Informational onlyInformational only. These twenty items stay refuse. They are product law, not a backlog and not a later-wave schedule.
Completeness includes what we will not ship. The twenty items in this library are informational: each names a hard no and a named instead-path. They are not tickets and they are not a later-wave schedule.
The tax engine stays Creytix Tax. Eligibility and rates live only in @creytix/tax-rules. Personalized write-off pitches, a Secretary of State e-file bureau, a second e-sign product, and a live IRS.gov scrape are out.
Public-record privacy is not concealment. FinCEN ended beneficial-ownership reports for U.S. companies and U.S. persons in August 2026. Do not treat a domestic BOI filing as required.
The full write-ups live on /tax/wont-build. This article exists so the Research library carries the same law as the refuse page.
Informational · 1 / 20
A product named Ledger
The tax engine is creytix-tax-engine. Ledger already means Cost Ledger and the chat harvest ledger.
Informational · 2 / 20
LLM-calculated tax, eligibility, or statutes
Models invent wage bases and elections. Math lives only in @creytix/tax-rules.
Informational · 3 / 20
Federal-bracket “total tax” calculator
Without filing status, QBI, NIIT, additional Medicare, and state rules, a “total tax” number is a lie.
Informational · 4 / 20
FlyFin / Keeper-style AI write-off finder
Personalized “write this off $X” is advice we are not licensed to give.
Informational · 5 / 20
Vehicle / Tesla / boat / aircraft write-off pitches
Listed-property rules are facts plus a CPA. A shopping list is marketing.
Informational · 6 / 20
Hire-your-kids-to-zero-the-tax schemes
Child-labor, reasonable-wage, and kiddie-tax facts are not a productized loophole.
Informational · 7 / 20
$80k–$100k S-corp salary heuristic
Reasonable compensation is professional judgment, not a blog percentage of profit.
Informational · 8 / 20
First-party Secretary of State e-file bureau
We are not CorpNet, Harbor, or LegalZoom. State portals and authorized transmitters exist.
Informational · 9 / 20
A second e-sign product
Creytix Sign is the envelope. Forking e-sign per tenant is the defect.
Informational · 10 / 20
Nominee kits, straw owners, or “hide from IRS/creditors”
Privacy is a public-record tradeoff. Concealment is out of product.
Informational · 11 / 20
FinCEN BOI as a current U.S. company duty
The August 14, 2026 final rule ended BOI for U.S. companies and U.S. persons.
Informational · 12 / 20
Alter-ego / piercing / charging-order guarantees
Courts look at capitalization, commingling, and formalities. Software cannot insure the veil.
Informational · 13 / 20
QBI, NIIT, PTET-savings, or QSBS exclusion engines
Those need return-level facts we will not invent. PTET is a state election, not a federal hack.
Informational · 14 / 20
Wayfair sales-tax rate calculator
Nexus and rates are a specialist engine. Guessing a rate is worse than a calendar.
Informational · 15 / 20
Fundraising cap-table product (Carta/Pulley clone)
A stock ledger for formalities is not priced rounds, SAFEs, and 409A.
Informational · 16 / 20
Gusto / ADP as the payroll home
Payroll is in-suite (creytix-payroll). Providers are import fallbacks, not the home.
Informational · 17 / 20
IRS Direct File clone
Direct File is not a Filing Season 2026 path. Free File remains the IRS free option when you qualify.
Informational · 18 / 20
Practicing law or Circular 230 return preparation in Wave 0–4
Unauthorized practice and E&O. Template-population is not counsel.
Informational · 19 / 20
Fake live IRS.gov ticker
Unreviewed HTML scrape is how stale BOI and wrong wage bases ship.
Informational · 20 / 20
Trust mill / asset-protection kit as a productized dodge
Grantor vs non-grantor tax and charging-order outcomes are attorney work.
