Sorry for posting in here as there doesn’t seem to be a “general” forum spot yet.
A taxpayer reached out to me about correcting their annual return as they had included leased equipment in error for the last two years. They are now asking for the previous years to be corrected but I informed them they are past the appeal deadline.
Am I required to make these abatements if they show proof they were also billed the tax by the leasing company for this equipment, or just amend the return going forward? To my knowledge, the form is self-reported and no adjustments can be made past the standard appeals deadline. I just want to know that this is standard practice.
