Tax compliance fails quietly: a deadline sits in someone’s inbox, a withholding return gets skipped during a busy month, or a notice arrives that nobody owns. The fix is rarely more software — it is a calendar that is shared, assigned, and reviewed.

Start by listing every obligation that applies to your entity: corporate returns, individual filings where relevant, withholding, and indirect tax (VAT, GST, or sales tax). Add authority-specific nuance for provinces or jurisdictions where you operate.

Assign a named owner for each filing, a preparation lead time (not just a due date), and a checkpoint one week earlier. That buffer is where most recoverable errors show up.

Finally, connect the calendar to your bookkeeping close. Returns filed from incomplete books create amendments later. When monthly reconciliations and tax cut-offs talk to each other, filing becomes a confirmation step — not a scramble.

Stonehenge Solutions helps businesses design these calendars as part of tax compliance engagements, so deadlines and planning sit with the same accountable partner.
