Does the §280F luxury-auto cap also get cut in half if I sell the car mid-year?

No, and this is the exact mistake this rule exists to prevent. Publication 463 states directly: 'The depreciation limits aren't reduced if you use a car for less than a full year. This means that you don't reduce the limit when you either place a car in service or dispose of a car during the year.' You halve (or prorate) the computed MACRS depreciation for the disposition year, then compare that already-halved number against the full, un-prorated annual §280F dollar limit for that tax year — the one keyed to the calendar year the car was originally placed in service. Halving the cap on top of halving the depreciation double-counts the proration and can understate a deduction that was never actually capped.

How do I know whether to divide by 2 or use a mid-quarter percentage?

Whichever convention you used for the vehicle every prior year is the one you use for the disposition-year adjustment — you don't get to pick a different one just because you're selling. Almost every freelancer with a single vehicle purchase uses the half-year convention (divide by 2). The mid-quarter convention only applies if more than 40% of the total basis of all depreciable property you placed in service that year fell in the fourth quarter, which is a first-year determination made when the vehicle entered service, not something that changes at disposition. If you're not sure which convention applies to your vehicle, check the Form 4562 you filed the year you bought it — the depreciation method and convention are recorded there.

Does this affect the gain or loss I report when I sell the vehicle?

Yes, directly — the disposition-year depreciation amount is part of what sets your adjusted basis on the sale date, and adjusted basis is what your gain or loss is measured against on Form 4797. Getting the disposition-year figure wrong (for example, by wrongly halving the cap and understating the year's allowed depreciation) understates your total accumulated depreciation, which overstates your adjusted basis and understates your taxable gain — or overstates a deductible loss. The corpus already covers the separate mechanics of a trade-in, a casualty, and a straight sale; this rule is the missing step that has to happen before any of those gain-or-loss computations can be trusted for a mid-year disposition.

What if I used the standard mileage rate instead of actual expenses?

This entire rule doesn't apply to you. The standard mileage rate has its own built-in depreciation component — a flat cents-per-mile figure the IRS publishes annually — that reduces your basis mile by mile rather than through an annual MACRS table amount, and it isn't affected by when during the year you dispose of the car. The 'year of disposition' reduced-depreciation rule in Publication 463 is specifically about the actual expense method's MACRS-based depreciation. If you sell a standard-mileage vehicle mid-year, you simply stop accruing the depreciation component on the date of sale; there's no halving or mid-quarter percentage to apply.

Does the §280F cap still need to be reduced for anything else in the disposition year?

Yes — for business-use percentage, which is a separate and independent reduction from the one this rule addresses. Publication 463 requires multiplying the dollar cap by your percentage of business use for the year before comparing it to your computed depreciation, regardless of whether that year happens to be the year of disposition. A vehicle used 80% for business in its disposition year applies that 80% to the full annual cap first, and only then compares the result to the halved (or mid-quarter-adjusted) MACRS amount. The 'don't halve the cap for a partial year' rule and the 'do reduce the cap for personal use' rule operate on the same dollar figure but for entirely different reasons, and conflating them produces the same kind of error in the opposite direction.

Where does the disposition-year depreciation figure actually get used on my return?

It's the last entry in your running depreciation total for the vehicle, computed on Form 4562 for that final year alongside every other depreciable asset. That running total is what you subtract from original cost to get adjusted basis, which then feeds directly into the gain-or-loss computation on Form 4797 — the same form and the same routing the corpus already establishes for a business vehicle trade-in, casualty, or straight sale. The disposition-year depreciation deduction isn't reported separately from that gain-or-loss computation; it's an input to it.

Selling a Depreciated Business Vehicle Mid-Year: Why the §280F Cap Doesn't Get Cut in Half

Q: What happens to my vehicle's depreciation deduction in the year I sell it?

If you use the actual expense method (not the standard mileage rate) and dispose of the car before the end of its 5-year MACRS recovery period, IRS Publication 463 requires a reduced depreciation deduction for that final year rather than a full year's amount. If the half-year convention applied all along, take the ordinary full-year MACRS percentage-table amount for that year and divide it by 2. If the mid-quarter convention applied, multiply the full-year amount instead by 12.5%, 37.5%, 62.5%, or 87.5%, depending on which quarter of the year you disposed of the car. That reduced figure — not the full-year table amount — is what you're allowed to deduct for the year of the sale, before checking it against the §280F dollar cap.

Published: September 30, 2026 · Reading time: 11 min

TL;DR: Sell, trade, or total a business vehicle you've depreciated under the actual expense method mid-way through its recovery period, and Publication 463 requires a reduced depreciation deduction for that final year — half the normal MACRS amount under the half-year convention, or a mid-quarter percentage (12.5% / 37.5% / 62.5% / 87.5%) if that convention applied. What doesn't get reduced is the §280F luxury-auto dollar cap you check that figure against: Publication 463 says plainly that the cap "aren't reduced if you use a car for less than a full year" — for placing it in service or disposing of it. Halve the depreciation, not the cap, or you understate a real deduction. In the worked example below, a freelance videographer's $65,000 SUV — sold in July 2026, in its third year of MACRS depreciation — nets a correct $6,240 disposition-year deduction; wrongly halving the year's $11,900 cap on top of the depreciation would have understated that by $290.

The corpus already has thorough coverage of what happens to gain or loss when a business vehicle changes hands — a trade-in, a totaled car, a gifted vehicle sold years later. All of that math starts from one number: your adjusted basis on the date of disposition. And for a vehicle depreciated with actual expenses and MACRS, adjusted basis in the year of a mid-year sale depends on a rule none of those posts walk through — how much depreciation you're even allowed to claim for the stub year in which you sold the thing.

The Rule: A Reduced Deduction for the Year You Dispose of the Car

Publication 463's "Disposition of a Car" section states the general framework directly:

"If you dispose of your car, you may have a taxable gain or a deductible loss. The portion of any gain that is due to depreciation (including any section 179 deduction, clean-fuel vehicle deduction (for vehicles placed in service before January 1, 2006), and special depreciation allowance) that you claimed on the car will be treated as ordinary income."

Buried inside that section, under its own subheading, is the piece that this guide is actually about:

"Depreciation deduction for the year of disposition. If you deduct actual car expenses and you dispose of your car before the end of the recovery period (years 2 through 5), you are allowed a reduced depreciation deduction in the year of disposition."

"Reduced" isn't vague — Publication 463 gives the exact mechanics:

"If you dispose of the vehicle in years 2 through 5 and the half-year convention applies, then the full year's depreciation amount must be divided by 2. If the mid-quarter convention applies, multiply the full year's depreciation by the percentage from the following table for the quarter that you disposed of the car."

Quarter disposed	Percentage
First	12.5%
Second	37.5%
Third	62.5%
Fourth	87.5%

Almost every freelancer with one vehicle purchased in a normal year uses the half-year convention, so in practice this usually means: take the ordinary full-year MACRS table percentage for that year, multiply by your original basis as always, and then divide the result by 2. That halved figure is your tentative disposition-year deduction — tentative, because one more check remains.

The Trap: The Very Next Sentence Caps It Against a Number That Was Never Halved

Immediately after the disposition-year reduction, Publication 463 adds:

"If the car is subject to the Depreciation Limits, discussed earlier, reduce (but don't increase) the computed depreciation to this amount."

"This amount" is the §280F annual dollar cap — and the caps section, discussed earlier in the same publication, is unambiguous about what happens to that cap for a partial year:

"Car used less than full year. The depreciation limits aren't reduced if you use a car for less than a full year. This means that you don't reduce the limit when you either place a car in service or dispose of a car during the year."

Read the two rules side by side and the trap is obvious once it's pointed out, and easy to fall into if it isn't: the computed depreciation for the disposition year gets cut in half. The dollar cap you compare it to does not. A freelancer who reasons "I only owned the car for half this year, so both my deduction and my cap should be halved" is applying a plausible-sounding symmetry that Publication 463 explicitly rejects for one side of the comparison. The two "less than a full year" rules aren't parallel — one prorates a computed amount, the other protects a fixed statutory ceiling from being prorated at all.

The one thing that does reduce the cap, prorated year or not, is your business-use percentage — a completely separate adjustment covered in full in the corpus's business-use-percentage guide. Publication 463: "The depreciation limits are reduced based on your percentage of personal use. If you use a car less than 100% in your business or work, you must determine the depreciation deduction limit by multiplying the limit amount by the percentage of business and investment use during the tax year." That reduction stacks with everything below; it just isn't the same rule as the one this guide is about, and the two are easy to conflate because they touch the same number.

Worked Example: A Videography SUV, Bought 2024, Sold Mid-2026

Renata Solis runs a freelance wedding and event videography business. In March 2024 she bought a fully-equipped 4x4 SUV — rated at 5,650 lbs GVWR, under the 6,000-lb threshold, so it's squarely a "passenger automobile" under §280F — for $65,000, to reach rural and off-grid venues with her camera and lighting gear. She uses it 100% for business (she drives a separate personal car for everything else) and depreciates it under the actual expense method with ordinary MACRS, the half-year convention, no bonus depreciation and no §179 election. She sells it on July 15, 2026, in the middle of its third tax year of ownership.

Step 1: Years 1 and 2 — full years, capped against Rev. Proc. 2024-13 Table 2

Because Renata didn't claim bonus depreciation, Table 2 of Rev. Proc. 2024-13 — the table for a passenger automobile placed in service in 2024 with no §168(k) additional first-year deduction — sets her caps: $12,400 (1st year), $19,800 (2nd year), $11,900 (3rd year), $7,160 (each year after), confirmed directly from the revenue procedure's text.

node -e "
const basis = 65000;
const pct = { y1: 0.20, y2: 0.32, y3: 0.192 }; // Pub. 946 Table A-1, 5-year property, half-year convention
const cap = { y1: 12400, y2: 19800, y3: 11900 }; // Rev. Proc. 2024-13, Table 2 (no bonus)

const y1Full = basis * pct.y1;
const y1Allowed = Math.min(y1Full, cap.y1);
console.log('Y1 (2024) full MACRS', y1Full.toFixed(2), 'cap', cap.y1, 'allowed', y1Allowed.toFixed(2));

const y2Full = basis * pct.y2;
const y2Allowed = Math.min(y2Full, cap.y2);
console.log('Y2 (2025) full MACRS', y2Full.toFixed(2), 'cap', cap.y2, 'allowed', y2Allowed.toFixed(2));
"

Y1 (2024) full MACRS 13000.00 cap 12400 allowed 12400.00
Y2 (2025) full MACRS 20800.00 cap 19800 allowed 19800.00

Both years hit the cap — the SUV's price, not any special elections, is what triggers it. $600 in 2024 and $1,000 in 2025 go unclaimed for now; ordinarily that excess would become recoverable "unrecovered basis" under §280F(a)(1)(B) once the recovery period ends, but Renata is about to sell the car before that ever happens. It isn't lost — it simply stays in the car's basis, which matters in Step 3.

Step 2: 2026 — the disposition year, computed correctly

node -e "
const basis = 65000;
const y3Pct = 0.192;          // Pub. 946 Table A-1, year 3 of 5-year property
const y3Cap = 11900;          // Rev. Proc. 2024-13 Table 2, 3rd year — NOT halved

const y3FullYear = basis * y3Pct;
const y3Halved = y3FullYear / 2;                 // half-year convention, disposition-year rule
const y3Allowed = Math.min(y3Halved, y3Cap);     // compare against the FULL cap, unprorated

console.log('Y3 (2026) full-year MACRS', y3FullYear.toFixed(2));
console.log('Y3 halved (disposition-year figure)', y3Halved.toFixed(2));
console.log('Y3 allowed (capped at the un-halved limit)', y3Allowed.toFixed(2));

// The wrong way: halving the cap too
const wrongCap = y3Cap / 2;
const wrongAllowed = Math.min(y3Halved, wrongCap);
console.log('WRONG: halved cap', wrongCap.toFixed(2), '-> wrongly allowed', wrongAllowed.toFixed(2));
console.log('Understatement from halving the cap', (y3Allowed - wrongAllowed).toFixed(2));
"

Y3 (2026) full-year MACRS 12480.00
Y3 halved (disposition-year figure) 6240.00
Y3 allowed (capped at the un-halved limit) 6240.00
WRONG: halved cap 5950.00
Understatement from halving the cap 290.00

Renata's correctly computed 2026 depreciation deduction is $6,240 — under the real $11,900 cap, so it isn't capped at all. A preparer who also halved the cap to $5,950 would have understated her final-year deduction by $290, on the theory that "half a year of ownership means half the limit too." In Renata's case the cap never actually binds either way, which is itself worth knowing: with a $65,000 vehicle, the halved MACRS figure would have to come from a considerably pricier car before the real (un-halved) cap would bind post-halving.

node -e "
const y3Pct = 0.192;
const y3Cap = 11900;
const breakevenBasis = (y3Cap * 2) / y3Pct;
console.log('Vehicle cost at which the Y3 cap would bind even after halving:', breakevenBasis.toFixed(2));
"

Vehicle cost at which the Y3 cap would bind even after halving: 123958.33

At current caps, only a passenger automobile costing more than roughly $123,958 would have its third-year cap bind after the disposition-year halving — well above what most freelancers spend, but the mechanism is identical for a $30,000 hatchback or a $200,000 vehicle. The rule doesn't care about the price; it cares about which number you're allowed to prorate.

Step 3: From depreciation to adjusted basis to gain

node -e "
const originalCost = 65000;
const y1 = 12400.00, y2 = 19800.00, y3 = 6240.00;
const totalDepreciation = y1 + y2 + y3;
const adjustedBasis = originalCost - totalDepreciation;
console.log('Total depreciation allowed, 2024-2026', totalDepreciation.toFixed(2));
console.log('Adjusted basis at sale', adjustedBasis.toFixed(2));

const salePrice = 30000;
const gain = salePrice - adjustedBasis;
console.log('Sale price', salePrice, 'Gain', gain.toFixed(2));
console.log('Section 1245 ordinary-income portion (gain is less than total depreciation claimed, so all of it recaptures)', Math.min(gain, totalDepreciation).toFixed(2));
"

Total depreciation allowed, 2024-2026 38440.00
Adjusted basis at sale 26560.00
Sale price 30000 Gain 3440.00
Section 1245 ordinary-income portion (gain is less than total depreciation claimed, so all of it recaptures) 3440.00

Renata sells the SUV for $30,000 against a $26,560 adjusted basis, for a $3,440 gain — entirely ordinary income under §1245(a), because the gain is smaller than the $38,440 of depreciation she actually claimed. That gain, and the depreciation figures behind it, get reported on Form 4797, following the same routing the corpus already establishes for a business vehicle sale generally — this guide's contribution is only the $6,240 figure that had to be right before any of that could be computed.

Cross-checking the figures

Tax year	Full-year MACRS	Disposition adjustment	§280F cap (unprorated)	Allowed depreciation
2024 (1st year)	$13,000.00	none (full year)	$12,400	$12,400.00
2025 (2nd year)	$20,800.00	none (full year)	$19,800	$19,800.00
2026 (3rd year, sold July 15)	$12,480.00	÷ 2 (half-year, disposition year)	$11,900 (not halved)	$6,240.00
Total depreciation claimed				$38,440.00

$65,000 (original cost) − $38,440.00 (total depreciation) = $26,560.00 adjusted basis, matching Step 3 exactly.

Mixed Business and Personal Use

Everything above assumes 100% business use throughout, matching how Publication 463 itself frames the disposition-year rule. If Renata's SUV were, say, 80% business, two adjustments layer on top of everything above — neither one changes the disposition-year halving itself: first, every year's cap gets multiplied by that year's business-use percentage before it's compared to anything, per the "Reduction for personal use" rule quoted above; second, only the business-use percentage of the resulting gain is reported as business gain on Form 4797 (the personal-use share goes to Schedule D instead, and a loss on that personal-use share isn't deductible at all), following the same mixed-use rule the corpus already establishes for a trade-in or a totaled vehicle. The disposition-year computation in this guide — halve the depreciation, don't halve the cap — is unchanged; it just runs against a smaller, business-use-adjusted cap.

Common Mistakes to Avoid

Halving the §280F cap along with the depreciation. The cap is fixed for the entire tax year regardless of when you place a car in service or dispose of it; only the computed MACRS amount for the disposition year gets prorated.
Using the wrong year's cap table. The dollar limit is keyed to the calendar year the car was originally placed in service, not the year you sold it — a car bought in 2024 and sold in 2026 uses Rev. Proc. 2024-13's tables in every year it's owned, including 2026.
Applying the half-year convention when the mid-quarter convention actually governed. Whichever convention applied when the vehicle was placed in service governs every later year, including the disposition year — check the original Form 4562, don't assume.
Forgetting the disposition-year adjustment entirely and claiming a full year's MACRS percentage-table amount for a car sold mid-year, which overstates depreciation and understates adjusted basis (and therefore overstates any resulting loss or understates any gain).
Applying this rule to a standard-mileage vehicle. The rate's built-in depreciation component isn't governed by this Publication 463 section at all — it simply stops accruing on the sale date.
Skipping straight to the gain-or-loss computation without first locking down the disposition-year depreciation figure, which is a required input to adjusted basis, not an optional refinement.

Frequently Asked Questions

What happens to my vehicle's depreciation deduction in the year I sell it?

If you use actual expenses and MACRS and dispose of the car before the recovery period ends, Publication 463 requires a reduced deduction for that year: divide the full-year MACRS percentage-table amount by 2 (half-year convention) or apply a mid-quarter percentage, before comparing to the §280F cap.

Does the §280F cap also get cut in half if I sell mid-year?

No. Publication 463 states the depreciation limits "aren't reduced if you use a car for less than a full year," for placing it in service or disposing of it. Only the computed depreciation is prorated; the cap you check it against stays at its full annual figure.

How do I know which convention to use for the disposition-year adjustment?

Whatever convention applied to the vehicle from the year it was placed in service — check the Form 4562 filed that year. Almost every single-vehicle freelancer used the half-year convention.

Does this affect the gain or loss I report on the sale?

Yes. The disposition-year depreciation feeds directly into adjusted basis, which is what your Form 4797 gain or loss is measured against.

What if I used the standard mileage rate instead?

This rule doesn't apply. The mileage rate's built-in depreciation component isn't a MACRS table amount, and it simply stops accruing on the date of sale.

Does the cap still get reduced for personal use in the disposition year?

Yes — that's a separate, independent adjustment. Multiply the full annual cap by your business-use percentage for the year, then compare that (still un-prorated-for-time) figure to your halved or mid-quarter-adjusted depreciation.

Where does this figure show up on my return?

It's the final year's entry in your Form 4562 depreciation schedule for the vehicle, which sets adjusted basis and flows into the Form 4797 gain-or-loss computation for the sale.
