Thank you both for your replies. I saw this article - <a rel="nofollow" target="_blank" href="
http://smallbusiness.findlaw.com/incorporation-and-legal-structures/your-sole-proprietorship-and-you...> - that indicated there could be employment taxes owed for the work your spouse does if you are not careful about the nature of the work.
"As a business owner, you will typically owe employment taxes and have to withhold a certain portion of an employee's paycheck for tax purposes. If you plan on having your spouse occasionally volunteer for your business, you need to be extremely careful about what you allow them to do and how often they volunteer.
For example, if your spouse does any sort of advertising, contact with the public or signing of documents he or she may be holding him or herself out to the public as a co-owner of the business in the eyes of the IRS. If that happens, the IRS will hit you with back taxes and penalties..."
Another article talked about "frequent and regular" involvement being a trigger.
My wife is starting a photography business and is starting out as a sole proprietorship (don't want to delve into all the pros and cons of that in this thread). I am helping on the business side but want to make sure I don't cause any tax problems for us later. So I am trying to find the actually IRS guidelines that address this.
