Welcome to TaxTrack by Prosper Business.

Know where you stand with tax.

Take the guesswork out of saving for tax.

TaxTrack is an online tax planning calculator designed to help New Zealand business owners estimate their income tax and GST position, understand how their tax savings are tracking, and plan ahead with a little more confidence.

Because knowing you're making a profit is one thing. Knowing whether you've put enough aside for tax is another!

How TaxTrack can help

1

Estimate your tax position

Use your business figures to estimate your income tax and GST position throughout the financial year, rather than waiting until your annual accounts are prepared.

2

See how your savings are tracking

Compare your estimated tax owing with the money you've already saved. See whether you're ahead, on track, or have a savings gap to plan for.

3

Plan for outstanding invoices

See how transferring some of the money from unpaid customer invoices into your tax savings could improve your position once those invoices are collected.

4

Check in whenever you like

As your business changes, so can your tax position. Update your figures and run a fresh estimate whenever you need to.

Who is TaxTrack for?

TaxTrack is designed for NZ business owners who want a better understanding of their tax position throughout the year.

It could be a good fit if you:

  • Run a sole trader business or a company with up to two shareholders.

  • Use accounting software and can access your financial figures.

  • Want to understand how much tax you might need to save.

  • Prefer a practical, self-service tool rather than ongoing management reporting.

  • Want to be more proactive about managing your business cashflow.

TaxTrack is best suited to businesses with relatively straightforward tax affairs. More complex situations may require personalised advice from your accountant.

How it works

1. Gather your figures

Use your accounting software and myIR to find your profit, GST, tax payments and savings balances. Our step-by-step guide will show you where to look.

2. Enter your information

Add your figures into TaxTrack, including shareholder information and other taxable income where relevant.

3. Review your results

See your estimated income tax, GST and savings position, including any gap between what you may owe and what you've already saved.

4. Make a plan

Use your results to consider whether you need to adjust how much you're regularly putting aside for tax.

You can return and run updated estimates throughout your membership.
