In Chapter 22, I mentioned the advantages of incorporation as a nonprofit to make yourself eligible for grants. Incorporation as a for-profit company might make sense for your grant-writing business as well. Different forms of corporate structures offer advantages and disadvantages, including possibly insulating your personal assets in case of a lawsuit or bankruptcy. For most grant-writing freelancers, incorporation isn’t necessary, but you should talk this over with your tax and legal advisers.
Whether or not you decide to incorporate, you might want to open a separate checking account and have a separate credit card to keep your personal and business finances separate.
