What the IRS says to do

If your tax liability for last year was $50,000 or less, you are a monthly depositor next year. Monthly depositors must deposit withholding taxes on nonpayroll payments paid during a month by the 15th day of the following month. If your tax liability for last year was over $50,000, you are a semi-weekly depositor next year. Semi-weekly depositors must deposit withholding taxes on nonpayroll payments paid on Saturday, Sunday, Monday, or Tuesday by the following Friday. Taxes on payments paid on Wednesday, Thursday, or Friday are due the following Wednesday. Check your records to determine if they agree with the liability shown on CP137B. If the amount we used differs from your tax records, then you must determine and follow the appropriate deposit schedule. If the tax amount we used is zero, then we have no record of receiving last year's Form 945. Please file Form 945 as soon as possible.
