Frequently asked questions

Will the CRA accept tax documents mailed through PostPal?

Yes. The CRA accepts paper documents delivered via Canada Post regardless of who put them in the mail. PostPal mails through Canada Post, so a letter mailed by us is delivered the same way as one you mailed yourself.

What address should I send to?

Use the address printed on the form or letter you are responding to. Each CRA form has its own designated tax centre — sending to the wrong address will delay processing.

Can I send a return with multiple slips and receipts?

Yes. Standard letters include up to 6 pages, and the extended-page option supports up to 100 pages with a small extra-stamp fee. Most personal returns fit comfortably.

Should I send tax documents by registered mail?

PostPal mails letters as standard Canada Post lettermail. If you want signature-on-delivery or registered mail for proof of receipt, that is a different Canada Post product — let us know before paying and we will recommend a route.

Will my tax information stay private?

Yes. Files are reviewed only for legality, never read or stored beyond the mailing window. They are deleted from our systems after we mail your letter. Payment is handled by Stripe.
