- Preparing financial statements.
- Completing the T2 return.

๐ก Example
A small business owner provides:
- Bank statements.
- Expense receipts.
- Revenue records.
You convert this into:
- Income statement.
- Balance sheet.
- Tax return.
๐ Key Insight

๐ข 3. Federal vs Provincial Corporate Tax Filing
Many beginners think corporations file separate provincial returns.
๐ Reality

| Alberta | Separate return |
| Quebec | Separate return |
๐ก Example
If a corporation operates in Ontario:
- File one T2 return.

๐ง Key Concept
One return usually covers everything.
๐ข 4. NAICS Code โ Why It Matters
Every corporation must select an industry code (NAICS).
๐ What It Does
- Identifies business activity.
- Helps CRA compare similar businesses.
- Reduces audit risk when accurate.
๐ก Example
A drywall contractor vs bakery:
- Different cost structures.
- Different profit margins.
Wrong classification โ incorrect comparison โ CRA attention.
๐ Tip
Always choose the code that reflects the main revenue activity.

๐ 7. Corporate Tax Instalments
Corporations often pay tax throughout the year.
๐ When Required
If prior-year tax > $3,000
๐ How It Works
Monthly instalments paid to CRA.
๐ก Example
Previous tax = $24,000
Monthly instalment = $24,000 รท 12 = $2,000
๐ Result
- Paid gradually during the year.
- Credited when filing T2.
