Základné finančné koncepty a praktické výhľady pre moderné účtovníctvo
NEC is for services, MISC is for rent and royalties — both to recipients by Jan 31, but NEC also files to IRS by Jan 31. Miss it and the $60–$310 per-form ladder starts.
The March 2025 interim final rule exempted domestic reporting companies — foreign-registered entities must still report within 30 days, update within 30 of any change, at $591 per day for willful failure.
Staking, airdrops, and hard forks are ordinary income at fair value when you gain dominion and control — and every crypto-to-crypto swap is a sale with proceeds, basis, and gain.
280A(g) excludes 14 or fewer rental days — but the business deduction still needs business purpose and fair venue comps. Keep the agenda, sign-in, photos, and rate memo or the rent is recharacterized.
Restaurant meals are back to 50% after the 2022 100% boost expired — the real test is whether each meal has amount, time, place, purpose, and business relationship plus your presence.
Mileage bundles costs at 70 cents per mile but year-one actual unlocks Section 179 for heavy SUVs — pick the method before you place the vehicle in service and keep the daily log that makes either deduction survive.
Exclusive and regular use decides eligibility before math — then pick $5 per square foot up to $1,500 or actual allocations. Keep the dated floor plan that proves the room and the method that fits your sale timeline.
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The $100K-or-200 shorthand is wrong in most states in 2026 — many repealed the transaction test and three big states use $500K.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.
