Aruba. Most people think of beaches and casinos. I think of Dutch Caribbean tax pragmatism with a small-jurisdiction twist.
If you’re considering planting a business flag here—especially as a solo operator—you need to understand the Eenmanszaak, the local term for sole proprietorship. It’s straightforward. No corporate veil, no separate legal entity. Just you, your business income, and the tax authority watching closely.
Let me walk you through what this status actually looks like in 2026, the numbers you’ll face, and whether it makes sense for your situation.
What You’re Actually Registering
A sole proprietorship in Aruba is called an Eenmanszaak. It’s the simplest business structure available. You register with the Chamber of Commerce, you operate under your own name (or a trade name), and legally speaking, you and the business are one.
No corporate formalities. No board meetings with yourself.
But that also means unlimited liability. Your personal assets are on the line if things go south. I’ve seen too many optimistic entrepreneurs ignore this detail until a client dispute or supplier claim wipes them out. If asset protection matters to you—and it should—this structure is not your friend.
That said, for low-risk service businesses, digital nomads testing a market, or consultants who want to formalize income without bureaucratic overhead, it works.
The Tax Reality
Here’s where it gets interesting. As a sole proprietor, you’re taxed under Aruba’s Personal Income Tax regime (Inkomstenbelasting). Your business profits are treated as personal income.
The 2025 rates (still applicable in early 2026) are structured progressively:
| Taxable Income (AWG) | Tax Rate |
|---|---|
| 0 – 34,930 | 0% |
| 34,931 – 65,904 | 21% |
| 65,905 – 147,454 | 42% |
| Above 147,454 | 52% |
So the first Afl. 34,930 (approximately $19,450 USD) is tax-free. Not bad. If you’re running a lean operation or testing a side hustle, you might stay entirely within that bracket.
Once you cross into higher brackets, the rates climb fast. That 52% top rate kicks in above Afl. 147,454 (roughly $82,140 USD). For high earners, this is painful. You’ll want to explore deductions, expense optimization, or eventually consider a corporate structure if your income justifies it.
Social Security: The Hidden Bite
Taxes are only part of the picture. Aruba’s social security system adds another layer.
As a self-employed individual, you’re required to contribute:
- AOV/AWW (Old Age and Widow’s Pension): 13.5%
- AZV (Health Insurance): 10.5%
That’s a combined 24% on top of your income tax. These aren’t calculated on gross revenue—they’re based on your taxable income. But still, when you add a 42% income tax bracket and 24% social contributions, you’re looking at a combined marginal rate of 66%.
Let that sink in.
This is why understanding your bracket and planning deductions becomes critical. Every legitimate business expense you can document reduces both your tax and social security burden.
The Small Business Scheme (KOR)
Now for the good news. Aruba offers a Kleineondernemersregeling (KOR), or Small Business Scheme, which exempts you from turnover tax if your annual revenue stays below Afl. 50,000 (around $27,850 USD).
Turnover tax in Aruba is set at 7% on gross sales. For micro-businesses, this exemption is significant. If you’re a freelance designer, remote consultant, or small-scale service provider, staying under that threshold means you avoid the administrative hassle of turnover tax filings and the tax itself.
But here’s the trade-off: you can’t reclaim turnover tax on your business expenses. If you’re buying expensive equipment or have significant input costs, you might actually be better off not using the KOR and staying in the regular regime. Do the math for your specific situation.
Who This Works For
The Eenmanszaak makes sense if:
- You’re testing a business idea without committing to corporate overhead.
- Your income is modest and stays within lower tax brackets.
- You’re a digital service provider with minimal liability exposure.
- You value simplicity over asset protection.
It does not make sense if:
- You’re handling significant capital or high-risk contracts.
- You’re earning well into the higher tax brackets and could benefit from corporate tax planning.
- You need to separate personal and business liability for legal protection.
- You plan to scale and eventually bring in partners or investors.
Registration Process
Setting up is relatively painless. You’ll register with the Aruba Chamber of Commerce. Expect to provide identification, proof of address, and details about your business activity. Fees are modest compared to corporate registration.
You’ll also need to register with the tax office (Impuesto) for income tax and, if applicable, turnover tax purposes. If you’re using the KOR exemption, make sure you indicate that during registration.
Processing times are typically short—Aruba’s bureaucracy is relatively efficient for a Caribbean jurisdiction. But don’t expect same-day service. Budget a week or two for everything to clear.
Record-Keeping and Compliance
You’re required to maintain proper books. This isn’t optional. Aruba’s tax authority can and will audit sole proprietors, especially if your declared income seems inconsistent with your lifestyle or industry norms.
Keep receipts. Track expenses. Use accounting software if you’re not spreadsheet-savvy. The deductions you can justify will directly reduce your taxable income—and your social security contributions.
Common deductible expenses include:
- Office rent or home office allocation (be reasonable with this)
- Equipment and software
- Professional services (legal, accounting)
- Marketing and advertising
- Travel related to business operations
Don’t get creative. Aggressive deductions invite scrutiny, and Aruba’s tax office has limited patience for borderline claims.
When to Consider Alternatives
If your income exceeds Afl. 100,000 ($55,700 USD) annually, you should at least model the numbers for an N.V. or B.V. (the local corporate structures). Corporate tax rates and planning opportunities may reduce your effective tax burden, especially once payroll optimization and retained earnings strategies come into play.
And if asset protection is non-negotiable—because you’re in a litigious industry or simply understand the value of separating personal wealth from business risk—then a sole proprietorship is the wrong vehicle from day one.
Final Thoughts
The Eenmanszaak in Aruba is a pragmatic choice for the right operator. It’s transparent, it’s simple, and it keeps you compliant without the overhead of corporate governance.
But it’s not a magic bullet. You’re still facing progressive income tax rates that climb steeply, plus mandatory social contributions that add up fast. If you’re earning modestly and staying under the KOR threshold, this structure gives you breathing room. If you’re scaling or earning into higher brackets, you’ll outgrow it quickly.
Run your numbers. Model your tax burden. And if you’re serious about long-term tax efficiency, treat this as a starting point, not a destination.
