Complete and sign Maryland Tax Form 502X, noting the needed changes. This form is similar in many respects to the original state tax form you filed, with some additional information requested. The tax form includes step-by-step instructions. You will want to have a copy of the original form(s) you filed for reference.

avoidance of interest for underpayment of estimated tax, obtain a Form 502UP for the tax year in question from any office of the Revenue Administration Division. Complete and attach it to your amended return. Enter any interest due on line 77 of Form 502X.
Attach a copy of your federal tax return, including any subsequent amendments.
Attach income statements, such as W-2s or 1099s, for any previously unclaimed income or withheld taxes.
