Dutch Tax & Accounting FAQ

Katashov Tax helps individuals, expats and entrepreneurs in the Netherlands with P-form, M-form and C-form income tax returns, ZZP annual reporting, VAT/BTW and ICP returns, KOR, benefits/toeslagen, world income declarations, Box 3/actual return questions and tax consultations on employee, ZZP, BV and DGA structures.

You may need to file a Dutch income tax return if you receive an invitation from the Tax Administration, expect a refund, had more than one source of income, owned a home, had business income, foreign income, Box 3 assets, or moved to or from the Netherlands during the tax year. In some cases it is useful or required to file even without an invitation.

The P-form is generally used by Dutch tax residents for a full tax year. The M-form is used for the year of immigration or emigration, when you lived in the Netherlands for only part of the year. The C-form is used by non-resident taxpayers who lived outside the Netherlands for the entire year but had Dutch income or assets relevant for Dutch taxation.

You need an M-form for the tax year in which you immigrated to or emigrated from the Netherlands. The form separates resident and non-resident periods and may include foreign income, deductions, mortgage information, Box 3 assets, 30% ruling questions and other cross-border elements. A small mistake can materially change the final assessment.

A C-form may be required if you lived outside the Netherlands for the full tax year but had Dutch-source income, pension, property, a second home or another connection with the Dutch tax system. The key question is which income is taxable in the Netherlands and whether deductions or qualifying non-resident taxpayer rules may apply.

ZZP or eenmanszaak income is usually taxed in Box 1 as business profit. The calculation may include business expenses, entrepreneur deductions, MKB-winstvrijstelling, startersaftrek, the 1,225-hour criterion, tax credits and the Zvw contribution. This means the effective tax rate for ZZP can differ from an employee with the same gross amount. For investment, KIA and depreciation scenarios, use the ZZP tax optimization calculator.

In general, business expenses must be connected with generating income. Common examples include professional software, equipment, bookkeeping, training, business phone and internet usage, marketing, business travel, bank fees and part of work-related costs. It is important to keep invoices and separate business costs from private spending. If the costs relate to business assets or investments, check the annual effect in the ZZP tax optimization calculator.

Most VAT-registered entrepreneurs file VAT returns quarterly, although monthly or annual filing can apply in some cases. Even if there was no turnover in a period, a VAT return may still have to be submitted. If you sell goods or services to EU business clients, an ICP declaration may also be required.

KOR is the Dutch small businesses VAT exemption. It can be useful when your annual turnover is below the applicable threshold and your clients do not need to deduct VAT. Under KOR you generally do not charge VAT to clients and you cannot deduct VAT on business expenses and investments, so the decision should be calculated before applying.

A BV may become attractive when profit is high, business risks increase, you plan to hire staff, keep profit inside the company, attract investors or create a more corporate structure. However, a BV also brings additional accounting, annual reporting, corporate tax, DGA salary and Box 2 dividend taxation. The right decision depends on taxes, risk, cash flow and the owner’s plans. For a first comparison of employee, ZZP and BV outcomes, use the effective tax rate calculator.

If you own and work for a Dutch BV, you are often considered a DGA and may need to pay yourself a customary salary, known as gebruikelijk loon. Salary is taxed in Box 1, while profit remaining in the BV after corporate income tax can be distributed as dividends and taxed in Box 2. The mix of salary, dividends and retained earnings affects your effective tax rate.

You can use our effective tax rate Netherlands calculator to compare employee salary, ZZP profit, ZZP starter deductions and BV + DGA taxation. The model includes Box 1, tax credits, Zvw, corporate income tax, Box 2 and investment deductions. It is a planning tool, not a substitute for personalised advice.

The 30% ruling, now often referred to as the expat scheme, allows an employer to pay part of a qualifying foreign employee’s salary as a tax-free allowance for extraterritorial costs. Typical conditions include employment, recruitment from abroad, specific expertise, distance from the Dutch border before moving and a formal decision from the Tax Administration. Self-employed ZZP entrepreneurs cannot apply the 30% ruling to their own business profit. You can model the bruto-to-netto effect in the salary calculator.

Common benefits include zorgtoeslag, huurtoeslag, kinderopvangtoeslag and kindgebonden budget. Eligibility depends on income, household composition, age, residence status, rent, childcare costs and other factors. Incorrect applications may lead to repayments, so it is worth checking the estimate before applying.

A world income declaration may be requested when Dutch authorities need information about your income outside the Netherlands, for example for benefits, contributions or non-resident taxpayer status. The goal is to report foreign income correctly without mixing it up with income already taxed elsewhere.

Box 3 relates to savings, investments and certain assets. In some situations it is useful to review whether actual return information should be submitted through an OWR or actual return procedure, especially when the assumed return differs significantly from the real return. For a first check, use the OWR / actual return page; for larger portfolios, use the Box 3 vs BV calculator.

In many situations it is possible to file, amend or respond to assessments for previous years, but the options depend on the tax year, type of assessment and deadlines. If you have a voorlopige aanslag, definitieve aanslag or a letter from the Tax Administration, send it for review before taking action.

Typical documents include DigiD access or source data, annual salary statements, foreign income documents, mortgage statements, bank and investment balances, ZZP invoices and expenses, VAT reports, childcare invoices, rental agreement and letters from the Tax Administration. The exact list depends on your personal or business situation.

The usual process includes a short description of your situation, selection of the relevant service, a document checklist, preparation of the calculation or return, review of the result and filing or filing instructions. Complex cases usually start with a consultation to identify risks and possible options. If you have already used one of the tax tools, include your input values or result when contacting us.

The price depends on the type of tax return, number of income sources, business activity, foreign elements, Box 3 assets, correspondence with the Tax Administration and urgency. Basic prices are listed on the services page, while complex cases are quoted individually.
