delivered the opinion of the court:
Defendant, Max L. Bublick, appeals from a judgment holding him personally liable as an officer of defendant Joseph Bublick & Sons, Inc. (corporation) for *107,932.73 in unpaid retailers’ occupation taxes. He contends that the evidence did not establish (1) that plaintiff instituted proper proceedings for collection of the unpaid taxes from the corporation before proceeding against him personally, nor (2) that he wilfully failed to file the correct tax returns.
Plaintiff’s complaint, filed January 17, 1974, alleged in Count I that the corporation sold tangible personal property for use and consumption during the period from July 1969 thru April 1972; that it failed to perform its statutory duty to file correct forms showing its retail sales and to pay a tax as required under the Retailers’ Occupation Tax Act (Ill. Rev. Stat. 1971, ch. 120, par. 440-453); and that *92,092.35 plus interest, less *5,000 paid on account of said liability by the corporation, was due and owing. In Count II, plaintiff alleged, inter alia, that defendants Max L. Bublick, David Holland, Morris Bublick and Sol N. Garland organized, owned, operated, supervised and managed the corporation; that although plaintiff took “proper proceedings” against the corporation, it was “unable to pay the amounts due plaintiff”; that the individual defendants were personally hable for the taxes due according to section 13% of the Act1 (Ill. Rev. Stat. 1971, ch. 120, par. 452½) by virtue of their wilful failure to file; and that the individual defendants were similarly liable in the amount of *87,092.35 plus interest.
*990The corporation’s answer stated that it also sold personal property for resale and that its failure to pay the balance due resulted from “an inability to make said payment or payments, together with an unwillingness of plaintiff to accept partial payments over a period of time.” The individual defendants denied that they had breached any duty under section 13M of the Act and further stated “that plaintiff has attempted to collect the taxes due from Joseph Bublick & Sons, Inc., and that Joseph Bublick & Sons, Inc. is unable to pay the amounts due.”
The following pertinent evidence was adduced at trial. .
Max L. Bublick under section 60
He was a vice-president and treasurer of the corporation from July 1969 through April 1972. It was his duty to see that the store had sufficient merchandise to continue operation. He was the only officer with authority to assemble financial information for the purpose of preparing sales tax returns. He determined what would be reported either as a sale for resale or as a sale foir use and consumption. He was unable to obtain records from his transient customer peddlers who purchased property for resale in the Maxwell Street area near the corporation’s store. He estimated “roughly about 50%” of the gross receipts represented sales for resale. The sales memoranda did not indicate whether a given transaction represented a sale for resale. However, if a sale was made to the ultimate consumer the sales slip did show that a sales tax had been charged and was paid. When he became aware that he had to keep resale numbers on sales to peddlers he began to pay taxes on 100% of his gross receipts. On June 29,1972, he admitted that *92,342.36 was due and owing to plaintiff. A *5,000 payment was subsequently paid to plaintiff. The corporation offered to give the keys to the store to plaintiff, but plaintiff declined this offer. The corporation no longer operates the store. The corporate assets were reduced to eleven or twelve thousand dollars in cash and put into a corporate account. This account has been offered to plaintiff.
When questioned by his attorney, he stated that he was in the store about one hour per week. Although he would take the receipts from the register, he never saw the sales slips. The corporation met several times with plaintiff. On one occasion the corporation offered to pay an additional *5,000 down and - *2,000 per month, but plaintiff never responded to this offer.
On redirect, he admitted plaintiff had indicated that it would accept 25 or 30 percent down and the balance in 10 or 12 months.
*991 David Holland under section 60
He was a vice-president and the secretary for the corporation. He did not have any corporate duties regarding financial data that applied to the monthly sales tax returns. He never signed any tax returns for the corporation.
Sol N. Garland under section 60
He was the assistant secretary and bookkeeper for the corporation. He signed all tax forms submitted to plaintiff. He prepared the tax forms from the figures in the cash receipts journal. Defendant directed him to insert 50% of the cash receipts total in the journal on the “total receipts from sales for that month” entry on the tax form.
When questioned by the court, he stated that at the time of the audit which was conducted by plaintiff, the corporation had no documents to corroborate any sales for resale.
Morris Bublick under section 60
He was the corporation’s president. He did not spend any time at the store nor was he aware of how the tax forms were prepared.
He is a certified public accountant. He supervised and prepared two documents which show the cash position of the corporation during the 4/2-year period preceding April 30, 1974.
On November 25, 1974, the trial court entered two judgments to supplement its September 25, 1974, judgment of liability against the corporation. In the first, the trial court adjudged that plaintiff take nothing from defendants Morris Bublick, David Holland and Sol N. Garland. In the second, the trial court found the September 25, 1974, judgment remained unsatisfied, the corporation was unable to pay the judgment, and defendant Max Bublick had the responsibility for filing and payment of the tax. Based upon these specific findings, the trial court adjudged defendant liable in the amount of *107,932.73.
Defendant contends that the evidence did not establish that plaintiff instituted proper proceedings for the collection of unpaid taxes against the corporation before proceeding against the individual defendants. Section 13/2 of the Retailers’ Occupation Tax Act provides that the corporate officer will be personally liable only “in the event that after proper proceedings for the collection of such amounts, as provided in said Act, such corporation is unable to pay such amounts to the department.” (Ill. Rev. Stat. 1971, ch. 120, par. 452½.) The precise issue of what constitutes proper proceedings for collection appears to be one of *992first impression. However, section 5 of the Act (Ill. Rev. Stat. 1971, ch. 120, par. 444) gives plaintiff the right to bring suit to recover unpaid taxes and further provides that “[execution shall issue upon such judgment upon the request of the Department, and all laws applicable to sales on execution shall be applicable to sales made under such judgments.” For this reason, actions for recovery of retailers’ occupation taxes have been characterized as common-law actions of debt. Department of Revenue v. Joch, 410 Ill. 308, 102 N.E.2d 155; 31 Ill. L. & Pr. Retailers’ Occupation Tax §36 (1957).
In the instant case, the evidence at trial fails to establish that plaintiff pursued even one of the myriad of summary remedies which are available to a judgment creditor before proceeding against the corporate officers under section 13M. In fact, plaintiff proceeded simultaneously by its two-count complaint against both the corporation and the officers. Even if we consider that the judgment against the corporation preceded the judgment against defendant by two months, plaintiff still failed to produce any evidence that it had employed any form of execution on the initial judgment prior to the entry of the later judgment. Since the judgment of personal liability was not entered after proper proceedings for the collection of the taxes from the corporation, we believe that the trial court erred and the judgment must be reversed.
We will not speculate based upon this record whether the corporation’s financial structure would have been able to adequately satisfy its liability to plaintiff at the time the corporation admitted its liability a period of some two years and three months before the initial judgment was entered. We do note, however, although there was a substantial amount of money in a corporate bank account which could have been applied to the corporate indebtedness, plaintiff failed to pursue its rights to that account at the time of defendant’s trial.
Finally, plaintiff has argued on oral argument that defendant admitted in his answer that proper proceedings were followed. While defendant did admit that the corporation was unable to pay the amount due, he did not respond to the allegation of proper proceedings. Generally, allegations not specifically denied by defendant are deemed admitted. (Ill. Rev. Stat. 1975, ch. 110, par. 40.) It is well established, however, that legal conclusions are not admitted by the failure to plead thereto. (People ex rel. Lacanski v. Backes, 19 Ill. 2d 541, 169 N.E.2d 80; Serletic v. Jeromell, 324 Ill. App. 233, 57 N.E.2d 896.) Since the determination of what constitutes a proper proceeding under the Act is clearly a legal conclusion, we believe that plaintiff’s argument cannot be sustained.
In light of our finding that plaintiff failed to employ the proper proceedings for collection against the corporation, we need not reach *993defendant’s other contention in this opinion. The judgment of the circuit court is reversed.
