NZ Tax Guide for Software Developers (2025-26)
Software developers in New Zealand may be employed (PAYE) or work as contractors or freelancers (schedular payments or GST-registered self-employment).

Key Deductions for Software Developers in NZ
Home office expenses (contractors)
Contractors working from home can deduct a proportion of rent or mortgage interest, electricity, and internet based on the floor area and time used for work.
Computer hardware and software
Equipment, software licences, and subscriptions purchased for work purposes are deductible. Items over $1,000 may need to be depreciated rather than expensed immediately.
Professional memberships and training
Membership fees for organisations like NZCS or AWS certifications required for your work role may be deductible.
Internet and phone costs
The work-use proportion of your internet and mobile plan is deductible for contractors or employees claiming unreimbursed work expenses.
Deductibility depends on individual circumstances. Consult a registered tax agent or accountant for personalised advice. See IRD guidance on individual expenses.
Frequently Asked Questions
How are software contractor rates taxed in NZ?
IT contractors not using a company structure are typically subject to schedular payment withholding tax at 20%. If you are GST-registered and earning over $60,000 annually from contracting, you must also charge 15% GST on your services.
Do software developers need to pay provisional tax?
If your residual income tax from contracting or self-employment exceeds $5,000 in a year, you must pay provisional tax in installments during the following year. IRD's standard uplift method adds 5% to your previous year's residual income tax.
Can I use a company structure to reduce my tax as a developer?
Operating through a company (Ltd) is taxed at 28% on business profits instead of up to 39% for individuals. However, salary you pay yourself from the company is still subject to PAYE. Seek advice from an accountant before choosing a structure.
What is the difference between being employed and contracting for a developer?
As an employee you pay PAYE on a salary and your employer manages ACC and KiwiSaver. As a contractor you typically earn a higher day rate but must manage your own tax, ACC levies (which are higher for the self-employed), and KiwiSaver is voluntary.
