EverStone prepares the T2 and the Alberta AT1 together for incorporated contractors and owner-run companies in Fort McMurray and the rest of Wood Buffalo, working fully online.

[Get My Fixed Quote](https://www.everstonecpa.com/book-online)[Ask a Free Question](https://www.everstonecpa.com/quick-question) **Quick answer:** Alberta administers its own corporate income tax, so a Fort McMurray corporation files a federal T2 with the CRA and a separate AT1 with Alberta Tax and Revenue Administration. EverStone prepares both from one closed year end, remotely. For a one-owner trades corporation, bookkeeping, payroll and the year-end T2 together usually run $450–$650 a month. One-owner Fort McMurray corporations: bookkeeping, payroll and the T2 from $450 to $650 a month. Filings: the T2, Schedule 1, Schedule 50, the CCA schedule, the small business deduction, T4 or T5 slips, the AT1 and instalments. ## Two corporate returns, not one Most Canadian provinces let the CRA collect their corporate income tax, so a single T2 carries both layers. Alberta does not. A corporation with a permanent establishment in Alberta files the federal T2 with the CRA *and* the AT1 with Alberta Tax and Revenue Administration. The two draw on the same trial balance, but they are separate filings with separate accounts, separate correspondence and separate ways to fall behind. That matters more in Fort McMurray than in most Alberta cities, because so many corporations here were set up somewhere else. A contractor who incorporated in British Columbia or Ontario, then moved north for the work, can spend years filing only the federal return without realising that a permanent establishment in Alberta brought an AT1 obligation with it. The gap usually surfaces as provincial correspondence long after the federal return was accepted. Preparing both returns together, from one closed year end, is the only arrangement that keeps the two sets of figures reconciled and the provincial account current. ## What Alberta’s rates mean for a Wood Buffalo corporation Active business income eligible for the [small business deduction](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/t4012.html) is taxed at a combined 11% in Alberta — 9% federal plus 2% provincial — on a $500,000 business limit shared across any associated group. Income above that limit, or income that does not qualify, is taxed at 23% combined: 15% federal plus Alberta’s 8% general rate, the lowest provincial general rate in Canada. For a site-services company coming off a heavy turnaround season, the business limit is a real planning number rather than a theoretical one. Income that stays under it inside the corporation is taxed at 11%. Profit pulled out as salary is deducted by the corporation and taxed personally instead. The decision about how much to leave in the company is worth making with both corporate rates and the owner’s personal position in front of you, before the year end closes and the options narrow. Where the owner also holds a second corporation — an equipment company leasing units to the operating company, for instance — the two are usually associated and share one $500,000 limit, which is easy to miss when each company’s return is prepared in isolation. ## Equipment, CCA and the return A typical Fort McMurray contractor’s balance sheet carries more equipment than a city services company of the same size: pickups and crew trucks, trailers, loaders, pressure-washing or vac units, light towers, shop tools and the odd sea can. Each asset sits in a [capital cost allowance class](https://www.everstonecpa.com/blog/capital-cost-allowance-cca-classes-canada) with its own rate, and the class decides how fast the cost comes off taxable income. Getting the class wrong does not cause a penalty on its own, but it puts the wrong number in every year that follows. Two points come up repeatedly. First, the year an asset becomes available for use governs the claim, so a unit ordered in November and delivered in January belongs to the next year regardless of when it was paid for. Second, trade-ins are disposals. When a well-maintained truck is traded against a new one, the trade-in value is proceeds of disposition, and if the class has been depreciated faster than the truck actually lost value, the difference comes back into income as recapture. Tracking each unit from purchase to disposal is what keeps the CCA schedule honest and the year end free of surprises. ## One-client corporations and personal services business risk Wood Buffalo has a large number of one-person corporations supplying a single skill to a single operator or prime contractor: an inspector, a safety advisor, a planner, a millwright or an electrician who incorporated because the client preferred to pay a company. That structure is legitimate, but it attracts a specific corporate tax risk. If the CRA concludes the corporation is a [personal services business](https://www.everstonecpa.com/blog/personal-services-business-psb-risk-canada), the small business deduction is denied, the general federal rate applies with an additional surtax, and almost every ordinary business deduction is disallowed. The determination turns on the same control, tools, subcontracting and risk factors used to separate employees from contractors. A corporation with one client, a site badge issued by that client, the client’s schedule, the client’s tools and no ability to send someone else is the profile that draws attention. It is worth reviewing before the return is filed, and worth revisiting whenever the contract changes, rather than after an assessment arrives. ## Instalments run on two schedules Once a Fort McMurray corporation has tax payable above the threshold that triggers [instalments](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/corporations/corporation-payments/paying-instalments.html), it pays two governments. One stream goes to the CRA for federal tax, the other to Alberta Tax and Revenue Administration for the provincial share. Two streams mean two ways to fall short, and interest accrues on each independently. The instalment base is usually built from prior-year figures, which is where Wood Buffalo files go wrong. A company coming off a year with a major shutdown keeps paying at that level into a year with less work, unless the estimate is revised deliberately. Basing instalments on the current year’s estimate helps in a slow year, but if the estimate proves too low, interest runs on the shortfall. That judgement deserves a look every year against the work actually booked. [How corporate instalments work](https://www.everstonecpa.com/blog/corporate-tax-installments-canada) sets out the methods. ## Choosing a year end that suits the work A fiscal year end is chosen once and changed only with permission, so it is worth choosing against how the business actually earns. For many Wood Buffalo contractors the busiest periods fall around spring and autumn maintenance seasons. A year end in the middle of one lands the close in the busiest weeks, with half-finished work orders and unbilled time on the balance sheet. A year end in a quieter month gives cleaner work-in-progress and receivables figures, leaves room to decide on bonuses before the deduction deadline, and keeps the corporate filing away from personal tax season. [Choosing a fiscal year end](https://www.everstonecpa.com/blog/corporate-fiscal-year-end-canada-how-to-choose) works through the trade-offs. ## Working outside Alberta Some Fort McMurray corporations send crews to jobs in Saskatchewan or British Columbia between local seasons. Once a corporation has a permanent establishment in more than one province, its taxable income is allocated among them, and that allocation decides which provincial rate applies to which share. A crew on an extended job outside Alberta is a tax fact, not only a scheduling one, and it is far easier to record during the year than to reconstruct from timesheets afterwards. Sales tax follows the same logic: work performed in another province can carry that province’s tax, not 5% GST. ## How the engagement runs online EverStone is a fully virtual, one-CPA firm. There is no Fort McMurray office, no branch and no local staff. The work is done remotely: records arrive through secure upload, questions are answered by email so you can deal with them between shifts, and both returns are e-signed and transmitted electronically. The T2 and the AT1 are prepared to the same rules wherever the preparer sits. What matters is that the CPA who reviews the year-end figures is the one who files them, and that the same person is there when the CRA or Alberta writes. Authorization runs through your CRA My Business Account, so notices and balances can be checked directly. Year-end planning only works against a number you set earlier, which means [the budget behind the planning](https://www.everstonecpa.com/budgeting-and-forecasting) rather than a guess in the last month of the year.

Common questions ## Fort McMurray corporate tax questions **Does an Alberta corporation really file two returns?** Yes. Alberta administers its own corporate income tax, so a corporation with a permanent establishment in the province files the federal T2 with the CRA and the AT1 with Alberta Tax and Revenue Administration. Both are prepared from the same year-end file and filed together. [Ask about your case →](https://www.everstonecpa.com/quick-question) **What is the corporate tax rate in Fort McMurray?** The Alberta rates apply: 11% combined on active business income eligible for the small business deduction (9% federal plus 2% Alberta) and 23% on general income (15% federal plus Alberta’s 8% general rate), on a $500,000 business limit. **I incorporated in another province and moved here. What changes?** If the corporation now has a permanent establishment in Alberta, it likely has an AT1 obligation, and income may need to be allocated between provinces for any year it operated in both. It is worth checking which years are affected before the provincial authority asks. **Do you have a Fort McMurray office?** No. EverStone works online and serves Fort McMurray corporations entirely remotely. Documents move by secure upload, returns are e-signed, and nothing about the engagement requires an in-person meeting. **My corporation has one main client. Is that a problem?** It is worth reviewing. A corporation providing services that would otherwise look like employment can be assessed as a personal services business, which denies the small business deduction and most ordinary deductions. The factors are the same ones used to test worker classification. **I traded in a truck. Why did my tax go up?** Most likely recapture. The trade-in value counts as proceeds of disposition, and if more CCA was claimed on the class than the truck actually lost in value, the excess comes back into income in the year of the trade. **Do you work with corporations outside Fort McMurray itself?** Yes. Corporations based in Anzac, Fort McKay, Conklin, Janvier, Fort Chipewyan and elsewhere in Wood Buffalo have their T2 and AT1 prepared exactly as Fort McMurray ones do, remotely and at the same fixed fee. ## Related services and local guides The rest of what we do for Fort McMurray businesses, the nearest city page, and the reference pages behind this one.
