If you have considered starting a business in Portugal, the old €5,000 share-capital figure may have made formal registration feel out of reach.
That figure is no longer the minimum share capital for a Portuguese single-shareholder limited company. Under the current rules, a sociedade unipessoal por quotas can have share capital as low as €1.
But there is an important distinction: €1 is the minimum share capital, not the total cost of starting or running a business.
Registration fees, accounting, tax, Social Security and other operating expenses still matter. The right business structure depends on what you earn, what you need to spend, and what you plan to do with the profits.
1. The €5,000 barrier has changed
A sociedade unipessoal por quotas, commonly identified by the abbreviation Unipessoal Lda., is a limited company with one shareholder.
The shareholder owns the company, while the company operates as a separate legal entity. Its name must include wording identifying it as a single-shareholder limited company.
The minimum share capital can be €1. That means a founder does not need to provide €5,000 simply to satisfy the minimum share-capital requirement for this company type.
The capital is not a registration fee that disappears. It represents money contributed to the company and forms part of its initial assets.
Historical context: The €1 minimum is not a recent legal change. Portugal has allowed freely set share capital, subject to the minimum quota rules, since 2011. The old €5,000 figure should not be presented as a newly abolished requirement.
The minimum can also differ for other company types or activities subject to special rules.
2. Share capital is not the same as the cost of registration
Even if the share capital is €1, registering a company is not free.
The Portuguese government's company-registration service lists these standard registration costs:
- €220 for a company using approved articles of association.
- €360 for a company using articles prepared by the interested parties.
Urgent services can cost more. A custom company structure, legal advice or other professional services may also add to the initial cost.
Before registering, prepare a budget for the actual setup—not just the minimum share capital.
3. Should you remain self-employed or form a company?
Starting as a sole trader can be appropriate for a small activity, especially when you want to test a business idea without taking on the administrative obligations of a company.
In Portugal, the simplified IRS regime for business and professional income generally applies when annual gross Category B income is no more than €200,000 and you have not opted for organized accounting, subject to the applicable rules.
This is a gross-income threshold. It does not mean that every person earning less than €200,000 should automatically remain self-employed, nor does it mean that every person above it should immediately incorporate.
Your net profit, personal tax position, type of activity and business expenses all matter.
For example, two businesses with the same annual revenue can have very different results if one has substantial operating expenses and the other has very few.
4. Why net profit matters more than turnover
Turnover tells you how much money your business brings in before expenses.
Net profit tells you what remains after business expenses. That is a more useful starting point when comparing business structures, although it is not the only factor in the tax calculation.
A company may pay corporate income tax on its taxable profits. If you later distribute those profits to yourself, personal tax may also apply.
If you leave profits inside the company for business purposes, the timing and treatment of personal taxation may differ. However, retained profit is not automatically tax-free, and company money is not the same as your personal money.
The financial comparison needs to consider:
- Your expected annual profit and its stability.
- The tax treatment of your current activity.
- The cost of company accounting and administration.
- Social Security obligations.
- Whether you need to withdraw most profits for personal living expenses.
- Whether you plan to reinvest profits in the business.
There is no universal €25,000 or €30,000 profit threshold at which incorporation automatically becomes cheaper. That crossover must be calculated for your circumstances.
5. The corporate tax rate is not your personal tax rate
Portugal's corporate income tax is known as IRC.
Under the rules introduced by Law 64/2025, the standard mainland corporate rate is scheduled to be:
- 19% for tax periods beginning in 2026.
- 18% for tax periods beginning in 2027.
- 17% for tax periods beginning in 2028.
Qualifying small and medium-sized businesses and Small Mid-Caps that meet the relevant activity and eligibility requirements may benefit from a 15% rate on the first €50,000 of taxable income for tax periods beginning in 2026, with the standard rate applying to the excess.
These are corporate tax rates—not a guaranteed rate on every euro earned by every company.
The rules depend on eligibility, taxable income and the applicable tax period. The reduced rate also does not eliminate other taxes or obligations.
6. What changes when you form a company?
A limited company brings additional responsibilities.
You generally need organized accounting and a certified accountant, known in Portugal as a contabilista certificado, to handle the company's accounting and tax reporting.
You may also need to manage:
- Company financial statements and annual tax returns.
- VAT obligations where applicable.
- Company records and bookkeeping.
- Social Security registration and contributions based on your role and circumstances.
- Separate company and personal finances.
These costs recur. That is why forming a company simply because the minimum share capital is low can be a poor decision.
Before incorporating, ask an accountant to compare the estimated total cost of remaining self-employed with the estimated cost of operating a company.
7. What if you are an immigrant living in Portugal?
If you already live in Portugal, the company-registration process and your immigration status are two separate questions.
The right to establish a company does not, by itself, settle whether your residence authorization permits a particular activity or whether additional immigration steps are required.
Check your specific residence status and business activity before making a change.
If you are outside Portugal and want to move to the country to run a business, the D2 entrepreneur or independent-activity residence visa may be relevant.
The application is assessed on its own requirements. A credible business plan, evidence of resources for the proposed activity and proof of means of subsistence can matter. Do not assume that the D2 is automatically approved because you can register a company, or that a single fixed investment amount guarantees eligibility.
Confirm the current requirements with the Portuguese consulate responsible for your application.
8. A practical way to decide
Before choosing a structure, write down these five figures:
- Expected annual turnover.
- Expected annual business expenses.
- Expected annual net profit.
- The amount you need to withdraw for personal living costs.
- The amount you expect to retain and reinvest in the business.
Then ask a certified accountant to compare the relevant tax and Social Security outcomes under the available structures.
If your income is irregular or your business is still being tested, keeping the setup simple may be sensible. If your profits are stable, you want to retain money in the business, or your commercial plans require a company, incorporation may deserve closer consideration.
The point is not to incorporate as early as possible. It is to choose a structure that fits the business you actually have.
Frequently asked questions
Can you start a Portuguese company with €1?
A single-shareholder limited company can have minimum share capital of €1. That does not mean the complete registration and operating costs are €1.
Is €5,000 still required to form a Unipessoal Lda.?
No. The minimum share capital for a sociedade unipessoal por quotas can be €1, subject to the rules applicable to the activity and company.
Is incorporation always cheaper than self-employment once profit reaches €25,000?
No universal threshold applies. The result depends on the tax position, accounting costs, Social Security, profit withdrawals and other circumstances.
Does the D2 visa require you to invest €5,000 or €100,000?
Do not rely on a single investment figure as a universal requirement. D2 applications are assessed using the applicable visa rules and the evidence supporting the proposed activity and the applicant's means.
Final thought
The old €5,000 share-capital barrier is no longer the starting point for a single-shareholder limited company in Portugal.
But a low minimum capital requirement does not make incorporation automatically worthwhile.
Calculate your actual costs, understand the tax treatment and get advice based on your business numbers before choosing a structure.
