What Is Sales Tax?
Sales tax is a consumption tax imposed by governments on the sale of goods and services. When you purchase an item, the seller collects the tax from you and remits it to the appropriate government agency. Sales tax rates vary by jurisdiction (state, county, city) and can apply differently to various types of goods and services.
Key characteristics of sales tax:
- Regressive Nature: Sales tax typically represents a larger percentage of income for lower-income households
- Jurisdictional Variation: Rates differ significantly between states, counties, and cities
- Exemptions: Many jurisdictions exempt certain items like groceries, prescription drugs, or clothing
- Destination-Based: Generally applied based on where the buyer takes possession of the goods
Understanding sales tax helps consumers budget accurately and businesses comply with tax regulations.
How Sales Tax Calculation Works
Our sales tax calculator uses a straightforward mathematical formula to determine both the tax amount and total price:
Step 1: Convert Tax Rate to Decimal
Tax Rate (Decimal) = Tax Rate (%) ÷ 100
Step 2: Calculate Tax Amount
Tax Amount = Item Price × Tax Rate (Decimal)
Step 3: Calculate Total Price
Total Price = Item Price + Tax Amount
Example Calculation:
Item Price: $100.00
Tax Rate: 7.5%
Tax Rate (Decimal) = 7.5 ÷ 100 = 0.075
Tax Amount = $100.00 × 0.075 = $7.50
Total Price = $100.00 + $7.50 = $107.50
This calculation provides the exact amount you'll pay at checkout, helping you budget accurately for purchases.

Yes, in most cases you now pay sales tax on online purchases due to the 2018 Supreme Court decision in South Dakota v. Wayfair:
- Nexus Rules: Online sellers must collect sales tax if they have economic nexus in a state
- Economic Thresholds: Typically $100,000 in sales or 200 transactions annually
- Use Tax: If tax isn't collected at purchase, consumers may owe use tax to their home state

Service taxation varies significantly by state and type of service:
- Traditional Services: Haircuts, auto repairs, and similar services are taxable in many states
- Professional Services: Legal, accounting, and consulting services may be exempt in some states
- Digital Services: Streaming services, software, and digital products are increasingly taxed

Taxpayers who itemize deductions can choose between deducting state income tax or state sales tax:
- Itemizing Requirement: Only available if you itemize deductions on Schedule A
- Either/Or Choice: You can deduct either state income tax or sales tax, but not both
- Beneficial For: Residents of states with no income tax or those with major purchases
- Documentation: Keep receipts for major purchases or use IRS estimated tables
- Major Purchases: Vehicles, boats, and home building materials can significantly increase your deduction
With the increased standard deduction from the Tax Cuts and Jobs Act, fewer taxpayers now itemize deductions. Consult a tax professional to determine if sales tax deduction is beneficial for your situation.
Sales tax and Value Added Tax (VAT) are both consumption taxes but work differently:
- Collection Point: Sales tax is collected only at the final sale to consumers; VAT is collected at each stage of production
- Transparency: Sales tax is visible to consumers; VAT is often embedded in prices
- Global Usage: Sales tax is primarily used in the U.S.; VAT is used in over 160 countries worldwide
- Business Impact: Businesses pay VAT on inputs but get credits; sales tax is generally a final consumer burden
- Rate Structure: VAT rates tend to be more uniform within countries compared to sales tax rates
While both taxes ultimately burden consumers, VAT is generally considered more efficient for governments to administer and harder to evade, though it can be more complex for businesses.
