Tax bill simplifies FBT vehicle rules, lifts FIF threshold to $100k

A substantial tax bill introduced to the House would replace motor-vehicle fringe benefit tax day-counting with six private-use categories from 1 April 2027 and lift the Foreign Investment Fund de minimis to $100,000.

Revenue Minister Simon Watts has introduced an omnibus tax bill that would scrap detailed motor-vehicle fringe benefit tax (FBT) logbooks in favour of a six-category private-use system from 1 April 2027.

The changes track Budget 2026 announcements of 28 May 2026. They sit inside a consolidation Budget still forecasting OBEGALx deficits of $11.9 billion (2.6% of GDP) in 2025/26 and $11.4 billion (2.4% of GDP) in 2026/27.

Watts said the Bill would reduce compliance costs, simplify rules and remove unnecessary obligations. On vehicles he proposed a simpler "close enough is good enough" approach.

For fringe benefit tax, we're proposing a much simpler 'close enough is good enough' approach to employer-provided vehicles.

Six categories replace the logbook

Employers would classify each vehicle when allocated and revisit only if expected private use changes materially. Incidental private use would be ignored. The long-standing work-related vehicle exemption would be abolished and folded into the categories. A clean exemption is proposed for certain emergency vehicles.

Proposed inclusion rates are:

• Full private or perk use: 100%
• Partial private use: 35%
• Farm shareholder-employee vehicles: 35%
• Single-worksite commute-only: 20%
• Multi-worksite branded commute: 0%
• Pool or no private use: 0%

Cost-base valuation rates would also reset. The standard annual rate would rise from 20% to 22.8%. Hybrids would be 19.6% and electric vehicles 17.0%, with parallel tax-book-value rates. Inland Revenue's May 2026 information sheet sets application for benefits provided after 1 April 2027.

Treasury scores the FBT redesign at about $0.6 million over the forecast period—broadly revenue-neutral by design. Advisers say outcomes will not be firm-by-firm neutral.

BDO Associate Director Sandita Singh said the reforms are the most practical simplification of motor vehicle FBT rules in many years and should significantly reduce compliance costs for most businesses. BDO and Deloitte note perk and remuneration-package cars may face higher FBT, while branded tool-of-trade fleets with tight private-use policies should see lower effective inclusion.

The proposed reforms represent the most practical simplification of motor vehicle FBT rules in many years. The shift from day-counting and technical exemptions towards a category-based system should significantly reduce compliance costs for most businesses.

Deloitte also said existing rules discouraged electric vehicles. Lower EV and hybrid valuation rates could ease corporate uptake and, over time, second-hand supply.

FIF de minimis doubles to $100,000

The same Bill advances Foreign Investment Fund (FIF) reforms Budget 2026 scored at a $72.5 million revenue cost over five years (2025/26–2029/30).

The de minimis cost threshold—unchanged since 2000 at $50,000—would rise to $100,000. Inland Revenue says the lift fully accounts for CPI inflation since 2000 and restores real value. Smaller direct offshore investors would drop out of annual Fair Dividend Rate (FDR) or Comparative Value calculations.

The Revenue Account Method (RAM), enacted in March 2026 for recent migrants only, would open to all New Zealand residents for unlisted foreign shares. RAM taxes actual dividends plus 70% of realised gains. Extended RAM would also cover listed shares for residents facing concurrent foreign tax, chiefly US persons.

Further FIF proposals would let founders who dilute below 10% keep the attributable FIF income method if still active, and preserve the 10-year corporate-migration exemption through SPAC-style listings. Inland Revenue targets application from 1 April 2026 for the 2026–27 year once enacted.

Integrity measures fund the simplification

Budget 2026 integrity measures are intended to offset the simplification costs. Taxing outstanding loans to shareholders after company removal from the register is scored at roughly $146–152 million. Aligning thin capitalisation for foreign-owned banks to Reserve Bank prudential settings is scored at $45.2 million. Extra Inland Revenue compliance funding is scored at about $120 million net. An RDTI redesign, including a cut in the internal software cap from $25 million to $3 million, is scored as an $84.6 million net save.

Election-year timing risk

Process risk is material in an election year. Deloitte noted the May/June Budget Measures bill enacted only a subset of tax items. FBT categories and the main FIF package were always slated for a later annual-rates omnibus. Incomplete bills lapse on dissolution and must be reinstated. Select-committee timing will decide whether the 1 April 2026 and 1 April 2027 start dates hold.

Until Royal assent the live FIF de minimis remains $50,000. Employers should map fleets to the six categories, update private-use policies and branding, and retain evidence even without daily logbooks. Investors should treat de minimis and RAM expansion as proposed law only.

For New Zealand trades, agriculture, sales fleets and emergency services, the FBT shift is the highest-frequency operational change. For households with $50,000–$100,000 cost-basis offshore portfolios, and for unlisted startup and dual-taxed residents, the FIF package is the main relief. Delivery still depends on Parliament completing the omnibus before the election clock runs out.
