London, Ontario Bookkeeping: Clean Books for Clinics, Trades and Student Rentals
London's healthcare, education-adjacent and rental economy has predictable bookkeeping needs that are easy to keep tidy monthly.
Local guide · HST (13%)
London, Ontario supports a large healthcare and education-adjacent economy, a strong trades sector and a substantial student-rental market. Bookkeeping needs are steady rather than exotic — which makes falling behind unnecessary and easy to correct.
Professional corporations, clinics and property owners benefit most from consistent monthly close and clear year-end handoff files.
What local bookkeeping actually involves in London
Clinic revenue and exempt supplies
Health services are often HST-exempt while retail products are taxable. Revenue streams are separated so tax treatment is correct.
Student rental cycles
Rent rolls, deposits and seasonal vacancy are tracked per property so income is not misstated across the school year.
Professional corporation records
Shareholder loans, dividends and management fees are tracked cleanly for your tax preparer.

What London bookkeeping needs to cover
Monthly reconciliation instead of an annual catch-up
Every bank, credit-card, loan and payment-processor account is reconciled each month. A London business that reconciles only at year-end typically needs 8-15 hours of cleanup per missed year, and files sales tax from figures nobody verified.
HST (13%) coded at the transaction, not estimated later
Tax is coded as each transaction is entered so the HST (13%) summary comes straight out of the ledger. Estimating from bank totals is the most common cause of reassessments, and CRA charges compound daily interest at the prescribed rate plus 4% on arrears.
Supporting records kept for six years
CRA requires books and receipts to be kept for six years from the end of the tax year they relate to. Documents are attached to the transaction in the accounting file, so nothing depends on a shoebox or an inbox search.
Payroll remittances on the CRA schedule
Regular remitters must pay by the 15th of the month after the pay period. Late remittances draw a penalty of 3% to 10% depending on how late, so a remittance calendar is set at onboarding.
A year-end file your tax preparer can actually use
Trial balance, reconciled control accounts, fixed-asset continuity, loan schedules and a working-paper index are handed over together, which removes most of the back-and-forth that inflates year-end fees.
