143.521. Declarations of estimated tax. — 1. Every resident and nonresident individual shall make a declaration of estimated tax for the taxable year, in such form as the director of revenue may prescribe if the Missouri estimated tax can reasonably be expected to be at least one hundred dollars. The director may increase the amount required for making a declaration of estimated tax to more than one hundred dollars or decrease such required amount, however, the decreased amount shall not be less than one hundred dollars.

2. Every corporation doing business in this state shall make a declaration of its estimated tax for the taxable year, in such form as the director of revenue may prescribe, if its Missouri estimated tax can reasonably be expected to be at least two hundred fifty dollars. The director may increase the amount required for making a declaration of estimated tax to more than two hundred fifty dollars or decrease such required amount, however, the decreased amount shall not be less than two hundred fifty dollars.

3. The term "Missouri estimated tax" means the amount which the taxpayer estimates to be the income tax under sections 143.011 to 143.996 for the taxable year less the amount which the taxpayer estimates to be the sum of any credits allowable, including tax withheld.

4. If they are eligible to file a joint declaration for federal tax purposes, a husband and wife may make a combined declaration of estimated tax as if they were one taxpayer, in which case the liability with respect to the estimated tax shall be joint and several. If a combined declaration is made, the estimated tax for such year may be treated as the estimated tax of either husband or wife, or may be divided between them, as they may elect on a combined return or on their separate returns.

5. An individual or corporation may amend a declaration under regulations prescribed by the director of revenue.

6. If on or before January thirty-first (on or before March first in the case of a farmer referred to in subsection 2 of section 143.531) of the succeeding taxable year an individual files a return for the taxable year for which the declaration is required, and pays in full the amount shown on the return as payable, such return:

(1) Shall be considered as his declaration if no declaration was required to be filed during the taxable year, but is otherwise required to be filed on or before January fifteenth; or

(2) Shall be considered as the amendment permitted by subsection 5 to be filed on or before January fifteenth if the tax shown on the return is greater than the estimated tax shown in a declaration previously made.

7. An individual or corporation having a taxable year of less than twelve months shall make a declaration in accordance with regulations of the director of revenue.

8. The declaration of estimated tax for an individual under a disability shall be made and filed in the manner provided in section 143.501 for an income tax return.
