The retired government pensioner's pension and income from agricultural  sources will be excluded from the total annual income of the family while computing the income of the family members.

If his income from fixed deposits and interest income earned on the investment of PF and gratuity amount and the income out of the contractual employment (considered as private employment) exceed the threshold limit of Rs. 8 lakhs per annum for the last the consecutive three years, then you may not be eligible for OBC NCL category reservation. 

- As per law, a Government Employee of Class III or below class 3 officers are eligible for OBC Quota., and the salary/ income of the government employees are not to be taken into consideration for considering the OBC NCL category certificate.

- Since your father was working under Class III , then even his tenure of job , you was entitled to get the non-creamy OBC Certificate.

- Hence, the same status will continue after the retirement of your father and his present income from the pension will not considered , and hence you are entitled for getting OBC-NCL certificate. 

You are entitled to OBC NL certificate as your father was retired state govt employee and at age of 40 was not class I officer 

2) his pension is not included in determining your non creamy layer status 

Dear Client,

OBC NCL status is based on the job of parents or income, these marks are not decided discursively. Job is not only parameter. let’s say if your father get a class I Promotion after age of 40 then he will also be coming under as Non-Creamy Layer. Thus, as per this criterion you are still OBC Non-Creamy Layer. According to latest rules, Income limit for the unreserved candidates with no disability is Rs 8 lakh per annum. However, income from salaries & the agriculture land shall not considered as counting this revenue. It only does not consider revenue from incomes like business, professional income and other revenues. There is no income limit included for pension. This is because the pension counts as income, and any amount of salary will be excluded from deciding your apparent status for NCL purposes. Interest Income on Provident Fund, Gratuity and other saving may be included while calculating the limit of income. Nonetheless, this might only drive the overall income over Rs. 8 lakh thresholds (based on quantum of investment). Earnings of a contractual job even in the same govt department would be invariably salary income so. This should not affect your eligibility as salary income is excluded from the criteria of NCL. If the total interest income from PF, gratuity & savings is less than 8 lakh pa you may come under the scope of OBC NCL.
