Scrambling last minute to figure out what to do but google searches didn’t help.
Here’s my scenario:
I worked in 2 states in 2017. NY & PA.
I submitted my return for federal and NY only thinking I could just submit the PA on its own using H&R Block. However, the software won’t allow me to submit the PA since it appears it has to be tied to the federal.
What is my best option? Amend my federal and ask for extension?
You will be totally fine if you mail tomorrow. I promise.
They do not start to check postmarks in Harrisburg for at least a week. There are thousands of returns incoming. USPS transit time differences easily can exceed several days. It’s not as if they check every incoming piece of mail; that simply is not practical.
OTOH, to protect yourself mail in your return ASAP. But if you do it as soon as tomorrow you can totally relax. If you instead wait until the weekend or next week to mail it in you cannot be quite as relaxed.
You have 3 years from the return due date, including extensions, to claim a refund. For 2014, if you didn’t get an extension, it’s too late now since that deadline would be 3 years after Apr 15th, 2015.
Also, remember the sooner you file, the sooner the 3-6 year clock starts on the IRS contesting your return, so generally it’s good to do things sooner rather than later once you have all the information you need.
