GMC Sierra 1500 Lease Deals near Renton & Seattle, WA

Below are the Sierra 1500 lease offers running at Brotherton Buick GMC right now. They come from our live inventory rather than a figure typed into a page months ago, so what you see is what is actually on the lot in Renton today.
Underneath them is the part most lease pages leave out: what sits behind the monthly number, how Washington taxes a lease differently from a purchase, and how to work out whether leasing a truck suits you at all. If it does not, we would rather say so here than after you have driven over.
Current Sierra 1500 Lease Offers
Offers change monthly and attach to specific trims, cab and bed configurations and stock numbers. If nothing below matches the truck you want, call 425-336-4655 before making the trip, because Sierra allocation moves quickly and the one that fits your spec may be inbound rather than on the ground.
You can also see everything running across the range on our Buick and GMC lease deals page and on current specials and savings.

What Actually Sets a Sierra 1500 Lease Payment
An advertised monthly figure on its own tells you very little. Four things set it, and only one is the sticker price.
The residual value. What the truck is projected to be worth when the lease ends. It does more to shape your payment than almost anything else, which is why two trucks at similar prices can lease very differently, and why a cheaper truck is not automatically a cheaper lease.
The money factor. The lease equivalent of an interest rate. It moves with your credit, so it is worth getting pre-approved before you negotiate rather than finding out where you stand at the desk.
Term and mileage allowance. A longer term lowers the monthly figure and raises what you pay overall. Mileage gets its own section below, because around here it decides more deals than people expect.
What you put down. Money down lowers the payment but buys you no equity, and if the truck is written off early you can lose it. Plenty of dealers will not volunteer that.
Before you sign anything, anywhere, ask for six figures in writing: selling price, residual value, money factor, term, mileage allowance and an itemized list of fees. A dealership that will not put those on paper is telling you something useful.
How Washington Taxes a Lease, and Why It Changes the Math
This is the part that genuinely differs from most of the country, and it is worth understanding before you compare a Washington quote against a national advertised payment.
Washington does not charge retail sales tax on the full value of a leased vehicle up front. The state Department of Revenue treats a lease as a series of separate sales, with tax due on each payment as it comes due. Any capitalized cost reduction you pay at signing is taxed as its own item at that point.
Two practical consequences follow.
Your local rate follows the truck, not the dealership. For a lease longer than a day or a week, the local rate applied to your payments is the one for the place the vehicle is usually kept, rather than where you signed. A Renton buyer and a Seattle buyer can therefore pay different tax on identical trucks from the same lot, and the dealer's own location is used for the down payment rather than the monthly figure.
A trade-in can reduce the sales tax on a lease. Where a trade allowance is applied to the capitalized cost reduction, tax generally is not due on that portion. That makes getting your trade appraised first worth more here than a quick valuation implies.
We are not tax advisers and the rules carry conditions this summary does not cover, so ask us to work the tax out for your own address before you commit, and check the Department of Revenue guidance or a professional if your situation is unusual.
Mileage, and Why It Matters Around Puget Sound
Standard allowances are commonly 10,000 or 12,000 miles a year. That suits plenty of drivers until the commute is honest about itself.
A daily run from Renton into Seattle, or north on I-405 to Bellevue, adds up faster than people estimate. Add weekend trips over the passes, a boat in summer or a jobsite that moves, and the allowance is gone well before the term is. Buying extra miles at signing costs less than paying the overage at the end, every single time.
Work out your genuine annual mileage, not the figure you would like it to be. Above roughly 15,000 miles a year, buying usually beats leasing, and we will tell you that rather than write the lease.
Lease or Buy a Sierra 1500?
Leasing tends to suit you if you want a newer truck every few years, your mileage is predictable, you want the whole term covered by factory warranty, or you are running the truck through a business.
Buying tends to suit you if you cover a lot of miles, you modify your trucks, you work the bed hard enough that wear charges would bite, or you simply want the payments to stop one day. Full-size trucks hold their value unusually well in the Pacific Northwest, which strengthens the case for buying more here than it would in most of the country.
Anyone who gives you a universal answer without asking about your mileage first is guessing.
Sierra 1500, 2500HD or Sierra EV?
Most leases on this lot are written on the Sierra 1500. The range runs from the work-focused Pro at one end to Denali at the other, and the trims in the middle usually lease best because they hold value without carrying top-of-range monthly cost. What we have on the ground changes weekly, so check inventory rather than the brochure. Our Sierra 1500 research page covers the trims in detail.
The Sierra 2500HD and Sierra 3500HD are bought more often than leased, because people who need a heavy-duty truck usually keep it longer than a lease term and work it harder than a mileage allowance tolerates. Our Sierra 1500 against Sierra 2500HD comparison is the place to start if you are between the two.
The Sierra EV is where leasing makes the strongest case. Electric trucks are early in their product cycle and the technology is still moving, so a lease leaves the resale risk with us instead of with you.
Before You Come In

- Browse new GMC inventory to see what is physically here
- Ending an existing lease? Start with our lease return page
- Call 425-336-4655 and we will have the truck out and ready rather than hunting for keys when you arrive

GMC Sierra 1500 Lease FAQs
How much does it cost to lease a GMC Sierra 1500 near Renton, WA?
It depends on the trim, the configuration, the term, the mileage allowance and your credit, and offers change monthly, so the live list above is the accurate answer at any given moment. Tell us the truck you are looking at and your address and we will produce the real figure including Washington tax and your trade, rather than a headline payment that applies to one stock number.
Do I pay Washington sales tax on the whole truck when I lease?
No. Washington treats a lease as a series of separate sales, with retail sales tax due on each payment as it falls due, plus tax on any capitalized cost reduction paid at signing. For leases beyond a day or a week the local rate is the one for where the vehicle is usually kept rather than where the dealership sits, so two buyers can pay different tax on identical trucks.
Does a trade-in reduce tax on a lease in Washington?
It can. Where a trade allowance is applied to the capitalized cost reduction, sales tax generally is not due on that portion. The rules carry conditions, so have us work it out for your specific deal rather than assuming a figure.
Is it cheaper to lease or buy a Sierra 1500?
Mileage usually decides it. Leasing tends to win on predictable mileage, a newer truck every few years and full warranty coverage throughout. Buying tends to win above roughly 15,000 miles a year, if you modify the truck, or if you work it hard enough that wear charges would be a factor.
How many miles should I put on a Sierra lease in the Seattle area?
More than you first think. A Renton to Seattle commute, I-405 traffic, weekends over the passes and any towing all draw on the allowance. Buying additional miles at signing costs less than paying the overage at lease end, so start from your real annual mileage.
What should I have in writing before signing a lease?
The selling price, the residual value, the money factor, the term, the mileage allowance and an itemized list of fees. Those six figures produce the payment. A monthly number quoted without them tells you almost nothing.
