For digital nomads & remote workers in Portugal
Moved to Portugal? Here's how the tax side works.
You came for the weather, the food, and the community. Then you discovered you need a NIF, have to register as a trabalhador independente (self-employed worker), issue certified invoices, and figure out Portuguese VAT and Social Security. Descodify walks you through every step and handles the admin - so you can focus on your work.

The setup journey - step by step
Every digital nomad working legally in Portugal goes through the same steps. Here's the path and what each step means.
Get your NIF (tax number)
Your NIF (Número de Identificação Fiscal) is a 9-digit number that identifies you to the Portuguese tax authority. You need it for everything - opening a bank account, signing a lease, and issuing invoices. You can get one at a local tax office (Servico de Financas) or through a fiscal representative.
Open activity (abrir atividade)
Before you can invoice, you need to register your freelance activity on the Portal das Financas. You pick a CAE code (activity category) that describes what you do - e.g., consulting, software development, design. This puts you under the regime simplificado (simplified tax regime), which is how most solo entrepreneurs are taxed.
Start invoicing
Every payment you receive from a client needs a certified invoice - a fatura or recibo verde. If your clients are outside Portugal (as most digital nomad clients are), the VAT rules are different from domestic sales. Descodify handles this automatically.
Handle VAT (IVA)
VAT treatment depends on where your client is. Services to businesses in other EU countries are typically VAT-exempt (reverse charge). Services to clients outside the EU are also exempt. Services to Portuguese clients carry 23% VAT. Once you cross the VAT exemption threshold, you register for VAT quarterly declarations. Descodify tracks all of this.
Social Security (Segurança Social)
You get a 12-month exemption when you first open activity. After that, contributions kick in - calculated as a percentage of your declared income from the previous quarter. The amounts can surprise people. Descodify tracks what you owe so there are no surprises.
What catches people off guard
These are the things digital nomads in Portugal wish someone had told them sooner.
The 15% expense proof rule
Under the regime simplificado, the tax authority assumes 25% of your income is expenses (for most service-based activities). But you need to prove at least 15% of your income in actual expenses - with invoices that have your NIF on them. If you mostly work from home with a laptop and few local expenses, hitting that 15% is harder than you think. Not meeting it means paying more tax.
Social Security after 12 months
The first year is free. Then contributions start, based on 70% of your average quarterly income. For someone earning a comfortable remote salary, contributions can easily reach several hundred euros per month. Many people budget for year one and get caught off guard in year two.
VAT rules for services to clients abroad
If you sell services to a business in the EU (B2B), you typically don't charge Portuguese VAT - the client's country handles it through the reverse charge mechanism. For clients outside the EU, services are also VAT-exempt. But you still need to track this correctly and include the right legal references on your invoices. Getting it wrong means issuing incorrect invoices.
The first-year tax discount - and why January matters
New trabalhadores independentes get a 50% discount on their taxable income in the first year and 25% in the second. But the "first year" is the calendar year you open activity - not 12 months from your start date. Open activity in November and you only get two months of the 50% discount. Open in January and you get the full year. This is worth planning for.
