Small Business Tax Planning: Knowing When You Need an Expert

- You have started paying provisional tax
- You are registered for GST and filing returns
- You own rental property or several business structures
- You are unsure which expenses you can claim
A good adviser explains your options in plain terms, and expert tax advice should also cover the rules that apply to your business type. If you have decided to get help, see how to engage a chartered accountant for your tax return. Tax rules can change, so check the Inland Revenue business tax guidance for current requirements.

| Unsure which expenses you can claim | Wrong claims create risk | Check with an expert |
Business Tax Deductions and the Records That Support Them

Frequently Asked Questions
How do I find a tax adviser for my small business?
Look for a chartered accountant or a registered tax agent who works with businesses of your size and type. Ask whether they have experience with your industry, such as trades, hospitality or retail, and whether they will handle GST, provisional tax and payroll as well as your annual return. Check how they communicate and who you will deal with day to day. Pricing depends on the work involved, so ask for a written quote and a clear scope before you commit. Macro Accounting can provide current pricing and a quote on request through its website.
What tax records should a small business keep?
Keep sales invoices, purchase receipts, bank statements, payroll records, GST returns and any contracts or agreements that affect income or expenses. For deductions, the record should show the date, the amount, the supplier and the business purpose of each cost. Store records digitally in a way you can search and back up, and keep them for the period required under New Zealand tax law. A tidy system makes preparing your return faster and makes any later query from Inland Revenue easier to answer.
Can an accountant help with GST and payroll?
Yes. A tax adviser can prepare your GST returns, check which expenses can be claimed, and plan for the cash needed to pay GST on time. Many also process payroll, calculate PAYE and file the required employer returns with Inland Revenue. Combining GST, payroll and annual tax under one adviser means fewer gaps between your records and your filings, and one person who understands your full financial picture.
