i little confused about my PF they are mentioned in CTC pf contribution is Rs 1800/- only…as per PF rule is in basic 12% …how would it come rs 1800/- can you please explain on this 1800/-…tq

The PF rule is 12% of 15000 (=1800) as minimum value for calculation. Your basic may be higher than this but your company can decide to pay you minimum (i.e. 12% of 15k) or 12% of actual basic.
