Answers to common questions

How do I know if my business remains liable for excise taxes?

Your business is liable for excise tax if it involves goods, services, or activities identified on Form 720.

If I no longer owe excise taxes where to I mail my final Form 720?

File a final Form 720 if you no longer owe excise taxes because you’re either going out of business or you will not owe excise taxes in future quarters. Check the final return box above Part I of Form 720 and mail to IRS, Cincinnati, OH 45999-0009.

I don’t handle excise taxes for my corporation. How can I request that the IRS send all future notices directly to our accountant?
