Source Verification Report: June 2026
Last verified: Effective for 2026 tax year by Fiscal Moose
This is our first public source-verification report. It records what we checked across all eight calculators for the 2026 tax year, the official sources behind each figure, what changed since the data was first entered, and what did not. Every value cited here is read from the same versioned data files the live calculators use, so this report cannot quietly drift from the tools it describes.
What "verification" means here. Fiscal Moose verifies calculator data against public official sources and tests formulas against documented reference cases. This is not CPA review, legal review, or professional financial advice, and it is not an audit in the regulated accounting sense, it is our own source-checking and formula testing. The calculators are estimates; see the disclaimer.
Calculators covered
All eight: the First Home Savings Account (FHSA), Tax-Free Savings Account (TFSA), Registered Retirement Savings Plan (RRSP), Mortgage Payment, Mortgage Affordability, Income Tax, Salary / Take-Home Pay, and Capital Gains calculators.
Source families checked
- Canada Revenue Agency (CRA): federal tax brackets and the Basic Personal Amount and its high-income phase-out, FHSA / TFSA / RRSP contribution limits, the Home Buyers' Plan limit, CPP / CPP2 / EI rates and ceilings (see the salary / take-home calculator), and the capital gains inclusion rate.
- Provincial and territorial finance ministries: the twelve non-Quebec provincial / territorial tax brackets, basic personal amounts, and the Ontario surtax and Ontario Health Premium, all consumed by the income tax calculator.
- Canada Mortgage and Housing Corporation (CMHC): mortgage default-insurance premium tiers, the maximum insurable loan-to-value, and the extended-amortization surcharge, used by the mortgage payment calculator and the mortgage affordability calculator.
- Bank of Canada: the policy interest rate that feeds our rate-sensitive mortgage tooling.
- Statistics Canada: the New Housing Price Index by province, shown on the FHSA calculator as illustrative context, not as a calculator input.
What we confirmed for 2026
The figures below were re-read against their primary sources during this verification pass. They are the values the calculators currently use.
| Figure | 2026 value | Primary source | Calculator |
|---|---|---|---|
| FHSA annual contribution limit | $8,000 | Canada Revenue Agency | FHSA calculator |
| FHSA lifetime limit | $40,000 | Canada Revenue Agency | FHSA calculator |
| Home Buyers' Plan limit (separate program) | $60,000 | Canada Revenue Agency (Budget 2024) | RRSP calculator |
| CPP first earnings ceiling (YMPE) | $74,600 | Canada Revenue Agency | Salary calculator |
| CPP2 second earnings ceiling (YAMPE) | $85,000 | Canada Revenue Agency | Salary calculator |
| Maximum insurable loan-to-value (CMHC) | 95% | Canada Mortgage and Housing Corporation | Mortgage payment calculator |
| Capital gains inclusion rate | 50% (flat) | Canada Revenue Agency | Capital gains calculator |
What changed, and what did not
Confirmed unchanged for 2026. The CPP / CPP2 / EI rates and ceilings, the FHSA and TFSA / RRSP contribution limits, the federal Basic Personal Amount phase-out band, and the CMHC premium tiers all matched the values already in our data files. No calculator formula changed as a result of this pass.
The figure we watch most closely. The capital gains inclusion rate remains a flat 50% for 2026. The 2024 federal-budget proposal to raise it to two-thirds on gains above $250,000 was deferred and then formally cancelled on 21 March 2025; we re-confirmed during this pass that no later change has reinstated it. Our Capital Gains calculator applies the flat 50% rate with no $250,000 threshold.
A distinction we keep deliberately. The FHSA and the Home Buyers' Plan (part of our RRSP calculator) are separate programs and we never merge them into a single "combined" figure. An FHSA qualifying withdrawal is tax-free and is not repaid; an HBP withdrawal comes from your RRSP and is generally repaid over fifteen years. The two can be used together for the same first-home purchase, but they are not the same kind of money, and our tooling reports them as separate outputs. See the FHSA methodology page for the full treatment.
Formula testing
Beyond confirming the input data, every calculator is tested against a reference suite: documented scenarios with known expected outputs, drawn from CRA worked examples and primary-source calculations. Lower-risk tools carry at least ten cases; the bracket-engine tools (Income Tax, Salary, Capital Gains) carry at least thirty each. The build fails if any case diverges from its expected value by more than one percent. Selected calculations also have independent verifier scripts on a separate code path, where practical; for some tools that second check covers the projection or amortization specifically, with the core room and limit mechanics covered by the reference cases. The methodology page documents the full process.
Known unresolved gaps
We are explicit about what these calculators do not yet cover. The most significant open gaps are Quebec (not yet modelled), capital losses and carry-forward, the Lifetime Capital Gains Exemption, and the Alternative Minimum Tax. The full list, with the specific scope of each tool, is in the known-limitations section below and on each calculator's own page. These are tracked and addressed in future verification passes.
Next scheduled verification
The next routine pass is the January 2026 → 2027 indexation window: CRA indexation factors, new contribution limits, and the January edition of the CRA T4127 payroll formulas, followed by the provincial-budget window in the spring. Any off-schedule change, a Bank of Canada rate decision or a mid-year tax change, is applied sooner and recorded on the changelog.
Primary sources verified in this report
Known limitations
- This report covers the 2026 tax year only. Earlier years are documented in their own year-specific data files; this report does not restate them.
- Quebec is not yet modelled. Our calculators cover the federal layer and the twelve non-Quebec provinces and territories; the Revenu Québec engine (provincial brackets, the federal abatement, QPP/QPIP) is verified separately and is not part of this report.
- Verification means source-checking against official publications and formula testing against documented reference cases. It is not CPA review, not legal review, and not professional financial advice. No figure in this report has been reviewed by an accountant or lawyer.
- The Statistics Canada New Housing Price Index is included as context only; it is not an input to any calculator result.
- Some advanced cases are intentionally out of scope and tracked as known gaps: capital losses and carry-forward, the Lifetime Capital Gains Exemption, the Alternative Minimum Tax, and non-employment income types. Each calculator’s own page lists its specific limitations.
