Golden Finance reports that the United States, United Kingdom, and European Union are strengthening tax regulations on cryptocurrencies, which have significant implications for investors. In the United States, cryptocurrencies are considered digital assets, and the sale or trade is subject to capital gains tax, with rates depending on holding period and income level; miners and staking rewards are subject to income tax, and starting in 2025, exchanges will be required to report user data. In the United Kingdom, the sale or exchange of crypto assets is subject to capital gains tax, with rates reaching up to 24% and an annual tax-free allowance of £3,000; mining income and crypto salary income are subject to income tax and national insurance contributions. In the European Union, tax rates vary by country, for example, Germany exempts holdings over one year from taxes, while Spain's rate is as high as 28%; the MiCA regulation, effective in 2025, will unify some rules and enhance tax transparency.
