After you file

You wouldn't actually claim yourself as a "dependent". However, if you pay over half of your own support, then nobody else can claim you as a dependent on their tax return and you will get the Personal Exemption amount on your own tax return.  The Personal Exemption amount is $4,050 for 2016 and is the amount someone would be able to deduct on their tax return for each qualified dependent they claim.

Support includes:

  • Food
  • Lodging (even if your mortgage is paid off)
  • Clothing
  • Education (including the GI bill)
  • Medical and dental care (including insurance and supplementary Medicare premiums)
  • Recreation
  • Transportation and similar necessities

Support does not include:

  • Life insurance premiums
  • Funeral expenses
  • Federal, state, or local income taxes or Social Security and Medicare taxes paid on a person's own income
  • Scholarship grants
  • Income made by a disabled person in a sheltered workshop
