On Dec. 19, the president signed into law the Tax Increase Prevention Act of 2014 (TIPA), which extended through Dec. 31, 2014, many valuable tax breaks that had expired at the end of 2013. Here are three that individuals may be able to take advantage of when filing their 2014 returns:1. State and local sales tax deduction. Individuals can take an itemized deduction for state and local sales taxes instead of for state and local income taxes. This option can be valuable for taxpayers who live in states with no or low income tax rates or purchase major items, such as a car or boat.
