David is a freelance software developer. When he registered as an independent worker, the first piece of advice his father gave him was: “Get a good accountant.” He followed it. He paid €180 a month for two years — more than €4,000 in total.
At the end of the second year, a friend who works in finance asked him what the accountant actually did. David listed it out: he submitted the quarterly VAT declaration (always zero, because David invoiced under €15,000/year and was exempt), handled the Social Security declaration, and did the IRS return in June.
“You know you could do all of that yourself with an app, right?” his friend said.
David did not know. And he was far from alone.
What a certified accountant costs in Portugal
The market for accountants serving independent workers in Portugal is more varied than it looks. Prices depend on several factors: location, the client’s invoicing volume, the complexity of their tax situation, and what is or is not included in the package.
Broadly, prices fall into three tiers:
Basic service (declarations only): €50–100/month. Covers certified invoicing, quarterly VAT and Social Security declarations, and the annual IRS return. No email support, no consultations, no proactive reminders. Works for those with a simple situation who want to do nothing themselves.
Intermediate service (with support): €100–200/month. Includes the basic service plus email or phone access for one-off questions, deadline reminders, and some basic tax planning (for example, alerting you when you are approaching the €15,000 VAT exemption threshold).
Full service (consultancy): €200–400/month. For those with international clients, complex deductible expenses, or mixed income situations (for example, freelance activity combined with a company directorship). Includes regular meetings, proactive tax analysis, and management of non-standard situations.
The decision table
When an accountant genuinely makes a difference
There are situations where the cost of an accountant is justified not just for convenience, but because of real complexity.
International clients. If you work for VAT-registered businesses in other EU countries, there are additional obligations: recapitulative declarations, reverse charge rules, and potentially the need to register under VAT regimes in other countries. These are situations where a mistake costs far more than the accountant’s monthly fee.
Invoicing above €3,000/month. At this level, the impact of tax optimisations — correctly deducting expenses, planning withholding tax, potentially analysing a switch to organised accounting — starts to represent figures that justify specialist advice.
Mixed income situations. If you have simultaneous income from self-employment, employment, rental income, or capital gains, the interaction between these categories can be complex. An accountant with experience in this type of situation saves you both time and money.
Significant deductible expenses. If you have expensive equipment, vehicles used for work, or other assets you want to deduct, professional validation is advisable.
The hybrid model: the best of both worlds
For most simplified-regime freelancers invoicing between €1,500 and €3,000 per month, there is an option many do not consider: the hybrid model.
The idea is straightforward: you use certified accounting software for day-to-day tasks — invoicing, expense logging, automatic quarterly declarations — and consult an accountant once a quarter (or even just once a year for the IRS) for review and specific questions.
The cost of a one-off accountant consultation is typically €80–150 per session. Compared with €150–180 per month for a continuous service, the annual difference can exceed €1,000.
What do you lose? Immediate phone or email access for one-off questions during the month. What do you gain? Autonomy, savings, and the certainty that regular obligations are being met automatically.
Sónia, an HR consultant, adopted this model in her second year of activity. “I went from €160 a month to a €100 consultation once a quarter. The IRS cost another €80. Total for the year: under €500, instead of nearly €2,000.”
5 questions to ask before hiring an accountant
If you decide to hire an accountant, do not choose based on price alone. Before signing anything, ask these five questions:
-
What is the response time for emails or messages? An accountant who takes three days to reply is not useful when you have an urgent question.
-
What is included in the monthly fee — and what is not? Some charge the annual IRS return separately. Clarify this before you start.
-
Do you have experience with freelancers in my field? An accountant used to working with designers knows which expenses are deductible; one who mainly handles retail businesses may not.
-
Do you use software with shared access? Some accountants work in systems where you can see your declarations and tax position in real time. Others work “behind the scenes” and you never see anything. Knowing where you stand matters.
-
Who alerts me to deadlines? Does the accountant send you proactive reminders, or are you expected to remember on your own?
✅ In Summary
-
A certified accountant in Portugal costs €50–200/month depending on the service included — it makes financial sense above €3,000/month in invoicing, with international clients, or when you have complex deductible expenses to optimise.
-
For simple simplified-regime freelancers, the hybrid model works well: software for day-to-day management plus a quarterly accountant consultation (~€80–150) gives you professional coverage at less than half the cost of a continuous service.
-
FIZ covers the day-to-day part automatically — certified invoicing, quarterly filings, tax estimates — so any accountant you hire can focus on strategy rather than paperwork.
