Bill 6 is an omnibus fiscal statute that folds dozens of Budget 2025 measures into Québec law by amending the Taxation Act and a slate of related statutes and regulations. The changes remap how the province treats several major tax expenditures (notably R&D-related credits and certain resource and e-business incentives), adjusts benefit rules, tightens tobacco identification and vendor controls, and removes a biodiesel fuel refund.
For tax, the bill replaces several existing credits with a redesigned refundable regime for scientific research, experimental development and pre-commercialization; establishes a separate special tax to recover credit amounts in defined circumstances; and inserts structural limits and reporting rules that will drive compliance and cash-flow impacts for recipients. The measure mix matters to corporate tax directors, fund managers, accountants and payroll/benefit officers: it changes claim mechanics, creates new repayment risk, and adds new reporting and timing traps that affect cash flow and eligibility calculations.
At a Glance
What It Does
Implements a new refundable tax-credit regime for scientific research, experimental development and pre-commercialization; establishes a special tax to recover credit amounts in specified refund/repayment scenarios; introduces a new class C share at Capital régional et coopératif Desjardins with subscription and purchaser limits; tightens tobacco retail rules and penalties; and abolishes fuel-tax refunds for biodiesel.
Who It Affects
Québec resident corporations doing R&D (including partnerships and associated groups), eligible public research centres and universities, investors and individual purchasers of Capital régional shares, employers and benefit administrators (family allowance changes), tobacco retail vendors, and biodiesel suppliers/distributors.
Why It Matters
The package restructures major fiscal incentives and adds a built-in recovery mechanism that shifts timing and compliance risk from the government to claimants. That changes how tax departments and finance teams should plan R&D spending, allocate intercompany contracts, manage grant receipts, and report to the Ministère des Finances.

What This Bill Actually Does
Bill 6 recasts how Québec supports business R&D. Instead of a set of disconnected tax credits, the bill creates a new statutory division that deems qualified corporations (and corporate members of qualifying partnerships) to have “paid” amounts to the Minister based on defined categories of eligible R&D and pre-commercialization expenditures.
The deemed payment is calculated through two components: a base refundable percentage applied to eligible scientific research and experimental development spending and a separate percentage that applies to pre-commercialization expenses. The statute sets out detailed rules about which wage costs, contract payments, subcontracting layers and capital expenditures count, and it carves out routine administration, advertising and reimbursed amounts.
It also builds in exclusion thresholds calculated on an employee-by-employee basis so that small‑scale wages can be treated differently from large claims.
To limit fiscal exposure, the bill attaches a cumulative eligible‑expense limit to qualified corporations and partnerships (a balance that moves with prior eligible claims in specified preceding months) and provides allocation mechanics for associated groups. Corporations that are members of an associated group must file an allocation agreement or face Ministerial attribution of that group’s available limit.
The law also requires prescribed forms and very specific vendor/contractor identification data when portions of a payment are being claimed — a practical gate for substantiation and audit.Because the new regime can create up‑front, refundable “deemed payments,” the bill institutes a special tax (a separate Part) to claw back amounts where certain events occur after the refund is effectively crystallized: for example, later repayments of assistance, contract payments received after the filing cut‑off, or where capital items that originally supported an eligible capital claim cease to be used in Québec R&D within defined time windows. The special tax is computed by reference to prior deemed payments and prevents double-dipping while creating a discrete repayment obligation that may fall in a later tax year.Outside the R&D architecture, the bill creates a new class “C” share for Capital régional et coopératif Desjardins, establishes per-capitalization period subscription caps, and limits how much one person may acquire net of prior holdings (mechanics include a $45,000 purchase cap calculation).
For families, the bill preserves a family allowance payment stream for the 12 months after a child’s death and creates a narrowly drafted family-allowance-for-bereaved-parents regime with eligibility, notification and recovery rules. The Tobacco Tax Act now forbids retail vendors from transferring loose tobacco into other containers and imposes a penalty equal to at least $1,000 (or three times the tax that would have been payable).
The Fuel Tax Act removes tax refunds for biodiesel, shifting cost onto biodiesel purchasers or producers when refunds previously reduced fuel tax burden.Across the text the government uses effective‑date layering: many provisions apply retroactively to specific dates referenced in the bill (commonly 25 March 2025 or various dates in 2024–2026). The bill also adds detailed regulation‑making hooks and prescribed‑form requirements that will determine the day‑to‑day compliance burden of the new regimes once the Ministère issues guidance and forms.
The Five Things You Need to Know
The bill creates Division II.4.1.1 in the Taxation Act to establish a new refundable tax-credit framework that deems qualified corporations to have “paid” a tax‑credit amount based on defined categories of scientific research, experimental development and pre‑commercialization spending.
It sets a cumulative eligible‑expense ceiling per qualified entity—$100,000,000 as a rolling balance tied to eligible expenses incurred in prior months—and requires associated groups to file an allocation agreement or accept Ministerial attribution of that ceiling.
To protect the public purse the bill creates a separate special tax (Part III.0.1.2) that requires corporations to repay tax in later years when contract payments, government or non‑government assistance is received after filing dates, or when capital property ceases to be used for Québec R&D within prescribed windows.
Capital régional et coopératif Desjardins may issue a new class “C” automatically redeemable share; subscription is capped by capitalization period amounts and the statute limits how much an individual may acquire (a $45,000‑based per‑person acquisition constraint is embedded in the text).
The bill maintains family allowance payments for the 12 months following a child’s death and establishes a family‑allowance‑for‑bereaved‑parents scheme with notification, payment frequency, and recovery rules; it also bans retail vendors from transferring loose tobacco to other containers and prescribes a minimum penalty of $1,000 or three times the tax evaded.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Extended limitation exceptions for certain GST/QST adjustments
Amends section 25 to allow assessments beyond the usual limitation where an assessment solely concerns an amount payable under the federal Excise Tax Act (section 218.01) or specific Québec sales tax provisions; the change is given retroactive effect to August 4, 2023. Practically this expands the window for reassessments tied to indirect tax adjustments and interacts with federal excise-based reassessments.
New class C shares, subscription caps and purchaser limits
Adds class “C” shares automatically redeemable after a fixed term and authorizes subscription limits per capitalization period (graded amounts from $150M to $170M across 2025–2030 capitalization periods). It also inserts a purchaser‑limit rule that restricts acquisition by an individual to the amount by which $45,000 exceeds the aggregate of prior qualifying purchases (with narrow exceptions for succession, prior redemptions and certain policy buybacks). The practical effect: a controlled rollout of new equity with built-in anti‑arbitrage limits and capital‑raising cadence tied to fiscal-year windows.
New refundable credit for SR&ED and pre‑commercialization
Creates a detailed new framework that (1) defines eligible scientific research, experimental development and pre‑commercialization activities; (2) specifies which wages, contract payments (including second‑tier subcontracting rules) and capital costs qualify; (3) sets explicit exclusions (administration, advertising, reimbursed costs); and (4) provides employee‑by‑employee exclusion thresholds. The division also prescribes the documentation and reporting forms required for deemed payment treatment, turning many formerly retrospective non‑refundable calculations into up‑front refundable positions subject to verification.
Cumulative eligible‑expense limit and associated‑group allocation rules
Establishes a $100,000,000 baseline balance concept (computed with reference to eligible expenses in prior months/fiscal periods) that limits the portion of eligible spending that can get the enhanced tax treatment. Where corporations form an associated group they must file an agreement allocating the group’s available limit; absent a timely agreement the Minister will attribute amounts among group members. That allocation mechanism creates competitive pressure within groups and requires coordination among related entities.
Recordkeeping, prescribed forms, and the new special tax to recover credits
The bill requires prescribed forms and specific supplier/contractor identification (including QST registration numbers and, in some cases, Social Insurance Numbers for individuals) when claiming portions of contract‑based expenditures. It also creates Part III.0.1.2, a special tax that triggers when assistance is repaid, contract payments arrive late, or eligible capital ceases being used for Québec R&D during statutory windows—forcing post‑claim reconciliations and potential later tax liabilities.
Maintenance of family allowance after a child’s death; new bereaved‑parents rules
Inserts a subdivision that keeps a family allowance payable to an entitled individual for each month of the child’s minority that falls within the 12 months after the month of the child’s death, subject to exclusions (e.g., an individual convicted of attempting on the child’s life). It also sets notification obligations, payment frequency, replacement claims when spousal situations change, and recovery mechanisms for overpayments—operational details Retraite Québec will follow through forms and notices.
Loose‑tobacco handling ban and strict penalties
Adds a prohibition on retail vendors transferring loose tobacco from its packaging to any other container, with a penalty equal to the greater of $1,000 and three times the tax that would have been payable. This is a compliance‑focused rule designed to curb product diversion and tax evasion at the retail point of sale; it will require changes to retail practices and enforcement protocols.
Abolition of biodiesel refunds
Eliminates tax refunds that were previously available for biodiesel fuel acquired after 25 March 2025. That change moves cost onto biodiesel purchasers or suppliers and can alter the economic competitiveness and supply pricing of biodiesel relative to other fuels.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Québec-based R&D performing corporations — the new refundable structure can accelerate access to cash because eligible corporations will be deemed to have paid amounts to the Minister (refundable), improving near‑term cash flow for qualifying R&D and pre‑commercialization expenditures.
- Eligible public research centres and eligible university entities — the statute retains and refines linkage routes (university research contracts, eligible research consortia) so public research partners can be part of the eligible‑spend chain and benefit indirectly through contracted work.
- Investors and first purchasers of Capital régional class C shares — the new share class and tax credit tied to initial purchase create a new, limited channel for retail‑style tax‑assisted investment in a regional cooperative vehicle, subject to per‑cap period caps.
- Bereaved families — the family‑allowance maintenance rules ensure continued monthly support for up to 12 months after a child’s death, providing short‑term income continuity subject to eligibility and notification requirements.
- Tax and compliance advisers — the bill creates many new reporting obligations, prescribed forms and substantive interpretive questions, increasing demand for professional tax compliance, audit defense and structuring work.
Who Bears the Cost
- Corporations that claim the new R&D credits — they face new post‑claim repayment risk under the special tax if assistance is later repaid, if contract payments arrive late, or if eligible capital stops being used in Québec, which can create cash‑flow volatility and contingent liabilities.
- Associated corporate groups — they must negotiate and file allocation agreements for the $100M‑style limits; absent agreement the Minister will attribute amounts, potentially disadvantaging particular affiliates and requiring governance coordination.
- Biodiesel producers/distributors and purchasers — abolition of biodiesel refunds increases net tax costs on biodiesel, compressing margins or increasing retail prices depending on who absorbs the change.
- Tobacco retailers — the ban on transferring loose tobacco and the substantial penalty attach new compliance obligations and downside risk for everyday retail handling practices.
- Ministère des Finances / Retraite Québec — significant new administrative workload: issuing prescribed forms, processing deemed payments and special‑tax computations, auditing reports, and adjudicating recovery claims without matched incremental appropriation increases will strain implementation capacity.
Key Issues
The Core Tension
The bill tries to make Québec simultaneously more generous and more fiscally controlled: it offers faster refundable support for R&D while inserting tight caps and a recovery tax that transfer the government’s fiscal risk back to claimants. That trade‑off encourages investment but increases complexity, compliance cost and contingent liability for firms — a design that benefits well‑resourced taxpayers who can manage reporting and cash‑flow risk and complicates access for smaller, less administratively capable claimants.
The bill combines two policy intents that pull in opposite directions: (1) to stimulate private R&D and product pre‑commercialization through refundable, up‑front credit mechanics that improve immediate cash flow; and (2) to protect fiscal integrity via strict exclusion rules, a $100M cumulative eligible‑expense cap and a special tax that claws back amounts when later assistance or contract payments change the net public support picture. That design narrows abuse vectors but creates real operational complexity: the deemed‑payment model depends on precise supplier identification, multi‑tier subcontractor tracing, and timely disclosure of later receipts (contract payments, grants, reimbursements).
Firms will need stronger contract drafting, flow‑through of QST registration numbers and new internal processes to collect second‑tier subcontractor SINs/IDs for prescribed forms.
The recovery (special tax) regime introduces timing risk: tax departments must now plan for potential liabilities that can materialize years after the original claim if, for example, a third party receives assistance or a capital asset ceases Québec R&D use. That creates a cash‑management burden and may discourage certain capital investments or subcontracting chains that previously were routine.
The associated‑group allocation rule can lead to intra‑group bargaining, end‑of‑year income‑shifting to preserve an entity’s balance of eligible limit, and disputes if the Minister attributes amounts. Finally, changes that touch extensive legacy regimes (flow‑through shares, resource deductions, e‑business credits) create transitional traps: effective dates are layered and retroactive in places, so taxpayers must map which past claims remain valid and which are curtailed by the new rules.
