What is efile.technology?
efile.technology is a planned service, not a live one. The idea is MCP tools and a REST API so that software and AI agents can prepare and transmit U.S. federal tax returns to the IRS, starting with employment tax. Today the site is an information page and an early-access waitlist. The IRS has accepted Terragroupe, LLC as an e-file provider (Electronic Return Originator, Transmitter and Software Developer). We are preparing for IRS testing and have not been approved to transmit returns, so we cannot file returns for anyone yet. Acceptance as a provider is not IRS approval or endorsement of our software. We are not affiliated with, endorsed by, or acting on behalf of the IRS.
Current status
- The filing service is not live. There is nothing to sign up for except the waitlist.
- The IRS has accepted Terragroupe, LLC as an e-file provider (Electronic Return Originator, Transmitter and Software Developer). We are preparing for IRS testing and have not been approved to transmit returns, so we cannot file returns for anyone yet. Acceptance as a provider is not IRS approval or endorsement of our software. We are not affiliated with, endorsed by, or acting on behalf of the IRS.
- No pricing exists yet. Pricing will be announced at launch, if there is a launch.
- We do not collect tax returns or taxpayer data through this site.
What we plan to build
- MCP tools and a REST API. A programmatic way for AI agents, payroll systems, accounting platforms and firms to prepare and transmit returns.
- Validation before filing. Pre-submission checks against published IRS business rules so common errors are caught early.
- Employment tax first. Forms 941 and 944 first, with the business extension Form 7004 to follow; more forms later. These are plans, not live. Timelines depend on IRS approvals and software testing.
Who it is for
Developers of payroll and accounting software, builders of AI agents, and accounting firms and platforms that file employment tax returns for clients.
What the IRS requires before software can transmit returns
Sending returns to the IRS electronically requires IRS acceptance as a provider and software testing. We explain the steps, with links to the IRS pages we read, in How software can e-file Form 941 and what the IRS requires. Related: why AI agents that prepare returns still need an IRS provider and a checklist for IRS-facing MCP tools.
