At what point to get serious with accounting for business

I started an online site and start up costs were very little. It's been 3 months and I have made a bit of profit, but nothing too significant. At what point should I actually consider consulting with an accountant about possible options to minimize the tax I need to pay back for profits. Currently, any money made is just deposited into my personal account since it's just a few bucks here and there. I don't know if it will be worth it to get a business tin, LLC, business checking account etc for such a small venture (more like a hobby). Looking for any advice so if one day I see an accountant, I'll have some specific questions to ask



Thanks
