Been paying back taxes last year can I claim then and where do I put them .

[VolvoGirl · Accepted solution]

Sorry No.  At least not federal back taxes paid.  You can deduct any state taxes paid (for any year) or state estimates actually paid in during the year on your  federal return if you itemize deductions.   But just the tax, not any interest or penalties.  

Enter it under 

Federal Taxes (or Personal for H&B/Self Employed version)

Deductions and Credits

Then scroll way down to Estimates and Other Taxes Paid

Other Income Taxes - Click the Start or Update button

Next page scroll way down to the last section, Other Income Taxes Paid

Some states allow a deduction for Federal taxes paid (but not interest or penalties) on the State tax return.
