26 U.S.C. § 194A — Contributions to employer liability trusts

(a) Allowance of deduction. An employer may deduct, for the tax year, the amount it contributes to a trust (described in section 501(c)(22), which relates to a withdrawal-liability payment fund) that meets the requirements of section 4223(h) of the Employee Retirement Income Security Act of 1974 — but only the part properly counted for that tax year. (b) Allocation to taxable year. If a contribution covers a period spanning more than one tax year, the Secretary's regulations determine how much of it counts toward each tax year in that period. (c) Disallowance of deduction. No deduction is allowed for a contribution that doesn't relate to any specific period of time.
