Sales Tax, VAT and GST Calculator

Add tax to a price, or work out the tax inside one.

Three systems in one tool: US sales tax with state and local rates, VAT for the UK and EU including reduced and zero rates, and GST for India, Australia, New Zealand and Canada. Works both ways, which matters most under VAT, where displayed prices already include the tax.

Sales tax on an invoice, without the awkward corrections

Getting the number right is the easy half. These are the four places sales tax goes wrong between the quote and the return.

Quote net, invoice with the tax shown

Quote the price before tax and show the tax as its own line on the invoice. A client who sees one combined figure will remember the larger number and argue about it later, and you will have no clean way to prove what you charged.

Work quoted$1,000.00
Sales tax at 8.25%$82.50
Invoice total$1,082.50

The invoice generator keeps tax on its own line and totals it for you.

Tax-inclusive pricing comes out of your margin

If you advertise a round number and absorb the tax, the tax is paid from your side of the line. On a 30% margin at 8.25% tax, roughly a quarter of the profit on that sale disappears.

Work backwards from the net you need with the remove-tax mode above, and price the job on that figure rather than the advertised one.

Use the rate for the delivery address

The rate that applies is usually the one where the customer takes delivery, not where you are registered. State base rates are the smaller part: city, county and district taxes routinely add two points or more on top.

Put the rate you used on the invoice, and state it the same way on the quote, so a query six months later has an answer.

The tax you collect is not your money

It is held for the state until the return is filed. Treating it as income is how businesses find themselves paying a return out of next month's work.

Keeping it as a separate line on every invoice is what makes the return a copying exercise rather than a reconstruction.

The rate is one line on a document that has to be right

Sales tax turns up twice on every job: once on the quote, where it sets expectations, and once on the invoice, where it becomes money you owe the state. Both documents are free here as well.

How do you calculate sales tax, VAT and GST?

Add tax: Tax amount equals price before tax times tax rate divided by 100. Total equals price plus tax. Example: 100 dollars price, 6.25 percent Texas base rate: Tax equals 100 times 6.25 divided by 100 equals 6.25 dollars, Total equals 106.25 dollars. Remove tax: If you have total including tax, price before tax equals total divided by 1 plus rate. Example: 106.25 dollars total with 6.25 percent tax: Price before equals 106.25 divided by 1.0625 equals 100 dollars, Tax equals 6.25 dollars.

What is sales tax?

Sales tax is a fee added at checkout when you buy goods or services. The seller collects it from you and sends it to the state or local tax office. The rate depends on where you are and what you are buying. This money pays for schools, roads, police, fire and other public services. For anyone who sells, getting the tax right matters, because collecting too little or too much can cause penalties or lost sales.

Who collects

Seller collects at point of sale, then remits to tax authority monthly, quarterly or yearly depending on volume.

Where it goes

State and local governments use it as a major revenue source, almost a quarter of their combined collections.

Why rates differ

Each state sets its own base, and cities and counties can add more. So two stores a few miles apart can have different totals.

Why is there no federal sales tax in the US?

Unlike many other countries, the US does not have a national sales tax. Each state decides if it wants one and how high. Out of 50 states plus DC, five have no statewide sales tax at all: Alaska, Delaware, Montana, New Hampshire and Oregon. Alaska does allow some cities to charge their own local tax though. For all other states, the rate changes not just by state but by county and city, so compliance gets tricky fast. Rates can be 0% to over 10% combined depending on location and what you sell. For example Texas does not tax prescription medicines or food seeds, while some states add extra tax on alcohol for immediate consumption.

A short history of sales tax in the US

Sales tax in the US is newer than income tax. Mississippi started the first state sales tax in 1933, during the Great Depression, to raise money when property taxes fell. Other states followed quickly. By the 1960s most states had a sales tax. Unlike Europe which uses VAT, the US stayed with a state and local system. Over time cities and counties added their own layers, creating thousands of tax areas. Then online shopping came, and the 2018 South Dakota v. Wayfair decision let states require sellers to collect tax even without a store in that state, if sales pass a threshold. That is why a small business today can need to track sales in many states.

Can you deduct sales tax? Business against personal

For businesses

Tax you collect from customers is not your money, you hold it for the government and send it in. You do not deduct that. What you can often deduct is sales tax you pay on things you buy for work, like supplies or tools, as part of business expenses, depending on state rules. Keep receipts of tax paid on purchases and check with your accountant.

For individuals

When you file federal tax, you choose to deduct either state and local income tax or state and local sales tax, not both, called SALT deduction capped at 10,000 dollars. If you live in a state with no income tax, sales tax deduction can help more. IRS lets you use actual receipts or estimate using tables based on income and family size. For big items like a car, you can add actual tax paid.

Local rules, exemptions and how they affect pricing

Local complexity

A city can charge extra on top of state. So total in one town can be 7%, a few miles away 10% because of extra county or district tax. You need exact address to get it right. For shops that ship, this means checking each customer address.

Exemptions

Many states do not tax groceries, prescription drugs, or medical devices to lower burden. Some services like consulting may not be taxable. Alcohol, tobacco and luxury items often have extra tax. Texas exempts food seeds, Vermont adds 10% extra on alcohol for immediate use. Not every sale is taxed the same.

Pricing and margin

If you show price without saying tax is extra, customers may think you are expensive. If you include tax in price, your margin shrinks. Our calculator shows tax breakdown clearly so you can keep margin healthy and customers know what they pay. On our invoice generator you can show tax line separately.

Online sales and economic nexus after Wayfair

Compliance is hard

There are thousands of tax areas in the US. Each has its own rate and filing schedule. You must collect right amount, file reports on time and send money to each place, sometimes monthly or quarterly. Rates change often at state and local level. Tracking by hand takes time and causes errors.

Wayfair and economic nexus

Before 2018 you needed a physical store to collect tax in a state. After South Dakota v. Wayfair 2018, states can require collection based on sales volume, even without physical presence. Most states use 100,000 dollars sales threshold. So if you sell online to many states, you may need to collect in those states. Utah removed 200 transaction rule in 2025 and now uses 100k only. Alaska removed 200 transaction rule too.

VAT vs sales tax vs GST: what is the difference?

Outside the US most countries use VAT or GST, not sales tax. They work differently.

VAT how it works

Manufacturer pays VAT on raw materials, wholesaler pays VAT but deducts VAT already paid, retailer charges VAT to final customer and deducts previous VAT. End customer pays full VAT, businesses act as collectors.

GST how it works

Similar to VAT, broad tax on most goods and services. Collected at each stage, businesses claim input credit. Final consumer bears tax. Designed as single unified tax replacing many indirect taxes.

What we do

Our invoice generator supports tax lines for sales tax, VAT and GST. You can set rate, show breakdown and add your VAT ID or GSTIN. Useful if you sell to clients in EU, UK, Canada, Australia, India.

Sales tax, VAT and GST questions, answered

Quick answers to questions we get a lot about sales tax. Use the calculator above to check your own numbers.

How to calculate sales tax?

Multiply the price by the rate as a decimal, then add it on. At 8.25%, a $100 item carries $8.25 of tax and costs $108.25. The calculator above does it both ways, because working backwards out of a total is the version people get wrong.

How to remove sales tax from total?

Divide by one plus the rate, do not subtract the percentage. A $108.25 total at 8.25% came from $100, not from $99.28. Subtracting 8.25% of the total is the most common sales tax mistake on an invoice.

What is California sales tax?

The statewide rate is 7.25%, and local district taxes push the combined rate well above 9% in many cities. Always use the rate for the address where the sale is taxed rather than the state headline figure.

Which states have no sales tax?

Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax, though Alaska allows local sales taxes that can still apply. The other 45 states and DC all levy one.

Is shipping taxable?

It depends on the state and often on how you invoice it. Several states tax delivery when it is part of a taxable sale, and some exempt it if it is stated separately and the customer could have collected the goods. Itemise shipping so the treatment is at least visible.

What is the difference between base rate and combined rate?

The base rate is what the state charges. The combined rate adds the average city, county and district taxes on top. Texas is 6.25% base and about 8.19% combined, and the difference is money you either collect or absorb.

Methodology, and what runs in your browser

Every figure here is worked out in your browser, with no storage and no API call. Adding tax multiplies the net price by the rate. Removing it divides the gross by one plus the rate, which is the step people get wrong when they subtract the percentage instead. State base rates are 2026 figures from public sources; local rates sit on top and vary by address.

Disclaimer: Base rates shown. Many cities and counties add local tax on top. Check your exact address rate if this matters. Estimates for informational purposes only.

What is sales tax and why no federal rate

Sales tax is charged at the point of sale and handed on to the state. The seller collects it and sends to state or local tax office. Rate changes by location and product. US has no national sales tax. Each state decides if it charges. Five states have no statewide tax: Alaska, Delaware, Montana, New Hampshire, Oregon. Alaska allows some cities to charge local. All other states set own rate, cities and counties can add more, totals vary street by street. Rates 0% to over 10% combined. Exemptions vary by state and by category, and some states add extra duties on top for particular goods.

Local complexity, exemptions and pricing impact

Local complexity

Many cities counties and special districts add own tax, so total rate can vary a lot even between nearby towns. Example product sold in one city might be 7% combined, few miles away over 10% due to extra local. You need exact address to apply correct rate. For small businesses freelancers blue collar pros, manual tracking can cause undercharging or overcharging.

Exemptions and special cases

Many states exclude necessities like groceries prescription medications and medical devices to reduce burden. Some services like professional consulting or certain labor may not be taxable. Alcohol tobacco luxury goods often have higher or extra taxes. Vermont adds extra 10% on alcohol consumed immediately. Not every sale taxed same.

Impact on pricing and margin

If you do not say tax is extra, customers may think prices higher than competitors who include tax. If you absorb tax costs on items like discounts that reduce taxable amount, margin can shrink. Seeing the split matters most on tax-inclusive pricing, where the tax quietly comes out of the margin rather than off the top.

Frequently asked questions

Moved to very end, old content kept plus new non-repeating questions added. All rewritten in own words, only as reference.

Who should collect sales tax?

Any business with nexus in a state: a physical presence, or enough sales into it to cross the economic threshold. Collection is your obligation, not the customer’s, which is why getting the rate right on the invoice matters.

Do I need to collect sales tax when selling online?

Often yes. Since the Wayfair decision, states can require collection based on sales volume alone, with thresholds commonly around $100,000 or 200 transactions a year. Check each state you sell into rather than assuming your home rules apply.

How often should I file sales tax returns?

The state tells you, and it is usually monthly, quarterly or annually depending on how much you collect. Filing frequency can change as you grow, so check the notices rather than assuming last year’s schedule still applies.

What happens if you forget to collect sales tax?

The liability is generally still yours, so the tax comes out of your margin along with any penalty and interest. That is the practical argument for putting the correct rate on the invoice at the time rather than reconciling later.

How do I calculate VAT?

Multiply the net price by the rate to add it, or divide the gross by one plus the rate to take it out. At 20%, a net 100 becomes 120, and a gross 120 came from 100. Under VAT the second direction is the common one, because displayed consumer prices already include the tax.

How do I remove VAT from a total?

Divide by 1.20 at the standard UK rate, not by subtracting 20%. A gross 120 came from 100, while subtracting 20% gives 96, which is wrong by four pounds on every hundred.

What are the UK and EU VAT rates?

The UK standard rate is 20%, with 5% reduced and 0% on some essentials. EU standard rates run from around 17% to 27%, and most countries also operate one or two reduced rates. Pick the country above and the calculator loads its standard rate with its reduced rates beside it.

What is the difference between VAT and sales tax?

Sales tax is charged once, at the final sale, and businesses buying for resale are exempt. VAT is charged at every stage, with each business reclaiming what it paid, so only the final consumer carries the whole amount. The arithmetic is the same; the paperwork is not.

How is GST calculated in India?

By slab rather than by a single national rate: 5, 12, 18 and 28 percent depending on the category of goods or services. Pick the slab above and the split appears the same way as any other rate.

What is the GST rate in Australia and New Zealand?

Australia charges 10% on most goods and services, with some supplies GST free. New Zealand charges 15%. Both are single national rates, which makes them simpler than either US sales tax or EU VAT.

How does GST work in Canada?

Federal GST is 5%, and provinces either add a provincial tax on top or combine both into HST. Alberta charges GST alone; Ontario charges 13% HST; Quebec adds QST to the federal GST. Choose the province above and the combined rate loads.

Do I charge VAT or GST to overseas customers?

Often not, or at zero rate, but the rules depend on whether the customer is a business, where they are, and what you are selling. Digital services in particular have their own rules. Check your own jurisdiction rather than assuming the domestic rate applies.

How do I add sales tax to a price?

Multiply the price by the rate as a decimal and add it on. At 8.25%, $100 becomes $108.25. Charge the rate that applies where the sale is taxed, not where your business is registered.

How do I work out the tax inside a price?

Divide the total by one plus the rate. A $108.25 total at 8.25% came from $100. Subtracting 8.25% of the total gives $99.28, which is wrong, and it is the mistake that shows up most often on invoices.

Should my prices include sales tax?

In the US, prices are usually shown before tax and the tax is added at checkout. If you do quote tax-inclusive prices, the tax comes out of your margin rather than off the top, so work backwards from the net you need.

What sales tax rate should I put on an invoice?

The combined rate for the address where the sale is taxed: state, county, city and any district on top. The state figure alone is usually too low, often by more than two points.

Do I charge sales tax to out-of-state customers?

Only where you have nexus, which since the Wayfair decision can be created by sales volume alone. Thresholds are commonly around $100,000 or 200 transactions a year, and they are set per state.

Is sales tax charged on services?

It depends on the state and the service. Some states tax most services, others almost none, and many sit in between with a specific list. Check your own state rather than assuming labour is exempt.

What is use tax?

The counterpart to sales tax: if you buy something taxable without paying sales tax, you generally owe use tax at the same rate. It catches out-of-state purchases and is where small businesses most often find an unexpected bill.

Do I charge sales tax on a deposit?

Usually when the deposit is part of a taxable sale, though timing rules vary by state. The practical approach is to show the tax treatment on the deposit invoice so the final invoice reconciles cleanly.

How do I record sales tax collected?

As money held for the state, not as income. Keeping it visible as its own line on every invoice is what makes the return straightforward and stops the balance being spent.

Is the sales tax calculator free and private?

Yes. No signup and nothing uploaded: every figure is worked out in your browser and gone when you close the tab.

Should sales tax be a separate line on an invoice?

Yes. It shows the client what they are actually paying you for the work, it makes your return a copying exercise rather than a reconstruction, and it settles any later question about which rate was applied.

What happens if I quote a price and forget the tax?

Adding it afterwards is an awkward conversation, and many clients will treat the quote as final. Quote net and say plainly that tax will be added, or quote the tax-inclusive figure knowing it comes out of your margin.

Do I charge sales tax on the deposit or the final invoice?

Usually on both, in proportion, though the timing rules vary by state. Whichever you do, show the treatment on the deposit invoice so the final one reconciles without explanation.

How do I show sales tax on a quote?

As a separate line with the rate stated, exactly as it will appear on the invoice. A quote that matches the invoice line for line is the one that gets paid without a query.
