On May 17, 2006, President Bush signed into law the Tax Increase Prevention and Reconciliation Act of 2005. Many income tax benefits expired at the end of 2005 but were not extended by this legislation (e.g. the deduction for state and local sales taxes; the deductions for school teacher's expenses; the deduction for higher education expenses; etc.).
