UFile TAX RATE PRO will calculate your marginal tax rate and compare all provincial tax rates for 2010 (including Quebec). This fun, easy-to-use App from UFile, the Canadian name in tax software, will help you see which province charges the most tax in 2010. It's great to use if you have a new job, got a raise, if you are moving from one province to another, or if you are a new immigrant to Canada.
It’s FREE. Install it on your iPhone today.
