H&R Block, which has served more tax clients than any other single company through is offices in the U.S., U.K., Canada, and Australia, has announce an exclusive agreement with Inisoft to provide online personal tax preparation services throughout Canada. The service will provide total compatibility with Canadian Customs and the Revenue Agency so that all Canadians, including those abroad, who have Internet access will be able to use the software to prepare income tax returns.

Expecting to dominate the Canadian marketplace for online tax software, H&R Block International’s President Jeff Yabuki said, “Our partnership with Inisoft allows Block to be the complete tax preparation solution for all Canadians, whether they file their own return or get help from one of our 8,000 tax advisors across Canada.

The Block/Inisoft solution is not the only way to get taxes done online in Canada. QuickTax by Quicken (the folks that provide TurboTax in the States) will provide competition for Block, and a quick search of the Internet unearthed many other online tax filing solutions.
