📌 Key Takeaway: Most major tax software offers an accuracy guarantee covering IRS penalties and interest caused by a calculation error in the software itself — but these guarantees generally don't cover errors caused by information you entered incorrectly.
What's Typically Covered
If the software's own calculation is wrong and it results in an IRS penalty or interest charge, most providers will reimburse that penalty and interest amount.
What's Usually Not Covered
- Errors caused by information you entered incorrectly or omitted.
- Your original tax liability itself (the guarantee covers penalties/interest, not the tax owed).
- Audit outcomes unrelated to a software calculation error.
Audit Support Add-Ons
Several providers sell a separate audit defense or audit support add-on that provides professional representation if you're audited — distinct from the standard accuracy guarantee and worth reading the terms of before assuming you're covered.
