Is Turbo Tax accountable for providing erroneous tax due amount? I was hit with a $103 past due amount even though I thought I paid in full. What gives?

I pay Turbo Tax under the assumption it will provide an accurate tax bill due. What if they err?

[Mike9241]

if the underpayment was due to a Turbotax calculation error you can file a claim. if it's an error on your part any penalties and interest are your responsibility. we don't know in your case which is the case.

Also, check a copy of your actual tax return to see what the final bill was supposed to be. (line 37 of the form 1040)

Then check to see if you paid that amount on either your Credit card, or bank account statements.

Make sure you are NOT using the TurboTax filing charges as part of your IRS payment. 

The IRS payment is entirely separate from the TTX software charges.

How much was your tax due?  It may be for the tax penalty for owing too much.  Turbo Tax can not  accurately figure the estimated tax penalty on 1040 line 38.  Was there a penalty on your 1040 line 38?

The penalty is just an estimate so it is possible for the IRS to recalculate it and it is common and normal for the IRS to send you a refund or a bill for more. If line 38 is blank you might have checked a box to let the IRS figure it for you. Nothing you can do about it now. 

If you do not pay in enough tax from withholding and estimates, you may have to pay a penalty for underpayment of estimated tax. The penalty is an Estimated amount. Even if you are getting a refund you can still owe a penalty for not paying in evenly during the year. Generally, most taxpayers will avoid this penalty if they owe less than $1,000 in tax after subtracting their withholdings and credits, or if they paid at least 90% of the tax for the current year, or 100% of the tax shown on the return for the prior year, whichever is smaller.
