I'm incorporated in Isle of Man. Stripe isn't available, but others are. 0% tax, it absolutely looks like you're incorporated in the UK for anyone who doesn't know what to look for (UK phone number, VAT number, UK-looking address, UK sort-code, etc). Banking is a PITA, but I've been making it work with Wise. You'll probably shell out at least $5k a year in accountancy and service fees. Also it's small enough that your accountant can ring up his buddy Fred who's the Tax Minister this year to get clarity on any points of law.
