For tax year 2012 I filed for extension and paid an estimated amount. I then forgot to file for real by the deadline of Oct 15 2013. Still haven't filed. My reason is personal issues if that can help for penalty abatement.

For tax year 2013 I filed using TurboTax and e-filed but the e-file didn't go thru because of an error. I never saw the reject e-file email from TurboTax (until recently) and so I never filed and the payment that went along with that e-file didn't go thru either.

I have not been contacted about either year by the IRS. I did file for 2014 on time. I lived in Texas for tax years 2012 and 13 so no state income tax.

What is my best step forward at this point? Should I hire a tax professional or just call the IRS and find out the penalties are and re-file for both years and pay up?

Can a tax professional help me save money in my case?
