There's more than one way to claim your Missouri motor fuel tax refund. Here's an honest look at the main options drivers actually use, so you can pick the one that fits how much manual work you're willing to do.
FuelBack MO
FuelBack MO pulls the details off each receipt automatically, autofills a missing address or zip code, keeps a running total of your fuel usage all year, and lets you export everything as a CSV whenever you want.
It completes your Form 4923-H packet and drafts the submission email for you — you just review it and click send. It's a flat $14.99, not a cut of your refund, and you can try it free first.
MOGasTaxBack
MOGasTaxBack does have real filing functionality built in — it can help track and prepare your claim. But it charges 10-20% of your refund amount, which can add up to a meaningful cut of the money you're claiming back.
The app itself also isn't very intuitive to use, and it doesn't file for you automatically. You have to request the app creator process your data and return the completed form — you still have to submit it yourself.
NOMOGasTax
NOMOGasTax is really just a receipt tracker — there's no filing functionality at all.
You enter every receipt manually, and the interface is clunky. It can help you keep records, but it doesn't get you any closer to actually submitting a claim.
Filing the DOR form yourself (PDF)
Filing the DOR paper form works, and it's free and official. But it puts all the work on you.
You have to keep track of every receipt yourself, dig back through them for missing details like the station, gallons, and date, figure out which receipt belongs to which vehicle (usually by writing it on the receipt by hand), and key every line into the form manually.
You can download the official Form 4923-H PDF directly from the Missouri DOR, and the DOR also has a walkthrough video on how to fill it out if you'd rather follow along step by step.
The DOR Excel template
The Excel template carries the same manual burden as the PDF — you're still tracking, sorting, and keying everything in by hand.
On top of that, you can't just download it. You have to request the template through the Missouri DOR's MyTax portal before you can even start.
