How do you set up sales tax on a POS system?

Short answer: Confirm the combined state and local rate for each location with your state revenue department, enter it as a tax rate in the POS, then assign it to taxable items and exclude exempt ones. Test a few receipts, and check the sales tax report against your filing each period. Rates and rules change, so review them at least yearly.

Key facts

  • Confirm rates with your state revenue department
  • Assign tax to items, not just the register
  • Mark exempt items explicitly
  • Reconcile the tax report before each filing

The short version

Merchant Fund Express explains payments in plain English so owners can make better decisions about equipment and processing.

Sales tax mistakes add up quietly. Setting rates and taxable items correctly at the start saves corrections later.

A POS can apply sales tax automatically, but only as accurately as it is set up. You choose the tax rates for your location and which items are taxable, exempt or taxed differently, such as prepared food versus groceries in some states.

Rates and rules vary by state, county and city and can change. Confirm the correct rates and taxability with your state tax agency or accountant, then check your reports regularly. This is general information, not legal or tax advice.

The steps

Find your rates

Look up the combined rate for each location you sell from.

Mark items

Set each item as taxable, exempt or a different rate.

Test a sale

Ring test items and check the tax on the receipt.

Review reports

Compare sales tax collected with your filings each period.

Tips that help

Mobile sellers may need different rates at different events or cities.
Tax-exempt customers need documentation on file.
Update rates when your state announces a change.

A worked example

A coffee cart sells at three farmers markets in different cities. The owner sets up a tax rate for each city, checks a test receipt at each market and reviews the monthly sales tax report before filing.

Who will use this, and how long will it take to train them?

Questions worth asking your processor

What happens to this if my monthly volume doubles or halves?
Where on the statement will I see this, and under what label?
What do I need to keep as a record if a charge is questioned?
Is there a limit or a review that this could trigger as my volume grows?
