OPINION *
Pro se appellant William Bullock appeals the District Court’s order denying his motion for a default judgment and granting the defendants’ motion to dismiss. For the reasons detailed below, we will affirm the District Court’s judgment.
Bullock instituted this action in 2012, filing a complaint that named the Internal Revenue Service (IRS) and four of its employees as defendants. The complaint presented standard tax-protestor claims, including the following: (1) domestically earned wages of U.S. citizens are not taxable because they are not listed in 26 U.S.C. § 861; (2) the Constitution does not permit a direct, non-apportioned income tax; (3) only residents of Washington, D.C., and other federal enclaves are subject to the federal tax laws; (4) the United’ States cannot tax the fruits of Bullock’s fundamental right to work; and (5) the United States must tax Bullock’s “gain”— the income he earns after subtracting the value of his labor — rather than his income.1 When the defendants did not file a responsive pleading within the prescribed period, Bullock filed a motion for a default judgment. The defendants then filed a motion to dismiss.
A Magistrate Judge recommended that the District Court, deny Bullock’s motion for a default judgment and grant the defendants’ motion to dismiss. More particularly, the Magistrate Judge concluded that Bullock had failed to state a claim as to the individual defendants, and that his claims against the United States were barred by sovereign immunity. The District Court approved and adopted this report and recommendation, and Bullock filed a timely notice of appeal to this Court.
*60We have jurisdiction pursuant to 28 U.S.C. § 1291. We review the District Court’s denial of Bullock’s motion for a default judgment for abuse of discretion, see Chamberlain v. Giampapa, 210 F.3d 154, 164 (3d Cir.2000), and exercise plenary review over the District Court’s order dismissing Bullock’s complaint, see Allah v. Seiverling, 229 F.3d 220, 223 (3d Cir.2000).
We agree with the District Court’s disposition of this case. As an initial matter, the Court did not abuse its discretion in denying Bullock’s request for a default judgment. In short, none of the relevant default-judgment factors militate in Bullock’s favor&emdash;he was not prejudiced by the defendants’ tardy filing, there is no indication that the defendants were culpable, and, as will be discussed below, the defendants had litigable defenses. See Chamberlain, 210 F.3d at 164. We therefore affirm the District Court’s denial of this motion.
Nor did the District Court err in granting the defendants’ motion to dismiss. As the Court explained, absent a waiver, sovereign immunity shields from suit the United States, FDIC v. Meyer, 510 U.S. 471, 475, 114 S.Ct. 996, 127 L.Ed.2d 308 (1994), its agencies, Beneficial Consumer Disc. Co. v. Poltonowicz, 47 F.3d 91, 94 (3d Cir.1995), and its employees sued in their official capacities, see Chinchello v. Fenton, 805 F.2d 126, 130, n. 4 (3d Cir.1986). Consent to suit “must be unequivocally expressed” in statutory text, and cannot simply be implied. White-Squire v. U.S. Postal Serv., 592 F.3d 453, 456 (3d Cir.2010) (quotation marks omitted).
In his complaint, Bullock identified two statutes in which Congress has waived the government’s sovereign immunity in tax matters. First, pursuant to 26 U.S.C. § 7433, a taxpayer may sue the United States to challenge the “collection of Federal tax.” Second, pursuant to 28 U.S.C. § 1346(a)(1), a taxpayer may sue the United States for the “recovery of any internal-revenue tax alleged to have been erroneously or illegally assessed or collected.”2 However, both of these statutes require a taxpayer to exhaust administrative remedies before bringing suit in federal court. See United States v. Dalm, 494 U.S. 596, 602, 110 S.Ct. 1361, 108 L.Ed.2d 548 (1990) (discussing exhaustion requirement for actions under § 1346(a)(1) (citing § 7422(a))); Venen v. United States, 38 F.3d 100, 103 (3d Cir.1994) (discussing exhaustion requirement for actions under § 7433 (citing 26 U.S.C. § 7433(d))). Bullock has acknowledged, in both the District Court and this Court, that he did not exhaust his administrative remedies. He contends that exhaustion would have been futile because he would have been denied relief, but that is not a legitimate excuse for failing to exhaust. See Bartley v. United States, 123 F.3d 466, 469 (7th Cir.1997) (explaining that “this kind of argument was long ago rejected by the Supreme Court”). Bullock’s failure to exhaust is fatal to his claims under § 7433 and § 1346(a)(1).3
*61Moreover, to the extent that Bullock sought to sue IRS employees in their individual capacities, his claims fare no better. We have squarely held that, given the existence of various statutes permitting taxpayer suits — including § 7433 and § 1346(a)(1) — “a Bivens [v. Six Unknown Federal Narcotics Agents, 403 U.S. 388, 91 S.Ct. 1999, 29 L.Ed.2d 619 (1971) ] action should not be inferred to permit suits against IRS agents accused of violating a taxpayer’s constitutional rights.” Shreiber v. Mastrogiovanni, 214 F.3d 148, 152 (3d Cir.2000). Bullock has identified no other statutory authority for his claims against the individual officials.
Finally, the District Court did not err in denying injunctive relief to Bullock. As the Court recognized, 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.” Bullock does not contest this ruling on appeal, and we therefore need not discuss it further. See Kost v. Kozakiewicz, 1 F.3d 176, 182 (3d Cir.1993).
Accordingly, we will affirm the District Court’s judgment.
