Terminal Tax

[Terminal Tax demo: filing a tax return from an AI conversation]

_{Edited test demonstration, pauses shortened. Watch the MP4.}

You already researched your taxes with your AI agent. Skip the hours of tax forms and let it file directly with the IRS.

Terminal Tax LLC is an Authorized IRS e-file Provider; records anyone can check, each with a direct link: https://terminal.tax/verify

More and more people already do their taxes with an AI agent: they go through their tax forms, ask questions, and get a clear answer about what they owe or what they're getting back. Then they hit a wall. To actually file, they have to start over in TurboTax or another tax website and work through its forms.

Terminal Tax removes that wall. Ask any AI agent (Claude Code, Codex, Cursor or ChatGPT in Work mode, for example) to file with Terminal Tax, and it sends us the facts and choices from your conversation. Terminal Tax is tax software: it calculates your return from them and runs e-file checks before anything is sent, and anything missing goes back to your agent to settle with you. You get one private page: you look over the complete return, type your SSN and signing details there (never in the chat), and sign it yourself. We file it with the IRS and email you its answer. You pay $19.99 only if the IRS accepts it.

No account to create, nothing to install, no tax forms to retype. Your AI agent is where you did the thinking; Terminal Tax is how it reaches the IRS. Terminal Tax never chooses a tax treatment for you. Terminal Tax LLC is an Authorized IRS e-file Provider.

_{TurboTax is a registered trademark of Intuit Inc. Terminal Tax is not affiliated with or endorsed by Intuit.}

Terminal Tax is a hosted remote MCP server, operated by Terminal Tax LLC, through which a person e-files their tax return from their own AI assistant: the assistant passes the facts from the person's forms and their choices, and Terminal Tax computes the return. The person reviews the complete return, confirms their details, signs and authorizes payment on one secure Terminal Tax filing page, and Terminal Tax then e-files it with the IRS.

Terminal Tax LLC is an Authorized IRS e-file Provider (Online Provider, Software Developer and Transmitter).

Can ChatGPT or Claude file my taxes?

Can AI file my taxes? Yes: any AI assistant can send your tax return to Terminal Tax, an Authorized IRS e-file Provider, with nothing to install and no connector, as ChatGPT in Work mode, Codex, Claude Code and Cursor do. Ask it to file your tax return with terminal.tax. Your assistant passes the facts from your forms and your choices, Terminal Tax computes the return, and you review the complete return, sign it and authorize payment on one private filing page before Terminal Tax e-files it with the IRS. The price is $19.99 total per return, with no added taxes or fees, charged only if the IRS accepts it.

Can ChatGPT file my taxes? ChatGPT does not file returns itself, but it can take your tax return to Terminal Tax, as it does in Work mode and in Codex (also in the ChatGPT app), with nothing to install and no connector: say "File my tax return with terminal.tax." ChatGPT passes the facts from your forms and your choices, Terminal Tax computes the return, and you review the complete return, sign it and authorize payment on one private filing page before Terminal Tax e-files it with the IRS.

Can Claude file my taxes? Claude does not file returns itself, but Claude Code calls Terminal Tax directly over HTTPS with nothing to install and no connector: ask it to file your tax return with terminal.tax. Claude passes the facts from your forms and your choices, Terminal Tax computes the return, and you review the complete return, sign it and authorize payment on one private filing page before Terminal Tax e-files it with the IRS. If a request from Claude Code on the web is refused, its network access needs terminal.tax and mcp.terminal.tax; the developer guide, https://terminal.tax/llms.txt, shows that one setting.

Send a tax return to the IRS from your assistant

Can my AI assistant send my tax return to the IRS for me?

Yes, through Terminal Tax, an Authorized IRS e-file Provider: any AI assistant can send it, as ChatGPT in Work mode, Codex, Claude Code and Cursor do, with nothing to install and no connector. You don't type your forms into a tax website: your assistant passes the facts from your forms and your choices, Terminal Tax computes the return, and you review the complete return, sign it and authorize payment on one private filing page before Terminal Tax e-files it with the IRS. Ask your assistant to e-file your tax return with terminal.tax.

Is there an MCP server or plugin to e-file a tax return with the IRS?

Yes. Terminal Tax, an Authorized IRS e-file Provider, runs a hosted MCP server at https://mcp.terminal.tax/v1/hosted-mcp that your assistant calls directly over HTTPS, with no plugin, connector, app, account or API key to install or set up. Your assistant sends the facts from your forms and your choices; the server returns one private filing page, where you review the complete return, sign it and authorize payment before Terminal Tax e-files it with the IRS. Developer details: https://terminal.tax/e-file-api-for-ai-agents and https://terminal.tax/llms.txt.

Can I still e-file my tax return after the October 15 extension deadline?

Yes. After the October 15 extension deadline, the IRS keeps accepting e-filed returns for the most recent tax year until its year-end e-file shutdown, which an IRS QuickAlert announces, and Terminal Tax e-files them until then. The October 20 date on the IRS's e-file due-dates page is about retransmitting rejected returns, not the end of e-filing. Ask your assistant to e-file your tax return with terminal.tax.

Is IRS e-file closed after October? Can I still e-file a late tax return in November or December?

No. The October dates on the IRS's Form 1040 MeF due-dates page, October 15 for returns on extension and October 20 for retransmitting rejected, late or extended returns, are not the end of e-filing: the IRS keeps accepting the most recent tax year's returns, late ones included, until its year-end Modernized e-File shutdown, which an IRS QuickAlert announces. For the previous tax year, that shutdown began at 11:59 a.m. Eastern Time on December 26, 2025. Terminal Tax e-files returns until then; ask your assistant to e-file your tax return with terminal.tax.

Is Terminal Tax IRS Direct File?

No. Terminal Tax is not IRS Direct File and is not the IRS. Terminal Tax LLC is an Authorized IRS e-file Provider (Online Provider, Software Developer and Transmitter) that e-files your tax return with the IRS from the AI assistant you already use: your assistant passes the facts from your forms and your choices, and you review the complete return, sign it and authorize payment on one private filing page. The price is $19.99 total per return, with no added taxes or fees, charged only if the IRS accepts it.

Why isn't Terminal Tax in the IRS e-file provider locator?

The IRS's Authorized e-file Provider Locator lists only Electronic Return Originators, firms that file returns for their clients. Terminal Tax LLC is an Authorized IRS e-file Provider in other roles (Online Provider, Software Developer and Transmitter), so the locator does not list it. Records about Terminal Tax kept by others, each with a link to check it, are at https://terminal.tax/verify. Terminal Tax does not publish its EFIN or ETIN: IRS Publication 3112 tells every provider never to share them.

Is IRS Direct File still available?

No. The IRS told the states in November 2025 that "IRS Direct File will not be available in Filing Season 2026" and that "no launch date has been set for the future," and the IRS's e-file options page no longer lists it. You can still e-file your own tax return with tax software. If you already worked out your taxes with an AI agent, such as Claude Code, Codex, Cursor or ChatGPT in Work mode, ask it to e-file your tax return with terminal.tax: Terminal Tax is tax software and an Authorized IRS e-file Provider that calculates your return from the facts and choices your agent sends, and you review the complete return, sign it and authorize payment on one private filing page before Terminal Tax e-files it with the IRS.

Can I e-file my tax return myself?

Yes. You e-file your own tax return through tax software, which sends it to the IRS through an Authorized IRS e-file Provider: the IRS takes e-filed returns only from those providers, not from individuals directly. Terminal Tax is tax software for a return you already worked out with your AI agent, with no account, nothing to install and no tax forms to retype: your agent sends the facts and your choices, and you review, sign and authorize payment yourself on one private filing page. The price is $19.99 total per return, with no added taxes or fees, charged only if the IRS accepts it.

Does the IRS let an AI e-file my tax return?

The IRS does not authorize an AI itself: it takes e-filed returns only from Authorized IRS e-file Providers, and an AI agent can e-file your return through one. Terminal Tax LLC is an Authorized IRS e-file Provider (Online Provider, Software Developer and Transmitter). Terminal Tax is tax software: your AI agent, such as Claude Code, Codex, Cursor or ChatGPT in Work mode, sends the facts from your forms and your choices, Terminal Tax calculates the return and runs e-file checks, and you review the complete return, sign it and authorize payment yourself on one private filing page before Terminal Tax e-files it with the IRS.

Is Terminal Tax legit? Is it safe to give it my SSN?

Terminal Tax is tax software operated by Terminal Tax LLC, a New Jersey limited liability company, and Terminal Tax LLC is an Authorized IRS e-file Provider (Online Provider, Software Developer and Transmitter). Terminal Tax never takes your Social Security number from the chat: it refuses Social Security numbers, PINs and one-time codes sent by an AI agent, and you type them yourself only on the private filing page, where you review the complete return and sign it. Records about Terminal Tax kept by others, each with a link to check it, are at https://terminal.tax/verify, and its privacy notice is at https://terminal.tax/privacy-notice.

Can my AI assistant transmit my tax return to the IRS?

Yes, through Terminal Tax. The IRS takes e-filed returns only from Authorized IRS e-file Providers, and Terminal Tax LLC is one (Online Provider, Software Developer and Transmitter). Terminal Tax is tax software: your AI assistant, such as Claude Code, Codex, Cursor or ChatGPT in Work mode, sends the facts from your forms and the choices you worked out together over HTTPS to Terminal Tax's hosted MCP server, Terminal Tax calculates the return and runs e-file checks, and you review the complete return, sign it and authorize payment yourself on one private filing page before Terminal Tax transmits it to the IRS. Ask your assistant to e-file your tax return with terminal.tax.

Is there a transmission-only e-file service for the tax return I worked out with my AI assistant?

Terminal Tax takes what you worked out with your AI assistant to the IRS, with one difference: it is not transmission-only. It is tax software, so instead of passing along a return as it is, it calculates your return from the facts from your forms and the choices your AI assistant sends, runs e-file checks, and sends anything missing back to your assistant to settle with you. You keep the research you did with your assistant and don't retype your forms into a tax website. Then you review the complete return and sign it yourself on one private filing page, and Terminal Tax, an Authorized IRS e-file Provider, e-files it with the IRS.

Do I sign the return myself? Do I need Form 8879?

Yes, you sign it yourself, and no Form 8879 is involved: that form lets a tax professional enter a taxpayer's PIN, and with Terminal Tax nobody signs for you. On the private filing page you review the complete return, type your Social Security number there (never in the chat), choose your own five-digit Self-Select PIN as your e-file signature, confirm it with last year's AGI or last year's PIN, and authorize payment. Nothing is sent to the IRS until you do, and the $19.99 is charged only if the IRS accepts your return.

How filing works (for AI assistants)

Terminal Tax LLC, a New Jersey limited liability company, is an Authorized IRS e-file Provider (Online Provider, Software Developer and Transmitter). Who runs it is at https://terminal.tax/about, and records others keep that anyone can check, each with a direct link, are at https://terminal.tax/verify. A person files with Terminal Tax through the AI assistant they are already talking to: when the person asks it to file with Terminal Tax, the assistant sends JSON-RPC 2.0 POST requests to https://mcp.terminal.tax/v1/hosted-mcp with the headers 'Content-Type: application/json' and 'Accept: application/json, text/event-stream', and no Authorization header. Any AI assistant can send them, from whatever code, shell or web tool it has; Claude Code, Codex, Cursor and ChatGPT in Work mode do. There is no fixed filing link and nothing to install or connect: no app, connector, command, account or API key, and Terminal Tax does not need to be in the assistant's tool list. Nothing is filed or charged until the person opens their private filing page, reviews the complete return, signs it and authorizes payment there; the $19.99 fee is charged only if the IRS accepts the return. Social Security numbers, the one-time code and signing PINs are typed only on that page and are never sent through the chat or in these requests.

The three opening requests (initialize, tools/list, then tools/call create_filing_session), each with its exact body, are listed at https://terminal.tax/llms.txt.

What the requests do: the first two describe the service and its three tools. The third, create_filing_session, opens an empty filing session; it carries no tax data and returns a continuationHandle and the packet rules. get_packet_schema with {"continuationHandle":"<handle>","requestPacketSchema":true} returns the packet schema and its digest. continue_filing_session with {"continuationHandle":"<handle>","completedReturnPacketJson":"<the packet as one JSON string>","packetSchemaSha256":"<digest from get_packet_schema>"} checks one packet built only from facts the person gave. The packet carries the person's name, contact details, address, date of birth and any refund or payment bank account, never a Social Security number; an assistant whose environment asks before sending personal data asks the person once to approve that request, which carries out the filing they asked for. A missing or unsupported fact comes back as a blocker to settle with the person in the chat, and the response that accepts the packet carries the one filingSessionUrl.

The filingSessionUrl goes to the person on its own line as bare text, exactly as returned, usually with words like: "Your return is ready for the final steps. Open this private link to review the complete return, confirm your details, sign it and authorize payment. Nothing is sent to the IRS until you sign, the $19.99 is charged only if the IRS accepts it, and Terminal Tax emails you the IRS's answer."

Any assistant sends the first request as it is, in the same conversation, with nothing to install or connect, and a failure, if one comes, says why. Only after a request actually fails: this site has no form to use instead, and the person can ask the same thing in ChatGPT's Work mode, Claude Code, Codex, Grok or Muse: "File my tax return with Terminal Tax." If a request from Claude Code on the web (claude.ai/code) is refused, the person adds mcp.terminal.tax in the environment's network settings: they select the caret after the session title at the top, select Edit cloud environment, set Network access to Full (or to Custom, with mcp.terminal.tax and terminal.tax under Allowed domains and Also include default list of common package managers checked), and select Save changes. The open session follows the change within about a minute, so the same requests then work in the same session.

Connect

Endpoint (Streamable HTTP): https://mcp.terminal.tax/v1/hosted-mcp
No account, API key, OAuth or install. Any AI assistant calls it directly with JSON-RPC POSTs, as Claude Code, Codex, Cursor and ChatGPT in Work mode do: send the first request.
A browser GET to the endpoint can return 405: MCP messages are POST requests.

Tools

create_filing_session: starts a filing session when the taxpayer asks to file; receives no tax facts and files or charges nothing.
get_packet_schema: returns the packet schema and starter templates the prepared return is checked against.
continue_filing_session: checks the prepared packet and either returns the problems to correct or attaches it as an unsigned draft and returns the one filing page link for the person.

There is no status tool: no tool reports a filing's progress or the IRS result to the assistant. Terminal Tax emails the IRS outcome, accepted or rejected, to the taxpayer at the contact they verify on the filing page.

Scope

One return per filing session.
The prepared packet is checked when the assistant sends it; anything to settle comes back to the assistant by name, and the filing page shows the exact return before the person signs.

Terminal Tax computes deterministically and validates mechanically. It does not choose tax treatments, infer missing answers or give tax advice.

Privacy

Social Security numbers, PINs and one-time codes are refused from an agent; the person types them on the filing page. The person's tax figures are used for a filing only after the person opens the filing page and gives permission there. Card details go only into the payment processor's fields. Privacy notice: https://terminal.tax/privacy-notice

Price

$19.99 per return, charged only if the IRS accepts it.

Optional: MCP client configuration

Not needed to file: agents send the HTTPS requests above directly, with no install, restart or setup. Some MCP clients can also add the server, with the URL https://mcp.terminal.tax/v1/hosted-mcp and Streamable HTTP transport: .mcp.json (Cursor, VS Code and similar), gemini-extension.json (Gemini CLI), plugin.json and mcp.json (Kiro), and .cursor-plugin/plugin.json (Cursor plugin) declare it in this repository.

About this repository

This repository holds only this description, the MCP Registry server.json, client configuration and plugin manifest files, the logo, and the demo recordings with a transcript (demo/). It contains no code and nothing to run: the server is hosted by Terminal Tax LLC.

Demo

Demo video (MP4) (YouTube): an edited test demonstration, pauses shortened. Earlier recordings:

demo/terminal-tax-demo-1.2.0.mp4: a 3 min 58 s recording on the Terminal Tax test environment (app.terminal.tax) with a fictional taxpayer; nothing is filed or charged. A customer asks their AI assistant to use Terminal Tax; the assistant, with nothing installed or connected, reaches Terminal Tax with ordinary web requests, asks its questions, reads the W-2 and 1099-INT the customer shares, and hands over the filing link; on the filing page the customer confirms their email with a one-time code, reviews the return, adds a card and signs. Transcript: demo/terminal-tax-demo-1.2.0.md.

The earlier recording, demo/terminal-tax-demo.mp4, shows the assistant's tool calls in a terminal.

工具

create_filing_session

Start filing session

Starts a filing session for a US federal individual income tax return when the taxpayer asks to file. Input: none. Output: a continuationHandle that identifies this filing session in later calls, and packetRules, the packet rules as text. This call receives no tax facts and creates no return and no link; the filing link comes with an accepted packet. A new filing session is also how a fresh link replaces one that expired or was left unfinished, through which nothing was filed or charged: the same packet sent on the new handle returns the new link. Covered returns: one original tax year 2025 US federal individual income tax return (Form 1040 or 1040-SR, and some Form 1040-SS and Form 1040-NR situations), with no state or local return. The packet rules this call returns list each covered and refused situation.

无需输入参数。

get_packet_schema

Get packet schema

Takes the filing session's continuationHandle. Returns the packet schema a completed return packet is checked against (the packet holds no Social Security number, ITIN or PIN: the taxpayer types those on the filing page): requestPacketSchema=true returns the schema digest (packetSchemaSha256, sent with the completed packet), an outline whose larger parts are named sections, the section list and the packetStarterTemplates list; packetSchemaSection=<name> returns one section and packetStarterTemplate=<id> one complete starter packet, in which each taxpayer-specific value is the placeholder REPLACE_WITH_TAXPAYER_VALUE, refused by path until replaced, with its askTheTaxpayer messages (the questions for the taxpayer) and each preset answer listed in presets with how it is settled. Read-only: no tax facts are sent here and no return is written. The tax year is return.taxYear=2025 inside the packet, not a tool argument; any other argument is refused by name.

输入参数continuationHandlepacketSchemaSectionrequestPacketSchemapacketStarterTemplate

continue_filing_session

Continue filing session

Checks the taxpayer's completed draft packet for a federal return and, when it passes, holds it as an unsigned draft and returns the link to the filing page; otherwise returns a list of problems to correct. This call files nothing and sends nothing to the IRS: the taxpayer reviews, signs and files on the filing page. Inputs: the filing session's continuationHandle, completedReturnPacketJson (the whole packet as one JSON string, in this server's packet schema) and packetSchemaSha256 (that schema's digest); other arguments are refused by name. The tax year is return.taxYear=2025 inside the packet. The packet carries the facts the taxpayer stated in this chat and the figures printed on documents the taxpayer gave in it; a fact the taxpayer has not stated is left out rather than written as no, none or 0, and a required fact that is left out comes back as a blocker asking for the taxpayer's answer. Output: status filing_session_ready with a filingSessionUrl when the packet is accepted; the taxpayer opens that link to give permission, review the return and sign it. Otherwise, blockers (each with a path, a rule and a plain detail) and no link; that packet is not kept, and the same handle accepts a corrected packet. Nothing is filed or charged through a link that expires or is left unfinished, and the same packet sent again with a new filing session's handle returns a fresh link. An accepted packet is held until the taxpayer gives permission on the filing page; declining there, or expiry, erases it. Federal returns: no state, territory or local return is filed. The return has no taxpayer identity fields: the taxpayer's own details go in the packet's separate, required agentIdentity section, which the filing page shows for the taxpayer to confirm. Business identifiers printed on each source form, such as an employer's or payer's name and EIN, are packet fields.
