The CRA notice of objection deadline is set to stretch from 90 days to one year for most taxpayers, according to Budget 2026 tabled by Finance Minister François-Philippe Champagne on November 5, 2026. Global News flagged the change on November 6 as one of the practical tax measures in the budget. Today, if you disagree with a notice of assessment, you generally have 90 days from the date it was sent to file a notice of objection. Under the proposal, most taxpayers would get one year from the day the notice is sent. Individuals and graduated rate estates would get the later of that date or two years after the return’s filing due date. There is a catch: the government would also end the old practice of asking the CRA for a one-year extension. None of this is law yet. It is a budget proposal that needs a bill, a vote and royal assent. We’ll be updating this article monthly as the legislation moves and the CRA publishes guidance.
For now, nothing has changed on your file. If a notice of assessment or reassessment landed in your mailbox or My Account recently, the current CRA objection deadline still applies, and the new window will only cover assessments sent three months after royal assent. Waiting for the budget rules to kick in is a risky plan if your current deadline is close. Below, you will find a side by side comparison of the old and new rules, a likely timeline for when the change could start, a step by step guide on how to file an objection, realistic processing times, and a free calculator that shows both deadlines for your own dates. Every figure in this guide comes from the budget coverage and CRA pages listed in the sources at the bottom.

What Is Changing: Old Notice of Objection Rule vs New Rule
Under the Income Tax Act as it stands today, a taxpayer who disagrees with an assessment has to file a notice of objection within 90 days of the date on the notice. The CRA’s own guidance adds a second path for individuals: the deadline is the later of 90 days after the notice or one year after the return’s filing deadline. If you miss it, you can ask the CRA for more time within one year after the objection deadline passes, and you have to explain why you were late.
Budget 2026 simplifies this. For most taxpayers, one clean rule would apply: one year after the notice of assessment is sent. Individuals and graduated rate estates would get a longer safety net, the later of one year after the notice or two years after the filing due date for that tax year. The government says the goal is to remove a step. Canadians had to request extensions, and the CRA had to review and approve them. With a longer built in window, that paperwork goes away for both sides.
| Feature | Current rule | Proposed rule |
|---|---|---|
| Standard deadline | 90 days after the notice is sent | One year after the notice is sent |
| Individuals and graduated rate estates | Later of 90 days or one year after the filing due date | Later of one year after the notice or two years after the filing due date |
| Late objection | Apply for an extension within one year after the deadline | No extension application |
| Who decides on extensions | CRA reviews and approves | Not applicable |
| Applies to | Current assessments | Assessments sent three months after royal assent |
One detail is easy to miss. Several tax advisors point out that the end of extension requests is a tightening, even though the headline sounds generous. Under the old setup, a person who missed the cutoff could still apply and, in many cases, get a second chance. Under the new rule, the one year window is the whole window. If you plan to use the extra time, put the real deadline in your calendar on day one.
Is the One Year CRA Notice of Objection Deadline Law Yet?
No. A federal budget is a statement of intent. The measures become law only after the government introduces a budget implementation bill, the House of Commons and Senate pass it, and it receives royal assent. Budget 2026 says the objection change would apply to assessments sent on or after the day that is three months after royal assent of the enacting legislation, so the start date depends entirely on how fast Parliament moves.
There is a useful precedent. Canada’s 2025 budget implementation bill, the first one from last year’s budget, received royal assent around March 30, 2026, according to a tax news bulletin from EY. Last year’s budget came in early November too. If this year’s bill follows a similar pace, royal assent would land in spring 2027 and the one year objection window would begin to apply to assessments sent a few months after that. That is our estimate based on one prior example, not an official timetable. Minority or majority dynamics in the House, committee time and the Senate calendar can all shift it.
The same note applies to the other measures. Some changes, such as the new May 15 filing deadline, have their own start dates, and others take effect on royal assent itself. Until the bill is public, treat every date in this guide as a proposal.
When Will the New Notice of Objection Rules Start?
| Step | What happens | Status |
|---|---|---|
| November 5, 2026 | Budget 2026 tabled with the objection change | Done |
| Later in fall or winter | Budget implementation bill introduced | Not yet announced |
| Committee and votes | House of Commons and Senate review | Timing unknown |
| Royal assent | Bill becomes law | Date unknown |
| Three months after royal assent | New one year rule starts for assessments sent on or after this day | Depends on assent |
Here is a simple illustration with made up dates. If royal assent happened on April 15, 2027, the new rule would apply to assessments sent on or after July 15, 2027, and a notice sent on July 14 would still be under the 90 day rule.

Who Benefits From the One Year Window, and Who Loses Out?
The big winners are people who need time to gather paperwork. Think of a self-employed worker who finds a missing expense receipt, a family that learns a medical claim was refused, or a new immigrant who does not realize an assessment has an error until the next season. Ninety days is short when the notice arrives during a move, an illness or a busy season at work.
Who loses? People who relied on the extension safety net. Under the current rules, a taxpayer who missed the cutoff by weeks could apply for an extension within the following year. If the extension option disappears, a missed deadline would simply be a missed deadline, with no application to fall back on. The bigger the window, the more tempting it is to wait, and waiting is the main risk. Objecting early also protects your rights if the CRA is about to take collection steps, because your file is in the system.
Connected Change: CRA Could Share Large Tax Debts With Credit Bureaus
The budget pairs the objection timing with a separate measure that readers should not ignore. The Income Tax Act would be amended to let the CRA disclose tax debt information to credit bureaus, but only if the outstanding debt is more than $50,000, the assessments are not under objection or appeal, and all objection and appeal rights have expired or been used up. Similar changes would apply under the Excise Tax Act. This one is described as taking effect on royal assent.
How to File a Notice of Objection With the CRA?
The steps below reflect the CRA’s guidance and general practice for individuals today. The new deadline would not change how you file, only when.
- Read your notice of assessment or reassessment and write down the date it was sent. That date starts the clock.
- Check whether a simple fix is possible. The CRA suggests adjusting your return online or contacting the agency first if you think there is a basic error. Individuals can call 1-800-959-8281.
- Gather documents. List the facts and the reasons you believe the assessment is wrong, and collect receipts, slips, bank records or letters that support you.
- Sign in to your CRA account and choose the option to register a formal dispute, called a notice of objection. The CRA’s page says online filing gives you a case number right away.
- Alternatively, file by mail with Form T400A or a written letter that explains your reasons. Form T400A is not mandatory, but a clear written objection is.
- Keep your case number. Use it when you send more documents through the CRA’s Submit Docs service or when you phone about your file.
- Wait for an appeals officer to review your objection. They may contact you for more information.
If the objection is denied and you still disagree, the next step is the Tax Court of Canada. Spring Financial’s guide notes that you generally have 90 days after the CRA’s decision to appeal. Always confirm the latest time limits on official pages, because the budget measures do not mention Tax Court deadlines.
Notice of Objection Processing Time: How Long Does the CRA Take?
The CRA pages we reviewed did not give a guaranteed processing time, and published guides describe a wide range. Some cases settle in several months, while others take a year or longer. Complexity, the amount at stake and the CRA’s workload all matter. A one year filing window does not speed up the review; it only changes how much time you have to start.
If your objection is denied and you go to the Tax Court, the court has an informal procedure for smaller cases. Spring Financial’s summary says it applies where the loss is $50,000 or less, or the disputed federal tax and penalties are $25,000 or less per assessment, with a hearing within about 180 days of submission and a decision within about 90 days after the hearing. The general procedure is slower and carries a filing fee of $250 to $550. These details come from a third party guide, so check the Tax Court of Canada site before relying on them.
Notice of Objection Refund and Payment Schedule: What Happens If You Win?
There is no fixed payment calendar for objections, because the timing depends on when the CRA finishes the review. If the CRA agrees with you, it issues a notice of reassessment that corrects the numbers. If that creates a refund, the refund is usually paid by direct deposit or cheque after the reassessment, and the CRA generally pays interest on refunds that come from a successful dispute under its normal rules. If the reassessment lowers a balance you owed, the amount owing shrinks instead.
For planning, think in three stages. First, filing the objection, which is immediate once you submit it online. Second, the review, which can take months. Third, the reassessment and payment, which usually follows soon after the CRA reaches a decision. Do not expect a lump sum on a set date, and be careful with anyone who promises one.
What If You Miss the Notice of Objection Deadline?
Under today’s rules, you can ask for an extension, and the CRA says you can apply at the same time as you file the objection, as long as you explain why you need more time. The request has to come within one year after the objection filing deadline. The CRA does not accept every request, so a strong reason helps. Extended hospitalization is one example mentioned by published guides.
Under the budget proposal, the extension step would go away for assessments covered by the new rule. That is why the real deadline matters more than ever. If your assessment was sent before the new rule starts, the current 90 day rule and extension process still apply, so do not assume the one year window covers you.
Other Budget 2026 Tax Changes Canadians Should Know
The objection change sits alongside several other practical filing measures. The table lists the main ones reported so far, with the caveat that they are proposals.
| Measure | What is proposed | Start |
|---|---|---|
| Single filing deadline | May 15 for filing and paying, for most filers and the self-employed | 2027 and later tax years |
| Foreign property reporting (T1135) | Threshold rises from $100,000 to $200,000, simplified reporting from $250,000 to $500,000 | Taxation years ending after 2026 |
| Instalment threshold | Rises from $3,000 to $7,500 and is indexed to inflation | 2028 |
| Business income instalments | Single annual instalment by December 31 for people whose main income is business | 2028 |
| Grocery and Essentials Benefit | 50 percent top up for eligible filers, payment expected early 2027 | Dates not released |
| Flat rate deductions | No receipts needed for items such as relocation, home accessibility renovations and service dog care | Details vary |
| Productivity deduction | Businesses can deduct the full cost of eligible capital assets in the year of purchase | Details vary |
The single May 15 deadline matters for objections too. It changes the filing due date that feeds the individual deadline formula, so a calculator needs the correct due date for each tax year. For tax years before 2027, the usual dates still apply, which are April 30 for most people and June 15 for the self-employed, who still have to pay by April 30.

FAQs About the CRA Notice of Objection Deadline
What is the new CRA notice of objection deadline in Budget 2026?
Budget 2026 proposes one year after the notice of assessment is sent for most taxpayers, up from 90 days. Individuals and graduated rate estates would get the later of that date or two years after the filing due date.
Is the one year notice of objection deadline in effect now?
No. It is a proposal. It would apply to assessments sent on or after the day that is three months after royal assent of the enacting legislation, and no royal assent date has been set.
How long do I have to file a notice of objection right now?
Generally 90 days from the date on your notice of assessment. Individuals can also use one year after the filing due date if that is later.
Can I still ask the CRA for an extension?
Under current rules, yes, within one year after the objection deadline, with a reason. The budget proposes to end extension requests for assessments covered by the new rule.
What happens after I file an objection?
You get a case number, an appeals officer reviews your file and may contact you, and the CRA either agrees, partly agrees or confirms the assessment. You can then appeal to the Tax Court of Canada if you disagree.
Does filing an objection stop collection of a large tax debt?
We did not find a CRA statement on this in the pages we reviewed, so ask the CRA directly. The budget does say that tax debts over $50,000 could only be shared with credit bureaus once objection and appeal rights are exhausted.
How many days do you have to object to a CRA assessment?
Today it is generally 90 days from the date on the notice, or one year after the filing deadline for individuals if that is later. The budget would lengthen it to one year for most taxpayers.
Can I object to a CRA assessment after the deadline?
You may apply for an extension within one year after the deadline under current rules. The CRA reviews each request and may refuse it.
How long does a CRA notice of objection take?
Published guides say several months to a year or longer. The CRA pages we checked did not promise a fixed time.
What is the difference between a notice of objection and a Tax Court appeal?
A notice of objection goes to the CRA first for a review. A Tax Court appeal comes after the CRA confirms its decision, and the guide we reviewed says you generally have 90 days to file it.
Conclusion: What to Do About the CRA Notice of Objection Deadline
Budget 2026 offers a real improvement for taxpayers who need more time to dispute a bill, and it would also remove the old extension safety net. The proposal moves the CRA notice of objection deadline from 90 days to one year for most taxpayers, with a longer option for individuals and estates, but it will only reach assessments sent three months after royal assent.
If you hold a notice today, treat your current 90 day or filing based deadline as the real one and file early. If you are planning ahead, use the calculator, keep your notice dates and watch for the budget implementation bill. As the legislation moves, we will keep updating the dates and details here.
