I believe I've managed to fill out my taxes myself (I've had PWC support for the last three years but now that I no longer have that paid by my company I'm trying to go it alone).
Besides the actual returns, do I need to send "proof" of income? If so, would enclosing my payslips from 2013 suffice?
After sending the documents, is there any way to verify that the IRS has received my return? This is my first year in a loooooong time that I don't owe, so I don't have the "comfort" of my payment being cashed and knowing the return has been received.
