I did my taxes for 2018 and my accountant forgot to add my $7500 tax credit for my 2018 Clarity purchase. The taxes I owed were $10,000 so he submitted an amended return and the IRS told me they cannot accept the amended return because I cannot go from "taxable to non taxable..." whatever that means. In other words....Once I submit a tax return that I owe money they cannot reduce the amount of what I owe even with an amended tax return. My response was WTF? Has anyone every heard of such a stupid thing? My accountant suggested a lawyer! I really hate the IRS!!
