Yes, you can claim your dad even though he passed away in 2016 per the following qualifications below:

• You provided more than half of his support in 2016

•  He lived with you 365 days in the year or is related to you.
•  He isn’t a dependent on someone else’s tax return..
• He isn’t filing a tax return with a spouse (married filing jointly).
