Anti-trafficking rules.
Anti-trafficking rules. If section 382, 383, or 384 would have applied to limit the use of a corporation's recognized built-in loss or section 1374 attributes at the beginning of the first day of the recognition period if the corporation had remained a C corporation, these sections apply to limit their use in determining the S corporation's pre-limitation amount, taxable income limitation, net unrealized built-in gain limitation, deductions against net recognized built-in gain, and credits against the section 1374 tax.
