You can request copies of your IRS tax returns from the most recent seven tax years. The Internal Revenue Service (IRS) can provide you with copies of your tax returns from the most recent seven tax years. You can request copies by preparing Form 4506 and attaching payment of $50 for each one. Once the IRS receives your request, it can take up to 60 days for the agency to process it.
You'll get your refund in as fast as 7 days when you e-file.*. *Update for 2014: The IRS issued more than 9 out of 10 refunds to taxpayers in less than 21 days last year. The same results are expected in 2014. Tax refunds are processed by the IRS two times per week. On the first day, the IRS only processes refunds that it will make through direct deposit, and on the second processing day, the IRS mails all refund checks to taxpayers who don't choose direct deposit. But this doesnât mean your refund will be processed immediately after filing your tax return.
