(MoneyWatch) This is the time of year when millions of parents and students are grappling with 
financial aid forms. It's also the time of year when many families make 
financial aid mistakes.
Here are eight mistakes to avoid when completing the 
Free Application for Federal Student Aid (FAFSA), which families must fill out to be eligible to get financial assistance at thousands of schools, and the 
CSS/Financial Aid PROFILE, which approximately 20 percent of private institutions use.
1. Procrastinating. There
 is no federal deadline to submit the FAFSA, but state financial aid 
programs and colleges do impose aid deadlines. Check with schools on 
your child's list to see what their deadlines are, as well as your state
 aid program. You can find a link to every state's financial aid 
programs at the website of the 
National Association of Student Financial Aid Administrators. 
A
 growing number of states offer aid on a first-come, first-served basis.
 It's OK if you have to submit your aid application with estimated tax 
information. You can use the 
IRS data retrieval tool to update the FAFSA after you've completed your taxes. 
   
2. Failing to check for errors. When a parent or student makes mistakes on a 
financial aid form, it's highly likely that the household won't generate the right "
expected family contribution."
 The information that a family shares on the FAFSA and the PROFILE 
calculates their EFC, which is a dollar figure that represents the 
minimum amount that a family can expect to pay for one year of school.
  
 This might seem like a no-brainer, but parents don't always bother to correct 
FAFSA mistakes
 even when it can hurt them financially. Last year, more than 750,000 
students notified about FAFSA errors by the U.S. Department of Education
 failed to revise their aid applications, which potentially cost them 
money.
   
 
3. Including retirement assets. Don't include retirement assets on your 
FAFSA.
 I wish the aid application was clearer on this point. The FAFSA only 
wants you to divulge your non-retirement assets. If you include your IRA
 or 401(k) assets on the FAFSA, it could squash your chances for 
need-based aid.
 
   
  4. Providing the wrong tax figures. Parents
 should list the federal income tax that they paid or will pay based on 
their 2012 federal tax return -- not the tax withholdings on their W-2 
forms. The advice is the same for the students themselves.
  
5. Avoid blank answers. If
 the answer to a question is zero or not applicable, write "0" or "Not 
Applicable" on the online form. Leaving blank answers can cause 
miscalculations.
 
6. Don't inflate your education. Some 
institutions will award applicants brownie points if they are 
first-generation college students. If parents didn't graduate from 
college, select "high school" as the highest education attainment.
  
7. Failing to seek help. If
 you are overwhelmed by the process, seek help. You'll learn where you 
can turn for assistance by clicking on my recent post on 
FAFSA resources.
   
8. Failing to appeal a financial aid award. Schools
 don't broadcast this fact, but it is possible to successfully appeal 
disappointing financial aid awards. If the aid package your child 
receives is underwhelming, you can ask a college to reconsider the 
award. Just don't approach the school and announce that you want to 
"negotiate." Be diplomatic.
