Mississippi Code Title 27. Taxation and Finance § 27-7-331

The commissioner shall prepare and furnish to employers state income tax withholding tables based on the current income tax laws of the state, taking into consideration the various deductions and personal exemptions allowed therein. Such tables shall be designed to provide for a yearly aggregate withholding that will approximate the state income tax liability of the average taxpayer, with the standard deductions and personal exemptions. The commissioner shall also make and prescribe such other rules, regulations and forms as he shall deem necessary or desirable for carrying out the purposes of this article. Any such tables promulgated by the commissioner shall not be designed to collect more than the amount of tax that the taxpayer can reasonably be expected to owe for the income year.
