Fixed dates, every year
These do not move, no matter when your corporate year-end is.
- T4 and T4A slips to employees, contractors, and CRA Last day of February
- T5 slips for dividends the corporation paid you Last day of February
- RRSP contribution deadline for the prior tax year 60 days into the year
- Personal tax return (T1) and any balance owing April 30
- T1 filing if you or your spouse have self-employment income June 15
- Payroll source deductions, regular remitters 15th of each month
Dates that move with your year-end
These are the ones owners miss, because no wall calendar shows them. Count from your corporation’s fiscal year-end.
- Corporate tax return (T2) filing deadline 6 months after year-end
- Corporate tax balance owing, most small CCPCs 3 months after year-end
- HST return and payment, annual filers 3 months after year-end
- HST returns, quarterly or monthly filers 1 month after each period
- Corporate instalments, if you owe enough to need them Monthly or quarterly
- T5018 contractor slips (construction) 6 months after the period you choose
Two corporations with different year-ends have completely different calendars, which is why generic deadline lists get people penalized. Confirm your dates against your own year-end, filer type, and remitter category, or have your accountant do it.
