Your legal options are to hire someone as an employee or as an independent contractor.
If you hire someone as an employee, you need to fill out a bunch of employment forms and when you pay that person you need to withhold taxes for them. Insurance requirements for agricultural employees vary by state so you may or may not need to pay for workman’s comp insurance. You would likely want some kind of insurance to cover you as an employer, though.
If you hire someone as an independent contractor, you keep track of what you pay them, and then at the end of the year, you provide them with a 1099 form. Independent contractors are expected to pay their own taxes, so you don’t have to withhold any money.
To many people, pay as an independent contractor seems like the easiest way to go. But, you can get it a lot of trouble over this if there is an issue and your worker is determined to actually be an employee and not an independent contractor. There can be some serious financial penalties involved. An accountant can help you determine if you can legally pay someone as an IC.
One important factor to consider is that no matter how you hire someone, you are exposed to liability risk. It’s easy for a barn worker to get seriously injured–kicked, bitten, stepped on, etc. Heck, even just a “minor” injury can easily rack up $10,000 or more in medical bills once someone goes to the hospital or needs “minor” surgery. So whatever method you choose for hiring someone, talk with your insurance agent about the “what-ifs” and make sure you are adequately covered.
