Alberta already collects tax. Tax and Revenue Administration assesses and collects Alberta's corporate income tax today — Alberta is one of only two provinces that administers its own, with Quebec — and it operates the fuel tax, tobacco tax and tourism levy on the same platform. The transition uses that platform rather than replacing it.
The design principle is fewer taxes at rates set to the requirement, rather than many taxes each with its own administration. Personal income tax is added to a system that already runs corporate tax on the same taxpayer base. The costing runs a scenario with a sales tax at five per cent on the existing federal base. The rate and the base are for the Legislative Assembly to set; what is costed here is the administration behind them, which runs on the same registrants, the same filing periods and the same rules that businesses already comply with — Alberta changes who receives the return, not what is on it. A number of instruments are treated as zero-rated or ceasing in this costing scenario: customs duty, excise, and capital gains among them. Removing an instrument removes the staff, systems and audit capability behind it, so simplification reduces the size of the revenue authority rather than merely the number of forms.
What this domain does not do is build a new tax system. It processes broadly the same volume of returns it processes today, from broadly the same filers, with larger numbers on them. The added cost is the personal income tax and sales tax functions and the collections, audit and appeals capacity they require, net of what Alberta already funds and net of the instruments that fall away.

How the figure is built
C$316.2M a year of added running cost and C$447.4M one-time, of which C$112.0M is capital. Alberta already administers its own corporate income tax through Tax and Revenue Administration, one of only two provinces that does, with Quebec, and runs its own treasury and tax policy. The full cost of a revenue authority is C$475.5M against a complement of 1,750; about C$159.3M of that is already funded in the provincial budget. What independence adds is personal income tax assessment, which the Canada Revenue Agency performs today at no charge to Alberta, and a sales tax administration Alberta has never operated.
The lines
| C$M | ||
|---|---|---|
| Full cost of the revenue authority | 475.5 | 1,750 permanent posts at a C$156,000 loaded rate, being C$273.0M, plus C$202.5M operating |
| less already funded in the provincial budget | -159.3 | About 562 posts: corporate tax assessment and audit, tax policy, TRACS and treasury operations, and the administration of Alberta's own standing levies. With 1,188 new posts this ties to the 1,750 complement |
| ADDED RUNNING COST, a year | 316.2 | |
| Consumption tax receipt and assessment | 28.0 | The existing 5% tax continued under Alberta law; registrants, rate, base and filing rhythm unchanged |
| Personal income tax assessment and withholding reconciliation | 38.0 | The one capability Alberta genuinely lacks. Simplified returns, no separate capital gains computation |
| Taxpayer identity and account extension | 18.0 | Extends TRACS, which already runs assessment, objections, audit and collections |
| Data exchange and treaty interfaces | 14.0 | Information exchange with Canada and treaty partners |
| Security operations | 14.0 | A revenue authority is a standing target |
| Capital | 112.0 | |
| Registrant and account transfer | 32.0 | About 400,000 registrants re-point remittance rather than registering for a tax that did not exist |
| Payroll withholding transition | 45.0 | Every employer changes remittance destination and method |
| Data acquisition and reconstruction | 48.0 | Taxpayer records held by the Canada Revenue Agency; the largest irreducible line |
| Parallel running and rehearsal | 36.0 | A full tax year run in shadow before Day 1 |
| Legal authority, legislation and regulation | 26.0 | A tax statute book. Quebec's Taxation Act is the precedent |
| Programme management and assurance | 34.0 | 24-month stand-up |
| Contingency at 15% | 58.4 | |
| ONE-TIME TOTAL | 447.4 |

The complement for this domain is carried at domain level. A function-by-function split has not been established, and none is shown rather than one being constructed for presentation.
Comparators
| Figure | ||
|---|---|---|
| Singapore, Inland Revenue Authority | 1,382 staff, 23.4 per 100,000 | Pure tax authority in a city-state with high automation. The efficient floor |
| New Zealand, Inland Revenue | 3,923 staff, 55.0 per 100,000 once social policy delivery is stripped | Also delivers Working for Families, child support, student loans and KiwiSaver |
| Ireland, Revenue Commissioners | 6,843 staff, 93.0 per 100,000 once customs is stripped | Also runs customs and excise, which Alberta carries at Border and Customs |
| Quebec, Revenu Quebec | about 11,000 staff, 86.5 per 100,000 once benefit delivery is stripped | The only sub-national government running its own complete personal income tax, and the precedent that it can be done. Also administers QST and collects the federal GST. The headcount is an order-of-magnitude figure rather than a published complement, so the comparison with Alberta is indicative of scale and not of a precise ratio |
| Alberta, proposed | 1,750 posts, 35.8 per 100,000, on three taxes | The narrowest instrument set of any comparator, at 1.53 times Singapore's staffing per head. Adequately provided rather than lean |
What these figures assume
- The costing runs a scenario in which withholding at source is treated as final for taxpayers with straightforward employment income, so that most Albertans never file a return that has to be assessed. Return volume rather than rate complexity drives headcount in a revenue authority, and this single design choice - which is the Legislative Assembly's to make - carries the estimate. If it is not adopted the complement moves toward the comparator midpoint of about 2,695 posts and the annual requirement rises to about C$622.9M. This is a costing scenario rather than a recommendation: the report prices a tax design, it does not propose one.
- The existing five per cent consumption tax is continued under Alberta law rather than replaced by a new retail sales tax. Registrants, rate, base and filing rhythm are unchanged; what changes is which government receives the return. Return volume does not rise.
- Alberta continues to administer corporate income tax through Tax and Revenue Administration, which already runs assessment, objections, audit and collections through TRACS. Independence adds personal income tax assessment, which is the one capability Alberta genuinely lacks.
- Alberta's own standing levies continue unchanged. The fuel tax, tobacco tax, tourism levy, insurance premiums tax, freehold mineral rights tax and liquor mark-up are provincial today, are collected and retained by Alberta today, and independence changes nothing about them. The roughly 62 posts that administer them on the existing platform are existing provincial staff inside the complement, not an addition to it. The no-rebates rule governs rebates and the consumption tax; it does not zero Alberta's own levies, which continue. Capital gains is assumed paused rather than repealed, so the statute retains the charge and the computation is suspended for the transition. Whether it resumes, and on what terms, is a decision for the Legislative Assembly
- The existing complement of about 600 posts is estimated by capability. Tax and Revenue Administration is a division inside Treasury Board and Finance and is not separately published in Budget 2026.
- Existing platforms extend rather than being replaced. A major systems integrator is not engaged, as the supporting analysis recommends.
- This domain states no revenue and supports no net fiscal position. It is the cost of administering taxes, not a forecast of what they raise.
How this connects to other domains
Employment Insurance premiums of about C$3,700M and Alberta Pension Plan contributions of about C$11,900M are collected here and costed against Social Programs Continuity and Pensions and Public Payments respectively. Customs duties are collected at the border and sit with Border and Customs. The foreign tax credit design that determines who bears non-resident withholding on pensions is owned here and is dependent on negotiations with Canada.
