Is crypto mining legal in Portugal?
Crypto mining is legal in Portugal. There is no specific ban on running mining hardware, and the activity is treated through the tax system rather than a dedicated mining licence. As of March 2026, mining income is taxable: occasional mining is generally taxed as income, while a regular, organised operation is treated as a business activity under Category B of the Personal Income Tax Code, with progressive rates and the ability to deduct costs such as electricity and equipment. The tax authority is the Autoridade Tributaria e Aduaneira.
The rules in detail
Portugal does not prohibit cryptocurrency mining, and as of March 2026 there is no separate mining licence regime. Mining is not a crypto asset service under MiCA, so the MiCA authorisation rules that apply to exchanges and custodians do not apply to a miner who simply validates transactions and earns rewards. What matters most for a miner is the tax treatment and the ordinary obligations that come with running an electricity intensive activity, such as following grid connection rules and any local planning requirements for a larger site.
The tax outcome depends on scale and organisation. As of March 2026, mining carried out as a regular, structured activity is generally treated as self employment or business income under Category B of the Personal Income Tax Code, where net profit is taxed at progressive rates and the operator can deduct business expenses such as electricity, hardware, and depreciation. Occasional or small scale mining can fall under other income treatment. Where mined coins are received and later sold, the later disposal can also have a capital gains dimension, so keeping clear records of when coins were received and at what value matters.
Energy and practical points
Mining draws significant electricity, and Portugal has comparatively high household electricity prices within the European Union, which affects the economics of a home setup. A larger operation will deal with the standard rules for commercial electricity supply and any permits its premises require. None of these are crypto specific bans, but they shape how and where mining is viable. This page does not assess whether mining is worthwhile, only how the law treats it.
As of March 2026, mining income in Portugal is generally taxed under Category B as business or self employment income at progressive rates, with deductible costs, when carried out regularly. Social security contributions can apply to a self employed miner. Occasional mining may be treated differently. A later disposal of mined coins can also be taxable. These outcomes depend on your full circumstances, so verify the treatment with the Autoridade Tributaria e Aduaneira or a qualified Portuguese tax professional before you file.

The tax authority is the Autoridade Tributaria e Aduaneira (AT). Market supervision of crypto services sits with the Banco de Portugal and the CMVM, though these do not regulate mining itself.
