On a new Mercedes-Benz bought from a Gilbert dealership, taxes and government fees run about 10% of the price in the first year: 8.3% Gilbert sales tax on the price and the documentary fee, Arizona's vehicle license tax at registration ($2.80 per $100 of 60% of the base MSRP), and about $31 in title, processing, and tire fees.
At each model's starting MSRP, that is about $4,990 on a 2026 C-Class, $5,260 on a 2027 GLC, $6,860 on a 2027 GLE, and $9,410 on a 2027 GLS, before the dealership's documentary fee, which Arizona does not cap and which is taxed at the same 8.3%. A trade-in lowers the sales tax; a car shipped out of Arizona carries no Arizona sales tax.
Worked out with The Model Black's tax and fee engine for a Gilbert dealership (ZIP 85297) at each model's starting MSRP, with no trade-in. Options raise the price and the sales tax; the vehicle license tax is figured on the base MSRP, before options. The dealership's documentary fee comes on top, plus 8.3% tax on it. Rounded to the dollar.
| Model, at its starting MSRP | Sales tax at 8.3% | Vehicle license tax, year one | Title, processing, and tire fees | Taxes and government fees |
|---|---|---|---|---|
| 2026 C-Class | $4,121 | $834 | $32 | $4,987 |
| 2027 GLC | $4,349 | $880 | $32 | $5,261 |
| 2027 GLE | $5,677 | $1,149 | $32 | $6,858 |
| 2027 GLS | $7,798 | $1,578 | $32 | $9,408 |
Arizona does not cap dealer documentary fees. The fee is the dealership's own charge, not a government fee, and it is taxed with the sale. Ask for it in writing before you agree on a price, and compare stores on the total out the door, not the price alone. See MSRP, invoice, and out-the-door price.

No. Each dealership sets its own documentary fee, and it is taxed with the sale.
