Quick Answer

Your parents can claim you as a dependent even after you turn 18, provided they still support you financially and you meet IRS criteria for dependent children and relatives.

Your parents can claim you as a dependent on their taxes after you turn 18 if they support you financially and you meet other IRS requirements for dependent children or relatives. It's common for parents to continue to claim adult children as dependents while they're in college or still at home as they establish their adult lives.

To avoid issues with the IRS, everyone needs to coordinate on who's claiming whom and who needs to file a return. Here are a few basics to get you started.

Who Qualifies as a Dependent?

Tax dependents generally fall into two camps: qualifying children and qualifying relatives. To better understand who qualifies as a dependent, here are the requirements.

All Dependents

All tax dependents must meet the following qualifications:

  • They must be a U.S. citizen, resident alien or national, or a resident of Canada or Mexico.
  • They can't be claimed as a dependent on more than one tax return, with rare exceptions.
  • They can't claim a dependent on their own tax return.
  • They can't claim a spouse as a dependent if they file jointly.
  • They must be a qualifying child or qualifying relative, as defined below.

Qualifying Child

You qualify as your parent's dependent child if you meet these criteria:

  • Relationship: You're their son, daughter, stepchild, foster child, brother, sister, half brother, half sister, stepbrother or stepsister, or a descendant of any of these relatives.
  • Age: You meet the following age requirements:

    • You're under age 19 at the end of the year and younger than the taxpayer (or their spouse if filing jointly), or
    • You're under age 24 at the end of the year, a student and younger than the taxpayer (or their spouse if filing jointly), or
    • You're any age and permanently and totally disabled
  • Residence: You've lived with your parent(s) for more than half the year.
  • Support: You have not provided more than half of your own financial support for the year.
  • No joint filing: You aren't 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).

Qualifying Relative

If you don't qualify as a dependent child, you may still be claimed as a qualifying relative. Here are the criteria:

  1. Not a qualifying child: You are not claimed as a qualifying child by any taxpayer.
  2. Relationship or residence: You are the taxpayer's child, stepchild, foster child or grandchild, or you live with the taxpayer all year as a member of their household.
  3. Income: Your gross income for the year is less than $5,050.
  4. Support: The taxpayer provides more than half of your total support for the year.

Pros and Cons of Being Claimed as a Dependent

Though parents stand to gain more from this arrangement than their children do, adult children may be happy to exchange a few tax benefits for continued support. Following are some of the pros and cons when parents claim their adult children as dependents.

Pros

The pros of claiming a dependent generally accrue to the taxpayer claiming the deduction—in this case, your parents. Although the tax exemption for dependents went away in 2018, there are still potential benefits to claiming an adult child as a dependent. Here are a few examples:

Pros

  • Credit for other dependents: Your parent may qualify for the credit for other dependents, a $500 nonrefundable tax credit that applies for dependents ages 18 and older.

  • Filing head of household: A single parent with a qualifying dependent can file as head of household and claim a higher standard deduction.

  • Earned income tax credit: Additional dependents can help low- to moderate-income parents qualify for the earned income tax credit.

  • Educational expense tax credits: Parents who cover their children's college expenses may be entitled to up to $2,500 in tax credits under the American opportunity tax credit.

  • Deducting student loan interest: Parents may be able to deduct student loan interest if they've taken out student loans to pay for a dependent child's education.

  • Qualifying medical expenses: If your parents itemize, they may be able to include your qualifying medical expenses as part of their medical expense deduction.

Cons

The primary cons of being claimed as a dependent belong to the dependent (also known as you). The drawbacks here aren't necessarily major, but are worth considering:

Cons

  • You need to coordinate taxes with your parents. You should confirm with your parents that your income and residency don't disqualify you from being claimed as a dependent. Additionally, you and your parents should agree that you'll be claimed as a dependent so you can all file taxes accordingly.

  • You can't claim the same deductions and credits as your parents. For example, if your parents claim the American opportunity tax credit, you can't.

  • Your standard deduction may be affected. For dependents, the standard deduction—the amount of money you can exclude from your taxable income—is either $1,300 or your earned income plus $450, whichever is greater (not to exceed the basic standard deduction for your filing status).

Do Dependents Have to File Taxes?

As a dependent, you may need to file taxes if your income exceeds IRS thresholds. Single dependents under age 65 (who are not blind) must file tax returns when their incomes reach these levels:

  • Unearned income greater than $1,300
  • Earned income greater than $14,600
  • Gross income greater than the larger of:

    • $1,300, or
    • Earned income up to $14,150 plus $450

The Bottom Line

If you're financially dependent on your parents even after you turn 18, you may still qualify as a dependent on their tax returns. Claiming you as a dependent may save your parents money on their taxes, but it's important to stay up to date on tax policies and income limits related to claiming dependents as you go. IRS Publication 501 is updated yearly and contains all the details you need.
