What Is the Maryland Definition of a Tax Amendment?
If you need to make changes in your original tax return for a specific year, then you must file a tax amendment form. You should file it no later than 3 years after the date of the original tax return. If the IRS makes changes to your tax return, you should notify the state of Maryland within a period of 90 days after the IRS made changes and finalized the process. Also, if you filed an amended federal tax return, you must also amend your Maryland state tax return.
