3. (1) The method of determining the amount to be withheld shall be prescribed by regulations of the director of revenue. The prescribed table, percentages, or other method shall result, so far as practicable, in withholding from the employee’s wages during each calendar year an amount substantially equivalent to the tax reasonably estimated to be due from the employee under this chapter with respect to the amount of such wages included in his Missouri adjusted gross income during the calendar year.

(2) The amount to be withheld by an employer with respect to tips received by an employee in the course of the employee’s employment shall be calculated based solely upon the amount of tips reported by the employee in a written statement furnished to the employer as required by subsection (a) of Section 6053 of the Internal Revenue Code of 1986, as amended, or, if greater, the amount of tips received by the employer and remitted to the employee. If an employee shares tips, the employer shall withhold only from the employee who actually receives^* the shared tips. The employer’s Missouri income tax withholding obligation with respect to an employee’s tip income shall be limited to the portion of the employee’s wages under the control of the employer against which the employer is required, pursuant to federal law, to withhold federal income taxes on the employee’s tips. Such withholding obligation shall be calculated after making reductions for all required federal tax withholding, Missouri income tax withholding on nontip income, and other amounts which have higher legal priority.

4. For purposes of this section an employee shall be entitled to the same number of personal and dependency withholding exemptions as the number of exemptions to which he is entitled for federal income tax withholding purposes. An employer may rely upon the number of federal withholding exemptions claimed by the employee, except where the employee provides the employer with a form claiming a different number of withholding exemptions in this state.

5. The director of revenue may enter into agreements with the tax departments of other states (which require income tax to be withheld from the payment of wages) so as to govern the amounts to be withheld from the wages of residents of such states under this section. Such agreements may provide for recognition of anticipated tax credits in determining the amounts to be withheld and, under regulations prescribed by the director of revenue, may relieve employers in this state from withholding income tax on wages paid to nonresident employees. The agreements authorized by this subsection are subject to the condition that the tax department of such other states grant similar treatment to residents of this state.

6. The director of revenue shall enter into agreements with the Secretary of the Treasury of the United States or with the appropriate secretaries of the respective branches of the Armed Forces of the United States for the withholding, as required by subsections 1 and 2 of this section, of income taxes due the state of Missouri on wages or other payments for service in the Armed Services of the United States or on payments received as retirement or retainer pay of any member or former member of the Armed Forces entitled to such pay.

7. Subject to appropriations for the purpose of implementing this section, the director of revenue shall comply with provisions of the laws of the United States as amended and the regulations promulgated thereto in order that all residents of this state receiving monthly retirement income as a civil service annuitant from the federal government taxable by this state may have withheld monthly from any such moneys, whether pension, annuities or otherwise, an amount for payment of state income taxes as required by state law, but such withholding shall not be less than twenty-five dollars per quarter.

8. The provisions of this section shall not apply to out-of-state businesses operating under sections 190.270 to 190.285.
