IR35 hasn't really affected that path, you can find contracts that are outside of the legislation and as long as your working practices are also outside you're fine, there are also insurances now for these things.
There is also nothing -- literally, nothing -- to prevent you from finding a remote work contract with a US company, and billing them at a rate appropriate for the US market. From your point of view, there is no VAT chargeable on B2B services supplied to a customer located outside the EU, and you can get paid easily using a Wise account. From the client's point of view, give them a W2-BEN-E and they can effectively consider you as 1066 status.
Do you mean 1099 status?
Yes -- thank you.
A lot of companies don’t hire contractors under their own LTD anymore they only take those that come through an umbrella company that pays them under PAYE.
The people taking these roles arguably aren’t contractors anyway. The market in the uk for contracts outside the legislation is healthy.
Is there a difference in pay that you’d get if you billed an umbrella company? Or are you liable to pay more tax?
You are basically getting payed as PAYE that way so yes.
