Trabalhador Independente vs LDA — Quick Read 2026
Trabalhador Independente (TI) is Portugal's self-employed sole-trader status — fast to open, low overhead, taxed under IRS at progressive rates from 14.5% to 48%, plus 21.4% Segurança Social on a percentage-of-income base. Sociedade por Quotas (LDA) is a limited-liability company taxed under IRC at a flat 21% (17% on the first €50,000 for SMEs), with separate legal personality. For e-commerce sellers turning over below €40,000, TI is almost always cheaper and simpler. Above €60,000, LDA wins on tax, liability and reinvestment optionality. Between those bands the choice depends on whether you draw all profits as salary or reinvest. This guide walks through both structures end-to-end, with the legal references (Código IRS, Código IRC, CIVA, CSC) and a decision matrix at the end.

1. Trabalhador Independente — The Portuguese Sole Trader
What "Trabalhador Independente" Really Means
Trabalhador Independente (TI) — literally "independent worker" — is the Portuguese legal status equivalent to a sole trader, freelancer or self-employed individual. It is not a separate legal entity. The TI is the business: same fiscal identity (NIF), same liability, same person. Activity is opened by filing a declaração de início de atividade at Autoridade Tributária e Aduaneira (AT) via the Portal das Finanças, typically completed in under one hour at zero cost.
Once opened, the TI obtains a CAE (Classificação das Atividades Económicas) code — for e-commerce sellers, usually 47910 (Comércio a retalho por correspondência ou via Internet) — and immediately starts issuing recibos verdes for services or invoices for product sales via Portal das Finanças or any certified billing software. Portuguese AT requires SAF-T (PT) software certification for any seller exceeding €50,000 turnover, but most TIs use the free Portal das Finanças billing tool until they cross that threshold.
Who Uses TI Status in 2026
Roughly 825,000 Trabalhadores Independentes were active in Portugal at the end of 2026 (Segurança Social statistics) — about 16% of the working population. Of these, the fastest-growing cohort is digital and e-commerce: dropshippers, Amazon FBA sellers, Etsy creators, Shopify storefront operators and marketplace resellers on Worten, Fnac.pt and Continente. The status is so flexible that the same person can hold multiple CAE codes — selling handcrafts, doing freelance design work and running an Amazon storefront simultaneously, all under one TI registration.
Key Characteristics of TI Status
- Zero setup cost, same-day activation via Portal das Finanças
- No mandatory Contabilista Certificado until €200K turnover or opt-out of Regime Simplificado
- Personal and unlimited liability — personal assets reachable by creditors
- IRS Category B taxation aggregated with other personal income at progressive brackets
- First-year Segurança Social exemption for newly opened TIs (2019 reform)
2. Sociedade por Quotas (LDA) — Portugal's SME Workhorse
What an LDA Actually Is
Sociedade por Quotas, abbreviated Lda. after the company name, is the Portuguese equivalent of a GmbH (Germany), SARL (France), Ltd (UK) or S.L. (Spain): a limited-liability company whose share capital is divided into quotas (not freely tradable shares like an SA). It is governed by the Código das Sociedades Comerciais (CSC) Articles 197–270-D. Each shareholder (sócio) holds a quota; one or more shareholders manage the company as gerentes.
An LDA is a separate legal person from its shareholders. It has its own NIPC (collective tax number), its own bank account, files its own IRC tax return (Modelo 22), submits its own annual IES (Informação Empresarial Simplificada) to the Conservatórias do Registo Comercial, and — crucially — its debts are its own.
Sociedade Unipessoal por Quotas — The Solo Variant
For solo e-commerce entrepreneurs the most common structure is the Sociedade Unipessoal por Quotas (often abbreviated Unipessoal Lda.) — a single-shareholder LDA. Same IRC tax regime, same limited liability, same Contabilista Certificado obligation, but with one sole sócio. Minimum capital is €1. This is the structure most TI sellers migrate to once they cross the €60,000–€80,000 turnover band, because it preserves owner-operator simplicity while unlocking limited liability and the IRC flat rate.
Empresa na Hora — Same-Day Incorporation
Since 2005 Portugal has offered Empresa na Hora ("Company in an Hour"), a public-private service that allows LDA incorporation in approximately one business day at the Conservatórias do Registo Comercial or any participating notary. The fixed cost is around €360 including all registry fees, and the founder chooses from a pre-approved list of company names plus pre-approved articles of association (pacto social tipo). The LDA receives its NIPC, social-security identification and Segurança Social registration immediately. For e-commerce sellers, this means same-day activation in nearly all cases.
Key Characteristics of an LDA
- Setup: €360 Empresa na Hora; €600–€1,200 via lawyer with custom pacto social
- Capital: €1 per sócio (€2 standard, €1 Unipessoal)
- Contabilista Certificado mandatory — signs Modelo 22, IES and DP IVA
- Limited liability to subscribed quota (CSC Articles 78–84 director-liability exceptions)
- IRC: 21% flat, 17% on first €50K SME, + Derrama Municipal 0–1.5%, Derrama Estadual on profits >€1.5M
- Annual filings: Modelo 22 IRC by 31 May, IES by 15 July, DP IVA quarterly or monthly

3. Revenue Thresholds — When Each Structure Wins
There Is No Hard Limit for TI — But There Is a Soft One
One of the most common misconceptions is that Trabalhador Independente has a turnover ceiling. It does not. Portuguese law places no statutory cap on TI turnover. A Trabalhador Independente can legally invoice €5 million in a year if the seller is willing to pay the resulting IRS at marginal 48% (plus Segurança Social).
What exists are several soft thresholds that increase the operational and tax burden as turnover grows:
The €60K Practical Crossover
In practical terms, the inflection point where most Portuguese e-commerce sellers migrate from TI to LDA sits between €60,000 and €100,000 annual turnover. Below €60K, the combination of Regime Simplificado's 0.15 coefficient for trade (15% of sales is taxed) and modest IRS marginal rates keeps the TI tax burden well below the LDA's IRC + Segurança Social cost. Above €60K, the marginal IRS rate climbs into the 35–45% band, exceeding the LDA's 17%/21% IRC flat rate.
The exact crossover depends on three variables: (1) the seller's other personal income (an existing salary pushes the TI up the IRS brackets faster), (2) whether profits are fully distributed or reinvested (LDAs that retain earnings benefit from the flat IRC rate indefinitely), and (3) category coefficient (0.15 for trade is generous; 0.75 for services penalises consultants).
4. IRS Brackets (TI) vs IRC 21% (LDA) — The Tax Rate Showdown
How a Trabalhador Independente Is Taxed — IRS Category B
A Trabalhador Independente's business income falls into IRS Category B (rendimentos empresariais e profissionais) under the Código do IRS Article 3. The taxable income is added to any other personal income (Category A wages, Category H pensions, Category E investment income) and taxed at Portugal's progressive IRS brackets. The 2026 brackets (mainland) are:
| Taxable Income (Annual) | IRS Marginal Rate 2026 |
|---|---|
| Up to €8,059 | 14.5% |
| €8,059 – €12,160 | 16.5% |
| €12,160 – €17,233 | 22% |
| €17,233 – €22,306 | 25% |
| €22,306 – €28,400 | 32% |
| €28,400 – €41,629 | 35.5% |
| €41,629 – €44,987 | 43.5% |
| €44,987 – €83,696 | 45% |
| Above €83,696 | 48% + 2.5–5% Solidariedade (CIRS Art. 68-A) on income >€80K |
How an LDA Is Taxed — IRC Flat 21%
An LDA's profits are taxed under the Código do IRC (Corporate Income Tax). The 2026 mainland rates are:
| Component | Rate 2026 | Applies To |
|---|---|---|
| Standard IRC | 21% | All taxable profit (mainland) |
| SME reduced rate | 17% | First €50,000 profit (CIRC Article 87 nº 2) |
| Derrama Municipal | 0% – 1.5% | Set by each municipality (Lisbon 1.5%, Porto 1.5%, many rural 0%) |
| Derrama Estadual | 3% – 9% | Profits €1.5M–€7.5M: 3%; €7.5M–€35M: 5%; >€35M: 9% |
| Madeira IRC | 14.7% | Regional reduction; Madeira FZF zone even lower |
| Azores IRC | 16.8% | Regional reduction |
Typical e-commerce LDA with €80K turnover and €40K taxable profit: €40K × 17% SME = €6,800 + 1.5% Derrama Lisbon = €600 → ~€7,400 total corporate tax (effective 18.5%).
Side-by-Side at €20K, €60K, €100K Net Profit
Estimated total tax burden (income tax + social security) under each structure, mainland Portugal, no other personal income:
| Net Profit | TI Total Tax (IRS + SS) | LDA Total Tax (IRC + sócio salary) | Winner |
|---|---|---|---|
| €20,000 | ~€4,100 (20.5%) | ~€6,800 (34%) | TI saves €2,700 |
| €40,000 | ~€11,800 (29.5%) | ~€11,200 (28%) | ~Tie |
| €60,000 | ~€21,800 (36.3%) | ~€16,400 (27.3%) | LDA saves €5,400 |
| €80,000 | ~€31,200 (39%) | ~€21,600 (27%) | LDA saves €9,600 |
| €100,000 | ~€41,500 (41.5%) | ~€26,800 (26.8%) | LDA saves €14,700 |
Modelling tip: LDA "tax savings" only crystallise if you retain earnings or distribute dividends (28% participação). If you draw all profit as sócio-gerente salary you collapse most of the IRC advantage. Figures illustrative — model your case with a Contabilista Certificado. Use the Zunapro forecaster →
5. Segurança Social — The 21.4% TI Rate Explained
How TI Segurança Social Works
Trabalhadores Independentes contribute to Segurança Social at a headline rate of 21.4%, but applied to a contribution base rather than to total income. The base is calculated as:
- 70% of gross income for service activities (consulting, design, IT, freelance)
- 20% of gross income for trade, production and e-commerce activities (CAE 47910 etc.)
Because most e-commerce sellers fall under the trade coefficient, the effective Segurança Social rate on gross sales is 21.4% × 20% = 4.28%. On €60,000 of e-commerce gross sales, the TI's annual Segurança Social bill is roughly €60,000 × 4.28% = ~€2,568.
Quarterly Income Declarations
TIs declare income to Segurança Social quarterly via the Segurança Social Direta portal. Contributions are paid by the 20th of each month, based on the most recent declared income. Reform in 2019 introduced this quarterly system, replacing the older annual recalculation that frequently produced unpleasant year-end surprises.
The First-Year Exemption
Newly opened Trabalhadores Independentes are exempt from Segurança Social contributions for the first 12 months after activity opening (Lei nº 110/2009, Article 168). This is a meaningful subsidy: combined with the IVA franchise threshold (€15,000), a brand-new TI can effectively run for a full year paying only IRS, with no SS and no IVA.
How LDA Sócio-Gerente Segurança Social Differs
In an LDA, the sócio-gerente (managing shareholder) is enrolled in Segurança Social as an "Membro de Órgão Estatutário" (MOE). The contribution base is the sócio-gerente's declared monthly remuneration — set by the LDA itself, with a minimum equal to the Indexante de Apoios Sociais (IAS, ~€522 in 2026) and no statutory maximum on the contribution base. The combined rate is 34.75% (split: 23.75% employer + 11% employee).
The strategic point: by setting the sócio-gerente's monthly salary low (e.g. minimum wage of €870 in 2026), the LDA owner caps Segurança Social exposure at roughly €870 × 34.75% × 14 = ~€4,233 annually — and pays IRC on retained profits instead. This is exactly how LDAs achieve their effective tax advantage at higher income levels.
6. Limited Liability — The Real Reason to Form an LDA
The Unlimited Liability of a Trabalhador Independente
Because a Trabalhador Independente is not a separate legal entity, the seller's personal assets and the business assets are one and the same. Creditors can pursue the seller's home, car, bank accounts, salary at any other job, and inheritance — anything reachable by Portuguese civil enforcement (penhora) under the Código de Processo Civil.
For an e-commerce seller this matters in several concrete scenarios:
- Consumer warranty claims — Portuguese law mandates a 2-year statutory guarantee (garantia legal) on B2C sales under Decreto-Lei nº 84/2021. A defective batch of electronics can trigger hundreds of warranty claims aggregating into five- or six-figure liability.
- Marketplace chargebacks — Amazon, Worten, Fnac and Continente all reserve the right to deduct disputed sums from future settlements. A coordinated buyer-fraud wave can wipe out a quarter's earnings.
- Supplier disputes — non-payment to Chinese or European suppliers can result in international debt-collection or civil suits against the TI personally.
- Tax assessments — AT can pursue personal assets directly for unpaid IVA or IRS.
How an LDA's Limited Liability Works
Under the Código das Sociedades Comerciais Article 197, an LDA's shareholders are liable only up to the value of their subscribed quota. A €1 quota means €1 maximum exposure. Personal assets — house, car, savings — are shielded by the corporate veil, provided the LDA is operated as a genuinely separate entity (no mixing of personal and corporate funds, proper accounting, etc.).
Exceptions exist under CSC Articles 78–84 ("director liability"): if a sócio-gerente acts with fraud, gross negligence, or breach of legal duties — including failing to pay social security or VAT collected — the veil may be pierced and personal liability can attach. In practice, properly managed LDAs almost never see veil-piercing.
The "Liability Cost" Multiplier
For e-commerce sellers, the calculus is usually: at what point does the cost of an LDA's mandatory accounting (~€1,200–€3,600/year) become worth the elimination of personal-asset risk? Most Portuguese sellers conclude the answer is "as soon as inventory exceeds €20,000" — because at that point a single product-defect lawsuit can outstrip the LDA's annual overhead by orders of magnitude.
Risk-management tip: If you sell anything that ingests, applies to skin, conducts electricity, contains lithium batteries, or carries small children — incorporate as an LDA from day one. The math on a single product-liability claim outweighs years of TI tax savings. See LDA formation flow →
7. Regime Simplificado — The 75% Deemed-Cost Goldmine
How Regime Simplificado Works
Regime Simplificado is the default simplified IRS taxation regime for Trabalhadores Independentes with annual gross income up to €200,000 (CIRS Article 28). Instead of tracking actual costs, the system applies a fixed coefficient to gross income to determine the deemed taxable base. The taxpayer is presumed to have incurred costs equal to (1 − coefficient) × gross income.
The 2026 Coefficients
| Activity Type | Coefficient | Deemed Costs | Taxable Base |
|---|---|---|---|
| Sale of goods / retail / e-commerce | 0.15 | 85% of sales | 15% of gross sales |
| Hotel and restaurant services | 0.35 | 65% | 35% |
| Other services (consulting, IT, design) | 0.75 | 25% | 75% |
| Royalties and capital income | 0.95 | 5% | 95% |
Why E-Commerce Sellers Love the 0.15 Coefficient
For e-commerce sellers operating under CAE 47910 (retail via Internet), Regime Simplificado treats 85% of gross sales as deemed cost — only 15% becomes taxable IRS base. On €60,000 of e-commerce gross sales, the taxable IRS amount is just €9,000, taxed at the IRS brackets above (combined with any other personal income).
This is extraordinarily generous compared to organised accounting, where actual costs must exceed 85% of revenue to come out ahead — a margin almost no real e-commerce business achieves once you factor in marketplace fees, fulfillment and customer acquisition. Regime Simplificado is one of the most favourable simplified-tax regimes in the EU for retail.
The Documented-Costs Requirement (2018 Reform)
Since the 2018 IRS reform, Regime Simplificado requires that at least 15% of gross income be supported by documented expenses (invoices entered into e-fatura). Below that threshold, the difference is added to taxable income as a penalty. For e-commerce sellers this is rarely a binding constraint — marketplace commissions, fulfillment, packaging and shipping easily exceed 15% of sales — but it is worth knowing.
Opt-Out: Contabilidade Organizada
A TI can voluntarily opt out of Regime Simplificado in favour of contabilidade organizada (organised accounting), tracking actual costs against actual revenues. This is rarely advantageous for an e-commerce TI because real-world gross margins (after marketplace fees, ads, fulfillment) typically sit below the 85% deemed-cost level. Organised accounting only pays off for service businesses with high real-cost ratios.
8. Accounting Simplicity — TI vs LDA Contabilista Certificado
TI in Regime Simplificado — Minimal Accounting
A TI in Regime Simplificado has the lightest accounting burden in Portuguese tax law. Required artefacts:
- Invoice register — certified software (or Portal das Finanças if under €50K)
- Cost register — incoming invoices with seller's NIF (15% documented-expense floor)
- Annual IRS Modelo 3 + Anexo B — filed April–June by the taxpayer
- Quarterly Segurança Social declaration via Segurança Social Direta
- Quarterly DP IVA if IVA-registered (turnover >€15K)
A Contabilista Certificado is not legally required for a TI in Regime Simplificado. Many sellers self-manage in the first 1–2 years; a part-time accountant typically costs €30–€80/month once turnover passes €50K.
LDA — Mandatory Contabilista Certificado
Every Portuguese LDA must by law appoint a Contabilista Certificado (CC) registered with the Ordem dos Contabilistas Certificados (OCC), per Decreto-Lei nº 452/99. The CC signs and is legally responsible for:
- Modelo 22 IRC — annual return, due 31 May
- IES (Informação Empresarial Simplificada) — annual summary to AT, Banco de Portugal, INE and Conservatórias, due 15 July
- SAF-T (PT) annual + monthly Faturação
- DP IVA — quarterly or monthly
- Folha de Vencimento — monthly payroll declaration
Typical Monthly CC Fees in 2026
| LDA Profile | Monthly CC Fee |
|---|---|
| Dormant Unipessoal Lda | €60 – €90 |
| Micro e-commerce LDA (<50 invoices/mo) | €90 – €150 |
| Active e-commerce LDA (50–500 invoices/mo) | €150 – €250 |
| Multi-marketplace LDA (500+ invoices/mo) | €250 – €400+ |
Annualised, an active e-commerce LDA pays €1,800–€3,600 in CC fees — a fixed overhead that does not exist for a TI in Regime Simplificado, and which must be factored into the decision. Zunapro automates the marketplace-to-accounting handoff (e-fatura, SAF-T export, CC-ready feed), typically cutting CC fees 30–40% by eliminating manual data entry.

9. Migration Path — TI → LDA Without Tax Pain
When to Pull the Trigger
The most common migration trigger is the realisation, after the first full tax year, that the seller's effective IRS rate is now above 30% and growing. At that point the LDA's 17%/21% IRC flat rate becomes the cheaper structure even after Contabilista Certificado fees. Other triggers include:
- First serious consumer-warranty claim or marketplace chargeback dispute
- Hiring the first employee (LDAs make payroll cleaner than TI Category B)
- Plans to take outside investment (only an LDA can issue quotas to investors)
- Inventory crosses €25,000 carrying value (liability exposure)
- Crossing the €200K Regime Simplificado ceiling
Step-by-Step Migration Flow
- Incorporate the new LDA via Empresa na Hora (1 day, €360); pick Unipessoal if solo
- Declare CAE codes — same as your TI (e.g. 47910) so the LDA inherits the operational identity
- Register IVA + SAF-T (PT) — most certified tools support entity migration with one toggle
- Open the LDA bank account for share-capital deposit and operational separation
- Transfer inventory via trespasse (tax-neutral under CIRS Article 38) or sale at fair market value with IVA invoice TI → LDA
- Reassign marketplace accounts to LDA's NIPC (Amazon, Worten, Fnac, Continente)
- Close TI activity — file declaração de cessação at Finanças; personal NIF remains
- Final IRS Modelo 3 + Segurança Social for the partial year
Tax-Neutral Trespasse (CIRS Article 38)
Transfer of a TI's business to an LDA in exchange for quotas (not cash) can be tax-neutral — no capital gain crystallises, the LDA inherits the TI's asset basis. Qualifying conditions: the LDA must continue the activity for at least 5 years and the TI's quota must represent ≥50% of the LDA's capital. This is the cleanest migration path, avoiding IRS on accumulated inventory or goodwill.

10. Decision Matrix — Which Structure to Choose in 2026
The single most useful artefact for choosing a Portuguese e-commerce legal structure is a side-by-side decision matrix scored against the dimensions that actually matter. The matrix below covers ten such dimensions; the winner per row is highlighted.
The 2026 Default Recommendations
- You expect €0–€20K first-year turnover, testing a product idea → Open as TI in Regime Simplificado. First-year SS exemption + IVA franchise + 0.15 coefficient = practically tax-free runway.
- You expect €20K–€40K, modest growth → Stay TI, evaluate at year-end.
- You expect €40K–€60K with no employees and no risky SKUs → Borderline. Model both paths with a Contabilista Certificado; decision often turns on whether you have other personal income.
- You expect €60K+ or you carry inventory liability → Form Sociedade Unipessoal por Quotas (LDA) from day one or migrate quickly.
- You are taking outside investment or onboarding a co-founder → LDA is the only option — TI cannot issue equity.
- You operate cross-border with multiple EU marketplaces → LDA, because OSS and IOSS regimes work cleanly with corporate VAT registration.

🇵🇹 Start in Portugal Now →Portuguese E-Commerce Legal-Structure FAQ 2026
What is the difference between Trabalhador Independente and LDA in Portugal?
TI is a self-employed sole trader with personal unlimited liability, taxed under IRS (14.5–48%) plus Segurança Social at 21.4%. LDA is a limited liability company taxed under IRC at flat 21% (17% on first €50K for SMEs) with separate legal personality. TI wins below €60K turnover; LDA wins above that threshold and whenever liability protection matters.
Is there a revenue limit for Trabalhador Independente in Portugal?
No — there is no statutory revenue ceiling. However, Regime Simplificado ends at €200,000 turnover, above which TIs must keep contabilidade organizada with a Contabilista Certificado. In practice most e-commerce sellers transition to LDA between €60K and €100K, where the IRS effective rate exceeds the 21% IRC flat rate.
What is the IRC tax rate for LDA in Portugal in 2026?
Standard IRC 21% mainland; SMEs get 17% on the first €50,000 of taxable profit. Derrama Municipal adds up to 1.5%, Derrama Estadual 3–9% on profits >€1.5M. Madeira 14.7% / Azores 16.8% regional rates. For LDAs with profits under €50K, the blended effective rate is ~17–19%.
What is Regime Simplificado and who can use it?
Simplified IRS regime for TIs with annual gross income up to €200,000. For retail/e-commerce (CIRS Article 31), the coefficient is 0.15 — only 15% of gross sales is taxed (85% deemed cost). For services, 0.75. Automatic unless the taxpayer opts for organised accounting. Since 2018, at least 15% of income must be documented in e-fatura.
How much does Segurança Social cost a Trabalhador Independente?
TIs pay Segurança Social at 21.4% of the contribution base: 70% of declared income for services, 20% for trade and production. E-commerce TIs under CAE 47910 therefore face an effective ~4.28% rate on gross sales (21.4% × 20%). Contributions are paid by the 20th of each month from the most recent quarterly declaration. The first 12 months after activity opening are exempt for first-time TIs (2019 reform).
Does an LDA offer limited liability protection?
Yes. An LDA is a separate legal entity under the Código das Sociedades Comerciais. Sócios are liable only up to their subscribed share capital (€1 minimum per sócio). Personal assets are shielded except in cases of fraud, fund mixing, or director liability (CSC Articles 78–79). A TI has unlimited personal liability — creditors can pursue personal assets via penhora.
Do I need a Contabilista Certificado for an LDA?
Yes, by law (Decreto-Lei nº 452/99). The CC signs Modelo 22, IES and DP IVA. Typical monthly fees: €60–€90 dormant Unipessoal, €90–€150 micro e-commerce, €150–€250 active multi-marketplace, €250+ larger operations. A TI in Regime Simplificado is not required to have a CC.
Can I switch from Trabalhador Independente to LDA?
Yes — and many do once turnover passes €60K–€80K, where IRS marginal rates exceed IRC flat rate. Process: incorporate LDA via Empresa na Hora (1 day, €360), transfer activity via trespasse or sale at market value, close the TI activity (declaração de cessação), file a final IRS Modelo 3. Trespasse can be tax-neutral under CIRS Article 38 when the LDA continues the activity for ≥5 years and the TI receives quotas (not cash) in exchange.
Which is better for e-commerce: TI or LDA?
Below €40K: TI in Regime Simplificado is cheaper and simpler. €40K–€60K: depends on personal IRS bracket and reinvestment plans. Above €60K, or whenever inventory-liability exposure is significant (consumer warranties, marketplace chargebacks, supplier disputes), LDA wins on both net economics and risk protection. Multi-marketplace sellers on Amazon ES/PT, Worten, Fnac.pt and Continente almost universally operate as LDA by year two.
What is the minimum share capital for an LDA in Portugal?
Since 2011: €1 per shareholder (€2 minimum standard LDA, €1 Unipessoal) — among the lowest in the EU (Spain's S.L. needs €3,000, Germany's GmbH €25,000). Capital must be subscribed at incorporation but can be deposited within 5 days, or by end of the first fiscal year by founder declaration.
Are there VAT differences between TI and LDA?
No. IVA rules under CIVA are identical for TI and LDA: same €15,000 registration threshold, same rates (23% standard, 13% intermediate, 6% reduced mainland), same DP IVA periodicity (quarterly <€650K, monthly above), same SAF-T (PT) e-fatura export. The real differentiator between TI and LDA is income tax (IRS vs IRC) and Segurança Social, not VAT.
How does Sociedade Unipessoal por Quotas differ from a standard LDA?
Unipessoal Lda. is a single-shareholder LDA — same IRC regime, same limited liability, same CC obligation, but with one sole sócio and €1 minimum capital. It is the most common migration target for solo TIs because it preserves owner-operator simplicity while unlocking limited liability and the 17%/21% IRC flat rate. Conversion to a multi-shareholder LDA later is straightforward via quota transfer or capital increase.
Can foreign EU citizens open a Portuguese LDA or TI?
Yes. EU citizens have full freedom of establishment — get a Portuguese NIF, open as TI or incorporate an LDA via Empresa na Hora, same procedures as Portuguese citizens. Non-EU citizens typically need a residence permit, fiscal representative, or a Portuguese-resident manager. The D2 entrepreneur visa and Golden Visa programs are common routes for non-EU founders.
Does Portugal have any special tax regimes for e-commerce in 2026?
No dedicated e-commerce regime, but: (1) the 0.15 Regime Simplificado coefficient for trade is one of the most favourable in the EU; (2) Madeira IRC 14.7% + CINM further reductions for qualifying activities; (3) NHR closed to new entrants 2024 but the IFICI replacement offers 20% flat IRS to certain skilled workers; (4) Portugal participates in EU OSS and IOSS for cross-border B2C VAT.
