Running a business means juggling operations, clients, growth — and of course, tax compliance. Whether you operate a corporation, partnership, or small business, Canada’s tax system brings annual filing requirements, strict deadlines, and ongoing record-keeping obligations. At Haddad Financials, our goal is to make business tax filing simple, accurate, and stress-free.

Below is an overview of what business tax services include, key deadlines you should know, and the documentation required to ensure your filing is complete and compliant.

What Are Business Tax Services?

Business tax services involve preparing, reviewing, and filing the required tax forms for your company, including:

T2 Corporate Income Tax Return
GIFI Financial Statements (Balance Sheet & Income Statement)
Schedule 50 (Shareholders)
Schedule 1 (Net Income for Tax Purposes)
GST/HST Returns
Payroll remittances & T4/T5 filings
Partnership filings (T5013)
Capital Cost Allowance (CCA) schedules
Corporate minimum tax, refundable taxes, and small business deduction calculations

Good tax preparation ensures you:

✔ meet CRA deadlines

✔ maximize allowable deductions

✔ remain compliant

✔ avoid interest, penalties, or reassessments

Key Filing Deadlines for Businesses

Can I Provide My Own Bookkeeping Instead of Having You Do It?

Yes. Haddad Financials offers full bookkeeping and accounting services; however, clients may choose to provide their own bookkeeping summaries (Excel, QuickBooks export, income/expense summary).

If your records are complete and organized, we offer a discounted tax preparation fee for using your self-prepared bookkeeping.
