H&R Block has decided not to make a Mac-compatible version of TaxCut for 2005. I've been successfully using Intuit's TurboTax (previously MacinTax) for years, but I'm still disappointed that another manufacturer has decided to abandon the Mac platform. Perhaps it wouldn't matter so much if the web-based tax software tools worked as advertised. The only year I attempted to use a web-based tax software tool was 2003 and quickly abandoned it in favor of the more robust and easier-to-use application software.
Their emailed response to my inquiry about a Mac version for 2005 was:
