Hey Guys! I currently have a full time job and been doing online marketing for a side income (hopefully full time 1 day I been earning more money online and was wondering if I'm better to open a LLC and pay quarterly taxes (if that how online businesses work). Should I add the extra income to my full time job at the end of the year for tax purposes? If I open a LLC, can I claim deductions like buying a computer, outsourcing, seo etc. I'm from the US. Thanks guys I just have no clue about taxes for businesses online.
