Bill 62 amends the Northwest Territories Income Tax Act to incorporate a suite of federal Income Tax Act provisions, remove provisions repealed federally, and bring territorial rules into conformity with the Canada–Northwest Territories Tax Collection Agreement. Key amendments let the territorial government share tax information with Canada, adopt federal rules on returns, assessments, inspections, evidence, and collection procedures, and add references that affect foreign tax credit calculations and COVID‑19 related deductions.
For practitioners and administrators the change matters because it shifts several compliance and enforcement mechanics onto the federally framed rules (with some territorial exceptions), clarifies how split‑income and trust taxation map to territorial rates, and imposes retroactive effective dates for most changes. That combination affects tax computation, assessment risk, interjurisdictional filing, and systems needed for information exchange and collection.
At a Glance
What It Does
The bill incorporates specific federal Income Tax Act sections into the territorial Act (returns, assessments, payments, inspections and evidence), amends local provisions on trusts and split income to read federal percentage references as the territorial “highest percentage,” adjusts references used in foreign tax credit calculations, and authorizes information exchange with Canada.
Who It Affects
Affected parties include NWT taxpayers with multi‑jurisdictional income (including split‑income situations), inter vivos trusts, tax preparers and compliance advisors in the Territories, and the NWT Department of Finance and Minister responsible for tax administration who will implement collection and information‑sharing processes.
Why It Matters
By folding federal procedural and substantive rules into territorial law, the bill reduces certain legal mismatches but creates administrative and compliance effects—notably retroactive application for tax years and an explicit mechanism for intergovernmental information exchange under the Tax Collection Agreement.

What This Bill Actually Does
Bill 62 does three related jobs: (1) it reads selected federal Income Tax Act provisions into the Northwest Territories’ Income Tax Act so territorial taxpayers and administrators rely on the same substantive and procedural rules the federal system uses; (2) it clarifies how certain federal concepts operate in a territorial context (notably taxation of trusts and split income); and (3) it cleans up or removes territorial text that no longer tracks federal law, including temporary COVID‑19 adjustments.
Mechanically, the bill replaces or amends multiple territorial sections to say that named federal sections apply "for the purposes of this Act." That includes provisions on returns and assessments, withholding and payments, amounts receivable and interest, inspection and audit powers, and rules of evidence. Where the bill adopts a federal provision, it sometimes qualifies that adoption—for trusts and split income the bill instructs readers to treat the federal percentage references as the territorial "highest percentage" defined locally.
In one place the bill adjusts which subparagraphs are pulled into territorial law to change how federal paragraph references affect territorial computation (this is the change that touches federal paragraph 110(1) items).On split income and multi‑jurisdictional filers, the bill adopts federal section 120.4 while explicitly directing that the words "Canada" in certain federal definitions are to be read as Canada for purposes of the territorial provision. For inter vivos trusts it adopts federal subsections 122(1) and (2) with the same "highest percentage" reading.
Those textual choices are designed to prevent a territorial GOP (gross‑up/attribution) mismatch when taxpayers have income sourced across jurisdictions.Finally, the bill contains commencement clauses that make most of the Act retroactive to January 1, 2022 (with specified exceptions having other retrospective or later dates). It also inserts a specific application of a federal childcare‑related deduction rule for 2020 and 2021 and removes references to federal provisions that were repealed, so the territorial text no longer points to defunct federal provisions.
Practically, the bill reduces legal inconsistency with federal tax rules but creates implementation work—especially around information sharing protocols, updated forms and guidance, and resolving any disputes that stem from retroactive application.
The Five Things You Need to Know
The bill deems itself to be in force as of January 1, 2022, with specified exceptions: section 4 is retroactive to January 1, 2023, subsection 5(1) to January 1, 2018, subsection 5(2) to July 1, 2021, and sections 7 and 8 to March 25, 2020.
It applies federal subsections 122(1) and (2) (inter vivos trust tax rules) to territorial law but instructs that the percentage in subsection 122(1) be read as the territorial “highest percentage” defined in section 2.1.
It adopts federal section 120.4 on tax on split income, with the percentage in subsection 120.4(2) read as the territorial “highest percentage,” and expressly directs that the word “Canada” in specified federal definitions be read as Canada for territorial purposes.
The Act incorporates a set of federal procedural provisions into territorial law — specifically federal sections and subsections governing returns, assessments, withholding and payment (e.g.
ss. 150–151; 152; 153; 156.1), amounts receivable/payments/interest (e.g.
ss. 158–161), inspections (e.g.
ss. 231–236) and evidence (federal s. 244 subsections listed).
The bill authorizes intergovernmental information sharing and brings the territorial Act into conformity with the Canada–Northwest Territories Tax Collection Agreement, including an amendment to clause 53(2)(b) referencing the Minister acting for NWT and counterparts in provinces or Canada.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Reference update to include section 64.01
This small amendment adds section 64.01 to an existing list of federal sections referenced in a territorial provision. Practically, it ensures that whatever federal rule is now located at 64.01 is treated as part of the territorial computation where that list is used — a housekeeping change that prevents a gap between federal and territorial calculation rules.
Trust taxation: adopt federal subsections with a territorial rate reading
The bill replaces old text with a rule that federal subsections 122(1) and (2) apply to the territorial Act, but it overrides the federal percentage reference so it is read as the territorial “highest percentage” in section 2.1. The practical effect is that trust taxation mechanics from the federal regime (e.g., when tax is payable by an inter vivos trust) apply, while the applicable rate base is explicitly the territorial top rate rather than an automatic federal percentage — avoiding a rate mismatch for territorial assessments.
Split‑income rules incorporate federal section 120.4 with clarifying readings
Territorial law will now use federal s.120.4 to define tax on split income, but again reads the federal percentage reference as the territorial highest rate. The section also resolves cross‑jurisdictional uncertainty by specifying that the word "Canada" in the federal definitions of "source individual" and "specified individual" should be read literally as Canada for territorial purposes — a narrow interpretive rule meant to avoid disputes over which incomes count under the split‑income regime for multi‑jurisdictional filers.
Adjust list of federal paragraph references affecting deductions
The bill alters the enumerated federal paragraph references in clause 3(1)(b)(ii)(C), inserting paragraph 110(1)(e) into the list and adjusting other cross‑references. That change affects which federal subparagraphs are pulled into the territorial calculation, and in context relates to the treatment of certain deductions when computing tax — including a clearer path for how allowed or disallowed deductions factor into the federal foreign tax credit calculation when applying territorial law.
COVID‑19 childcare deduction and related technical updates
The bill renumbers section 3.1, applies federal subsection 63(3.1) specifically to the territorial Act for the 2020 and 2021 taxation years, and expands cross‑references in section 3.5(2) to capture several newly enumerated subsections. These changes explicitly preserve the temporary federal childcare deduction treatment for the indicated years and make sure the territorial cross‑reference list is current with federal amendments made during the pandemic.
Incorporation by reference of federal returns, payments, inspections and evidence rules
The bill replaces several territorial sections to enumerate specific federal provisions that now apply territorially: returns/assessments/withholding/payment rules (s.11 lists federal ss.150–156.1), amounts receivable/payments/interest (s.19 lists ss.70(2), 104(2), 158–161 etc.), inspections and audit powers (s.45 lists ss.231–236), and evidence (s.56 adopts subsections of federal s.244). The approach is selective incorporation rather than wholesale adoption, listing the exact federal sections to be applied and thereby tying territorial procedure to the federal framework for those functions.
Clarifies intergovernmental counterparties for tax administration
This amendment clarifies which officials are the designated counterparts for cooperative functions: the Minister acting for the NWT and either the commissioner or finance minister of an agreeing province, a non‑agreeing province eligible for an adjusting payment, or Canada. That text aligns territorial language with the Tax Collection Agreement and makes clear with whom the Minister can coordinate or share information.
Commencement clauses with retroactive dates
Most of the Act is deemed to be in force January 1, 2022, but the bill specifies different effective dates for particular provisions: section 4 is effective January 1, 2023; subsection 5(1) as of January 1, 2018; subsection 5(2) as of July 1, 2021; and sections 7 and 8 as of March 25, 2020. Those retroactive provisions mean the territorial effects of some changes apply to prior taxation years and could require adjustments to past filings or the reopening of assessments.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Multi‑jurisdictional taxpayers: they gain interpretive clarity on how split‑income and trust rules apply when income crosses federal/territorial boundaries, reducing legal uncertainty about which rates and definitions govern.
- NWT tax administrators (Department of Finance): the Act's incorporation of federal procedures and alignment with the Tax Collection Agreement simplifies collection and assessment processes and creates a clearer legal basis for information sharing with Canada.
- Tax practitioners and compliance advisers in the NWT: adopting federal mechanics means fewer bespoke territorial rules to track and easier alignment between federal and territorial tax advice and tax‑software calculations.
- Taxpayers claiming federal COVID‑19 childcare deductions for 2020–2021: the bill expressly preserves the application of the relevant federal childcare deduction provision for those years, reducing the risk of territorial denial on a technicality.
Who Bears the Cost
- NWT Department of Finance and Minister: they must implement information‑sharing protocols, update systems and forms, and handle the administrative burden of retroactive amendments and potential reassessments.
- Taxpayers with closed tax years: retroactive commencement dates expose some filers to reassessments for years already filed, creating potential surprise liabilities and the need for amended returns or dispute resolution.
- Small tax and accounting firms in the Territories: they will need to update procedures, client advisories and software mappings to align with the newly incorporated federal provisions and territorial rate interpretations.
- Inter vivos trusts and families affected by split‑income rules: because the bill instructs territorial application of the top (“highest”) percentage, some trusts and split‑income taxpayers may face higher tax exposure than under prior ambiguous readings.
Key Issues
The Core Tension
The central dilemma is between harmonization and control: aligning territorial tax law with federal rules and the Tax Collection Agreement simplifies administration and reduces legal mismatch, but it cedes local autonomy and imports retroactive and procedural effects that can increase taxpayer liability and administrative burden without giving the territory independent control over the underlying federal text.
Two implementation risks stand out. First, the bill’s selective incorporation approach keeps territorial law tied to particular federal provisions but also imports federal textual complexity.
That means every future federal amendment to a referenced provision may have unintended territorial effects unless the territorial Act is revisited; the legislature avoided wholesale adoption but still creates a dependency that requires ongoing monitoring and occasional legislative housekeeping.
Second, the retroactive commencement dates invite operational and equity questions. Retroactivity can reopen settled assessments and impose administrative costs on both taxpayers and the NWT tax office.
The deemed‑in‑force dates span 2018 through 2023 for different provisions, so practitioners must map which changes affect which tax years and prepare for potential reassessments and appeals. Information‑sharing authorizations also raise practical privacy and resourcing issues: the NWT must ensure secure channels and clear protocols with federal counterparts before exchanging taxpayer data, and the Department must resource those new responsibilities.
