Frequently Asked Questions

What do Montreal accounting firms do?

Montreal accounting firms help businesses and individuals stay financially organized and navigate Quebec and Canadian tax laws. They handle day-to-day money matters and offer guidance to support better financial decisions. Core services include:

Financial statement preparation
Bookkeeping and record keeping
Tax planning and filing
Payroll processing
Audit services
Budgeting and cash-flow support
Business advisory
Compliance assistance

What information do I need to provide to an accounting firm?

At the beginning of your collaboration with an accounting firm, you will need to provide basic identification documents (legal name, tax ID, and contact details), your previous year's tax filing, and all pertinent financial records.

These financial records must cover all sources of income, including forms like W-2s, 1099s, and investment documentation, as well as proof of all deductible expenditures, i.e., receipts, invoices, and bank statements.

How do Montreal accounting companies calculate their rates?

Montreal accounting companies typically use three core structures when calculating their rates: hourly billing, fixed project fees, and annual retainer packages. The final cost is determined by the scope and complexity of the services, specifically whether the work involves just bookkeeping and basic tax filing or advisory services as well (auditing, tax planning), as well as the firm’s specialization and location.

How can I verify an accounting company's credentials?

You can verify an accounting company's credentials by checking the public register of the Ordre des comptables professionnels agréés du Québec (CPA Order) to confirm that the individual CPAs are members in good standing and authorized to practice public accounting. Additionally, it is recommended to search the Order's records for any disciplinary decisions or limitations on their practice rights.

Can Montreal accounting firms scale services as my business grows?

Montreal accounting firms are typically well-equipped to scale their services as your business grows, transitioning from basic compliance and bookkeeping for smaller operations to more complex assurance, tax planning, and fractional CFO advisory roles as your needs evolve.

The majority of the firms offer modular packages that allow businesses to add services like audit preparation, business valuation, and specialized international tax advice as their needs expand.
