One firm does the work from start to finish, and the fee is agreed in writing after we review [your enquiry](https://www.everstonecpa.com/book-online?service=monthly#enquiry-form). There is no Oshawa office; the work is remote by design. Published fees start at $125 for a personal return and $325 a month for bookkeeping. ## What an Oshawa business actually files Durham businesses file mostly federally. A corporation files a T2 within six months of year-end, with Ontario corporate tax on the same return. The balance owing is due earlier, two or three months after year-end, and that gap is where penalties and interest start: paying at filing rather than the due date means interest on money already set aside. The corporation also files an Ontario Business Registry annual return within six months of year-end, which the CRA never reminds you about. Employers add payroll, WSIB and possibly Employer Health Tax. Sales past $30,000 over four consecutive calendar quarters require HST registration. Our [Ontario tax facts](https://www.everstonecpa.com/ontario-tax-facts) page lists current provincial rates with sources. ## The services, one page each Every service below has its own Oshawa page, written for how Durham owners use it: - [Bookkeeping in Oshawa](https://www.everstonecpa.com/bookkeeping-oshawa): monthly reconciliations and HST filing, from $325 a month. - Corporate tax (T2) in Oshawa: the year-end return, statements and the registry annual return. - [Personal tax in Oshawa](https://www.everstonecpa.com/personal-tax-accountant-oshawa): T1 returns from $125 for a simple file, and self-employed returns with schedules. - Payroll services in Oshawa: source deductions, WSIB, Employer Health Tax and T4s. Most owner-run companies need more than one of these, and they work better together: the books feed the HST return, the HST return feeds the year-end, and the year-end decides what the owner’s personal return looks like. Choosing an accountant Oshawa owners can keep for all of these means one firm handles the books, the HST return and the year-end together. ## Durham’s main industries, and a page for each Oshawa and the towns around it have a recognisable business mix, and each part of it carries its own accounting problems: - Construction contractors: new subdivisions across Whitby, Oshawa and Clarington mean holdbacks, progress billing, T5018 slips and WSIB. - [Manufacturers](https://www.everstonecpa.com/manufacturer-accountant-oshawa): the automotive heritage left a base of machine shops and parts suppliers that live on inventory, job costing and equipment. - Trucking and logistics: the 401 and 407 corridor puts carriers and owner-operators here, with IFTA, IRP and heavy equipment on the books. - Restaurants: tips, cash, food cost and HST on every bill. - Realtors: commission income, HST on commissions and the Ontario personal real estate corporation. ## Incorporating in Durham, and what changes after Many Oshawa owners incorporate once profit builds. That adds returns, a registry filing, a separate bank account and a yearly salary-versus-dividend choice. It also creates the shareholder loan account: personal costs paid on the company card and not repaid within one year after the company’s year-end are generally taxed as your income. We look at whether incorporation makes sense before you do it, not after. The [when to incorporate](https://www.everstonecpa.com/should-i-incorporate) guide sets out the trade-offs, and the [salary vs dividends calculator](https://www.everstonecpa.com/salary-vs-dividends-calculator) shows how the pay decision moves between the two returns. ## What it costs Fees are fixed in writing first; [published pricing](https://www.everstonecpa.com/pricing) shows where each service starts. Personal returns from $125; monthly bookkeeping from $325 a month with HST filing; a typical trades corporation with bookkeeping, payroll and a year-end T2, $500 to $700 a month. A standalone T2 is quoted after we review your enquiry, since the books drive the work. If you only need one decision made, a 45-minute [Advice Call](https://www.everstonecpa.com/advice-call) costs a flat $225 + GST, with no ongoing engagement attached. ## Remote EverStone serves Oshawa remotely: a cloud ledger you hold the login to, a secure upload link and electronic signatures. Returns and the Ontario registry filing are made online, so nothing depends on being in Durham. Enquiries are answered by email, and the same firm that quotes the work is the one who does it and answers the follow-up questions in the months after. If you have never used an accountant at a distance, working with a CPA outside your province covers what changes and what does not.

General information, not advice. ## Remote accounting for Oshawa Accounting for Oshawa and Durham Region businesses is delivered remotely. **There is no Oshawa office and no local team.** Meetings are virtual, documents are signed electronically, and you deal with the CPA directly rather than a front desk. Common questions ## Questions from Oshawa business owners **Is there an EverStone location in Durham Region?** No. EverStone works online, and serves Oshawa, Whitby, Ajax, Pickering and Clarington entirely by video, phone and secure upload. Every filing involved is electronic, so the distance changes how you reach us, not what gets filed. [Ask about your case →](https://www.everstonecpa.com/quick-question) **Can an accountant in BC file my Ontario corporation’s taxes?** Yes. Ontario corporate tax is administered by the CRA and calculated on the same T2 as the federal tax. The Ontario Business Registry annual return is filed online. Nothing requires the preparer to be in Ontario. **How much does an accountant cost for an Oshawa business?** It depends on the work, and you get the fee in writing first. Personal returns start at $125 and monthly bookkeeping at $325 a month, while a corporate return is quoted after we review your enquiry. See [pricing](https://www.everstonecpa.com/pricing). **I missed the Ontario annual return. Is that a problem?** It can. The annual return is due within six months of year-end, and falling behind risks the corporation’s good standing. Catching up is usually simple. **Can you take over from my current accountant mid-year?** Yes. We ask for last year’s returns and working papers, confirm what has been filed, and pick up from there. [Switching accountants](https://www.everstonecpa.com/switching-accountants) explains the steps. **Do I need to register for HST?** Once your taxable sales pass $30,000 over four consecutive calendar quarters, registration is mandatory, and you charge 13% HST from then on. Many businesses register earlier so they can recover the HST they pay on costs. **Do you work with businesses outside Oshawa itself?** Yes. EverStone works remotely, so businesses in Whitby, Ajax, Pickering, Clarington and the rest of Durham Region are served exactly as Oshawa ones are: video, phone, email and a secure upload link, at the same fixed fees. ## Related services and local guides Nearby cities, the rest of what we do for Oshawa businesses, and the reference pages behind this one.
