TAC - The Tax Apportionment Calculator Description:

The Tax Apportionment Calculator, TAC version 4.0, provides a fast and easy way to calculate Goods & Services Tax (GST), or Income Tax or Sales Tax or Value Added Tax (VAT) and apportion tax and expenses or income across different cost centres. TAC presents the result of a computation in a format that is easy to read and check visually.

TAC system settings cover two tax years for five different countries or user-defined names. This powerful feature makes it easier to set the default tax types and rates for different tax cases under National (Federal) and or State taxes or new tax rates planned for in a government's annual budget

TAC, which also covers basic mathematical calculations, was designed for accounting staff, auditors, business people, financial planners, investigators, lawyers and other computer users who wish to save time and have all the tax figures calculated quickly.
