Netherlands BV vs Sole Proprietor: Which Structure to Choose (2025)

Accounting › Country Tax Guides › Netherlands Tax

Choosing between a sole proprietorship and a BV is one of the most important decisions for entrepreneurs in the Netherlands. This guide compares the two main structures — their taxation, liability, costs, and the profit level at which a BV becomes advantageous — along with partnerships and the role of limited liability, helping you understand the tax and legal trade-offs of each Dutch business structure.

What is a sole proprietorship (eenmanszaak / ZZP)?

A sole proprietorship (eenmanszaak), often called ZZP (zelfstandige zonder personeel) for solo self-employed people, is the simplest structure: the business is tied directly to the owner, with no legal separation. It’s set up easily by registering with the Chamber of Commerce (KVK), needs no minimum capital, and the profit is taxed on the owner’s personal income tax return in Box 1. The owner can claim valuable deductions but is personally liable for the business’s debts.

This structure suits most starting entrepreneurs and freelancers due to its simplicity, low cost, and tax deductions in the early years. The main drawback is unlimited personal liability. Understanding the sole proprietorship — simple, Box 1 taxed, with deductions but personal liability — is the starting point for most entrepreneurs, as it’s the default and often most advantageous structure when profits are modest.

What is a BV (private limited company)?

A BV (besloten vennootschap) is a private limited company — a separate legal entity with limited liability, so the owner’s personal assets are generally protected from business debts. It’s set up via a notarial deed (with minimal required capital, EUR 0.01, though more is advisable) and registered at the KVK. The BV pays corporate tax on its profit; the owner-director (DGA) draws a salary (taxed in Box 1) and can receive dividends (taxed in Box 2). The BV also enables the 30% ruling for eligible expats.

The BV offers limited liability and tax-planning flexibility (deferring dividends, retaining profits) but has higher setup and running costs (notary, annual accounts, payroll). It suits higher-profit or higher-risk businesses. Understanding the BV — a separate entity with limited liability, taxed via corporate tax plus Box 2 — is essential for entrepreneurs considering incorporation, as it changes both the tax treatment and the liability position fundamentally.

How does the tax compare?

For a sole proprietorship, profit is taxed in Box 1 at progressive rates (up to 49.50%), but reduced by the self-employed deduction, SME profit exemption (12.7%), and (for new businesses) the starter’s deduction — making the effective rate lower, especially at modest profits. For a BV, profit is taxed at corporate rates (19%/25.8%), then dividends at Box 2 (24.5%/31%), with the DGA’s salary taxed in Box 1. At higher profits, the BV’s combined rate can be lower, especially with profit retention.

So at lower profits, the sole proprietorship’s deductions make it more tax-efficient; at higher profits, the BV’s corporate-plus-Box-2 structure (with deferral) tends to win. The crossover depends on the specifics. Understanding how the tax compares — deductions favoring the sole proprietorship at low profit, the BV structure at high profit — is central to choosing the right structure for your profit level and plans.

Where is the turning point?

The ‘turning point’ — where a BV becomes more tax-efficient than a sole proprietorship — is often cited at roughly EUR 150,000 of annual profit, though it varies with circumstances (the level of the DGA’s required salary, whether profits are reinvested or distributed, the 30% ruling, and business risk). Below the turning point, the sole proprietorship’s deductions usually make it cheaper; above it, the BV’s structure tends to be more efficient, particularly if profits are retained.

So the profit level is a key factor, with around EUR 150,000 a common (but circumstance-dependent) guide. Liability and the 30% ruling also influence the choice beyond pure tax. Understanding the turning point — roughly EUR 150,000, varying by situation — helps entrepreneurs gauge when incorporating into a BV becomes worthwhile, though a detailed calculation for the specific situation is recommended before deciding.

What about partnerships and liability?

Other structures include the general partnership (VOF, vennootschap onder firma) for two or more partners, where each partner is taxed in Box 1 on their profit share (with the self-employed deductions) but bears personal liability, and the limited partnership (CV). The key liability distinction is that sole proprietorships and partnerships expose the owners personally, while the BV (and NV) limit liability to the company. This liability protection is a major non-tax reason to choose a BV, especially in higher-risk activities.

So the choice spans tax efficiency and liability: partnerships share the sole proprietorship’s tax treatment and personal liability, while incorporation (BV) brings limited liability. Understanding the partnership options and the liability distinction helps entrepreneurs — especially those with partners or in risky sectors — choose a structure that balances tax efficiency against the protection of limited liability, a crucial consideration alongside the tax comparison.

How does the 30% ruling affect the choice?

For eligible expats, the 30% ruling can tip the decision toward a BV. The ruling applies to employment income, so an expat entrepreneur employed by their own BV (drawing a salary) can benefit from the 30% tax-free allowance on that salary — a significant advantage unavailable to a sole proprietor (who has no employer/salary). So an eligible expat may favor a BV specifically to access the 30% ruling on their director’s salary, beyond the usual profit-based comparison.

This makes the BV more attractive for qualifying expat entrepreneurs than the profit turning point alone would suggest. The ruling’s benefit can outweigh the BV’s higher costs. Understanding how the 30% ruling affects the choice — favoring a BV for eligible expats — is important for international entrepreneurs, as accessing the ruling through their own BV can be a decisive factor beyond the standard tax comparison.

Can you convert between structures?

Yes — you can convert a sole proprietorship into a BV as your business grows (or, less commonly, a BV back to a sole proprietorship if profits decline). Converting a sole proprietorship with assets, goodwill, or capital gains into a BV can often be done with tax deferral (the ‘silent’ or ‘noisy’ conversion routes), avoiding immediate tax on built-up value. This lets entrepreneurs start simple and incorporate later when profits justify it, without a punitive tax cost.

So the structure isn’t permanent — conversion (especially sole proprietorship to BV) is common as businesses grow, often with tax deferral on the transfer of assets and goodwill. Professional advice ensures it’s done efficiently. Understanding that you can convert — typically to a BV as profits rise, with deferral — reassures entrepreneurs that starting as a sole proprietorship doesn’t lock them in, and they can incorporate when it becomes advantageous.

What are the ongoing obligations of a BV?

A BV has more ongoing obligations than a sole proprietorship: filing annual corporate tax returns; preparing and filing annual financial statements with the Chamber of Commerce (KVK); running payroll for the director’s salary (with wage tax filings); maintaining proper company administration; and the customary salary requirement for the DGA. These create higher administrative costs (often requiring an accountant). The sole proprietorship, by contrast, has lighter obligations — mainly the income tax return and VAT.

So the BV’s benefits come with greater administrative burden and cost, which must be weighed against its advantages. For smaller businesses, this overhead can outweigh the tax benefits. Understanding the BV’s ongoing obligations — corporate filings, annual accounts, payroll, and administration — helps entrepreneurs factor the higher running costs into their structure decision, alongside the tax and liability comparison.

How does limited liability actually work?

A BV’s limited liability means the company (a separate legal entity) is liable for its debts, not the shareholder personally — so your personal assets are generally protected if the business fails. However, this protection isn’t absolute: directors can be personally liable for mismanagement, fraud, unpaid taxes in cases of improper management, or if they’ve given personal guarantees (which banks often require for loans). So limited liability provides important but not unlimited protection.

So the BV shields personal assets in normal circumstances, but directors must act properly and may still face personal exposure via guarantees or misconduct. Understanding how limited liability actually works — protection with exceptions for guarantees and improper management — helps entrepreneurs appreciate the real (but not absolute) protection a BV offers, an important consideration for those in higher-risk businesses choosing their structure.

Common structure choice mistakes to avoid

Common mistakes include incorporating a BV too early (when a sole proprietorship’s deductions and lower costs would be better), staying a sole proprietorship too long (missing the BV’s advantages at higher profit), ignoring liability risk, overlooking the 30% ruling opportunity (for expats), and not getting a proper calculation before deciding. Each can cost money or leave the entrepreneur over- or under-protected.

Avoiding them means matching the structure to your profit and risk, considering the 30% ruling, and getting a tailored calculation. Because the choice has lasting tax and liability effects, care is essential. Understanding these common mistakes helps entrepreneurs choose and review their structure wisely, balancing tax efficiency, liability, and cost for their specific situation.

How to decide on your structure

Deciding between a sole proprietorship and a BV comes down to weighing profit level (the ~EUR 150,000 turning point), liability risk, the 30% ruling (for expats), administrative cost tolerance, and growth plans. A detailed calculation for your specific numbers is the best guide, and the decision can be revisited (converting later). Many entrepreneurs start simple as a sole proprietorship and incorporate when profits and risk justify it.

Because the right choice is situation-specific, getting a tailored comparison — ideally from a tax adviser — before deciding is worthwhile. Understanding how to decide — weighing profit, liability, the 30% ruling, and cost, with the option to convert — helps entrepreneurs choose the structure that best fits their current situation and plans, the foundation of their business tax position.
