What is SlimTax?

SlimTax uses AI-powered technology to help Wake County residents quickly and easily appeal their vehicle property tax valuations. We work directly with the county to reduce your tax bill, saving you money without the hassle.

How does it work?

It’s simple:

1. Submit your vehicle information (it takes less than 60 seconds).

2. Our team updates your vehicle’s appraisal and files an appeal with the county.

3. You’ll receive a new tax bill, usually about two weeks before your registration expiration date (if submitted 30+ days in advance).

How much can I expect to save?

On average, our customers save 20% or more on their vehicle property tax bills. Savings vary based on the original county valuation and vehicle condition.

When should I submit my order?

We recommend submitting your appeal at least 30 days before your vehicle registration expiration date.
This gives the county enough time to review and adjust your bill before renewal deadlines.

What happens after I submit my information?

After you check out, you’re all set!
Our team reviews your information, prepares your updated appraisal, and files the appeal with the county. We'll notify you once your appeal is submitted, and you’ll receive your updated tax bill directly from the county if the appeal is approved.

What if my appeal is denied?

SlimTax works hard to build strong appeals, but if the county denies the adjustment and we can't lower your bill, you don't owe us anything.
That's part of our Savings and Satisfaction Guarantee.

Is my information secure?

Yes. We take your privacy and security seriously. Your personal and vehicle information is encrypted and only used to file your appeal with the county.
