Crypto Gains Tax Thailand: What You Really Pay and How to Stay Legal

When you sell Bitcoin, swap tokens, or earn staking rewards in Thailand, you’re likely subject to crypto gains tax Thailand, a tax on profits from cryptocurrency transactions enforced by the Thai Revenue Department. Also known as cryptocurrency income tax, it applies to any trade that results in a profit—whether you convert crypto to fiat, trade one coin for another, or use crypto to buy goods. This isn’t a gray area. The Thai government treats crypto like property, not currency, and any gain is taxable as income.

Most traders don’t realize that even swapping Ethereum for Solana triggers a taxable event. If you bought ETH at $2,000 and sold it for SOL worth $2,800, you owe tax on the $800 profit. The same rule applies to staking, airdrops, and mining rewards—anything you receive and later sell or trade counts. The tax rate? Personal income tax, a progressive rate from 5% to 35% in Thailand based on your total annual earnings. There’s no separate crypto tax rate; your crypto profits get added to your salary, business income, or other earnings and taxed at your top marginal rate. And yes, the Revenue Department now has tools to track on-chain activity. They’ve partnered with exchanges operating in Thailand and can request wallet data from foreign platforms if needed.

Reporting isn’t optional. You must file a Personal Income Tax Return (PND 90 or PND 91) by March 31 each year, including all crypto transactions from the prior year. Many traders think if they never cashed out to Thai Baht, they’re safe—but that’s false. Even converting crypto to another crypto counts. The key is tracking your cost basis: when you bought, how much you paid, and what you sold it for. Without records, you’re guessing—and guessing in front of tax auditors is risky. Tools like Excel or crypto tax software help, but the burden of proof is on you.

What about losses? You can offset crypto losses against crypto gains in the same year, but not against other income like your salary. If you lost money on 10 different coins but made a profit on one, you only pay tax on the net gain. No carryforward of losses to future years is allowed, so timing matters. And if you’re a frequent trader? You might be classified as a business, which means higher taxes and stricter recordkeeping rules.

There’s no legal way to avoid this tax—only ways to manage it. Don’t fall for scams promising "crypto tax loopholes in Thailand." Those are just new ways to get fined. The real strategy is accurate tracking, timely filing, and knowing what counts as income. The posts below show real cases: how people got caught, how some traders legally minimized liability, and what happens when you ignore the rules. You’ll find breakdowns of actual transactions, audit examples, and clear steps to file correctly. No theory. No guesswork. Just what works in Thailand right now.
