Section 1031 Like-Kind Exchange for Trade Vehicles

Why this matters

Section 1031 of the Internal Revenue Code allows like-kind exchange (LKE) of business property without immediate tax recognition. The Tax Cuts and Jobs Act 2017 restricted 1031 to real property only; vehicles and equipment can no longer use 1031 directly. However, related strategies (Section 179 expensing, bonus depreciation, vehicle deduction) accomplish similar tax benefits. Understanding these alternatives is essential for contractors making vehicle purchasing decisions.

What Section 1031 was (and isn't)

Pre-2018:

• 1031 allowed exchange of business property
• Including vehicles and equipment
• Defer tax on gain

Post-2017 (current):

• 1031 restricted to real property (real estate) only
• Vehicles and equipment no longer use 1031
• Different strategies apply

Current vehicle deduction strategies

Section 179 expensing

• Allows expensing of business equipment (including vehicles)
• 100 percent deduction year of purchase
• Specific caps and rules

Bonus depreciation

• Accelerated depreciation
• Currently 60 percent (declining; 100 percent through 2022; 80 in 2023; 60 in 2024; 40 in 2025; 20 in 2026; 0 in 2027)
• Combined with Section 179

Standard mileage deduction

• Per-mile deduction
• 2024 rate: 67 cents per mile (IRS Notice 2024-08). The IRS resets this every January in a December notice, so pull the current year's figure before filing.
• Simpler accounting

Actual expense method

• Actual vehicle expenses (gas, insurance, repairs, depreciation)
• More tracking

Section 179 in detail

Limit

• $1,160,000 maximum for tax year 2023 under IRC Section 179(b)(1)
• Phase-out begins at $2,890,000 of equipment placed in service (2023, IRC Section 179(b)(2))
• Both figures re-index every year in the IRS annual inflation-adjustment revenue procedure. Pull the current year's numbers before you plan a purchase around them; the ones above are illustrative of the structure, not of this year's ceiling.

Eligible

• New or used equipment
• Used primarily in business (over 50 percent business use)
• Tangible personal property

Vehicle limits

The two caps below are different animals, and mixing them up is the single most expensive mistake in this article. One is a ceiling on the entire first year. The other is a ceiling on one deduction with room left above it.

For passenger vehicles (rated at or under 6,000 lb GVWR, the Section 280F "passenger automobile" class):

• $20,200 first-year cap for tax year 2024, the IRC Section 280F luxury-auto limit, re-indexed annually by IRS revenue procedure
• This is a ceiling on total first-year depreciation, not a Section 179 line item. Section 179 expensing, bonus depreciation, and the first-year MACRS slice all sit underneath it and together cannot exceed it. Nothing stacks on top of it. Basis above the cap comes back in later years, subject to the same annual 280F ceilings.

For SUVs (over 6,000 lb GVWR):

• $30,500 maximum for tax year 2024, the IRC Section 179(b)(5) heavy-SUV cap, re-indexed annually by IRS revenue procedure
• Plus bonus depreciation on the basis remaining above that cap. Bonus genuinely does stack here, because a vehicle rated over 6,000 lb GVWR falls outside the Section 280F passenger-automobile definition and the luxury-auto ceiling never applies to it. That exclusion, not the 179 cap itself, is why the heavy vehicle wins.

For trucks (over 6,000 lb GVWR):

• Same as SUV
• Plus bonus depreciation on the remaining basis

Larger trucks (over specific weight):

• Full Section 179 deduction
• More aggressive

Heavy SUV / pickup advantage

For business vehicles meeting weight requirements:

• 100 percent expensed up to specific limit
• Combined with bonus depreciation
• Significant first-year deduction

Bonus depreciation

Schedule

The schedule shows decline through 2027.

Calculation

Bonus depreciation is applied on top of Section 179:

• Section 179 first (per limits)
• Then bonus depreciation on remaining basis
• Then standard depreciation if any remains

Examples

Example 1: Pickup truck for contractor

• Purchase: a substantial pickup (over 6,000 lb gross weight)
• 100 percent business use
• Section 179: up to $30,500 (heavy SUV / truck limit, tax year 2024; re-indexed annually)
• Bonus depreciation applies to the remainder above the Section 179 cap at the current-year bonus percentage (60 percent for 2024)
• Standard MACRS depreciation covers any residual basis over the 5-year recovery period
• First-year deduction combines the Section 179 cap, the bonus on the remainder, and the first-year MACRS slice on whatever is left
• Significant tax benefit

Example 2: Service van under 6,000 lb

• Purchase: a substantial van
• 100 percent business use
• Rated at or under 6,000 lb GVWR, so this is a Section 280F passenger automobile and the total first-year depreciation is capped at $20,200 (tax year 2024; re-indexed annually)
• Section 179, bonus depreciation, and first-year MACRS all count against that one ceiling. Electing 179 up to the cap leaves nothing for bonus to add in year one; bonus does not stack on top of a 280F-capped vehicle
• Basis above the cap is recovered in later years, each year subject to that year's 280F ceiling, which is why a van that just misses 6,000 lb takes far longer to write off than one that just clears it
• Check the door-jamb GVWR sticker before you plan the deduction. The difference between the two examples is a rating plate, not a price

Example 3: Large fleet expansion

• Purchase: 3 vehicles totaling a substantial cost
• Each vehicle treated separately
• Combined deductions reduce taxable income

Customer asks "Can I trade in?"

Yes, but the tax treatment differs:

Trade-in (old approach pre-2018)

• Trade-in value applied to new vehicle
• Old vehicle's basis carried into new
• Like-kind exchange (no gain recognized)

Sale and purchase (current approach)

• Old vehicle sold (taxable gain on the sale)
• New vehicle purchased separately
• Section 179 / bonus depreciation on new

Net effect

• May be similar tax effect
• Documentation differs
• Accountant should advise

Specific situations

Contractor with personal use of vehicle

• Business use percentage matters
• Track miles per category
• Apply deduction only to business percentage

Multiple vehicles purchased

• Each treated separately
• All can benefit from Section 179 / bonus

Replacement of older vehicle

• Sell old vehicle
• Purchase new
• Tax effect on sale; tax benefit on purchase

Lease vs purchase

• Lease: monthly expense deductible
• Purchase: depreciation per above
• Specific math; accountant advises

Documentation required

For each vehicle:

Purchase documentation

• Bill of sale
• Vehicle identification
• Date of purchase
• Cost basis

Use documentation

• Business use percentage
• Mileage log
• Specific business trips

Depreciation records

• Section 179 election
• Bonus depreciation calculation
• Annual depreciation schedule

Common contractor mistakes

Confusing 1031 with Section 179

• 1031 is for real estate
• Vehicles use Section 179 / bonus depreciation

Wrong vehicle classification

• Heavy SUV vs passenger car
• Different limits
• Verify gross vehicle weight

Inadequate mileage tracking

• Personal use mixed with business
• IRS requires documentation
• Apps available

Missing Section 179 election

• Default depreciation may not maximize
• Election required on tax return

Treating all vehicles same

• Different categories
• Different limits
• Different rules

Accountant coordination

For each significant vehicle purchase:

Pre-purchase

• Discuss with accountant
• Tax strategy
• Cash flow impact
• Specific year benefits

Year-end planning

• Review purchases
• Maximize deductions
• Document for tax return

Tax return

• Form 4562 (Depreciation and Amortization)
• Specific line items for vehicles

State tax considerations

Some states:

• Allow Section 179 differently than federal
• Have specific vehicle rules
• Sales tax considerations

Verify state rules.

Specific vehicle categories

Light trucks (6,000 lb GVWR or under)

• Treated as a Section 280F passenger automobile
• One combined first-year ceiling covering 179, bonus, and MACRS together
• Bonus adds nothing once the ceiling is reached

Heavy trucks (6,000 to 14,000 lb)

• Heavy SUV / truck limit
• Higher Section 179
• Plus bonus

Specialty (over 14,000 lb)

• Full Section 179
• No specific cap
• Plus bonus

Trailers

Trailers are the easy category, and contractors routinely leave the deduction on the table because they think of a trailer as an accessory rather than an asset.

• Not a "passenger automobile." A trailer has no engine and carries no driver, so the luxury-auto limits under Section 280F do not apply to it. That is the whole reason it is treated better than the pickup pulling it.
• Full Section 179 expensing, subject only to the overall annual limit and the business-income limitation. No per-vehicle cap of its own.
• Bonus depreciation applies at the current-year percentage on whatever is not expensed under 179, including used trailers as long as they are new to you and not acquired from a related party.
• Business-use percentage still governs. A dump trailer that hauls material five days a week and the family's side-by-side on weekends gets prorated. Keep a use log if the split is realistic to question.
• Enclosed job trailers, dump trailers, equipment trailers, and tool trailers all qualify as tangible business personal property. So do the permanent build-out items inside a trailer that convert it to a mobile shop.
• Register and title it to the business, and keep the bill of sale, the title, the registration, and the VIN with the depreciation schedule. Trailer paperwork is the most commonly lost documentation in a contractor's fixed-asset file.
• On sale, expect depreciation recapture as ordinary income under Section 1245, same as any other expensed equipment. A fully expensed trailer sold for a real number produces real taxable income, and 1031 is no longer available to defer it.

Have the accountant place the trailer in service in the year it is actually available for use, not the year it is ordered.
