I've earned a significant amount of 1099 income (self-employed) in the first quarter of 2014 (through 3/31/2014), but as of now, I have no idea what (if anything) I will earn for the rest of the year. How should I handle this situation to avoid penalties? I know you can use the "annualized method" and pay taxes on what you earned per quarter. Under this method, if I earn $0 in the second quarter, would I just not send in a voucher? What if I don't earn any additional income until the 4th quarter? Would I just send no voucher for Q2 and Q3?
Thank you for any tips you may have.
