Can I claim my 19 year old sibling as a dependent?

[michoacanaburto]

Our household consists of

myself (34) and i made 22,259. brother (18 in 2017) turned 18 on january 3 and was still a high school student till graduation on june 4, 2017. while he was in school he only worked on the weekend after graduation he works full time. he is not attending college just working. He made 15,1339 in 2017. He pays his cell phone bill and the internet. and sometimes helps pay a utility here and there. he is 19 since january of this year. I have claimed him as a dependent while he has been in high school. can i still claim him as a dependent for 2017?

my father gets ssi benefits that amount to a little over 13,000 and my mother worked a seasonal job in which she made 5469. my father's benefits are not taxable. since myself and the 27 year old brother bring in higher income than either of my parents, can my parents be claimed as dependents on our taxes? 

 There is also a 15 year old brother who is claimed by the 27 year old brother as a dependent. he made around 16,000. I also claim a 20year old sister who made 6033. she is a full time student and only works in the summer when she is off school. during the school year she lives in a dorm and comes home on the weekend but i provide her support.

Possibly, your brother meets the age test of being under 19 at the end of the year, not sure about the support.

You can claim a dependent on your 2017 taxes as long the following requirements are met:

• You cannot claim a dependent if you, or your spouse if filing jointly, can be claimed as a dependent by another taxpayer.
• You can't claim a married person who files a joint return as a dependent unless the joint return is filed only to claim a refund of withheld income tax or estimated tax paid.
• You cannot claim a person as a dependent unless that person is a U.S. citizen, U.S. resident alien, U.S. national, or a resident of Canada or Mexico.
• You cannot claim a person as a dependent unless that person is your qualifying child or qualifying relative.

 Qualifying child tests

• The child is related to you as - son, daughter, stepchild, foster child, brother, sister, half-brother, half-sister, stepbrother, stepsister, or a descendant of any of them.
• The child is under the age of 19 at the end of the year (under age 24 if a student), and younger than you (or your spouse if filing jointly).
• No age limit for permanently and totally disabled children.
• The child lived with you for more than half the year (exceptions apply).
• The child provided less than half of his or her own support for the year.
• The child must not be filing a joint return for the year (unless that joint return is filed only to claim a refund of withheld income tax or estimated tax paid).
