Form 943 reports federal income tax withheld and Social Security and Medicare tax for agricultural employees. It is annual rather than quarterly, which is the main practical difference from Form 941. An employer with both farm and non-farm employees files both: 943 for the farm payroll and 941 for the rest. The tests that decide whether farm wages are subject to employment tax at all are their own - based on cash wages paid to a worker in the year, and on total farm labour expenditure.

Allocation Schedule for Aggregate Form 943 Filers
Filed by an aggregate filer to allocate the return across the clients it files for.
Whether you deposit monthly or semiweekly depends on your lookback period, not on this form. Publication 15 (Circular E) sets the rule, and it is worth checking each year - the schedule can change when your liability does.
IRS Publication 15Yes, and it is common. Farm payroll goes on 943 annually; any non-farm employees go on 941 quarterly. The two do not overlap.
