The 3 year extension is just to collect ALL assets and report to the IRS. I hope that they don't wait until then to pay us all at once, nor does the IRS allows them to wait 3 more years and not pay tax.
Question is that is this a double taxation, i.e. the Trust pays tax and when we get the money then we will pay tax again? I guess so, because it is the same as companies pay tax on their income and then we pay tax again on the stock gain or dividend if any.
