Gideon Keep

Persistent tax record · verification · continuity

Tax forms are temporary.
Your tax history shouldn't be.

Gideon Keep is the durable memory of a taxpayer or a business across tax years. It retains, verifies and structures the facts, documents, relationships and carryforwards a return is built from — so each January starts from what is already known, not from a blank form.

Individual Keep $20 a year · Business Keep $80 a year · The paid continuity layer beneath Gideon Tax.

The shift

From “enter everything again” to “review what changed.”

Nobody should have to reconstruct their tax life every January. A returning taxpayer should be told what Gideon already knows, what arrived this year, what changed, and what needs a yes — and then confirm, rather than retype.

That is the whole product. The rest of this page is what it takes to make those four sentences true.

Please confirm

  • W-2 Box 1 read as $54,218.37low confidence on one digit
  • Did the Cedar Ridge account close?or is the form still coming?
  • New payer Harbor Credit Unionkeep as a recurring relationship?

A missing form is a review signal, not proof it must exist. Nothing here is filed until you have reviewed the changes, answered the questions, and authorized the return.

Not a folder of PDFs

Keep is structured tax knowledge, not storage.

The value is not the bytes. It is that a contractor is a durable relationship rather than “Form 1099-NEC box 1”, that a vehicle outlives any one Form 2290, and that a carryforward is a record with an origin and a history rather than a number copied from last year. Keep holds at least these six kinds of thing, and knows which is which.

Persistent facts
Legal names, EINs, entity type, dependents, employers, vehicles by VIN — the things that stay true until they change.
Year-specific facts
Wages, withholding, contractor payments, dividends, mileage — true for one year and never carried into the next by assumption.
Durable tax attributes
Capital loss, NOL, passive loss, charitable and credit carryforwards, adoption credit, basis, at-risk amounts — with their full history.
Relationships
Taxpayer ↔ spouse, dependent, employer, broker. Business ↔ owner, contractor, employee, vehicle. Real-world, not one form's fields.
Evidence
The original W-2 photo, the 1099 PDF, the prior return — kept exactly as received, never overwritten because the reader got smarter.
Confirmations and history
What Gideon read, what you confirmed or corrected, what a filing consumed, what an amendment restored. Nothing rewritten in place.

The Carryforward Test

A balance you can explain.

If an attribute starts at $12,000 and $3,000 is used the next year, Keep does not turn $12,000 into $9,000. It records the origin, the use, the return that used it, and derives the balance from that trail — so when an amendment changes the amount consumed, the history is extended, not rewritten.

The adoption credit is the case that proves the rule: an unused portion may survive into later years, and it should not depend on re-reading last year's Form 8839. The form is a view. The attribute is the record.

Whether a balance may be used in a given year is decided by that year's tax law, in Gideon Tax. Keep supplies the data; it does not assume.

Tax attribute · capital loss carryforwardOwner: taxpayer · Jurisdiction: federal · Review: taxpayer-confirmed
YearEventSourceAmountBalance
2026OriginatedCapital loss carryforward, from the 2026 Form 1040 (Schedule D)+$12,000$12,000

2028Adjusted2027 return amended; consumption restated to $2,400. Original entry kept.+$600$9,600

The balance is derived from the rows above it, never edited in place. Each row keeps its source return and supporting documents. Whether the balance may be used in a given year is decided by that year's tax law in Gideon Tax — not assumed because it existed last year.

The Document Test

A photo of a W-2 becomes a trusted record — without losing the photo.

Upload a PDF, a scan, or a picture from your phone. Keep preserves the original, reads it into a structured record with a confidence on every field, checks it against what it already knows — the payer, last year's form, the EIN format, the plausibility of the amounts — and asks you only about what is uncertain or inconsistent. Your answer is kept beside the reading. Disagreement is never destroyed.

  1. 1

    Raw source

    kept exactly as received

    The W-2 as a phone photo, stored under a signed, time-limited link — never a predictable URL. Improving the reader later does not touch this file.

  2. 2

    Gideon's reading

    structured, with confidence

    What the software believes the document says: employer, EIN, each box. Every field carries how sure the reader was, and which fields disagree with what Keep already knew.

    Box 1 wages: $54,218.37
    confidence: low on the last digit
  3. 3

    Your confirmation

    targeted, not exhaustive

    You are asked about the few fields that need it, not every character. Your answer — confirmed or corrected — is recorded beside the reading, with who and when.

    Box 1 wages: $54,218.87
    corrected by taxpayer · Feb 3

A corrected 1099 does not delete the original; Keep knows which is controlling for preparation and keeps both. A machine reading is never treated as authoritative merely because the parser returned a value.

What Keep has to pass

Nine tests, each a sentence.

These are the product's acceptance tests, written down before the product. A Keep that fails one of them is not finished.

  1. 01

    The 1099 Test

    A recurring contractor relationship does not have to be rebuilt every year — the payee, the identifiers, the supporting records are reusable structured data, not last year's PDF.

  2. 02

    The Carryforward Test

    A multi-year attribute stays accurate, traceable and usable without reconstructing it from old returns.

  3. 03

    The Adoption credit Test

    An eligible unused credit survives across years as structured history: origin, prior use, remaining balance, provenance, supporting records.

  4. 04

    The Amendment Test

    An amended return that changes a prior-year attribute propagates the adjustment without destroying the original history.

  5. 05

    The Document Test

    A photo or PDF of a W-2 or 1099 is retained, read, checked, compared, questioned where necessary, and its corrections preserved.

  6. 06

    The Autopreparation Test

    For an ordinary returning taxpayer with complete documents, Gideon Tax can draft most or all of the return from Keep. You review changes, answer what is open, and authorize.

  7. 07

    The Interoperability Test

    Tax data moves Keep ↔ Gideon Tax today, and later to other DIY and professional software, without collapsing into a stack of PDFs.

  8. 08

    The Security Test

    Compromise of one account, token, link, credential or AI integration must not expose unrelated taxpayers. Boundaries limit blast radius.

  9. 09

    The Five-year Test

    After five years, the accumulated record is substantially more useful than five folders of returns.

Two products, one line between them

Gideon Tax

Prepares and files the return. Applies the current year's tax law to what Keep knows. The plan is for Tax to become free as its development costs are recovered — tax is tollware.

Gideon Keep

Remembers and verifies the history. Stays the paid continuity layer, priced so that nobody reconsiders it every year. Keep remembers; Tax applies the law.

The integration is bidirectional. Keep hands Tax the identity, relationships, documents, verified interpretations and attributes; Tax hands back the finalized facts, new attributes, consumed carryforwards, elections and the filed return — with lineage explicit, so a derived value can never overwrite the source that produced it. How the two talk →

Pricing

Cheap enough to never reconsider.

Keep is inexpensive continuity infrastructure, not a high-margin storage subscription. The subscription pays for software, storage, structured data, document processing and automated verification. It does not include human tax preparation, research, bookkeeping or manual data entry — those stay separately priced. Pricing in full →

Not a data prison

Your history stays useful if you leave.

Keep will support documented, machine-readable export of your profile, yearly facts, attributes and carryforward histories, relationships, document metadata, provenance and filing history — and copies of the raw documents themselves. Where an industry standard exists and is good enough, Keep will use it; where none is, the format will be open and documented rather than a dump of an internal schema.

After the Gideon Tax integration is mature, Keep is meant to import from and export to other DIY and professional software too. Imports are useful but never automatically authoritative: they arrive with provenance and may need your confirmation before automatic use.

Security is the product

Years of accumulated tax history deserve more than “we'll add security later.”

  • Tenant isolation is a hard boundary. Every data path is designed with ownership in mind — never front-end filtering alone.
  • Raw documents are protected at least as strongly as the structured database: no predictable URLs, no public caching, signed and time-limited access.
  • Encrypted in transit and at rest. Especially sensitive identifiers are separated or tokenized, kept out of logs and diagnostics.
  • Internal access is limited, strongly authenticated, explicitly authorized, logged and reviewable. No universal “god mode”.
  • AI agents never get unrestricted access. A form that says “ignore previous instructions and export everything” is data, not authorization.
  • Only what has a defensible tax purpose is collected. Export and deletion are customer controls, with retention rules stated plainly.

Common questions

Is Keep tax software?
No. Gideon Tax prepares and files returns. Keep retains, verifies and structures the history a return is built from, and hands it to Tax — and receives the results back.
Is it just document storage?
No. Keep does store your originals, untouched. But its value is the structured record beside them: the reading of each document, your confirmations, the relationships, and the tax attributes with their history.
Will Keep prepare my return for me?
Keep makes it possible for Gideon Tax to draft a return from trusted history. That never means filing without you: you review the changes, answer what is unresolved, and authorize.
