What we’re seeing in the tax landscape

Four forces reshaping the modern tax function.

Tax is no longer a back-office filing function. CFOs, tax directors, and audit committees are being asked harder questions, on tighter timelines, with smaller teams. These four trends keep coming up in every conversation we have with the office of the CFO.

01

AI is no longer optional in tax

Generative AI is moving tax work from manual to model-driven: data aggregation, compliance monitoring, scenario modeling, and audit readiness. Tax departments that wait are getting outpaced by the ones already deploying it.

02

Regulatory scrutiny is intensifying

Today’s political and business climate places heavier regulatory pressure on tax consulting, income tax filings, reporting, and disclosures. Material weaknesses and restatements tied to tax are landing in the headlines.

03

R&D relief is back, with deadlines

The OBBBA Section 174A retroactive election lets small businesses recover R&E costs capitalized between 2022 and 2024. The July 6 election deadline means tax teams are scrambling to model, file, and amend in parallel.

04

Multi-jurisdiction complexity is the norm

SALT nexus, indirect tax, and international transfer pricing now matter for almost every growth-stage company. Where you sell, where you hire, where you ship: each opens a tax footprint that has to be modeled.

Why CFGI in Tax

Big-4 pedigree. Boutique attention. No audit conflicts.

The CFGI Tax practice was established by leaders with decades of Big 4 and in-house tax experience, then built around a boutique delivery model where senior partners stay on the engagement.

Strategy and execution, under one roof.

  • Sat in the seatsSenior tax professionals with experience as VPs of Tax, tax directors, and Big 4 partners. Practical, not theoretical.
  • End-to-end lifecycle coverageStart-up, IPO, and public company tax needs handled by one team. No handoffs between firms as you scale.
  • Flexible deliveryLimited-scope projects, interim staffing, or fully outsourced managed services. We adapt as the team and the calendar shift.
  • AI-native tax thinkingWe build AI assistance into provision, compliance, scenario modeling, and audit readiness. Practical, not slideware.
  • No audit restrictionsFree from audit independence constraints. The firm that runs your audit cannot do this work alongside it.
Where tax teams get stuck

Six questions every tax leader is already getting asked.

Is our auditor also doing our tax work?

If the firm running your audit is also preparing your provision, you have independence risk. The closer you get to going public, the harder that conversation becomes. The fix usually has to happen before the IPO clock starts.

Are we leaving R&D credits on the table?

If you have R&D spend, you likely have federal and state credits available. Even with NOLs, the credits can offset state taxes, carry forward, or surface during M&A diligence. Most companies are not maximizing them.

What is our actual SALT footprint?

Where you have sales, employees, inventory, and offices each creates a nexus question. Sales, use, and indirect tax exposures often surface only during diligence, when leverage is gone. A formal nexus and taxability study closes that gap.

Can our tax data actually be trusted?

If the tax team spends more than 30 percent of cycle time preparing data, the issue is upstream. Spreadsheets as the primary system of record, ERP gaps, and missing tax data requirements in past implementations all show up as material weakness risk.

Do we have an NOL ownership-change problem?

If the company has net operating loss carryforwards in the United States, auditors may require a 382 calculation. Ownership changes can limit or write off available NOLs, and most companies do not see it until M&A diligence forces the issue.

Are we ready for the next transaction?

Buy-side, sell-side, carve-out, reverse merger, IPO: each has tax implications that move the deal economics. Tax purchase accounting, structural diligence, and post-close integration all benefit from being in the conversation before the LOI.

Latest tax insights from CFGI

Two perspectives shaping tax decisions right now.

Insight, March 2026

The intelligent tax department

AI is no longer optional in tax

What the article covers

CFGI’s Kevin Murawinski walks through the practical applications of AI inside the tax function: data aggregation across siloed systems, intelligent compliance monitoring, scenario modeling and what-if analysis, audit readiness, and natural-language interfaces that surface answers without writing a SQL query.

Why it matters now

Tax departments that wait are getting outpaced. AI is closing the gap between strategic intent and execution, and the talent equation is shifting in favor of teams that adopt it early. The piece ends with concrete starting points for tax leaders who want to move from pilot to production.

Highlights

  • Data aggregation patterns that connect ERP, provision, and compliance.
  • Scenario modeling for legislative change, M&A, and global expansion.
  • Audit readiness automation that surfaces gaps before the request hits.
  • A talent and operating model view: AI as a team multiplier, not a replacement.
Insight, May 2026

Section 174A retroactive R&D relief

July 6 deadline for small business election

What the article covers

CFGI’s Bill Barnes and Kevin Murawinski break down the OBBBA Section 174A retroactive election for small businesses. The new election allows recovery of domestic R&E costs capitalized between 2022 and 2024, with eligibility tied to the Section 448(c) gross receipts test and interaction with the Section 280C credit calculation.

Why it matters now

The election deadline is July 6. Companies under the 31 million gross receipts threshold need to model the cash impact, evaluate the Section 280C interaction with R&D credits, and decide whether to amend prior returns or accelerate deductions.

Highlights

  • Section 448(c) gross receipts eligibility test with the 31 million threshold.
  • Section 280C interaction with R&D credits, including the trade-off math.
  • Amended return mechanics for 2022, 2023, and 2024 tax years.
  • Cash-flow modeling tied to the July 6 election deadline.
