Sales tax mistakes are common among craft fair vendors — not because vendors are careless, but because the rules are genuinely confusing and the stakes feel low until they suddenly don't. Here are the five most common errors and how to fix them.
Mistake 1: Using the Wrong Rate
State rates are just the starting point. Most states allow counties and cities to add their own sales tax on top of the state rate. A vendor selling in a city with a 1.5% local add-on who's only charging the state rate is undercharging — and eating the difference out of their margin.
Fix: Look up the combined rate for the specific venue location, not just the state base rate. salestaxowed.us shows the current state rate and accounts for common local additions. For shows in specific high-tax cities, verify with the city revenue department.
Mistake 2: Assuming Handmade = Exempt
Some vendors believe that because they made something by hand, it isn't subject to sales tax. This is almost never true. In most states, tangible personal property is taxable regardless of whether it was mass-produced or crafted individually.
Fix: Assume your goods are taxable unless you have a specific reason to believe otherwise (your state explicitly exempts the category, or you've confirmed it with the revenue department). Don't let the handmade nature of your work create a false sense of exemption.
Mistake 3: Collecting But Not Remitting
Some vendors collect sales tax from customers — they add it to the price, they see it in their totals — but never actually file a return and send it in. This is arguably worse than not collecting at all: you've taken money from customers with the explicit purpose of sending it to the state, then kept it.
Fix: Once you register for a sales tax permit, put the filing deadline in your calendar. Most states have you file quarterly or annually. The amounts are usually small; the act of filing is what matters.
Mistake 4: Not Registering Before the First Sale
In most states, the registration requirement kicks in before you make your first taxable sale — not after. Showing up at a show without a permit and collecting tax anyway is technically operating as an unregistered business.
Fix: Register before you do your first show in any new state. Many states offer free registration and quick online processing. Some markets even require proof of a sales tax permit to participate — getting registered early means you're not scrambling the week before the show.
Mistake 5: Charging Tax on Non-Taxable Items
This one goes the other way. Some vendors apply their standard tax rate to everything without realizing that certain items — some food products, some clothing in specific states — may be exempt. Overcharging customers isn't just an ethics issue; it can create problems if a customer requests an itemized receipt or a refund of improperly collected tax.
Fix: Know the exemptions in the states where you sell. If you carry a mix of taxable and non-taxable goods (say, homemade baked goods alongside candles), track them separately at the register. Most payment apps let you create different tax categories per product.
The Simplest Fix of All
Most of these mistakes come from uncertainty. The more clearly you understand the rates and rules for the specific states where you sell, the harder it is to get them wrong. Use salestaxowed.us to confirm your rates before each show, and reversesalestax.us when you need to work backwards from a tax amount to the original price.
