The penalty for the late filing of Form W-3 depends on the size of the business and the duration of the delay. Here are the general guidelines: 1. Small Businesses: For small businesses (with an average of 250 or fewer employees in the previous year), the penalty for filing Form W-3 late is $50 per return if filed no later than 30 days after the due date. If filed more than 30 days after the due date but before August 1st, the penalty increases to $110 per return. If filed after August 1st, the penalty further increases to $270 per return. 2. Large Businesses: For larger businesses (with more than 250 employees on average), the penalty for late filing of Form W-3 is higher. If filed no later than 30 days after the due date, the penalty is $50 per return. If filed after 30 days but before August 1st, the penalty increases to $270 per return. If filed after August 1st, the penalty further increases to $540 per return. It is important to note that these penalties apply separately for each individual Form W-3 that is filed late. Additionally, if there is reasonable cause for the delay and the late filing is not a result of willful neglect, the penalties may be reduced or waived.
