Scientific Background
Assumptions: user-entered credits already eligibility-checked. Limitations: does not compute CTC/EITC internally—pair those calculators first. Distinct from /tax-refund-estimator which accepts fully user-entered tax before credits. Sources: https://www.irs.gov/pub/irs-drop/rp-25-32.pdf ; https://www.irs.gov/refunds
