About us


Welcome to CS17 Tax Calculator, part of the CS17 Tools collection of practical and easy-to-use online tools. CS17 Tax Calculator was created to make everyday tax calculations quicker and easier. Whether you need to add tax to a price, remove tax from a tax-inclusive amount or simply calculate the tax component, the calculator is designed to provide a clear result without unnecessary complexity.

Tax Calculations Made Simple

Tax systems vary considerably around the world. Depending on the country, taxes may be known as GST, VAT, sales tax, consumption tax, HST, PST, QST or other names. Some countries have a single national rate, while others have multiple rates or taxes that vary by state, province or local area. CS17 Tax Calculator brings many of these common calculations together in one simple online tool. Select your country, choose the appropriate tax rate, enter your amount and let the calculator do the calculation.

More Than One Tax Rate

Not every purchase within a country is taxed at the same rate. Some countries have standard, reduced and zero-rated categories. The United States can have different state and local sales-tax rates, while Canada uses combinations of GST, HST and provincial taxes depending on the province or territory. For this reason, CS17 Tax Calculator allows users to select from available tax rates and, where appropriate, enter a custom or local rate. This provides greater flexibility while keeping the calculator simple to use.

Keeping Tax Rates Up to Date

Tax rates can change. CS17 Tax Calculator has been designed with a tax-rate update system that periodically checks the configured government or reference sources used by the calculator. We take a cautious approach to automatic updates. Government tax websites can contain current rates, historical rates, reduced rates and other percentages on the same page. Rather than automatically replacing a tax rate with an unverified number, the calculator is designed to retain validated information until a new rate can be reliably identified. Users should still confirm the applicable tax rate with the relevant tax authority when making important financial or business decisions.

Designed for Everyday Use

Our aim is to make CS17 Tax Calculator useful for a wide range of people, including individuals, small businesses, tradespeople, retailers, students and anyone who needs to perform a quick tax calculation. The website has been designed to work on desktop computers, laptops, tablets and mobile phones. There is no software to install and no account required. Simply open the calculator and start calculating.

General Calculation Tool

CS17 Tax Calculator is designed as a general calculation tool. It calculates tax based on the country, region and rate selected by the user. It does not determine whether a particular product, service or transaction is taxable. Tax laws and rules can vary depending on the type of transaction, location, goods or services involved and other circumstances. For important tax, accounting, financial or business decisions, calculations and applicable tax treatment should be independently confirmed with the relevant tax authority, accountant or another appropriately qualified professional.
