Every year New Mexico publishes a list of approved fed/state software developers who have demonstrated successful transmission of New Mexico personal income tax returns through the fed/state program. Software developers require annual approval. The list of approved software companies appears on or around the beginning of the year. If you are looking for a software solution before release of the approval list for the tax year in which you wish to e-file personal income tax returns, ask the software company whether it plans to support New Mexico state personal income tax returns. To view the list of approved companies, go to Software Developers.
