I have started a side hustle service business in the US (I am based in the UK). I set it up on a whim to test the concept, so only initially set up a Wise business account so I could receive USD, otherwise have not set up an LLC or anything else in the US yet, nor have I set anything up in the UK (i.e. I am a sole trader for the side hustle). I just invoiced two clients and received $45k in my Wise business account. Through my day job I am already a higher/additional rate taxpayer on PAYE (varies year to year but will be £100-140k), so would essentially lose half of this income to tax when Wise report it to HMRC at the end of the year. Can I retrospectively open an LLC in the US and have this income count under that, and if so are there any benefits to doing that and keeping the money in there for now until I quit my day job in the future and do this full time (at which point I could draw profit more efficiently)?
