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.
1. Check the limitations. When you find that you need to amend a tax return, you need to make sure the statute of limitations on filing one hasn't run out. The statute of limitations, or time allowed for the action, on getting a refund from an amended tax return is three years. That means if you're filing an amended tax return because you're hoping to get an additional refund, the cutoff time is three years after the original return was filed.
