Working as Both an Employee and a Freelancer in Portugal - Tax Guide 2026

A surprisingly common situation among Portuguese workers - and especially among expats - is having both a salaried job and freelance income in the same tax year. A salaried developer who consults on weekends. A teacher who tutors privately. A doctor with a hospital contract who also has a private practice. A designer with a day job who freelances at night.

It’s perfectly legal. The Portuguese system has a name for it - englobamento - and a specific set of rules in CIRS (the IRS code) for how to combine the two. This guide walks through exactly how the math works, the year-1 trap that catches people off guard, and the worked example for a typical “salary + side gigs” situation. (For the underlying bracket math and the first-year freelancer benefits that Cat A income blocks, see those dedicated guides.)

How common is this?

Not rare at all:

• ~10-15% of the Portuguese workforce has some Cat B (freelance) income alongside Cat A (salary)
• Among professional expats it’s likely higher - many keep remote freelance work while taking PT employment, or vice versa
• The legal mechanism for combining them has existed since the early CIRS

The categories: Cat A and Cat B

Portuguese tax law sorts personal income into categories. Two matter for this guide:

Category	What it is	How it’s reported
Categoria A	Employment income - salary, bonuses, in-kind benefits	Anexo A of Modelo 3, fed by the employer’s monthly DMR filing
Categoria B	Self-employment, professional services, sole-proprietor income - anything billed via recibos verdes	Anexo B of Modelo 3, you fill it in based on your invoices

Other categories exist (E for capital, F for property, G for capital gains, H for pensions) - but for most working people, A and B are the two that matter.

The mechanism: englobamento

CIRS article 22 establishes the principle of englobamento (literally “lumping together”): when computing your annual IRS, all your incomes from different categories get combined into one taxable base before applying the progressive brackets.

It’s not “tax Cat A separately, then tax Cat B separately, then sum.” It’s:

1. Cat A taxable = Cat A gross − €4,587 specific deduction
2. Cat B taxable = Cat B gross × activity coefficient
3. Combined taxable = Cat A taxable + Cat B taxable
4. IRS = applyBrackets(combined taxable, with family quotient if applicable)
5. Subtract deductions à coleta to get final IRS owed

Why this matters: progressive brackets apply to your TOTAL income, not each source separately. Adding €20k of freelance income on top of a €40k salary doesn’t get taxed at the bracket rate for €20k alone - it gets taxed at the marginal rate for the €40k-€60k slice, which is much higher.

The year-1 trap

Here’s the rule that catches people off guard: if you’ve been a freelancer for less than 3 years, you may have heard about the year-1 IRS reduction - your taxable base is halved (CIRS art. 31, n.º 10). It’s a meaningful benefit; for a €30k freelancer it can mean €2,500+ saved.

It does not apply if you also have Cat A income in the same year.

CIRS art. 31, n.º 11 explicitly excludes any taxpayer who has Cat A salary income or pension income from the year-1 / year-2 reductions. The reasoning from the legislator was that the reduction is meant to help people transitioning to full-time freelancing, not to subsidize moonlighting.

What this means in practice:

• Started a salaried job in March 2026
• Also did €15k of freelance work that year
• Your first declared year as a freelancer is 2026
• You don’t get the 50% reduction - you pay full IRS on 75% × €15k = €11,250 base
• The benefit is gone for 2026 entirely. You can claim year-1 reduction in a future year only if you have NO Cat A income that year.

The TAXCLARA calculator handles this correctly: when you enter a “side salary income” alongside freelance, the year-1 toggle becomes inert (the reduction won’t apply even if checked).

Social Security: the trickier part

Both Cat A and Cat B trigger Social Security contributions, but on different bases:

Category	SS rate	Contribution base
Cat A (employee)	11% (employee side) + 23.75% (employer side)	Gross salary, no cap below ~€87k
Cat B (freelancer)	21.4% (you pay it all)	70% of declared gross, bounded by 1.5×IAS to 12×IAS monthly

Contributions are paid independently per category - you don’t get a discount on Cat B SS just because you’re already paying Cat A SS. This is one of the genuine costs of doing freelance work alongside a salary: you’re paying two SS streams.

There’s one mitigation: the first-year SS exemption (CRC art. 145) for freelancers still applies if you’re newly opening freelance activity, even if you already have a salaried job. The exemption is for the freelance side specifically, not contingent on having no Cat A income. So a salaried employee who opens their first freelance activity gets:

• ✅ First 12 months of Cat B SS contributions exempt
• ❌ No year-1 Cat B IRS reduction (Cat A blocks it)
• ✅ Cat A salary continues normally (employer SS, IRS withholding, etc.)

Worked example: €40k salary + €20k freelance

You earn €40,000 gross from your day job. On the side, you bill €20,000 in recibos verdes for consulting work. Both in the same calendar year. Single, no dependents, professional-services activity coefficient (0.75), expenses justified, standard regime.

Step 1: taxable bases

Source	Calculation	Taxable
Cat A salary	€40,000 − €4,587 specific deduction	€35,413
Cat B freelance	€20,000 × 0.75 (year 3+ coef, blocked from year-1 even if first year)	€15,000
Combined	sum (englobamento)	€50,413

Step 2: IRS via progressive brackets

€50,413 falls in bracket 8 (€46,566 - €86,634) at 44.6% marginal:

IRS = €50,413 × 44.6% − €8,441.72 = €22,484.20 − €8,441.72 = €14,042.48

Step 3: Solidarity surcharge

€50,413 < €80,000 → €0 surcharge.

Step 4: Social Security

Source	Calculation	SS
Employee (Cat A 11%)	€40,000 × 11%	€4,400
Freelancer (Cat B 21.4% × 70% of €20k)	€14,000 × 21.4%	€2,996
Total		€7,396

Step 5: Net

Component	Amount
Total gross	€60,000
IRS	−€14,042
SS	−€7,396
Net	€38,562
Effective tax rate	35.7%

Compare to alternatives

What would the same total income look like under different structures?

Configuration	IRS	SS	Net	vs Mixed
Mixed (€40k + €20k)	€14,042	€7,396	€38,562	(baseline)
Pure employee €60k	€18,318	€6,600	€37,843	−€719
Pure freelancer €60k (year 3+)	€11,652	€8,988	€39,360	+€798

Mixed sits between them. The salary side is actually slightly cheaper IRS-wise (specific deduction beats the 0.75 coefficient at this income), but the combined-bracket math hits high marginal rates earlier.

€60k total income - three income structures

Same total gross, three configurations. Pure freelance wins narrowly because of the 25% expense presumption.

Pure freelance €60k Year 3+ standard

€39,360

Mixed (€40k + €20k) Englobamento

€38,562

Pure employee €60k Single-source

€37,843

Practical implications

When a side gig actually pays after tax

If your salaried job lands you in bracket 7 (43.1%) or 8 (44.6%), every additional €1 of freelance income gets taxed at that high marginal rate, plus 21.4% × 70% = ~15% Cat B SS. So the marginal tax on side income for a high-earning employee is roughly 57-60%.

For a €1,000/month side consulting gig, that means:

• Gross: €12,000/year
• After tax: ~€4,800-€5,200
• After business expenses: even less

Side gig at marginal 60% wedge

€4,800 net

It’s still worth doing for many - building portfolio, learning, side savings - but the after-tax economics are sometimes a wake-up call.

Mixed-mode SEO opportunity for accountants

Most Portuguese contabilistas charge 5-15% more for clients with both Cat A and Cat B because annual filing involves both Anexos and reconciling withholding vs settlement on the salary side too. If you’re DIY-filing on Modelo 3, plan for an extra hour or two of paperwork.

Auto-IRS doesn’t fully handle mixed income

Portugal’s Auto-IRS pre-fill works for simple Cat A only. As soon as you have Cat B, you need to manually fill Anexo B and (usually) opt out of Auto-IRS entirely. The system will warn you.

Run your scenario

The TAXCLARA calculator handles mixed-source income directly. Pick your primary income type (Employee or Freelancer), then use the “Side income” field to add the other source. The math automatically:

• Switches to englobamento (combined progressive brackets)
• Blocks the year-1 IRS reduction when Cat A income is present
• Sums SS contributions independently per category
• Applies the family quotient for sole-earner couples on the combined base
• Honors all the normal regime selectors (NHR, IFICI, qualifying activity share)
