1. The paradigm shift: taxing 'creation' vs. taxing 'velocity'
To understand the 20/7 model, we must first look at the philosophy of how a government funds a nation’s ambitions. For decades, New Zealand’s fiscal health has been tethered to a "Productivity Brake." This traditional model relies on vertical equity—the progressive idea that those who create more wealth should be taxed at a higher percentage. Under this system, the state taxes creation: it takes a slice of every dollar you earn (Income Tax) and every dollar a business makes in profit (Corporate Tax). Essentially, the harder you work and the more successful a firm becomes, the more the system "fines" that effort.
The 20/7 velocity engine completes a journey that began with the 1986 Douglas Reforms ("Rogernomics"). While those reforms shifted us toward a hybrid system, 20/7 finishes the transition by moving entirely from taxing production to taxing process—the flow of money through the economy. By "clipping the ticket" on transaction velocity rather than success, the system transforms from a barrier into a friction-less transaction fee.
| Feature | The productivity brake (current) | The velocity engine (20/7 model) |
| Primary target | Production: Fines what people earn and what businesses profit. | Process: Captures the flow of money through consumption and supply chains. |
| Psychological incentive | Discourages marginal effort (overtime) and expansion due to higher tax brackets. | Rewards effort; every extra dollar earned is kept entirely by the individual or firm. |
| Economic goal | Revenue through direct "fines" on labor and success. | Revenue through "velocity fees" on economic activity and spending. |
This administrative shift at the corporate level, however, is merely the foundation for the radical windfall awaiting the individual citizen.
2. The mechanics of the 20/7 model: tiered recovery with a 65% default
The technical core of this model is a tiered framework that replaces complex income taxes with a streamlined, unavoidable Goods and Services Tax (GST) system. The model utilizes a 20% universal GST on all invoices, with a 65% default recovery rule for most business purchases.
In our current system, businesses generally claim back 100% of the GST they pay on expenses. Under 20/7, most operational spend claims back 65% of the GST value. This is a deliberate administrative "hack" that turns the GST infrastructure into a proxy for a 7% turnover tax on business operations, ensuring every firm contributes based on its operational footprint rather than its accounting profit. Multi-stage price cascading (tax-on-tax through the chain) and targeted design responses (strict white list, tier-2 100% refund, and a narrow tier-1E 85% lane) are developed in that standalone note.
The math in practice (for a $100 business-to-business service):
- The invoice: A firm receives a bill for 100 + 20% GST (20), totaling $120.
- The refund: The business claims back only 65% of that GST value (65% of 20 = $13).
- The surcharge: The remaining $7 is "swallowed" by the business as a non-refundable operational cost.
Tiering note: where inputs are physically absorbed into a final sellable unit, statute can allow 100% recovery (tier 2). A narrow set of certified essential non-absorbed chain links may use 85% recovery (tier 1E). Both remain evidence-gated exceptions; the 65% default remains the core rule.
By replacing the 28% Corporate Income Tax (CIT) with this 7% operational surcharge, the state ensures a broad and resilient tax base. Even if a firm makes zero profit, it still contributes to the infrastructure it uses. This structural change at the business level creates the fiscal space for the most significant personal wealth-building event in modern history.
3. The household windfall: 100% take-home pay
For the average citizen, the 20/7 model represents a total liberation from Personal Income Tax (PIT). The "PAYE" deduction vanishes; you keep every cent you earn. While the model introduces a modeled 12–14% transition inflation range (using 14% as the central planning case) due to higher GST and business cost pass-throughs, the math for the individual reveals a massive net gain.
Financial position: standard Kiwi family ($140,000 gross income)
| Financial category | Current system | 20/7 model |
| Gross annual income | $140,000 | $140,000 |
| Tax paid at source (income tax) | ($31,000) | $0 |
| Take-home pay | $109,000 | $140,000 |
| Estimated cost of living | $85,000 | $96,900 (using 14% central planning case inflation) |
| Final discretionary savings | $24,000 | $43,100 |
The "Aha!" moment for the learner is the 2:1 ratio: while prices rise by 14%, the family’s cash-in-hand grows by 28%. By focusing on velocity, the system allows discretionary savings to nearly double. To ensure this acceleration doesn't leave the vulnerable behind, the blueprint includes robust, strategic safeguards.
Minimum wage earner, full-time (proof-of-fairness illustration)
The $140,000 household shows the mid-band windfall; the sharper test is someone on the statutory floor. At approximately $24.50 per hour in 2026 (40 hours), gross weekly pay is $980. Current PAYE (10.5% on the first $15,600 of annual income and 17.5% above that, expressed weekly) removes about $145, so take-home is roughly $835. Under 20/7, PAYE is $0 and the same gross yields $980 in hand—about a 17% lift in weekly cash before any wage increase.
Weekly cash versus the 14% central planning case spend shock (illustrative):
| Metric | Current system (weekly) | 20/7 model (weekly) |
| Gross pay (40 hrs) | $980.00 | $980.00 |
| Income tax (PAYE) | ($145.00) | $0.00 |
| Take-home pay | $835.00 | $980.00 |
| Same basket of goods after ~14% price lift | — | ~$951.90 (if prior spend equalled $835) |
| Residual after essentials (illustrative) | — | ~+$28.10 per week (~$1,460/year) |
Transfer gross-up: Working for Families, Accommodation Supplement, student allowances, and similar transfers are assumed to rise by about 15% so that a $200 weekly credit becomes roughly $230—explicit inflation protection on top of the PAYE gain. Overtime and abatements: extra hours are not clipped by PAYE brackets, and benefit taper rules bite less harshly on gross pay that is no longer pre-tax. Savings: interest is not taxed as personal income in this architecture, so frugal households can build balances without an annual income-tax return on small savers’ yields.
Rent caveat: residential rent is typically GST-exempt, but landlords still absorb the 7% operational wedge on rates, insurance, and maintenance. The framework assumes the Accommodation Supplement leg of the gross-up bears part of that pass-through risk; see the risk framework for the social-licence angle.
4. Social stability and strategic mitigations
To prevent a regressive impact and protect local industry from global loopholes, the 20/7 blueprint integrates four critical protections:
- The welfare gross-up: All benefits and Superannuation payments are increased by approximately 15%. This ensures that the most vulnerable citizens maintain their purchasing power in the face of higher shelf prices.
- The border equalization levy: To protect local brick-and-mortar stores from offshore giants (like Temu or Amazon) that lack NZ overheads, a 7% surcharge is applied to all consumer imports at the border.
- The reverse charge mechanism: To prevent firms from avoiding the tax net via "offshore invoicing," NZ companies buying foreign services (software, consulting) must self-assess the 20% GST and are subject to the same 65% recovery limit.
- Targeted anti-cascade relief: Strict absorption-based tier 2 classification and a narrow, evidence-gated tier 1E lane reduce long-chain snowballing while preserving one 20% invoice rate.
- Anti-monopoly oversight: The Commerce Commission is given a specific mandate to prevent tax-motivated vertical integration. This prevents large firms from firing external small-business contractors to hire in-house staff solely to dodge the 7% operational tax.
These protections ensure that the structural efficiency of the state remains intact while the economy accelerates.
5. The death of bureaucracy: halving the IRD
The 20/7 model shifts the Inland Revenue Department (IRD) from a "forensic" system—investigating lives and profits—to a "transactional" system, where tax is captured as money moves.
| Task | Current bureaucratic headaches | 20/7 streamlining |
| Individual filings | Millions of returns, PAYE codes, and audits. | Zero. Returns are abolished. |
| Business reporting | Complex profit, FBT, and depreciation math. | Zero. Tax is "clipped" off invoices. |
| Government focus | Tracking "profit" (easily hidden/gamed). | Tracking "spending" (hard to hide). |
The economy becomes effectively self-policing. Because spending is far more difficult to hide than income or profit, the need for a massive, investigative bureaucracy is halved, allowing the state to pivot from auditing its citizens to simply monitoring the flow of the engine—within the limits of cash consumption and refund integrity spelled out in the risk framework.
6. Synthesis: the $3.1 billion result
The 20/7 transformation functions as a powerful supply-side catalyst. By removing the "handbrakes" on individual effort and business success, it creates an environment where wealth is created and reinvested without penalty.
The fiscal reality of this shift is grounded in precise 2026/27 projections:
- The replacement cost: Abolishing Income Tax, Corporate Tax, and funding the welfare gross-up costs $86 billion.
- The projected yield: The new 20% retail GST and 7% operational surcharge generate $89 billion.
This results in a projected $3.1 billion annual surplus. By trading a high-friction, punitive tax system for a low-friction, high-velocity model, New Zealand positions itself as a global outlier. It is a system built for a nation that no longer wants to fine success, but instead wants to power it.
