Late & Back Tax Return Filing in Ontario

Accurate, compliant and tax-efficient late & back tax return filing for individuals and businesses across Ontario — delivered by BOMCAS Canada, professional tax accountants.

Late & Back Tax Return Filing in Ontario

BOMCAS Canada helps individuals, families, self-employed people and corporations across Ontario file late and back tax returns and get fully caught up with the Canada Revenue Agency (CRA). If you have one missed return or many years of unfiled taxes, you are not alone, and the situation is almost always fixable. Our role is to take the stress and uncertainty out of catching up: we reconstruct your records, prepare every outstanding year accurately, and deal with the CRA on your behalf so you can move forward with a clean slate and genuine peace of mind.

Falling behind on tax filing happens for countless understandable reasons — a business that grew faster than its bookkeeping, the loss of a loved one, illness, a marriage breakdown, time spent abroad, lost paperwork, or simply the anxiety that builds the longer a return goes unfiled. Whatever the cause, the worst thing you can do is continue to wait. Interest and penalties compound over time, and the CRA has broad powers to assess returns for you (an “arbitrary” or notional assessment) that rarely work in your favour. The sooner you act, the more options you have — and the more we can do to reduce what you owe.

Who we help get caught up

Our late and back-filing service is built for a wide range of Ontario taxpayers, including:

  • Individuals and families with one or several years of unfiled T1 personal returns.
  • Self-employed people and sole proprietors who need business income reconstructed and reported correctly.
  • Incorporated businesses with overdue T2 corporate returns, often alongside catch-up bookkeeping.
  • Landlords and investors with unreported rental or investment income.
  • People with GST/HST or payroll arrears who have fallen behind on remittances and filings.
  • Newcomers, emigrants and returning residents with complex residency and reporting histories.
  • Estates that need multiple years brought current before a clearance certificate can be obtained.

What happens if you do not file

Unfiled returns do not simply disappear. Where the CRA believes you owe money, it can charge a late-filing penalty (commonly 5% of the balance owing plus 1% per month, and higher for repeat occurrences), apply compound daily interest on unpaid amounts, withhold benefits and credits such as the GST/HST credit and Canada Child Benefit, and issue an arbitrary assessment based on the information it has — frequently overstating your true liability. Continued non-compliance can escalate to collection action. The encouraging news is that filing voluntarily and proactively, with professional help, is exactly what stops this cycle and often unlocks relief.

The Voluntary Disclosures Program (VDP)

For taxpayers who have not yet been contacted by the CRA about the missing returns, the Voluntary Disclosures Program can be a powerful route to getting compliant. A successful application made before the CRA initiates action may provide relief from penalties and partial interest relief, and protection from prosecution, in exchange for coming forward, filing the outstanding years and paying (or arranging to pay) the tax owing. The VDP has specific eligibility conditions — the disclosure must generally be voluntary, complete, involve a penalty, and include information that is at least one year overdue. Because eligibility and strategy matter enormously, we assess whether the VDP is appropriate for your circumstances before proceeding, and we prepare the application carefully to give it the best chance of acceptance.

How our back-tax filing process works

We have guided many Ontario clients from years of anxiety to a fully current, compliant position. Our process is methodical, confidential and judgement-free:

  • 1. Confidential consultation. We listen, understand how many years and which filings are outstanding, and explain your options — with no judgement and no obligation.
  • 2. CRA account review. With your authorisation, we review your CRA records to confirm exactly what is missing and retrieve available slips and prior assessments.
  • 3. Record reconstruction. Where documents are missing, we help rebuild income and expense records using bank statements, invoices and other sources — often combined with catch-up bookkeeping.
  • 4. Strategy and VDP assessment. We determine the best path forward, including whether a Voluntary Disclosures Program application is appropriate.
  • 5. Accurate preparation of every year. We prepare all outstanding personal or corporate returns correctly, claiming every credit and deduction you are entitled to.
  • 6. Filing and CRA liaison. We file the returns, communicate with the CRA on your behalf, and work to minimise penalties and interest.
  • 7. Payment arrangements and relief. If a balance is owing, we help you request taxpayer relief where available and negotiate a manageable payment arrangement.

Reducing penalties and interest

Beyond the VDP, the CRA’s taxpayer relief provisions allow the cancellation or waiver of penalties and interest in certain situations — such as serious illness, the death of a family member, a natural disaster, or financial hardship. We assess whether you qualify and prepare a well-documented relief request on your behalf. Even where full relief is not available, filing accurately and promptly almost always produces a better result than leaving the CRA to assess you arbitrarily, and we make sure every legitimate deduction and credit is claimed across all the years we prepare.

Catch-up bookkeeping for business back taxes

For business owners, late corporate returns usually go hand in hand with incomplete books. We provide complete catch-up bookkeeping and financial statement preparation so that your overdue T2 returns, GST/HST and payroll filings rest on accurate, defensible numbers. Bringing everything current at once is far more efficient than addressing each problem in isolation, and it positions your business for clean compliance going forward.

Answers

Yes. We regularly prepare and file several years of overdue personal or corporate returns together. We review your CRA account, reconstruct any missing records, and prepare each year accurately so you become fully compliant in one coordinated process.
The Voluntary Disclosures Program (VDP) lets taxpayers who have not yet been contacted by the CRA come forward to correct or file overdue returns, potentially with relief from penalties and partial interest, and protection from prosecution. Eligibility depends on the disclosure being voluntary, complete and at least one year overdue, among other conditions. We assess whether the VDP is right for you before applying.
Filing voluntarily and proactively is the best way to limit penalties and interest, and it stops the CRA from assessing you arbitrarily. Relief may be available through the VDP or the CRA taxpayer relief provisions in circumstances such as illness, bereavement or financial hardship. We work to minimise what you owe and request relief where you qualify.
