In the United States, “state income tax” refers to personal income tax levied at the state level, in addition to federal tax. As of 2026, several states do not levy a state-level personal income tax.
In Canada, provinces collect provincial income tax. In Ontario, provincial personal income tax is a major source of government revenue.
So the policy question is not abstract. It is practical:
If personal income tax is eliminated or dramatically reduced, how does the government replace that revenue?
Why Supporters Call It Smart Policy
1. Higher Visible Take-Home Pay
Reducing or eliminating income tax directly increases net pay.
For employees, that’s immediate cash flow relief.
For sole proprietors or contractors taxed personally, lower income tax can materially change after-tax earnings.
2. Competitive Positioning
Lower income taxes are often framed as a growth strategy. Advocates argue it may:
- Attract skilled workers
- Encourage business formation
- Draw investment capital
The theory: lower tax burdens stimulate economic activity that partially offsets lost revenue.
3. Simplification (In Theory)
Some reform proposals pair elimination with fewer brackets and fewer credits.
However, simplification is not automatic. Complexity can reappear elsewhere—through exemptions, rebates, and offset programs tied to replacement taxes.
Why Critics Call It a Costly Gamble
Income Tax Is a Major Revenue Source
In Ontario, personal income tax has been reported as the largest provincial revenue stream—approximately $50+ billion in recent fiscal years.
Eliminating a revenue source of that magnitude requires significant replacement measures.
Tax Burden Rarely Disappears—It Shifts
When income tax declines, governments typically rely more heavily on:
- Consumption taxes (sales/VAT)
- Property taxes
- Excise taxes (fuel, alcohol)
- Business levies
- User fees and permits
- Spending reductions
- Borrowing
“No income tax” does not automatically mean “low tax.” It often means “different taxes.”
Regressivity Concerns
Consumption taxes apply uniformly at checkout. Lower-income households typically spend a higher percentage of income on taxable goods, which can make consumption-heavy systems regressive.
Exemptions and credits can offset this—but they reintroduce complexity.
Service-Level Risk
If replacement revenue underperforms projections, governments may reduce spending.
Cuts may appear as:
- Longer wait times
- Deferred infrastructure maintenance
- Reduced program growth
- Lower funding increases rather than absolute cuts
These changes can affect households, workforce stability, and local business environments.
Where Would the Money Come From Instead?
If income tax disappears, replacement usually falls into one or more of the following categories:
Higher Consumption Taxes
Often the most direct alternative—but politically sensitive due to visible household impact.
Higher Property Taxes
Impacts homeowners and landlords, with potential downstream effects on rent and commercial leases.
Higher Corporate Taxes or Business Levies
Intended to shift burden toward business—but can influence investment decisions, pricing, and competitiveness.
Spending Cuts or “Efficiency Savings”
Governments frequently cite efficiencies. The scale required to replace large revenue streams can be challenging.
Borrowing
Debt can temporarily bridge funding gaps, but increases long-term interest obligations.
What Research and Real-World Cases Suggest
Major tax restructurings function like real-world economic experiments.
One widely cited example is Kansas’ 2012 tax reforms, which significantly reduced income taxes and exempted certain business income. Subsequent research and policy reviews found limited evidence of broad economic acceleration, while fiscal pressures increased and portions of the reform were later reversed.
The lesson is not that every reform fails—but that large revenue gaps require realistic modeling, not optimistic growth assumptions.
What This Means for Ontario Households
Even when debates originate elsewhere, the trade-offs apply universally.
If You’re an Employee or Family
Ask:
- Would overall tax burden fall—or shift?
- Would higher sales or property taxes offset income tax savings?
- Would service access change?
A headline benefit may look different after total cost-of-living adjustments.
If You’re Self-Employed
Income volatility matters. High-income years benefit from lower income tax. But higher consumption taxes or business fees apply in lean years as well.
Demand sensitivity also matters if consumer costs rise.
If You Own an Incorporated Business
Consider:
- Interaction between corporate and personal tax
- Compensation strategy (salary vs. dividends)
- Consumer demand if sales taxes increase
Potential changes to business levies
A Step-by-Step Framework to Evaluate Any Proposal
When reviewing income tax elimination proposals, use this structured approach:
1. Clarify Scope
- Personal income tax only?
- Corporate tax included?
- Capital gains affected?
2. Identify Replacement Mechanisms
- Sales tax increase?
- Property tax change?
- Spending cuts?
- Debt issuance?
If replacement details are vague, risk increases.
3. Review Distribution Effects
Examine impacts across:
- Income levels
- Renters vs. homeowners
- Small vs. large businesses
4. Evaluate Timeline
Phased changes can create temporary mismatches between benefits and service impacts.
5. Stress-Test Your Situation
For households:
- Estimate income tax savings
- Estimate increased consumption/property costs
For businesses:
- Model demand sensitivity
- Model cost structure changes
If the plan works only under best-case growth assumptions, proceed cautiously.
Common Debate Pitfalls
- Assuming “no income tax” equals lower overall taxes
- Ignoring service implications
- Focusing on short-term gains over long-term sustainability
- Overestimating economic growth offsets
- Treating households and businesses as if impacts are identical
FAQ
Is eliminating income tax always beneficial?
Not necessarily. Outcomes depend on replacement strategy, fiscal discipline, and economic response.
Which U.S. states have no state income tax?
As of 2026, several states operate without state-level personal income tax, though they collect revenue through other mechanisms.
Would spending simply be reduced to compensate?
Spending reductions are possible but often politically and practically constrained.
Would small businesses benefit the most?
Impacts vary. Some may see higher take-home income; others may face weaker consumer demand or higher business levies.
Could Ontario eliminate provincial income tax?
Personal income tax represents a significant revenue stream. Eliminating it would require substantial replacement measures.
Bottom Line: Smart Policy or Costly Gamble?
Eliminating state income tax is politically appealing because it is easy to understand and personally visible.
But sound tax policy is less about eliminating a line item and more about how governments fund services sustainably and how the tax burden shifts across households and businesses.
If you are budgeting for your household or running a small business in Ontario, the practical approach is simple:
- Look beyond the headline
- Identify the replacement revenue
- Model your real-world impact
- Plan conservatively until details are clear
