Practical Examples

Let’s see how this works with some real numbers for the 2025 tax year.

• Employee UI & Workforce Development Taxable Wage Base: $43,300
• Employee TDI & FLI Taxable Wage Base: $165,400

Example 1: Calculating for a New Employee

An employee earns $1,500 per week and has earned $3,000 year-to-date. The employer’s UI rate is 2.9825% and the TDI rate is 0.5%.

• Employee Deductions:
  • UI: $1,500 x 0.3825% = $5.74
  • TDI: $1,500 x 0.23% = $3.45
  • FLI: $1,500 x 0.33% = $4.95
• Employer Contributions:
  • UI: $1,500 x 2.9825% = $44.74
  • TDI: $1,500 x 0.5% = $7.50
  • Workforce Development: $1,500 x 0.1175% = $1.76

Example 2: Calculating for a High-Earning Employee

An employee earns $2,000 per week and has already reached the UI taxable wage base but not the TDI or FLI one. Their YTD earnings are $45,000. The employer’s UI rate is 2.9825% and the TDI rate is 0.5%.

• Employee Deductions:
  • UI: $0 (since YTD wages exceed the $43,300 wage base)
  • TDI: $2,000 x 0.23% = $4.60
  • FLI: $2,000 x 0.33% = $6.60
• Employer Contributions:
  • UI: $0 (since YTD wages exceed the $43,300 wage base)
  • TDI: $2,000 x 0.5% = $10.00
  • Workforce Development: $0 (since YTD wages exceed the $43,300 wage base)
