Freelancing from another country raises a core question: where and how to pay tax legally. That shapes risk, comfort, and long-term stability. Below: residency basics, business forms, and typical remote setups.

Tax residency

You usually pay income tax in the country where you are tax resident. The common test is 183 days in a calendar year — above that, many countries treat you as resident and tax worldwide income. Some add “centre of vital interests” or citizenship tests. If you live in Georgia or Portugal more than half the year, you are typically resident there and should declare there — subject to overlap with your previous home country’s rules. Check both sides.

Sole trader, company, self-employed

In your country of residence you might work as self-employed (where regimes exist), as a sole trader, or through a company. Each has different rates, filings, and caps. Self-employment can simplify accounting; sole traders and LLCs add flexibility at higher income. Some countries favour local companies for profit tax vs personal rates — depends on income and plans.

Client contracts

Legality means contracts and facts align: you work from your place of residence, money lands on your account (personal or business), income is declared. Cross-border client agreements should state scope, payment, details, and governing law where relevant. Receiving foreign transfers is usually fine if declared. Fake offshore residency without real presence creates risk.

Double taxation

If ties or income span two countries, both might claim tax. Double tax treaties (DTTs) assign taxing rights and often credit tax paid abroad. When you move, check if a DTT exists between your new residence and client or former home countries and how your income type is treated.

Country examples

Georgia: 183+ days often means residency; foreign-sourced freelance rules have been favourable — verify current law. Portugal: former NHR-style benefits changed — check live rules. Spain: DNV may allow a special fixed rate band. Montenegro, Serbia: relatively low personal rates. Rules change — local advisers are essential.

Practical tips

Fix your tax residency based on real stay and local tests. Track days and keep evidence (tickets, leases, statements). Pick a legal form that matches income. Use clear client contracts and keep records. File on time in your residence state; use DTTs where applicable. A one-off consult often saves more than it costs.
