us_ca_tax_calendar

  • US + Canada federal tax deadlines (annual calendar)

    Annual calendar of US federal (IRS) and Canada federal (CRA) tax deadlines for calendar-year filers: income-tax filing and payment dates, quarterly estimated payments / instalments, corporate, trust and exempt-organization returns, RRSP and IRA/HSA contribution deadlines, FBAR, and employer slip issuance (W-2/1099-NEC, T4/T5). Rule-derived from the published IRS and CRA deadline schedules with the official weekend/holiday next-business-day adjustments applied (including DC Emancipation Day for US Tax Day). Regenerated each run for a rolling window of tax years.
