Charity auctions

• Lottery vs charity raffle

  Lotteries need a licensed operator; a free raffle per donation is a gray zone — safer as 'every donation = a chance, no minimum'.

• Auction of items/experiences

  Selling donated lots is charitable activity; formalize lot acceptance and sale acts.

• Winner's taxes

  Raffle winnings are taxable personal income (PIT + military levy); the fund reports it.

• Transparency

  Public rules, draw date, recorded drawing — the trust standard for 'chance' mechanics.

The riskiest scheme is 'paid → got a chance at a prize': that's a lottery with real liability. Safe formats: auctions, crowdfunding with goods rewards, 'donation = opportunity' with no stake.
