delivered the opinion of the court:
This case reaches us for resolution of certified questions pursuant to Supreme Court Rule 308 (155 111. 2d R. 308). Plaintiff, Inphoto Surveillance, Inc., filed a complaint against defendant, Crowe, Chizek and Company, LLR alleging that defendant negligently rendered accounting advice regаrding plaintiffs liability for sales taxes in the State of New York. Plaintiff alleged that as a result of the negligent advice it failed to collect sales tax from its customers in New York and incurred a substantial tax burden as a result. Defendant moved to dismiss the complaint alleging that thе cause of action was barred by the statute of repose contained in section 13 — 214.2(b) of the Limitations Act (735 ILCS 5/13 — 214.2(b) (West 2000)). The trial court denied defendant’s motion to dismiss and certified the following questions for interlocutory review:
“Although the exception to the acсountant’s statute of repose provided for in 735 ILCS 5/13 — 214.2(b) refers to ‘income tax assessments,’ should § 13 — 214.2 be construed to permit an action under the circumstances of this case, based on an assessment of sales taxes?”
and
“Although the exception to the accоuntant’s statute of repose provided for in 735 ILCS 5/13 — 214.2(b) refers to extending the time to file an action against the accountant ‘who prepared the tax return,’ should § 13 — 214.2 be construed so as to permit an action, under the circumstances of this case, against an accountant which advised its client (who followed the advice) that a tax return did not have to be prepared or filed?”
We granted leave to appeal these questions.
BACKGROUND
Plaintiff’s complaint alleged the following. Plaintiff provides surveillance services in Illinois and other states for the insurance industry. Defendant provided accounting services and advice to plaintiff. In 1992 plaintiff began providing surveillance services to customers in New York and asked defendant whether it was required to collect sales tax from its clients and file sales tax returns with the State of New York. Defendant advised plaintiff that it did not need to register as a sales tax vendor or collect sales taxes. In reliance on defendant’s advice, plaintiff did not collect sales taxes or remit sales taxes to New York.
In 1999 plaintiff entered into a voluntary disclosure рrogram with the New York State Department of Taxation. As a condition of acceptance into the program, plaintiff paid approximately $500,000 assessed as unpaid sales tax. Plaintiff alleged that defendant’s advice regarding the payment of sales taxes to New York was wrong and that it was at all times required to collect and pay sales taxes. Plaintiff alleged that defendant’s advice breached the standard of care and that it was injured because absent the erroneous tax advice it would have collected the required sales taxes from its customers. Plaintiffs complaint contained a second count entitled “Implied Indemnity.” Plaintiff alleged that because it relied on defendant’s advice regarding the collection of sales taxes, defendant was required to indemnify it for the back taxes it paid to the State of New York.
Defendant moved to dismiss plaintiffs complaint pursuant to section 2 — 615 of the Code of Civil Procedure (735 ILCS 5/2 — 615 (West 2000)). Defendant alleged that the complaint was barred by the two-year statute of limitations contained in section 13 — 214.2(a) of the Limitations Act. Defendant alternatively alleged that the complaint was barred by the five-year statute of repose contained in section 13— 214.2(b) of the Limitations Act. On July 12, 2002, the trial court denied defendant’s motion to dismiss “for the rеasons stated in open court.” However, there is no report of proceedings or bystander’s report in the record which reflects the reasons given by the trial court for its denial of the motion to dismiss. Defendant subsequently moved to reconsider the trial cоurt’s ruling or in the alternative certify the question for immediate interlocutory appeal. The trial court denied defendant’s motion to reconsider and granted its motion to certify the question for appeal. In its written order the trial court held that it “would make no sеnse to limit the exception to income, as opposed to sales, tax assessment.” The trial court also certified the two questions for appeal set forth above. We subsequently granted defendant’s petition for leave to appeal.
ANALYSIS
Our disрosition of this appeal depends on an interpretation of the statute of repose applicable to accountants. Section 13 — 214.2 of the Limitations Act provides, in pertinent part:
“(a) Actions based upon tort, contract or otherwise against any person, partnership or corporation registered pursuant to the Illinois Public Accounting Act, as amended, or any of its employees, partners, members, officers or shareholders, for an act or omission in the performance of professional services shall be commenced within 2 years from the time the person bringing an action knew or should reasonably have known of such act or omission.
(b) In no event shall such action be brought more than 5 years after the date on which occurred thе act or omission alleged in such action to have been the cause of the injury to the person bringing such action against a public accountant. Provided, however, that in the event that an income tax assessment is made or criminal prosecution is brоught against a person, that person may bring an action against the public accountant who prepared the tax return within two years from the date of the assessment or conclusion of the prosecution.” 735 ILCS 5/13 — 214.2 (West 2000).
The interpretation of a statute is a quеstion of law, which reviewing courts resolve de novo. Advincula v. United Blood Services,
Section 13 — 214.2(b) provides both a statute of repose barring сlaims against accountants after five years and an exception to that statute of repose if “an income tax assessment or criminal prosecution” is brought. 735 ILCS 5/13 — 214.2(b) (West 2000). Plaintiff concedes that the “criminal prosecution” portion of the exception has no application in this case because it entered into a voluntary disclosure program that avoided the possibility of criminal prosecution. The sole question, therefore, is whether we should construe the phrase “income tax assessmеnt” to include “sales tax assessment.” We find that there is nothing ambiguous about the phrase “income tax assessment.” Further we find nothing within the language of the statute to suggest that the legislature intended the exception to apply to sales tax assessments. If the legislature hаd intended this section to apply to sales tax assessments, it could have easily included that phrase in the statute. Similarly, if the legislature had intended this section to apply to tax assessments in general, it could have easily omitted the word “income” from the phrase “income tax assessment.” If the legislature had done so, we would be forced to conclude the exception applies to all types of taxes, income tax, sales tax, real estate tax, excise tax, or any other tax. However, the lеgislature unambiguously limited the exception to “income tax assessments.” We believe that construing the statute in the manner the trial court did impermissibly creates an exception that the legislature did not intend. Accordingly, we conclude that the exception to the statute of repose contained in section 13 — 214.2(b) cannot be construed to apply to sales tax assessments.
Plaintiff argues that a cause of action for accounting malpractice does not accrue until an income tax assessment is made. See Bronstein v. Kalcheim & Kalcheim, Ltd.,
We find several flaws in plaintiffs argument. First, we only apply a consideration of the intent of the legislature to construe a statute if the language of the statue is ambiguous. See Poullette v. Silverstein,
We note that although plaintiff bases its arguments on the similarity between sales tax and income tax assessments, plaintiff has made no constitutional challenge to the statute. Plaintiff does not argue that by making a distinction between income tax and other types of tax assessments the legislature violated either due process or equal protection.
We conclude that the exception to the statute of repose cannot be construed to apply to sales tax аssessments. Accordingly, we answer the trial court’s first certified question in the negative. Our disposition of this question obviates the need to address the trial court’s second certified question. If the exception does not apply to sales tax assessments, there is no nеed to determine whether the failure to prepare a sales tax return is the equivalent of preparing a faulty return. Plaintiff raised an additional argument on appeal related to whether its “implied indemnity” count was subject to the statute of repose. However, the trial court did not address this issue below and did not certify a question regarding that issue. Therefore, we decline to address plaintiffs arguments on appeal. However, because this argument presents a potential alternative basis for denying defendant’s motion to dismiss, we will not reverse the order of trial court outright. Instead, we vacate the order of the trial court denying defendant’s motion to dismiss. See Kleen v. Homak Manufacturing Co.,
Certified question answered, order vacated, and cause remanded.
