Calculate Dallas sales tax
Dallas levies a combined 8.25% sales tax, which is also the maximum allowed anywhere in Texas. It blends the 6.25% state rate with a 1% City of Dallas rate and a 1% levy for Dallas Area Rapid Transit (DART). This calculator turns any pre-tax price into the tax owed and the final total.
How it works
The combined rate is applied to the taxable amount, and exempt items (such as unprepared groceries or prescription drugs) are zeroed out:
taxable amount = exempt ? 0 : purchase amount
tax = taxable amount * (rate / 100)
total = purchase amount + tax
The default rate already merges the Texas state, city, and DART shares. Because Texas caps the combined rate at 8.25%, no Dallas address charges more — the field is editable only so you can model a lower special-district rate.
Tips and example
A 100 purchase at 8.25% incurs 8.25 in tax for a 108.25 total. Toggle the
exemption on for a 100 grocery purchase and the tax drops to 0, keeping the
total at 100. Remember that prepared food and restaurant meals do not qualify
for the grocery exemption, so leave the toggle off for a dine-out bill.
