Accountant and CPA for Windsor and Essex County businesses

Windsor faces Detroit, and much local income comes from across the river. EverStone CPA, accountants in Windsor, Ontario, serves Windsor, LaSalle, Tecumseh, Lakeshore, Leamington and Essex County remotely: corporate tax, bookkeeping, payroll and advice at a fee fixed in writing first.

Who this page is for: owners of tool, die and mould shops, cross-border trucking companies, Leamington and Kingsville greenhouses, construction contractors and retailers who want one firm to hold the whole file.

Nearby, EverStone also serves London and the Kitchener-Waterloo area.

Quick answer: A Windsor business files the same federal returns as any Ontario business, but it often bills in US dollars, ships goods south that are zero-rated for HST, and runs payroll through seasonal peaks. EverStone handles the T2, 13% HST, payroll, bookkeeping and the owner’s T1 for Windsor and Essex County owners, entirely online, with the fee agreed before work begins. Published fees start at $125 for a personal return and $325 a month for bookkeeping.

For a one-owner Windsor corporation, our accounting fees for monthly bookkeeping, payroll and the year-end T2 with statements usually run from $500 to $700 a month all-in.

A border city keeps two currencies in its books

Few Canadian cities trade so closely with the US. A Windsor mould shop quotes Michigan in US dollars, carriers are paid in US dollars for Detroit runs, greenhouses sell through US distributors. The ledger is in Canadian dollars, so every US item is translated, and the gap between invoice-date and receipt-date rates is income or loss.

It needs deliberate setup: a US-dollar bank account in the books, one rate source and month-end revaluation. See foreign exchange gains and losses. Goods exported to US customers are generally zero-rated: no HST charged, credits still claimed. HST on exports covers the proof.

What Ontario adds to a Windsor file

Ontario sales tax is simple: one 13% HST registration and return. Corporate tax rides on the T2. Employer Health Tax applies above the exemption, and most construction and manufacturing employers carry WSIB.

Ontario corporations also file an Ontario Business Registry annual return within six months of year-end, outside the CRA calendar and easily missed. See Ontario tax facts and the Ontario accounting guide.

The industries that shape the work here

Essex County’s economy leans on a handful of sectors, and each one brings its own accounting pattern. We have written a page for each:

  • Manufacturers: tool, die and mould makers and automotive suppliers, with job costing, work in progress, heavy equipment and SR&ED claims on process work.
  • Trucking and logistics: cross-border carriers and owner-operators, with IFTA and IRP, US-dollar revenue and long-haul meal claims.
  • Greenhouse growers: Leamington and Kingsville operations taxed as farms, with energy costs, zero-rated produce and seasonal workers.
  • Construction contractors: T5018 slips, the 10% holdback under the Construction Act, progress billing and WSIB.
  • Retailers: inventory counts, shrinkage, point-of-sale reconciliation and HST.

Services Windsor owners use most

Most engagements combine several of these under one fixed monthly or annual fee:

  • Bookkeeping in Windsor: monthly reconciliation, US-dollar accounts kept straight, and the HST return filed from the same ledger.
  • Corporate tax in Windsor: the T2 and year-end statements, with CCA on equipment and planning before the year closes.
  • Personal tax in Windsor: T1 returns for owners, families and residents who earn income in Michigan.
  • Payroll in Windsor: source deductions, EHT, WSIB reporting and T4 slips.

Where the decisions have outgrown a monthly close, fractional controller or fractional CFO support adds cash-flow forecasting and margin reporting.

How a Windsor owner’s year runs

Your year-end, not December, sets the calendar. Books close monthly, and before year-end we raise open decisions: equipment timing, salary-dividend mix, retaining profit. The T2 is due six months after year-end, but the balance owing two or three months after, which catches owners out. The Ontario return has its own six-month clock, and T4, T4A and T5 slips go out by the last day of February. Deadline reminders can email you the dates.

What it costs

Fees are fixed in writing after review, so a June question does not start a meter. Bookkeeping starts at $325 a month with HST included; personal returns from $125; self-employed T1s commonly $275 to $500. Corporate tax alone is quoted after review. A 45-minute Advice Call is a flat $225 + GST. See the pricing page.

Common questions

Questions from Windsor business owners

Can an accountant in BC handle a Windsor corporation?+
Yes. T2, HST and payroll are federal, Ontario tax rides on the T2, and Employer Health Tax, WSIB and the Registry are online. Ask about your case →
Do I charge HST on parts shipped to Michigan?+
Goods exported to a customer outside Canada are generally zero-rated, so no HST is charged, and you still claim input tax credits on the costs of making them. Keep the shipping and customs records that show the goods left the country.
How do you handle invoices in US dollars?+
Each US-dollar invoice is recorded at a consistent exchange rate, the payment at the rate on the day it arrives, and the difference is booked as a foreign exchange gain or loss. US-dollar bank accounts are reconciled in both currencies each month.
Do you work with businesses outside the city itself?+
Yes. LaSalle, Tecumseh, Amherstburg, Lakeshore, Kingsville, Leamington and the rest of Essex County are served the same way, by video, phone and secure upload link.
What does the first meeting cost?+
Nothing. Your enquiry is free, and you get a written fixed quote and no obligation to accept it.
Do you work with businesses outside Windsor itself?+
Yes. EverStone works remotely, so businesses in LaSalle, Tecumseh, Lakeshore, Leamington and the rest of Essex County are served exactly as Windsor ones are: video, phone, email and a secure upload link, at the same fixed fees.
