(1) The tax levied by RCW
82.08.020 does not apply to the sale of conifer seed that is immediately placed into freezer storage operated by the seller and is: (a) Used for growing timber outside Washington; or (b) sold to an Indian tribe or member and is to be used for growing timber in Indian country. This section applies only if the buyer provides the seller with an exemption certificate in a form and manner prescribed by the department. The seller shall retain a copy of the certificate for the seller's files. For the purposes of this section, "Indian country" has the meaning given in RCW
82.24.010.
(2) If a buyer of conifer seed is normally engaged in growing timber both within and outside Washington and is not able to determine at the time of purchase whether the seed acquired, or the seedlings germinated from the seed acquired, will be used for growing timber within or outside Washington, the buyer may defer payment of the sales tax until it is determined that the seed, or seedlings germinated from the seed, will be planted for growing timber in Washington. A buyer that does not pay sales tax on the purchase of conifer seed and subsequently determines that the sale did not qualify for the tax exemption must remit to the department the amount of sales tax that would have been paid at the time of purchase.
(3) A buyer who pays retail sales tax on the purchase of conifer seed and subsequently determines that the sale qualifies for the tax exemption provided in this section is entitled to a deduction on the buyer's tax return equal to the cost to the buyer of the purchased seed. The deduction is allowed only if the buyer keeps and preserves records that show from whom the seed was purchased, the date of the purchase, the amount of the purchase, and the tax that was paid.
