UAB vs MB in Lithuania: Which Business Entity Is Right for You? (2026 Guide)
5 Key Factors
- UAB (uždaroji akcinė bendrovė) is a private limited liability company – the most versatile corporate form in Lithuania. It uses a share-based ownership model with a minimum share capital of EUR 1,000 and allows both individual and corporate shareholders, making it suitable for international structures, regulated activities, and scalable business models.
- MB (mažoji bendrija) is a small partnership with limited liability, restricted to natural persons as members (maximum ten). MB has no mandatory share capital, which makes it attractive for simple, founder-driven projects – but limits its use for investment, licensing, and cross-border structures.
- The choice between UAB and MB affects ownership flexibility, investor readiness, management structure, taxation of distributions, licensing eligibility, and perception by banks and counterparties – not just registration costs.
- For non-residents, UAB is almost always the more practical option – particularly when the ownership chain involves foreign legal entities, regulated services, or future investment and restructuring.
- Company in Lithuania UAB (company code 304377400) helps non-residents choose the right business form, register a UAB or MB, and provides accounting, tax registration, and licensing support.
Choosing the right legal form is one of the most consequential decisions when starting a business in Lithuania. For foreign entrepreneurs, this decision shapes the company’s ownership flexibility, management model, tax treatment, and capacity for growth. A wrong choice at the incorporation stage can create structural limitations that are costly and time-consuming to resolve later.
In practice, two forms dominate the conversation: UAB and MB. Both provide limited liability, both are used by thousands of businesses, and both are available to foreign founders. Yet they differ in ways that matter enormously – especially for non-residents planning to operate across borders, attract investors, or engage in regulated activities. This article provides a detailed comparison of UAB and MB in 2026 as a practical decision-making guide for founders who need clarity, not just legal definitions.
Why Choosing the Right Legal Form in Lithuania Matters
The legal form determines who can own the company, how it is managed, how profits are distributed and taxed, whether investors and regulators find the structure credible, and whether the company can obtain licences. Choosing between UAB and MB without understanding these implications can result in a structure that limits the business within months – requiring costly reorganisation.
What Is a UAB in Lithuania?
UAB – uždaroji akcinė bendrovė – is a Lithuanian private limited liability company and the most widely used corporate form in the country. Shareholders hold shares proportional to their capital contribution, and the company is managed by a director appointed by the shareholders. The minimum share capital is EUR 1,000, part of which must be contributed before registration.
UAB allows both individual and corporate shareholders with no restrictions on nationality or residency. It supports multiple shareholders, corporate ownership chains, and subsequent restructuring – including investor rounds, share transfers, and subsidiary creation. This makes UAB the standard choice for trade, services, IT, logistics, fintech, and regulated projects.
What Is an MB in Lithuania?
MB – mažoji bendrija – is a small partnership. It is a separate legal entity with limited liability, but members can only be natural persons (maximum ten). There is no mandatory share capital. Ownership is based on membership interests rather than shares, and governance is simpler and less formalised than in a UAB. MB is designed for small, founder-driven businesses where all participants are individuals.
UAB vs MB: The Core Legal Differences
Both forms provide limited liability, but diverge significantly beyond that. UAB allows individual and corporate shareholders with no cap on numbers; MB restricts membership to natural persons only (maximum ten) – making it unsuitable for international holding structures or corporate joint ventures.
UAB requires EUR 1,000 in share capital, formalised through shares – providing a standardised mechanism for valuing and transferring ownership. MB has no capital requirement and no share-based model, which limits options when the business grows or new participants join.
UAB uses director-led governance recognised by banks and regulators. MB governance is flexible but can create ambiguity with external parties. For regulated activities – fintech, transport, gambling – UAB is typically the only form that satisfies licensing requirements.
Ownership: Shareholders in UAB vs Members in MB
In a UAB, ownership is structured through shares that can be transferred, diluted, or restructured through standard corporate mechanisms. In an MB, ownership is structured through membership interests held by natural persons only.
If the business anticipates corporate shareholders, an international holding structure, or future investors, UAB is the appropriate form. MB’s restriction to natural persons makes it structurally incompatible with most international and investment-oriented arrangements.
Capital Requirements: Does MB Really Have an Advantage?
MB’s lack of a mandatory share capital is often cited as its primary advantage. And on the surface, it is a real difference: establishing an MB does not require the founder to contribute EUR 1,000 to an accumulation account before registration.
However, in practice, EUR 1,000 is a modest amount, and formal share capital in a UAB serves important purposes: it signals financial commitment to banks, satisfies minimum capital requirements for licences, provides a clear basis for ownership valuation and transfer, and supports investor confidence. For non-residents, the absence of capital in an MB does not simplify banking onboarding – KYC procedures remain, and the lack of formal capital can actually raise questions during due diligence.
Management Structure: Director, Members and Operational Control
A UAB is managed by a director with formal authority to represent the company and manage operations – a structure familiar to banks, regulators, and international counterparties. An MB can be managed by its members directly or by a designated head, with less formalised governance that provides flexibility for small teams but can create ambiguity externally.
Taxation of UAB and MB in 2026
Both UAB and MB are subject to Lithuanian corporate income tax at the same basic rates: the standard rate is 15 percent, with a reduced rate of 5 percent for qualifying small companies. Practical differences arise at the level of distributions: UAB pays dividends subject to personal income tax, while MB member payouts may be classified differently – with varying personal tax implications.
Choosing MB solely for perceived tax savings, without professional analysis of the full picture – corporate form, payout structure, and personal tax residency – is one of the most common mistakes.
Which Structure Is Better for a Foreigner?
For non-residents, UAB is almost always more practical. The reasons are structural, not preferential. Many foreign founders use a corporate ownership chain – a parent company in another jurisdiction holding shares in the Lithuanian entity – which MB cannot accommodate due to its restriction on corporate members. UAB’s share-based structure provides an internationally recognised framework for ownership, transfer, and restructuring – essential for cross-border operations.
For B2B services, partnerships, regulated activities, or EU market access, UAB offers the governance and credibility that banks, regulators, and international counterparties expect. MB can work for a non-resident individual founder with a simple, local business model and no plans for corporate ownership or investment. But in most international scenarios, its structural limitations outweigh its simplicity.
Which Structure Is Better for a Small Local Business?
For a small, locally focused business with individual founders, no outside investors, and no licensing needs, MB can be a practical choice. Typical examples include freelancers, small service businesses, and founder-led projects. The important nuance: this assessment should be forward-looking. If there is any realistic possibility the business will outgrow the MB framework, starting with a UAB avoids later conversion costs.
UAB vs MB for Investment, Scaling and Licensing
Investors – whether angel investors, venture capital funds, or strategic partners – expect a share-based corporate structure. They need the ability to acquire shares, negotiate shareholder agreements, participate in governance, and eventually exit through a share sale. UAB provides all of this; MB does not.
Scaling across borders requires a structure that supports subsidiaries and multi-jurisdictional compliance – UAB’s flexibility serves this purpose well, while MB’s restrictions create friction at every stage. Lithuanian regulatory authorities for fintech, transport, and gambling require corporate form and capital criteria that only UAB can satisfy.
When MB Stops Being Convenient
There are several practical trigger points at which the initial simplicity of MB becomes a constraint. The business needs a corporate shareholder – for example, a foreign parent company or a holding entity. An investor wants to acquire an ownership stake through a recognised corporate mechanism. The number of members approaches or exceeds ten. The business requires a licence or permit mandating a specific corporate form or minimum capital. Banks or counterparties request a more formal corporate structure during onboarding. Or management complexity outgrows the MB governance model.
At any of these points, restructuring from MB to UAB incurs costs and administrative burden that often exceed the initial savings realised by choosing MB in the first place.
When UAB May Be Unnecessarily Heavy
If the project is genuinely small – a single founder, a local service business, no investment or licensing needs, and no corporate ownership – the EUR 1,000 capital requirement, accumulation account, and structured governance of a UAB may be more than the situation requires. For founders who simply want to formalise a small activity with minimal complexity, MB can be the right fit – provided its limitations are understood.
UAB vs MB: Practical Decision Framework
If all owners are natural persons, total members will remain under ten, no external investment is planned, the activity does not require licensing, and the business will stay small and local – MB is a reasonable option.
If any owner is a legal entity, if the business may attract investors, if the activity requires a licence, if the company will operate across borders, or if formal corporate structure matters for banking and counterparty relationships – UAB is the appropriate choice. In cases of doubt, UAB is the safer default.
Common Mistakes When Choosing Between UAB and MB
The most frequent errors include choosing MB solely because it has no capital requirement – without considering implications for banking and licensing. Failing to account for the restriction on corporate members, which blocks international ownership structures. Underestimating future investment needs and discovering MB cannot accommodate a share-based round. Confusing tax efficiency with corporate suitability. And creating a UAB without genuine need, incurring unnecessary complexity for a simple project.
How to Choose the Right Entity for Your Business in Lithuania
The decision should be guided by five questions: Who owns the business – individuals only, or also legal entities? How will profits be distributed? Is outside investment expected? Is the planned activity regulated? Is the company meant to remain small, or to scale across the EU? Answering these with clarity – ideally with professional guidance – leads to the right choice in the vast majority of cases.
