Tax Services in Mississauga Under One Roof
Most tax problems cross categories: a business owner has a personal return, a corporate return, and a sales tax account, and errors happen in the gaps between separate providers. Our tax services in Mississauga close those gaps by running every filing from one file:
Personal tax (T1)
for employees, self-employed individuals, landlords, and investors
Corporate tax (T2)
with year-end statements prepared from the same numbers
GST/HST registration and returns,
mapped to the provinces you actually sell into
Payroll accounts and T4 filings,
so employee reporting never slips a February deadline
CRA reviews, audits, and objections,
handled by us as your authorized representative
Cross-border and non-resident filings,
for income that does not stop at the border
Tax Preparation Services in Mississauga: The Annual Cycle
Our tax preparation services in Mississauga run on the CRA's calendar, not on filing-season panic. Here is the cycle every client file follows:
January to February: documents in.
You receive one checklist matched to your slips and situation, because chasing papers in April is what makes returns late.
February to April: personal returns out.
T1s are filed as documents complete, with every credit and deduction your file supports claimed and documented.
April 30: payment day for everyone.
Even self-employed filers who file by June 15 must pay by April 30, and interest compounds daily from May 1, so we calculate balances early.
Year-round: corporate deadlines.
T2s are due six months after year-end, with balances due two to three months after, so each corporation's dates sit in our calendar, not in your memory.
After filing: nothing goes quiet.
Notices of assessment are reviewed against what we filed, because CRA adjustments deserve a response, not a shrug.
A Tax Consultant in Mississauga for the Decisions Between Filings
Filing reports the past. A tax consultant in Mississauga earns their keep on the decisions that have not happened yet:
Salary or dividends from your corporation, modelled both ways before you pay yourself
Incorporation timing, tested against your actual profit rather than a rule of thumb
RRSP versus TFSA versus corporate investing, ranked for your bracket and your timeline
Selling a property or a business, planned before the sale, when exemptions can still be used
Instalment planning, so quarterly payments match reality instead of triggering interest
Each consultation ends with the numbers in writing, because advice you cannot show your spouse or partner is advice you cannot act on.
Mississauga Tax Deadlines on One Calendar
| Deadline | Who it applies to | What happens if missed |
|---|---|---|
| April 30 | Most T1 filers, and every balance owing | Late-filing penalty plus daily compounding interest |
| June 15 | Self-employed T1 filing (payment still April 30) | Late-filing penalty on any balance owing |
| 6 months after year-end | Every corporation's T2 | Penalties on tax owing, compounding with repetition |
| 2 to 3 months after year-end | Corporate tax balances | Daily interest from the due date |
| Last day of February | T4 and T4A filings for employers | Per-slip late penalties |
| Mar 15, Jun 15, Sep 15, Dec 15 | Personal instalment payers | Instalment interest on shortfalls |
These dates come from the CRA's own 2026 deadlines calendar, and weekend dates roll to the next business day.
How to Judge the Best Tax Accountant in Mississauga
Searching for the best tax accountant in Mississauga returns a wall of firms all claiming excellence, so here is a checklist that separates them, and we invite you to score Bestax against every line:
- Do they handle personal, corporate, and GST/HST together, or will you manage the gaps?
- Will they represent you if the CRA reviews a return they filed, or does help end at filing?
- Do they review your notice of assessment, or does the file close on submission?
- Is planning offered before year-end, when it can still change the outcome?
- Can they show the deadline calendar they run your file on?
Any firm that clears all five is worth hiring. That is the standard we built this page to meet.
The Tax Accountant Mississauga Businesses Keep Year After Year
Retention is the honest metric in this industry, and the reason clients stay is structural. The tax accountant Mississauga owners keep is the one holding the whole picture:
Our personal income tax and corporate tax teams work from one client file
Salary-dividend mix, corporate year-end, and family credits are planned as one system, not three appointments
Mississauga, Brampton, and Oakville clients meet us in person on Hurontario Street
Everyone else in Canada gets identical service by secure upload and video

- Notices of assessment are checked against filed returns
- Deadlines live in our calendar and reach you in advance
- Planning conversations happen before year-end, not after
