CO SB279

Allows taxpayers appealing state or local tax determinations to voluntarily post a surety bond, make a deposit, or pay the disputed amount to the Department of Revenue before a district court ruling, without being required to do so.

Changes the requirement to post surety or make payment from within 15 days after filing a notice of appeal to within 14 days after receiving a district court ruling that is adverse to the taxpayer in part or in whole.

If a taxpayer chooses to deposit the disputed amount with the executive director, interest accrual stops during the pendency of the action and funds are returned with interest or applied against the deficiency based on final court direction.

Applies the same surety posting and payment timing requirements to local government sales and use tax appeals, requiring such payments only after an adverse district court ruling.

Applies to appeals filed on or after the effective date of the act.
