Queenstown Lakes runs one of the most concentrated seasonal economies in New Zealand. A significant share of local businesses earn the bulk of their annual revenue across a handful of peak months and spend the rest of the year covering fixed costs from reserves. The tax system, by contrast, is largely built around businesses that earn steadily.
That mismatch is manageable, but only if the structural choices are made deliberately.
The core problem
Provisional tax instalments fall on fixed dates through the year regardless of when income arrives. A business earning most of its profit between December and March pays instalments in months when it has no revenue, funded from cash it needs for wages and rent.
The same applies to GST. On the invoice basis, GST on a busy month is payable whether or not the money has arrived, and for operators with corporate or wholesale customers on long terms, it frequently has not.
The three levers worth pulling
The accounting basis for GST. The payments basis, available below a turnover threshold, means GST is accounted for when money actually moves. For a seasonal business with any credit exposure, this materially smooths the position. Businesses that have grown past the threshold lose the option, which is one of the less obvious costs of growth.
The provisional tax method. The Accounting Income Method calculates provisional tax from actual year-to-date results at each instalment, so a quiet winter period generates a small payment rather than a payment based on last summer. For genuinely seasonal businesses this is the single most useful option available, and it is under-used.
The condition is real bookkeeping discipline. AIM requires accounts to be current, coded and reconciled at every instalment date. Operators who catch up quarterly should not use it.
Filing frequency. Two-monthly GST spreads the administration but produces payments in low-revenue months. Six-monthly reduces the paperwork and concentrates the cash impact. Neither is obviously right; the choice should follow the shape of your year rather than convenience.
The reserve discipline
Every seasonal operator who avoids trouble does the same thing: taxes are moved out of the operating account as revenue arrives, not budgeted for later. A fixed percentage of every takings deposit into a separate account, untouched, removes the decision at the point where the temptation is strongest.
The temptation is real in a tourism economy, because the peak generates cash that feels like profit. It is not. It is a year’s trading arriving in four months, and a substantial share belongs to Inland Revenue, to staff in the off-season, and to fixed costs that continue when the visitors do not.
Staffing costs that persist past the season
Holiday pay accrues on the earnings that generated it, which means peak-season wages generate a leave liability that crystallises later. Businesses that treat holiday pay as an operating cost of the month it is taken, rather than a liability accruing through the peak, find the off-season considerably harder than it needed to be.
The same applies to KiwiSaver employer contributions, which rose to 3.5 percent from 1 April 2026 and rise again in 2028. On a large seasonal payroll that is a real number.
Talking to the bank before you need to
Lenders understand seasonality, and a business that presents a monthly cashflow forecast showing the trough and how it will be funded gets a far better response than one that arrives in the trough asking for help.
An overdraft sized to the seasonal swing, arranged in the peak when the numbers look strong, is easier to obtain and cheaper than emergency funding arranged in August.
What applies beyond Queenstown
The same structural issues apply to any seasonal New Zealand business — ski operators across Otago and Canterbury, coastal accommodation in the Bay of Plenty and Northland, horticulture in Hawke’s Bay, and West Coast tourism. The concentration differs; the mechanics do not.
Inland Revenue publishes guidance on AIM, GST accounting bases and provisional tax options free at ird.govt.nz. The choice between methods is one of the genuinely high-value conversations to have with an accountant, and it is best had before a year starts rather than during it.
