Introduction to Debits
In accounting, the term debit is one of the most important concepts in the double-entry bookkeeping system. It works hand in hand with credits to keep financial records accurate and balanced. Therefore, understanding debits is essential for students, business owners, and anyone studying accounting in Canada.
What Is a Debit in Accounting?
A debit is an entry made on the left side of a T-account. Depending on the type of account, a debit can either increase or decrease the balance.
In simple terms:
- Debits increase: Assets, Expenses, and Dividends.
- Debits decrease: Liabilities, Equity, and Revenue.
As a result, this system ensures that the accounting equation Assets = Liabilities + Equity always remains in balance.

How Debits Work in Practice
Example 1: Recording Cash Received
When your business receives $1,000 cash from a customer:
- Debit Cash (Asset) โ increases assets.
- Credit Revenue โ increases income.
Example 2: Paying Rent
Suppose a company pays $2,000 for office rent:
- Debit Rent Expense โ increases expenses.
- Credit Cash โ decreases assets.
Example 3: Purchasing Equipment on Credit
If you buy equipment for $5,000 on account:
- Debit Equipment (Asset) โ increases assets.
- Credit Accounts Payable (Liability) โ increases liabilities.
Debits and the DEALER Rule
Accountants often use the acronym DEALER to remember debit and credit rules:
- D โ Dividends (Debit)
- E โ Expenses (Debit)
- A โ Assets (Debit)
- L โ Liabilities (Credit)
- E โ Equity (Credit)
- R โ Revenue (Credit)
Consequently, debits increase the first three categories (D, E, A) and decrease the last three (L, E, R).
Debits in Canadian Accounting Standards (ASPE vs. IFRS)
Under ASPE (Accounting Standards for Private Enterprises) and IFRS (International Financial Reporting Standards), the use of debits and credits follows the same double-entry principle. Canadian companiesโwhether private or publicโrecord debits consistently in line with these standards. In addition, IFRS requires more detailed disclosures, but the mechanics of debits remain universal.
Debits, Accounts, and CRA Reporting
When Canadian corporations file a T2 corporate tax return, they use GIFI codes to classify accounts. Whether reporting a debit to an expense account or an asset account, these codes make financial reporting consistent across businesses.

Key Takeaway
A debit in accounting is more than just an entry on the left side of a ledger. It increases assets, expenses, and dividends while decreasing liabilities, equity, and revenue. Therefore, mastering how debits work ensures accurate bookkeeping, compliance with Canadian accounting standards, and proper reporting when filing with the CRA.
