SUHRHEINRICH, Circuit Judge.
Petitioner appeals from the tax court’s order denying his motion to vacate a default judgment granting the deficiency amount and fraud penalties. For the reasons stated below, the decision of the tax court is AFFIRMED.
I.
On April 15, 1976, the Commissioner of Internal Revenue (“Commissioner” or “respondent”) sent a statutory notice of deficiency to petitioner, Donald G. Smith (“petitioner”), seeking deficiency taxes and fraud penalties based on alleged unreported income for the tax years 1972 and 1973. Petitioner filed a request for redetermination with the tax court on June 17, 1976. At the time he filed his petition, petitioner was incarcerated in the Federal Penitentiary in Lewisburg, Pennsylvania. As his reason for disagreement with the notice of deficiency the petitioner stated that: “I am at Lewisburg penitentiary and am presently sueing [sic] the I.R.S. in Cleveland, Ohio concerning this investigation. I state my taxes are correct to my knowledge. I am requesting appointed counsel.” Petitioner did not allege any specific facts in support of his contention. Prior to incarceration, petitioner had resided in Ohio.
The Commissioner filed an answer denying the substantive allegations of the petition and further alleging that part of the underpayments of tax required to be shown on petitioner’s income tax return for the years in question were due to fraud. In support of the fraud allegation, the answer to the petition listed taxable income derived from various sources in the taxable years 1972 and 1973, including receipts from narcotics trafficking, wagering, odd jobs, real property, and wages and unemployment compensation. The Commissioner’s answer also set forth in detail the facts upon which he based his analysis of petitioner’s net worth, including petitioner’s beginning cash on hand, specific assets acquired and liabilities incurred by petitioner during the relevant taxable years, specific expenditures by petitioner for personal living expenses during the years in issue, and specific nontaxable receipts of petitioner during the years in question. The Commissioner determined an increase in petitioner’s net worth for taxable year 1972 in the amount of $13,181.87 and an increase in petitioner’s net worth for taxable year 1973 in the amount of $19,782.48.
Petitioner thereafter filed a reply entitled “Rebuttal to Respondent’s Answer,” which only generally disputed the allegations contained in the Commissioner’s answer. The petitioner also filed a “Response to Respondent’s First Request for Admissions” on April 13, 1978, even though the Commissioner did not file with the Court any request for admissions.1 That document also [1473]*1473only generally disputed the allegations in the Commissioner’s answer. On July 1, 1977, the Commissioner filed a motion to transfer the place of trial from Philadelphia to Cleveland, which the petitioner opposed. That motion was denied at a hearing conducted on August 14, 1977. On March 5, 1981, petitioner’s address was changed on all the court records to reflect his transfer to the Federal Correctional Institute, Oxford, Wisconsin.
No further action was taken until June 2, 1987, when a Notice of Trial and Pretrial Order was mailed to petitioner setting the case for trial in Philadelphia, Pennsylvania on November 2, 1987 at 10 a.m. The notice also advised the parties that failure to appear at the time and/or failure to cooperate in the preparation of an agreement on all facts and documents as to which there should be no disagreement might result in dismissal of the case and entry of decision against the defaulting party. The notice was mailed to the Oxford, Wisconsin address. It was not returned to the Court as undeliverable and there is no other indication in the tax court’s records that petitioner did not receive this notice.
On September 2, 1987, September 16, 1987, and October 18, 1987, the Commissioner sent petitioner letters to the Oxford, Wisconsin address requesting him to contact the Commissioner for the purpose of preparing the case for trial. The September 16, 1987 letter was forwarded to an Akron, Ohio address petitioner used prior to his Oxford, Wisconsin address. All three letters were eventually returned to the Commissioner as undeliverable.
When the Commissioner attempted to verify petitioner’s address through computer records, it discovered that petitioner had used the Akron, Ohio address for his 1985 and 1986 tax returns. In October of 1987, the Commissioner learned from the Federal Inmate Locator Service that petitioner had been released on parole from a halfway house in Ohio on May 9, 1984. The Commissioner sent another letter along with a copy of respondent’s trial memorandum on October 26, 1987 to the Akron, Ohio address. Petitioner did not reply.
Petitioner failed to appear for trial on November 2, 1989. Thereafter, upon motion of the Commissioner, the tax court entered a default against the petitioner under Rule 123(a)2 of the Rules of Practice and Procedure of the United States Tax Court (“Tax Ct.R.”) for the full amount of the deficiency and fraud penalties, based solely upon the well-pleaded allegations in the Commissioner’s answer. Specifically, the tax court held that petitioner had failed to “otherwise proceed” under Tax Ct.R. 123(a) by failing to communicate with the court, by failing to comply with the pretrial order regarding preparation of a stipulation of facts as required under Tax Ct.R. 91(a), and by failing to appear at trial. In granting the fraud penalties, the court in a reviewed opinion,3 expressly overruled its earlier decision in Miller-Pocahontas Coal Co. v. Commissioner, 21 B.T.A. 1360 (1931), which held that a taxpayer cannot be held liable for an addition to tax for fraud unless the Commissioner introduces into the record evidence of fraud sufficient to carry the Commissioner’s burden of proof.4
[1474]*1474The tax court entered its decision against petitioner for the deficiencies in and addition to tax on December 27, 1988. Before that decision became final, see 26 U.S.C. § 7481(a)(1), petitioner timely filed a motion to set aside the default pursuant to Tax Ct.R. 123(c),5 claiming that he had first become aware of the opinion granting the Commissioner’s motion to hold petitioner in default and enter a decision against him when he read a newspaper article discussing the decision on January 4, 1989. That motion was denied on April 17, 1989.6 This appeal followed.
II.
The United States Courts of Appeals have exclusive jurisdiction to review decisions of the tax court, except as provided in 28 U.S.C. § 1254, “in the same manner and to the same extent as decisions of the district courts in civil actions tried without a jury.” 26 U.S.C. § 7482(a); Headrick v. Commissioner, 918 F.2d 1263, (6th Cir.1990); Threlkeld v. Commissioner, 848 F.2d 81, 83 (6th Cir.1988). Thus, a tax court’s findings of fact can be disturbed only if they are clearly erroneous; questions of law are subject to de novo review. Estate of Shafer v. Commissioner, 749 F.2d 1216, 1218 (6th Cir.1984) (citation omitted); see also Headrick, supra, (questions of law reviewed de novo). Upon such review, the courts of appeals “shall have power to affirm or, if the decision of the Tax Court is not in accordance with law, to modify or to reverse the decision of the Tax Court, with or without remanding the case for a rehearing, as justice may require.” 26 U.S.C. § 7482(c)(1). Petitioner’s appeal is properly before this court, since his legal residence for purposes of venue on appeal is Ohio, the state where he lived prior to incarceration and after being paroled and that state in which he still owns property. See 26 U.S.C. § 7482(b).
A.
The first issue presented for consideration is whether the tax court properly entered a default judgment granting fraud penalties, based exclusively on the allegations in the Commissioner’s answer, where the taxpayer filed a reply to the Commissioner’s answer and a response to requests for admissions, but subsequently failed to participate in preparing a stipulation of facts and to appear for trial.
In this case the Commissioner issued a notice of deficiency to the petitioner in which he asserted that there were deficiencies in the petitioner’s income taxes for 1972 and 1973. The Commissioner’s deficiency determinations are presumed correct. The taxpayer therefore bears the burden of proving otherwise. Helvering v. Taylor, 293 U.S. 507, 515, 55 S.Ct. 287, 291, 79 L.Ed. 623 (1935); Welch v. Helvering, 290 U.S. 111, 115, 54 S.Ct. 8, 9, 78 L.Ed. 212 (1933); Davis v. Commissioner, 674 F.2d 553, 553 (6th Cir.1982); Tax Ct.R. 142(a). The Commissioner also issued a 50 percent penalty for fraud with respect to the deficiencies pursuant to 26 U.S.C. [1475]*1475§ 6653(b).7 In contrast with the deficiency-assessment, the burden of proof as to the fraud penalty is on the Commissioner, who must prove the fraud by “clear and convincing” evidence. 26 U.S.C. § 7454; Tax Ct.R. 142(a);8 Traficant v. Commissioner, 884 F.2d 258, 264 (6th Cir.1989). The addition to tax for fraud is a civil provision, enacted “primarily as a safeguard for the protection of the revenue and to reimburse the Government for the heavy expense of investigation and the loss resulting from the taxpayer’s fraud.” Helvering v. Mitchell, 303 U.S. 391, 401, 58 S.Ct. 630, 634, 82 L.Ed. 917 (1938) (footnote omitted).
In Miller-Pocahontas Coal, supra, the Board of Tax Appeals9 held that a taxpayer who filed a petition attacking both the deficiency and the penalty assessments against him, but who failed to appear for trial could not be held liable for an addition to tax for fraud without the formal introduction into the record of such evidence sufficient to support the respondent’s burden of proof. The Board refused to assess fraud penalties against the petitioner, since the Commissioner offered no proof of fraud to sustain the penalty. Absent the tax court’s decision in the instant case to overturn its earlier decision, Miller-Pocahontas Coal would require us to vacate the tax court’s assessment of fraud penalties against the petitioner since here the Commissioner likewise did not introduce into the record evidence of fraud. Because this issue presents a question of law, we review it de novo. Headrick, supra; Shafer, supra.
It is well established that courts have inherent power to dismiss and/or enter a default when a party disobeys a court order or otherwise interferes with the efficient administration of justice. Link v. Wabash R.R. Co., 370 U.S. 626, 630-31, 82 S.Ct. 1386, 1388-89, 8 L.Ed.2d 734 (1962); Harris v. Callwood, 844 F.2d 1254, 1255 (6th Cir.1988); accord Coston v. Detroit Edison Co., 789 F.2d 377, 379 (6th Cir.1986); see also Roland v. Salem Contract Carriers, Inc., 811 F.2d 1175, 1177-78 (7th Cir.1987) (“[t]he power to sanction through dismissal is essential to the district courts’ ability to manage efficiently their heavy caseloads and thus protect the interest of all litigants”). Also, pursuant to the authority granted it by Congress, the tax court has enacted the “Rules of Practice and Procedure of the United States Tax Court Rules.” 26 U.S.C. § 7453; see also, 26 U.S.C. foil. § 7453; 60 T.C. 1057 (1973); accord, Louisville Builders Supply Co. v. Commissioner, 294 F.2d 333, 339 (6th Cir.1961) (tax court’s powers are limited to those given by specific acts of Congress and by court’s own rules adopted pursuant to congressional authorization plus such inherent powers as may be in a quasi judicial body). The Rules govern practice and procedure in all cases and proceedings in the tax court, Tax Ct.R 1(a), and are to be construed “to secure the just, speedy and inexpensive determination of every case.” Tax Ct.R. 1(b). The tax court rules are modeled after the Federal Rules of Civil Procedure. See Introduction to Rules of Practice and Procedure of the United [1476]*1476States Tax Court, 60 T.C. 1057, 1057 (1973) (the rules “draw upon the Federal Rules of Civil Procedure to the extent that they were thought to be suitably adaptable to the special nature of litigation in the Tax Court”).
Tax Ct.R. 123(b), which is derived from Fed.R.Civ.P. 41(b), provides that the court may dismiss a case and enter a decision against the petitioner “[f]or failure of a petitioner properly to prosecute or to comply with these Rules or any order of the Court_” Tax Ct.R. 123(b). Thus, because the petitioner bears the burden of proof with respect to the deficiency assessment, dismissal of the petition is an appropriate sanction for his noncompliance. See Bosurgi v. Commissioner, 87 T.C. 1403, 1407 n. 3 (1986).
The rule which immediately concerns us is Tax Ct.R. 123(a),10 which provides that the tax court may in its discretion hold a party in default for failure to “plead or otherwise proceed as provided by these Rules [the Tax Court Rules] or as required by the Court,” and that the court may enter a decision against the defaulting party or impose other sanctions, such as those provided in Rule 104. Tax Ct.R. 123(a). Rule 123(a) is derived from Rules 55(a) and (b) of the Federal Rules of Civil Procedure. See Note to 123(a), 60 T.C. 1057, 1129 (1973); Bosurgi, 87 T.C. 1403. By analogy to Fed.R.Civ.P. 55(a), the party who bears the burden of proof may move for entry of default. Bosurgi, 87 T.C. at 1407. Thus, the tax court acted correctly insofar as it employed Rule 123(a) to sanction petitioner’s non-cooperation with respect to the fraud penalty, since it is the Commissioner who bears the burden of proof on that issue.
As one ground for overruling Miller-Pocahontas Coal, the Smith majority held that its adoption of Tax Ct.R. 123(a), effective January 1, 1974, implicitly overruled its earlier decision to the extent Miller-Pocahontas Coal adopted a per se rule requiring that evidence of fraud be formally introduced in every ease. In support, the court pointed to the language of Rule 123(a) which provides that the court “may, in its discretion, conduct hearings to ascertain whether a default had been committed.” Tax Ct.R. 123(a) (emphasis added). We believe that from the tax court’s inherent and statutory authority to regulate its docket and adopt rules of procedure flows the ability to effectively overrule a prior decision that has become outmoded and serves as an impediment to the court’s mission of securing just, speedy and inexpensive determination of all cases before it. This is especially true when the rule had no counterpart in prior tax court rules and therefore could not have been a factor in the earlier court’s determination. See Note to Rule 123(a), 60 T.C. at 1130.
Secondly, as the tax court stated, the rule of Miller-Pocahontas Coal has been nullified in practice by other tax court procedures. As noted above, the tax court has already relieved the Commissioner of the burden of putting on his case for the addition to tax for fraud in actions involving the use of deemed admissions (Rules 37(c), 90(c), or 91(f)), and sanctions (Rule 104(c)(3)).11 As the majority in the case below noted:
When any party has failed to plead or otherwise proceed as provided by these Rules or as required by the Court, he may be held in default by the Court either on motion of another party or on the initiative of the Court. Thereafter, the Court may enter a decision against the defaulting party, upon such terms and conditions as the Court may deem proper, or may impose such sanctions (see, e.g., Rule 104) as the Court may deem appropriate. The Court may, in its discretion, conduct hearings to ascertain whether a default has been committed, to determine the decision to be entered or the sanctions to be imposed, or to ascertain the truth of any matter.
[1477]*1477Because the taxpayer’s failure to respond (after failing to cooperate with respondent in the pretrial process) occurs no later in the proceedings than the taxpayer’s failure to appear at trial in a case in which the Commissioner makes no such attempt, the only reason to treat one failure to respond differently from the other is that one provides “proof” of fraud through deemed admissions under our Rules while the other, theoretically, does not.... [W]e think that distinction to be superannuated and without relevance in present-day proceedings in this Court.
Smith, 91 T.C. at 1055-56. Since the effect of a default is to establish the well-pleaded facts of the non-defaulting party, the establishment of such facts through a default is no different than establishing such facts through deemed admissions. Id. at 1052. See Bosurgi, supra, (where tax court entered default without a hearing against taxpayer even though the Commissioner had burden of proof on the issue of transferee liability). Thus, as aptly stated by the tax court below, when a taxpayer fails to cooperate with the Commissioner and the tax court it is “patently absurd” to:
“recite a litany of ‘deemed’ admissions, ‘find’ facts not disputed, and then ‘decide’ the case as best we can, issuing a written opinion in every case. Often we have a ‘trial’, the respondent putting on his case without the presence or participation of the taxpayer. These little one-act pantomimes complete with briefs and an opinion are a charade in which we can no longer indulge. The enormous growth in our caseload requires that we recognize the inconvenience these useless and futile histrionics impose on other citizens having business before this Court.”
Smith, 91 T.C. at 1058 (citing Doncaster, 77 T.C. at 344-45 (Wilbur, J., concurring) (citation omitted)). See also Bosurgi, supra, 87 T.C. at 1408 (“[i]f a taxpayer does not think well enough of his case to defend it where the Government has the burden of proof, this Court should default him. To hold a trial in a case abandoned by the taxpayer is at best an indulgence of archaic manners and at worst an insult to the taxpayers who have a rightful claim on this Court’s time”).
Third, as held by the tax court, changes in the revenue code have undercut the rationale of Miller-Pocahontas Coal. In Miller-Pocahontas Coal, the Board of Tax Appeals declined to grant the fraud penalty in the default context because it determined that the revenue acts made a clear distinction between a deficiency in tax and a penalty, and that section 906(c) of the Revenue Act of 1924, 43 Stat. 253, 336, as amended by the Revenue Acts of 1926 and 1928, “provide[d] that a dismissal shall require an affirmance of the deficiency only.” [1478]*147821 B.T.A. at 1361. The Board further observed that a fraud penalty is not part of the deficiency because the burden of proof as to the fraud issue is on the Commissioner, not the taxpayer. However, as currently pointed out by the Smith majority, under present code, section 666212 of the IRC (formerly 6659) provides that “additions to the tax, additional amounts, and penalties ... shall be assessed, collected, and paid in the same manner as taxes.” 26 U.S.C. § 6662. Moreover, the legislative history reflects that the provision is clearly intended to cover deficiency procedures, including proceedings in the tax court. See H.Rept. 1337, 83d Cong., 2d Sess. A420 (1954); S.Rept. 1622, 83d Cong., 2d Sess. 595 (1954). See also H.Rept. 1217, 86th Cong., 2d Sess. 2 (1960), 1960-1 C.B. 843. Thus, we agree with the tax court’s conclusion that the “deficiency” rationale of Miller-Pocahontas Coal is no longer valid. 91 T.C. at 1054.
Judge Shields argues in his dissent that Rule 123(a) does not allow for entry of default after the taxpayer files a reply (as was the case here), based on an analogy to Fed.R.Civ.P. 55(a);13 in that the phrase "otherwise defend” of Rule 55(a) refers to defenses and objections available to a defendant by motion prior to filing an answer.14 See Smith, 91 T.C. at 1062-66. We conclude, however, that the language “plead or otherwise proceed” as used in Rule 123(a) is sufficiently distinct from the language “plead or otherwise defend” as used in Fed.R.Civ.P. 55(a) such that a failure to participate in the pretrial proceedings or to appear at trial may constitute a failure to “proceed” for purposes of Rule 123(a). In any event, the Federal Rules of Civil Procedure, while persuasive, are not binding on the tax court. Commissioner v. Licavoli, 252 F.2d 268 (6th Cir.1958); Lasky v. Commissioner, 235 F.2d 97 (9th Cir.1956) aff'd 352 U.S. 1027, 77 S.Ct. 594, 1 L.Ed.2d 598 (1957); Starr v. Commissioner, 226 F.2d 721 (7th Cir.1955), cert. denied, 350 U.S. 993, 76 S.Ct. 542, 100 L.Ed. 859 (1956); Katz v. Commissioner, 188 F.2d 957 (2d Cir.1951). Furthermore, this court has held that with regard to the tax court’s interpretation and application of its own procedural rules, an abuse of discretion standard is to be applied. Estate of Shafer, supra, 749 F.2d at 1216. We find no abuse of that discretion in the instant case.
Finally, we note that in order to safeguard against the automatic imposition of the fraud addition, the court admonished that, “the Commissioner’s pleadings must allege specific facts sufficient to sustain a finding of fraud before he will be entitled to a decision that includes an addition to tax for fraud upon the failure of a taxpayer to appear for trial.” Smith, 91 T.C. at 1058. Here, the tax court found that the Commissioner’s specific allegations, once taken to be true by petitioner’s default, were sufficient to carry his burden of prov[1479]*1479ing that the deficiencies resulted from the taxpayer’s fraud. This court has articulated a number of factors which indicate fraud under 26 U.S.C. § 6653(b); including: (1) the taxpayer’s failure to file returns; (2) failure to report income over an extended period of time; (3) taxpayer’s failure to furnish the government with access to his records; (4) failure to keep adequate books and records; and (5) evidence of taxpayer’s experience and knowledge, especially of tax laws. Solomon v. Commissioner, 732 F.2d 1459, 1461 (6th Cir.1984) (citations omitted); See also United States v. Walton, 909 F.2d 915, 926 (6th Cir.1990). The tax court first evaluated the Commissioner’s net worth analysis, as set forth in his answer, under the standards enunciated in Holland v. United States, 348 U.S. 121, 132-38, 75 S.Ct. 127, 133-37, 99 L.Ed. 150 (1954), which requires the Commissioner to establish, with reasonable certainty, an opening net worth, and that he has either conducted a reasonable investigation of leads which would negate possible sources of non-taxable income or establish a likely source of unreported taxable income. See also Brooks v. Commissioner, 82 T.C. 413, 431-32 (1984) aff'd, 772 F.2d 910 (9th Cir.1985). The tax court concluded that the Commissioner’s net worth analysis as set forth in his answer established a pattern during the taxable years at issue, and that the pattern of acquiring substantial assets while reporting nominal income on his returns was evidence of fraud and the court further noted that petitioner’s failure to keep records was also a badge of fraud. After careful review of the record, we find that the tax court’s factual findings were not “clearly erroneous” and that it did not err in finding the existence of fraud on the part of the petitioner.
We are not unmindful of the heavy burden placed upon the tax court by doctrine of stare decisis and that any decision to depart from the doctrine requires “special justification.” Arizona v. Rumsey, 467 U.S. 203, 212, 104 S.Ct. 2305, 2311, 81 L.Ed.2d 164 (1984). On the other hand, stare decisis is not “an inexorable command,” and the Supreme Court has indicated that a departure may be justified when a court feels obliged “to bring its opinions into agreement with experience and with facts newly ascertained.” Vasquez v. Hillery, 474 U.S. 254, 266, 106 S.Ct. 617, 624-25, 88 L.Ed.2d 598 (1986) (quoting Burnet v. Coronado Oil and Gas Co., 285 U.S. 393, 412, 52 S.Ct. 443, 625, 76 L.Ed. 815 (1932) (Brandéis, J., dissenting). Further, we know of no authority which prevents a court, sitting en banc, from overruling one of its prior decisions when it has determined that the rule is outdated and an impediment to legal process. We therefore find that the court has provided adequate justification for its decision to formally overrule Miller-Pocahontas Coal since the rationale underlying the decision has been undermined by subsequent procedural and statutory developments, and because continued adherence to the rule interferes with efficient administration of the tax court.
B.
Petitioner’s second argument on appeal is that the tax court erred in denying his timely motion to set aside the default under Tax Ct.R. 123(c), which provides that a default may be set aside “for reasons deemed sufficient by the court and upon motion expeditiously made.” This court has indicated that a “glaring abuse” of discretion is not required for reversal of the harsh sanction of default. United Coin Meter v. Seaboard Coastline R.R., 705 F.2d 839, 846 (6th Cir.1983) (citation omitted).
We have articulated the following factors to be considered in determining whether to set aside default: 1) whether the non-defaulting party will be prejudiced; 2) whether the defendant has a meritorious defense; and 3) whether the culpable conduct of the defendant led to the default. United Coin Meter, supra, 705 F.2d at 845 (citations omitted). See also Shepard Claims Serv., Inc. v. William Darrah & Assoc., 796 F.2d 190, 194-95 (6th Cir.1986); INVST Financial Group, Inc. v. Chem-Nuclear Systems, Inc., 815 F.2d 391, 399 (6th Cir.), cert. denied, 484 U.S. 927, 108 S.Ct. 291, 98 L.Ed.2d 251 (1987); Berthel[1480]*1480sen v. Kane, 907 F.2d 617, 620 (6th Cir.1990), reh’g denied (Sept. 10, 1990). In Shepard Claims Serv., supra, we further explained:
“Where the defaulting party and counsel have not shown disrespect for the court, or have given evidence of respect for the court’s process by their haste in acting to set aside the default, the courts have been inclined toward leniency- Clear-
ly, however, the court may refuse to set aside a default, where the defaulting party has no meritorious defense, where the default is due to willfulness or bad faith, or where the defendant offers no excuse at all for the default.” (Footnotes omitted).
We do not believe it appropriate to attempt a precise definition of “culpable conduct.” Where the party in default satisfies the first two requirements for relief and moves promptly to set aside the default before a judgment is entered, the district court should grant the motion if the party offers a credible explanation for the delay that does not exhibit disregard for the judicial proceedings.
796 F.2d at 194-95 (quoting J. Moore, 6 Moore’s Federal Practice 55.01[2] at 55-61, 62 (1985 ed)).
Here the tax court found that there was no indication in the record that petitioner had acted willfully or in bad faith with respect to the default. It did find however that the petitioner failed to exhibit that he had a meritorious defense. We have stated that:
[A] defense is sufficient if it contains even a hint of a suggestion which, proven at trial, would constitute a complete defense. The key consideration is to determine whether there is some possibility that the outcome of the suit after a full trial will be contrary to the result achieved by the default.
INVST Financial Group, Inc., 815 F.2d at 399 (internal citations and quotations omitted). The record reflects the tax court’s findings that petitioner offered “no explanation or reason for the asserted difference between his net worth computation and respondent’s” and “no suggestion that he has any evidence to support his computation.” See Smith, 57 T.C.M. at 132. Indeed, the only material allegation in the record is defendant’s assertion in his reply to the Commissioner's answer, that his net worth was approximately one third of the amount asserted by respondent. Petitioner’s general assertion regarding his net worth is tantamount to a general denial and, as such, did not amount to even a “hint of a suggestion” that petitioner could dispute the allegations of the government’s answer. See INVST Financial Group, supra, 815 F.2d at 399. We therefore find that the tax court did not abuse its discretion concluding that petitioner had failed to present a meritorious defense.
As a second ground for denying petitioner’s motion to set aside default, the tax court found that petitioner had failed to advance a credible explanation for his disregard of judicial proceedings. The tax court rejected petitioner’s assertion that Commissioner knew or could have known of petitioner’s correct address and was therefore responsible for petitioner’s failure to receive notice of the setting of his case for trial. It observed that it was incumbent on petitioner to notify the court of a change in his address pursuant to Tax.Ct.R. 21(b)(4) and that as petitioner had selected that forum to review his tax liability, he was bound by its Rules. 57 T.C.M. at 132. We agree with the tax court’s conclusion that petitioner’s failure to keep the Court advised of his address over a seven year period clearly violated its Rules and displayed “a reckless disregard for the petition he filed in the instant case and for the judicial proceedings he instituted by filing his petition.” Id. (citing Shepard Claims Serv., 796 F.2d at 194) (emphasis in tax court opinion).
Finally, the tax court concluded that prejudice would result to the respondent, the court, and the other taxpayers in reviewing litigation. In sum, we find no abuse of discretion in the tax court’s denial of petitioner’s motion to set aside the default judgment. Accordingly, for all the foregoing reasons we AFFIRM the decision of the tax court.
