The exemption that explains everything
Thailand wants to be a digital-asset hub, and it acts accordingly: capital gains from selling crypto on exchanges regulated by the Thai SEC are exempt from tax until 2029. For someone whose gains in Spain would fall under the savings tax base (19 % to 28 % depending on the bracket), the difference is obvious, and for many investors it's half the reason for the move.
But "exempt" doesn't mean "no rules apply." The exemption is specific: it covers a channel (a licensed local exchange), a type of transaction (capital gains on a sale), and a time window (until 2029). Anything outside that lives in a different box.
Local exchange vs offshore
It's the distinction that moves the most money, and the one most people overlook:
| Where you sell | General treatment | The nuance |
|---|---|---|
| Regulated Thai exchange (SEC TH) | Capital gains exempt until 2029 | The clean case investors look for |
| Offshore exchange + bringing the money in | Falls under the 2024 remittance rule | May be taxed as remitted income; depends on the year and the source |
| Staking, lending, airdrops | Not a "capital gain on sale" | May be treated as income; case by case |
| Being paid in crypto (salary, invoices) | It's employment/business income | Taxed for what it is, not for being crypto |
The practical consequence: where and when you realize the gain matters as much as how much you gain. The 2024 remittance rule — which taxes what you bring into the country as a resident — is the backdrop to all of this, and we cover it separately in the Thailand tax guide.
Before leaving Spain
The other side of the problem is Spanish tax, and it's the one that usually gets expensive through carelessness:
- The snapshot of your wallets. Document balances and acquisition cost before you stop being a Spanish tax resident. Capital held beforehand isn't income just because it crosses a border, but you need to be able to prove it.
- Form 721. The informative return for crypto held abroad is mandatory while you remain a Spanish tax resident above certain thresholds. Knowing when you stop being required to file it is part of exiting Spain's tax system properly.
- Exit tax. It only affects large portfolios of shares and holdings, not crypto in general, but it's worth ruling out before you move anything.
- CRS and CARF. Automatic exchange of financial information already covers accounts, and the CARF framework extends it to crypto-assets. Cleaning up your wallets beforehand — segregating, organizing, documenting — isn't paranoia: it's what saves you from awkward explanations two years later.
What we do (and what we don't)
We give you the map — this — and we run the move start to finish (visa, flight, arrival and apartment). For the investor relocating, having the logistics handled is usually exactly what's missing.
Frequently asked questions
Do you pay tax on crypto in Thailand?
Capital gains from selling on an exchange regulated by the Thai SEC are exempt until 2029. Outside that (offshore, staking, being paid in crypto), the treatment can change and each case needs its own look.
Does the exchange I use matter?
Yes: the exemption is for exchanges licensed in Thailand. Selling offshore and bringing the money in falls under the 2024 remittance rule and can be taxed differently. Plan where and when you realize gains before you move.
What do I do with my crypto before leaving Spain?
Document a snapshot of your wallets and your acquisition cost, review your exposure to form 721 and the exit tax, and decide when to realize gains. Cleaning up beforehand protects you against automatic exchange of information.
