Free South Dakota Motorcycle Bill of Sale
South Dakota gives motorcycle buyers 45 days — mirroring its famously relaxed vehicle timeline — and a clean, single-number tax: 4% motor vehicle excise on the purchase price, with no county or city able to add a cent. The transfer runs through the county treasurer of the buyer's county of RESIDENCE (not where the bike is garaged) using Form 1001, the same title and registration application every South Dakota vehicle files, plus the Form 1025 bill of sale. No safety inspection, no emissions test — the physical bike never has to prove anything, only the paperwork does.

South Dakota Motorcycle Bill of Sale — What You Need to Know
Sales Tax Details
Same 4% excise tax on motorcycle purchases. No local add-on.
South Dakota Motorcycle Sale — Step-by-Step Checklist
- Verify the frame VIN against the South Dakota title before paying.
- Complete the Form 1025 bill of sale and Form 1001 application with VIN, year, make, model, odometer, price, and date.
- Seller signs the title over with the odometer disclosure.
- Buyer files at the county treasurer of their county of RESIDENCE within 45 days.
- Buyer pays the 4% motor vehicle excise tax — flat, with no local additions anywhere in South Dakota.
- No inspections to schedule — South Dakota tests neither safety nor emissions on motorcycles.
- Buyer: hold South Dakota's motorcycle endorsement before riding.
Common Pitfalls
- Filing in the county where the bike lives rather than where YOU live — South Dakota routes transfers through the buyer's county of residence.
- Assuming the long 45-day window means no urgency — interest and penalties attach once it lapses.
- Adding imaginary local tax — the 4% excise is the entire bill statewide.
- Declaring a nominal price — the 4% is owed on the total price paid, and without a bill of sale the treasurer assesses it on dealer-guide retail value.
Pro Tip
SD motorcycle: Form 1001 + Form 1025 + county treasurer + 45-day + 4% excise tax.
