Understanding Your CP137 Notice

Your deposit requirements for Form 943 for next year may be different, based on your Form 943 tax from last year. CP 137 gives your deposit requirements for next year.

What you need 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 taxes for wages accumulated during a month by the 15th of the following month.
  • If your tax liability for last year was over $50,000, you are a semi-weekly depositor. Semi-weekly depositors must deposit taxes for wages paid on Saturday, Sunday, Monday, or Tuesday by the following Friday. Taxes for wages paid on Wednesday, Thursday, or Friday are due the following Wednesday.
  • If the tax amount we used to determine your tax requirement differs from your tax records, then you must determine the appropriate deposit schedule.
  • If the tax amount we used is zero, then we have no record of receiving last year’s Form 943. Please file Form 943 as soon as possible. Do not file Form 943 if you were not required to file Form 943.

    Answers to Common Questions

    How do I show my payments when I file Form 941?
    We have a record of your payments. Do not show your payments. Show the tax liabilities.

    How do I show the tax liabilities?
    If you are a monthly depositor, enter the payroll tax due for each month in the monthly summary of federal tax liability. If you are a semi-weekly depositor, use Form 943-A to enter the tax due for each date you paid your employees.

    What do I do if the tax liability on the notice is incorrect?
    The tax liability on the notice includes only the tax liability on your original Form 943 for last year. Don’t include amended returns. Determine your deposit requirements based on the correct original tax liability for last year.

    Do I have to file electronically?
    You must pay all deposits after December 31, 2010 electronically, unless your tax is less than $2,500. If your tax for the year is less than $2,500, you can pay with Form 943.

    What if my accumulated tax liability reaches $100,000?
    If your liability reaches $100,000, you must deposit the next business day. After that, you immediately become a semi-weekly depositor for the rest of the year and the next year.
