Your Guide to Standard Tax Deductions


The IRS is a living, breathing and very much a dynamic tax-collecting machine. Consequently, tax rules—especially deductions—change all of the time.

Staying on top of tax deductions can save you money.

That is why for 2009, MainStreet is bringing you the IRS deduction updates straight from the pages of the tax code. Here are four of the most straightforward—and most popular—tax deductions available to U.S. citizens:

  • 55 cents per mile for business,
  • 24 cents per mile for medical or moving purposes, and
