Tax Program Problem: TaxAct
If you use TaxAct be aware there is at least one glitch.
If you bought either a taxable bond OR a tax exempt bond and paid accrued interest the schedule B will show the correct taxable income. If you bought BOTH, however, the schedule B will understate the taxable income and therefore the tax.
I showed em this glitch last year and they said they'd fix it but they haven't. I emailed em today. Maybe they will patch it--hope so--but they've had a year .....
