PER CURIAM

       Peter Polanco, proceeding pro se, appeals an order of the United States Tax Court

determining a tax deficiency and penalty owed to the Internal Revenue Service (“IRS”).




*
 This disposition is not an opinion of the full Court and pursuant to I.O.P. 5.7 does not
constitute binding precedent.
                                             1
For the reasons that follow, we will affirm the judgment of the Tax Court.

       Polanco filed a joint federal income tax return for the tax year 2013. It is

undisputed that Polanco did not report income he received in the amount of $149,062.

On June 22, 2015, the IRS issued a notice of deficiency to Polanco and his wife. The

notice set forth a deficiency of $28,864 and a penalty of $5,103. Polanco filed a petition

challenging the notice of deficiency. He stated that the IRS had already determined that

no action was necessary with respect to his account. The Tax Court held a trial and

Polanco asserted that letters he and his wife had received from the IRS dated March 13,

2015, September 26, 2016, and September 30, 2016, precluded the IRS from issuing the

notice of deficiency.

       The Tax Court upheld the deficiency and penalty. In an oral opinion, the Tax

Court explained that 26 U.S.C. § 7121 sets forth the exclusive means by which the IRS

and a taxpayer may enter into a final agreement regarding tax liability, and that IRS

regulations require such an agreement to be set forth on one of two forms. The Tax Court

ruled that the letters relied upon by Polanco did not constitute such an agreement. The

Tax Court also explained that, even if the letters were binding, it could not determine

what they mean because it did not have all of the correspondence between the IRS and

the Polancos. This appeal followed.

       We have jurisdiction pursuant to 26 U.S.C. § 7482(a)(1). We review the Tax

Court’s legal conclusions de novo and its factual findings for clear error. Anderson v.




                                             2
Comm’r of Internal Revenue, 

, 164 (3d Cir. 2012).

       Polanco reiterates on appeal that the three letters from the IRS preclude the notice

of tax deficiency. He asserts that the letters relate to the 2013 tax year and that the matter

should not have gone to trial. We agree with the Tax Court that it is not clear what the

letters mean. The March 13, 2015 letter thanked the Polancos for correspondence

received on December 29, 2014, and stated that the IRS had reviewed the information

provided and determined that no action was necessary on their account. The letter refers

to the tax period ending December 31, 2014. The September 26, 2016 letter is addressed

to Polanco’s wife and thanked her for her inquiry of July 22, 2016. The IRS stated that it

had sent her a letter in error thanking her for information she had sent and explaining that

it would contact her, and that it had resolved the issue on her account and did not need to

take any further action. The September 30, 2016 letter is also addressed to Polanco’s

wife. This letter also responded to her July 22, 2016 inquiry and is essentially the same

as the September 26, 2016 letter. The latter two letters refer to the tax period ending

December 31, 2013.

       Polanco did not provide the correspondence he and his wife sent to the IRS and

did not satisfy his burden of proving that the deficiency determination is incorrect. See

Duquesne Light Holdings, Inc. & Subsidiaries v. Comm’r of Internal Revenue, 

, 403 (3d Cir. 2017) (noting taxpayer’s burden of proof). Moreover, Polanco does not

challenge on appeal the Tax Court’s conclusion that the letters do not constitute

agreements entered into under 26 U.S.C. § 7121, which authorizes the Secretary of the

Treasury to enter into a written agreement regarding taxpayer liability. See Sunik v.

regarding taxpayer liability must be executed on forms prescribed by IRS).
