The small intestine is a narrow tube and is about 6 metres long. Here the major food groups, protein fat and carbohydrate are broken down into amino acids, sugars and fatty acids, which are then absorbed into the blood stream. It can take between 2- 6 hours for a meal to be processed in the small intestine.
Contributions made on the part of the employer are due by the business' filing due date for the tax year - usually April 15, or Oct. 15 if there is an extension. However, there are Department of Labor rules governing SIMPLE IRA plans that are different from IRS requirements.
Contribution Limits. As of 2012, the IRS limits the amount of your contribution to a SIMPLE IRA to $11,500 a year. If you are age 50 or above, you are also allowed an additional catch-up contribution of $2,500. After you reach the minimum retirement age of 59 1/2, you may begin taking withdrawals; the IRS will levy tax on the account earnings.
