- -Most everything in boxing is smoke and mirrors.

The only thing real are the fighters, but sometimes even they succumb to the lure of smoke and mirrors.

That would be impossible to enforce. Then there's the tax treaty where if you pay income tax in one country you don't have to in another.

Yes, you're right. It's impossible to enforce. That's why fighters file misleading numbers. You're also right that there are tax treaties and Joshua will get tax credit in the UK for taxes paid in the US for US events.

What you're wrong about is thinking that the US won't collect taxes from a US event simply because the company paying the purse isn't a US company. That's just not how it works. Best of luck to you, I hope you have a wonderful day, you just happen to be wrong on this facet of the issue.
