ledger-config: parse gets a sourced spec. A fiscal year starts on the first of a month (IRS Pub. 538); tax_classification is read by whole words (Treas. Reg. 301.7701-3, Schedule C instructions; "business corp" no longer reads as an S corp, "corporation or S corporation" is refused); duplicate or blank members and shared capital accounts are refused; a negative or non-grammatical receipt threshold is refused; codes trimmed. tests/spec_config.rs (65 spec-blind tests, 14 properties), fuzz target fuzz_config_parse (weekly). Mutation: 55 of 55 viable caught (from 25/38). The receipt policy moves to ledger-config, with one loader (effective_receipt_policy) and one decimal grammar, so the server and the viewer enforce and show the same rule (the viewer had its own: only expense-like debits, a silent $25 default, and no config.json). ledger-mcp: a module spec (MCP 2025-06-18 tools, JSON-RPC 2.0, the operating contract). Amounts in are exactly -?digits[.digits]; a number that is one account's code and another's id (vendors, classes alike) is refused, not guessed; the threshold is validated at startup. Fixed: add_line with a bad class journaled the line before refusing; profit_and_loss_by_class ignored `class`; aging buckets said "0". A wire in front of rmcp answers malformed JSON with -32700 and invalid requests with -32600 and their id (rmcp dropped the first, omitted the id). tests/spec_mcp.rs (26 spec-blind tests: every tool's result against its own outputSchema, a random-call state machine checking the journal is untouched by every refusal, amount grammar, previews, the receipt policy). ledger-gui: money, accounting, and dollars never round (they rounded to cents, banker's style); export file names avoid Windows device names, trailing dots and spaces, empty names, and 255-byte overflow; specs on attention, history, fuzzy search, and axis ticks. ledger-core: the lifetime profit_and_loss is renamed unclosed_earnings (docs/testing.md #3).

# Entity classification: which return a business files
|
|
|
|
Governs `ledger_config`'s reading of `[company] tax_classification`.
|
|
Fetched 2026-10-14.
|
|
|
|
## Treas. Reg. §301.7701-3 (eCFR, via law.cornell.edu/cfr/text/26/301.7701-3)
|
|
|
|
**(a) In general**
|
|
|
|
> A business entity that is not classified as a corporation under
|
|
> § 301.7701-2(b) (1), (3), (4), (5), (6), (7), or (8) (an eligible
|
|
> entity) can elect its classification for federal tax purposes as
|
|
> provided in this section. An eligible entity with at least two members
|
|
> can elect to be classified as either an association (and thus a
|
|
> corporation under § 301.7701-2(b)(2)) or a partnership, and an eligible
|
|
> entity with a single owner can elect to be classified as an association
|
|
> or to be disregarded as an entity separate from its owner.
|
|
|
|
**(b)(1) Domestic eligible entities**
|
|
|
|
> Except as provided in paragraph (b)(3) of this section, unless the
|
|
> entity elects otherwise, a domestic eligible entity is— (i) A
|
|
> partnership if it has two or more members; or (ii) Disregarded as an
|
|
> entity separate from its owner if it has a single owner.
|
|
|
|
## Instructions for Schedule C (Form 1040) (2025), "Single-member limited liability company (LLC)"
|
|
|
|
> Generally, a single-member domestic LLC is not treated as a separate
|
|
> entity for federal income tax purposes. If you are the sole member of a
|
|
> domestic LLC, file Schedule C (or Schedule E or F, if applicable) unless
|
|
> you have elected to treat the domestic LLC as a corporation.
|
|
|
|
## The returns (titles, from irs-tax-lines.md)
|
|
|
|
- Form 1065, U.S. Return of Partnership Income: a partnership.
|
|
- Form 1120-S, U.S. Income Tax Return for an S Corporation: an S
|
|
corporation.
|
|
- Form 1120, U.S. Corporation Income Tax Return: a corporation (an
|
|
association included) that is not an S corporation.
|
|
|
|
## Derived (wanderbooks)
|
|
|
|
| classification says | return |
|
|
|---|---|
|
|
| partnership | Form 1065 |
|
|
| S corporation (S corp, S-corp) | Form 1120-S |
|
|
| C corporation; corporation, corp, or association alone | Form 1120 |
|
|
| disregarded entity, sole proprietor(ship), single-member | Schedule C |
|
|
|
|
A phrase naming two returns ("corporation or S corporation") and anything
|
|
else names no return wanderbooks can be sure of, so it is
|
|
refused rather than guessed.
