OBBBA Chapter 3 — Business & International Tax Changes (Sections 70301–70354)

Chapter 3 of One Big Beautiful Bill Act (OBBBA) (Sections 70301–70354) changes deductions, credits, interest limits, and international rules in ways that are easy to miss under deadline pressure. This page turns the law into timing checklists, election choices, and workpapers you can ship.

The pain you’re dealing with

• Timing pressure: Getting assets “placed in service” on the right side of Jan 19, 2025 for 100% bonus while clients keep moving install dates.
• Choice overload: Balancing §179 ($2.5M/$4M) vs bonus vs §168(n) without tripping basis reductions or state non-conformity.
• R&D whiplash: Re-wiring ledgers for §174A domestic expenses after 12/31/2025, coordinating with §41 so nothing double counts.
• Interest math drift: Rebuilding §163(j) with a permanent add-back and new “don’t capitalize disallowed” ordering.
• Documentation burden: Drafting clean election statements, policy addenda, and client memos that reviewers will actually sign off on.
• International remap: Collapsing FTC baskets, recalculating §250 (FDEI/NCTI) with QBAI = 5%, tracking day-count CFC inclusions, and explaining it all to finance.
• Client comms: Sending short, accurate emails that convert decisions into action—without a 20-page memo every time.
• Team ramp-up: Getting juniors productive on new rules before the next filing wave hits.

How can CPA Pilot help with this change?

• Generate election statements, client emails, and workpapers in minutes.
• Run bonus vs §179 vs §168(n) comparisons and §163(j) calculators with audit-friendly outputs.
• Build §250/FTC/CFC worksheets (including day-count) without reinventing the model each time.

Quick-Start Checklist

1. Time capex for 100% bonus: Assets “ready and available for use” after Jan 19, 2025. Consider the one-year 40%/60% election if smoothing income helps.
2. Update §179 policy: Use $2.5M / $4M and model state conformity.
3. Stack advanced manufacturing (§168(n) + §48D): Confirm construction windows, split qualifying vs non-qualifying areas, and model deduction-first vs credit-first.
4. Stand up domestic R&D expensing (§174A): Tag “domestic” costs; choose expense now vs amortize ≥60 months; coordinate with §41.
5. Rebuild §163(j): Permanent add-back to ATI, apply “capitalize allowed first; don’t capitalize disallowed.”
6. Meals exception (remote fishing): Add a separate GL if relevant; capture location evidence.
7. International reset: Two FTC baskets, §250 updates (FDEI/NCTI, QBAI 5%, direct-expense rule), CFC day-count tracking, §951B exposure.
8. One-month deferral repeal: Calendars aligned; first post-repeal year ends Nov 30, 2025.
9. Client comms: Send three quick emails: Capex timing, R&D expensing, International changes.
10. Documentation kit: Elections, placed-in-service proof, §163(j) workbook, §250/FTC mapping, CFC day-count log.
