Typical Length of Master's Degree Programs. A master's degree should take around two years to earn, during which time you'll complete between 30 and 50 hours of coursework and finish a written thesis that is likely based on original research of some kind. At the end of your program, you'll probably have to pass written or oral examinations as well.
The statute of limitations for additional tax debt is 3 years from the later of the due date or the file date of the tax return. If required tax was understated by more than 25%, the statute of limitations is 6 years.
The IRS Statute of Limitations allows you three years from the filing deadline to file your prior year return and claim your refund. For example, the last day to claim your tax refund for the 2013 tax year is April 15, 2017. This is because the deadline date was April 15, 2014. Keep in mind that they also have the same amount of time to audit you and up to ten years to collect any unpaid tax.
