Llewellyn Greene-Thapedi brought this action in the United States District Court for the Northern District of Illinois. She sought a refund of an overpayment of income tax that she had paid for the 1999 *531 taxable year, but which the IRS had applied to taxes that she owed from the 1992 taxable year. The district court determined that the Government properly assessed the taxes, notified Ms. Greene-Thapedi of the 1992 tax deficiency and issued Ms. Greene-Thapedi a refund check for the remaining amount she was owed. It therefore entered judgment in favor of the Government. We vacate the judgment of the district court and remand the case with instructions that the district court dismiss the case for lack of subject matter jurisdiction.

BACKGROUND
A.
On April 30, 1996, Ms. Greene-Thapedi filed a tax return for 1992 and reported a liability of $31,342, which was $1,342 more than the estimated tax payment she had previously made. The IRS challenged her reported liability. It determined that she owed an additional $24,966 plus penalties and sent Ms. Greene-Thapedi a notice of deficiency on August 29,1996.
Ms. Greene-Thapedi filed a petition in the United States Tax Court for a redeter-mination of the taxes that she owed for the 1992 taxable year. On June 5, 1997, the tax court determined that she owed the Government $10,195.
On December 19,1997, the IRS assessed the $10,195 deficiency, plus $4,319.53 in interest against Ms. Greene-Thapedi. The IRS claims that it sent her a notice of deficiency that day. Ms. Greene-Thapedi, however, maintains that she did not receive the notice.
On July 3, 2000, the IRS sent Ms. Greene-Thapedi a notice of intent to levy assets. The notice stated that she owed $23,805.53 in taxes, interest and penalties for the 1992 taxable year. Ms. Greene-Thapedi paid $10,195 for the deficiency and $4,319.53 for the interest accrued through December 19, 1997, but refused to pay any interest and penalties from December 19, 1997 to July 3, 2000 on the ground that she had not received the December 1997 deficiency notice.
B.
Ms. Greene-Thapedi also brought an action in the tax court to recover a $10,663 overpayment of her 1999 federal income tax. In October 2002, while this action was pending, the IRS applied the 1999 overpayment to her disputed 1992 tax liability. See I.R.C. § 6402(a). This offset not only eliminated Ms. Greene-Thapedi’s 1992 liability, but also left a credit on her 1992 account.
In 2003, Ms. Greene-Thapedi filed this action in district court to recover the 1999 overpayment. The district court stayed its proceedings pending the outcome of the tax court proceeding. In January 2006, the tax court held that because of the offset, it no longer had jurisdiction over the suit, and it concluded that her claim was moot. The tax court held that, because the application of the 1999 funds extinguished any remaining liability for 1992, no further collection action could take place. The tax court also held that it lacked jurisdiction either to determine if the funds credited to her 1992 liability constituted an overpayment or to order a refund.
The Government consequently filed a motion to dismiss the district court action. Because the 1999 overpayment offset liability for 1992, the Government submitted, Ms. Greene-Thapedi no longer had a claim for a refund from the 1999 taxable year. It furthermore maintained that Ms. Greene-Thapedi could not sue for a refund for the overpayment until she exhausted *532 her administrative remedies by filing a refund claim with the IRS. The district court denied the motion; it held that her tax court petition constituted an informal claim for a refund.
Ms. Greene-Thapedi filed a second amended complaint seeking a refund of $10,663, plus interest for the tax year 1992. The district court held that the IRS properly calculated the overpayment credit due to Ms. Greene-Thapedi, $3,772.16, based on the 1992 liability and the 1999 overpayment. In arriving at this figure, the district court found that Ms. Greene-Thapedi did not present sufficient evidence to rebut receipt of the December 1997 deficiency notice, and thus she owed the IRS interest from 1997 to 2000.
The Government subsequently issued a check to Ms. Greene-Thapedi for her overpayment, which she cashed. Consequently, on February 14, 2008, the district court found that no genuine issue of material fact remained and entered judgment for the Government. Ms. Greene-Thapedi now appeals.
II
DISCUSSION
Ms. Greene-Thapedi submits that the district court erred in dismissing the case. She contends that a reasonable fact-finder could determine that she did not receive the December 1997 deficiency notice for the 1992 taxable year, that the Government’s calculations of interest and penalties were incorrect and that these factual issues warranted further litigation in the district court.
We cannot address the merits of Ms. Greene-Thapedi’s arguments because the district court lacked subject matter jurisdiction to hear this case. Under section 7422(a) of the Internal Revenue Code, a district court lacks jurisdiction over a refund claim that has not first been filed with the IRS.
United States v. Dalm,
The district court held that Ms. Greene-Thapedi’s informal claim conferred it with subject matter jurisdiction. However, her subsequent failure to file a formal claim barred the court from exercising any jurisdiction over the claim.
See United States v. Kales,
Conclusion
The district court lacked jurisdiction to hear Ms. Greene-Thapedi’s action seeking a refund from her 1992 tax liability. We therefore vacate the district court’s judgment and remand the case to the district court with instructions to dismiss the case.
Vacated and Remanded with Instructions.
