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.
You Have Three Years to Claim a Tax Refund. This statute is a big tricky. You have three years from the date of the original deadline of the tax return to claim your refund or two years from the date the tax was actually paid, whichever is later. For example, your 2016 tax return is due on April 18, 2017. If you add three years to this filing deadline, you have until April 18, 2020 to file your 2016 tax return and still get a tax refund. It goes away forever because the statute of limitations for claiming a refund has closed.
