Bootstrapping a Startup in Portugal: Setting Up an Lda - the Costs, the Benefits, and the Possibilities

This is Part 2 of Bootstrapping a Startup in Portugal, a first-person account of forming and running a Unipessoal Lda as a foreign founder in Portugal. Part 1 looked at the IRC tax structure before formation. This one is about what I actually decided, after the formation saga and after the first CC conversation. Not advice.

---

The certidão permanente arrived on a Thursday afternoon. Fifty-seven days after the first company-name submission. I had a legal entity.

Part 1 of this series ended on the cliffhanger of going to find a contabilista certificado. This post is what got decided in that conversation, and in the months of operating the company since.

Why I actually formed the Lda

There were three reasons. They're not equally important.

Liability came first. I'm building a product where getting things wrong has real financial consequences for users. A miscalculated VAT declaration, an incorrect IRS filing, a missed deadline. If the product causes a user to pay a fine they shouldn't have paid, I want a legal structure that doesn't expose my personal assets directly. A trabalhador independente (TI) running the same product has no separation between personal and business liability. An Lda contains it. That's the reason.

Optionality came second. A Unipessoal Lda is a sellable asset. A registered TI activity is just you. If someone wanted to buy Descodify, they can buy the company. There's also a path to adding a co-founder or an investor later that a TI structure doesn't have, at least not cleanly.

Tax came third, and honestly as a rounding error in the early years. The headline claim you'll read is that an Lda pays IRC at 15% on the first 50,000 euros of taxable income, while a TI on the IRS simplified regime faces progressive rates climbing toward 48%. That's technically true but not the whole picture. Money extracted from an Lda gets taxed again. Salary comes with IRS at progressive rates plus Social Security (34.75% total). Dividends come with a 28% flat rate. The Lda's low corporate tax doesn't mean a low total tax bill once you factor in extraction.

If you're forming an Lda specifically to cut your tax bill, you'll be disappointed in the early years. The math starts to work in your favour once you're generating enough revenue to leave a meaningful portion inside the company and reinvest it. At startup scale, tax is roughly neutral at best.

Regime geral, not simplificado

This one I actually settled in my own research before the CC conversation, and he agreed.

Year one is a spending year. The product was in development for months before any revenue arrived, and early-stage infrastructure costs are real. Under the IRC regime simplificado, you owe corporate tax on a deemed percentage of your gross revenue regardless of what you actually spent. If the business runs at a loss, you still owe something. Under the regime geral, a loss carries forward for five years. I expect to run at a loss in year one, and that carry-forward means the loss isn't wasted.

The other reason is the 3-year lock-out. If you opt into the simplificado and then want to renounce it, you're stuck for three years. Starting on regime geral keeps options open.

The mechanics: for a PME in 2026, the regime geral applies 15% on the first 50,000 euros of taxable profit and 19% above that. Plus a municipal derrama that varies by municipality, up to around 1.5%.

Worked example. Say the company generates 80,000 euros revenue in year two, with 25,000 euros of deductible expenses. Taxable income: 55,000 euros. IRC: 15% on the first 50,000 = 7,500 euros, 19% on the remaining 5,000 = 950 euros. Total IRC: approximately 8,450 euros before derrama.

How does that compare to the simplificado? It depends entirely on which coefficient applies. That's the unresolved question from Part 1.

• If the activity is classified under alínea b) (Art. 151 professions including code 1332 "Programadores informáticos"): coefficient 0.75. Taxable income: 80,000 × 0.75 = 60,000 euros. IRC: 50,000 × 15% + 10,000 × 19% = 7,500 + 1,900 = 9,400 euros.
• If classified under alínea c) (other services, code 1519): coefficient 0.10. Taxable income: 80,000 × 0.10 = 8,000 euros. IRC: 8,000 × 15% = 1,200 euros.

The gap between those two paths is enormous. At 0.10, year one gets the startup bonus (coefficient halved to 0.05), so that first-year bill drops to about 600 euros. At 0.75, there's no startup bonus, and the bill starts at 9,400 euros from day one regardless of profit.

My CC didn't make a case for the 0.10 classification. His advice was simpler: for a startup expecting a loss in year one, regime geral is the simple, predictable choice. It also makes the classification question irrelevant until the business is generating enough profit to make the comparison material.

The same logic applied to VAT. I registered for normal quarterly VAT from day one, rather than starting on the Art. 53 exemption and switching later. Switching mid-growth is friction I didn't need.

The real overhead

Two costs are mandatory before the business generates a single euro.

The CC. A Lda is legally required to appoint a contabilista certificado within 15 days of the NIPC being assigned. No workaround, no self-filing option like TIs have. My CC costs 120 euros per month at the moment, at a lighter scope (low-volume, read-only review, no payroll). That will rise as the business grows and payroll comes in. Call it approximately 1,440 euros per year at current scope.

Sócio-gerente Social Security. Registration as gerente is mandatory. I'm currently taking zero salary. But at zero salary, Social Security doesn't just let that slide. The minimum base is imputed at 1 IAS (the Indexante dos Apoios Sociais, €537.13 (2026) per month). The SS rate is 34.75%: 23.75% company-side plus 11% personal-side. At the 1-IAS floor:

€537.13 × 34.75% = €186.66 per month, or approximately 2,240 euros per year.

In my own case, though, this most likely falls away. I keep an active TI activity that already contributes to Social Security above the minimum, and under the acumulação rules (Art. 283 of the Código Contributivo) a gerente taking zero salary who already contributes that way can have the gerente contribution waived. It's a question for the CC, and it's the same provision that turns into an either/or under health insurance below. So budget the full 186.66 a month if the Lda is your only activity; in my situation it most likely drops out.

Together, for a gerente with no other activity: around 3,700 euros per year before the business has generated a single euro of revenue. That's the real baseline overhead of running a Lda in Portugal at the minimum scale. In my own case, with the gerente SS most likely waived through acumulação, it's closer to the 1,440 euros of CC fees alone.

Health insurance and other benefits, and whether to take a salary yet

There are two of us running the company, both gerentes and both owners, and while the company is still pre-revenue the salary question is wide open. Not just how much to pay ourselves, but whether to pay ourselves a salary at all yet, or both stay on zero. It has more moving parts than I expected.

The case for zero is the obvious one. Every euro of salary is cash leaving a company that isn't earning any, with Social Security stacked on top (34.75% in total: 23.75% company-side, 11% personal). And if you keep a separate trabalhador independente activity running alongside the gerente role, the acumulação rules can waive the gerente Social Security entirely, as long as you take zero salary (Art. 283 of the Código Contributivo). Zero salary, SS waived, nothing out the door. Lean and simple.

The case for paying ourselves is that a salary is the key that unlocks the company's benefit suite, and some of those benefits are worth real money even at this size. The meal card is one; you can only issue meal cards if there's an actual salaried worker. Pension and disability entitlements build on the contribution base. And the headline one is health insurance.

Portugal has a tax incentive for company-provided health insurance under Art. 43 CIRC and Art. 2-A(e) CIRS: structured correctly, the premiums are fully deductible for the company and not taxed as income for the workers. The condition that decides everything is that the benefit has to be offered on identical terms to the "generality of workers" (generalidade dos trabalhadores). That's not a fuzzy phrase. The AT has binding rulings on it, including PIV 25701 and PIV 17196. A single sócio-gerente who is also the sole owner doesn't constitute a "generality of workers"; the premium is then deducted only as an ordinary Art. 23 expense and taxed as a benefit in kind on the recipient, and the advantage disappears. Two genuinely remunerated workers pass the test, though, and with two of us on equivalent terms the company can deduct the premiums and we pay no IRS on the benefit. The ceiling is 15% of total payroll, or 25% if neither of us has a Social Security pension entitlement, and under Art. 43(2)(b) the cover can extend to spouses and dependent children, not just the workers themselves.

So the two paths are mutually exclusive, and that's the crux. The acumulação waiver needs us on zero; the benefit suite, health insurance and meal card and pension accrual alike, needs genuine remuneration, because a zero-euro gerente fails the generality test's implicit requirement of real pay. It's the SS waiver or the benefits, not both.

There's also a tax angle that, in my case, tilts toward paying a salary. I'm still on NHR 1.0, the original Non-Habitual Resident programme abolished for new applicants after 2024, which taxes qualifying Portuguese-source employment income at a 20% flat rate while Portuguese-source dividends get no relief and are taxed at 28%. It's tempting to read that as "salary at 20% beats dividends at 28%," but the headline gap is the least of it. Salary is a deductible company expense, which favours it; but it also drags the 34.75% Social Security behind it, which doesn't, and that can easily swamp the 8-point edge. So which extraction route wins turns far more on the Social Security position than on 20-versus-28, and it flips entirely for anyone on standard progressive IRS rates. Another numbers exercise for the CC, not a slogan.

I haven't settled it yet.

Company car, electric, probably

I'm revisiting this in about six months. Not ready to commit yet.

Three different tax advantages stack for a BEV with a purchase price at or below 62,500 euros (ex-VAT). First, the autonomous car tax (tributação autónoma) on a BEV at this price point is 0%, compared to 8%, 25%, or 32% for combustion vehicles depending on their tax cost. Second, input VAT on a BEV is fully deductible, while combustion vehicles are not deductible at all for VAT purposes. Third, the maximum cost recognized for depreciation purposes is 62,500 euros, which is the same ceiling as for combustion vehicles but which a BEV can actually reach (the combustion ceiling is 25,000 euros, low enough to exclude most cars).

62,500 euros is the load-bearing number across all three axes. Any BEV at or below that price point gets the full stack.

To make it concrete, here's a generic first-year picture for a BEV bought on the road for 40,000 euros (comfortably under the ceiling), driven around 15,000 km a year. Every line is a deductible company expense:

First-year item	Amount	Note
Purchase price (incl. VAT)	40,000 €
VAT recovered	~7,500 €	Fully deductible; a combustion car recovers nothing
Charging, ~15,000 km	~500 €/yr	About 2,700 kWh, mostly home-charged
Servicing and tyres	~500 €/yr	No oil changes, fewer wear items than combustion
Insurance	~600 €/yr
Road tax (IUC)	~30 €/yr	BEVs sit near the bottom of the scale
Autonomous tax on all costs	0 €	A combustion car pays up to 32%, plus 10 points in a loss year

So the running cost lands around 1,600 euros a year, fully deductible; the 7,500 euros of VAT comes straight back; and the car depreciates against profit up to the full 62,500-euro ceiling. The same money in a combustion car would recover no VAT, depreciate against a 25,000-euro ceiling at most, and carry autonomous tax on every euro of cost.

What personal use costs, and why for a software company it's really a benefit. Here's the honest part for a business like mine. A SaaS company has no field sales, few client site visits, no deliveries, so there's almost no genuine business mileage to point at. That matters, because it means the strictly-business position isn't realistically available to me. A company car here isn't a business tool that happens to get driven privately; it's a personnel benefit, and the honest way to run it is a written personal-use agreement with the benefit-in-kind charge attached. So the realistic case, and the one I'd actually model, is the agreement.

The agreement (acordo de utilização) puts the car at your disposal around the clock, and the personal use becomes a benefit in kind on your own income, taxed under Art. 24 of the IRS code at 0.75% of the car's market value per month, so 9% a year. That's 3,600 euros in year one on a 40,000-euro car, and it falls as the car ages. Here's the 40,000-euro BEV split across the two sides, averaged over a three-year hold so the figures line up with the totals further down.

What it costs the employee (the gerente driving it):

Employee, per year (avg over 3-yr hold)	Amount
Benefit in kind (9% of value; 3,600 € in year one)	~2,760 €
IRS at NHR 20%	~550 €
Personal Social Security (11%)	~300 €
Out of pocket	~850 €/yr (~2,550 € over 3 yrs)

For under 900 euros a year, you drive a 40,000-euro car with the charging, insurance, and servicing all paid by the company. Buying the same car privately would mean the full 40,000 euros of after-tax cash up front, plus every running cost on top.

What it costs the company:

Company, per year (avg over 3-yr hold)	Amount
Depreciation (the value the car actually loses)	~5,400 €
Running costs (charging, service, insurance, IUC)	~1,600 €
Employer Social Security on the benefit	~650 €
Autonomous tax (BEV)	0 €
Gross annual cost	~7,650 €
IRC saved (all of it is deductible)	saves ~1,150 €
Net annual cost, profitable year	~6,500 €/yr (~19,500 € over 3 yrs)

The 7,500 euros of VAT came back at purchase, so that depreciation is on the 32,500-euro net cost. In a loss year the IRC saving is deferred into the carry-forward, so the company's cost runs higher until you're in profit.

Put the two sides together: about 6,500 euros a year to the company and 850 to you, which over three years is the ~22,100-euro figure in the comparison below. The benefit in kind is taxed as employment income, so it carries both IRS and Social Security, just like salary. A real benefit, priced as one, not a way to make a private car vanish into the company.

Three ways to pay for it. The sticker price is the wrong number to compare; what matters is what each route costs across a few years. Take the 40,000-euro BEV, held three years, worth about 20,000 at the end, roughly 1,600 a year to run, in a profitable company:

Over 3 years	Buy it yourself	Company buys it	You lend the company the cash
Money comes from	your cash, or dividends	company profit	your cash, lent in (suprimento)
Car tax benefits (VAT back, depreciation, deductible running)	none	full	full
Net 3-year cost of the car	~24,800 € from cash, ~53,200 € via dividends	~22,100 €	~22,100 €
Your money afterwards	spent on a personal car (~20,000 € resale)	stays yours	repaid to you, tax-free

(These credit the car's resale value at year three, which is why the totals sit below three years of the per-year run-rate above.) The middle and right routes get the identical tax treatment; what changes is where the cash comes from and how you get it back. Buying personally is the costly one: a 40,000-euro car bought with dividend money takes about 73,000 euros of pre-tax profit to fund, the same 1.6-to-1 wedge as everywhere else in this post. The company spends pre-tax, VAT-reclaimed, deductible euros instead.

The shareholder loan is the part most people miss. Rather than make the company find the cash, you can lend it in, as a suprimento, let the company buy and run the car, and have it repay you over time. Loan repayment is return of capital: no IRS, no dividend tax. It's the one clean way to get money back out of an Lda untaxed, capped at what you put in, so it doubles as a tax-free extraction channel worth up to 28% against taking the same cash as dividends. Lend it interest-free; charging interest only creates capital-income tax for you to win the company a smaller IRC deduction. A loan over 25,000 euros wants a proper written contract, and as the sole owner you're exempt from stamp duty on it.

One honest line on the headline saving: most of the gap over buying personally is avoided dividend tax, which only counts if that money would otherwise have stayed in the company. If you would have drawn it out as pay anyway, the car-specific saving is closer to a couple of thousand euros over three years, from the VAT and the deductions alone. Reinvesting everything, as I am, the bigger number is the real one. And it still only holds because the private use is declared and the benefit-in-kind paid, rather than pretending the car is purely business.

The alternative, exclusive business use with no agreement and no benefit in kind, is the one that mostly doesn't apply to a software company. The burden of proof is yours, and the AT reads "exclusive" strictly: a declaration isn't enough; they look for mileage logs, the car kept at the company, documented client trips. For a sales or trades business that genuinely drives to customers all day, that can be real. For a desk-bound SaaS it usually can't, which is why I treat the car as a benefit rather than pretend it's a business expense. Claiming exclusivity while actually driving privately is the worst spot: an inspection that finds private use imputes the benefit in kind anyway, with penalties on top.

The catch most people miss is the daily commute. Driving between home and your regular workplace is casa-trabalho, which Portuguese tax treats as private use, not a business trip, and that holds in both directions. If the office is in Lagos and I drive there every day, that's a commute. If instead I register the company's seat at my home and drive to a coworking space in Lagos every day, the coworking is still my habitual workplace and the drive is still a commute. You can't convert a daily commute into deductible business travel by moving the registered address on paper; the AT looks at where the work actually happens, not the seat on the certidão. A genuine business trip is the occasional drive from your workplace to a client or a one-off meeting, logged as such. So a daily drive to a desk is personal use on its own, which takes the exclusive-business-use option off the table and points straight back to the written agreement and the 9% charge.

There's no pro-rata for "I only drive it privately now and then." Portugal handles that ambiguity not with a logbook tariff but with the autonomous tax, a flat presumptive charge on car costs whether or not you ever drive privately. That's exactly why the BEV is the interesting case: at 0% autonomous tax up to 62,500 euros, the usual presumptive cost is gone, which leaves the personal-use agreement as the only real lever. Even with the 9% charge, personal use still tends to beat buying the same car privately out of dividend money, because the company recovered the VAT and deducts every running euro while you're taxed on just 9% of a depreciating value. Whether it nets out ahead in my case ties back to the salary-and-SS question I still haven't settled, so it goes on the list for the CC.

There's also a secondary angle for a loss year: combustion vehicles in a loss-generating company get hit with an additional 10 percentage-point surcharge on the autonomous car tax. A BEV at 0% is immune to that surcharge.

The tax math: roughly neutral, as expected

Money inside a Lda gets taxed at corporate rates when it's earned as profit, and then taxed again when it comes out as salary or dividends. A TI pays personal income tax once, at progressive rates, on everything.

For an NHR 1.0 holder like me, the double taxation inside a Lda versus single taxation as a TI doesn't produce dramatically different outcomes at early-stage revenue levels. At higher revenue levels where IRS marginal rates climb toward 48%, the arithmetic shifts. But in year one and year two of a bootstrapped company with modest revenue, the tax cases are roughly neutral.

What changes is the structure. The Lda contains liability, enables hiring, creates a sellable entity, and separates business finances from personal ones in a way that has practical and legal significance. Those are real differences.

If someone tells you forming a Lda is primarily a tax move at startup scale, they're either talking about a revenue level where the extraction math genuinely shifts, or they're working backwards from a conclusion.

The benefit stack, and what it's actually worth

Here's the part almost nobody mentions, and the one place that "roughly neutral" verdict breaks in the Lda's favour. Once a company genuinely employs two or more remunerated workers, Portuguese law lets it hand them a stack of benefits that are deductible for the company and tax-free for the family receiving them: no IRS, no Social Security on the way out. A euro spent this way arrives whole, where a euro of dividend loses about 39% to tax first.

A generic example, not my own numbers. Take a concrete situation: a married couple who both work in the company as gerentes and owners, two children aged 3 and 5 in creche, and each spouse drawing a modest but genuine salary of about 1,200 euros a month (roughly 28,800 euros of combined annual payroll). Those salaries are what satisfy the "generality of workers" gate from the health-insurance section; this is the paid-salary branch of that either/or, the one that gives up the SS waiver to unlock the benefits. On top of the salaries, the company can layer:

• Meal allowance on a meal card. Up to €10.46 per working day, per person, free of both IRS and Social Security. Across roughly 220 working days and two people, that's about 4,600 euros a year reaching the household completely untaxed.
• Family health insurance. One policy covering both workers plus spouse and dependent children, fully deductible and IRS-free for the workers, within a cap of 15% of payroll. A typical family plan might run 1,500 to 2,500 euros a year, all of it tax-free value.
• Childcare vouchers (vales infância). For the two children under 7, in creche or pre-school, the company deducts 140% of the cost (a 40% uplift, no value cap) and the worker pays no IRS or Social Security on it. Say the company funds about 1,000 euros per child a year: 2,000 euros, tax-free. One honest caveat: the equivalent vales educação for children aged 7 to 25 lost that exemption back in 2018 and now count as taxable income, so the tax-free version only really works for the youngest kids.
• An electric company car. A BEV at or below €62,500 recovers its full VAT (around 7,500 euros on a 40,000-euro car), pays 0% autonomous tax, and depreciates against profit. The personal-use side is a separate question for the CC, but the company-side advantages are immediate.

Adding the recurring items up for this family: about 4,600 euros of meal cards, plus 2,000 euros for the family health plan, plus 2,000 euros of childcare vouchers, comes to roughly 8,600 euros a year, entirely free of IRS and Social Security, before the one-off car advantages on top. To put that same 8,600 euros of spending power in the family's pockets as dividends instead, the company would have to distribute around 14,000 euros of pre-tax profit, because a euro of tax-free benefit is worth roughly 1.6 euros of profit routed the dividend way.

None of this is exotic or aggressive. It's genuinely-remunerated people receiving statutory benefits the tax code is built to encourage. It's just not widely known, and it's the clearest place an Lda earns back the overhead this whole post has been adding up.

What changes versus what doesn't

Invoicing looks identical from the client's perspective. Both a TI and a Lda issue certified invoices through AT-certified software, with ATCUD codes, with the NIF (now NIPC rather than personal NIF) on every document. The VAT mechanics are the same.

The practical differences:

• Legal entity. The company exists separately from me.
• CC is now required, not optional.
• Monthly overhead exists even at zero revenue.
• Statutory accounts and annual filing requirements.
• Ability to hire staff and add a co-owner.
• The business is a saleable asset.

The acumulação question is still live. If I maintain a prior TI activity concurrently with the gerente role, there are contribution rules under Art. 283 of the Código Contributivo that govern how the two interact. It's not automatic, and the calculation depends on income levels in both streams. The CC needs to be involved before any TI activity is kept open alongside the company.

The whole thing, in one table

A recap of where each call landed:

Decision	Where I landed	The reason in one line
Sole trader vs Lda	Unipessoal Lda	Liability separation and optionality; tax is roughly neutral early
IRC regime	Regime geral	Year-one loss carries forward five years; sidesteps the SaaS coefficient question and the 3-year lock-in
VAT	Normal quarterly from day one	Avoids switching friction mid-growth
Accountant (CC)	Mandatory, ~1,440 €/yr	Legally required within 15 days of the NIPC
Sócio-gerente SS	Most likely waived	Acumulação: an active TI already contributes above the minimum
Salary vs dividends	Still open, SS-gated	NHR 20% makes salary a contender, but Social Security decides it, not the headline rate
Take a salary yet?	Open	Benefit suite (health insurance, meal card, pension) needs genuine salary; the acumulação SS waiver needs zero. Either/or
Benefit stack	The real Lda edge	Around 8,600 €/yr tax-free for a two-gerente family
Company car	Electric, deciding in about six months	BEV at or below €62,500: 0% autonomous tax, full VAT recovery, depreciation
