Labour has confirmed it would, if elected, scrap the coalition government's Investment Boost policy and replace it with a small business-focused tax and compliance package, including a higher instant asset write-off threshold, a lifted GST registration threshold, and mandatory payment-time rules for large firms.

The party's small business spokesperson, Dan Rosewarne, framed the package around reducing administrative burden. "Running a small business should mean building something of your own, not spending evenings chasing overdue invoices and filling in forms," he said. Labour leader Chris Hipkins said under a Labour government small business owners would "get paid sooner, get more support to invest in the equipment they need, and keep more of what they earn."

The centrepiece tax change would lift the instant deduction threshold for small businesses buying equipment or tools from $1,000 to $10,000. Under Labour's plan, small businesses would be able to immediately deduct the cost of new equipment from their tax bill, rather than depreciating it over time. The existing Investment Boost — the coalition's broader accelerated depreciation mechanism — would be replaced entirely (RNZ).

On the GST side, Labour would raise the registration threshold from $60,000 to $80,000. The party estimates about 35,000 businesses would no longer need to register for GST as a result, pulling them out of the filing and return cycle altogether.

On late payments — a long-standing grievance for small suppliers — Labour would require large businesses to pay small suppliers within 15 days for invoices worth up to $25,000. Big businesses would also be required to publish how quickly they pay their suppliers, a transparency measure Labour says would create competitive pressure on payment times.

The broader fiscal architecture behind Labour's spending commitments remains its proposed capital gains tax. Labour has said the tax would apply a targeted 28 percent rate on profit from the sale of commercial or residential investment property, excluding the family home, farms, KiwiSaver, shares, businesses and inheritances (Labour Party policy page). The party says every dollar raised would be ring-fenced for health, and that nine out of 10 New Zealanders would not pay it. The CGT policy is undated on Labour's website and predates today's small business announcement.

The political calculation is straightforward enough. Investment Boost, as designed by the coalition, applies across the full spectrum of business asset purchases regardless of firm size. Labour's replacement narrows that benefit to small businesses, redirecting the fiscal headroom toward the GST threshold shift and the payment-time mandates. That positions the policy as a direct appeal to the small business constituency the party has historically struggled with, while drawing a clear line between itself and the coalition on the question of who tax policy should favour.

For those working in and around the Beehive, the packaging is familiar territory. Labour is combining a tax cut (the write-off lift), a tax exemption (the GST threshold), and a regulatory mandate (the 15-day payment rule and transparency requirement) into a single small business narrative. The CGT funds the health side of the ledger; the small business package stands on its own as a targeted reweighting of existing coalition policy rather than new net spending in the conventional sense.

The 15-day payment mandate will draw the most pushback from the business lobby. Large firms routinely operate on 30-to-60-day payment cycles to manage cash flow, and mandatory disclosure of payment times would expose variation that many would prefer kept internal. Whether a Labour government could legislate this cleanly without unintended consequences for supply chain dynamics is a question select committee scrutiny would probe.

The GST threshold lift carries its own trade-off. Pulling 35,000 businesses out of the GST net simplifies their compliance burden, but it also means those businesses cannot claim back GST on their own inputs — a cost that eats into margins for firms with significant purchasing requirements. The $20,000 threshold increase is modest in nominal terms, and whether it meaningfully changes behaviour at the margin depends on the profile of the businesses captured in that band.

Labour has not released costings for the small business package separately from its broader fiscal plan. The CGT revenue is earmarked for health, which means the write-off lift, the GST threshold change, and the payment mandate would need to be funded from elsewhere in Labour's fiscal programme, or offset against the revenue forgone from replacing Investment Boost. How that arithmetic stacks up against Treasury's baseline will be a point of scrutiny when the full fiscal plan is released.
