Idaho RV Registration: The Fee Breakdown
Idaho actually charges two separate components, not a simple weight fee: an age-based base fee ($69 for 1-2 yrs old, $57 for 3-6 yrs, $45 for 7+ yrs) plus a value-based 'recreational vehicle' fee ($8.50 for the first $1,000 of taxable RV value, +$5 per additional $1,000, using only the 'recreational' portion of value — roughly 25%-60% for motorhomes). The figure shown here blends both into a single estimate using a mid-range age and value factor; your exact fee depends on both your RV's age and its taxable value, so use Idaho's own fee estimator for a precise number. All Idaho RV registrations expire December 31 regardless of when you register.
| Fee Component | Amount |
|---|---|
| Base Registration Fee | $57 |
| Value-Based Fee | 0.340% of 40% of current RV value |

Is Idaho a Full-Timer Domicile State?

Frequently Asked Questions — Idaho RV Registration
How much does it cost to register an RV in Idaho?
In Idaho, RV registration combines a base fee with a percentage or bracket tied to your RV's value, so the total varies with what your RV is worth. Use the calculator above for a personalized estimate, and always confirm the current fee with your state DMV before registering. Given some uncertainty in the exact published figures for this state, please double-check the current rate with your state DMV before budgeting precisely.
Is Idaho's RV registration fee based on weight, value, or a flat rate?
Idaho uses a value-based fee — you pay a $57 base fee plus roughly 0.340% of your RV's current value each year. This means the fee is highest when your RV is new and declines as it depreciates. It does not depend on the RV's weight.
Does Idaho have a state income tax?
Yes, Idaho levies a state income tax. If minimizing overall tax burden as a full-time RVer is your priority, states with no income tax (like South Dakota, Texas, Florida, Nevada, or Wyoming) are usually a better domicile choice, even if their registration fee is higher.
Is Idaho a good state for full-time RVer domicile?
Idaho 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.
