North Dakota's Flat 5% Excise Tax
North Dakota charges a Motor Vehicle Excise Tax of 5% on the vehicle's taxable purchase price, applied uniformly statewide with no city or county add-on. That flat structure makes North Dakota straightforward to budget for — a $30,000 car owes exactly $1,500 in excise tax regardless of location within the state.
Where North Dakota differs from many flat-tax states is registration: rather than a flat annual fee, North Dakota's registration is weight-based, ranging from roughly $49 to $274 per year for passenger vehicles depending on how heavy the vehicle is. Larger trucks and SUVs will land toward the higher end of that range.
North Dakota doesn't cap dealer documentation fees by statute, according to the Automobile Dealers Association of North Dakota, so it's worth asking your dealer directly what they charge.

Trade-In Credit in North Dakota
North Dakota allows a trade-in tax credit: your trade-in value is subtracted from the purchase price before the flat 5% excise tax is calculated. Because the rate doesn't vary by location, savings are simple to estimate — trade-in value × 5%.
On a $10,000 trade-in, that's a flat $500 in excise tax savings no matter which North Dakota county you're registering in.
The main variable cost to plan for beyond the tax itself is registration, since it scales with vehicle weight rather than staying flat — heavier trucks and SUVs will cost noticeably more annually than a compact sedan.
