A 25,000 dollar invoice on net 60 terms and payroll on Friday. This guide prices the three instruments that buy the time between the invoice and the money: a revolving line, a term loan, and factoring, with the SBA 7(a) backstop and the UCC lien behind them.
A $120,000 annual contract paid on January 1 is $10,000 of monthly revenue, not $120,000 of January revenue. This guide runs the waterfall, the tax election, and the churn math.
Two forms split every payee on earth into two populations, and the wrong form applies the wrong withholding rate. This guide works Form W-9 against Form W-8BEN on the same 60,000 dollar payment — 24 percent backup withholding against 30 percent chapter 3 withholding — with the statute text behind every rate.
Line 31 decides everything downstream: income tax, the 15.3 percent self-employment tax, and estimated-tax safe harbors. This guide runs one freelancer from $96,000 of gross receipts to a $56,660 net profit, line by line.
The partnership pays no federal income tax — and that is the trap. Form 1065 is an information return with a March 16, 2026 deadline, a $255-per-partner-per-month penalty, and a K-1 delivery rule that runs on the same clock as the return.
The $600 threshold is gone. A payment platform reports only above $20,000 and 200 transactions — and the number on the form is gross, never profit. This guide reconciles box 1a to Schedule C line 1, dollar by dollar.
The 1099-NEC threshold for 2026 payments is $2,000, not $600, and the form is due January 31 to both the IRS and the contractor. This playbook runs the per-payee aggregate test, the backup withholding math, and the $60 to $680 penalty ladder on one payer.
One return passes income to shareholders; the other taxes the corporation itself. The same $160,000 profit costs $28,380 as an S corporation and $52,560 as a C corporation — this guide prices both from the statute.
The S corporation election is a deadline, not a decision: miss the 2-month-15-day window and the corporation pays tax as a C corporation for the whole year. This guide works the deadline from the statute, the late-relief procedure, and the revocation rules.
Owning a foreign corporation creates a U.S. filing duty the day the shares are issued. This guide maps the five filer categories, prices the $10,000-per-year penalty ladder, and runs the GILTI math at the current 12.6 percent effective rate.
Form 941 is a quarterly return, not a payment, and most penalties come from the deposit schedule, not the form. This playbook runs the 2026 rates, the monthly and semiweekly deposit rules, the $100,000 next-day rule, and the 2 to 15 percent penalty ladder against one worked payroll, so the return and the money arrive on the right rails.
Every employee you paid in 2026 gets one document that settles the year. This playbook works the February 1, 2027 filing and furnishing deadlines, the box-by-box reconciliation, the 184,500 dollar wage base, and the 60 to 690 dollar penalty ladder — with the March 3 check that keeps a 60 dollar error from becoming a 340 dollar one.
A ten-day close is a business learning about itself ten days late. This guide sequences the month-end close into five business days: cutoff, accruals, reconciliations, flux review, and sign-off, with the SEC deadlines and SOX 302 certification that bound the calendar.
PCI DSS follows card data, not your org chart. This playbook maps the twelve requirements, the Level 1 to Level 4 volume table, the SAQ A to SAQ D ladder, and the scope math that moves a SaaS from 300-plus controls to the shortest questionnaire it honestly earns.
None of the three publishes a rate card. Plaid sells five billing shapes with no numbers, Yodlee sells an enterprise subscription, Finicity sells through Mastercard — and the only published price list belongs to a fourth vendor.
A New Jersey couple pays $52,000 of state and local tax and deducts $40,000 of it for 2025. This guide runs the statute, the phase-down, and the pass-through workaround.
A $900,000 interest bill meets a $870,000 cap under the old EBIT rule and a $1,230,000 cap under the restored EBITDA rule. This guide runs the formula, the carryforward, and the 2026 changes.
Section 199A gives pass-through owners up to 20 percent of qualified business income, but three limits decide the real number: the taxable-income cap, the wage-and-capital limit, and the specified service phaseout. This playbook runs the statute, the 2025 and 2026 threshold tables, and three worked scenarios so the deduction on the return matches the deduction in the law.
A Solo 401(k) adds a $23,500 elective deferral on top of the employer contribution; a SEP IRA has no deferral bucket at all. Worked 2025 and 2026 math at $120,000 and $300,000 of net earnings, plus the hire that breaks each plan, decides which one your income actually supports.
Three processors, three meters: Stripe charges per transaction, Square charges per plan and per channel, and PayPal charges per payment type. This guide prices all three at 10,000, 50,000, and 200,000 dollars a month, at a 50 dollar average order — with the break-even volumes and the dispute math.
An intercompany service charge is a price, and the IRS tests it like one. This playbook works the arms-length standard, the five specified methods plus the services cost method, the 7 percent low-margin test, and the 20 and 40 percent penalty math — with the documentation that defends it.
A SaaS contract is not revenue when the invoice goes out. Under FASB ASC 606, revenue follows the promises in the contract, priced at standalone selling price, and recognized as each promise is satisfied. This guide works the five steps, the allocation math, and the deferred-revenue schedule on a real contract.
Manual reconciliation fails at volume, not at accuracy — the math of exception queues proves it. This playbook sets the match-rate targets, the exception aging rules, and the ASC 830 remeasurement sequence that keep a multi-currency ledger reconcilable at close.
Revenue is a promise with a date on it; cash is the promise kept. The cash conversion cycle measures the gap in days, and three levers — inventory, receivables, and payables — decide how wide it runs.
Dissolution starts the end, winding up settles it, and cancellation files it. Delaware §§ 18-801 to 18-804 and Wyoming §§ 17-29-701 and 17-29-702 set the order, the $220 and $60 state fees, and the December 31 tax trap that punishes a slow exit.
Delaware lets every stock corporation pay the lesser of two franchise tax methods, and the gap between them can exceed $80,000 on the same capital structure. This guide runs both methods with the Division of Corporations figures, so you file the smaller number on purpose instead of by default.
Gusto, QuickBooks Payroll, and Rippling all run payroll, but their bills diverge on base fees, tier steps, and quotes. This playbook prices all three per employee at 10 and 25 headcount and sets the software bill against the employer tax bill it exists to get right.
Two methods compute the same credit and routinely produce different answers. The regular method rewards a high fixed-base percentage history; the ASC rewards recent growth. Run both before electing, because the ASC election sticks.
For tax years beginning after December 31, 2024, domestic software development costs are deductible again under new IRC § 174A, while foreign research stays capitalized over 15 years under § 174. This guide covers the statute, the Rev. Proc. 2025-28 elections, the stranded 2022–2024 balances, and the math that decides which path to take.
Early exercise only pays off if the 83(b) election is filed within 30 days of transfer, not vesting. This playbook covers the regulation line by line, the ISO and NSO math, the AMT surprise, and the forfeiture cost of getting it wrong.
Northwest charges $39 plus state fees, Atlas charges $500 all-in, and Clerky charges $819 bundled for the same Delaware C corporation. The cheapest route depends on Delaware state fees, the second-year agent renewal, and the add-ons each package excludes, so this guide prices all three to year two.
Visa folded fraud reports and disputes into one ratio, then revised the thresholds twice in eighteen months. Most published guides still print the superseded numbers. Here are the current lines, the math that decides enrollment, and the defenses that actually move the numerator.
South Dakota v. Wayfair ended the physical-presence shield in 2018, and the audit wave it created is still arriving. This playbook prices historical exposure state by state, sequences voluntary disclosure against registration-first filing, and sets the record protocol auditors actually test.
Three vendors, three pricing philosophies: Wise prices the conversion, Airwallex prices the rail, Payoneer prices the corridor. On a $5,000 contractor payout the spread runs from about $12 to over $50 — and the cheapest rail on one corridor is the most expensive on the next.
