Essential accounting and finance guidance for startup founders
Form 15620 can now be submitted through an IRS Online Account, but the 83(b) election's 30-day deadline still has no routine extension. How the election works, when it pays, how to file online or by certified mail, and the six mistakes that sink it.
A five-factor framework — 36-month total cost of ownership, time to value, differentiation, integration, and compliance risk — for deciding which SaaS financial tooling to buy and which to build, with a worked example at $20,000 MRR where buying a billing engine costs roughly $25,000–$45,000 against $50,000–$100,000+ to build one.
RSUs are taxed as ordinary income on the vesting date, not at sale, and employers withhold a flat 22% on supplemental wages up to $1 million — leaving employees in the 32–37% brackets short by 10 to 15 percentage points each April. This guide covers double-trigger vesting at private startups, why no 83(b) election exists for RSUs, and the $0 cost-basis error on Form 1099-B that makes people pay tax twice on the same income.
AWS Activate credits are a discount, not income — record the gross cloud expense and net the credits against it in a contra-expense account, then forecast gross burn and the expiry date so your runway math survives the month the subsidy ends.
A provisional patent application costs $325, $130, or $65 depending on entity size, establishes a priority date, and lets you say "patent pending" — but it is never examined and goes abandoned exactly 12 months after filing, a statutory deadline that cannot be extended. Here is what to file, how to qualify for micro-entity status, and how to track the costs.
Paying a contractor does not transfer intellectual property. Under U.S. law the creator owns the copyright and the inventor owns the patent rights unless a signed writing says otherwise, and "work made for hire" language covers only nine narrow statutory categories that exclude custom software. This guide covers the seven clauses a contractor IP assignment needs, why "hereby assigns" beats "agrees to assign," and what investors check in diligence.
Illinois's Artificial Intelligence Safety Measures Act, signed July 6, 2026, requires frontier AI developers with over $500M revenue to publish catastrophic-risk frameworks, pass annual independent audits, and report safety incidents within 72 hours starting January 1, 2028. This guide breaks down the five obligations, audit costs of $25,000–$150,000+, and a 16-month preparation timeline for startups.
California does not conform to Section 1202, so a QSBS gain that is 100% excluded federally is taxed in full at state rates up to 13.3% — a $4 million exit can leave a founder owing roughly $350,000–$450,000 to Sacramento. This guide covers the 2025 QSBS expansion's new three- and four-year tiers, why California repealed its own exclusion, the real math on graduated brackets and the 1% surcharge, and what an FTB residency audit demands from founders who move before selling.
The SEC's May 2026 proposals would extend scaled disclosure to all non-accelerated filers — over 80% of public companies — shield new issuers from large-accelerated-filer status for 60 months, drop the SOX 404(b) auditor attestation, and allow semiannual reporting. Here is what the reforms could save a small company, and the IPO-readiness bookkeeping checklist to run now.
California's AI Transparency Act (SB 942) became operative on August 2, 2026 after AB 853 pushed back its January start. Generative AI providers with more than one million monthly California visitors or users must offer a free detection tool with upload, URL and API intake, an optional visible label, and a mandatory latent watermark, revoke licenses within 96 hours of discovering tampering, and face $5,000 per violation per day. This guide covers who is a covered provider, the 2027 platform and 2028 capture-device phase-ins, a compliance checklist, and how to budget and book the program.
Under ASC 718 as amended by ASU 2018-07, startup equity granted to consultants, advisors, and contractors is measured at grant-date fair value and expensed as services are received — not when cash moves. This guide covers scope decisions, option-pricing inputs and nonpublic-company practical expedients, service vs. performance vs. market vesting conditions, keeping book expense separate from tax reporting, a three-record monthly reconciliation, and the ASU 2025-04 change for customer awards effective after December 15, 2026.
A co-founder prenup records capital contributions, equity splits, vesting, spending authority, salary triggers, and exit terms before the first dollar moves — Carta data shows only 45.9% of two-founder startups incorporated in 2024 split equity equally — and maps each decision to ledger entries your accountant can verify.
