If you are not sure that the wages that you pay to a farmworker during the year will be taxable, you may either deduct the tax when you make the payments or wait until the $2,500 test or the $150 test explained in

taxmap/pubs/p80-007.htm#en_us_publink1000233958If you pay your employee's social security and Medicare taxes without deducting them from the employee's pay, you must include the amount of the payments in the employee's wages for social security and Medicare taxes. This increase in the employee's wage payment for your payment of the employee's social security and Medicare taxes is also subject to employee social security and Medicare taxes. This again increases the amount of the additional taxes that you must
pay.
