Tax filing is a requirement for all American citizens who have a source of income. It can be a serious headache for those who are not knowledgeable about what is deductible and what can not be deducted on their federal income tax return. There are numerous deductible items you can take on your tax return to reduce your tax liability. These deductible items are usually filed on schedule A form 1040. Before you file your 2011 tax return find out if you may reduce your tax liability by taking qualified Federal Income Tax Deductions. It will be a good practice if you keep good records and you understand what deductions to declare and save money during tax time.
