Retail Sales Tax, VAT and GST Explained for Shop Owners
By Quantum Solutions · 3 min read
Short answer: sales tax is collected once at the final sale, while VAT and GST are collected at every stage and passed along with credits for tax already paid. As a shop you collect tax from customers, report it, and pay it over. Rates and rules differ by country and change over time, so always confirm with your tax authority.
This article is general information, not tax advice.
Key takeaways
- Know whether your shelf price includes tax or adds it at the till.
- Charge the right rate per product, because rates can differ within one shop.
- Keep a record of taxable sales and tax collected for each rate. That is what most returns ask for.
- Rates and invoice rules change. Check current ones before you rely on this page.
Sales tax vs VAT vs GST
Sales tax (the United States) is added when the customer buys. The shop collects it and pays it to the state or local authority. Rates and rules vary by state and sometimes by city.
VAT and GST (most of the rest of the world) are charged at each step. A supplier charges you VAT on goods you buy, you charge your customers VAT on what you sell, and you pay the difference to the authority. Prices shown to consumers usually include the tax.
Typical standard rates by market
These are widely published standard rates. Rates change, reduced rates and exemptions apply to some goods, and some places have extra local taxes. Confirm the current rate where you trade.
| Market | Tax | Typical standard rate |
|---|---|---|
| India | GST | Several rates set by the GST Council. Check the current schedule |
| United Arab Emirates | VAT | 5% |
| Saudi Arabia | VAT | 15% |
| Thailand | VAT | 7% |
| Japan | Consumption tax | 10% standard, 8% reduced rate on some food and drink |
| Australia | GST | 10% |
| United Kingdom | VAT | 20% |
| European Union | VAT | Varies by country, roughly 17% to 27% |
| United States | State and local sales tax | No federal sales tax. Rates vary by state and locality |
Tax-inclusive and tax-exclusive prices
If the shelf price is tax-exclusive, tax is added on top. A $10.00 item at 10% tax costs $11.00 at the till.
If the shelf price is tax-inclusive, the tax is already inside it. A $10.00 item at 10% tax contains $0.91 of tax and $9.09 of revenue (10 / 1.10 = 9.09). When you work out your profit, use the $9.09, not the $10.00. See gross margin vs markup.
Different rates in one shop
A grocery might sell some items at a standard rate, some at a reduced rate and some at zero. Set the tax rate on each product rather than one rate for the whole shop. Your receipts then show the right tax per line and your tax summary adds up per rate.
Receipts and invoice rules
Some countries have specific invoice requirements. Japan, for example, has a qualified invoice system for tax registrants, and other markets require tax numbers on receipts. Check what your local authority expects, then make sure your receipt carries your business name, address, tax ID where required, date, items, tax and total.
How DukaanAI helps
Each store in DukaanAI has its own currency, time zone and tax scheme (sales tax, VAT, GST or none). You set a tax rate on every product, choose whether prices include tax, show your tax ID on receipts, and the sales tax summary report lists taxable sales and tax collected by rate for any date range, ready to export as CSV or print.
Frequently asked questions
What is the difference between sales tax and VAT?
Sales tax is charged once, at the final sale to the customer. VAT and GST are charged at every step of the supply chain, and each business can reclaim the tax it paid on its purchases, so the tax ends up falling on the final customer.
Should my shelf prices include tax?
It depends on local rules and habits. Many countries with VAT or GST show tax-inclusive prices to consumers, while the US usually adds sales tax at the till. Use whichever your market expects and make your receipts clear.
Can one shop sell items with different tax rates?
Yes. Many places apply a reduced or zero rate to some goods, such as basic food. Set the rate on each product so the receipt and your tax report are correct.
