London's insurance head offices, health research cluster and manufacturing base generate professional-corporation files, SR&ED claims and student-rental portfolios around its campuses. Physicians and consultants use Ontario's 3.2% small business rate; landlords manage expense allocation and HST-exempt residential rents; and employers past $1,000,000 of Ontario payroll remit the Employer Health Tax on the excess.
There is no generic Canadian tax return — there is a Ontario return filed from London, with everything that implies. Here is what it implies, from an accountant who deals with it daily.
The very first line item we confirm for any London client: Ontario uses a single 13% HST administered by the CRA, so you file one combined return rather than separate federal and provincial ones. Everything downstream — invoicing, bookkeeping, the year-end file — inherits that setup.
Owners often plan their year-end around the federal picture and only then remember the province. Ontario applies a 3.2% small business rate on the first $500,000 of active business income, giving a 12.2% combined federal-provincial rate. For a London corporation, that provincial piece belongs in the plan from the start, not as a footnote.
The payroll question we field most from growing London companies is not about deductions — it is about the provincial levy. Employer Health Tax (EHT) applies above a $1,000,000 annual payroll exemption for eligible employers. Where your headcount and payroll are heading decides how soon this matters to you.
Provincial credits are the most commonly unclaimed money we see: Ontario Innovation Tax Credit, Ontario Made Manufacturing Investment Tax Credit, Ontario Regional Opportunities Investment Tax Credit are all worth a look in an eligible year. London clients feel this one directly on the first return we file together.
The work that crosses a tax consultant's desk in London mirrors the local economy — finance, professional services, manufacturing, technology and healthcare — so the recurring questions are the ones those sectors generate: how income is earned, what gets deducted, and where the provincial rules bite.
We serve London at the same fixed fee as everywhere else in Canada, with no location premium, and you pay only after your filing is done.

22 months of records at a marketing agency in London, Ontario had never been reconciled. That left a provincial payroll levy that had never been registered for or remitted. Rebuilding recovered $7,300.
Nothing reconciled at a marketing agency in London, Ontario. Every filing started with 22 months of cleanup. The file was carrying a provincial payroll levy that had never been registered for or remitted. We rebuilt from source rather than correcting on top of the existing file. We assessed and claimed Ontario Innovation Tax Credit alongside the federal return. Then we set the routine that keeps it clean. 22 months reconciled to the bank. The close now takes 5 days, and $7,300 of previously unclaimable input tax was recovered in the process.
Collections had begun against a private lending business in London, Ontario over 5 years of unfiled returns. Bringing them current cut $80,000 from the balance.
By the time a private lending business in London, Ontario called, 5 years were outstanding. The CRA had assessed on estimates. Underneath it sat 13% HST charged on every sale regardless of where the customer was located. We reconstructed the records year by year. We recalculated the corporate tax at the 12.2% combined small business rate and rebased the instalments on the current year. Each filing replaced an arbitrary assessment with a real one. The account is current. Filing on real numbers rather than CRA estimates reduced the balance by $80,000, and a relief application addressed part of the accumulated interest.
A medical imaging clinic in London, Ontario expanded into a second province. The file already carried sector-specific exposure the previous accountant had not seen before. Every obligation was set up in advance and $90,000 of cash released.
Revenue at a medical imaging clinic in London, Ontario was up sharply and cash was tighter than ever. Underneath it sat sector-specific exposure the previous accountant had not seen before. We assessed and claimed Ontario Made Manufacturing Investment Tax Credit alongside the federal return. Every new obligation was set up before it was triggered, not after. That covered registration, remittance frequency and provincial filing. $90,000 of cash was released from the working capital cycle. The expansion completed with every registration and filing obligation covered from day one.
A 3-week rebuild at a two-dentist practice in London, Ontario got the filing in with 13 days to spare. That avoided $22,500 in penalties.
A two-dentist practice in London, Ontario was weeks away from the deadline for its ON tax and accounting file. Behind that sat out-of-province sales billed at the ON rate instead of the customer’s. The exposure if the date slipped was around $22,500. We registered the provincial payroll account, caught up the outstanding remittances, and applied for relief on the penalty. The filing went in complete rather than provisional, so there was no amended return to follow. Filed with 13 days to spare. $22,500 in late-filing penalties avoided, and the working papers are ready for the following year.
A family transfer at an IT managed-services provider in London, Ontario would have been fully taxable. The reason was a minute book with no resolutions behind a decade of dividends. Restructuring deferred $345,000.
A generational transfer at an IT managed-services provider in London, Ontario had been discussed for years without a plan. A minute book with no resolutions behind a decade of dividends meant the transfer as contemplated would have been fully taxable. We rebuilt the sales ledger by customer location, applied the correct place-of-supply rate to each stream, and filed the adjusted HST returns. We sequenced the steps so each one was complete and documented before the next depended on it. $345,000 of tax was deferred through the transfer, and the successor generation took over a corporation whose records stood up to review.
A furniture manufacturer in London, Ontario was filing correctly and still overpaying. The reason was a provincial payroll levy that had never been registered for or remitted. Restructuring the position cut $56,000 from the annual bill.
A furniture manufacturer in London, Ontario was compliant but paying more than it needed to. The prior year had been filed correctly. It still left a provincial payroll levy that had never been registered for or remitted on the table. We modelled the current position against the alternatives before changing anything. Then we assessed and claimed Ontario Innovation Tax Credit alongside the federal return. The change saved $56,000 in the first year and repeats annually. Nothing about the filings became more aggressive. The position is simply the one the rules already allowed.

Yes, and doing both together is where most of the planning value sits. Salary-versus-dividend mix, shareholder loans and RRSP room interact across the two returns, and treating them separately is how owners overpay. Explore all our services.
That is routine work for us. We rebuild the ledger year by year, file the outstanding returns in sequence, and where eligible apply to the CRA's Voluntary Disclosures Program to reduce penalties and interest.

Ontario uses a single 13% HST administered by the CRA, so you file one combined return rather than separate federal and provincial ones. Most London owners meet this rule for the first time at their first year-end with us.
Ontario applies a 3.2% small business rate on the first $500,000 of active business income, giving a 12.2% combined federal-provincial rate. It is usually the first correction we make on a new London file.
The questions Canadians actually search on this topic, answered plainly. Browse every question in the Canadian tax answers directory.
Sales tax in Ontario is 13% HST for 2026, made up of the 5% federal GST and an 8% provincial share, and it has applied at that rate since 1 July 2010. There is no separate Ontario retail sales tax on top, and the CRA administers the whole 13%. Basic groceries and prescription drugs are zero-rated, so they carry nothing. Income tax is a separate calculation with its own federal and Ontario brackets.
Online banking is the simplest route: add the CRA as a payee, select the account and tax year precisely, and pay from your chequing account. CRA My Payment takes debit card payments, and pre-authorised debit can be scheduled in My Account or My Business Account for a single amount or a run of instalments. Corporations and GST/HST registrants use the same channels under their business number. Keep the confirmation number and allow several days for the payment to post.
Ontario families receive the federal Canada Child Benefit plus the Ontario Child Benefit, and the CRA pays both together in one monthly deposit. Both are income tested, so entitlement falls as family adjusted net income rises, and both are recalculated every July from the prior year return. The provincial portion is set by Ontario and the federal portion by Ottawa, so your deposit changes when either programme is adjusted. Both spouses must file returns to keep payments running.
Three different calculations go by that name. For sales tax, multiply the price by the harmonised rate that applies to the province of supply. For income tax, apply the federal brackets and then the Ontario brackets to taxable income and subtract your credits. For payroll, the CRA payroll deductions calculator handles income tax withholding along with CPP and EI for each pay period. Look up the rates and brackets published for the year you are calculating, since they change annually.
Ontario does not issue its own refund; the Canada Revenue Agency assesses your T1 and pays the combined federal and Ontario amount. A return filed online is usually processed in about two weeks, and a non-resident return can take up to 16 weeks. Filing for the 2025 tax year opened 23 February 2026. Register for direct deposit and watch My Account for the assessment, and note that amounts you owe the CRA or certain other agencies can be applied against a refund.
Yes. Tips and gratuities are taxable income in Ontario, whether they arrive through payroll, a card terminal, a tip pool or straight cash. Where your employer controls and distributes them, they are normally run through payroll with income tax, CPP and EI withheld. Tips paid to you directly are yours to report on your own return. Keep a running daily record, because unreported tips are a common focus of CRA review in hospitality.
The CRA opens online filing in late February and begins processing returns then. For the 2025 tax year, online filing opened on 23 February 2026 and closes on 29 January 2027. Filing early does not usually get you a refund sooner than the two-week online processing window, but it does confirm benefit and credit payments that depend on your assessed return. Slips from employers and payers are generally available by then.
Yes, and you should file straight away. Returns can be filed long after the due date, and online filing for the 2025 tax year stays open until 29 January 2027. If you owe, a late-filing penalty is charged as a percentage of the balance plus a monthly amount, and interest runs from the payment due date, which was 30 April 2026 for 2025. If you are owed a refund or benefits, nothing is lost by filing late.
Yes, in more than one way. Municipalities charge annual property tax on land and any buildings on it, based on assessed value. Selling land can trigger tax on the gain, with one-half of a capital gain included in income for 2025 and 2026, or full business income if you were effectively trading in land. GST/HST often applies when a business sells vacant land, while a sale of personal-use land by an individual is frequently exempt. Provincial land transfer tax normally falls on the buyer.
Multiply the hourly rate by your weekly hours, then by the paid weeks in the year: 52 where vacation is paid, fewer where it is not. Going the other way, divide the annual salary by 52 and then by weekly hours. Either way the answer is gross pay, before income tax, CPP and EI come off, so your deposits will be smaller. Overtime, bonuses, statutory holiday pay and unpaid leave all shift the real annual total.
Taxable profit is accounting profit adjusted to the rules in the tax law. Start from net income in the financial statements, add back amounts that are not deductible, such as accounting depreciation, reserves and the non-deductible portion of meals and entertainment, then deduct tax-specific claims such as capital cost allowance and losses carried forward. The result is the figure the rates apply to: for 2026, 9% federally on the first $500,000 of active business income for a small corporation.
For account-specific questions, the CRA will discuss your own file once you have verified your identity, and its individual and business enquiry lines cover balances, slips and deadlines. For advice on what to claim or how to structure something, speak to a tax preparer. If you want the filing handled for you, taxfilings.ca agrees a fixed fee before any work starts, and you pay after the service. Call +1 (416) 619-0068.
