Business finance strategies and accounting best practices for success
Average shrink is 1.4–1.6% of sales — booked as extra COGS only after a count. Stratify cycle counts by ABC, reconcile 3PL before booking, and show the reserve honestly every month.
Underpayment interest is daily and quarterly — hit the 100%/110% or 90% harbor and pay the right amount by April 15, June 15, September 15, and January 15, or use Schedule AI for seasonal income before Form 2210 bills you.
An unpaid invoice isn't automatically a deduction for cash-basis businesses and worthlessness must be proven in the year claimed — document business character, collection efforts, and the specific charge-off before December 31.
Deduct premiums on Schedule 1, get reimbursed via ICHRA/QSEHRA, or take the premium tax credit — never two for the same dollar. Master the month-by-month coordination and circular math that prevents double benefits.
The $100K-or-200 shorthand is wrong in most states in 2026 — many repealed the transaction test and three big states use $500K.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.
La décision fiscale 10050 du Trésor, en vigueur depuis le 10 juillet 2026, apporte la première mise à jour substantielle des réglementations sur la fiducie nationale qualifiée (QDOT) en trois décennies. Voici pourquoi la déduction maritale illimitée exclut les conjoints non citoyens, ce qu'exige une QDOT — un fiduciaire américain, une élection formelle sur le formulaire 706, et une garantie pour les fiducies de plus de 2 millions de dollars — et quelles sont les quatre corrections procédurales que les nouvelles règles apportent pour les successions des chefs d'entreprise.
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.
La définition actualisée de « healthy » par la FDA devient obligatoire le 25 février 2028 : les produits doivent apporter une quantité significative d'un groupe alimentaire et rester sous 10 % de la VQ en graisses saturées, 15 % de la VQ en sodium et 10 % de la VQ en sucres ajoutés par portion. Voici qui gagne l'éligibilité, qui la perd, ce que coûte la conformité (~$20 par UPC pour la mise à jour des étiquettes, ~$1M par formule reformulée), et un calendrier pratique pour les petites entreprises alimentaires.
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.
