Important Bookkeeping & Tax Dates for BC Small Businesses

  Your GST filing frequency depends on your business (monthly, quarterly, or annually).

• Monthly filers: GST due one month after the reporting period
• Quarterly filers: GST due one month after quarter-end
• Annual filers: See annual section below

Clean, up-to-date bookkeeping makes these much easier to file accurately.

Most small businesses remit:

• CPP
• EI
• Income tax withheld

Due: Usually on or before the 15th of the following month

(Some employers remit more frequently depending on size and history.)

PST Remittances (BC Businesses)

PST filing frequency depends on your registration:

• Monthly
• Quarterly
• Semi-annually
• Annually

Due: Typically by the end of the month following the reporting period

End of February

• T4 slips & T4 Summary due (employees)
• T4A slips & T4A Summary due (contractors, where applicable)

These are some of the most commonly missed deadlines.

April 30

• Personal income tax deadline (sole proprietors with no balance owing)
• Balance owing due for most individuals

Sole proprietors still report business income personally.

June 15: Personal tax filing deadline for sole proprietors

Note: Any balance owing is still due April 30, even though the return can be filed later. 

Corporate Income Tax (T2)

• Filing deadline:
  • 6 months after your fiscal year-end
• Payment deadline:
  • Usually 2–3 months after fiscal year-end (varies)

Clean year-end bookkeeping is critical before this step. 

December / Year-End Preparation

• Reconcile bank and credit card accounts
• Review GST and PST accounts
• Confirm contractor payments (T4A review)
• Prepare clean records for your accountant

Doing this before year-end can reduce accounting fees and stress.

• T4A slips for contractors
• GST payments for annual filers
• PST filings (separate from GST)
• Payroll remittances during busy periods

Most issues aren’t caused by mistakes — just by bookkeeping falling behind. Prepare clean records for your accountant. Doing this before year-end can reduce accounting fees and stress.

Accurate, up-to-date bookkeeping helps:

• Avoid late filings and penalties
• Reduce stress around tax season
• Catch issues early
• Keep year-end costs down

Many BC businesses discover missed deadlines during bookkeeping cleanup — which is fixable, especially when caught early.
