*539 MEMORANDUM OPINION
This interpleader action was tried before me without a jury by the consent of the parties. (Paper Nos. 50-51). The case arises out of multiple claims to funds owed by mechanical contractor Mecco, Inc. to a sheet metal subcontractor known as “Me-talMax” 1 for heating, ventilation and air conditioning work performed on various commercial construction projects. Metal-Max was owned and operated by Clifford A. “Tony” Clarkson, who also owned and operated a company known as CAC Balancing, Inc. The only two interpleader defendants remaining in this case are Colombo Bank, FSB, a secured creditor of CAC Balancing, Inc., and the United States Internal Revenue Service, 2 which holds tax liens against both CAC Balancing, Inc. and Tony Clarkson as an individual. At the conclusion of the trial in this case, I ruled from the bench that Colombo Bank was entitled to the interpleader funds at issue, but indicated that I would issue a written opinion explaining my decision. This memorandum opinion provides that explanation.
I. Background
A. CAC and MetalMax
Clarkson incorporated CAC Balancing, Inc. (“CAC”) in 1996. (Tr. 20). 3 He was the sole shareholder, officer and director of the company, which performed air and water balancing for commercial HVAC systems. (Tr. 20, 61-62). Sometime around the year 2000 Clarkson decided to expand into sheet metal installation, and began performing sheet metal and duct work under the name “MetalMax.” (Tr. 21). He wrote checks, signed contracts, and issued invoices under that name. (IRS Exs. 5-7). Clarkson testified that he chose the name MetalMax because wanted his sheet metal division to operate under a name that customers would associate with sheet metal, rather than balancing work. (Tr. 21). Both Clarkson and Mecco owner William Bradley also testified that it is common practice for mechanical contractors to perform sheet metal work and balancing work under separate names because many project engineers and architects will not hire the same company to balance an HVAC system that it has installed. (Tr. 21, 73-74). To do so, as Mr. Bradley described it, would be “like the fox guarding the hen-house.” (Tr. 74). 4
Clarkson testified that he considered CAC and MetalMax to be one and the same, and that he held himself out as president of both. The names of both CAC and MetalMax were listed on Clark-son’s Maryland and Virginia business licenses. Although CAC and MetalMax had separate phone lines, both were operated out of the same location in College Park, Maryland and the same employee answered both lines. (Tr. 66) Clarkson han- *540 died all of the billing and kept track of the receivables for both CAC and MetalMax. ' He kept only one set of books for both, in which he treated the accounts receivable of MetalMax as belonging to CAC. (Tr. 27). The bank introduced into evidence an accounts receivable report generated by Clarkson on October 9, 2003 using the QuickBooks computer program, (hereinafter “the QuickBooks report”). On the QuickBooks report, work performed by CAC was identified by the term “air & water,” while MetalMax work was designated as “sheetmetal.” (Tr. 36. Colombo Ex. 6). In addition, although CAC and MetalMax had separate bank accounts, both were set up under CAC’s federal tax identification number. (Tr. 24). Clarkson endorsed all checks for deposit in these accounts with a stamp bearing CAC’s name and this single tax identification number. (Tr. 54).
Clarkson testified that only CAC issued IRS Form W-2’s to employees of both CAC and MetalMax. (Tr. 25). Accordingly, he filed only one set of federal and state tax income tax returns for both CAC and MetalMax under the name of CAC. (Tr. 27). Significantly, the federal tax liens at issue in this interpleader action are the result of unpaid income tax withholding, Social Security, and federal unemployment taxes attributable to both CAC and Metal-Max employees. (Tr. 28-29)
Although CAC and MetalMax each entered into a separate collective bargaining agreement with the Sheet Metal Workers International Union, Clarkson testified that he entered into the separate agreement for MetalMax at the union’s request. (Tr. 56-57). Although there were two union contracts, Clarkson made all required contributions to the union benefit fund and submitted all corresponding reports under the name CAC. (Tr. 57). Likewise, when working on projects subject to the federal prevailing wage law, Clarkson submitted only one set of certified weekly payroll reports in the name “CAC Balancing, Inc. / MetalMax Sheet Metal Works.” (Tr. 51-52).
Finally, CAC filed a lawsuit against Mecco in Virginia state court in January 2004 alleging breach of contract and quantum meruit. (Tr. 58-59, Colombo Ex. 12). The lawsuit was brought on behalf of “CAC Balancing, Inc., t/a MetalMax.” Hd.)
On July 14, 2000, Colombo Bank loaned CAC $250,000 secured by a promissory note and security agreement that attached to all of “all inventory, chattel paper, accounts, equipment, and general intangibles.” (Colombo Exs. 1, 3). Colombo advanced CAC an additional $70,883.84 secured by a second promissory note and security agreement on August 31, 2000. (Colombo Ex. 2). The bank perfected its security interest in the aforementioned collateral by filing a financing statement with the Maryland State Department of Assessments and Taxation (“SDAT”) on August 15, 2000. 5 (Colombo Ex. 4).
In March 2003 the IRS filed a tax lien for unpaid employee withholding in the amount of $330,726.71 against CAC in the Circuit Court for Anne Arundel County, Maryland. (IRS Ex. 1). The IRS filed another lien against CAC for $97,404.72 in November of that year. (IRS Ex. 2). In July 2005, the IRS filed tax liens against Clarkson as an individual in both the Circuit Court for Howard County and Prince George’s County, Maryland in the amount of $319,568.37. (IRS Ex. 4).
*541 On October 7, 2002, CAC forfeited its corporate charter to operate in the State of Maryland. (IRS Ex. 12). Shortly thereafter, in early 2003, CAC and Metal-Max ceased operations. (Tr. 51). CAC defaulted on the loans and it is undisputed that, at the time of trial, CAC owed the bank a balance of $184,648.93, exclusive of interest, attorneys’ fees and costs. On August 10, 2004, CAC entered into a settlement agreement with the bank that expressly authorized Colombo to, among other things, collect any sums owed to CAC by its account debtors. (Colombo Ex. 11).
B. Mecco, Inc.
Mecco is a mechanical contractor that subcontracted both commercial HVAC installation and balancing work to MetalMax and CAC, respectively. (Tr. 31). These jobs included “1722 Eye Street,” “B & O Railroad,” “F.O.B. # 2” and “Kilpatrick Stockton.” (Tr. 39, Colombo Ex. 6). The QuickBooks report indicates that the work performed for Mecco was “sheetmetal” work, and that CAC’s outstanding accounts receivable for these jobs totaled $251,489.90. Id. In addition, the report indicates on what date Mecco was billed for each job performed and on what date the account receivable was due to be paid. Id. Clarkson testified that all work reflected on an invoice was complete by the date that the invoice was generated. (Tr. 41-42). The QuickBooks report therefore indicates that CAC and/or MetalMax performed $238,354.90 worth of work for Mec-co before its charter was forfeited, and $13,135.00 after the October 7, 2002 forfeiture date. (Colombo Ex. 6). In any event, Clarkson testified that all work for Mecco was completed by December 11, 2002. (Tr. 40).
When Mecco became aware of the competing interests in these funds it filed the instant interpleader action under Md. Rule 2-221. 6 (See Compl.). In the ' complaint, however, Mecco claimed that it owed only $80,694 to MetalMax, and asserted that it had paid all funds due and owing to CAC. (Comply 12-13).
Colombo, asserting its rights as both an assignee under the settlement agreement and a secured creditor of CAC’s accounts receivable under Md.Code Ann. Comm. Law § 9-607, 7 filed a counterclaim against Mec-co for breach of contract, alleging that “Mecco is indebted to CAC for labor and materials in an amount in excess of $80,694.00.” (Counterclaim ¶ 9). That counterclaim subsequently was settled and Mecco was dismissed from the case on March 19, 2007. (Paper No. 92). Under that settlement agreement, Mecco paid an additional $76,806 in interpleader funds into the Court’s registry for a total of $157,500. (See Paper No. 97)
II. Discussion
This interpleader action presents several questions of law and one mixed issue of law and fact. Turning first to the mixed question of law and fact, the Court must determine the relationship between CAC and MetalMax and the affect that this *542 relationship has on the priority of the competing security interests in this case. If they are a single entity, the parties agree that the bank’s security interest has priority over the original $80,694 in interpleader funds to the extent that the work giving rise to those accounts receivable was performed before CAC forfeited its corporate charter. If not, the two are separate and the bank has no interest in the money due and owing from Mecco to MetalMax because its security interest is limited to CAC’s accounts receivable. In that case the IRS will prevail by virtue of its tax liens against Clarkson as an individual. If CAC and MetalMax are found to be one entity, the next question of law involves what, if any, affect the forfeiture of CAC’s corporate charter has on the bank’s priority over accounts receivable arising out of work performed after the forfeiture date. Finally, the Court must determine who has priority over the additional $76,806 in in-terpleader funds resulting from the settlement of the bank’s counterclaim against Mecco. The IRS argues that, regardless of the bank’s entitlement to the original interpleader funds, the tax liens have priority in the additional settlement funds, which it argues, did not come into existence, or become “choate,” until the date of the settlement.
A. The Priority of Federal Tax Liens
Before I discuss the relationship between CAC and MetalMax, it is important to understand why this relationship is significant for the purpose of determining the priority of the competing liens at issue in this interpleader action. In this case, the Court must ultimately resolve a priority dispute between a perfected security interest and a federal tax lien, an undertaking that requires to Court to “enter ... the tortured meanderings of federal tax lien, intersected now by the somewhat smoother byway of the Uniform Commercial Code.”
Texas Oil & Gas Corp. v. United States,
An individual’s failure to pay taxes results in a federal tax lien against “all property and rights to property, whether real or personal, belonging to such person.”
8
26 U.S.C. § 6321. This federal tax lien is not valid against competing security interests until it is filed with the clerk of the district court in the jurisdiction where the property subject to the lien is located. 26 U.S.C. § 6322(f)(1)(B). “Federal tax liens do not automatically have priority over all other liens.”
United States v. McDermott,
The Federal Tax Lien Act, 26 U.S.C. § 6321 et seq. (“FTLA”), provides a limited exception to this rule for certain secured commercial financing transactions. 26 U.S.C. § 6323(c).
See also McDermott,
For the purposes of the FTLA, a commercial transactions financing agreement is one in which the secured party makes a loan to the taxpayer secured by “commercial financing security.” Commercial financing security includes accounts receivable. See 26 U.S.C. § 6323(c)(2)(A) and (C). It is undisputed that the bank’s security interest in CAC’s accounts receivable is a qualified commercial financing transactions agreement for the purposes of the FTLA.
Under this statutory exception to the “first in time” preference accorded to federal tax liens, a preexisting security interest, such as that held by the bank, will be given priority over tax liens to the extent they are perfected prior to, or within 45 days after, the filing of a tax lien by the IRS. 26 U.S.C. §§ 6323(a); 6323(c)(1)(A) and (2)(A). Liens against accounts receivable are deemed to be perfected and to comply with the doctrine of choateness when the work giving rise to the account receivable is performed.
See, e.g.,
29 C.F.R. § 301.6323(c)-l(d)(“An account receivable ... is acquired by a taxpayer at the time, and to the extent, a right to payment is earned by performance.”).
See also Bremen Bank & Trust Co. v. United States,
*544 The bank perfected its security interest in CAC’s accounts receivable under Maryland law by filing a financing statement with SDAT in August 2000 and filing a continuation statement in March 2006. CAC/MetalMax performed all work under its contracts with Mecco on or before December 11, 2002. The IRS, however, did not file its first tax lien until April 2003. If CAC and MetalMax are a single entity, the bank’s perfected security interest attached to CAC’s accounts receivable at the time the work was performed for Mecco by MetalMax, which occurred no later than December 11, 2002. If this is the case, then the bank’s security interest will take priority over the federal tax liens because its interest attached to the property and was “choate” well before the IRS filed notice of its tax liens.
B. CAC and MetalMax Are A Single Entity Jointly Owned and Operated by Clifford Clarkson
With, the foregoing in mind, the IRS argues that CAC and MetalMax are two separate entities, with MetalMax operating as a separate sole proprietorship run by Clarkson. Under this reasoning, the IRS argues that the bank has no entitlement to the interpleader funds because Mecco owes those monies to MetalMax, rather than CAC. Accordingly, the IRS asserts that the tax liens against Clarkson individually take priority over the bank’s security interest in CAC’s accounts receivable. For the reasons set forth below, I find that the facts do not support this argument, and conclude that CAC and Me-talMax are a single company.
The Court has not been provided with any authority, nor has it been able to locate any through its own research, to support the proposition that an informal entity such as MetalMax, closely related to a formally incorporated entity such as CAC, should be treated as a sole proprietorship for the purpose of determining the competing interests of its creditors. The most analogous authority is found in those cases in which the court is asked to “pierce the corporate veil” by treating separate legal entities as one for the purpose of imposing liability on a parent for the actions of its subsidiary, or upon an individual for the actions of a corporation. In this context, the Maryland Court of Special Appeals observed:
The corporate entity is disregarded ... wherein it is so organized and controlled, and its affairs are so conducted, as to make it merely an instrumentality, agency, conduit, or adjunction of another corporation.
Dixon v. Process Corp.,
(1) the presence in both corporations of the same officers or directors; (2) common shareholders; (3) financial support of the subsidiary’s operations by the parent; (4) underwriting the incorporation and purchase of all of the capital stock of the subsidiary by the parent corporation; (5) the fact that the subsidiary was organized with a grossly inadequate capital structure; (6) a joint accounting and payroll system; (7) the subsidiary lacks any substantial business contacts save the parent and operates solely with assets conveyed by the parent corporation; (8) in the financial statements of the parent, the subsidiary is referred to as a division of the parent corporation or obligations are assumed to be those of the parent; (9) the property of the subsidiary is used by the parent corporation as its own; (10) the individuals who exercise operating control over the subsidiary exercise it in the *545 interest of the parent; and (11) failure to observe formal requirements in the operation of the subsidiary.

I find that these factors are instructive in analyzing the facts of this case. First, Clarkson was the principal of both CAC and MetalMax and exercised control over both. The two entities would have had the same officer, director and shareholder but-for the fact that MetalMax was not formally organized, which, in my view, provides further evidence that it was part of CAC. Next, Clarkson kept one set of books for both and, even though the two technically had separate bank accounts, and treated their receivables as the same. Both were listed on Clarkson’s only business license, and both were operated out of the same location. Although CAC and MetalMax had separate union contracts, all employee benefits were both paid and reported to one union fund. Moreover, CAC and Me-talMax made combined certified payroll reports to the DOL on Davis-Bacon Act projects. There also was testimony that some employees worked for both CAC and MetalMax. Finally, and perhaps most significantly, CAC and MetalMax had only one federal tax identification number, filed only one set of federal tax returns, and issued Form W-2s to employees of both companies in the name of CAC.
Regardless of whether Clarkson held out CAC and MetalMax to be two separate companies, the evidence presented makes clear that they were a single operation, and the fact that CAC operated under the trade name MetalMax does not, in and of itself, mean that the two are separate entities. Under Maryland law, there is no requirement that a contracting company register a trade name, nor was the bank required to include the trade name on its financing statement.
See
Md.Code Ann. Corps.
&
Assoos. § 1-406 (limiting the business that must register a trade name with the SDAT to those engaged in “mercantile, trading, or manufacturing”); Md. Code Ann. Comm. Law. § 9-503(b)(l)(a financing statement is not misleading if it does not include a trade name). Moreover, although there is no Maryland law directly on point, numerous other jurisdictions have held that operating under a trade name does not create a separate legal entity.
See, e.g., Bauer v. Pounds,
Accordingly, I find that MetalMax operated as a division of CAC and that the two were one entity. For that reason, the bank’s security interest in CAC’s accounts receivable has priority over all monies that became due prior to the date that CAC forfeited its corporate charter.
C. The Forfeiture of CAC’s Charter
Having determined that the bank’s security interest has priority over the federal tax liens with regard to accounts receivable attributable to work performed before CAC forfeited its corporate charter, the next issue presented is what affect, if any, this forfeiture has on the priorities of the parties with respect to accounts receivable attributable to work performed after the forfeiture date. The IRS argues that, because CAC lost its legal status as a corporation under Maryland law when it forfeited its
corporate
charter on October 7, 2002, any accounts receivable acquired after that date belong to Clarkson as an individual. See
Kroop & Kurland v. Lambros,
D. The bank’s security interest has priority over the settlement funds
Finally, the IRS claims that it has priority over the additional interpleader funds arising out of the settlement agreement between Colombo Bank, as a secured creditor of CAC Balancing, and Mecco, Inc. The IRS argues that the settlement funds did not come into existence until the settlement agreement was consummated on or about March 1, 2007, and therefore bank’s security interest in CAC’s accounts receivable did not attach or become “choate” until that date. Because the notice of the federal tax lien already had been filed at that time, the bank’s security interest and the federal tax liens would have attached at the same time and the federal tax liens would have prevailed. I disagree with the result urged by the IRS.
As discussed above, the bank’s security interest in CAC’s accounts receivable attached and became “choate” at the time CAC/MetalMax performed the work for Mecco giving rise to those accounts. When CAC defaulted on its promissory notes, Colombo, under Maryland law, had the right to step into CAC’s shoes and enforce the obligations of its account debtors. Md.Code Ann. Comm. Law § 9-607. 9 The bank did just that when it filed its counterclaim against Mecco alleging that Mecco owed CAC more than the $80,694 in interpleader funds identified in the complaint.
To suggest that the bank’s security interest in CAC’s accounts receivable somehow became inchoate by virtue of its efforts to collect those accounts receivable would render meaningless the great weight of authority cited above that holds an account receivable to be perfected, for the purposes of federal tax law, when the work giving rise to the account receivable is performed. See, e.g., 26 C.F.R. § 301.6323(c) — 1. Under this reasoning, any lien against accounts receivable would be deemed “inchoate” by a dispute over the amount owed by the account debtor.
The fact that the additional interpleader funds resulted from the settlement of a lawsuit does not change this result. Colombo’s counterclaim was brought for the sole purpose of collecting the accounts receivable owed to CAC by Mecco. The resulting settlement funds are proceeds of those accounts receivable.
See
Md.Code Ann. Comm. Law § 9-102(65)(defining proceeds as “whatever is collected on, or distributed account of, collateral”). Although the settlement funds themselves did not
*547
come into existence until after the tax liens were filed, the bank’s security interest in the underlying accounts receivable existed, attached, and were choate for the purposes of the FTLA when CAC/MetalMax performed the work for Mecco giving rise to the accounts receivable. 26 U.S.C. § 6323(h).
Cf. PPG Industries, Inc. v. Hartford Fire Ins. Co., et al.,
The IRS has cited several cases holding that a security interest does not attach to settlement funds until those funds are realized. Those cases are distinguishable because, even though they discuss the priority of tax liens over negotiated settlements, the underlying security interests are distinguishable from the bank’s interest in the present case. For example,
United States v. McDermott,
that provision [§ 6323(c)(1) ] protects certain security interests that, like the after-acquired-property judgment lien here, will have been recorded before the filing of the tax lien, and will attach to the encumbered property after the filing of the tax lien, and simultaneously with the attachment of the tax lien. According special priority to certain state security interests [i.e. commercial financing transactions] ... presumes that otherwise the federal tax lien would prevail.

Likewise,

there is no showing in this record that the mortgagee had become obligated to pay and had paid any sum of money for *548 services performed prior to the filing of the federal tax lien.

IV Conclusion
For the foregoing reasons, I find that the bank’s security interest in CAC’s accounts receivable has priority over the entire $157,500 in interpleader funds. A separate order has previously issued directing the Clerk of the Court to disperse those funds to Colombo Bank consistent with this opinion.
