Accounting in Portugal: What You Need to Know Before Doing Business

Doing business in Portugal? Then you need to understand how accounting works here. Whether you’re launching a startup, freelancing, or expanding your company to this beautiful corner of Europe, getting your accounting right is not just a good idea—it’s essential. Mistakes can cost you, and not just in fines.
Let’s break it down—no fancy words, just simple, real advice you can use.
Why Accounting Matters in Portugal
Accounting isn’t just about filing taxes. In Portugal, it plays a big role in how your business runs daily. It tracks your expenses, handles payroll, pays VAT, and ensures you’re legally compliant. Every invoice, every purchase, and every euro earned or spent needs to be recorded and reported correctly.
And if you’re new here, you’ll quickly notice that accounting in Portugal comes with its own set of rules.
The Basics You Need to Know
Portugal follows the Sistema de Normalização Contabilística (SNC)—this is the local version of International Financial Reporting Standards (IFRS). So, if you’re used to accounting in another country, don’t assume the same rules apply here.
Here’s what every business owner in Portugal should keep in mind:
You need a certified accountant. It’s not optional. Portuguese law requires all businesses to appoint a Contabilista Certificado (certified accountant).

Invoices must follow specific formats. If you’re sending bills to clients, they must be generated through certified invoicing software.

VAT (IVA) is a big deal. You’ll need to understand when to charge it, how much to charge (usually 23%), and when to file your returns (monthly or quarterly).

You have filing deadlines. For example, your annual return (IES) must be submitted by July, and there are monthly obligations too, like the SAFT file submission and VAT declarations.

This might sound like a lot—and it is. That’s why many people turn to Portugal accountants to manage the heavy lifting.
Who Needs a Portugal Accountant?
Honestly, just about everyone. Even if you’re a solo freelancer working from your laptop in Lisbon, you’ll benefit from having someone who knows the ins and outs of the system.
Here’s why:
They keep you compliant. No guessing, no mistakes.

They save you time. Focus on your business, not your books.

They optimize your tax payments. You shouldn’t pay more than you have to.

If you’re trying to do it alone, one missed filing or a miscalculated tax can lead to penalties. Hiring a professional might cost a bit upfront, but it can save you a lot in the long run.
What to Look for in a Good Accountant
Not all accountants are created equal. When you’re searching for Portugal accountants, here are a few things to keep in mind:
They must be certified. Always ask for their registration number.

Communication matters. Choose someone who can explain things in simple terms and is responsive to your questions.

They understand your type of business. Whether you run a tech startup, a café, or work as a freelancer, your accountant should have experience in your area.

They speak your language. If you’re not fluent in Portuguese, working with someone bilingual can make your life much easier.
