Kentucky's fee is flat regardless of RV size. Weight-based and value-based states (right) can cost far more for large or expensive rigs.
Kentucky RV Registration: The Fee Breakdown
The $21 state renewal fee (plus county clerk fees) is correct for annual renewal — but since House Bill 360 (effective July 2023), Kentucky's 6% Motor Vehicle Usage Tax now explicitly applies to RVs (motorhomes, travel trailers, 5th wheels, pop-ups with living quarters) at first registration/title transfer. That one-time 6% tax on sale price or NADA value can run into the thousands on a new RV — a far bigger cost than the $21 annual fee, and easy to overlook.
| Fee | Amount | Notes |
|---|---|---|
| State Registration Fee | $21 | Flat, all RV classes and weights |

Is Kentucky's RV registration fee based on weight, value, or a flat rate?

Kentucky isn't typically recommended as a full-timer domicile state. Most full-time RVers instead choose South Dakota, Texas, Florida, Nevada, or Wyoming, which offer a combination of low registration costs, no state income tax, and established mail-forwarding services for establishing residency without a fixed address.
