Congrats!
I used to be afraid of all things taxes, but it gets easier with age. I remember being scared that I might get audited in my 20s when my taxes were ridiculously simple. It all seemed so intimidating, so I went to an accountant and SHE made a mistake that I corrected before mailing in my return. After that, I decided to do them myself. Each year they got slightly more complicated, but also easier because I knew what to do from the previous year.
Then one day I received a notice that I owed the IRS $1600 more than I had sent in. After having a little panick attack, I did a little digging and realized I HAD made a mistake...but that it was in MY favor. I wrote a response, amended my return, and they sent me a check for $2200+interest. That was the day I officially got over my fear of doing my own taxes.
At some point I will hand it over to an accountant because I'm not going to trust an older version of me to get it right and be able to defend it if I'm audited.
