I have created many LLC's in my time. It's definitely worth the money to CYA (Cover Your Assets). For LLC's its not a matter of extra taxes, as the income passes through to the principals of the company, Inc's its a different story. Best advice is have an attorney draft your LLC or Inc. etc, after you have consulted with your accountant to make sure which option is the best for you personally. Make sure to ask tons of questions during the process and then after you file your first LLC with professional guidance you can now start creating companies yourself.
