Every article and calculator published on East Corp Capital undergoes statutory verification to ensure that primary US federal, state, and municipal code citations are accurately represented and clearly distinguished from personalized legal or CPA representation:
- Primary Statutory Citation Audit: Verifying exact code sections across the Internal Revenue Code (IRC §§ 121, 408(d)(2), 1031, 1250, 1411, 5891; Treas. Reg. § 31.3402(g)-1), New York Tax Law (§ 255 CEMA mortgage assignments, § 601 personal income tax, § 1402-a Mansion Tax), New York Limited Liability Company Law (§ 206 62-county newspaper publication mandate), New Jersey Gross Income Tax Act (N.J.S.A. 54A:8-9 Form GIT/REP-1 non-resident seller withholding), and Florida Statutes (F.S. §§ 199.133 & 201.02).

- Strict YMYL & Non-Bank Disclosure Enforcement: Ensuring every study and simulator explicitly informs readers that models are educational and informational, that East Corp Capital is an independent broadsheet (not a bank, lender, or law/CPA firm), and that complex multi-state transactions require individualized counsel.
