The Mississippi Adjustments And Contributions Form is a supporting tax schedule used with a Mississippi individual income tax return to report several types of adjustments, itemized deductions, interest and dividend calculations, voluntary refund contributions, rental and pass-through income details, and other supplemental income items. Instead of covering just one narrow topic, this form acts like a multi-part worksheet that gathers several categories of information that may need to flow to the main Mississippi return. Depending on your situation, you may use it to calculate Mississippi itemized deductions, separate taxable interest and dividends from nontaxable Mississippi amounts, report voluntary check-off contributions from your refund, list rental real estate or royalty income, include income or loss from partnerships, S corporations, estates, and trusts, and report other special income items such as net operating loss adjustments, first-time home buyer unqualified expenses, catastrophe savings taxable distributions, and other supplemental income or loss entries. Because the form serves several different purposes, many taxpayers will complete only some parts while leaving others blank. The key is to understand which sections apply to your return and to carry each completed amount to the correct line on the related Mississippi tax form. Careful entry is important because each part connects to a different area of the main return, and mistakes can affect deductions, income totals, refund amounts, or tax due.
How To File Mississippi Adjustments And Contributions Form
Complete only the parts of the form that apply to your tax situation, then attach the schedule to your Mississippi return. Make sure your taxpayer name and Social Security number match the information on the main return.
If you are itemizing for Mississippi, complete Part I. If you need to report interest and dividends, complete Part II. If you want to donate part of your refund, complete Part III and remember that this section is for residents only. If you have rental, royalty, partnership, S corporation, estate, trust, or other supplemental income items, complete Parts IV and V as needed.
Attach any required supporting schedules when the form calls for them. For example, itemized deduction entries and rental income details may require federal schedules or state K-1 information to support the figures entered.

Important Filing Tips
Complete only the sections that apply to your return, but review the entire form so you do not miss a line that affects your income or deductions. Some lines carry directly to the resident return, while others carry to the nonresident return, so be sure you are transferring each total to the correct form.
If a section calls for an attachment, include it with your return. Missing attachments can delay processing or cause the state to question the amount claimed.
Common Mistakes To Avoid
Do not mix taxable and nontaxable Mississippi amounts in the interest and dividend section. The whole point of Part II is to remove nontaxable Mississippi amounts before transferring the taxable figure to the return.
Also avoid skipping the total lines after entering component amounts. In this form, many lines are calculation lines that determine the amount that actually moves to the main return, so they are just as important as the entry lines above them.
