No I have an accountant do those because it’s complicated. For one thing tax dates are based of the end of fiscal year you set when you form it so you have to be on top of that. For example my end fiscal year is December 31st so the LLC still has to file for this year. I’m not an expert on this side though so I would talk to an accountant.
Another thing is you want someone to go over the things you’re trying to write off so they’ll help you understand if you can.
