SSS has a 120 monthly contribution requirement
You can stop paying contribution after you make a final SSS benefit claim for total disability or retirement.
You can file for optional retirement when you’re 60 years old and unemployed. If you’re 65 or older and still working (or not), you’ll qualify for technical retirement and won’t need to pay SSS contribution.
However, voluntary members may continue paying the contribution in their retirement years. To increase their retirement benefits, voluntary members aged 60 to 65 with at least 120 posted monthly contributions may still pay until age 65.
Voluntary members aged 65 and above with less than 120 posted monthly contributions may continue paying contributions until they reach the 120-monthly contribution requirement to qualify for monthly pension.
