If EPF is already running and you want more safe, tax-efficient savings, VPF and PPF are the usual suspects. They are not identical.
- VPF: extra contribution to your EPF account at EPF rate; employer rules apply; tied to employment.
- PPF: your own 15-year account, deposit limits, fully EEE tax status, works even between jobs.
Many people use both: VPF while employed for convenience, PPF as a portable long-term base. Run current rates before you lock large sums.
