When families head out for dinner, parents sometimes playfully claim a ‘Dad tax’—a small bite from a child’s appealing dish in exchange for covering the bill. Over time, children learn to order items their parents avoid, altering their choices entirely. This mirrors a core economic truth: taxes influence behavior, often yielding unexpected results.
Historical Example: The British Window Tax
One classic case occurred in 1696 when the United Kingdom imposed a tax on homes based on window count, targeting wealthier properties with more light and space. Homeowners responded by bricking up windows to lower their bills, leaving elegant Georgian homes dim and poorly ventilated. Public health issues arose, and the tax lasted until 1851. Bricked-up windows still dot British streets, serving as a stark warning about unintended tax incentives.
Modern Tax Impacts Around the World
Today, high personal tax rates in Canada discourage top earners from staying or succeeding. Similar dynamics appear elsewhere: California’s push to tax billionaires prompts their exodus, Washington’s capital gains tax adjustments for high earners spur outflows, and the Netherlands’ proposed levy on unrealized gains risks capital flight.
In British Columbia, recent tax hikes coincide with escalating government spending that outpaces economic growth, projecting ongoing deficits. The province saw net resident losses in 2023 and 2024, with more people moving to Alberta amid high taxes, housing costs, and affordability strains—a shift from prior migration trends.
Federal Fiscal Pressures in Canada
Federally, the latest budget forecasts a $78 billion deficit this year, driven by expanding program costs, with large shortfalls projected ahead. Interest on the national debt nears $55 billion annually, offering no direct public benefits. As spending grows faster than the economy, options narrow to cuts, borrowing, or tax increases—politically challenging amid affordability woes.
A Path Forward: Comprehensive Tax Reform
Economist Jack Mintz and colleagues at the C.D. Howe Institute advocate ‘Big Bang’ tax reform to boost growth, investment, and productivity. Key elements include:
- Substantial cuts to personal income tax rates
- An optional $10,000 simplified personal credit to streamline filing
- Five percent corporate tax reduction, removing preferences like the small business deduction
- An elective distribution-based corporate tax, akin to Estonia’s model, taxing profits upon shareholder payouts to spur reinvestment
To offset cuts, proposals suggest raising the GST by 2.8 points or adding a three percent employer payroll tax. Long-term gains could include $140 billion in non-residential capital, a $79 billion GDP boost (2.5 percent), and $26 billion in extra annual revenue, while maintaining redistributive equity.
Such reforms could reverse disincentives from high rates and targeted credits that hinder investment and productivity. Without change, rising deficits may fuel novel taxes, prompting adaptive behaviors much like the window tax or family dinner tactics.
