Concepts financiers essentiels et perspectives pratiques pour la comptabilité moderne
The $100K-or-200 shorthand is wrong in most states in 2026 — many repealed the transaction test and three big states use $500K. Track gross by state and channel before the notice does.
Federal relief says $5,000 but most states still require $600 — a form in the mailbox may be state-driven. Reconcile per-TPSO gross to taxable income and don't pay tax on mis-coded reimbursements.
Solo owner with $140K profit can do $28K SEP, $35K Solo 401(k), or $16K SIMPLE — same profit, different deductions. Match the plan to employees, profit, and whether you need the deduction by December 31 or April 15.
199A's 20% QBI deduction sunsets after 2025 as written — model the cliff by your actual capped deduction and marginal rate, revisit salary and retirement timing, and track W-2/UBIA for a retroactive extension.
A small building's first-year deduction can triple with cost segregation — reclassify 5-year, 7-year, and 15-year pieces, elect Section 179/bonus where it helps, and document the allocation the ATG expects.
Since 2022 research costs must be capitalized over 5 years — software included — midpoint in year one. Track domestic vs foreign, build the amortization schedule, and be ready for OBBBA's retroactive expensing.
Detailing margins live per job — price per ticket, cost chemicals per job, expense the van via Section 179/bonus, defer coating warranty revenue, and run on revenue per job and net margin after owner labor.
Valeur Économique Ajoutée (EVA) = NOPAT − (WACC × capital investi) — le profit restant après que chaque source de capital, dette et capitaux propres confondus, soit rémunérée à son taux courant. Un exemple pratique, comment estimer le NOPAT et le WACC, pourquoi l'EVA évite le biais du pourcentage du ROI, et comment les propriétaires de petites entreprises peuvent l'utiliser pour les décisions d'investissement.
Every state requires breach notice and size doesn't exempt you — map the 30/45/60-day clocks, California SB 446's 30-day and 15-day AG rule, 500/1000 thresholds, risk-of-harm, and run on the shortest deadline.
U-pick berries are farm income, admissions and donuts are not — split Schedule F and C, track per-enterprise contribution, tax admissions and prepared food, reconcile Square, and run on revenue per acre and per visitor.
Every audition is unpaid labor — track per-job gross vs commission, pass exclusive-use for the home booth, expense gear via Section 179/bonus, allocate buyouts over usage, and run on revenue per audition.
Retainers are deferred revenue or client trust — track per case, job-cost hours, mileage, advances and subcontractors, classify investigators on control, and run on realization and recovered-expense recovery.
