FIN-320 vs FIN-355 BC: Which PST Form Do You Need?
These two BC tax forms solve different problems. FIN-320 helps before registration when a vehicle’s documented value is lower. FIN-355 is the refund path after PST has already been paid.
Why buyers use this page
- Use FIN-320 before registration when the vehicle is worth less than the value being used for tax paperwork
- Use FIN-355 after PST was already paid and you need to request a refund review
- Some cases need both forms because the refund file still needs value support
- Best for private-sale buyers, high-mileage vehicles, damaged vehicles, and refund situations
FIN-320 vs FIN-355 BC
Most buyers do not need more paperwork — they need the right paperwork at the right stage. The easiest way to remember the difference is this: FIN-320 is the valuation form that helps before or at registration, while FIN-355 is the refund form used after PST has already been paid.
Why buyers get this wrong
The form names are easy to find, but the timing is what usually causes confusion. Buyers often see FIN-320 and FIN-355 before they understand which one fits their situation, whether value support should be prepared before registration, and what proof is needed for a refund file.
The simplest decision rule
If the vehicle is not registered yet and its real value is lower than the broker’s reference value, start with a FIN-320 appraisal before you pay PST.
If PST was already paid and you now need a refund review, move to the FIN-355 path with matching proof of purchase and supporting documents.
If the refund depends on showing the vehicle was worth less than the number used for tax, the FIN-320 becomes supporting evidence inside the FIN-355 package.
FIN-320 vs FIN-355 BC FAQ
What is the biggest difference between FIN-320 and FIN-355?
FIN-320 is the appraisal form used to support a lower vehicle value, usually before or at registration. FIN-355 is the refund application used after PST has already been paid.
Do I ever need both FIN-320 and FIN-355?
Yes. If PST was already paid and you now need a refund review because the vehicle was worth less than the value used for tax, FIN-355 is the refund path and FIN-320 can be the valuation support inside that file.
If I have not registered the vehicle yet, which form should I think about first?
Usually FIN-320. Solving the value question before registration is cleaner than paying first and trying to adjust the file later.
Can I file a FIN-355 refund with weak proof of purchase?
That is where many refund files break down. You want payment proof that matches the amount, timing, and seller identity, plus valuation support when the refund depends on the vehicle being worth less.
Who should read this page most carefully?
Private-sale buyers, drivers with high-mileage or below-average vehicles, and anyone who already paid tax and is now trying to decide whether they need an appraisal, a refund application, or both.
