Late and prior-year tax returns in Quebec

We help organize unfiled returns, prior years, missing slips, and CRA or Revenu Québec notices before choosing the filing order.

Start a catch-up returnAsk about late or prior years

Best when missed years, notices, missing slips, or catch-up sequencing affect the next step.

  • Human review before submission
  • Secure intake for tax documents
  • English and French

Start with the missing years

A catch-up file begins with a year-by-year picture of what has and has not been filed.

Keep records by year

Group slips and notices under the year they concern.

Explain gaps before filing

Tell us about missing documents and deadlines so the filing order can be confirmed.

Useful in Montreal and across Quebec when older federal and Revenu Québec filings have piled up, notices have started arriving, or you want a practical path to get current again.

Who this service is for

Catch-up files need a clear picture of missing years, available records, and the order in which returns should be prepared.

  • People who missed one or several Quebec tax years and want a realistic catch-up plan.
  • Filers who received CRA or Revenu Québec notices and need to understand what still has to be gathered before filing.
  • Clients whose older returns involve a mix of employee, self-employed, rental, or investment documents.

Pricing guidance

Late and prior-year returns are scoped according to how many years are missing, what documents still exist, and how varied the income picture is across those years.

  • One missing employee year does not require the same review as several mixed-income years with notices and missing slips.
  • Document retrieval, catch-up planning, and broader cleanup often increase the scope beyond a standard current-year return.
  • The pricing page gives a starting reference, but older files are priced around the real work required to make them filing-ready.

If you are unsure whether the file belongs under employee, self-employed, rental, or another category, start anyway and explain the catch-up context at intake so the scope can be set properly.

Why this service fits late and prior-year files

Missing years, notices, and document gaps are reviewed before a filing sequence is confirmed.

Built for catch-up filing in Montreal and across Quebec

This service is scoped for Quebec filing delays, missed years, notices, and mixed older records that need to be organized before the work can move in the right order.

Bilingual support for a calmer first step

TaxCove supports clients in English and French so late-filing questions, notice follow-up, and missing-record issues can be triaged before the file is treated like a normal current-year return.

A defined path after you start

Once the file enters the secure process, the next step is organizing the missing years, identifying the key records, and confirming the filing order before final preparation.

What is included

The work starts with clarifying the years, records, and notices involved so the file can move in the right order.

Year-by-year scope review

We identify which years are missing, what kind of income applies to each year, and where the file is likely to need the most follow-up.

Notice and balance review

We review the notices, requests, and prior assessments you already have so the catch-up plan is not built in the dark.

Document gap planning

If slips, receipts, or account records are missing, we flag the gaps early instead of pretending the file is ready to submit.

Practical filing sequence

We help determine a sensible order for older returns so the work is staged around the real state of the file.

Prioritize obligations and expiring claims

An unfiled year can contain a debt, a claim deadline or both.

Reference points for this file

  • The federal late-filing penalty and interest are separate. Filing a return does not pay its balance, and a zero late-filing penalty does not rule out other penalties.
  • For solidarity based on the 2022 return, Revenu Québec lists December 31, 2026 as the claim deadline. Eligibility and the complete application still matter; a late return does not guarantee payment.

What is not included

These limits keep expectations clear around tax preparation, document review, and follow-up.

Review detailed exclusions

  • This service does not promise a specific balance, filing result, authority decision, penalty treatment, or tax amount.

  • It does not replace legal representation, investment advice, financial planning, or access to government accounts that only the taxpayer or an authorized representative can manage.

  • Bookkeeping cleanup, multi-year reconstruction, objections, appeals, or extended correspondence are scoped separately when they are needed.

Documents and information to prepare

Older returns move faster when the years, notices, and available records are grouped before intake.

  • Any CRA or Revenu Québec notices, requests, balances, or statements you have already received.

  • The slips and income records you still have for each missing year, including T4, RL-1, T5, business summaries, or rental statements.

  • Prior notices of assessment and any online account screenshots or summaries that help confirm the years still missing.

  • A short timeline explaining major changes such as self-employment, rental purchases, divorce, moves, or foreign income during the missing years.

Common mistakes we help prevent

Catch-up filings become harder when people try to guess their way through several years at once.

  • Submitting a rushed current-year return without first understanding the older years that still need attention.

  • Ignoring CRA or Revenu Québec notices instead of using them to define what is actually missing.

  • Estimating older income or deductions from memory when better source records or account history should be gathered first.

  • Treating several years as if they all have the same income profile when the file changed over time.

How it works

The goal is to stabilize the file first, then move into the secure process with the right years and records in scope.

Step 1

Start the intake and list the missing years

Use the existing secure start process and tell us which tax years are outstanding and what notices or deadlines you are dealing with.

Step 2

Upload notices and available records

Share the slips, prior notices, account information, and supporting records you still have for those years.

Step 3

Clarify missing documents and filing order

We identify the biggest gaps, determine the likely sequence for the work, and flag where the scope expands beyond a simple catch-up.

Step 4

Move into the filing process

Once the years and records are clearer, we continue through the secure process with a better-defined plan instead of a vague backlog.

Frequently asked questions

Can you help if I missed more than one year?

Yes. The first step is to identify which years are missing and what records still exist so the file can be organized realistically.

What if I already received CRA or Revenu Québec letters?

Share them at the start. Those notices often help define the years involved, the balances, and the records that matter most.

Do I need every slip before I contact you?

No. You should still start the conversation, but it helps to gather the notices and whatever records you already have before intake.

Is this only for employee returns that are behind?

No. Late returns can include self-employed, rental, or mixed-income situations, which is why the intake needs context year by year.

Need a catch-up plan for missed tax years?

Use Start when the missing years are already identified

Start is the better option when you already know which years are missing and you can group the main notices, slips, and background information before intake.

Start a catch-up return

Contact first if the filing order is still unclear

Direct contact is useful if notices, mixed income types, or missing records make it hard to tell which year or service option should be handled first.
