New Zealand's core Crown tax revenue reached $31.5 billion in the three months to 30 September 2026, $420 million or 1.2 percent above the Pre-election Economic and Fiscal Update forecast.
Tax Revenue Outperforms Forecast
Treasury released its Tax Outturn Data for September 2026 on 5 November 2026. The figures cover the first quarter of the 2026/27 fiscal year.
Unconsolidated tax revenue totalled $420 million more than the PREFU projection. This represents an 8.7 percent increase on the same period last year.
Corporate tax and net other individuals' tax drove the outperformance. These categories benefited from stronger terminal tax collections.
Receipts and Broader Fiscal Position
Tax receipts came in $58 million or 0.2 percent below the PREFU forecast. They were still $395 million or 1.2 percent higher than the prior year.
Core Crown expenses for the quarter reached $37.4 billion. This was $0.5 billion below the PREFU expectation.
The OBEGALx deficit stood at $2.8 billion. The result was $1.3 billion smaller than forecast in PREFU.
The operating balance recorded a $0.9 billion surplus. PREFU had projected a $2.9 billion deficit.
Comparison to Recent Outturns
The September result continues a pattern of positive surprises. Full-year FY2025/26 delivered an OBEGALx deficit of $8.7 billion. This came in $3.3 billion better than the Budget 2026 forecast.
PREFU itself revised core Crown tax revenue upward by $11.4 billion over the four-year forecast horizon compared with Budget 2026.
Implications for Incoming Government
The stronger starting position provides additional fiscal headroom. Net core Crown debt already sits lower than expected after the prior year's outperformance.
Core Crown tax revenue for three months ended 30 September 2026 was $31.5 billion, $0.3 billion higher than PREFU forecast, driven by stronger corporate and net other individuals' tax from terminal tax.
Markets and analysts incorporated the PREFU upgrades into forecasts. Banks including ASB and BNZ highlighted narrower deficits and a reduced borrowing programme.
Subsequent monthly outturns will confirm whether the momentum continues through the rest of the year.
