Personal tax (T1) · London, Ontario

Personal tax accountant in London, Ontario

Around London, a personal return is rarely just a T4. It carries dividends from a family company, a trade run on the side, farm income from a few hundred acres outside Strathroy, or rent from a unit near campus. EverStone prepares T1 returns for London owners and families remotely, from $100 for a simple return and at a fee fixed in writing.

Quick answer: Most London, Ontario residents file by April 30. If you or your spouse are self-employed the deadline is June 15, but any balance is still due April 30. EverStone prepares personal returns from $100 each, and self-employed returns with schedules commonly cost $250–$450 with the fee confirmed before work begins.

When your income comes from your own company

For an incorporated owner, the T1 is the second half of a decision made on the corporate side. Salary shows up on a T4, dividends on a T5, and the mix between them decides how much tax is paid overall and how much RRSP and CPP room you build. Preparing the personal and corporate returns together means the choice is made once, with both returns in view, rather than discovered in April. Family members who work in the business, and any shareholder loan balance, are part of the same conversation.

Ontario tax sits on top of the federal return

The Ontario calculation is part of the T1 and filed with it; there is no separate provincial return. It is not a simple percentage, though. Ontario adds a surtax calculated on the provincial tax itself, and the Ontario Health Premium is a separate line that rises with income. Both affect owners who take a large dividend in a good year more than people on a steady salary, which is one reason to plan the year’s draws rather than take them as cash is needed. A large one-off dividend to pay for a truck or a renovation can cost noticeably more than the same amount spread over two years, and that is something to see in December, not in April.

Self-employed: later to file, not later to pay

A sole proprietor — a framer, an owner-operator leased to a carrier, a hairstylist renting a chair downtown — reports business income on form T2125 and has until June 15 to file. The balance is still due April 30, and interest runs from then. Once net tax owing passes $3,000 in the current year and in either of the two years before, the CRA expects quarterly instalments on March 15, June 15, September 15 and December 15. Keeping a vehicle log and receipts through the year makes the return faster and easier to defend. See the self-employed tax return page for what goes on the schedules.

Farm families and the capital gains exemption

Farm income is reported on its own statement and can use the cash method. Two personal-tax rules matter more to Middlesex County farm families than any deduction: qualified farm property can be eligible for the lifetime capital gains exemption, and farmland can pass to a child under the intergenerational rollover. Both depend on how the land has been owned and used over years, so they are planned well before a sale or transfer. Where farming is not the family’s chief source of income, the restricted farm loss rules can limit how much of a loss offsets other income. See farm accounting around London.

Landlords near campus and across the city

London has a large rental market around the university and the colleges, and many owners hold a unit or two alongside their business. Rental income goes on its own schedule, repairs are separated from improvements, and capital cost allowance on the building is optional and cannot create a rental loss. Whatever is claimed can come back as recapture when the property sells, alongside the capital gain. See rental income tax returns.

Students and new graduates

With Western and Fanshawe in the city, a good share of London returns belong to students, and to parents asking what to do with a student’s slips. Tuition slips come from the school. The credit is used first against the student’s own tax. What is left can be transferred to a parent or grandparent within the annual limit, or carried forward indefinitely to a year when the student earns enough to use it. Filing every year, even on low income, keeps that carry-forward on record and can bring in benefit payments a student would otherwise miss.

Common questions

London personal tax FAQ

How much is a personal tax return in London?+
From $100 for a straightforward T1. A self-employed return with business schedules is commonly $250–$450 depending on the schedules. The fee is confirmed in writing before any work starts. Ask about your case →
I drive long-haul as an employee. Can I claim meals?+
Employed long-haul drivers can claim meal and lodging costs on trips that meet the CRA’s conditions, with a form signed by the employer and a logbook to support it. Owner-operators claim through their business instead.
Do I need to pay instalments?+
If your net tax owing is more than $3,000 this year and was more than $3,000 in either of the two previous years, generally yes. The CRA sends reminders, and paying the amounts it suggests avoids instalment interest.
Can you file returns from previous years?+
Yes. Late years are filed oldest first from the slips the CRA holds and your own records. Where penalties apply, we look at whether relief is available before anything is paid.
I disagree with my notice of assessment. What now?+
A notice of objection has to be filed within 90 days of the date on the notice. Often a call or a letter with the missing document resolves it sooner, and we can review the assessment first.
We moved to London from another province. Which province do we file in?+
The province you lived in on December 31. If you arrived in London in the autumn, the whole year is taxed as an Ontario resident, including the months you lived elsewhere, and the return is prepared on that basis.
Can you prepare my parents’ returns too?+
Yes. Pension income splitting between spouses, medical expenses and the transfer of unused credits all work better when the family’s returns are prepared together, and each return still has its own fixed fee.
Do I have to meet in person?+
No. London returns are prepared entirely remotely: slips come directly from the CRA, documents through a secure upload link, and the T183 authorization is signed electronically.
Do you work with businesses outside London itself?+
Yes. Returns for people in St. Thomas, Strathroy, Woodstock and the rest of Middlesex County are prepared the same way as for London: documents come in through a secure upload link, and the fee is the same.
