A corporate tax return may depend on bookkeeping cleanup, HST reconciliation, payroll records, shareholder loan review, and year-end financial statements. A personal tax return may involve self-employment income, rental property reporting, foreign slips, medical receipts, donations, and CRA follow-up.
