It's that time of year again when parents and college or college-bound students fill out the FAFSA (Free Application for Federal Student Aid).

The idea of wading through a form – especially one that requires financial information – is definitely not an appealing idea, but the FAFSA could be a tremendous help in getting your student money to attend college.

The following points are what you need to know, as well as common mistakes to avoid when filling out the FAFSA.

Fill it out – you have nothing to lose.

You may think that you don't need to fill out the FAFSA, especially if you believe you might not qualify for need-based aid. But there's no income cut-off point with federal student aid, according to the U.S. Department of Education. In addition, the FAFSA can help you qualify for all kinds of grants, loans and scholarships, including those offered by your state, school or private organizations.

By investing a few minutes of time, you could reap thousands of dollars in potential rewards.

Submit it ASAP.

The sooner you submit your FAFSA, the better, according to consumer adviser Clark Howard. Although the federal deadline isn't until June 30, 2018, you should check with the financial aid administrator at colleges you're interested in to make sure their deadlines aren't earlier.

Submitting earlier will help you plan how you'll pay for college. You'll also have a better chance of getting as much aid or scholarship money as possible since some colleges distribute their available money on a first-come, first-serve basis, Howard says.

Gather the information you'll need.

The FAFSA asks questions about the student as well as his or her parents if the student is a dependent.

You'll need the following information on hand as you fill out the FAFSA:

  • The student's Social Security number
  • The parents' Social Security numbers
  • Driver's license number (if you have one)
  • Alien registration number (if you're not a U.S. citizen)
  • Federal tax information for the student (and his or her spouse, if applicable) and the parents. This can often be imported online, so you may not need your records.
  • Information on the student's and parents' assets, such as money held in bank accounts and real estate holdings (not your primary residence)
  • Records of the student's or parents' untaxed income, such as veterans benefits and interest income

Watch out for common mistakes.

The National Association of Student Financial Aid Administrators points out some common mistakes that can delay your form's submission or cause you to not get the aid and scholarships you might qualify for. They include the following:

  • Leaving some fields blank – Instead, put in a "0" or "not applicable."
  • Listing an incorrect Social Security or driver's license number – It pays to recheck these numbers.
  • Failing to use your legal name – Use the name on your Social Security card, not a nickname.
  • Forgetting to list colleges – Even if you're not sure of which college you'll be attending, add any reasonable possibilities to the list of colleges that will receive your information. You're under no obligation to apply to or attend these colleges, and they can't see which other colleges you're interested in.

Keep an eye out for requests for more information.

Your FAFSA may be selected for verification, which means you'll have to provide some additional or supporting information, U.S. News & World Report explains. This process doesn't necessarily mean you've done anything wrong. You may have a discrepancy or mistake on your form, but some FAFSAs are just randomly selected for verification (lucky you!).

These requests will often come to the student's personal email account or university email address, so he or she will have to be diligent about checking it and responding to any requests by the stated deadline.
