Sole trader / contractor on $50,000
On $50,000 trading profit (2026/27), a sole trader models about $41,987.00 cash take-home after income tax $7,138.00 and ACC earner levy $875.00 — with NZ$0 employer KiwiSaver (package = take-home).
Key takeaways
- Sole trader / contractor: ≈ $41,987.00 cash take-home on $50,000 (tax + ACC earner levy ≈ $8,013.00; package ≈ $41,987.00).
- Rank #2 of 2 on $50,000 (highest package first; cash take-home ties).
- Employer KiwiSaver is NZ$0 on this path — you must self-fund retirement savings (IRD employer KiwiSaver rules apply to employers of employees, not to your own trading profit).
- Usually settle income tax and ACC earner levy via your income tax return; provisional tax may apply when residual income tax exceeds the IRD threshold (educational three-instalment hint).
- Compare with: Employee.

Official rules for this path
ACC earner levy
- 1.75% of liable earnings up to $156,641
- Max annual earner levy $2,741.22 in this engine
- ACC work levy by industry is not modelled on this hub
Employer KiwiSaver (3.5%)
- Compulsory employer contribution (CEC) 3.5% from 1 Apr 2026 for eligible contributing members
- IRD: CEC applies when the employee is in KiwiSaver (or a complying fund) and KiwiSaver is deducted from salary or wages — not when opted out
- Paid into KiwiSaver — not modelled as a cash deduction from take-home here; ESCT on employer contributions is excluded
- Sole traders receive NZ$0 employer KiwiSaver on their own trading profit in this comparison
KiwiSaver contribution rates
- Employee contribution rates are chosen (or default when enrolled) — from 1 Apr 2026 the default minimum is 3.5%
- This hub holds employee KiwiSaver at 0% in both cash columns so tax + ACC take-home can tie
- Personalize enrolled employee rates in the New Zealand paycheck and sole trader calculators
GST registration
- Generally register when GST turnover is $60,000 or more
- Standard GST rate 15% (IRD) — for education only
- This hub flags registration likelihood; it does not model GST collected or remitted
Provisional tax
- May apply when residual income tax exceeds $5,000
- Hub instalment estimate = income tax ÷ 3 when provisional tax is likely — educational only
- Not IRD standard uplift, estimation, or AIM
PAYE withholding
- Employers usually withhold from each payday for employees
- Employee column on this hub shows NZ$0 provisional tax — withholding timing instead

Myths vs facts
“Sole traders always take home less cash than employees.”
On this NZ$50k vignette cash take-home ties at $41,987.00 — income tax and ACC earner levy match when employee KiwiSaver is held at 0% in both cash columns. The employee package adds employer KiwiSaver CEC for an eligible contributing member ($43,737.00 vs $41,987.00).
“Employer KiwiSaver comes out of my take-home pay.”
On this hub, employer KiwiSaver CEC is modelled on top of gross — it raises total package without reducing the cash take-home column. Employee KiwiSaver (when enrolled) does reduce cash take-home — personalize in the calculators.
“Opted-out employees still get employer KiwiSaver.”
No. IRD compulsory employer contributions apply when the employee is in KiwiSaver (or a complying fund) and KiwiSaver is deducted from salary or wages. This hub’s package column shows CEC for an eligible contributing member so you can see the employment retirement benefit separately from the cash tax comparison.
“Sole traders never deal with GST under NZ$100k.”
IRD GST registration generally applies from $60,000 GST turnover — not NZ$100k. This vignette flags likelihood when profit ≥ that threshold (expenses = 0).
“Provisional tax is the same as employee PAYE withholding.”
Employees usually have PAYE withholding each payday. Sole traders may pay provisional tax instalments toward an expected annual bill — different cash-flow timing even when the annual tax maths match.
“Company structures and expenses don’t matter.”
They can change the commercial result a lot. This hub excludes companies, trusts, deductible expenses, student loan, and ACC work levy so the equal-profit tax + employer KiwiSaver comparison stays readable.
Concepts
Same profit, same tax + ACC earner levy
With identical taxable income, employee KiwiSaver held at 0% in cash columns, and no student loan/expenses, income tax and ACC earner levy match — useful for isolating employer KiwiSaver package and timing.
Package vs cash
Cash take-home can tie while total package diverges because employer KiwiSaver CEC (eligible contributing member) sits outside the paycheck.
Cash-flow vs annual liability
PAYE withholding spreads collections; provisional tax can concentrate sole-trader cash outflows even when the annual bill matches employment.
GST flag, not GST maths
Registration likelihood from $60,000 turnover is flagged — collected/remitted GST dollars are not modelled.
Planning notes (education, not advice)
Budget for provisional tax
If provisional tax applies, plan instalment cash — not only an annual balancing payment after lodgement.
Self-fund KiwiSaver as a sole trader
Without employer KiwiSaver, consider how you will save for retirement; personal contributions have their own rules (not modelled here).
Watch the GST threshold
Track GST turnover toward $60,000 — registration changes invoicing and compliance even when this hub does not model GST amounts.
This is education, not advice
IRD pages and this hub do not replace a tax agent for contractor structuring.
Glossary
- PAYE withholding
- Pay As You Earn withholding — employers usually deduct income tax (and related amounts) from each payday and remit to Inland Revenue.
- Provisional tax
- May apply when residual income tax exceeds $5,000 (IRD). This hub’s instalment hint divides income tax by three for education only.
- Employer KiwiSaver
- Compulsory employer contribution (CEC) into an employee’s KiwiSaver at 3.5% from 1 Apr 2026 for eligible contributing members (IRD). Not deducted from the cash take-home on this hub. CEC does not apply when the employee has opted out and no KiwiSaver is deducted.
- Employee KiwiSaver
- Contribution rate chosen by the employee (or default when enrolled). This hub holds employee KiwiSaver at 0% in both cash columns so tax + ACC can tie — enrolled employees also pay employee KiwiSaver; personalize in the calculators.
- ACC earner levy
- 1.75% of liable earnings up to $156,641 for 2026/27 (IRD).
- ACC work levy
- Industry-based ACC levy for self-employed / employers. Not modelled on this hub (flag only) — no invented dollar amounts.
- GST registration threshold
- $60,000 GST turnover — IRD registration requirement. This hub flags likelihood only; it does not model GST collected or remitted.
- GST rate
- 15% standard rate (IRD) — shown for education; amounts not modelled here.
- Total package
- Cash take-home plus employer KiwiSaver CEC (eligible contributing member). Used for rankings on this hub because cash take-home ties when profit equals gross and employee KiwiSaver is held at 0% in cash columns.
- Same profit vignette
- Sole-trader trading profit set equal to employee gross so income tax and ACC earner levy match and only employer KiwiSaver package + timing/GST flags differ.
