OPINION
Alvin Kanofsky, proceeding pro se, appeals United States Tax Court orders sustaining the IRS’s calculations of his income tax and additions to tax, disallowing deductible business and rental expenses, and denying his post-judgment motion to vacate or revise a decision under Tax Court Rule 162. We will affirm.
At issue is Kanofsky’s tax liability for the years 2006 and 2007, during which he failed to submit returns or pay taxes due. According to a stipulation filed in Tax Court, Kanofsky was employed during those years as a full-time physics professor at Lehigh University in Bethlehem, Pennsylvania. His income included a Lehigh salary, Social Security payments, dividends, capital gains, and Teachers Insurance and Annuity Association distributions. In his Lehigh W-4 Forms, Kanofsky claimed exemption from all federal tax withholding, and he did not pay estimated taxes. As a result, in 2010, the IRS mailed him deficiency notices, assessing tax due and penalties. Kanofsky timely challenged the assessments in the United States Tax Court.
At trial, Kanofsky argued (pro se) that he was entitled to deductions for, inter alia, business expenses. He described a period of hardship during which he “ran into a worldwide scam,” and was forced to clear materials out of a building he owned and ordinarily used for business purposes. Kanofsky attempted to introduce documents in support of his claims, but many were not admitted due to IRS objections.
In its opinion, the Tax Court framed the pertinent inquiry as “whether [Kanofsky] is liable for the income tax deficiencies as determined by [the IRS and] and whether [Kanofsky] is liable for the additions to tax under [Internal Revenue Code] sections 6651(a)(1) and (2) for [tax years] 2006-07 and under section 6654 for 2007.” The Tax Court held that Kanofsky did not meet his burden of proof to show that his income was not taxable, and that his “vague and imprecise” testimony did not allow the Court “to ascertain the nature, scope, and purpose of [claimed business] activities and to identify any expenses that [Kanofsky] paid in connection with the activities that could have been deductible.” With regard to the additions to tax, the Court deemed Kanofsky to have “conceded any issue” because he “did not assign error to [the IRS’s] determinations of the additions to tax.” Kanofsky timely moved *97to vacate under Rule 162, in a motion the Tax Court denied, and now seeks review from this Court.1
We have jurisdiction under 26 U.S.C. § 7482(a)(1). Kanofsky challenges the legal, factual, and evidentiary bases of the Tax Court’s decision, which we review de novo, for clear error, and for abuse of discretion, respectively. See Crispin v. Comm’r, No. 12-2275, 708 F.3d 507, 513-14, 515-16 (3d Cir.2013).
Taxpayers bear the burden of establishing that they are entitled to deductions they claim, a burden that may be met through the production of records that the Internal Revenue Code requires to be kept.2 See 26 U.S.C. § 6001; INDOPCO, Inc. v. Comm’r, 503 U.S. 79, 84, 112 S.Ct. 1039, 117 L.Ed.2d 226 (1992). One such category of deduction is for “all the ordinary and necessary expenses paid or incurred during the taxable year in carrying on any trade or business.” 26 U.S.C. § 162(a).
Many of Kanofsky’s contentions on appeal revolve around a single theme: the Tax Court and the IRS treated him unfairly by “obstructing” his presentation of evidence, “suppressing” elements of his case, and otherwise threatening him. We have examined the entire transcript and simply cannot agree. The record reflects that Kanofsky was permitted to comb through the “stack” of documents he brought to the Tax Court and present argument about their relevance. Documents were excluded on relevance grounds that have a basis in the record. See Fed.R.Evid. 402; Whitehouse Hotel L.P. v. Comm’r, 615 F.3d 321, 330 (5th Cir.2010) (“Pursuant to Tax Court Rule 143(a), the Federal Rules of Evidence apply to trials in tax court.”). For example, Kanofsky sought to introduce a collection of duplicate paid receipts from property he owned near Lehigh University for the purpose of showing a “business expense.” See Tr. 36-38. But he was unable to show that he actually used that property for business purposes.3 See, *98 e.g., Tr. 39. On other occasions, the Court recognized the possible probative value of certain submissions and found them to be admissible. See, e.g., Tr. 55 (admitting 35-P and 36-P into evidence).
We have reviewed Kanofsky’s remaining arguments and find them to be unavailing. Nothing in his briefs, even liberally construed, see Weaver v. Wilcox, 650 F.2d 22, 26 (3d Cir.1981), suggests that the Tax Court erred in concluding that he failed to meet his burden of proof or did not owe the taxes or additions assigned. Because Kanofsky’s trial was not held before a special trial judge, Ballard v. Commissioner, 544 U.S. 40, 125 S.Ct. 1270, 161 L.Ed.2d 227 (2005), is irrelevant. Finally, his allegations of fraud and corruption, and his appeals to “whistleblower” status, do not appear to have any bearing on the present matter.4
For these reasons, Kanofsky has shown no error in the Tax Court’s rulings. We will affirm the judgment.
