Semi-weekly depositor
(3) Semi-weekly depositor. An agricultural employer is a semi-weekly depositor of Form 943 taxes for a calendar year if the amount of Form 943 taxes accumulated in the lookback period (as defined in paragraph (g)(4) of this section) exceeds $50,000. (4) Lookback period(i) In general. For purposes of this paragraph (g), the lookback period for Form 943 taxes is the second calendar year preceding the current calendar year. For example, the lookback period for calendar year 1993 is calendar year 1991. New employers shall be treated as having employment tax liabilities of zero for any lookback period before the date the employer started or acquired its business. (ii) Adjustments and Claims for Refund. The employment tax liability reported on the original return for the return period is the amount taken into account in determining whether the amount of Form 943 taxes accumulated in the lookback period exceeds $50,000. Any amounts reported on adjusted returns or claims for refund pursuant to sections 6205, 6402, 6413 and 6414 filed after the due date of the original return are not taken into account when determining the amount of Form 943 taxes accumulated in the lookback period. However, prior period adjustments reported on Form 943 for 2008 and earlier years are taken into account in determining the employment tax liability for the return period in which the adjustments are reported. (5) The following example illustrates the provisions of this section.
