Bookkeeping Basics for Self-Employed Professionals

Introduction
Understanding bookkeeping basics for self-employed professionals is essential for anyone running a sole proprietorship, freelance business, independent practice or home-based operation in Canada. Good bookkeeping ensures accurate income reporting, maximizes tax deductions, simplifies GST/QST compliance and reduces the risk of CRA or Revenu Québec audits. Many self-employed individuals start their business with passion and expertise but struggle with recordkeeping, missing receipts, disorganized expenses or incomplete invoices. Poor bookkeeping often leads to higher taxes, penalties, interest and unnecessary stress during tax season. This guide provides the complete bookkeeping basics for self-employed professionals so entrepreneurs can build strong financial foundations and focus on growing their business with confidence.

Legal and Regulatory Framework
Bookkeeping basics for self-employed professionals are governed by the Income Tax Act, the Excise Tax Act, Québec’s Taxation Act and CRA’s detailed recordkeeping requirements. The law requires self-employed individuals to:

• keep complete books and records for six years
• retain all receipts, invoices, contracts and bank statements
• separate personal and business expenses clearly
• report income using the T2125 (Statement of Business or Professional Activities)
• register for GST/HST once income exceeds $30,000
• register for QST when operating in Québec and meeting provincial thresholds
• track mileage and home-office expenses when claiming deductions

Failure to maintain accurate records can result in denied deductions, estimated assessments and penalties. Understanding bookkeeping basics for self-employed professionals ensures compliance with both federal and Québec rules.

Key Court Decisions
Court rulings have repeatedly emphasized the importance of bookkeeping basics for self-employed professionals. Judges have upheld CRA reassessments where taxpayers failed to keep receipts or relied on estimates instead of proper documentation. Courts ruled that self-employed taxpayers must prove expenses with acceptable records such as invoices, receipts or contractual agreements.

Cases involving vehicle expenses confirmed that mileage logs must be detailed and contemporaneous, not reconstructed months later. Courts also disallowed home-office claims where business use was not exclusive or clearly documented. Québec courts highlighted similar issues where businesses failed to keep supporting documents for QST input credits. These rulings reinforce the need for proper bookkeeping basics for self-employed professionals.

Why CRA Targets This Issue
The CRA closely monitors self-employed individuals because they represent a high-risk group for:

• unreported income
• overstated business expenses
• inadequate documentation for deductions
• vehicle expenses with no mileage log
• cash-based transactions
• inconsistent GST/HST filings
• home-office claims with vague calculations

CRA and Revenu Québec use data matching to compare T4A slips, bank deposits, PayPal/Stripe transactions and GST/QST filings. Any inconsistencies may trigger a review. Strong bookkeeping basics for self-employed professionals significantly reduce audit risks.

Real Client Experience
Many self-employed individuals come to Mackisen after years of bookkeeping challenges. One client kept only bank statements without receipts. CRA denied several deductions during a review. Mackisen reconstructed missing documentation, corrected entries and improved future compliance.

Another Québec freelancer claimed QST input credits without proper invoices and faced a provincial reassessment. We organized expenses, submitted additional documentation and negotiated reductions.

A contractor mixed personal and business expenses, creating confusion during tax filing. Mackisen helped separate accounts and created a structured bookkeeping system. A consultant underreported PayPal deposits because they did not track them consistently. We reconciled all online payments and corrected the return. These stories show how proper bookkeeping basics for self-employed professionals improve tax accuracy and financial stability.

Common Questions
Self-employed individuals often ask if they must use bookkeeping software. It is not required, but highly recommended for accuracy. Others ask whether personal bank accounts may be used. It is allowed, but creates confusion and increases audit risk—separate accounts are best.

Many ask how long receipts must be kept. CRA requires six years. Québec mirrors this rule. Others ask how to track mileage. A logbook with date, destination, purpose and kilometers is required.

Questions also arise about GST/HST and QST registration. Registration is mandatory when revenue surpasses the small supplier threshold. Understanding these questions helps clarify bookkeeping basics for self-employed professionals.
