Lenticular Clouds (lens shaped clouds) can form in the crest of the mountain waves if the air is moist. Roll Clouds can also occur in the rotors below the waves if the air is moist. These clouds are a good indication of the presence of mountain waves but, if the air is dry, there may not be any cloud to see.
Statute of Limitations. The statute of limitations for taxpayers to receive refunds is three years from the date the return was filed or two years from the date any tax was paid for the tax year in question. This doesn&amp;rsquo;t preclude you from filing a return.
How many years back can you get a tax refund? 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.
