Starting a company in a different country like Delaware in the US or Estonia for lower taxes or other benefits is common, but it’s not just about where your clients are. Key factors include the legal and tax implications in both the country where the company is registered and where you’re resident (Portugal in your case). You don’t necessarily need to operate the business or have a co-founder in that country, but you should consider where your company will be deemed as having its tax residence, which is often where the key management decisions are made.
Portugal will have its own rules about foreign income and companies, especially if you’re a tax resident there. So, if your company is abroad but managed from Portugal, it might still be liable for taxes in Portugal. Each country has different treaties and laws regarding foreign-held companies and income, so it’s essential to consult with a legal and tax expert in both Portugal and the country where you plan to register your company. This will help you navigate the complex legalities and make the most informed decision.
