Reporting Currency
Definition
The currency in which the portfolio's gains losses and income are reported for tax purposes.
Why it matters
Tax authorities require gains and income to be reported in the local currency. FX movements between purchase and sale dates affect the taxable gain.
What most investors miss
The gap between what the term means and how it is usually applied.
They calculate gains in the holding's native currency. The tax authority may require the calculation in the reporting currency which adds FX gain or loss to the taxable amount.
How to read it
Convert transaction prices to reporting currency at the exchange rate on each transaction date. FX gain is part of the taxable gain in most jurisdictions.
Multi-account lens
How this term reads differently across brokers and accounts.
When holdings are held in multiple currencies across multiple brokers the FX calculation for each transaction must be done individually. Aggregating in the wrong currency distorts the tax position.
