Who is affected by the ₹2.5L taxable interest rule: If your basic salary is above ₹1,73,611/month (₹2.5L ÷ 12 months ÷ 12% contribution): your EPF contribution exceeds ₹2.5L per year. Interest on the excess is taxable. Example: Basic ₹2L/month → EPF contribution ₹2,40,000/year (under ₹2.5L) → all interest tax-free. Basic ₹3L/month → EPF contribution ₹3,60,000/year → interest on ₹1,10,000 excess is taxable at slab rate. EPS, Employees Pension Scheme: Part of employer's 12% contribution goes to EPS (8.33%, capped at ₹15,000 basic = ₹1,250/month for old scheme, uncapped under higher wage option). EPS gives pension on retirement, minimum ₹1,000/month. No return during accumulation period, it's an annuity pool. Cannot be withdrawn separately, it's converted to pension at age 58. UAN, Universal Account Number: Permanent account number for EPF. Stays with employee across all employers.
