Frequently Asked Questions
How do I calculate sales tax?

Multiply the pre-tax price by the tax rate divided by 100. For example, a 50 dollar item with 8 percent sales tax costs 50 times 0.08, which is 4 dollars in tax, for a total of 54 dollars. This calculator does the math automatically.

What is the difference between sales tax and VAT?

Sales tax is applied only at the final point of sale to the consumer. VAT, or value-added tax, is applied at each stage of production and distribution. The US uses sales tax, while most other countries use VAT systems.

Are all items subject to sales tax?

No, tax rules vary by state and locality. Many states exempt groceries, prescription medications, and certain clothing items from sales tax. Check your state department of revenue website for the specific exemptions that apply in your area.

Do I pay sales tax on online purchases?

Most US states now require online retailers to collect sales tax on purchases shipped to their state. This is based on the destination address. Some small sellers may not collect tax, in which case you may owe use tax when you file your state return.

How often do businesses remit sales tax?

Remittance frequency depends on sales volume and state requirements. Most businesses file monthly or quarterly. High-volume sellers may need to file monthly, while smaller businesses might file quarterly or annually. Check with your state revenue agency for your specific filing schedule.
