Thanks for requesting me.
Give me a moment to type my response.
The IRS allows electronic filing of tax returns for the current tax year and the two previous tax years. Prior year returns can only be filed electronically by registered tax preparers, and only when the Modernized e-File System is available.
Because you have 4 years of tax returns to file, my best advice would be to save yourself some money and mail them to the IRS and state.

I look forward to hearing from you in the future.
