A new or used car is one of the largest purchases many people will make in their lifetimes, but the costs are almost always higher than the vehicle’s list price. Sales tax, fees, and tariffs add to the expense, and they aren’t always on buyers’ minds when they head to the dealership. This page helps explain some of the fees you might see during your next car purchase, and our in-depth articles detail what you need to know before you start shopping.
Required vs. Negotiable Dealer Fees
Some line items on a car deal are legally required. Others are dealer add-ons you can push back on, reduce, or remove entirely. Here is how to tell them apart.
Often-Required Fees
Government-mandated or contractually standard charges. These are not negotiable on the dollar amount, but you should always verify them.
-
Sales Tax
Set by your state (and sometimes county or city). Rates and rules vary widely – some states use excise or use taxes instead.
-
Doc Fee
Covers paperwork processing. Capped by law in some states; uncapped (and often padded) in others. Check your state’s limit.
-
Destination Fees
Set by the automaker to ship a new car from the factory to the dealer. Same price nationwide for a given model; not a dealer markup.
-
Registration & Title Fees
State charges to title the vehicle in your name and issue plates. Set by your DMV – the dealer just collects and remits them.
Negotiable or Unnecessary Fees
Dealer-added charges that pad profit. You can ask for them to be removed, reduced, or walk away if the seller insists.
-
Market Adjustments / Markups
Dealer-imposed premiums over MSRP on hot vehicles. Pure profit – shop around or wait for supply to normalize.
-
Dealer Prep or Reconditioning
Charges for washing, inspecting, or “preparing” the car. New-car prep is reimbursed by the automaker; used-car recon is a cost of doing business.
-
Accessory Packages / Upgrades
Pre-installed nitrogen, paint sealant, VIN etching, all-weather mats, etc. Often marked up 5-10x. Decline or negotiate to cost.
-
Extended Warranty / GAP
Optional F&I products. Useful for some buyers, but heavily marked up in the finance office. Always price-shop with your insurer or credit union first.
