2012 IL App (1st) 113053
Ill. App. Ct.2012Background
- Ameritech merged with SBC Teleholdings in 1999, causing dual Illinois returns for pre- and postmerger periods.
- Ameritech elected rateable allocation of its 1999 federal income between pre- and postmerger periods, with specific day-based fractions.
- Illinois returns used apportionment under section 304(h)(2); Department altered premerger apportionment using section 304(h)(1).
- Department corrected the premerger return via a mathematical error correction without a notice of deficiency, reducing Ameritech’s refund.
- Circuit court reversed the Department’s decision, concluding the mathematical error procedure was improperly used; Department appeals.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Was the mathematical error procedure proper? | Ameritech: improper, require deficiency process due to substantive tax law issues. | Department: proper mathematical error correction; premerger factor was facially defective. | No; the Department improperly used mathematical error procedure. |
| Does offset authority under 909(a) apply or were arguments forfeited? | Ameritech could argue offset; Department forfeited arguments by not raising below. | Department could offset overpayments; Ameritech lacked standing after procedural lapses. | Department forfeited 909(a) argument; not concluded here. |
| Should the apportionment issue have been resolved via deficiency procedures? | Substantive tax-law interpretation; required thorough analysis, not math error. | Mathematical error suffices to correct the premerger return. | Yes; substantive apportionment questions should use deficiency procedures. |
