Frequently Asked Questions
What is sales tax?
Sales tax is a consumption tax added to the price of goods and services at the point of sale. In the US, rates vary by state (0-10%). The tax is typically added to the displayed price at checkout.
What is VAT and how is it different from sales tax?
VAT (Value Added Tax) is charged at every stage of production, not just at sale. Unlike US sales tax, VAT is usually included in the sticker price (tax-inclusive). Common in UK (20%), EU, and most of the world.
What is GST?
GST (Goods and Services Tax) is similar to VAT—a consumption tax on goods and services. Used in Canada (5% federal + provincial), Australia (10%), India (5-28%), and others. Our presets include common GST rates.
How do I calculate tax on a price?
Tax = Price × (Rate ÷ 100). For $100 at 8% tax: $100 × 0.08 = $8 tax. Total: $108. Our calculator handles this automatically.
How do I extract tax from a tax-inclusive price?
Use the formula: Net = Gross ÷ (1 + Rate/100). For £120 with 20% VAT: £120 ÷ 1.20 = £100 net. Tax: £20. Use our 'Remove Tax' mode to calculate this instantly.
Why do some US states have no sales tax?
Five US states have no state sales tax: Alaska, Delaware, Montana, New Hampshire, Oregon. However, Alaska allows local sales taxes. These states fund government through other means (income tax, property tax, etc.).
What is the average US sales tax?
The average combined state and local sales tax in the US is about 7.12%. However, this varies significantly—from 0% in tax-free states to over 10% in areas with high local taxes (like some parts of California or Louisiana).
Can I calculate tax on multiple items at once?
Yes! Use our 'Multiple Items' mode. Add items one by one, set which items are taxable vs. tax-exempt, and get a full breakdown with totals. Perfect for invoices and receipts.
What items are tax-exempt?
Tax exemptions vary by location. Common exemptions include groceries (some states), prescription medicines, children's clothing (UK), educational materials, and resale items. Check local rules for specifics.
What is HST in Canada?
HST (Harmonized Sales Tax) combines federal GST (5%) with provincial sales tax. Ontario uses 13% HST, Atlantic provinces 15%. Other provinces like BC charge GST + PST separately. Our presets include common Canadian rates.
