Questions about this tool
Does every deduction reduce tax by 22%?
No. The illustration uses 22% for a qualifying deduction against ordinary income; tax rules and limits vary.
Does this check whether I qualify?
No. Confirm eligibility and documentation with the Tax Administration.
Is this the tax refund amount?
No. It estimates one possible tax effect, not your total tax or refund.
Why do I enter salary?
Salary provides a simple upper bound for the deduction illustration; it is not a full tax calculation.
