{"data":{"id":"us/26-cfr-1.1374-5","jurisdiction":"us","citation":"26 CFR 1.1374-5","heading":"-5 Loss carryforwards.","body":"(a) In general. The loss carryforwards allowed as deductions against net recognized built-in gain under section 1374(b)(2) are allowed only to the extent their use is allowed under the rules applying to C corporations. Any other loss carryforwards, such as charitable contribution carryforwards under section 170(d)(2), are not allowed as deductions against net recognized built-in gain.\n(b) Example. The rules of this section are illustrated by the following example.\nExample: Section 382 limitation.\nX is a C corporation that has an ownership change under section 382(g)(1) on January 1, 1994. On that date, X has a fair market value of $500,000, NOL carryforwards of $400,000, and a net unrealized built-in gain under section 382(h)(3)(A) of $0. Assume X's section 382 limitation under section 382(b)(1) is $40,000. X elects to become an S corporation on January 1, 1998. On that date, X has NOL carryforwards of $240,000 (having used $160,000 of its pre-change net operating losses in its 4 preceding taxable years) and a section 1374 net unrealized built-in gain of $250,000. In 1998, X has net recognized built-in gain of $100,000. X may use $40,000 of its NOL carryforwards as a deduction against its $100,000 net recognized built-in gain, because X's section 382 limitation is $40,000.","path":["Title 26—Internal Revenue","CHAPTER I—INTERNAL REVENUE SERVICE, DEPARTMENT OF THE TREASURY","SUBCHAPTER A—INCOME TAX","PART 1—INCOME TAXES"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-26.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:25:11Z","sha256":"1d2fb81c3398a012ac5e8b1d1be5bcc810167bca7ec5ac93ba1761986a6a5505","source_id":"us-cfr","stale":true,"prev":"us/26-cfr-1.1374-4","next":"us/26-cfr-1.1374-6"},"notice":"GroundRules: Original legal text.
