This is a shame on the main:
"I thought here, and is the 30% tax on winnings included in the accumulative part of the pension?"
You need to understand the tax laws of the country in which you live. With the win you pay the VAT, which is deciphered as the income tax of individuals, chapter 23 of the Tax Code of the Russian Federation, this tax has nothing to do with the pension fund. NDFL is taxed almost all your income, obtained both labor and non-labor. The tax is withheld from the amount of your income by the tax agent. the legal entity that pays you this income. If the tax agent cannot withhold the tax from you, you must report the amount of income received at the end of the year to the tax inspectorate and pay the VAT to the budget on your own.
Deposits on the cumulative part of the pension belong to the category "insurance contributions", chapter 34 of the Tax Code of the Russian Federation. The cost of any winnings and prizes received in competitions, games and other events is not subject to taxation of insurance premiums. Insurance contributions are calculated on payments made within the framework of labor contracts, as well as contracts of a civil-legal nature. And these contributions are not deducted from your income, but are paid at the expense of the employer.
