Kosovo
We don't yet have a researched, Kosovo-specific page. The points above are the general international pattern for prop-firm payouts — always confirm the exact rules with a local tax professional.
Typically self-employment / independent-contractor (business) income — not personal capital gains, since you are paid a profit-share for performance on the firm's capital.
Your country's personal income tax rates (progressive in most countries).
Self-employment / social-security contributions may apply on top of income tax.
Usually you register as self-employed / a sole proprietor and self-assess; business expenses are often deductible.
Crypto (USDC) payouts are generally taxed at their local-currency value on the date you receive them; a later sale can be a separate event.
