Oof, that’s not a lot of training. But most people who start doing taxes don’t have a lot. It is bullshit that your supervisor isn’t there. You’re probably not going to prison for mistakes. Your employer will get fined, and you might be fined. You could go to prison for willful negligence. If you don’t know the answer to a question or a topic, then look it up. The Pub 17 should tell you 90.0% of what you need to know. Tell the person checking your work, and if in doubt set it aside for the supervisor to check later.
All new timers have this feeling and it goes in 4 stages:
1.) Absolutely pants filling, terror.
2.) Excitement on a few easy returns - “I could do this all day”
3.) That hard return that takes 3-5 hours to complete - “I have no idea what I’m doing”
4.) I am a tax god - "I can do anything, bring me your Schedule F’s)
Then you get through your 2nd or 3rd season and you understand that everything you know is basically just scratching the surface and there is so much more to taxes that is buried deep down, and you’ll likely either have to dig into that black hole, and hopefully come out the other side, or give up.
Most returns are fairly simple. Single filer, a couple of W-2’s maybe, a 1099-K. So you’ll be filing a schedule C, or Other income (depending on if it’s a job or a hobby).
Most of the time, it’s a business.
You will occasionally get some difficult ones. where you need to pull as much info out of the client as possible to answer the questions. The PUB 17 is filled with flow charts to help you make your decision. Sometimes the client wants to lie. Remember, you can refuse service for someone who is not being truthful.
The most likely ones I’ve seen.
Making up cash income for EITC.
Making up deductions that have no basis for business expenses.
Adding children that are not theirs to add.
Attempting to apply credits that they do not qualify for.
Usually when I see someone coming in from a paid preparer, the most common things missed:
State specific credits like the Homestead.
State specific retirements are handled poorly.
Federal/Municipal bonds being taxed incorrectly.
Occasionally I see just outright fabrication (dependents, income, deductions) these tend to happen most often with English as a second language clients. It’s done to boost the return to get a larger pay out.
