I live and work in California. I made $8,000 in about a month in 2008 as a freelance designer before my company hired me full time on their payroll, as an employee. How do I pay taxes on the $8,000 I made while freelancing? Do I have to send it somewhere or can I pay when I pay my normal 2008 taxes? I have heard as low as 30% and as high as 50%... The company I work for is currently withholding the "normal" taxes for me. Any help would be much appreciated.
