Final answer:
To determine the exemption for registering as an IA, the number of clients in the last 12 months is a factor but not the sole determinant. Other factors such as nature of services, relationship with clients, and state laws should also be considered.
Step-by-step explanation:
To determine how many clients an Independent Contractor (IA) could have in the last 12 months to be exempt from registering, it depends on the specific requirements of the jurisdiction.
In the United States, for example, the Internal Revenue Service (IRS) considers an IA to be exempt from self-employment tax if they had fewer than 400 clients in the last year.
However, it's important to note that the number of clients alone may not be the only factor to determine exemption. Other factors such as the nature and duration of the services provided, the relationship between the IA and the clients, and any applicable state laws should be taken into account.
It is always recommended to consult with a tax professional or legal advisor to ensure compliance with the specific regulations of your jurisdiction.
