If your parents claim you as a dependent on their tax return, you cannot claim your personal exemption on your return. Health-insurance coverage and student-loan interest are among other considerations for many younger taxpayers.

Millennials are in a life phase of ongoing change and evolution — from students to graduates to independents to spouses. Navigating the in-betweens of these milestones is no cakewalk.

In addition to the standard financial commitments that accompany such milestones, millennials must remain mindful of how their ever-shifting circumstances influence their tax obligation.

Here are three common tax mistakes millennials should watch out for.

• No longer a dependent

When it comes time to file your taxes, it’s worth it to double-check with your parents before signing on the dotted line. If you still live at home or get any kind of financial assistance from your parents, be certain that you’ve elected the right filing status.

Parents can claim qualifying children under age 19 as dependents, or under age 24 if they are still students, according to the IRS. If your parents claim you as a dependent on their tax return, you cannot claim your personal exemption on your income tax return. Instead, check the box indicating that someone else can claim you as a dependent.

On the flip side, millennials might check this box and file as a dependent when they should instead file as independent, missing out on the opportunity to reduce their taxable income. The personal-exemption amount changes every year, but for tax year 2015, the amount is $4,000. That $4,000 personal exemption might be just the ticket some millennials need to finally get ahead financially.

• Passing on health insurance

People age 26 to 34 are the most uninsured of all age groups, with around 21 percent not having insurance, according to a recent Gallup-Healthways survey. Under the new health-care law, millennials who go without health insurance will have to pay a hefty penalty when they file their returns. Those who can afford health insurance but don’t buy it must pay what’s known as an individual shared responsibility payment, according to HealthCare.gov.

In 2015, the penalty is the higher of two alternatives: either 2 percent of your household income or $325 per adult and $162.50 per child under 18.

The only way around the non-coverage penalty is to qualify for an exemption by having a household income that’s less than 8.05 percent of the lowest-cost bronze level marketplace plan. If you find yourself stuck paying the non-coverage penalty, the IRS will hold back the amount of the fee from any future tax refunds. There are no liens, levies or criminal penalties for failing to pay the fee.

• Deducting student-loan interest

One of the ways the U.S. government supports higher education is by giving those with student loans a tax break based on how much interest they’ve paid over the course of the year. Unfortunately, millennials, the student-loan poster children, might forget to claim this deduction.

You might be able to deduct student-loan interest payments up to $2,500 on a qualified student loan, according to the IRS. Like most deductions and credits, there is an income limit to claim this deduction — your modified adjusted gross income can’t be over $80,000, or $160,000 if filing a joint return. Millennials should also know that they don’t have to file an itemized return to qualify for this deduction.
