Where to mail a GST/HST return (and who is still allowed to)
Mail your paper GST/HST return to the address printed on your personalized GST34-2 return — for most paper filers that is GST/HST Returns and Rebates Processing, Prince Edward Island Tax Centre, 275 Pope Road, Summerside PE C1N 6A2. But first, an honest warning: for reporting periods that begin in 2024 or later, electronic filing is mandatory for almost all registrants. Paper is only allowed for charities, selected listed financial institutions, and registrants with an approved exemption.

How to mail it, step by step
- 1
Confirm you are actually allowed to paper-file
For reporting periods starting in 2024 or later, e-filing (NETFILE, My Business Account, or EDI) is mandatory for nearly everyone. Only charities, selected listed financial institutions, and registrants the CRA has specifically exempted may still file on paper. If you e-file, stop here — no envelope needed.

Find the address on your personalized GST34-2
The CRA mails eligible paper filers a personalized GST34-2 return with the correct processing address pre-printed on it. That address always wins. If you lost your personalized return, call the CRA business enquiries line (1-800-959-5525) to request a replacement rather than using a blank form.
- 3
Complete the return and attach any payment correctly
Fill in your line 101 sales, your net tax, and sign where required. If you owe money, note that amounts of $10,000 or more must be paid electronically or at a financial institution — do not staple a large cheque to a paper return.

Mail it before your filing deadline
Your deadline depends on your reporting period (monthly, quarterly, or annual). Upload the completed return to PostPal and we print it and deposit it with Canada Post the next business day — $6 flat, no account needed.
Common questions
Can I still mail my GST/HST return?
Only in limited cases. For reporting periods beginning in 2024 or later, electronic filing is mandatory for almost all GST/HST registrants. Paper returns are accepted only from charities, selected listed financial institutions, and registrants who have an approved exemption from the CRA. Everyone else must use NETFILE, My Business Account, or another electronic method.
What address do I mail my paper GST/HST return to?
The address printed on your personalized GST34-2 return — the CRA pre-prints the correct one for your account. The named processing site is GST/HST Returns and Rebates Processing, Prince Edward Island Tax Centre, 275 Pope Road, Summerside PE C1N 6A2, but your personalized return takes precedence if it shows something different.
What happens if I paper-file when I was supposed to e-file?
The CRA can charge a penalty for failing to file electronically when required, even if your return is complete, accurate, and on time. If you are not a charity, a selected listed financial institution, or an approved exemption holder, file electronically instead of mailing.
I lost my personalized GST34-2 return — what should I do?
Call the CRA business enquiries line at 1-800-959-5525 and request a replacement. The personalized return carries your account information and the correct pre-printed mailing address, so it is better to wait for a replacement than to improvise with a blank form and a guessed address.
Can I mail a cheque with my paper GST/HST return?
Only for smaller balances. Payments of $10,000 or more must be made electronically or at a financial institution. For amounts under that threshold you can enclose a cheque payable to the Receiver General, with your business number written on it.
Does PostPal check whether I am eligible to paper-file?
No — PostPal prints and mails whatever you upload, and it cannot verify your filing eligibility. Confirm with the CRA that you are permitted to file on paper before mailing. Once you are sure, it is $6 flat, printed and deposited with Canada Post the next business day, no account needed.
