Can I split the amount that is shown in my 1098-T form between my parent's tax return and mine? They helped me with half of my school tuition.

Unfortunately , the information on a 1098-T can not be split between 2 returns. 

If your parents are claiming you on their return then they would be allowed to enter the 1098-T on their return otherwise if they are not claiming you and you are going file a tax return then you would be allowed to claim the information on the 1098-T.

See below IRS requirements for education credit.

Qualifications for claiming the American Opportunity Tax Credit are:

• You paid qualified education expenses for higher education (see Related Information below)
• You paid education expenses for eligible students
• The eligible student is you, your spouse, or a dependent for whom you claim an exemption
• Your modified adjusted gross income is $90,000 ($180,000 if married filing jointly) or less (The credit is reduced between $80,000 and $90,000 ($160,000 and $180,000)
• You must be taking courses at an eligible education institution, which is any college, university, or vocational school with a student aid program administered by the US Department of Education.

You must be considered an eligible student:

• You are enrolled at least half-time in a program leading to a degree,certificate, or other recognized credential
• You had at least one academic period beginning during the year
• You did not use the American Opportunity Tax Credit in any four previous years
• You did not complete the first four years of post-secondary education before the beginning of the year

You are not eligible to claim the American Opportunity Tax Credit if:

• Your filing status is Married Filing Separately.
• Taxpayer is listed as a dependent on another person’s return.
• You and your spouse were non-resident aliens.
• You have a felony drug conviction.

You are eligible to claim the Lifetime Learning Credit if all of the following requirements are met:

• You (or your dependent or a third party) paid qualified education expenses for higher education.
• You paid the education expenses for an eligible student.
• The eligible student is you, your spouse, or a dependent you claim an exemption for on your tax return.
• Your modified adjusted gross income is less than $65,000($131,000 if you are married filing jointly).
• The credit is reduced between $55,000 and $65,000 ($111,000 and $131,000).

One of the advantages of the Lifetime Learning Credit is that you can take the credit every year for higher education as long as you meet the qualifying requirements.

That answered my question! Thanks a lot!
