Most countries have their own law about paying taxes on casino winnings. If you are not sure of percentage or limits on tax deduction on winnings, please ask your local tax authorities.
Online casinos follow strict rules regarding privacy and age restriction on gambling. To be sure that you are the one you are saying and that you are of authority, they need to collect the necessary data according to their license. If such schemes were not in place, it would be very easy for scammers to create an account in your name, or for people under the age of age to pass through the check.
The license ensures your access to the best game providers, fair games, and also a casino that takes customer safety seriously. License issuers such as the Malta Gaming Authority regularly check their registered casinos and ensure that all online casinos follow the industry standard for safety and security.
If you have had problems with gambling before, we strongly recommend staying away from online casinos. However, most players do not become addicted just because they find it fun to use such games once in a while.
