- {{gross-wages}}: The employee's gross wages for the pay period.
- {{tax-rate}}: The applicable tax rate (e.g., 20%).
- {{deductions-list}}: A list of post-tax deductions, including amounts (e.g., union dues $50, charitable contributions $25).
Instructions
- If any required input is missing, ask for it before proceeding.
- Calculate the total taxes on the gross wages using the provided tax rate.
- Subtract the taxes from gross wages to get the after-tax amount.

- Use a professional and precise tone.
Guardrails
- Do not assume additional deductions beyond those listed.
