I propose that the government standardises the taxation procedures and the level of tax for all gambling.
The current taxation of gambling is regulated in different laws, depending on the type of gambling.   The tax rates vary, in some cases the tax is withheld by the organiser, in others the winnings have to be declared by the winner, etc. I propose that all gambling should be taxed uniformly under the provisions of the Act on the taxation of winnings from traditional games of chance. The tax on winnings would be paid at the rate of 10% of the tax base.  The tax on winnings would be calculated, withheld and paid by the gambling operator. As under the Act, the withholding tax would be considered as a definitive tax and would no longer be subject to additional taxation.
I am also proposing a change in the legislation because the gambling tax is too high. Many countries in Europe do not have such a tax, or it is much lower than it is now under our legislation. The winnings are the net amount or the object won and are not taxed.  The most important reason for the change, however, is that our legislation favours traditional gambling. For these games, the taxation procedure is simple and the tax rate is the lowest (15%). Everything is arranged and done by the organiser of these games of chance. This could also be the case for other gambling.
Best of all, there would be no tax on winnings at all. The shortfall in funds would be covered by the gambling operators through higher concession fees and taxes.
