Essential accounting and finance guidance for startup founders
Reg CF lets non-reporting U.S. companies sell securities to the public up to $5 million per rolling 12 months through an SEC-registered funding portal. This guide walks through the $124,000 investor limits, Form C disclosure, bad-actor checks, tombstone advertising, ongoing C-U and C-AR filings, and the bookkeeping for SAFEs, offering costs, and escrow that founders most often get wrong.
A 2026 reference for SaaS founders on calculating MRR and ARR, decomposing the five-bucket recurring-revenue waterfall, interpreting NRR/GRR, and reconciling subscription metrics to GAAP revenue under ASC 606.
The OBBBA raised the Section 1202 QSBS cap to $15 million, lifted the gross-asset ceiling to $75 million, and replaced the five-year cliff with a tiered 50/75/100 percent exclusion at three, four, and five years — but only for stock issued after July 4, 2025.
The Rule of 40 says a healthy SaaS company's revenue growth rate plus profit margin should clear 40%. This guide covers how to calculate it, which margin metric to use, 2026 benchmarks (median score around 12%), the Rule of X variant, and when the rule does not apply.
OBBBA's new Section 174A restores immediate expensing for domestic R&D in tax years after December 31, 2024, and qualifying small businesses can amend 2022–2024 returns by July 6, 2026 to recover overpaid tax. A guide to the three coexisting Section 174 regimes, the Section 41 credit add-back, foreign 15-year amortization, and the statement in lieu of Form 3115.
Section 195 and Section 248 let founders deduct the first $5,000 of startup costs and the first $5,000 of organizational costs in year one, with the remainder amortized over 180 months. A guide to the $50,000 phase-out, the deemed election, and the mistakes that forfeit the deduction for LLCs, partnerships, and corporations.
Section 409A taxes noncompliant deferred compensation in the year of vesting and adds a flat 20% federal penalty plus interest. This guide explains the short-term deferral and separation pay exceptions, the six recognized payout triggers, the six-month delay for specified employees, and how to structure bonuses, severance, RSUs, phantom stock, and discounted stock options so founders avoid the penalty.
A Section 83(b) election lets founders and early employees pay ordinary income tax today on the full value of restricted stock instead of at each vest. Filed within 30 days on IRS Form 15620, it can convert millions of phantom ordinary income into long-term capital gain and start the QSBS holding clock on day one.
Section 382 caps how fast an acquirer can use a target's net operating losses after an ownership change — annual limit equals the loss corporation's equity value times the long-term tax-exempt rate (about 3.58% in early 2026). Here is what triggers it and the legitimate workarounds.
Rule 506(b) and Rule 506(c) of Regulation D both allow uncapped private placements but differ sharply on marketing and verification. 506(b) bans general solicitation and permits up to 35 sophisticated non-accredited investors on a reasonable-belief standard; 506(c) permits public solicitation but requires reasonable steps to verify every purchaser is accredited. A March 2025 SEC no-action letter lets issuers rely on $200,000+ individual or $1 million+ entity minimum checks as the primary verification step.
Section 382 caps a startup's pre-ownership-change net operating loss deductions at the pre-change fair market value multiplied by the long-term tax-exempt rate (about 3.56 percent in February 2026), triggered when 5 percent shareholders collectively gain more than 50 percentage points over a rolling three-year testing period.
Section 83(i) lets qualified employees of qualified private companies defer federal income tax on RSU settlements and NSO exercises for up to five years. The 80 percent grant rule, mandatory escrow, and 30-day election deadline explain why adoption stays in the single digits — and when the election still pays off.
