Iowa Admin. Code r. 701—302.20(422) — Adjustments to prior years

When Iowa requests for refunds are filed, they shall be allowed only if filed within three years after the tax payment upon which a refund or credit became due, or one year after the tax payment was made, whichever time is the later. Even though a refund may be barred by the statute of limitations, a loss shall be carried back and applied against income on a previous year to determine the correct amount of loss carryforward.
