Failure to file the statements within the time prescribed therefor, unless shown to have been due to reasonable cause, or the willful filing or furnishing of false or fraudulent statements shall subject the employer to a penalty, at the discretion of the executive director, of not less than five dollars nor more than fifty dollars, which shall be in addition to any criminal penalty otherwise provided for failure to file a return or for filing a false or fraudulent return.

(7)
(a)
Every employer who deducts and withholds any amounts under the provisions of this section shall hold the same in trust for the state of Colorado for the payment thereof to the department in the manner and at the time provided for in this section, and the state of Colorado and the department shall have a lien to secure the payment of any amounts withheld and not remitted as provided in this section upon all of the assets of the employer and all property, including stock in trade, business fixtures, and equipment, owned or used by the employer in the conduct of his business, so long as any delinquency continues, which lien shall be prior to any lien of any kind whatsoever, including existing liens for taxes.
(b)
The owner, conditional vendor, or mortgagee of any property, real or personal, or any stock in trade, business fixtures, or equipment owned or used by an employer subject to the lien provided by this subsection (7), may exempt such property from the lien granted in this section to the state of Colorado and the department by requiring the employer to procure a certificate from the department certifying that such employer has posted with the department security for the payment of the amounts withheld under the provisions of this section. When such certificate is procured by the employer and transmitted to the owner, conditional vendor, or mortgagee of any of the assets of the employer, such assets shall thereafter be exempt from attachment under the lien granted to the state of Colorado and the department by this subsection (7).
(c)
Any employer shall provide a copy of any lease with an owner to the department of revenue within ten days of seizure of the property and assets described in paragraph (a) of this subsection (7). The department shall verify that such lease is bona fide and notify the owner that such lease has been received by the department. The department shall use its best efforts to notify the owner of the real or personal property which might be subject to the lien created in paragraph (a) of this subsection (7). The real or personal property of an owner who has made a bona fide lease to an employer shall be exempt from the lien created in paragraph (a) of this subsection (7) if such property can reasonably be identified from the lease description or if the lessee is given an option to purchase in such lease and has not exercised such option to become the owner of the property leased. This exemption shall be effective from the date of the execution of the lease. Such exemption shall also apply if the lease is recorded with the county clerk and recorder of the county where the property is located or based or a memorandum of the lease is filed with the department of revenue on such forms as may be prescribed by said department after the execution of the lease at a cost for such filing of two dollars and fifty cents per document. Motor vehicles which are properly registered in this state, showing the lessor as owner thereof, shall be exempt from the lien created in paragraph (a) of this subsection (7); except that said lien shall apply to the extent that the lessee has an earned reserve, allowance for depreciation not to exceed fair market value, or similar interest which is or may be credited to the lessee. Where the lessor and lessee are blood relatives or relatives by law or have twenty-five percent or more common ownership, a lease between such lessee and such lessor shall not be considered as bona fide for purposes of this section.
(c.5)
Any coin-operated vending machine or video or other game machine shall be exempt from the lien created in paragraph (a) of this subsection (7) if:
(I)
The machine is placed on the premises of an employer under the terms of a lease or other agreement under which the employer is given no right to become the owner of the machine;
(II)
The machine is plainly marked in a location accessible to agents of the department of revenue with information sufficient to permit identification of the owner of said machine; and
(III)
The owner of the machine has filed with the executive director a schedule listing the machine by serial number and including thereon the owner's full name and the address of his business and such other information as the executive director may require. To protect the anonymity of owners of property, the executive director may permit property covered by this paragraph (c.5) to be marked using numbers or other coded identification.
(d)
Any employer who is in possession of property under the terms of a lease, which property is exempt from lien as provided in paragraph (c) of this subsection (7), may be required by the executive director to remit tax funds collected at more frequent intervals than would otherwise be required, but no more frequently than the employer's payroll period, or may be required to furnish security for the proper payment of taxes whenever the collection of taxes appears to be in jeopardy.
(8)
The entire amount of income from wages upon which tax was deducted and withheld shall be included in the gross income of the income tax return required to be made by the employee, the recipient of the wages, without exclusion of such amounts deducted and withheld under this section, and any tax so deducted and withheld shall be credited against the total income tax, as computed in the employee's return, made in accordance with the provisions of this section.
(9)
Repealed.
(10)
In the event the excess tax deducted and withheld is one dollar or less, no refund shall be made, unless a specific claim for refund is filed by the taxpayer at the time the return is filed. The excess, subject to being refunded, shall in no event and under no condition be allowed as a credit against any tax accruing on a return filed for a year subsequent to the year during which the wages were received, and can only be credited against a tax accruing upon a return of wages from which such excess was deducted and withheld.
(11)
Separate refunds may be made by the department to two taxpayers who have filed a joint return, at the written request of either, the amount payable to each taxpayer being proportioned upon the gross earnings of each as shall be established to the satisfaction of the department. If an employee entitled to a refund dies, payment of such refund shall be made in such manner as provided for by law for distribution of moneys payable by the state of Colorado to a decedent.
(12)
(a)
(I)
Moneys remitted by employers under this section shall be deposited with the state treasurer and by him or her credited to a fund hereby established, denominated the "income tax withholding fund". Refunds as provided for by this section shall be made from this fund in the same manner as refunds are made under section
39-21-108
. Except for moneys to be transferred to the state treasurer pursuant to section
39-21-108 (5)
, all unexpended balances on hand in said fund on June 30, 1971, and each June 30 thereafter, or at any time as shall be determined by the controller, with the approval of the state treasurer, shall be credited to the general fund of the state. The unexpended balance shall include all moneys that for any reason cannot be refunded. All warrants that cannot be delivered to the taxpayer and that are not presented for payment within six months from the date of issuance thereof shall be void, and the moneys represented thereby shall be included in the unexpended balance in said fund at the expiration of said year. Except as provided in subparagraph (II) of this paragraph (a), persons entitled to the refund of moneys represented by warrants that cannot be delivered to the taxpayer and that are not presented for payment within six months from the date of issuance thereof may file claims for refund at any time within four years from the date the income tax return that establishes the right to the refund was required to be filed. Claims for refund not filed within the prescribed four-year period shall not be allowed or paid by the department of revenue.
(II)
On and after October 1, 2002, if the department of revenue has canceled a warrant pursuant to section
39-21-108
that has not been presented and has forwarded to the state treasurer information and an amount of money equal to the amount of the warrant as required by section
39-21-108 (5)
, the taxpayer must file the claim for the amount of the refund with the state treasurer pursuant to the "Revised Uniform Unclaimed Property Act", article
13
of title
38
. The department and the state treasurer shall cooperate to ensure that any taxpayer who contacts the department to claim the amount of a refund represented by a canceled warrant is provided with the information or assistance necessary to obtain the refund from the state treasurer.
(b)
All of the additional interest derived from moneys deposited in the income tax withholding fund created in paragraph (a) of this subsection (12) as a result of the enactment of House Bill 91S2-1027 at the second extraordinary session of the fifty-eighth general assembly shall be credited to the general fund.
(13)
The department is empowered to make rules and regulations for the enforcement of the provisions of this section, including rules and regulations for determining the amount, up to but not exceeding the amount limited in this section, to be deducted and withheld by employers from wages of nonresident employees, only a part of whose wages are paid for services performed within the state of Colorado.
(14)
Nothing in this section shall be construed to prevent any employee, with consent of his employer, from voluntarily subjecting himself to the provisions of this section, and in all such cases, same will be handled by the department of revenue in the same manner as those subjected by the provisions of this section.
(15)
Repealed.
(16)
(a)
On or before the date of the commencement of employment with an employer, the employee shall furnish the employer with a signed withholding certificate.

Where necessary to cause the proper amount to be withheld, the executive director may adjust the employee's withholding to the amount properly allowable under the internal revenue code.
(b)
(I)
To enforce the provisions of this section, the executive director may file with the employer a withholding certificate on behalf of the employee. Prior to the filing of such certificate, the executive director shall first notify the employee that the certificate previously filed by the employee is being examined and that the employee may submit satisfactory evidence pursuant to the internal revenue code within ten days of receipt of said notice as to the correct number of withholding exemptions and allowances. Should the executive director, after reviewing any evidence so submitted, find the certificate filed by the employee to be defective, the employer shall accept the certificate filed by the director in lieu of any certificate previously filed by the employee, and such certificate filed by the executive director shall thereafter form the basis for withholding wages as required by this section. The executive director may also require from the employer a copy of any withholding certificate signed by the employee.
(II)
Any employer who fails to provide a copy of any withholding certificate signed by the employee required by the executive director shall be subject to a civil penalty of not more than five hundred dollars. Such civil penalty may be assessed and collected by the executive director.
(c)
Any employee may request a hearing to protest such certificate filed on his behalf by the executive director. Such hearing shall be conducted pursuant to section
