Overview
If you did not pay enough in estimated tax payments or withholding throughout the year, Missouri may assess an underpayment penalty. To calculate and report this, you must complete Form MO-2210 – Underpayment of Estimated Tax, which is submitted with your MO-1040 return.
When Should You File Form MO-2210?
You may need to complete MO-2210 if:
- You owe $500 or more on your Missouri return after subtracting withholding and credits.
- You paid less than 90% of your current-year tax liability through estimated payments or withholding.
- Your estimated tax payments were late or uneven, and you want to use the annualized income installment method or claim an exception to reduce or eliminate the penalty.
Note: Even if you are not required to file Form MO-2210, doing so may help reduce or waive penalties if you qualify for a special exception.
