

Note: Special rules and caps may apply to certain vehicles. For example, certain SUVs have a separate, lower Section 179 cap (see below).

For current-year details and examples, see our Section 179 Deduction page. For background on recent legislative changes and effective dates, see our Legislative History page.

Yes. Section 179 is a permanent tax code provision that allows annual deductions for qualifying property placed in service by the end of your tax year. However, annual dollar limits, a phase-out threshold, and a taxable income limitation apply, so it’s important to consult a tax professional to optimize your yearly strategy.

Many business vehicles, including certain SUVs, pickup trucks, and vans, can qualify if used more than 50% for business. However, different rules apply: some vocational or non-personal-use vehicles may be eligible for larger first-year deductions; certain sport utility vehicles (over 6,000 lbs and not more than 14,000 lbs GVWR) have a Section 179 cap of $32,000 for tax years beginning in 2026 (prorated by business use); and passenger cars and light trucks (6,000 lbs GVWR or less) are subject to annual “luxury auto” depreciation limits, also prorated by business use. For details, see our Section 179 Vehicle Deductions page.

Financing generally works fine—Section 179 is based on when the vehicle is placed in service and whether you’re treated as the owner for tax purposes. A true lease generally doesn’t qualify for Section 179 (you typically deduct lease payments instead), but some lease-to-own arrangements may be treated as a purchase. In all cases, the vehicle must be used more than 50% for business and placed in service during the tax year.

Section 179 treats vehicles differently based on weight, design, and business use. Some vocational or non-personal-use vehicles may be eligible for larger first-year deductions. Certain sport utility vehicles (over 6,000 lbs and not more than 14,000 lbs GVWR) have a Section 179 cap of $32,000 for tax years beginning in 2026 (prorated by business use), with remaining basis potentially eligible for bonus or regular depreciation. Passenger cars and light trucks (6,000 lbs GVWR or less) are subject to annual “luxury auto” depreciation limits, also prorated by business use. For details, see our Section 179 Vehicle Deductions page.

Section 179 is an election to expense qualifying property up to annual limits and is generally limited to taxable income from the active conduct of a trade or business (with carryforward of disallowed amounts). Bonus depreciation (additional first-year depreciation), when available, is generally not limited by taxable income and can create or increase a net operating loss, subject to NOL rules. Many businesses use Section 179 first, then apply bonus depreciation to remaining eligible basis.

Yes, you can combine Section 179 with bonus depreciation to maximize your tax benefits. After taking the Section 179 deduction, you can apply bonus depreciation (generally 100% for eligible property acquired and placed in service after Jan. 19, 2025) to any remaining eligible basis. This strategy works particularly well for larger equipment purchases that exceed the Section 179 limit. For a detailed comparison of these two tax benefits, see our guide on Section 179 vs. Bonus Depreciation.

Elect the deduction by completing Part I of IRS Form 4562 and attaching it to your timely filed tax return (including extensions) for the year the property is placed in service. Keep purchase/financing paperwork and business-use records with your files. For step-by-step guidance, see our How to Elect Section 179 page.

Not always. While many states follow federal Section 179 rules, others impose stricter limits or exclude certain assets. These differences can affect your overall tax liability. Always review your state’s guidelines or consult a local tax expert to ensure full compliance with state-specific rules. For more details, see State Section 179 Conformity.

If an asset’s business use drops to 50% or less—or it’s disposed of early—the excess Section 179 deduction over MACRS depreciation must be recaptured as ordinary income. For passthrough entities, this is computed at the entity level and passed through to owners via Schedule K-1 and Form 4797.

Yes. Congress has updated Section 179 (and bonus depreciation) multiple times—changing dollar limits, eligible property rules, and first-year depreciation rates. While Section 179 is a permanent part of the tax code, specific limits and related depreciation rules can change. For a timeline of major updates, see our Section 179 Legislative History page.

To substantiate a Section 179 vehicle deduction, keep purchase or financing documents, registration/title records, and a contemporaneous mileage log (dates, miles, and business purpose) showing more than 50% business use. Good recordkeeping matters because vehicles are “listed property” with stricter substantiation rules, and deductions may be reduced or recaptured if business use drops to 50% or less.

Qualifying equipment includes tangible business property such as machinery, computers, office furniture, and off-the-shelf software used more than 50% for business. Vehicles can also qualify, but rules vary: many non-passenger “work” vehicles may be eligible for larger deductions, while passenger vehicles are subject to special caps and limitations.

Yes. Used equipment qualifies if it is “new to your business” and meets all IRS criteria, including a business-use threshold of over 50%. It must be purchased from a non-related party and placed into service during the tax year, all within the annual deduction limits.

Off-the-shelf software generally qualifies if it is readily available for purchase by the general public, subject to a nonexclusive license, and not substantially modified. However, many subscription-based or cloud-hosted services may not meet the requirements for Section 179 property. For details, see our Section 179 and Software page, or consult a tax professional for your specific situation.

If equipment is sold or disposed of before the end of its useful life, you may have to recapture some of the previously deducted amount as taxable income. The recapture rules adjust your benefit if the asset’s business use decreases. Consult IRS guidelines or a tax professional for proper handling.

If you purchase or finance equipment, you can generally claim Section 179 in the year the asset is placed in service. A true lease generally doesn’t qualify for Section 179 because you don’t own the property for tax purposes—instead, you typically deduct lease payments as you pay them. Some lease-to-own arrangements may be treated as a purchase; check with your tax professional. See our Section 179 Qualified Financing page for more.

Section 179 is limited to taxable income from the active conduct of a trade or business, so you may not be able to use the full deduction in a loss year. Any disallowed Section 179 amount is generally carried forward to future tax years. Bonus depreciation, by contrast, is not limited by taxable income and can create or increase a net operating loss, which may carry forward under the NOL rules. Consult a tax professional to determine the best strategy for your situation.

Yes. The key requirement is that the property is placed in service (ready and available for use) during the tax year you’re claiming the deduction—by December 31 for most calendar-year taxpayers. Ordering or paying for equipment isn’t enough if it isn’t placed in service in time. Missing the deadline generally defers the deduction to the following year.
