Publication 17

Your Federal 
Income Tax

rule

For Individuals

All material in this publication may be reprinted freely. A citation to Your Federal Income Tax (2017) would be appropriate.
The explanations and examples in this publication reflect the interpretation by the Internal Revenue Service (IRS) of:
  • Tax laws enacted by Congress,
  • Treasury regulations, and
  • Court decisions.
However, the information given does not cover every situation and is not intended to replace the law or change its meaning.
This publication covers some subjects on which a court may have made a decision more favorable to taxpayers than the interpretation by the IRS. Until these differing interpretations are resolved by higher court decisions or in some other way, this publication will continue to present the interpretations by the IRS.
All taxpayers have important rights when working with the IRS. These rights are described in Your Rights as a Taxpayer in the back of this publication.

    1. The credit for nonbusiness energy property,
    2. Parts of the credit for residential energy property,
    3. The deduction for mortgage insurance premiums,
    4. 7.5% of adjusted gross income threshold for deducting medical and dental expenses,
    5. The credit for alternative fuel vehicle refueling property, and
    6. The deduction for tuition and fees.
