Tax Amendments by States

Tax Amendment dates and forms by state are listed below. Tax amendments are generally due as soon as you discover an error on your accepted tax return. If you prepared and e-filed your federal and state returns on eFile.com and need to amend one or both of them, the federal can be amended from your eFile account. You may be able to print your state return as well and mail it as some state amendments only require you to check an amendment box rather than fill in an additional form. Contact us with questions on this. If you filed your income tax return on time and you do not owe taxes as a result of the tax amendment, generally you should not be subject to a late payment penalty.
