Let me rephrase just to make sure that I am indeed understanding everything - quarterly tax aka estimated tax (the 1040-ES) can be submitted by Jan 15th but I can wait and combine it with the 1040 (my income tax return) and I am in the clear if that is submitted by Feb 1st. 1099 is due by March 31st.
BUT (and someone let me know if I am correct in saying this) since I didn't file taxes for the year 2014 I am exempt from filing estimated tax...which would then mean that I have to submit my 1040 by April 18th of this year. I am going off by the "Who Does Not Have To Pay Estimated Tax" on this page:
