Separate the exemption from the voluntary option
Not contributing does not breach the mandatory non-citizen EPF rule when the worker is a domestic servant. The question is whether the helper and employer both choose to enter the optional arrangement.
Discuss the effect on gross salary, employee deductions, employer cost and long-term savings before signing anything. Record the decision rather than making an informal deduction.
Resolve the overlapping form categories before payroll
EPF’s option page identifies KWSP 16 for domestic helpers and KWSP 16B for foreign citizens. A foreign domestic helper falls within both descriptions, so give EPF the worker’s citizenship, domestic-worker status, age and existing member status and ask which form and contribution table apply.
Once EPF confirms the route, keep the accepted form, member number, contribution month, employee share, employer share and payment receipt with the salary record. If you are still weighing whether to opt in, you can talk it through over WhatsApp before either party signs.
