Canada’s tax system has reached a point where complexity is getting in the way of day-to-day administration at the Canada Revenue Agency. New regimes have piled up while older rules stay on the books. The agency is missing basic service standards, taxpayers are frustrated, and accountants are calling for a full review of the system.
The Weight of Legislative Bloat
The Canadian tax code has grown into a structure that few people can navigate without professional help. Over the last decade, governments have added regimes such as the underused housing tax, luxury taxes, and a rewritten alternative minimum tax, without clearing out older rules that overlap. That stacking creates work for the taxpayer and for the agency that has to apply the rules. When the law is too tangled to explain clearly, the CRA cannot administer it with consistency or speed.

Service Failures and Declining Accuracy
The strain shows up in the agency’s own numbers. Auditor General reports have found the CRA struggling with core service. Only 18 percent of calls to contact centres are answered within the 15-minute standard, and the accuracy of the information given on those calls has fallen to 17 percent. Those figures describe a breakdown: the agency is often unable to give reliable guidance on the rules it enforces.
The current tax system is bloated and inefficient, requiring the first comprehensive tax review since the Carter Commission to restore public trust and administrative functionality.

The Rise in Taxpayer Frustration
Taxpayers are saying so. The Taxpayers’ Ombudsperson reported a 27 percent increase in complaints against the CRA in the 2025–2026 fiscal year. The surge is driven less by the size of the tax bill than by processing delays and unclear answers. The complaint volume is being fed by:
- Long processing times for ordinary returns.
- Different CRA agents giving different answers on the same question.
- New reporting rules that are poorly explained.
- Long waits to fix simple administrative errors.
- Little visibility into the status of a pending file.
The Call for a Carter-Style Review
CPA Canada and other professional bodies argue that small patches will not fix this. They want a comprehensive review on the scale of the Carter Commission, whose report landed in 1966. The aim would be a simpler code, fewer overlapping provisions, and rules the CRA can actually administer. Without that shift, the agency will keep struggling, and the burden on taxpayers will keep growing.

Frequently Asked Questions
Why is the CRA struggling to answer calls?
New and overlapping tax rules lengthen calls and raise the number of questions agents are not equipped to answer accurately.
What is driving the processing delays?
Several complex tax layers now require checks that do not have clear, automated guidelines.
When was the last full tax review?
The last comprehensive review was the Carter Commission, which reported in 1966. Accountants argue the current system needs a review of that scale.
