Good Monday provides corporate tax preparation, tax planning, and CRA compliance support for small businesses across Toronto and the GTA. We handle everything from T2 corporate returns and GST/HST filings to year-round tax planning designed to legally minimize what you owe — so tax season is never a surprise.

Tax planning happens throughout the year, not in the last week of March. We build a plan tailored to your business structure, income timing, and growth stage to legally reduce your tax liability and avoid surprises.
We compile accurate Notice to Reader (NTR) financial statements that satisfy CRA requirements and give lenders, partners, or investors a clear picture of your business.
If your business needs to make quarterly tax instalments, we calculate the right amounts and track due dates so you avoid CRA interest and penalties for underpayment.
We handle GST/HST return preparation and filing on your required schedule (monthly, quarterly, or annual), and help you register correctly if you’re approaching the revenue threshold.
Payroll deductions, CPP, EI, and source deduction remittances are prepared and submitted accurately and on time, keeping you compliant with CRA payroll requirements.
If the CRA opens a review or audit of your business, we organize your records, respond to CRA correspondence, and liaise directly with auditors on your behalf so you’re not navigating it alone.

Accounting software helps you record transactions, but it doesn’t replace professional tax review. Software won’t catch missed deductions, flag compliance issues, or plan your tax strategy — an accountant does.
A bookkeeper records day-to-day transactions and keeps your books organized. A tax accountant uses those books to prepare accurate filings, ensure CRA compliance, and plan strategies to reduce what you owe. Good Monday provides both, so nothing gets lost in the handoff.
Cost depends on your business’s size, transaction volume, and complexity. Good Monday’s packages start from $250/month and include tax filing, GST/HST, and payroll compliance — see full packages →.
