Dear Sir

The eligibility criteria for obtaining a non-creamy layer certificate has been listed below:

1. A person belonging to non-creamy layer category (i.e. parent's income is below Rs. 8 Lakhs) can only apply for this certificate.
2. If anyone of the person's parents is working under Group C and D officer category of the Central Government or under Group II, III and IV officer's category of the Tamil Nadu State Government then he/she will be eligible to apply for the certificate.
3. If a person is working under Group B officer category of the Central Government or Group I of the Tamil Nadu State Government then he/she is eligible to obtain the certificate provided that his/her parents do not receive any kind of income.
4. If the applicant's husband is working under Central Government, his wife is eligible to apply for OBC certificate provided that the wife’s parents do not receive any kind of income.

The people who are not eligible to apply for this certificate are as follows:

1. Certain castes that come under Backward Caste and Most Backward Caste who are not included in the Central Government’s OBC category cannot apply for this certificate.
2. If parents of the applicant are employed under Group A services like IPS, IAS, and IFS he is not eligible to apply for this certificate.

OBC creamy and non-creamy layer income limit

The applicability of the OBC certificate is based on the income of the household. Apart from the annual income, if the parents are receiving any other income, then that income will also be considered to consolidate the sum of Rs. 8 lakh. The income received by parents who are working in the private sector will also be considered for consolidating the total amount. Income received from farming and agricultural activities will not be taken into account for evaluating the eligibility.
 
Therefore, if you fall under the criteria for eligibility listed above, the non-creamy layer quota will be applicable to you.

NO, you are crossing income limit.

If your father is an government employee and he do not belong to the class I or group A category especially if he was not recruited to class I or Group A  nor he was promoted to that post before attaining 40 years of age, then you will be eligible for the privileges under OBC NCL category reservation.

The salary income is not taken into consideration  for computing the annual income of the family, hence his salary income even if it is beyond Rs. 8 lakhs per annum, you are eligible to the said reservation.

OBC Creamy layer—-Who has yearly income more than 8 lakhs or Government Employees of greater than class 3 are not eligible for OBC Quota.  

OBC Non-Creamy layer—– Who has a yearly income below 8 lakhs or Government Employees of Class 3 or below class 3 officers are eligible for OBC Quota.
