Ideally, you have no unpaid monthly contribution in your SSS account to maintain your active membership status. Once you become an SSS member, you’re covered for life, even if you miss your monthly payments. There’s no penalty for individual members who fail to pay their contribution for a certain period. However, the SSS doesn’t allow members to make retroactive payments to qualify for a loan or benefit. You can only continue paying for the succeeding months or in advance, but never for the past unpaid months. To avoid missing your SSS payments, be mindful of the payment deadline. Here are the respective payment deadlines for those who are required to contribute: Regular Employers: Last day of the month following the applicable month (e.g., the March contribution deadline is April 30). Household Employers: Last day of the month following the applicable month or calendar quarter—last day of every three calendar months (i.e., March 31, June 30, September 30, and December 31).  Self-Employed, Voluntary, or Non-Working Spouse: Last day of the month following the applicable month or calendar quarter—last day of every three calendar months (i.e., March 31, June 30, September 30, and December 31).  Land-Based OFW Members: SS Contributions for January to September can be paid until December 31 of the applicable year.   Self-Employed Persons in the Informal Economy (e.g., Farmers and Fishermen): Contributions for any of the last twelve applicable months may be paid in the current month (e.g., August 2023 contribution can be paid from August 2022 to July 2023).
