  New Zealand Taxation

A flat 28% company rate keeps the income tax simple; GST (15%) and payday filing are the recurring cadence we manage.

What we file & when

Key New Zealand filings.

Income tax return (IR4)Standard due dates apply, with extensions commonly available through tax agents.
GST returnsMonthly, two-monthly or six-monthly depending on turnover.
PAYE filingsPayday filing with each payroll run.
Companies Office annual returnFiled annually to keep the company in good standing.

Typical deadlines under standard rules — actual dates shift with extensions, agent arrangements and entity type. We confirm your exact filing calendar at engagement.

Full tax scope

Everything under taxation.

The complete list — individual returns, corporate returns, registrations, indirect tax and disputes — delivered for New Zealand through the IRD.

Individual income tax returns

Personal tax returns for residents, non-residents and expats — employment, business, rental, investment and foreign income, filed correctly in each country you touch.

Corporate & company tax returns

Preparation and filing of company income tax returns — C-corps, limited companies, subsidiaries and branches — with workpapers that survive review.

Tax registrations

Getting you correctly registered wherever an obligation exists: federal and state registrations, VAT/GST numbers, employer accounts and e-filing portals.

Cross-border structuring & planning

Designing how your entities, contracts and cash flows sit across countries so you pay what the law requires — and not more.

Transfer pricing documentation

The intercompany pricing files (local file, master file, benchmarking) tax authorities demand when related companies trade with each other across borders.

Economic nexus & US state taxes

Working out where your sales or presence have quietly created a US state obligation — income, franchise and sales tax — then registering and filing where it matters.

Indirect tax — VAT / GST / sales tax

Registration, periodic returns and advisory for VAT, GST and sales-tax regimes in every market we cover.

Withholding tax & treaty relief

Getting cross-border payments (dividends, royalties, service fees) taxed at the correct treaty rate instead of the default — with the certificates to prove it.

Tax residency & permanent establishment

Advice on where you and your company are actually taxable — residency tests, PE risk from remote teams, and how to structure around both.

Expat & remote-founder tax

Coordinated home-and-host-country filings for founders and professionals living outside their passport country.

Advance / estimated tax computations

Quarterly and advance tax estimates so instalments are right-sized — no penalties, no interest-free loans to the government.

Tax notices, audits & disputes

Responses to authority notices, audit representation and appeals — measured where compliance is the answer, firm where the demand is wrong.

Tax due diligence

The tax workstream of a deal: exposures quantified, positions reviewed, and warranties negotiated with real numbers behind them.

Group tax reporting & deferred tax

Current and deferred tax provisions for financial statements, prepared to audit standard alongside our accounting advisory team.

How remote engagement works

Fully remote, with agent-linked filing arrangements for extended deadlines where available.

Pricing approach

Fixed annual fee; combined AU+NZ scopes are common and priced as one.

Questions

New Zealand tax — your questions

What company rate applies? +
New Zealand applies a flat company rate — it's modelled in the estimator and confirmed against IRD guidance during engagements.
Can you fix a GST backlog? +
Yes — backlog returns are prepared as a clean-up project, then the routine takes over.
