Worked Example

Let's say you're purchasing a vehicle in Harris County (Houston) for $30,000. The local sales tax rate for Harris County is 2.0%.

Using the formula:

Total Sales Tax = ($30,000 × 6.25%) + ($30,000 × 2.0%) Total Sales Tax = $1,875 + $600 = $2,475

So, the total sales tax for this purchase would be $2,475.
