The enclosed check was cashed within a week. That summer I got a letter my tax return was overdue so I sent in a copy.
A month ago I got another similar letter. Sent in another copy. When I check my tax status online, they still have not been processed even though it shows my payment made.
The IRS is incompetent. And excessive if not unconstitutional.
One time I had some tax issue that weren’t being addressed in my favor. Then they sent me a handwritten note, on note paper, telling me I needed to pay them. I ignored them after that, and 10 years later my dispute was settled in my favor. If they were sending handwritten notes 15 years ago, it hasn’t gotten better since then.
