I work at a full time job that provides about 90 - 95% of my income, and then put in about 3 hours a week working as an independent contractor. For that I get a check with no taxes etc . . . taken out.
What do I have to do come tax time to account for that income -- just add it up, and write it on a line somewhere? Or do I have to fill out other forms?
Also, I usually get the check about a month after I do the work, so do I count the money I earned in December and will receive in January as 2008 or 2009 income?
