last year peter $($EA$)$ provided full bookkeeping services to several businesses clients as a way to supplement his income during the off season. one such client received a letter from the IRS requesting payment of payroll taxes from the second and third quarters of the year. peter checked his records and found that although he had filed the correct $941$ form with the IRS and collected the withholding funds, he had forgotten to send these funds to the IRS. what penalty, if any, may peter be subject to because of his omission under Circular $230?$
