What Should I Do if I Agree with the Notice of Deficiency?
If you agree with the amendment the Internal Revenue Service has made and you don’t have any additional income, expenses, or credits that you should report, you won’t need to amend your tax return. Simply sign Form 5564, Notice of Deficiency – Waver and send it back to the government agency. If you agree but have additional income, expenses, or credits to claim, you’ll need to amend your original tax return with Form 1040-X.

If you realize the IRS is correct, pay off what you owe as quickly as possible, as it will start accruing interest. If you can’t afford to pay it all immediately, call the IRS notice of deficiency contact number you’ll find on the letter received, and work out a payment plan to avoid further penalties. 

What if I Disagree with the Statutory Notice of Deficiency?
If you think the IRS has received incorrect information or is mistaken, you can contact them with additional information and plead your case. You have 90 days from the date of the notice to dispute the claim by petitioning the Tax Court to reassess the liability proposed by your account’s examining agent. During this time, the IRS cannot assess or perform collections on your accounts.

You should provide the IRS with a written statement that explains the reason for your appeal. It’s wise to consider using the help of a  tax professional before appealing. If you’re incorrect, a tax expert will likely notice it before you appeal and save you time and money. if you’re correct, they can help you better prepare an appeal.

If your appeal proves to be unsuccessful, you’ll be required to pay the disputed amount and file a claim for a refund with the IRS. If they deny your claim, you may choose to file a lawsuit with the United States Court of Federal Claims or federal district court. You can also file a petition with the United States Tax Court to resolve the matter. Depending on where you file, the services of an attorney may be required.
