Lease vs. Buy in Illinois, at a Glance
Most articles on whether to lease or buy a Nissan cover the same generic ground: mileage limits, equity, monthly payments. What they skip is that Illinois taxes the two options differently, and those rules can change the math in ways nobody mentions until you’re at the signing table. Here’s how it works for drivers in Skokie, the North Shore, and Chicago.
| In Illinois | Buying | Leasing |
|---|---|---|
| Illinois tax is based on | The full purchase price | The amount due at signing plus all lease payments |
| Trade-in reduces the taxable amount? | Yes, with no dollar cap (since 2022) | No, for a standard lease longer than one year |
| Chicago’s lease tax can apply? | No — it’s a lease tax | If the vehicle is used primarily in Chicago |
| Mileage limit? | None | Set by the lease contract |
| You build equity? | Yes | No — you’re paying for use, not ownership |

Why Illinois Taxes a Lease Differently
When you buy a car in Illinois, sales tax applies to the full purchase price. When you lease, the state taxes a different number: the amount due at signing plus the total of your lease payments over the term. That rule has applied since January 1, 2015, when Illinois changed how it defines a lease’s “selling price” for tax purposes. It covers fixed-term leases longer than one year.
Because you’re only paying for the part of the car you use during the lease, the taxable amount is smaller by design. The tax is still calculated when the lease is signed, and it’s often built into the lease rather than paid separately. Charges that come up later, like excess mileage or wear at turn-in, are taxed when you pay them.
The Trade-In Surprise: It Doesn’t Work the Same Way on a Lease
If you buy a car and trade in your old one, Illinois lets you deduct the trade-in’s value from the taxable price. Since January 1, 2022, there’s no dollar limit on that deduction. Before that, for 2020 and 2021, the credit was capped at $10,000.
Lease the same car, though, and the trade-in doesn’t reduce the tax. Under the lease method, the Illinois Department of Revenue doesn’t allow the trade-in credit to lower the taxable amount. Your trade-in can still reduce what you pay at signing or lower your monthly payment, depending on how the deal is structured. It just isn’t doing the same tax-saving job it would on a purchase.
Buying Out a Lease: Why You Pay Tax Twice
Most leases include an option to buy the car at the end of the term, at a price set in your contract. If you take it, the buyout is taxed as a purchase. Illinois doesn’t credit the tax you already paid on the lease against the buyout.
That doesn’t make a buyout a bad idea. If the car has been reliable and the buyout price is fair, keeping it can make sense. But if you already know you want to keep the car for many years, that second round of tax is part of the math to weigh before you choose to lease in the first place.
Leasing in Chicago vs. the Suburbs: Why Where You Drive Matters
Chicago has its own tax on top of the state’s: the Personal Property Lease Transaction Tax. It rose from 11% to 15% on January 1, 2026, and it can apply to vehicle leases. What matters is where the lease is signed and where the vehicle is primarily used, not just how close the dealership is to the city line.
If you live in Skokie, Niles, Evanston, Morton Grove, Des Plaines, Glenview, Lincolnwood, or Wilmette, all separate municipalities from Chicago, and you lease from us and drive the car mostly outside the city, the Chicago tax generally doesn’t apply. If you live in Chicago and the car will be used mostly in the city, the tax can apply even on a lease signed in the suburbs. How it’s handled depends on your lease, so ask our finance team to walk through it before you sign.
Beyond Taxes: What Changes Between Leasing and Buying
A lease comes with a mileage limit. Go over it, and you pay a per-mile charge at turn-in: overage charges are set by your lease contract — commonly in the 15 to 25 cents per mile range. That matters if your commute, or regular trips up to Wisconsin or out to the western suburbs, puts more miles on a car than average. Buying has no mileage limit at all.
Most leases end before the factory warranty does. That means covered repairs during the lease are less likely to come out of your pocket. Routine maintenance like oil changes and tires is still on you either way. When you buy, you keep the car, and its upkeep, long after the warranty runs out.
At the end of a lease, you return the car or buy it out. A purchase ends with a car you own outright and no payment at all once it’s paid off.
Which One Fits How You Drive?
The Illinois rules above point in clear directions, depending on your situation.
Leasing tends to fit if:
- You want a lower amount due at signing and a shorter commitment.
- You drive a predictable, moderate number of miles each year.
- You like being in a newer Nissan every few years, under factory warranty.
- You live and drive mostly outside Chicago, so the city’s lease tax isn’t part of your math.
Buying tends to fit if:
- You have a trade-in with real value and want it to lower your tax bill.
- You drive a lot of miles, or your mileage is hard to predict.
- You plan to keep the car well past the length of a typical lease.
- You’d rather not pay tax twice by leasing first and buying out later.
