Yes, the taxes. Sorry for my English.
That's what I thought!
Different Countries, different laws. Usually your winnings will be small enough to where a poker room is not bound by law to report. Larger winnings however might be reported, or at the least are subject to be released to a government entity (The US's IRS for example).
Skirting your tax laws is not advisable. Anybody who states otherwise, take with a grain of salt. Don't fall under the impression that you will get away with it. My advise is to take it like a citizen and pay your taxes. You may gain in the short-term, but the long-term river card will eventually get you audited or worse.
I have never played on 888 but I think it is good at least for Canadians--the best site for one country might not be so good for another country--you would have to ask other people from Brazil
Umm. Yes you did ask how to avoid taxes.
What I think you meant to ask is what method of withdrawal has the lowest fees associated with it.
All types of money transfers don't have any taxes taken out of them that I know of. It is zero taxes for checks, bank transfer, bitcoin, etc.
The fees for withdrawal vary. Checks have a steep fee tacked on, while bitcoin fee is free. The fees differ from poker room to poker room. In addition to those, there might be fees added on the receiving end such as your bank, wallet, mining, etc. And those vary. too.
The most convenient method would be direct transfer into your bank account. Fees could be moderate, less than 2% tho. Not all poker rooms can direct deposit into your bank account though, depends on your Countries restrictions.
