This general-purpose Tax Calculator handles the most common tax calculation tasks: adding tax to a pre-tax amount, extracting the tax component from a tax-inclusive total, and calculating effective and marginal rates from income brackets.
Enter the amount and rate, choose whether tax is included or to be added, and get the breakdown instantly. It handles GST, VAT, sales tax, and any other percentage-based tax. The interface is simple enough that it takes about five seconds to use.
It's particularly useful for quickly checking whether a client quote should be quoted inclusive or exclusive of tax, or for verifying that an invoice amount matches the expected gross amount after applying your local rate.
Frequently Asked Questions

Yes. Any percentage-based consumption tax works the same way in the calculation. Enter your local rate and whether the price is inclusive or exclusive.
