Rev. Rul. 56-39

The tax on admissions, imposed by section 4231 of the Internal Revenue Code of 1954, applies to an admission charge in excess of 50 cents even though the excess is only a fraction of a cent. However, where an admission charge is 50 cents and the computation of a state tax thereon results in a fractional part of a cent, which necessitates the collection of an amount in excess of the state tax actually due, the Federal tax on admissions does not apply provided such excess amount is shown as state tax. In such case, the excess amount collected is not considered to be an additional charge for admission.
