Wealth Estate Tax Workflow Base

Wealth / Estate / Gift / Property Transfer Tax Workflow Base v0.1

What this file is

Tier 1 workflow base for transfer-on-death, gift, annual wealth, and property purchase tax skills.

Section 1 — Audience and assumptions

This base covers a family of related taxes triggered by:

• Holding — annual wealth tax
• Transfer at death — inheritance / estate tax
• Inter-vivos transfer — gift tax
• Real estate purchase / transfer — property transfer tax / stamp duty

This base assumes:

• The taxpayer (or their representative) is preparing an accurate inventory
• Cross-border situs rules require multi-jurisdictional analysis
• A credentialed practitioner signs off before filing or transfer

Section 2 — Universal lifecycle

Step 1 — Identify the chargeable event

Event / Tax(es) potentially triggered table ([T1])

Event	Tax(es) potentially triggered
Annual reference date (31 Dec typically)	Wealth tax (Spain, Norway, Switzerland, Argentina, Colombia, Uruguay, France IFI, NL Box 3)
Death of holder	Inheritance / estate tax (DE, FR, ES, IT, NL, BE, UK, US, JP, KR)
Gift / lifetime transfer	Gift tax (DE, FR, ES, IT, NL, BE, UK, US, JP, KR)
Real estate purchase	Property transfer tax (UK SDLT, DE GrESt, FR DMTO, IT registro, ES ITP/AJD, NL OB, SG BSD+ABSD, HK AVD)

Step 2 — Determine personal scope

• Personal scope for wealth / estate / gift — Tax residence / domicile / long-term residence (UK from April 2025) of taxpayer / decedent / donor; worldwide assets if resident; local-situs only if non-resident ([T1])
• Personal scope for property transfer — Purchaser's residence affects surcharge (UK 2% non-resident; Singapore ABSD 60% foreign; Canada NRST 25%; Australia state surcharges 7-8%); property's situs determines primary tax ([T1])

Step 3 — Inventory all assets

• For each asset, document — Class (real estate, listed shares, unlisted shares, bank deposit, debt instrument, private equity, art / collectibles, crypto-asset, pension rights, life insurance, business interest); Location (situs per jurisdiction's rules); Valuation date; Valuation method (cadastral value, FMV, latest transaction, IFRS book value, professional appraisal); Ownership share ([T1])

Step 4 — Apply valuation rules

• Spanish ISD / wealth tax — Cadastral value for real estate; "valor real" elsewhere ([T1])
• French IFI — Market value with 30% discount for primary residence (wealth tax) ([T1])
• German Erbschaftsteuer — Bewertungsgesetz fair market value with specific business property mechanics ([T1])
• UK IHT — Open market value at date of death ([T1])
• US estate tax — Fair market value at date of death OR alternate valuation date (6 months later, electable) ([T1])
• Italian successioni — Cadastral value × multiplier (110 for first home, 120 for second, etc.) ([T1])

Step 5 — Deduct liabilities

• Deductible liabilities — Mortgages secured on the relevant asset; Funeral expenses (US, UK estate); Administration expenses; Outstanding tax liabilities; Loans where foreign-bank-debt restrictions apply (Spain ISD, Uruguay) ([T1])

Step 6 — Identify beneficiaries and apply relationship rules

• Beneficiary relationship categories — Spouse / civil partner / cohabitant; Direct descendants (children, grandchildren); Direct ascendants (parents, grandparents); Siblings; Other relatives within a defined degree; Unrelated. Each relationship has distinct exemptions and rates (Germany Class I-III; Spain Group I-IV; France direct line vs collateral). ([T1])

Step 7 — Apply exemptions and reliefs

• Common reliefs — Marital deduction (US unlimited; UK unlimited for LTR spouse; EUR 500k Germany); Habitual residence exemption (Spain national EUR 300k); Family business / Pacte Dutreil 75% (France) / Verschonungsabschlag 85-100% (Germany) / BPR 100% (UK); Agricultural property relief (UK APR; various national reliefs); Charitable beneficiary deduction; Disabled beneficiary supplementary allowance ([T1])

Step 8 — Apply rate schedule

• Rate schedule forms — Progressive by amount (US estate 18-40%; French succession 5-45%; German IHT 7-50%); Flat by class (Italian successioni 4% / 6% / 8%); Regional variation (Spanish ISD by CCAA; Swiss canton) ([T1])

Step 9 — Apply caps and integration

• Caps and integration rules — Spain: combined IRPF + IP + Solidaridad capped at 60% of IRPF base; France IFI: capped at 75% of prior year income; US: estate, gift, GST share a unified credit; UK: 7-year cumulation rule (lifetime transfers within 7 years before death come back into estate) ([T1])

Step 10 — Compute and apply foreign tax credits

• Foreign tax credit rule — Treaty article 22 (wealth) or estate / inheritance tax treaties (rare; ~15 bilateral). Unilateral credit usually available for same asset taxed twice. ([T1])

Step 11 — Filing and payment

• Filing and payment components — Identify filing form per regime; Filing deadline (typically 6-12 months from event); Payment terms (instalments for family businesses); Currency translation rules; Documentation index ([T1])
