Section 179 Deduction FAQs (2025)

Section 179 allows businesses to deduct the full purchase price of qualifying equipment or software in the tax year it’s placed in service. This immediate write-off reduces taxable income, preserves cash flow, and avoids the need to depreciate assets over multiple years.

For 2025, the maximum deduction is $2,500,000, with a phase-out starting at $4,000,000 in equipment purchases. Every dollar spent over this threshold reduces your available deduction. Always verify the current IRS guidelines, as these limits adjust annually for inflation.

Note: The Section 179 deduction phases out dollar‑for‑dollar when total qualifying purchases exceed $4,000,000 and is fully phased out at $6,500,000.

H.R.1 (effective for tax years beginning after December 31, 2024) doubled the Section 179 limit to $2,500,000, raised the phase‑out threshold to $4,000,000, and reinstated 100% bonus depreciation.

Yes. Section 179 is a permanent tax code provision that allows annual deductions for qualifying purchases made by year-end. However, limits based on annual spending and taxable income apply, so it’s important to consult a tax professional to optimize your yearly strategy.

Many business vehicles, including SUVs, pickup trucks, and vans, qualify if used over 50% for business. However, different rules apply: vocational or specialized vehicles can receive full deductions; heavier passenger vehicles (6,000–14,000 lbs GVWR) have a capped deduction of $31,300; and cars/light trucks (under 6,000 lbs) face a first-year cap of about $20,400, prorated by business use.

Yes. Financing or leasing a vehicle qualifies for Section 179 as long as it meets IRS business-use and weight requirements. Ensure the vehicle is titled in the business name and placed into service by year-end to qualify for the applicable deduction and bonus depreciation, if available.

Section 179 treats vehicles differently based on weight and usage. Vocational or specialized vehicles, regardless of weight, can qualify for the full deduction. Heavier passenger vehicles (6,000–14,000 lbs GVWR) have a capped deduction of $31,300, while cars and light trucks (under 6,000 lbs) face a first-year cap of about $20,400, adjusted for business use.

Section 179 provides an immediate deduction up to set limits, while Bonus Depreciation applies to the remaining cost after Section 179 is taken. Bonus Depreciation can exceed taxable income in the current year and may carry forward any excess, making it a valuable complement for larger capital investments.

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 (100% for 2025) to any remaining purchase price. 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, listing each asset’s cost and business-use percentage. Attach this form to your tax return for the year the equipment is placed in service. For complex situations, consult a tax advisor to ensure proper compliance.

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. Acts like the PATH Act have historically increased Section 179 limits and expanded eligibility to stimulate business investment. Although the deduction is now a permanent fixture, future legislative changes may modify limits or rules. Stay updated on IRS announcements to ensure your strategy remains optimal.

To substantiate your Section 179 claim on vehicles, maintain detailed records including purchase or financing documents, proof that the vehicle is titled in your business name, and logs verifying over 50% business use. These records are crucial in case of an IRS audit and to support your deduction.

Qualifying equipment includes tangible business property such as machinery, computers, office furniture, and off-the-shelf software used more than 50% for business. Vehicles also qualify—but note that rules vary: vocational or specialized vehicles may be fully expensed, while passenger vehicles have weight-based caps.

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 isn’t custom-developed and is predominantly used for business. However, many subscription-based or cloud services may not meet the “acquired property” criteria. Always review IRS guidelines or consult a 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.
