Latecomers: Sort through your tax arrears before the end of the year

Introduction to Tax Relief Provisions

The Income Tax Act states that the normal period for reassessment is three years from the date on which the notice of assessment or reassessment is sent or received. However, under the tax relief provisions, it is possible to claim adjustments for errors or omissions on personal tax returns for a period of 10 years.

Understanding the 2015 Tax Year

The 2015 tax year expires after December 31, 2025, due to the 10-year tax relief provisions. This means that for the 2015 tax year, several opportunities to save tax money will no longer apply, including:

  • Tax refunds you are entitled to for the 2015 tax year
  • The ability to build RRSP contribution room for the 2015 tax year, reducing the potential for future retirement income security
  • Deductions and non-refundable tax credits associated with “carry-over amounts,” such as moving costs, medical costs, charitable donations, and political donations
  • Refundable tax credits owed, such as Canada Child Benefit, GST/HST Credit, Canada Employee Benefit, and Reimbursable Medical Expense Allowance
  • Unreported losses, including capital and non-capital losses, which are not available to offset their respective 2015 sources of income or for carryover purposes
  • The ability to use the lifetime capital gains exemption for disposals in 2015
  • AMT (Alternative Minimum Tax) carryforwards from previous years can no longer be applied to 2015

Impact on Spousal Returns

If a spouse fails to file, it means that household income is not being properly reported for means-tested purposes. If the timely filing spouse did not accurately estimate his or her missing spouse’s net income, it is possible that some of the tax benefits received by the timely filing spouse may have to be repaid in the event of a CRA audit and/or the taxes payable may be increased.

Provincial Tax Credits and Pension Splitting

Different rules apply to provincial tax credits. Not all provisions on the federal T1 return qualify for a 10-year correction for errors or omissions. In most provinces, only the normal reassessment period for federal returns is available for these purposes – three years from the date of the original return. In Quebec, this reassessment period is four years. Additionally, pension splitting with your spouse has different filing rules, and optimizing retirement income splitting or joint elections to implement income splitting on Form T1032 only applies to a three-year window.

Beware of Losing Benefits

It is only possible to go back 11 months to claim missed non-deferred retirement benefits (OAS), unless there was a severe disability that prevented the senior from claiming the benefits. Other social benefits, such as the new Canada Dental Care Plan (CDCP) and the Canada Disability Benefit (CDB), have different rules for claiming benefits.

Claiming Missed Benefits

According to CDCP, the CRA may reconsider a claim if you file a claim within 24 months of the end of the benefit period. However, if a false or misleading statement was made, the government has 72 months (six years) to collect that tax debt from you. The CDB allows for retroactive payments for up to 24 months if you were eligible during that period, starting in July 2025.

Why Filing Late is a Bad Idea

Filing late can result in missed deadlines, penalties, and interest. Overdue tax debts can lead to hefty penalties and interest, including:

  • Gross negligence, which is a civil penalty that the CRA can levy if the CRA ignores tax filing requirements
  • Tax evasion, which carries a penalty of 200% of the taxes owed plus compound interest, plus civil penalties and up to five years in prison
  • Tax fraud, which can result in a prison sentence of up to 14 years, fingerprints, and travel restrictions abroad

Conclusion

Always remember that access to tax breaks and benefits begins with filing a tax return. Plan well before the end of 2025 to catch up on missed tax returns or request corrections for errors or omissions. Filing on time can help minimize CRA debt and potentially lead to financial freedom. It is essential to confirm with a tax professional that the taxes have been correctly assessed by the agency and pay quickly to avoid penalties and interest. By understanding the tax relief provisions and filing on time, individuals can take advantage of available benefits and avoid costly penalties.
