Frequently Asked Questions
Can NZ business consultants claim client entertainment?
Entertainment expenses are 50% deductible in New Zealand. This includes client meals, drinks, and similar hospitality costs. Keep all receipts and record the business purpose and attendees.
Is professional indemnity insurance deductible for NZ business consultants?
Yes. Professional indemnity and public liability insurance protecting you from client claims is a fully deductible business expense. It is highly recommended for any consultant providing advice for a fee.
Can I claim the cost of an MBA or executive programme as professional development?
Only if the course directly maintains or improves skills used in your existing consulting practice. A general MBA for career advancement is less likely to be deductible. An executive programme on leadership or strategy relevant to your consulting work should qualify. Keep the course outline as evidence.
How do NZ business consultants determine their provisional tax instalments?
Most consultants use the standard uplift method: pay 105% of last year's residual income tax in three instalments. If your income is growing, the Accounting Income Method (AIM) lets you pay based on actual profit each period, which can reduce overpayment.
