Summary

The ad contrasts two claims: "BIGGEST TAX ON SMALL BUSINESSES IN NZ HISTORY" alongside one politician, and "TAX RELIEF FOR SMALL BUSINESSES" alongside another. The first is a specific historical superlative, while the second is a broader claim that current policy provides businesses with tax relief. National's Investment Boost does provide an additional tax deduction for qualifying business investment, but the claim that the alternative represents the biggest tax on small businesses in New Zealand history is not supported by the evidence.

Current policy does provide an additional tax deduction for qualifying business investment. However, there is no evidence in the ad or supporting material establishing that the alternative would constitute the biggest tax on small businesses in New Zealand history.

What the ad gets right

  • +Businesses can currently use Investment Boost to immediately deduct 20% of the cost of qualifying new assets, before depreciating the remaining 80%, so describing that policy as providing tax relief has a factual basis. ([Inland Revenue][1])
  • +Investment Boost is available to businesses of all sizes, including small businesses. ([National Party][2])

What the ad gets wrong or leaves out

  • −The ad provides no evidence establishing that the opposing policy would be the "biggest tax on small businesses in NZ history." A claim of this scale would require a historical comparison with previous taxes and tax increases.
  • −The apparent basis for the claim is that Labour proposes changing the existing Investment Boost scheme. National has described this as removing more than $5 billion of business support, but that is National's calculation of the difference between policy packages, not evidence of the biggest small-business tax in New Zealand history. ([National Party][3])
  • −Labour's published small-business policy also contains tax reductions or concessions: raising the GST registration threshold from $60,000 to $80,000 and increasing the immediate asset write-off threshold from $1,000 to $10,000 for businesses with turnover below $10 million. ([Labour Party][4])
  • −Removing or reducing an existing tax concession can increase tax liabilities relative to the status quo, but describing the entire policy change simply as a new "tax" obscures that distinction.
  • −The graphic presents a binary choice between a historic tax increase and tax relief without explaining that both approaches contain tax concessions for businesses, structured in different ways.

Detailed Verdict

The "tax relief" side is grounded in the existing Investment Boost deduction. However, the much stronger claim that the alternative is the "biggest tax on small businesses in NZ history" is not demonstrated and conflates reducing one tax concession with imposing a historically unprecedented small-business tax.
