TaxACT® guarantees the accuracy of its calculations in the Free Edition, Express, Deluxe and 1040 State Editions of TaxACT only. If the IRS assesses a penalty due to a calculation error generated by TaxACT Free Edition, Express, Deluxe or 1040 State on the Consumer's tax form, TaxACT will reimburse Consumer the amount of the penalty and interest attributed to the calculation error. This remedy is limited to Consumer's personal return and does not apply if Consumer uses TaxACT to prepare returns for persons or entities other than Consumer. This guarantee and warranty does not apply if Consumer overrides amounts within any tax return.

The ultimate responsibility for any tax returns prepared using TaxACT software remains with Consumer. This Guarantee does not apply to, and TaxACT has no responsibility or liability for, Consumer's failure to enter all required information accurately, Consumer's willful or fraudulent omission or inclusion of information on a tax return, Consumer's wrongful classification or description of information on a tax return, or Consumer's failure to file a timely tax return.

If Consumer believes he or she is entitled to the reimbursement described herein, Consumer must provide written notice to TaxACT, Inc., within 30 days of the IRS/State Agency imposing a penalty at 1425 60th Street NE, Cedar Rapids, IA 52402. The Consumer must include a paper copy and a data file copy of the TaxACT return, a copy of the penalty notification from the IRS and any other pertinent data that may be requested in order to determine if the penalty was indeed due to a calculation error in TaxACT Free Edition, Express, Deluxe or 1040 State.
