Why is custom software necessary at all? In the Philippines, if you are registered with eFPS, and have an account in one of the accredited banks, nothing is needed except a web browser.
Makes sense. I used to prepare taxes so I appreciate the value of human insight there. I also have contempt for the industry because so few practitioners will teach easy cases to fish, or refrain from optimizing a return when the cost of prep exceeds the amount saved. (Not saying your situation is easy; it’s not.) Plus I do think it’s time the IRS stepped up automation for simple returns.
