Frequently Asked Questions

Does TaxInterest do the interest calculations exactly like the IRS?

TaxInterest uses the same methodology as the IRS for the interest and penalty calculations.

How does the IRS make mistakes?

Calculations are based on amounts and dates. There can be wrong assumptions or incorrect inputs. Often, the IRS scans or inputs returns. There are also lots of toggles and overrides based on assumptions. The more manual touches, the more room for error. If there was an incorrect input amount or date, the interst and/or penalty calculation will be off. TaxInterest can reconcile these calculation differences.

Is there a benefit of using TaxInterest for an amended return, a non-filer, or late filer?

We all know the IRS is not known for their turn around. If you are sending in an amended return, a late return, or one for a non-filer and you pay both the tax and the interest and penalties, you are done. Otherwise, you will get another bill in a couple of months with more interest and penalties to deal with. This can get costly and create more work.

Will the TaxInterest FIN 48 Excel Add-in work with new versions of Excel and Office 365?

The add-in functions within all the latest editions of Microsoft Excel.
