WinTax is a free Canadian payroll tax calculator. WinTax provides users with an easy way to calculate taxes on regular salary, bonus, retroactive pay and commission. Calculations include CPP, EI, Federal tax and Provincial tax (including Quebec).We believe every HR professional would benefit from using software to assist them in their job. But many can not automate due to the high cost of most software in the market place. That is why HR Club is introducing a new way of encouraging the use of software by charging an affordable Annual Fee for each product instead of a high initial purchase price. The Annual Fee allows the use of the software for a full year with e-mail support, access to the latest version of the software and membership to HR Club.
