Tax experts are fearful millions of Americans could miss out on receiving a stimulus check from the federal government meant to help stabilize the economy. 

According to CNN, people who don't file their tax returns are at risk of being overlooked by the government when checks are disbursed. Not filing your taxes or being enrolled in a government-funded program like social security could create a challenge for the IRS to track people down.

"These folks are very disconnected from the tax system. It's going to be very hard to get their payments out," said Elaine Maag, a research associate in the Urban-Brookings Tax Policy Center.

Working adults are not required to file their taxes if their annual income is less than $12,200. CNN reports low-income Americans are less likely to file their taxes due to the lack of incentives and credits.

People who have filed their taxes previously, however, should still have their information in the system to receive a check, but it could be delayed. 

Americans who receive financial assistance for a disability from the government and students who rely on federal loans as income may also be at risk of not receiving a stimulus check.

College students who are still listed as dependents on their parents' taxes will not receive a check despite several universities temporarily shutting their doors and forcing thousands of students to move out of their dorms. 

Parents with children over the age of 17 will also miss out on receiving an additional $500 even if they still lawfully claim them on their taxes.

CNBC reports young Americans will face unprecedented burdens due to the coronavirus' effects. As employees of service jobs, young adults, who make up almost half of the industry, are at risk of being laid off.

Maag believes a total of nearly 10 million people may be overlooked.

"This group is going to have to file, so it is key for the government to make it easy for them to do so and then to have very strong outreach to get the word out," said Chuck Marr, senior director of federal tax policy at the Center on Budget and Policy Priorities.

Incarcerated Americans are also included in the number of people who may miss out on federal assistance amid the coronavirus outbreak. 

The IRS has announced that people can still file their taxes ahead of the adjusted deadline to ensure they will be accounted for, however, CNN reports that Americans who are unfamiliar with the process may not receive the support they need. 

Additionally, some people may fear that filing their taxes in an effort to receive the stimulus check could cause them to be audited in the future for back taxes. The treasury will give people the option to register to receive their payment through a web portal if the IRS does not currently have their information on file.
