What address do I send my 1099 for the IRS?
If you receive a 1099, file your taxes and follow the instructions for filing your taxes in a standard tax software. If you are issuing 1099 to your vendors instructions are on the 1099s as to where you should file your 1099s. Along with the 1099s, you should file a 1096 (a summary of the 1099s). The 1096 has mailing instructions.
