Worked Example

Let's calculate the tax for a single individual with $50,000 in taxable income:

First $44,701 at 5.05% = $2,263.50
Next $5,299 at 9.15% = $483.50
Remaining $2,979 at 11.16% = $332.50
Total tax = $2,263.50 + $483.50 + $332.50 = $3,079.50

This example shows how the tax is calculated across different brackets. The actual tax you owe may vary based on your specific circumstances.
