Additional Voluntary Contributions are extra funds you can opt to add to your mandatory pension contributions, or simply set aside as retirement savings. These funds would be deducted from your monthly emolument by your employer and remitted into your Retirement Savings Account (RSA), along with your regular pension contributions.
AVC differs from other regular savings you may have, as it is deducted from your salary before tax. This is a significant advantage of the AVC, as it means the contributions are tax-free and lower your overall tax liability.
