Bill 21 amends Prince Edward Island’s Income Tax Act to increase individual tax relief and lower the general corporate rate. It raises the basic personal amount and related spouse/dependent amounts in two steps (with different figures effective January 1, 2025 and January 1, 2026), lifts low-income tax reduction thresholds, updates individual tax-bracket thresholds, and reduces the general provincial corporate tax rate from 16% to 15% effective July 1, 2025.
The bill also replaces the provincial small business deduction calculation with a new formula that uses a deemed federal business limit of $600,000 for provincial purposes, adds transitional rules for taxation years that straddle July 1, 2025, clarifies the application of several provisions to credit unions, and adjusts the foreign tax credit to align with the lower general rate. The package changes both taxpayer liabilities and compliance complexity for accountants, corporate tax departments, and the provincial tax authority.
At a Glance
What It Does
It resets the individual bracket thresholds and raises the basic personal exemption in two stages, reduces the general corporate rate from 16% to 15% on July 1, 2025, and implements a new two-part formula for the small business deduction that applies a 1.0% rate to the business-limit portion and 15% to the remainder. The bill also deems the federal business limit to be $600,000 for provincial calculations and creates notional-year rules for split taxation years.
Who It Affects
Individuals with low-to-moderate incomes (due to higher personal exemptions and higher low-income reduction thresholds), provincially taxable corporations including CCPCs and credit unions (because of rate and small-business-deduction changes), accountants and tax departments preparing split-year calculations, and the provincial treasury which will see lower revenue per dollar of taxable income.
Why It Matters
The measure shifts after-tax income toward individuals and small businesses while reducing the province’s headline corporate rate; it also introduces new cross-jurisdictional calculations (C/D apportionment and a deemed federal limit) that create compliance and administration issues not present under the previous, simpler rules.

What This Bill Actually Does
The bill rewrites how PEI calculates both individual and corporate provincial income tax. For individuals, it replaces the existing rate table and raises the income thresholds that determine which marginal rate applies; it separately increases the basic personal amount and spouse/dependent credit in two stages so that one set of increased figures applies for 2025 and a larger set applies for 2026.
The low-income tax reduction threshold is adjusted upward in the same two-step pattern. Those changes reduce taxable income subject to each bracket and raise the income level at which benefits phase out.
On the corporate side, the bill lowers the province’s general corporate rate to 15% beginning July 1, 2025. More substantively, it creates a new provincial small business deduction formula for taxation years starting on or after July 1, 2025: the province will tax the portion of in‑province taxable income that corresponds to the federal business limit at a 1.0% rate and tax the remainder at 15%.
To do that it multiplies the federal business-limit amount by the corporation’s in‑province share of taxable income (the C/D ratio) so that the business-limit portion is pro-rated by provincial activity.Because many corporations have taxation years that cross July 1, 2025, the bill requires those years to be split into two notional taxation years: apply the old small-business rules to the pre‑July 1 portion and the new formula to the post‑July 1 portion, apportioning taxable income by days. The bill also expressly treats credit unions as within the scope of certain small-business-related subsections (removing a prior textual exclusion), amends a number of cross-references to prevent double taxation of deposit insurance corporations, and lowers the foreign tax credit rate to match the new 15% general rate.
Several sections come into force on different dates—some retroactive to Jan. 1, 2025, some on July 1, 2025, and others on assent—which creates layered transition rules practitioners must follow.
The Five Things You Need to Know
The individual tax-bracket schedule is rewritten: rates remain progressive but apply to new thresholds, with the lowest rate at 9.50% up to $33,928 and the top provincial rate at 19.00% above $142,520 for taxation years 2026 onward.
The basic personal amount and spouse/dependent credits increase in two steps: amounts set for Jan. 1, 2025 ($14,650 base) and larger amounts for Jan. 1, 2026 ($15,000 base), changing both the base credit and the income-tested phase-outs.
The province reduces its general corporate tax rate from 16% to 15% effective July 1, 2025 and simultaneously revises the provincial small business deduction using the formula (A×B×C/D) + (E×(C – (B×C/D))) where A=1.0% and E=15%.
For provincial purposes the bill deems the federal business limit used under section 125 of the federal Income Tax Act to be $600,000 when calculating the provincial small business deduction.
Taxation years that straddle July 1, 2025 must be split into two notional years, apportioning taxable income by days and applying the old rules to the pre‑July 1 portion and the new corporate rate and small-business formula to the post‑July 1 portion.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
New individual rate table and thresholds
Section 1 replaces the existing computation for tax payable by individuals and supplies a five‑bracket schedule with explicit cutpoints and marginal rates (9.50% up to $33,928; 13.47% on the next slice; 16.60%; 17.62%; and 19.00% above $142,520). Practically, taxpayers and payroll systems need to apply the new breakpoints to taxable income computations beginning in the 2026 taxation year; the structure preserves marginal progression but shifts where income falls between brackets.
Two-step increase to basic personal and dependent credits
This section substitutes new figures for the basic personal amount and related spouse/dependent calculations in two subsections: one set of increases is treated as effective Jan. 1, 2025, and a larger set comes into force Jan. 1, 2026. The amendment retains the existing A×B mechanism (applying an appropriate provincial percentage to a dollar base) but raises the dollar bases and the income-tested phase-out formulas. Practitioners must implement the correct figures by tax year and ensure spouse/dependent phase-outs use the updated thresholds for each period.
Raise to low-income tax reduction threshold
Two incremental edits increase the income threshold that triggers the provincial low-income tax reduction: first to $22,650 and then to $23,000. The change affects eligibility and the tapering of the reduction in 2025 and 2026 respectively, so advisers should check reduction calculations for low-income filers across those years.
Corporate general rate cut and matching foreign tax credit adjustment
Section 4 lowers the provincial general corporate rate from 16% to 15% effective July 1, 2025. Section 11 updates the foreign tax credit rule to 15% so that the credit’s provincial component aligns with the new general rate. Corporations, particularly those with foreign income, must factor the lower provincial rate into tax provisioning and foreign tax credit computations for periods on or after July 1, 2025.
Credit unions included and deposit-insurance cross-references fixed
Multiple small edits remove language that previously excluded credit unions from certain subsections and add cross-references to ensure deposit insurance corporations are not taxed twice. The net effect is legal clarity: credit unions are explicitly within the relevant small-business/deduction framework and the statute’s cross-references now prevent overlapping taxation for deposit insurers—an important drafting cleanup for financial institutions and administrators.
New provincial small business deduction formula and deemed federal limit
This is the bill’s most technical change: it prescribes a formula that taxes the portion of PEI taxable income corresponding to the federal business limit at a 1.0% rate and the remainder at 15%. The provision also directs that, for this purpose, the corporation’s business limit under federal section 125 be treated as $600,000. Because the calculation uses the corporation’s in‑province taxable income (C) and total provincial taxable income (D) in a C/D apportionment, companies with multi‑province activity will need to compute accurate in‑province allocations.
Staggered effective dates and notional-year transition for straddling tax years
The bill stages commencement: some amendments are deemed effective Jan. 1, 2025; others on Jan. 1, 2026; several on July 1, 2025; and some come into force on assent. Critically, for corporations whose taxation year straddles July 1, 2025, the Act requires dividing the year into two notional taxation years, apportioning income by days, and applying the old rules to the first notional year and the new rules to the second—adding calculation steps and records retention obligations for affected taxpayers.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Low- and middle-income individuals: Higher basic personal amounts and raised low-income reduction thresholds increase non‑taxable income and reduce provincial taxes for many filers.
- Small businesses operating primarily in PEI (CCPCs): The new small-business formula applies a 1.0% rate to the business-limit portion of in‑province income and uses an elevated $600,000 business limit, reducing provincial tax on the first slice of income.
- Corporations with taxable years entirely after July 1, 2025: All such corporations benefit from the headline corporate-rate reduction from 16% to 15%, lowering statutory provincial tax on residual income.
- Credit unions and deposit-insurance corporations: The clarifying amendments remove prior textual exclusions and revise cross-references, reducing legal uncertainty about how these entities are taxed under the small-business and deposit-insurance rules.
Who Bears the Cost
- Provincial treasury: Lower corporate and individual effective tax take will reduce revenue per dollar of taxable income and may create pressure on budgets or require offsetting measures.
- Multi‑jurisdictional corporations and tax preparers: The C/D apportionment and deemed federal business-limit rule increase calculation complexity and documentation burdens, particularly for firms with operations in multiple provinces.
- Small employers and accountants: Implementing split‑year notional calculations for corporations with tax years straddling July 1, 2025 imposes additional year‑end work and potential systems changes.
- Tax administration (PEI Revenue): Administering the new small-business formula, the deemed federal limit, and reconciling provincial/federal interactions will require guidance, systems updates, and potentially more audit resources.
Key Issues
The Core Tension
The central dilemma is between targeted tax relief and administrative simplicity: the government lowers rates and boosts credits to shift after‑tax income to individuals and small businesses, but it does so by introducing pro‑rata formulas, deemed federal limits, and notional-year splits that increase compliance costs, create cross-jurisdictional mismatch risk, and demand significant administrative guidance to avoid unfair or inconsistent outcomes.
The bill balances tax relief against administrative complexity. The new small-business deduction uses a pro‑rata approach (C/D) tied to in‑province taxable income, which is conceptually clear but operationally tricky: multinational or multi‑province groups will need consistent, defensible allocation rules for C and D, and mismatches between federal and provincial definitions of taxable income could produce unexpected results.
Deeming the federal business limit to $600,000 for provincial calculations may diverge from the federal reality if Ottawa changes its associated or indexed amounts, creating a recurring reconciliation headache.
The notional‑year split for taxation years that straddle July 1, 2025 reduces arbitrary outcomes but forces taxpayers to run parallel computations and pro‑rations, increasing professional fees and the potential for bookkeeping errors. The change to include credit unions explicitly in certain provisions removes a drafting ambiguity but may change their effective tax exposure depending on how the underlying subsections operate.
Finally, lowering the foreign tax credit to match the provincial rate simplifies rate parity but increases the risk of residual double taxation where federal credits and provincial calculations interact unfavorably. The statute leaves open several implementation details—particularly precise rules for apportioning C and D, interaction with affiliated/associated business limit rules, and the handling of refunds or carryovers spanning the effective dates—that will require administrative guidance or regulation.
