Have a Tax Question? Ask a Tax Expert
You can complete Form 4506 which you can access here http://goo.gl/c73ZYO. However, the instructions state it could take as long as 75 days to complete the request. It would be faster to get a return transcript which you can request online here http://goo.gl/DQC3VK.
Did you use a tax preparer or online tax form preparation service. Either of those services may have backup copies of your return for that year and would likely be the fastest way to get a copy of your return.
I hope this answers your question. Please let me know if I can clarify anything or answer any additional questions. Thanks, Jonathan
