November 27, 2025Tax Guide: Contractors and Schedular Payments in New Zealand
Understanding the tax obligations for contractors in New Zealand can be complex, particularly when it comes to schedular payments and withholding tax requirements. This comprehensive guide breaks down everything contractors, labour-hire firms, and businesses need to know about the schedular payments regime.
What Are Schedular Payments?
Schedular payments are specific types of payments received by contractors that are subject to the schedular payments regime under New Zealand tax law. This system determines how much tax is deducted from contractors’ earnings at the source, known as withholding tax, rather than paying all tax obligations at year-end.
The schedular payments regime provides a structured approach to tax collection that benefits both contractors and the tax system by ensuring regular tax payments throughout the year.
Key Features of the Schedular Payments System
Three Important Points to Remember:
- Rate Election: Contractors subject to the schedular payments regime can choose their own withholding tax rate instead of accepting the default rate prescribed by Schedule 4 of the Income Tax Act 2007
- Opt-in Provision: Even if you’re not automatically covered by the regime, you can voluntarily enter it with your payer’s agreement
- Labour-hire Requirements: All payments from labour-hire firms are automatically subject to withholding tax requirements
Choosing Your Withholding Tax Rate
The IR330C Form Process
All contractors have the flexibility to select their preferred withholding tax rate within prescribed limits. To exercise this choice, you must complete a Tax rate notification for contractors (IR330C) form in the following situations:
- Starting a new contracting position
- Wanting to change your current tax rate
- Moving between different contracting arrangements
Minimum Withholding Tax Rate Requirements
The minimum withholding tax rates are:
- Standard contractors: 10%
- Non-residents and temporary work visa holders: 15%
Getting Help with Rate Selection
If you’re uncertain about which withholding tax rate to choose, Inland Revenue provides an estimation tool to help determine the most appropriate tax rate based on your expected annual income and circumstances.
Consequences of Not Selecting a Rate
Failing to complete the IR330C form triggers the “no-notification rate,” which is significantly higher than standard rates:
- General contractors: 45% withholding tax rate
- Non-resident contractor companies: 20% withholding tax rate
These elevated rates are designed to encourage proper tax rate selection and ensure adequate tax collection.
Prescribed Withholding Rates
Inland Revenue may impose a prescribed withholding rate for contractors who haven’t met their tax obligations. This intervention helps contractors manage their tax liabilities and eliminate accumulated tax debt. The prescribed rate may include both schedular tax and additional percentages set by Inland Revenue.
Labour-Hire Contractors: Special Considerations
Mandatory Withholding Tax
Labour-hire contractors face stricter requirements:
- Withholding tax is mandatory, even for contractors operating through their own companies
- The standard rate is 20% if no rate is selected
- These rules apply regardless of the contractor’s business structure
What Constitutes a Labour-Hire Firm?
The definition of “labour-hire firm” is deliberately broad and includes:
- Recruitment agencies
- On-hire companies
- Any entity where arranging labour hire is a main business activity
- Businesses that arrange for contractors to work directly for their clients
This encompasses various contractor types, including:
- IT contractors
- Consulting services
- Advisory services
- Specialized professional services
Obligations for Labour-Hire Firms
Labour-hire firms must:
- Deduct withholding tax from all contractor payments
- Include payment and deduction details in employment information
- Submit this information through payday filing
- Maintain proper records of all transactions
Certificates of Exemption and Special Arrangements
Standard Certificates of Exemption from Withholding Tax
Some contractors can apply for certificates of exemption, allowing them to:
- Skip withholding tax deductions
- Pay all tax obligations at year-end
- Manage their cash flow more effectively
Restrictions for Labour-Hire Contractors
Important limitation: New Zealand contractors working for labour-hire firms cannot obtain certificates of exemption. This restriction ensures consistent tax collection in the labour-hire sector.
Special Tax Rates and Codes
When standard withholding rates don’t suit your business circumstances, you can apply for special tax rates by completing a Special tax code application (IR23BS). This flexibility extends to:
- Reduced rates for specific situations
- Zero percent (0%) rates where justified
- Customized arrangements for unique circumstances
Recording Requirements for Special Rates
Even when special tax codes result in 0% withholding rates, labour-hire firms must still record all payment details in their employment information submissions through payday filing.
Non-Resident Contractors
Special Provisions
Non-resident contractors working for labour-hire firms have unique options:
- May apply for certificates of exemption (unlike resident contractors)
- Subject to minimum 15% withholding rate
- Same 15% minimum applies to temporary work visa holders
Universal Application
The 15% minimum withholding rate applies to all non-resident contractors, not just those working through labour-hire firms.
Employees vs. Contractors in Labour-Hire Companies
Different Rules Apply
It’s crucial to distinguish between:
- Contractors: Subject to schedular payment rules (IR330C form)
- Employees: Follow standard employment tax rules (IR330 form)
Employees receiving salaries or wages from labour-hire companies follow the same tax rules as employees in any other business.
Voluntary Withholding Agreements
Opting Into the System
Contractors not automatically covered by schedular payment rules can voluntarily enter the system through written agreements with their payers.
Documentation Requirements
Voluntary withholding agreements can take various forms:
- Formal contracts
- Email correspondence
- Written memoranda
- Letters of agreement
The key requirement is sufficient evidence of mutual agreement to deduct withholding tax.
Process and Benefits
Once a voluntary withholding agreement is established:
- The contractor completes an IR330C form
- The payer must withhold tax at the selected rate
- Standard schedular payment rules apply
- Both parties gain certainty about tax obligations
Fringe Benefit Tax Exclusion
An important advantage of voluntary withholding agreements is that fringe benefit tax (FBT) doesn’t apply to benefits provided to contractors under these arrangements. This occurs because voluntary withholding agreements exclude the parties from the employer-employee definition for FBT purposes.

Conclusion – Schedular Payments
The schedular payments regime provides a structured framework for managing contractor tax obligations in New Zealand. While the system offers flexibility through rate selection and voluntary agreements, it also imposes strict requirements, particularly for labour-hire arrangements.
Success in navigating this system requires understanding your specific situation, completing appropriate paperwork, and maintaining compliance with ongoing obligations. Whether you’re a contractor, labour-hire firm, or business engaging contractors, proper implementation of these rules ensures smooth operations and tax compliance.
Regular review of your arrangements, staying current with tax obligations, and seeking professional advice from Business Like NZ Ltd when needed will help optimize your position within the schedular payments framework while meeting all legal requirements.
