Implement Departmental Accounting

Medium-sized business accounting must track revenue and expenses by department, location, or cost centre — not just at the company level. Departmental accounting reveals which divisions are profitable and which drain cash. Without this breakdown, your medium-sized business makes resource decisions blind and overspends on underperforming operations for years.

Reconcile All Accounts Monthly

Every bank account, credit card, loan, and intercompany balance in your medium-sized business accounting must be reconciled monthly. Unreconciled accounts create compounding errors that distort financial statements and cause incorrect T2 corporate tax filings. CRA flags revenue mismatches between your accounting records and filed returns during desk reviews.

Automate Payroll Compliance

Medium-sized businesses with growing teams face higher payroll complexity. Your accounting system must automate CPP, EI, and income tax calculations and flag remittance deadlines. CRA charges 10% penalties on repeat late payroll remittances plus daily compound interest. Integrated accounting with automated payroll prevents these costly errors across every pay period.

Track HST Input Tax Credits Consistently

Your medium-sized business accounting must capture GST/HST paid on every eligible purchase as transactions occur. Businesses that batch-enter expenses quarterly miss thousands in recoverable input tax credits on HST returns filed via NETFILE. Consistent accounting of ITCs directly reduces your net HST remittance and improves cash flow every filing period.

Prepare Monthly Financial Statements

Medium-sized business accounting should produce monthly income statements, balance sheets, and cash flow reports — not just at year-end. Monthly financial statements let your CPA identify mid-year tax planning opportunities like bonus declarations, asset purchases for CCA on Schedule 8, and salary-dividend optimization before your fiscal year closes.

Budget for Corporate Tax Instalments

Your medium-sized business accounting must forecast quarterly corporate tax instalments and include them in cash flow projections. CRA charges compound interest at prescribed rates on late or insufficient instalments. Proper accounting that models the prior-year, second prior-year, and current-year methods ensures you choose the lowest payment option every quarter.

Consolidate Multi-Entity Accounting

Medium-sized businesses operating through multiple corporations need consolidated accounting that tracks intercompany transactions, eliminates duplicates, and reconciles shared expenses. Associated corporations must allocate the $500,000 SBD limit on Schedule 23 of each T2 return. Inconsistent multi-entity accounting leads to CRA reassessments and interest on misallocated deductions.

Monitor Accounts Receivable Aging Weekly

Medium-sized business accounting must include weekly accounts receivable aging reviews. Invoices past 90 days hurt cash flow and may qualify as bad debt deductions under ITA paragraph 20(1)(p). Proper accounting of uncollectible receivables reduces taxable income on your T2 return and keeps your financial statements accurate for lenders.

Review Vendor Costs Quarterly

Your medium-sized business accounting should include quarterly variance analysis comparing actual vendor costs against budget. As businesses grow, subscriptions, contractor fees, and supply costs creep upward without review. Quarterly accounting analysis catches overspending before it erodes a full year of profit and inflates your corporate tax liability unnecessarily.

Use Accounting Data for Tax Planning

Medium-sized business accounting provides the data your CPA needs for mid-year tax decisions — when to purchase assets, whether to declare bonuses before year-end, and how much to pay as salary versus dividends. Without timely accounting reports, these decisions happen after your fiscal year-end when most corporate tax savings options have already expired.
