Flat-rate parking fines disproportionately impact low-income individuals while failing to meaningfully deter wealthier violators. One way to address this inequity could be implementing income-based fine scaling, where penalties adjust based on the violator's ability to pay. This approach would align consequences with financial means, creating fairer enforcement while potentially improving compliance across income groups.

How Income-Based Fines Could Work

Instead of fixed amounts, fines could be calculated as a percentage of income (e.g., 0.1% of annual earnings) or through tiered brackets (e.g., $50 for incomes under $30k vs. $200 for over $150k). Implementation might involve:

• Secure income verification through tax agency partnerships or opt-in payroll data
• Automated calculation systems integrated with parking enforcement software
• Pilot programs using simplified bracket systems to test feasibility

Potential Benefits and Considerations

This system could reduce financial strain on low-income individuals while maintaining deterrence value across economic groups. Municipalities might see improved compliance and public trust, though administrative complexity could pose initial challenges. High-income violators may resist higher fines, suggesting the need for careful messaging about equitable enforcement benefits.

Implementation Pathways

A phased approach could start with:

1. Partnering with progressive cities for limited pilots
2. Developing tiered fine structures that balance fairness with simplicity
3. Creating automated calculation tools to minimize bureaucratic overhead

Existing models like Finland's day-fine system demonstrate this approach's viability for serious offenses, suggesting potential adaptation for parking violations.

By focusing initially on technical integration and public acceptance testing, municipalities could explore whether income-adjusted fines create more equitable outcomes without compromising enforcement effectiveness.
