What are the new rules for working as a freelancer?

It depends a lot on which country you're in, because there are no global rules for freelancers. In many places in Latin America they're asking for more formalization, like registering as an independent worker or as a monotax payer, and some countries are starting to get involved in the taxes you have to pay on online income. Best thing is to check with an accountant or on your country's tax website specifically, because each place has its own way of doing things and they change pretty often.

What's changed the most is that many freelance platforms now require identity verification and tax information from the first payment, so if you work through those channels you can't dodge those requirements anymore. Besides the formalization they mention, it's worth checking if your country has any special tax regime for self-employed or independent workers, because some countries now offer more accessible options than before so you don't end up paying like you're a big company.
