How do I account for employee gifts in payroll?

[bigforksugar]

I like to give my employees gift cards or cash as bonuses for hard work, but I know I have to pay taxes on them to write them off.  How do I account for off-paycheck employee gifts through payroll?  Most of them are on direct deposit, so I can't do a manual adjustment on their check which I used to do.  Thank you.

There is a column in Square Payroll for Additional.  The hover help at the top of the column indicates that this is for bonuses and other additional amounts for each employee.  This is where I have placed these kind of gift cards and bonuses whenever we offer them to team members for job well done, etc.
