Okla. Stat. tit. 68, § 68-224: Declaration of termination of taxable period and

acceleration of assessment.

(a) If the Tax Commission, notwithstanding that a tax return or

report, or the tax with respect thereto, may not yet be due, and

whether prior to or after the close of the taxable period, believes

that:

(1) The tax liability of any person, who has a bond on file with

the Tax Commission to indemnify the state for the payment of any

state tax, has accrued in excess of the amount of the bond, or

(2) A taxpayer intends to depart or remove from the state, or

conceal himself or any of his property subject to a lien for the

payment of any state tax, or

(3) A taxpayer intends to discontinue business, or

(4) A taxpayer intends to do any other act tending to prejudice

or render wholly or partially ineffectual proceedings to compute,

assess or collect any state tax, the Tax Commission shall by its

order declare the taxable period of any State tax terminated for

such person, and shall immediately assess the tax from any

information in its possession, notify the taxpayer, and demand

immediate payment thereof. In the event of any failure or refusal

to pay the tax by the taxpayer upon the demand of the Tax

Commission, the tax shall become delinquent and the Tax Commission

shall proceed to collect the same as in other cases of delinquent

tax.

(b) The order of the Tax Commission assessing the tax may be

appealed from as provided in this article, or the taxpayer may

furnish to the Tax Commission security that he will make any return

or report thereafter required to be filed with the Tax Commission,

and pay the tax with respect to the taxable period when due, as

provided for by the general procedure pertaining to the tax

involved. After security is approved and accepted, and such further

and other security with respect to the tax or taxes covered thereby

is given, as the Tax Commission shall, from time to time find

necessary and require, the payment of such taxes shall not be

enforced by any proceedings prior to the expiration of the time

otherwise allowed for paying such taxes.

(c) In cases where the assessment here authorized is made prior

to the close of the taxable period, and in case the taxpayer elects

to pay his taxes rather than to file a bond as herein provided for,

the taxpayer may pay to the Tax Commission the sum assessed,

together with additions to the tax provided by law, and at the time

of making such payment shall notify the Tax Commission of his

intention, at the close of the taxable period to file suit for

recovery as provided in this article. Upon receipt of such notice

the amount paid shall be segregated and held until the termination

of thirty (30) days following the close of the taxable period for

which levied; and if within such period, namely within thirty (30)

days following the close of the taxable period, taxpayer files suit

for recovery, the fund so segregated shall be further held pending

the final determination of such suit.
