The IRS Notice LT26 is most often used to request business tax returns after the IRS has previously sent correspondence to you. It is exactly the same as the Notice LT18 sent to Individuals.
Many times, taxpayers believe that they have filed. They can't believe the IRS says they didn't receive the return. This can be extremely aggravating but it is very difficult to prove you filed a return if the IRS says they did not receive it.
Respond to Notice LT26
Of course, because the return must be filed, it is easier to simply re-file than argue with the IRS. You may discover later that you can prove you filed the return. If so, there is a procedure to reverse the filing date on the IRS records & abate the penalties.
Nevertheless, because the IRS doesn't have the returns you have another opportunity to pour over your records & claim every deduction to which you are entitled!
