There is a moment most experienced Bookkeepers will recognise.
You’re working through a client’s accounts and something catches your eye.
Maybe there’s a payment that doesn’t quite match the usual pattern. A contractor arrangement has changed. There are suddenly more cash transactions than normal. Some documentation is missing. Or the numbers technically reconcile, but something about them just doesn’t make sense.
Would you spot the red flag?
More importantly, would you know what to do next?
Sometimes, asking that question is where the real value of a Bookkeeper begins.
Inland Revenue is increasing its focus on horticulture
In August 2026, Inland Revenue issued Revenue Alert RA 26/02 outlining concerns about non-compliance in New Zealand’s horticultural sector.
In particular, Inland Revenue identified concerns around:
- withholding tax not being correctly deducted from schedular payments
- contracting arrangements being used to obscure the true nature of transactions
- false invoices
- workers being paid in cash
- broader non-compliance with GST, PAYE and income tax obligations.
Inland Revenue says it is increasing its focus on growers, contractors and subcontractors and, where concerning behaviour is identified, taxpayers may be investigated further.
That makes this an important alert for any Bookkeeper working with clients in horticulture.
But there’s also a useful lesson here for Bookkeepers working across other industries.
Compliance often starts with the records
One of the interesting things about the Revenue Alert is how many of the issues Inland Revenue identifies would eventually show themselves in the financial records of a business.
Invoices. Contractor payments. Payroll. GST. Cash transactions. Tax deductions. Supporting documentation.
In other words, the exact information Bookkeepers work with every day.
That doesn’t mean it’s the Bookkeeper’s job to investigate their clients or determine whether an arrangement is legally compliant.
It does mean Bookkeepers are often in a very good position to notice when something has changed, doesn’t add up or needs to be checked.
Good bookkeeping compliance isn’t simply about getting every transaction into the right account.
It’s also about helping clients maintain the systems, records and processes that support their wider tax obligations.
What should Bookkeepers be looking out for?
For Bookkeepers with horticultural clients, the Revenue Alert provides some particularly practical areas to review.
For example, payments for cultivation contract work can be subject to the schedular payment rules, including payments made to companies. Inland Revenue states that the payer is responsible for withholding tax unless the contractor has provided appropriate evidence of a valid exemption or a tailored tax rate certificate with a 0% deduction rate.
Inland Revenue also reminds payers that relevant records need to be retained for at least seven years. These can include IR330C tax rate notification forms, certificates of exemption, tailored tax rate certificates and other evidence relied upon when determining the tax treatment of payments.
Importantly, certificates of exemption and tailored tax rates are issued for a year ending 31 March. Contractors need to renew them each year and payers need to ensure the certificate they hold is current.
Those are practical checks a Bookkeeper can help a client build into their processes.
Are we treating contractor payments correctly?
Don’t assume that because someone invoices through a company, withholding obligations automatically disappear. If you’re unsure how a payment should be treated, flag it with the client’s accountant or tax advisor.
Do we have the documentation to support the treatment?
A process is much easier to support when the records behind it are sitting exactly where they should be.
Are certificates still current?
Something that was correct last year may not be correct this year. Annual checks can prevent an expired certificate from quietly becoming a compliance problem.
Do the invoices make commercial sense?
Inland Revenue specifically raises concerns about invoices issued by entities that did not actually perform the work. Bookkeepers aren’t investigators, but an unusual supplier, unexpected change in invoicing or transaction that doesn’t fit the client’s normal operations can be worth querying.
Are cash payments being properly recorded and accounted for?
Cash isn’t automatically a problem. Undocumented or incorrectly treated cash transactions can be.
And this isn’t only a horticulture lesson
The specific tax rules discussed in the Revenue Alert relate to the horticultural sector and should not simply be applied to clients in other industries.
But the broader bookkeeping compliance lesson travels very well.
Think about a tradie who suddenly starts using a new subcontractor.
A hospitality business with increasing cash payments.
A professional services client paying someone as a contractor when the arrangement looks different from their other contractors.
A client who says, “That’s how we’ve always done it”, but nobody can find the paperwork supporting why it’s being done that way.
Different industries have different rules and risks.
The Bookkeeper’s role remains remarkably similar: keep accurate records, understand the client’s usual processes, notice when something changes and ask questions when something doesn’t look right.
You don’t have to have all the answers
This is perhaps the most important part.
Being a great Bookkeeper doesn’t mean being expected to know every section of the Income Tax Act or determine whether a complicated contracting arrangement is lawful.
There is a big difference between identifying a potential issue and advising a client on how the law applies to their specific circumstances.
Your value can be as simple as saying:
“This doesn’t look like the way we’ve normally treated these payments. I think we should check it with your accountant or tax advisor before we continue.”
That’s not stepping outside your lane.
That’s recognising where your lane ends.
The best compliance problem is the one caught early
Inland Revenue’s Revenue Alert makes it clear that it considers non-compliance in the horticultural sector a significant risk and is increasing its scrutiny, including around withholding obligations, certificates of exemption, tailored tax rates, GST registrations and outstanding debt.
Where the concerns outlined in the alert may apply, Inland Revenue recommends discussing the situation with a tax advisor or Inland Revenue and considering whether a voluntary disclosure is appropriate.
For clients who are doing everything correctly, good systems and records help demonstrate that.
For clients who have made an honest mistake, identifying it early gives them the opportunity to get appropriate advice and address it.
And for Bookkeepers?
It is another reminder that the value you bring isn’t just in what you enter into the accounting software.
It’s in what you notice along the way.
Know when to ask the next question
Good bookkeeping compliance is a team effort. Bookkeepers, accountants, tax advisors and clients all have different roles to play.
You don’t need to become the tax expert in the room.
But you can be the person who notices that something doesn’t look right and asks the question before a small issue becomes a much bigger one.
And that is a pretty valuable place to be.
