What is a CRA notice of objection?
A notice of objection is the formal way to dispute a CRA assessment or reassessment. It sends your file to CRA's Appeals Branch, which reviews it independently of the auditor and can confirm, change or cancel the assessment. For income tax it's filed online or with Form T400A, and for GST/HST online or with Form GST159.
Can a CRA reassessment be reversed?
Yes. Appeals can cancel or reduce a reassessment when the facts, the law or the calculations don't support it. Common examples are input tax credits denied over paperwork that other records cover, bank deposits counted as income that were never income, and penalties CRA can't prove.
How long do I have to file a notice of objection?
For corporations, GST/HST and payroll assessments, 90 days after the date CRA sent the notice. Individuals have until the later of 90 days after the notice or one year after their filing due date for that tax year. Count from the date printed on the notice, not the day it arrived.
How do I file a notice of objection with CRA?
Online through My Business Account, My Account or Represent a Client, using the formal dispute option, or by mail using Form T400A for income tax or Form GST159 for GST/HST. Set out each issue you disagree with, the facts and reasons, and attach the documents that support your position.
What should a notice of objection include?
Each adjustment you disagree with, the result you're asking for, the relevant facts, the reasons under the law, and the supporting documents. Objections that only say you disagree rarely succeed. Large corporations must also describe each issue and the amount of relief sought, and are limited to those issues if the file goes to court.
I missed the 90-day deadline. Can I still object?
Often, yes. You can apply for an extension of time up to one year after the objection deadline. You'll need to show that you intended to object on time or couldn't act, that you applied as soon as circumstances allowed, and that granting it is just and equitable. File the objection together with the request.
Do I have to pay CRA while my objection is under review?
For income tax, CRA generally can't collect the disputed amount until 90 days after Appeals decides, although large corporations pay half and payroll withholdings aren't postponed. GST/HST is payable right away, and CRA can collect it while you object unless it agrees to postpone collection or accepts security. Interest runs either way, so some businesses pay and object at the same time.
How long does a CRA objection take?
CRA publishes average processing times every month. Recently, simpler income tax objections have averaged around four months, and medium-complexity files, which include most business disputes, around a year. If Appeals hasn't decided within 90 days for income tax or 180 days for GST/HST, you can take the matter to the Tax Court instead.
What's the difference between a proposal letter and a notice of reassessment?
A proposal letter comes during the audit and sets out changes CRA intends to make. You respond to it, usually within 30 days, but you can't object to it. A notice of reassessment is the decision itself, and it's the document that starts the objection clock.
Can CRA reassess a year after three years?
CRA can normally reassess within three years of the original notice for individuals and Canadian-controlled private corporations, and four years for other corporations. For GST/HST, the limit is generally four years from when the return was due or filed. After that, CRA must show a misrepresentation due to carelessness, neglect or wilful default, or fraud, and the burden of proof is on CRA.
CRA ignored the documents I already sent. What now?
Resending them to the same area rarely helps. A formal objection moves the file to an appeals officer who reviews it independently. Attach the documents and explain which adjustment each one answers. If the problem is a payment CRA didn't apply, ask for a payment search first, since that's usually faster.
Can I object to a penalty but not the tax?
Yes. An objection can target the tax, the penalty, or both. For a gross negligence penalty, CRA has to prove the facts that justify it. Penalties and interest can also be addressed through a separate taxpayer relief request on Form RC4288.
Can filing an objection make my assessment worse?
It can. If the year is still within the normal reassessment period, CRA can look at other items while reviewing the file. That's why we check the file for exposure before anything is filed.
What happens if Appeals confirms the reassessment?
You have 90 days from the notice of confirmation to appeal to the Tax Court of Canada. Smaller disputes can use the informal procedure, which is simpler and has no filing fee. Larger or more complex appeals use the general procedure, where a corporation is normally represented by a lawyer.
Do I need a tax lawyer or a CPA for a CRA objection?
Most objections turn on facts, records and calculations, which is accounting work, so a CPA with audit experience is often the practical choice at the objection stage. If a file is headed for the Tax Court's general procedure or there's any criminal exposure, a tax lawyer should be involved. Communications with a lawyer can be privileged, while communications with an accountant generally aren't. We work alongside counsel when a file needs it.
