PF rules are still same, and maintain 15000 capping,
However the department would keep an eye on records of the employees, who draw gross wages below 15000/- that the diff of gross wages and EPF wages paid is segregated on genuine facts or not. if found incorrect then they would seek contribution on that portion of payment
new wages code is not just for PF, its gross effect would be on annual income tax (TDS), where most of the allowances may get taxable, and terminal benefits would be higher for the employee side, viz gratuity, EL encashment etc
