My dad used to be a soldier in the army for five years. Can he offset the five-year old-age insurance? The social security bureau in my hometown said that it can be paid for five years, but the social security for the other ten years should be paid in cash. ... Your father's five years in the army can be regarded as the payment period of endowment insurance, and other years must be the actual payment period. If your father works in Taicang and pays the old-age insurance, you can transfer the eight-year old-age insurance to your hometown and calculate the payment period of your father's old-age insurance cumulatively.
