PER CURIAM

      Timothy Sheridan claimed $1,000,000 as a loss due to theft or patent infringement

on his income tax returns for 2009, 2010, and 2011. Those returns were subsequently

audited by the Internal Revenue Service (“IRS”), which found that there had been no
judicial determination of patent infringement and damages and that Sheridan had not

established that any loss was actually sustained. It determined that he was not entitled to

the deductions and therefore served him with a notice of deficiency in the amount of

$43,167.

       Sheridan’s supposed losses apparently relate to his patent for a smokeless tobacco

pipe, U.S. Patent No. 7,415,982 (filed Feb. 15, 2001), which he claims has been infringed

upon by the people of the United States. He estimates that he has lost $20 billion dollars

as a result of that infringement, which he argues constitutes an “effective tax imposed.”

He filed a pro se complaint seeking to enjoin the Internal Revenue Service (“IRS”) from

auditing him further or collecting the taxes identified in his notice of deficiency, as well

as an order directing the agency to issue him a refund on behalf of the United States and

its people. The District Court dismissed the suit for lack of subject matter jurisdiction,

and Sheridan now appeals.1

       The Anti-Injunction Act, 26 U.S.C. § 7421(a), states that, with limited exceptions

not applicable here, “no suit for the purpose of restraining the assessment or collection of

any tax shall be maintained in any court by any person, whether or not such person is the

person against whom such tax was assessed.” Although the Act does not apply if it is

clear that under no circumstances could the Government ultimately prevail in its claim of

tax liability, Enochs v. Williams Packing & Navigation Co., 

, 7 (1962), the

Sheridan had no alternative remedy, see South Carolina v. Regan, 

, 378

(1984), but he could either petition the Tax Court pursuant to 26 U.S.C. § 6213 or, after

paying the assessed taxes, file a refund suit under 26 U.S.C. § 7422(a). Thus, the Act

applies in this case, and the District Court lacked subject matter jurisdiction to entertain

Sheridan’s claims regarding the tax deficiency identified in his 2009, 2010, and 2011

returns. Sheridan’s claim that his estimated $20 billion in losses constitutes a tax for

which he is owed a refund is nonsensical. Even if it were not, the District Court was

barred from entertaining this aspect of the suit under 26 U.S.C. § 7422(a) because

Sheridan did not first file a claim for this refund with the IRS.

       We will affirm the District Court’s dismissal of Sheridan’s suit.2

 We agree with the District Court’s determination that any amendment to this complaint
would have been futile. Cf. Grayson v. Mayview State Hosp., 

, 114 (3d Cir.
2002).
