Updated Checked by the Tax-Services.ca editorial team How we check
The Sudbury tax office most people mean is the CRA’s Sudbury tax centre at 1050 Notre Dame Avenue, and the CRA’s page on tax services offices and tax centres lists it as a mailing address, not as a place to walk in. Returns go to postal code P3A 5C2, and other letters go to Post Office Box 20000, Station A, P3A 5C1. Almost everything you’d mail there can be done online instead.
What is the CRA Sudbury tax centre mailing address for?
It’s where paper returns and CRA mail get processed. The CRA’s address page shows the two mailing addresses and, next to them, a prompt to submit online instead. We couldn’t find any page that lists a public counter at that address, so don’t drive there with a shoebox of receipts.
If you’re looking for a local accountant instead, that’s a different thing. The CRA doesn’t recommend firms, and this site has no link with the CRA or any office in Sudbury. We can’t tell you who’s good. We can tell you how to check.
Should you still mail a paper return?
You can, but think twice. Paper is slower, and a lost envelope is your problem. The CRA’s own notice of assessment timing is about two weeks for electronic filing, and paper takes longer. If you must mail, use tracked post, keep a photocopy of every page and write the address exactly as listed above. Returns and other letters go to different addresses, and mixing them up is a good way to add a few weeks.
Where should a Sudbury resident go for free tax clinic or other tax help?
Three routes work for most people.
First, CRA My Account and the CRA phone lines answer questions about your own file: slips, balances, notices. Second, a free tax clinic, if your income is modest and your return is simple. Clinics are hosted by community organizations under the CRA’s volunteer program, and the CRA page explains the drop-off and appointment options. We’re leaving out income limits because they differ between CRA pages. Read the current one.
Third, a paid preparer. The CRA says to use its directory of certified EFILE providers, to review the electronic return yourself and to sign Part F of Form T183 before anything is sent. Keep the T183 with your slips for six years.
What does tax cost a Sudbury employee?
Sudbury is in Ontario, so the Ontario rates apply. These figures come from our income tax calculator for a single person with only employment income and 2026 rules.
| Salary | Income tax | CPP and EI | Left after both |
|---|---|---|---|
| $40,000 | $4,363 | $2,824 | $32,814 |
| $60,000 | $8,320 | $4,340 | $47,340 |
| $90,000 | $17,034 | $5,770 | $67,197 |
| $150,000 | $39,911 | $5,770 | $104,320 |
Why is the CPP and EI column the same at $90,000 and $150,000? Both plans have yearly earnings ceilings, and both are reached before $90,000.
Try your own pay in the income tax calculator, or see the cheque itself in the take-home pay calculator. If you expect a refund, the tax refund calculator estimates it from what your employer withheld.
When does the Sudbury office matter to you?
Mostly when you owe money or want to argue a notice. Your notice of assessment and any refund are usually processed within two weeks after filing, according to the CRA. If yours isn’t, check My Account before you call anyone. Waiting on hold for something the portal already shows is a poor use of an afternoon, and Sudbury winters are long enough already.
Paying instalments is another case. If you have self-employment or rental income, the tax instalments calculator shows what four equal payments would look like. Our data says the usual threshold is $3,000 of tax owing, with payments due on 15 March, 15 June, 15 September and 15 December, but that came from a summary of the CRA page, so confirm it there.
What does a Sudbury tax-time checklist look like?
Gather slips as they land in February. Check your CRA My Account for anything the CRA already has on file. File online, then watch for the notice of assessment. If you owe, pay by the April 30 date even if the return itself isn’t due until June 15 for the self-employed. Keep copies for six years. Dull, but it works.
How much of a raise does a Sudbury employee keep?
The table above lets you check this with subtraction. Between a $60,000 salary and a $90,000 salary, the amount left after income tax, CPP and EI rises from $47,340 to $67,197. That is $19,857 more, from an extra $30,000 of salary, or about 66 cents on each added dollar. Between $90,000 and $150,000 the amount left rises from $67,197 to $104,320, which is $37,123 on an extra $60,000, or about 62 cents on the dollar.
These figures are for a single person with only employment income, so deductions, credits or other income will move them. Use the income tax calculator with your own numbers before you decide anything about an offer or a raise.
What should you do if a mailed return or letter seems lost?
Start by checking CRA My Account, because a return that arrived may already show there. If it does not, look for your tracked-post receipt and confirm the delivery date. Then check which address you used. Returns and other letters go to different addresses, so a letter sent to the return address, or the reverse, can add weeks.
If the return is still missing, keep your photocopy and receipt and ask the CRA through its official channels how to proceed. Filing a second copy without asking can create confusion, so confirm the next step first. Next year, keep a copy of your filing confirmation so this question is easy to answer.
What did we not confirm about Sudbury?
We didn’t confirm opening hours, phone extensions or whether any CRA staff meet the public in Sudbury. We also didn’t verify any local accountant’s fees or services. Where a page might have those details, we point you to the CRA and leave the rest out.
Where the numbers come from
The addresses come from the CRA‘s page on tax services offices and tax centres. Preparer advice is from the CRA page on professional tax preparers. Tax amounts come from our engine, built on 2026 federal and Ontario rates and the 2026 CPP and EI limits.
