Tax Strategy • §179

Section 179 Expensing

Immediately deduct the full cost of qualifying business equipment and software in the year of purchase — up to $1,250,000 in 2026 — instead of depreciating over 5–7 years.

$1,250,000Section 179 deduction limit (2026)

Section 179 of the Internal Revenue Code allows businesses to immediately expense (deduct in full) the cost of qualifying property placed in service during the tax year, rather than recovering the cost through multi-year depreciation schedules. The 2026 §179 deduction limit is $1,250,000, with a phase-out beginning at $3,130,000 of total qualifying property placed in service. Section 179 is the most commonly used first-year expensing election for small and mid-size businesses purchasing equipment, vehicles, and off-the-shelf software.

Qualifying Property

Section 179 applies to tangible personal property used in a trade or business. Qualifying property includes:

Property TypeExamples§179 Eligible?
Machinery and equipmentMedical equipment, manufacturing machinery, HVAC unitsYes
Business vehiclesSUVs over 6,000 lbs GVWR, trucks, vansYes (SUV cap: $31,300 in 2026)
Off-the-shelf softwareQuickBooks, Adobe, Microsoft 365Yes
Qualified improvement property (QIP)Interior improvements to nonresidential buildingsYes
Listed propertyComputers, cameras, smartphonesYes (if >50% business use)
Real property (buildings, land)Office building, warehouseNo (except QIP)
Property used outside the USAny property used predominantly outside the USNo

Section 179 vs. Bonus Depreciation

Section 179 and bonus depreciation (§168(k)) are both first-year expensing mechanisms, but they differ in important ways:

FeatureSection 179Bonus Depreciation (2026)
2026 deduction rate100% up to $1,250,000 limit40% (phasing down from 100%)
Income limitationCannot exceed taxable income from active businessNo income limitation — can create a loss
Phase-outDollar-for-dollar above $3,130,000 of purchasesNo phase-out
Used propertyEligible (if new to the taxpayer)Eligible (if new to the taxpayer)
CarryforwardUnused §179 carries forward indefinitelyNo carryforward — creates NOL
State conformityMany states conformMany states do NOT conform (California, New York)

Best practice: Use §179 first (up to the income limitation), then layer bonus depreciation on top to eliminate remaining taxable income. This preserves the §179 carryforward for future years when income is higher.

SUV Limitation

Section 179(b)(5) imposes a special cap on SUVs with a GVWR between 6,001 and 14,000 lbs: the §179 deduction for an SUV is limited to $31,300 in 2026 (indexed for inflation). This cap was enacted to prevent business owners from fully expensing luxury SUVs in the first year. Vehicles with a GVWR over 14,000 lbs (heavy trucks, cargo vans) are not subject to this cap and can be fully expensed under §179.

The §179 SUV cap does not limit bonus depreciation — a business can still claim 100% bonus depreciation (restored by OBBBA for property placed in service after Jan 19, 2025) on the remaining cost of an SUV after the §179 cap is applied.

Income Limitation and Carryforward

The §179 deduction cannot exceed the taxpayer's aggregate taxable income from active trades or businesses for the year. Unused §179 deductions carry forward to future tax years indefinitely. This differs from bonus depreciation, which creates a net operating loss (NOL) that carries forward at 80% of taxable income under §172.

For S-Corp shareholders and partnership partners, the §179 deduction passes through to the owner's individual return and is limited by the owner's share of the entity's taxable income — not the entity's gross income.

More Tax Planning FAQs

What is the S-Corp election and how does it reduce self-employment tax?
An S-Corp election allows the owner to split income between a reasonable salary (subject to 15.3% FICA) and distributions (not subject to FICA). For a business owner with $200,000 in net profit paying an $80,000 salary, the annual SE tax savings are approximately $15,500–$18,500. The S-Corp must file Form 2553 within 75 days of formation.
What is the Section 199A QBI deduction and how does it apply?
The §199A deduction allows pass-through business owners to deduct up to 23% of qualified business income (QBI) from taxable income under OBBBA. For taxpayers above $403,500 (MFJ) in 2026, the deduction is limited to the greater of 50% of W-2 wages or 25% of W-2 wages plus 2.5% of qualified property.
What retirement plan options are available for self-employed professionals?
Self-employed professionals can establish a Solo 401(k) (up to $70,000 in 2026), a SEP-IRA (25% of net self-employment income up to $70,000), a SIMPLE IRA ($16,500 + $3,500 catch-up), or a Defined Benefit Plan (up to $280,000+ depending on age). The Solo 401(k) is the best option for most self-employed professionals.
How does the home office deduction work for self-employed professionals?
Self-employed professionals who use a dedicated home office space exclusively and regularly for business qualify for the home office deduction under §280A. The deduction is calculated as a percentage of home expenses equal to the office square footage divided by total home square footage. The simplified method allows $5/sq ft up to 300 sq ft ($1,500 maximum).
What vehicle deductions are available for self-employed professionals?
Self-employed professionals can deduct vehicle expenses using either the standard mileage rate (70 cents/mile in 2026) or actual expenses. Vehicles with a GVWR over 6,000 lbs qualify for §179 expensing and bonus depreciation without luxury auto limits. A mileage log must be maintained for either method.
What is the Augusta Rule and how can it benefit business owners?
The Augusta Rule (§280A(g)) allows homeowners to rent their primary or secondary residence to their business for up to 14 days per year. The rental income is completely tax-free to the homeowner, and the business deducts the rent as a business expense. At $2,000–$3,000/day for 14 days, this strategy generates $28,000–$42,000 of tax-free income.
How does cost segregation apply to business owners who own real estate?
Cost segregation reclassifies building components into shorter depreciation categories eligible for bonus depreciation. For a $1M commercial property, cost segregation typically identifies $150,000–$250,000 of accelerated depreciation, generating $60,000–$100,000 in first-year deductions at the 100% bonus depreciation (restored by OBBBA for property placed in service after Jan 19, 2025) rate in 2026.
What is the self-employed health insurance deduction?
Self-employed professionals can deduct 100% of health insurance premiums (for themselves, their spouse, and dependents) as an above-the-line deduction under §162(l). This deduction reduces AGI and is available even if the taxpayer does not itemize. S-Corp owners must include premiums in W-2 wages before claiming the deduction.
How should a self-employed professional handle estimated tax payments?
Self-employed professionals must make quarterly estimated tax payments by April 15, June 15, September 15, and January 15. The safe harbor is 100% of prior year tax (110% if prior year AGI exceeded $150,000). Failure to pay sufficient estimated taxes results in an underpayment penalty under §6654.
How should a taxpayer set up documentation to support a Section 179 election for multiple asset purchases within a tax year?
To properly document a Section 179 election for multiple assets, the taxpayer must maintain detailed records showing the date each asset was placed in service, its cost, and its eligibility under §179. The election is made on IRS Form 4562, where each asset or class of assets is listed with the elected expense amount. It is critical to track the cumulative cost to ensure the $2,560,000 maximum deduction for 2026 is not exceeded, and to monitor the phase-out threshold of $4,090,000. Adequate documentation also includes invoices, purchase agreements, and proof of payment to substantiate the deduction upon audit.
What are the key steps a tax professional should take to file Section 179 expensing correctly for a client with multiple qualified property types?
First, identify all qualifying property placed in service during the tax year as defined under §179(d), including tangible personal property and qualified improvement property. Next, aggregate the total cost of these assets to assess the applicability of the $2,560,000 deduction limit and the $4,090,000 phase-out for 2026. Complete Form 4562, Part I, allocating the expense election among property categories carefully, ensuring compliance with SUV limits per §179(d)(4). Finally, verify that the client has sufficient taxable income to absorb the deduction, as per the income limitation rules, and consider the interaction with bonus depreciation under §168(k).
What specific documentation and records should be maintained to mitigate audit risk related to Section 179 expensing elections?
To reduce audit risk, maintain contemporaneous purchase documents, such as invoices and contracts, clearly indicating the date the asset was placed in service. Keep asset-specific records showing how the property qualifies under §179, including detailed descriptions and use logs if applicable. Retain completed IRS Form 4562 with the election clearly marked and signed, as well as computations demonstrating adherence to the $2,560,000 limit and phase-out threshold for 2026. Additionally, document the taxpayer’s taxable income calculations to support the income limitation rule, and maintain any engineering or appraisal reports if cost segregation studies are involved.
How does the Section 179 deduction phase-out work when a client exceeds the $4,090,000 threshold in 2026, and what are the implications?
The Section 179 deduction is reduced dollar-for-dollar by the amount the total cost of qualifying property placed in service exceeds $4,090,000 for 2026. For example, if a client places $4,590,000 of qualifying property in service, their maximum deduction is reduced by $500,000, resulting in a maximum allowable deduction of $2,060,000. Once the placed-in-service amount reaches $6,650,000, the Section 179 deduction is completely phased out. Tax professionals should advise clients to plan acquisitions carefully to optimize the expensing benefit and avoid unintended loss of valuable deductions.
If a client has both Section 179 eligible property and property eligible only for bonus depreciation under §168(k), how should these deductions be coordinated?
Section 179 expensing is applied first, allowing the taxpayer to elect to expense up to the statutory limits on qualifying property. Bonus depreciation under §168(k) is then applied to remaining basis amounts of eligible property that were not expensed under §179. Tax professionals should evaluate the client's taxable income, as Section 179 is limited by income, whereas bonus depreciation is not. Strategic planning involves determining the optimal allocation between the two to maximize current-year deductions while managing future depreciation and AMT considerations.
How can a tax professional explain the benefits and limitations of Section 179 expensing to a client unfamiliar with depreciation strategies?
Explain that Section 179 allows immediate expensing of up to $2,560,000 of qualifying business property costs in 2026, which can significantly reduce taxable income in the year assets are placed in service. Emphasize that this is unlike traditional depreciation, which spreads deductions over several years, and that the deduction phases out when purchases exceed $4,090,000. Also clarify that the deduction is limited to the amount of taxable income from active conduct of a trade or business, so it cannot create a loss. This immediate expensing provides cash flow benefits but requires careful planning to align with the client’s income and investment timing.
What are the special considerations and limits when applying Section 179 expensing to sport utility vehicles (SUVs) for 2026?
For SUVs placed in service in 2026 with a gross vehicle weight rating between 6,000 and 14,000 pounds, the maximum Section 179 deduction is limited to $29,000 per vehicle, as specified in §179(d)(4). This limit is substantially lower than the general $2,560,000 threshold and is designed to restrict expensing on passenger vehicles. Tax professionals must ensure that the deduction claimed on Form 4562 reflects this cap, and advise clients accordingly when acquiring SUVs for business use. Additionally, SUVs that exceed the weight threshold may qualify for higher expensing limits or bonus depreciation, so asset classification is critical.
