Practice / 03TAX OPTIMIZATION

Pay the tax you owe. Not a point more.

International tax structuring for digital businesses doing €1M–€100M+. Built to survive audits. Signed by lawyers — not sold by offshore brokers. We work alongside your Big-4, not around them.

Defensible on paper. Defensible in an audit room. Defensible on exit diligence.

Who this is for

You're in the right place — probably.

  • 01

    Your group does €1M–€100M+ revenue across two or more countries.

  • 02

    Your effective rate is north of 25% and your accountant says that's 'just normal.'

  • 03

    You've heard 'Dubai / Malta / Delaware' from every peer and don't know which advice is real.

  • 04

    You have IP worth migrating, or remote employees in jurisdictions you can't name.

  • 05

    You're 12–24 months from an exit and worried about the tax hit on sale.

  • 06

    If you're looking for a 3% rate from a PO box in a tax haven — we're the wrong firm.

If you want to legally keep 8–15 points you're currently overpaying, keep reading.

Cost of Getting It Wrong

The four ways this goes sideways

Not hypotheticals. Each of these is a file we've closed for a client who found us late.

Scenario 01
Trigger

Transfer pricing, unflagged.

Consequence

Intercompany royalty flows set by your 2019 accountant. No contemporaneous documentation. Finanzamt opens a file.

Retroactive adjustment
€1.4M–€3.8M
Scenario 02
Trigger

IP migrated too late.

Consequence

You wait until Series B to move the IP out of the operating entity. Exit tax triggers on market value, not book value.

Avoidable cost
€2M+
Scenario 03
Trigger

R&D credits forgotten.

Consequence

Four years of SaaS development. No claim filed. Statute of limitations closes windows one year at a time.

Lost credits
€400K–€900K
Scenario 04
Trigger

Audit lost on documentation.

Consequence

Not because the structure was wrong — because nobody could produce the board minutes, benchmarking study, or intercompany agreements.

What We Do

Six things. Done right. Documented for audit.

International tax structuring

Your holding chart benchmarked against your revenue, geography, and exit horizon. We model three scenarios, you pick the defensible one.

  • Treaty-driven entity placement (not 'tax haven' placement)
  • Substance tests stress-tested before implementation
  • 5-year forward model including exit

Transfer pricing

OECD-compliant intercompany pricing, documented the way auditors read it. The goal is boring files that close fast.

  • Master file + local file + CbCR where triggered
  • Benchmarking studies with live comparables
  • Advance pricing agreements where volume justifies it

R&D tax credits

Most SaaS founders leave 4–7% of engineering spend on the table. We file, defend, and document — not just generate the paperwork.

  • UK R&D, French CIR, German Forschungszulage, US §41
  • Technical narratives written by people who read your repo
  • Retroactive claims within statute windows

Holding & IP strategy

Where your IP lives determines 30% of your effective rate and 100% of your exit math. We get this right once.

  • Ireland / NL / LU / CY / MT — honest comparison
  • CFC rule modeling (GILTI, ATAD, Hinzurechnungsbesteuerung)
  • IP migration with defensible valuation

Withholding tax + treaty planning

Royalty, dividend, and interest flows structured to use treaty rates instead of statutory ones. Documentation that survives beneficial ownership challenges.

  • Treaty network mapping across payment flows
  • Beneficial ownership + principal purpose test defense
  • DAC6 / MDR reporting where required

Exit planning

The structure that was right at founding is wrong at exit. We fix it 18–36 months before the bankers are in the room.

  • Pre-sale restructuring without triggering exit tax
  • Participation exemption qualification
  • Seller-side tax diligence pack
Coverage

Where we structure, not just advise.

Flagship jurisdictions with full in-house depth. Active structuring across 12 more. Treaty and advisory coverage on request. One invoice, one point of contact.

How We Work

Four phases. Scoped upfront. No hourly fog.

A typical structuring mandate runs 3–6 months from first call to steady-state. Quarterly reviews thereafter.

PHASE 1Week 1–2

Discovery & map

Full read of your structure, filings, intercompany agreements, IP position. We produce a risk heatmap before proposing anything.

PHASE 2Week 3–6

Structure design

Three scenarios modeled: aggressive, balanced, conservative. Rate, substance cost, audit exposure quantified for each. You pick.

PHASE 3Month 2–6

Implementation

Entity formation, IP migration, intercompany agreements, substance build, rulings where available. Single point of contact throughout.

PHASE 4Quarterly

Ongoing review

Legislative change tracking, documentation refresh, pre-audit readiness. Because the rules change twice a year.

Case Files

Two files we closed.

Anonymised by client request. Every number is real.

Challenge

Operating company in Germany, IP in Germany, customers in 14 countries. Effective rate 31.2%. Founder was a German tax resident with no plan for the next raise, let alone exit.

Approach

Migrated IP to a substance-backed Irish entity over 9 months — local directors, office, board meetings, contemporaneous valuation. Restructured intercompany royalties with OECD-compliant benchmarking. Filed 4 years of retroactive R&D credits across DE / FR / UK. Founder relocated to Portugal under NHR with full audit trail.

Outcome

Post-structure effective rate 19.8%. Retroactive R&D recovery €1.1M in year one. Annual cash improvement ~€1.9M at current ARR.

They told us which of the three options would survive an audit. The other two firms we talked to just pitched the cheapest rate.

19.8%post-structure ETR (from 31.2%)
Challenge

Six operating entities, Cayman holdco that looked great in 2018 and terrible to a German strategic buyer in 2025. 14 months before LOI. Baseline sale structure would have cost the sellers ~€9.4M in tax leakage. The buyer had flagged the offshore layer in early diligence.

Approach

Collapsed the Cayman layer into an EU holding (NL) qualifying for participation exemption. Repapered intercompany flows. Closed a formal ruling with the German tax authorities confirming no exit-tax trigger on the migration. Built the seller-side tax diligence pack before the buyer asked.

Outcome

Clean participation exemption on close. Seller-side tax cost reduced by ~€9.4M vs. baseline. Buyer's tax counsel asked three questions on the restructure and moved on.

We walked into diligence with a clean pack. The buyer's tax counsel asked three questions and moved on.

We work alongside your Big-4.

EY / PwC / KPMG / Deloitte — they stay.

We've co-piloted on 60+ mandates. You keep your accountant. We give them a better chart to work with.

Flat fees. Scoped upfront.

FAQ

What CFOs actually ask on the call.

No legalese. If the answer is 'it depends,' we'll tell you exactly what it depends on.

Accountants file returns against the structure you already have. We design the structure. Most of our clients keep their accountant — we just give them a better chart to work with.

Structure review: flat €12K–€25K depending on complexity. Implementation: scoped per project, typically €40K–€180K. Ongoing retainers from €2,400/mo. You see the number before we start.

Discovery and design: ~6 weeks. Implementation: 2–6 months. Most clients see rate reduction in the first full fiscal year post-implementation.

No. They stay. We handle the advisory and structuring work Big-4 firms either won't sign off on or price at 4x. We've co-piloted with EY, PwC, KPMG, and Deloitte on 60+ mandates.

Bring your last filed return and your current entity chart. We'll tell you — on the call — whether there's 8+ points to recover or whether your current structure is already tight. No pitch.
