How to Contact the CRA for Payroll Support

A practical guide to reaching the CRA Business Enquiries line — phone numbers, hours, what to have ready, and how to skip the wait.

Hours of service

  • Monday to Friday: 8:00 a.m. – 8:00 p.m. local time
  • Saturday: 9:00 a.m. – 5:00 p.m. local time
  • Closed Sunday and statutory holidays

How to skip the long wait time

CRA wait times routinely exceed an hour during peak periods. These small adjustments usually get you through faster:

  • Call Tuesday–Thursday at 8:00 a.m. local time. Mondays and the days around the 15th of each month are the busiest.
  • Avoid the last week of the month. Remittance deadlines flood the line.
  • Use the automated self-service line at 1-800-267-6999 for balances, remittance confirmations, and ordering forms.
  • Sign in to My Business Account — most payroll questions (statement of account, PD7A history, filing T4s, ROE Web) don't require a phone call at all.
  • Request a callback when the automated system offers one instead of waiting on hold.

What to have ready before you call

CRA agents will not discuss the account until they verify your identity. Have these on hand to avoid being asked to call back:

  • Your 15-character payroll program account (e.g. 123456789RP0001)
  • Business number (BN) and exact legal business name
  • Your most recent PD7A statement or remittance voucher
  • Owner's full name, date of birth, and address on file
  • If you're a bookkeeper or accountant: a valid RC59 authorization on file
  • A specific question or reference number — open-ended calls get bounced

Common payroll reasons to call the CRA

  • Register or close a payroll (RP) account
  • Reconcile a PD7A that doesn't match your remittance
  • Resolve a CPP, EI, or income tax discrepancy on a T4
  • Request relief from penalties or interest on late remittances
  • Change remittance frequency (regular, quarterly, accelerated)
  • Confirm a T4 / T4 Summary was received
  • Set up a payment arrangement for arrears

CRA mailing addresses for payroll correspondence

Most payroll correspondence should be sent to the tax centre that serves your province. Always confirm the current address printed on your PD7A or on canada.ca before mailing, and keep proof of delivery for anything time-sensitive.

PurposeWhere to send it
Paper T4 / T4 Summary returnsT4 Program, Jonquière Tax Centre, PO Box 1300 LCD Jonquière, Jonquière QC G7S 0L5
Payroll (RP) account correspondence — Ontario, Quebec, Atlantic, NunavutSudbury Tax Centre, 1050 Notre Dame Avenue, Sudbury ON P3A 5C1

Remittance payments by chequeMail with your PD7A remittance voucher to the address printed on the voucher — do not send payments to a tax centre without one.

Employers with more than 5 information slips must file T4s electronically; paper filing above that threshold can trigger a penalty.

Alternatives to calling

  • My Business Account — view PD7A, file T4s, send secure messages to the CRA (usually answered in 10 business days).
  • Represent a Client — for bookkeepers and CPAs acting on the employer's behalf.
  • ROE Web via Service Canada for Records of Employment.
  • Canadian Payroll handles CRA remittances, T4 filing, and ROEs automatically so most calls become unnecessary. See features.

Tired of calling the CRA?

Canadian Payroll calculates source deductions, remits to the CRA on schedule, and files your T4s — so the only time you'll call is to say hi.
