Depending on which city you are in, the proportion of individuals and units in general provident fund payment is the same.
For example:
Proportion of social security accumulation fund in Shanghai: the lower limit of social security accumulation fund base is 2 140 yuan, and the upper limit is 10698.
4 gold (five insurances and one gold):
Individuals: pension 8%+ medical care 2%+ unemployment 1%+ provident fund 7%= 18%.
Unit: Pension 22%+ medical care 12%+ unemployment 2%+ maternity 0.5%+ work injury 0.5%+ provident fund 7%=44%.
It can be seen that in Shanghai, provident fund means that all individual units pay according to the proportion of 7%, while in Beijing, both parties pay according to 12%.
Personally, I think your salary level can be paid in full, the basic level is about 2000. After all, it is good to pay more provident fund, because you can pay as many companies as you want, and you can use it when you need it in the future. Short-term benefits are relatively strong, unlike benefits such as pensions, which are long-term guarantees.
At present, you have paid social security for one year according to the base, and the provident fund should be independent. If you can make up, the company is willing to give you more, maybe, but generally the social security and provident fund of the same employee will not be calculated according to different proportions, so you can only go to the local provident fund acceptance center to check whether you can make up. Ask the company: 3. Whether the company is willing to pay back according to a base different from social security. Yes, and then you can hand it in.
I hope I can help you. I've been bothered by these for a long time, too.
