Our enhanced Tax Alert! version may SAVE YOU FROM PENALTIES. How? 2012 Tax Reference includes (i) access to receive our regular TAX ALERTS (when you sign up, you will receive regular short email alerts of upcoming filing deadlines. Forgetting to file a quarterly 1040ES on time may cost much more than the price of a cup of coffee); (ii) incorporates the recent legislative changes to the tax code AND also State tax information. The Tax reference is information at your fingertips including corporate tax rates, retirement contribution limits, depreciation, business deductions, personal tax rates, itemized deductions, estate and gift taxes and lots of other useful financial data... for when you need it in a pinch. The 2011 Tax Reference was very well received - 2012 Tax Reference is a MUST HAVE.
