Pregnancy and maternity leave for freelancers in the Netherlands (ZEZ, 2026)

What is the ZEZ maternity benefit for freelancers in the Netherlands in 2026?

In 2026, a self-employed freelancer in the Netherlands can claim the Self-Employed and Pregnant benefit (Zelfstandige en Zwanger, ZEZ) for at least 16 weeks. The ZEZ period starts 6 to 4 weeks before the day after the expected due date and always includes at least 10 weeks after birth. If 1,225 hours were worked in the prior year, the maximum benefit applies (linked to the statutory minimum wage).

Browse the [Knowledge Hub](/knowledge-hub) for more freelancer accounting guides. The ZEZ benefit is available to self-employed people and also to certain self-employed professionals (for example, freelancers and artists). Planning the leave period early reduces the risk of missed client deadlines and missed tax filings during the 16-week window.

The maximum ZEZ benefit is tied to the statutory minimum wage. As of 1 January 2026, the statutory minimum wage for age 21+ is €14.71 per hour. Use the [VAT returns guide for freelancers](/knowledge-hub/vat-returns-netherlands-expat-freelancer-guide) to schedule BTW-aangifte (VAT return) dates around the start of the benefit period, and use the [deductible business expenses overview](/knowledge-hub/deductible-expenses-freelancers-netherlands) when budgeting for temporary replacement costs.

• Minimum duration: 16 weeks (including at least 10 weeks after birth).
• Start window: 6 to 4 weeks before the day after the expected due date.
• Eligibility includes freelancers and other self-employed professionals.
• Maximum amount applies if prior-year hours are at least 1,225 hours.
• Maximum benefit level is linked to the statutory minimum wage.

When should a freelancer apply for the ZEZ benefit, and what documents are needed?

The ZEZ benefit can start 6 to 4 weeks before the day after the expected due date, and the application must be submitted no later than 2 weeks before the chosen start date. Submit a pregnancy statement from a doctor or midwife with the application; copies of income tax assessments may be requested to set the amount. This matters because late applications can postpone payments.

Choose a start date inside the 6 to 4 week window before the day after the expected due date, then count back 2 weeks to set the latest safe application date. Put the deadline in the same calendar as client handovers and invoice runs. If the start date overlaps a VAT period end, plan the BTW-aangifte (VAT return) workflow before the leave starts.

Prepare the supporting documents before submitting the application. Store a scan of the pregnancy statement and keep recent tax documents available in the same folder. A complete file reduces follow-up requests and speeds up confirmation of the benefit amount when prior-year profit is used. After submitting, keep the confirmation message as proof of the submission date.

• Pick a start date within the 6 to 4 week pre-due-date window.
• Submit the application no later than 2 weeks before the chosen start date.
• Attach a pregnancy statement (zwangerschapsverklaring) from a doctor or midwife.
• Prepare copies of income tax assessments if they are requested.
• Confirm the plan keeps at least 10 weeks after birth covered.
• Save proof of the submission date to show the deadline was met.

How is the ZEZ amount calculated, and how does the 1,225-hour rule work?

The ZEZ amount depends on prior-year activity. If at least 1,225 hours were worked as a self-employed person in the calendar year before the benefit starts, the maximum amount applies and is set at the statutory minimum wage level. If fewer than 1,225 hours were worked, the ZEZ amount is lower and depends on the profit in that prior year. This matters because the hour total changes the benefit ceiling.

Use prior-year time tracking, invoices, and project logs to estimate the 1,225-hour total before applying. 1,225 hours is about 23.6 hours per week across a 52-week year, so part-time freelancing may fall below the maximum threshold. When the hour total is below 1,225, keeping the income tax return and profit calculation clean helps speed up benefit calculations.

How does a ZEZ benefit affect income tax (income tax return and provisional assessment) in 2026?

A ZEZ benefit does not belong in business profit for income tax. The benefit does not have to be reported as profit from the business, and a pregnancy benefit from a public institution is reported as wage income instead. Premiums paid for a pregnancy-related insurance benefit are not deductible as business costs. This matters because wage income can change the final income tax and social insurance calculation for 2026.

If expected 2026 income drops during maternity leave, update the provisional income tax assessment (voorlopige aanslag) so monthly payments match the new estimate. The online change flow for the 2026 provisional assessment is done in Mijn Belastingdienst and is based on 2024 data when the assessment was not changed earlier. After submitting a change, the response is usually received within 4 to 5 weeks and always within 8 weeks.

Keep the income categorisation consistent: business profit stays in the profit section, while the ZEZ benefit is treated as wage income. This separation avoids errors in the profit calculation and supports a clean year-end income tax return. If a partner also has income, update the estimate so combined tax withholding aligns with the expected 2026 outcome.

• Record ZEZ as wage income, not as business profit.
• Do not deduct pregnancy-insurance premiums as business expenses.
• Check whether 2026 income differs from the 2024-based provisional assessment.
• Submit a provisional assessment change early if monthly payments are off by more than 1 month of cash flow.
• Keep the confirmation that the change request was submitted (date-stamped).
• Recheck the provisional assessment after 4 to 5 weeks, and follow up if no decision arrives within 8 weeks.

What VAT (BTW) deadlines should you plan around maternity leave, and what happens if you miss them?

VAT returns (BTW-aangifte) and VAT payments have deadlines even during maternity leave. For quarterly filers in 2026, deadlines include 30 April 2026 (Q1) and 31 July 2026 (Q2). The tax administration applies a 7-day grace period after the filing due date and after the payment due date. This matters because missing the grace period can trigger an €82 late-filing fine and a 3% late-payment fine (minimum €50, maximum €6,709).

Use the due-date calendar to pick a ZEZ start date that avoids the last week before a VAT deadline when possible. If a deadline falls inside the leave period, prepare the VAT return in advance or arrange a delegate to submit it. If payment is late, the late-payment fine is calculated as a percentage of the unpaid amount and can rise to 10% for frequent late payments, but the annual cap stays €6,709. Keep proof of submission and proof of payment in the bookkeeping file.
