(c) For wage credits for future years, one-tenth of the credits shall be disallowed for each year the required level of employment was not maintained or the wage requirement was not met in previous years.
(3) Any amounts required to be recaptured shall be deemed to be an underpayment of tax, immediately due and payable, and shall constitute a lien on the assets of the taxpayer. When wage credits were received in more than one year, the credits received in the most recent year shall be recovered first and then the credits received in earlier years shall be recovered up to the extent of the required recapture.
(4) Interest shall accrue from the due date for the return for the year in which the taxpayer failed to maintain the required level of employment or meet the required wage level.
(5) Penalties shall not accrue until ninety days after the requirement for recapture or disallowance becomes known or should have become known to the taxpayer.
(6) The recapture or disallowance required by this section may be waived by the Tax Commissioner if he or she finds the failure to maintain the required level of employment or meet the required wage level was caused by unavoidable circumstances such as an act of God or a national emergency.
