• Exceptions: Some days may not count (transit, medical)

Permanent Home Test

Citizenship-Based Taxation

What is CRS?

The OECD Common Reporting Standard requires financial institutions to:

• Identify reportable accounts: Accounts held by non-residents
• Collect account holder information: Tax residency and TIN
• Report to local authorities: Annual XML submissions
• Automatic exchange: Information shared between jurisdictions

CRS Reporting Features

Account Classification

Domavia automatically classifies accounts as:

• Reportable: Non-resident accounts requiring disclosure
• Non-reportable: Domestic accounts or exempt entities
• Undocumented: Missing required information

Classification considers:

• Account holder tax residency
• Account type (depository, custodial, equity, debt, cash, annuity)
• Balance thresholds (typically $250,000 for pre-existing accounts)
• Entity type and controlling persons

Due Diligence Tracking

Track required documentation for each account:

The system alerts you when:

• Documentation is missing or expired
• Review dates approach (annual revalidation)
• Account holder changes residence
• Balance exceeds reporting thresholds

CRS XML Generation

Export CRS-compliant XML reports:

Generated XML includes:

• Message specification (reference ID, reporting period)
• Reporting financial institution details
• Account holder information per OECD standard

Individual CRS Obligations

As an individual with foreign accounts:

Self-Certification

You must provide your tax residency information to financial institutions:

• All tax residencies: List every country where you're tax resident

• Change notification: Update within 30 days of change

Impact of CRS

Your foreign accounts are automatically reported to:

This means:

• Compliance mandatory: Must report foreign income on tax returns
• Penalties for non-disclosure: Severe penalties in most jurisdictions

CRS vs FATCA

Key differences:

Many financial institutions report under both regimes.

Tax Optimization Strategies

Timing Income and Deductions

Strategic timing can reduce tax burden:

Income Acceleration/Deferral

• High-tax year: Defer income to next year if expecting lower rates
• Low-tax year: Accelerate income if expecting higher rates next year
• Moving countries: Time move to optimize income recognition

Examples:

• Delay business invoicing until January (defer income)
• Accelerate bonus payment before year-end (if beneficial)
• Sell property after establishing residence in low-tax jurisdiction

Deduction Timing

• Bunch deductions: Concentrate deductible expenses in one year
• Prepay expenses: Pay January expenses in December (if deductible)
• Charitable giving: Time donations strategically

Currency and Exchange Considerations

Multi-currency implications:

Foreign Exchange Gains/Losses

• Mark-to-market: Some countries require annual FX gain/loss recognition
• Realization basis: Others tax only on actual exchange
• Hedging strategies: Currency forwards/options may be tax-deductible

Currency Selection

• Earning currency: Where income originates
• Spending currency: Daily expenses
• Savings currency: Long-term holdings
• Tax currency: Currency of tax payment

Consider:

• Exchange rate volatility
• Transaction costs
• Tax treatment of FX movements

Investment Structure Optimization

Strategic investment structuring:

Asset Location

Place investments in tax-efficient jurisdictions:

• High-growth assets: In low-tax jurisdictions
• Income-producing: Where foreign tax credits available
• Real estate: Consider local vs. offshore holding

Timing of Realization

Strategic gain/loss realization:

• Capital losses: Harvest to offset gains
• Long-term treatment: Hold >1 year if beneficial rate
• Step-up basis: Time transfers for inheritance advantages
