Nothing to run from here
Arc & Ledger Tax Reference is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http arc-ledger-tax-reference-mcp https://mcp.arcandledger.com/directory/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.

Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Use when a user provides the code from an IRS notice or letter and wants a general explanation, the usual response window, or the next procedural step. Do not request the notice itself or any taxpayer identifier.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| notice_code | string | yes | The notice or letter code printed on the IRS mail, e.g. "CP2000", "CP 14", "LT11", "Letter 1058". |
| received_date | string | no | Date on the notice (YYYY-MM-DD). Used to compute the response deadline. The IRS clock runs from the notice date printed on the letter. |
| amount_shown | number | no | The dollar amount the notice proposes or bills, if any. Optional; used only for context, never stored. |
| brief | boolean | no | Set true for a shorter answer: skips the generic how-to-read guidance and common-error list. |
Use to screen general IRS payment and collection alternatives from a rough balance, filing-compliance status, ability-to-pay category, and coarse tax-account type when known. This is an educational fit screen, not a promise that the IRS will approve an option.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| balance_owed_usd | number | yes | Total amount owed to the IRS including tax, penalties, and interest (a rough figure is fine). |
| all_required_returns_filed | boolean | no | Whether every required tax return has actually been FILED (even if the tax was not paid). Filing compliance is generally required before the IRS formalizes a collection alternative, but the exact acco |
| tax_account_type | string | no | Coarse, nonidentifying IRS account type. individual_income_tax includes Form 1040 income-tax balances, including a sole proprietor whose balance is on Form 1040. business_non_trust_fund_or_out_of_busi |

| balance_includes_penalties | boolean | no | Whether the balance includes failure-to-file or failure-to-pay penalties, so penalty abatement may reduce it. Defaults to true. |
| brief | boolean | no | Set true for a shorter answer: options come back as path + fit only, without the descriptions. |
Use to estimate selected federal failure-to-file, failure-to-pay, and underpayment amounts from nonidentifying figures. The result is an estimate and does not replace an IRS account transcript.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| balance_owed_usd | number | yes | The unpaid tax balance (the tax itself, before penalties and interest). |
| months_late | number | yes | Whole months past the deadline. The failure-to-file penalty counts any part of a month as a full month. |
| return_filed | boolean | no | Whether you actually FILED the return (even if you did not pay). If false, the larger 5%/month failure-to-file penalty applies. Defaults to false (not filed). |
Use when a user names a US tax form or information document and wants to understand its purpose, common fields, or usual return treatment. Do not request or accept the document itself.
| Parameter | Type | Required | Notes |

| brief | boolean | no | Set true for a shorter answer: skips the box-by-box guide and the pre-filing checklist. |

| Parameter | Type | Required | Notes |

| filing_year | integer | no | The tax year whose deadlines you want (the year being reported). Defaults to the prior calendar year. |
| has_us_source_wages | boolean | no | Nonresident individuals only: whether you had US wages subject to withholding. Determines the 1040-NR due date (April 15 if yes, June 15 if no). |
| has_foreign_bank_over_10k | boolean | no | Whether the aggregate of your foreign financial accounts exceeded $10,000 at any point (triggers FBAR). |
| formed_in_us | boolean | no | Whether the entity was formed in the US (relevant to the BOI report, from which most US-formed companies are now exempt). |
Use to screen general FBAR and Form 8938 thresholds from aggregate balance, filing status, residence, and account-count facts. Do not request account numbers, institution names, or statements.

| payee_type | string | no | Whether the payee is an individual or a company/entity. Defaults to individual. Determines the form (W-8BEN vs W-8BEN-E) and the treaty dividend rate. |
Use to screen general ITIN reason categories, whether a return is commonly attached, and supporting-document requirements. Never request or process an actual ITIN, passport, or identity document.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| has_ssn | boolean | yes | Whether you already have, or are eligible for, a US Social Security Number. If yes, you cannot get an ITIN. |

| is_foreign_national | boolean | no | Whether you are a non-US citizen without US immigration status that grants an SSN. Defaults to true. |
Use to screen common Form 5472 triggers for a foreign-owned US disregarded entity or corporation. The result is a general filing screen and does not prepare or file the form.

| formed_in_us | boolean | no | Whether the entity was formed in the US (a Wyoming or Delaware LLC is US-formed). Relevant only to the separate BOI report, from which US-formed companies are now exempt. |
Use to estimate federal quarterly tax payments from nonidentifying income, entity, withholding, and prior-year tax figures. Return the assumptions, safe-harbor context, and due dates.

| entity | string | yes | How the income is taxed. Sole proprietor / SMLLC / partnership pay self-employment tax; S-corp shareholders take wages (withheld) plus distributions. |

| prior_year_total_tax_usd | number | no | Total federal tax on last year's return. Enables the prior-year safe harbor (often the easiest to hit). |
| prior_year_agi_usd | number | no | Last year's adjusted gross income (AGI). If over $150,000 ($75,000 MFS), the prior-year safe harbor rises from 100% to 110%. |

Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.
