Tax-to-commons pathways are the fiscal mechanisms through which a jurisdiction redirects a portion of its tax flows into a state-recognized Bioregional Financing Facility (BFF). A sound understanding of Modern Money Theory (MMT) is important to adopt or propose one of these pathways. They are a specific application of transvestment, the directional crossing of capital between value regimes, to the domain of public revenue. Where the Five Transvestment Pathways describe what a private wealth holder does with personal capital, tax-to-commons pathways describe what a polity does with its collective revenue obligation.
The distinction is important because private transvestment depends on the decision of an individual patron. Fiscal transvestment depends on a policy decision, which means it requires a proposal, a legal basis, an institutional recipient, and a governance structure the state can recognize. A BioHub that wants to activate this pathway must assemble all four. This concept note provides sufficient detail for any BioHub to prepare a tax-to-commons pathway that works for their jurisdiction.
The fiscal premise
The Sound Finance entry documents the operational reality underneath the popular claim that “taxes fund government spending.” For a currency-issuing sovereign, tax payments drain reserves from the banking system; they do not accumulate in a government savings account that then pays for services. Taxes are merely what keeps the currency circulating in a developed society; taxes do not fund government services. The Federal Reserve, the Bank of England, and the mechanics of South Africa’s National Revenue Fund all confirm the reserve-drain finding. However, the strong MMT claim that tax receipts are “destroyed” is a theory-laden interpretation of that finding, contested by mainstream economists. That said, the underlying accounting mechanic is primary-source confirmed as follows: Rather than funding government expenditures, taxes serve to drive demand for the currency.
What the reserve-drain finding means for transvestment policy is this: the fiscal constraint on redirecting tax flows is political and legal, not operational. A currency-issuing government does not run out of its own currency. The binding constraints are the constitutional and statutory rules governing how revenue may be allocated (South Africa’s National Revenue Fund provisions at ss.213-215 of the Constitution; the UK Consolidated Fund; the US appropriations process) and the political economy of proposing that any portion of tax flow leave the conventional spending circuit. Both constraints are real. Neither is the constraint the popular story describes.
A BioHub proposing a tax-to-commons pathway does not need its municipal council to accept MMT. It needs the council to recognize that existing legal mechanisms already permit the redirection the BioHub is proposing, and that the institutional recipient, the BFF, is a structure the law can recognize.
What a transvestment policy proposal requires
A BioHub preparing a tax-to-commons proposal for its jurisdiction needs four components. The components are jurisdiction-dependent in their specific legal form but structurally consistent across all documented cases.
1. A legal hook
The proposal must attach to an existing statutory mechanism that permits or mandates the redirection of tax revenue toward environmental, developmental, or community purposes. Creating new legislation is possible but slow, expensive, and politically exposed. The faster path is to identify a mechanism already in the jurisdiction’s law and propose its activation or extension. Four classes of legal hook have been documented across multiple jurisdictions.
Percentage designation laws. Hungary’s Act CXXVI of 1996 (the “1% Law,” operative from 1997) allows taxpayers to designate 1% of personal income tax to a qualifying NGO and a further 1% to a church or state fund. The model spread to Slovakia, Lithuania (2002/2004), Poland, Romania, Portugal, and Spain. It was itself modeled on Italy’s otto per mille (1990). The International Center for Not-for-Profit Law (ICNL) reports that approximately $15.76 million was designated to Hungarian NGOs in 2001. The mechanism gives individual taxpayers agency over a defined fraction of their obligation. A BFF incorporated as a qualifying entity under such a law becomes a designated recipient.
Ecological fiscal transfers. Brazil’s ICMS-E (“Ecological ICMS”), pioneered in Paraná state in 1991, redistributes a fraction of state value-added tax (ICMS) to municipalities based on protected-area coverage. Sixteen of twenty-six Brazilian states have adopted it. Portugal embedded ecological fiscal transfers in its Local Finances Law (2007). France adopted a variant. The mechanism redirects intergovernmental transfers on ecological performance criteria. A BioHub whose coordination work produces measurable ecological outcomes (restored water yield, expanded biodiversity corridor coverage, reduced invasive-species density) can propose that its municipality’s transfer allocation be weighted by those outcomes.
Property rates differentiation. South Africa’s Municipal Property Rates Act of 2004 requires rates policies to promote “local, social and economic development” and allows differential or exempt rating of conservation land, including land under the Protected Areas Act or the National Environmental Management: Biodiversity Act. The Municipal Fiscal Powers and Functions Amendment Bill (published for comment January 2020) would give municipalities express power to levy development charges. No South African municipality has yet ring-fenced rates revenue for ecological restoration or commons economic development, but the statutory hooks exist.
Municipal currency acceptance. Legal scholar Rohan Grey (“Monetary Resilience”) and Steve Randy Waldman (Interfluidity) propose municipalities issuing complementary currencies anchored in their acceptability for local taxes, fees, or fines. The Wörgl stamp scrip of 1932 is the operational precedent: the Austrian municipality accepted the scrip for local tax payments, which drove primary demand for the unit. The Money on the Left Collective (2025) sketches a movement-based version accepted for partial tax payments. The mechanism converts the municipal tax obligation itself into the demand driver for a bioregional currency, closing the loop between fiscal transvestment and the demurrage-based currency the BFF would eventually issue.
2. An institutional recipient the state can recognize
The legal hook directs revenue toward a destination. That destination must have a legal form the jurisdiction recognizes as competent to receive and administer public funds. A BFF, as specified by Power and Seefeld (2024), is a phased institutional architecture: bioregional trust, venture studio, investment company, bioregional bank. At early stages, a BFF will not have all four entities in operation. The minimum viable institutional recipient is a trust or cooperative with the governance characteristics the jurisdiction’s public-finance law requires: audited accounts, a board with fiduciary duty, reporting obligations, and (in South Africa’s case) compliance with the Municipal Finance Management Act.
The institutional form determines what classes of public revenue the recipient can absorb. A Section 21 company (South Africa) or a 501(c)(3) (United States) can receive designated tax revenue under percentage-philanthropy laws but cannot issue currency. A cooperative bank licensed under the Cooperative Banks Act (South Africa, Act 40 of 2007) or its jurisdictional equivalent can accept deposits and, potentially, issue complementary currency, but is subject to prudential regulation. The BFF’s phased architecture is designed for this: each institutional phase unlocks a new class of fiscal pathway.
3. A measurable deliverable
No tax-to-commons pathway survives political scrutiny without a deliverable the polity can evaluate. The BioConomy’s approach here diverges from the carbon-market approach that dominates climate fiscal policy. Carbon markets and green quantitative easing (the subject of proposals like the 2026 npj Climate Action paper on green monetary policy) operate through financial abstraction: emissions permits are traded on secondary markets, green bonds fund portfolios of projects selected by financial intermediaries, and the connection between the fiscal mechanism and the physical landscape is mediated by layers of financial engineering. The measured climate impact is correspondingly diffuse. The ECB’s own Working Paper No. 2701 (Abiry et al., 2022) found that green QE reduces global temperature by 0.04 degrees Celsius by 2100, roughly one-quarter the effect of a moderate carbon tax.
The BioConomy’s fiscal pathway produces a different kind of deliverable because the BFF funds physical work done in place by people who live in the bioregion. Restored hectares of water-retention landscape. Kilometers of biodiversity corridor cleared of invasive species. Cubic meters of additional water yield measured at the catchment level. Households participating in the bioregional coordination surface. These are outputs a municipal council can see, walk to, and measure with instruments already in the jurisdiction’s monitoring infrastructure. The deliverable is not a financial return. It is an ecological and coordination return denominated in physical units the polity already tracks.
The Three-Feature Test applies here: a tax-to-commons pathway that produces measurable ecological outcomes, operates through a governance structure the community controls, and creates standing for participants who would otherwise be excluded from the coordination economy passes the test. A pathway that produces financial returns to distant investors, operates through intermediaries the community cannot govern, or creates no new standing for local participants fails it, regardless of its ecological claims.
4. A governance structure the community controls
The governance question is where fiscal transvestment parts company with conventional environmental earmarking. Most ecological fiscal transfers (Brazil’s ICMS-E included) redirect revenue through existing municipal governance structures. The municipality receives the transfer; the municipality decides how to spend it. The ecological criterion determines the size of the transfer, not its governance.
A BFF is governed by its founding compact, not by the municipal administration alone. The Founding Compact is a governance document negotiated among the BioHub’s constituent entities: the community organizations, the traditional authority structures, the landholders, the ecological practitioners, and the municipal government as one participant among several. The compact specifies decision rights, accountability mechanisms, and the conditions under which the BFF can receive, hold, and deploy public funds.
This governance structure is the element most likely to meet resistance from municipal authorities accustomed to discretionary control over fiscal resources. The BioHub’s proposal must make the case that shared governance produces better ecological outcomes than discretionary municipal spending, and that the accountability mechanisms in the founding compact are at least as rigorous as those in the Municipal Finance Management Act or its jurisdictional equivalent.
Staging
A BioHub does not propose all four legal hooks simultaneously. The staging follows the BFF’s own phased development.
Stage 1: Property rates differentiation (immediate). Where the jurisdiction permits differential rating of conservation land, the BioHub seeks designation of commons-trust land under the applicable statute. This is a defensive move: it reduces the fiscal burden on land the BFF holds, freeing operating resources. It requires no new legislation, only a rates-policy amendment by the municipal council.
Stage 2: Ecological fiscal transfer or percentage designation (year 1-3). Once the BioHub can demonstrate measurable ecological deliverables, it proposes that a fraction of the jurisdiction’s intergovernmental transfer be allocated on ecological performance criteria, or that the BFF be listed as a qualifying recipient under a percentage-designation law. This is the first active revenue channel. It requires either a national/provincial policy change (ecological fiscal transfer) or the BFF’s registration as a qualifying entity under existing law (percentage designation). The Brazilian ICMS-E and Hungarian 1% Law are the documented precedents.
Stage 3: Municipal complementary currency (year 3-5). Once the BFF has an operational trust and a track record of ecological and coordination deliverables, it proposes that the municipality accept a bioregional currency unit for a defined fraction of local rates, fees, or fines. This converts the municipal tax obligation into a demand driver for the bioregional currency, closing the loop between the fiscal pathway and Pathway B of the private transvestment framework. The legal requirements are jurisdiction-dependent and, in most cases, untested. The Wörgl precedent operated under Austrian municipal law in 1932 and was shut down by the Austrian National Bank in 1933. A contemporary proposal would need to navigate central-bank regulatory authority, legal-tender statutes, and (in South Africa) the South African Reserve Bank Act.
The staging is designed so that each stage produces evidence that de-risks the next. Rates differentiation demonstrates the municipality’s willingness to use fiscal instruments for ecological purposes. Ecological fiscal transfers demonstrate measurable outcomes. Municipal currency acceptance demonstrates that the bioregional economy has matured enough to sustain a unit of account the polity trusts.
Constraints
Constitutional and statutory constraints are real. South Africa’s Constitution (ss.213-215) mandates that all national revenue be paid into the National Revenue Fund and withdrawn only by appropriation. The Public Finance Management Act operationalizes this. Municipal revenue is separately governed under the Municipal Finance Management Act. A tax-to-commons proposal must work within these frameworks, not around them. The relevant openings are in the rates-policy discretion the Municipal Property Rates Act grants to councils, and in the intergovernmental fiscal transfer formula that provincial and national government control.
Ecological fiscal transfer effectiveness is mixed. Brazil’s ICMS-E is real, widely copied, and the most successful documented case. It is also “self-limiting” (Ruggiero et al., 2022): the incentive to expand protected areas declines as the protected-area stock rises. At least one study of the Vale do Ribeira region found no measurable gain in vegetation cover or GDP. A BioHub proposing an ecological fiscal transfer must design the performance criteria to reward ongoing restoration outcomes, not static conservation designations.
Municipal currency acceptance faces hard legal limits. Central banks in most jurisdictions have exclusive authority over legal tender. A municipal complementary currency accepted for local taxes operates in a grey zone whose legality depends on the specific wording of the jurisdiction’s central-bank legislation. The South African Reserve Bank Act (Act 90 of 1989) and the National Payment System Act (Act 78 of 1998) are the relevant statutes. Stage 3 requires legal analysis specific to the jurisdiction before any proposal can be advanced.
The FOI gap is itself a finding. The research underlying this entry found that almost no one has filed a formal freedom-of-information request asking a treasury or central bank to describe the accounting treatment of incoming tax receipts. A UK cluster exists on WhatDoTheyKnow; there is no US, South African, Indian, Australian, or Canadian equivalent. Filing such requests (particularly under South Africa’s Promotion of Access to Information Act) would produce primary-source documentation of how the National Revenue Fund actually processes tax receipts at the reserve level, strengthening or weakening the fiscal-space argument that underlies the entire tax-to-commons proposition.

Written September 2026 as a concept-level treatment synthesizing two research documents: Research Instructions: MMT and Tax Revenue Disposal (the commissioning brief) and Research Brief: MMT and Transvestment (the findings). The four legal hooks draw on documented mechanisms across Hungary, Brazil, Portugal, South Africa, and the Wörgl experiment. The synthesized framework (what a BioHub needs to assemble a transvestment policy proposal) and the staging sequence are the wiki’s own constructs, built on the evidence base the research brief assembled. The BioConomy’s distinction from carbon-market approaches is stated as a positioning claim grounded in the BFF’s phased architecture, not as a comparative evaluation of carbon markets.
