Wheelchair van tax deduction: Section 190 and the disabled access credit for conversions

Two federal tax provisions were written for the kind of work a wheelchair conversion involves: removing a barrier that keeps people with disabilities from using a vehicle. Section 190 is a deduction any business can take. Section 44, the disabled access credit, is a credit for small businesses, claimed on Form 8826. They work differently, and a NEMT company that converts vans may be able to use both. Your tax preparer makes the final call on how each applies.

The two breaks side by side

The deduction lowers taxable income. The credit lowers the tax itself, dollar for dollar, which makes it worth more per dollar of spending.

Section 190: a $15,000 yearly deduction

Section 190 lets a business elect to deduct, instead of capitalize, what it spends to make a facility or a “public transportation vehicle” it owns or leases more accessible to and usable by people with disabilities and people 65 or older. The cap has been $15,000 a year since a 1990 amendment. One regulation still mentions an older $25,000 figure, but the statute’s $15,000 is the limit that applies.

Four parts of the regulation (26 CFR 1.190-2 and 1.190-3) decide whether a van conversion fits:

• The vehicle. A public transportation vehicle is one that provides general or special transportation service to the public, including rides a business outside the transportation trade gives its own customers. A van that carries members of the public on paid rides fits that wording.
• The standard. The work has to bring the vehicle up to every part of one of the regulation’s standards. The bus standard lists a lift or ramp, room for a wheelchair user to reach a secure spot, and a securement device, along with step heights, handrails, signs, and lighting that suit a transit bus more than a van. A catch-all standard covers any other removal of a substantial barrier for a major group of people, such as wheelchair users, as long as the work creates no new barrier.
• The kind of cost. Only costs specifically for removing an existing barrier count. Costs of building or comprehensively renovating a vehicle, and normal replacement of depreciable property, do not.
• The election. You elect by claiming the deduction as its own identified line on a return filed by its due date, including extensions. The election covers all of that year’s qualifying costs and cannot be undone once the deadline passes.

The disabled access credit: up to $5,000 for a small business

Section 44 gives an eligible small business a credit equal to 50 percent of its eligible access spending above $250 and up to $10,250. Form 8826 does the math: subtract $250, cap the result at $10,000, and take half, so the credit tops out at $5,000.

• Who qualifies. In the preceding year, either gross receipts of $1 million or less, or a full-time headcount of 30 or fewer. A full-time employee works at least 30 hours a week for 20 or more weeks. Because the test uses “or,” a company with $2 million in receipts and 25 full-time employees, for example, still qualifies.
• What counts. Spending a small business needs to meet ADA requirements, including removing transportation barriers and buying or modifying equipment or devices for people with disabilities. It has to be reasonable and necessary, and it has to meet the standards in the regulations.
• A construction limit. Barrier removal tied to a facility first placed in service after November 5, 1990 does not count. That limit is written only for the barrier removal category, not the equipment category, which is one reason preparers look closely at how a conversion is billed.
• Groups and pass-throughs. Companies under common control count as one business. For a partnership or S corporation, the dollar limit applies to the entity and again to each owner.

The ADA tie matters for transportation companies. Under 49 CFR 37.103, when a private firm whose main business is transporting people runs demand responsive service, any new van or bus it acquires has to be accessible, unless the system as a whole meets the equivalent service standard in 49 CFR 37.105.

The IRS notes that an eligible business can take the credit in every year it has access spending. The credit goes on Form 8826 and then on Form 3800, the general business credit form. Partnerships and S corporations report it on Schedule K.

Using both on one conversion

You can claim both in the same year when the spending meets both sets of rules. The IRS puts it plainly: the deduction equals your total qualifying spending minus the credit you claim. Section 44 says the same from its side. No deduction or other credit is allowed for the amount of the disabled access credit, and that amount does not add to the van’s basis either.

Here is an example. A company with $850,000 in gross receipts last year pays a converter $12,000 to install a lift and four-point securement in a van it already owns.

1. Credit. $12,000 minus $250 is $11,750, which Form 8826 caps at $10,000. Half of that is a $5,000 credit.
2. Deduction. $12,000 minus the $5,000 credit leaves $7,000, which fits under the $15,000 Section 190 cap.
3. Depreciation. Nothing from the conversion is left to depreciate.

A larger job changes step 2. On a $25,000 conversion, the credit is still $5,000, the Section 190 deduction stops at $15,000, and the last $5,000 goes into the van’s basis to be depreciated.

What happens to amounts over the limits

The two limits behave differently:

• Section 190. The cap applies per tax year, and it is not a carryforward. Costs above it are capitalized, and the regulation expects you to keep records of that basis adjustment.
• The credit’s spending cap. It is also per year. Spending above $10,250 in one year does not count toward the next year’s credit.
• An unused credit. If your tax is too low to use the full credit, the unused amount carries back one year and forward up to 20 years under Section 39, like other general business credits.

Because both limits reset each tax year, the year a conversion is paid for matters. Two vans converted in different tax years can each support a full credit, while two in the same year share one.

How the breaks fit with depreciation and Section 179

A van and its conversion are depreciable property, and the accessibility breaks sit on top of that. IRS Publication 946 says depreciable basis is reduced by any barrier removal deduction and any disabled access credit, so the same dollars are never written off twice.

First-year write-offs are generous right now. Publication 946 says property that qualifies gets a 100 percent special depreciation allowance when it was both bought and put to use after January 19, 2025, unless you elect out. For tax years beginning in 2026, Section 179 tops out at $2,560,000, phased down once purchases pass $4,090,000. For a van you buy and convert in the same year, depreciation alone may already write off the whole conversion in year one. The credit still adds value, because it cuts tax dollar for dollar where a deduction only cuts it by your tax rate.

Two depreciation rules carry over to these vans:

• Business use. Publication 946 does not treat a vehicle that carries people for hire as a passenger automobile, but a van doing that work still counts as listed property. It has to be used for business over half the time to qualify for Section 179 or special depreciation.
• Recapture. Section 1245 treats a Section 190 deduction like amortization, and Publication 946 lists barrier removal deductions among expensed costs recaptured as depreciation. Selling the van for more than its reduced basis turns that part of the gain into ordinary income. For the sale itself, read how to sell a used wheelchair van.

The NEMT tax basics guide walks through depreciation on a whole van with a worked example.

A van you convert vs one bought converted

The wording of both provisions favors a separate conversion job on a van already in your fleet. Section 190 counts only costs of removing an existing barrier and excludes costs tied to building a vehicle. The credit’s barrier removal category excludes facilities placed in service after November 5, 1990, though its equipment category has no such limit.

A van bought already converted from a mobility dealer raises questions under both. Before you count on either break for one:

1. Ask the seller to invoice the conversion separately from the chassis, with the VIN on both.
2. Keep the conversion’s labels and documents. The conversion guide explains the alterer and lift certification labels.
3. Have your preparer decide, in writing, which costs qualify and under which provision.

Records to keep

The Section 190 regulation asks for records of all the facts behind the deduction, including plans, contracts, and permits, plus the amount of any basis adjustment for costs above the cap. Form 8826’s instructions say records must be kept as long as their contents may matter for the tax. For a van conversion, that means:

• The converter’s itemized invoice with the VIN, and proof of payment.
• The work order describing what was installed: lift or ramp, securement, belts, lowered floor.
• The prior year’s gross receipts and full-time employee count, to show you qualify for the credit.
• Any automaker reimbursement for the same work. Publication 946 lists rebates among the events that adjust basis, and the mobility rebate guide lists the programs.
• Mileage and trip records that show the van’s business use.

Keeping the trip record that backs up business use

First-year write-offs on a van depend on business use above 50 percent, so a dated record of the van’s work is worth having. HealthRide records every trip with GPS-recorded miles and timestamps, and you can hand your preparer the trip log as a CSV or PDF export. See reports.
