TaxCalc 2011 Personal 12

The TaxCalc Personal range of products has been thoughtfully designed to bridge the gap between you the taxpayer and the HMRC forms. Not only does TaxCalc make completing your self assessment tax return child's play, it puts you firmly in control of your tax affairs, calculating your tax liability or rebate as you make your way through the program. TaxCalc's unique method of entering your information called SimpleStep®, guides you through the data that you will need to input to complete the self-assessment tax return. Alternatively, you can enter your data directly onto HMRC 'identical forms'.

Once complete, you can then either file online by the deadline date 31st January 2012, or print a paper copy of your HMRC form and post it for arrival no later than 31st October 2011.

Other Operating Systems:

We have many customers happily operating TaxCalc under one of the handful of solutions which allow Windows to be emulated on Mac. Further details can be found here.

Once you have a Windows desktop up and running on your Mac, TaxCalc will work exactly as it does on a PC and we will provide our usual level of support.

It is very much our intention to make all our products available to run natively on Mac and your feedback would help us prioritise this project.

Works for me
