Overview
A TRAC lease is a truck or trailer lease that fixes a residual value at signing and settles the difference when the vehicle is sold at the end. If the sale beats the residual, money comes back to you. If it falls short, you pay the gap.
That trade can lower the monthly payment compared with a loan on the same truck. The resale risk stays with you, though. This guide covers the clause under federal law, two worked examples on one tractor, and the contract points to check before you sign.
What is a TRAC lease?
A TRAC lease is a vehicle lease that sets a residual value at signing and adjusts the final rent up or down based on what the vehicle sells for at the end. TRAC stands for terminal rental adjustment clause, the contract term that does the adjusting.
The structure is built for road vehicles. Under 26 U.S.C. §7701(h), the tax rule for these leases covers a motor vehicle, including a trailer. A tractor or a reefer trailer fits. Machinery that is not a motor vehicle does not.
A TRAC lease is one of several ways to pay for a truck. Our guide to semi truck financing sets loans, leases and carrier programs side by side.

How the terminal rental adjustment clause works
The terminal rental adjustment clause is the part of the lease that moves your final rent with the truck's sale price. Per Section 7701(h)(3)(A), it is a provision that lets or requires the rent to be adjusted upward or downward. The reference point is the amount the lessor realizes when it sells or otherwise disposes of the vehicle.
Three figures decide how the contract ends:
- Residual: a dollar value for the truck at the end of the term, written into the lease at signing.
- Sale proceeds: what the truck brings when it is sold after you turn it in.
- Adjustment: the gap between the two, settled in cash.
If the truck sells above the residual, the lessor refunds the difference to you as a rent reduction. If it sells below, you pay the shortfall as extra rent.
Either way, the residual value risk sits with you. The lessor has set its number at signing. You carry the market.
The split is not fixed by law. Your contract decides whether you get the whole gain, who runs the sale and what costs come off first. Read that section line by line.
Worked example: settling the residual when the truck sells
Methodology: Commera illustrative calculation with assumed figures, not an offer and not a real deal. The example lease passes the whole difference between sale proceeds and the residual to the lessee. No sale costs are deducted. Payments, fees and APR for the same lease are in the next worked example.
Here is how one residual plays out in two markets.
- At signing, the illustrative lease sets the residual at $32,000, and your monthly payment is priced around it.
- In a strong market, the tractor sells for $40,000, and the lessor refunds the $8,000 difference to you.
- In a weak market, it sells for $25,000, and you pay the lessor the $7,000 gap.
In this illustrative case, the monthly payment was the same both times. Only the sale price changed, and it moved your final bill by $15,000.
A residual is not a discount. It is a bet on the truck's future value, and you are the one placing it.
Worked example: what a TRAC lease costs on a $160,000 tractor
In a Commera illustrative calculation, a TRAC lease on a new tractor asks for no down payment and costs about $176 a month less than a loan. The price is the residual you still face at the end. The tables below show the full lease and a loan on the same truck.
Methodology: Commera illustrative calculation with assumed inputs, not an offer, not a quote and not a real deal. Both deals run 48 months. The lease has monthly payments in advance, the first at signing, priced at an implicit rate of 9.50% chosen to build the example. The implicit rate is not an APR.
In this illustrative setup, the lease has a documentation fee at signing, no security deposit and no mandatory end-of-term fees. The loan has 10% down, the same rate as a fixed annual rate, payments in arrears and the same documentation fee. The estimated APR is an IRR on the dated cash flows named below each table. All terms are subject to underwriting.
| Lease item | Amount, $ |
|---|---|
| Equipment cost, new tractor | 160,000.00 |
| Due at signing: first monthly payment | 3,441.85 |
| Due at signing: documentation fee | 395.00 |
| Refundable security deposit | 0 (none in this example) |
| Monthly payment, in advance | 3,441.85 |
| Mandatory contract payments (fee and all monthly payments) | 165,603.80 |
| Mandatory end-of-term fees | 0 |
| TRAC residual, 20% of cost | 32,000.00 |
Mandatory contract payments count the first payment once. They exclude the residual, which you pay only if you buy the truck.
The end of the contract follows the TRAC clause from the previous example. Three outcomes are possible:
| End of the lease | TRAC adjustment, $ | Lessee's net cost over the term, $ | Est. APR, % | Lessee owns the truck? |
|---|---|---|---|---|
| Truck sells for $40,000 | 8,000 refunded to lessee | 157,603.80 (cost of leasing) | Not calculated | No |
| Truck sells for $25,000 | 7,000 paid by lessee | 172,603.80 (cost of leasing) | Not calculated | No |
| Lessee buys at the residual | 0 | 197,603.80 (acquisition cost) | About 9.62 | Yes |
For the two sale outcomes, the table shows the cost of leasing over the term, not an APR. That cost depends on a sale price nobody knows at signing. The acquisition cost is the mandatory payments plus the residual paid to buy the truck.
Its est. APR is an IRR on these flows: the tractor's price received at signing, the first payment and fee paid that day, 47 more monthly payments, and the residual paid at the end of the term.
Now the loan on the same tractor:
| Loan item | Value |
|---|---|
| Down payment, 10% | $16,000.00 |
| Loan amount | $144,000.00 |
| Rate, fixed annual | 9.50% |
| Term | 48 months |
| Monthly payment | $3,617.73 |
| Total repayment, all monthly payments | $173,651.04 |
| Documentation fee at closing | $395.00 |
| Est. APR, with the fee | About 9.64% |
| Total cash out: down payment, fee and payments | $190,046.04 |
| Who owns the truck | You, with the lender's lien until payoff |
Total repayment uses the rounded payment. The loan's est. APR is an IRR on the loan amount less the fee at closing, then the monthly payments in arrears. A rate is not an APR.
In this illustrative comparison, the lease wins on cash at the start: no down payment and about $176 a month less. The loan wins if you want to keep the truck. Buying at the residual makes this example lease $7,557.76 more expensive than the loan, at $197,603.80 against $190,046.04.
A lease you walk away from is not the same as a loan you own. The loan total buys a tractor that still has resale value. To test your own figures, estimate a payment before you compare quotes.
A lease is not a loan; ownership, tax treatment and end-of-term obligations depend on the lease type and the specific contract. Consult a tax advisor.
TRAC lease vs FMV lease vs $1 buyout
A TRAC lease, an FMV lease and a one-dollar buyout lease differ mainly in who carries the truck's resale risk at the end. Each one ends in a different way, too.
| Lease type | Who carries resale risk | How it ends |
|---|---|---|
| TRAC lease | Lessee, through the final rent adjustment | The truck is sold and the gap to the residual is settled, or the lessee buys at the residual if the contract allows |
| FMV lease | Lessor | The lessee returns the truck or buys it at fair market value at that time |
| $1 buyout lease | Lessee, as with a purchase | The lessee pays the nominal buyout and owns the truck |
State law draws its own line between a lease and a purchase. Under UCC §1-203, whether a lease is a true lease or a security interest depends on the facts of each case.
A lease that lets you become the owner for no or nominal extra payment creates a security interest. That is the $1 buyout pattern, and it works like a purchase on installments. By contrast, per UCC §1-203(c)(6), an option to buy at a fixed price at or above the reasonably predictable fair market value does not, by itself, create a security interest.
State law on TRAC leases can differ, so ask an attorney how your state treats the contract. For the wider choice between buying and leasing, see our equipment financing guide.
What the tax and legal labels mean for you
For federal income tax, a qualifying TRAC lease stays a lease. Per Section 7701(h)(1) of the Internal Revenue Code, an agreement with a TRAC is treated as a lease if it would be a lease without the clause. The lessee is not treated as the owner while the agreement is in effect.
Not every contract qualifies. Per Section 7701(h)(2)(C), the lease must include a separate written statement, signed separately by the lessee.
In it, per Section 7701(h)(2)(C)(i), you certify under penalty of perjury that you intend more than 50% of the truck's use to be in your trade or business. The same statement must say you were advised that you will not be treated as the owner for federal income tax purposes. Section 7701(h)(2)(B) adds a minimum liability test for the lessor's own borrowing, which is the lessor's side of the deal.
Which deductions you can take follows from that label and your own situation. Consult a tax advisor before you sign.
Consumer lease rules will not help you here. Under Regulation M, 12 CFR 1013.2(e)(1) defines a consumer lease as one to a natural person primarily for personal, family or household purposes. A TRAC lease on a work truck is a business lease. Regulation M consumer lease disclosures do not apply, so everything you need is in the contract itself.
A lessor may also file a public notice of its interest in the truck. Our guide to the UCC lien explains what that filing means and how it is released.
This section is general information, not tax or legal advice. Consult a tax advisor and an attorney before you sign.
What to check before you sign a TRAC lease
Before you sign a TRAC lease, check the residual, the sale process and the end-of-term costs. Those terms decide your final bill more than the monthly payment does.
TRAC lease contract checklist:
- Residual in dollars and percent. Ask for both. A higher residual lowers the payment and raises your exposure at the end.
- Who sells the truck. Find out who finds the buyer and how the sale price is set.
- Gain sharing. Check whether a sale above the residual pays you the whole difference or only part.
- Mileage and condition. Read any mileage limits, wear standards and return condition charges.
- End-of-term fees. List every fee due at return or sale, such as disposition or inspection charges.
- Early termination. Ask how the payoff is calculated if you need out before the last payment.
- Purchase price. Confirm whether you can buy at the residual and what else is due at purchase.
- The separate tax statement. Expect a separately signed certification about business use. Read it before you sign it.
Then run the contract the way the worked example does. Add up the mandatory payments, then test a high and a low sale price against the residual.
Put a loan quote next to the lease quote and compare lease and loan offers on the same truck and term. For cash flow needs beyond the truck itself, see how financing works for trucking businesses.
