Quantic for expat and multi-country investors
Several currencies, withholding tax at source, and official daily exchange rates dated to the day each thing happened.
Invest across borders and the headline yield stops being the number that matters. A US company keeps a slice of your dividend before it reaches you, your broker reports in one currency while you file in another, and the exchange rate that counts is the one from the day of the payment — not today's.
Quantic estimates withholding from where each holding is based and where you are tax resident, and shows income both gross and net, grouped by paying country, so you can see which part of your income is being taxed away before it arrives. Currency conversion uses the European Central Bank's official daily reference rate for the date of each event, stored as a dated series rather than applied at today's rate. The tax report assembles a year out of your own ledgers in the two sections a declaration asks for. Positions are held in their own currency throughout, and the interface is available in seven languages.
The dividends section works wherever you are tax resident, but the disposals section is modelled for Spain only so far, including its two-month repurchase rule. The report calculates no tax — it is the input to a declaration, not the declaration — and it is a beta feature on the Pro tier. Withholding rates are estimates from the country of the holding, not from your treaty position.

Key terms
- Withholding tax
- When you own a foreign stock, the company's home country usually skims a percentage off each dividend before it reaches you — say 15% on US shares. Quantic estimates this from where each holding is based and your tax residence, so your income reflects what actually arrives. It's the tax withheld at source only — not any tax your own country adds, nor amounts you can often reclaim or credit back under a tax treaty.
- Gross vs. net
- Gross is the dividend before tax; net is what actually lands after withholding tax. Quantic tracks both.
- ECB reference rate
- The euro exchange rates the European Central Bank publishes once each working day. EU tax administrations accept them, which is why Quantic's tax report converts foreign dividends and sales at the rate for their own date rather than at today's rate or your broker's. There is no rate on weekends or holidays, so the report uses the most recent one published before that date and tells you which day it used.
- FIFO (first in, first out)
- When you sell part of a holding you bought in several goes, FIFO says you sold the oldest shares first. Most of Europe taxes securities this way, so it decides what those shares cost you and when you acquired them. Quantic carries your holdings at average cost — the better measure of how a position is doing — and uses FIFO only in the tax report, which is why the two can show different figures for the same sale.
- Two-month rule
- A Spanish rule: if you sell at a loss and buy the same security back within two months either side, that loss is not deductible this year. It is not lost — it attaches to the shares you bought back and comes due when you eventually sell those. The window is a year, not two months, for securities not listed in the EU. It exists to stop people booking a loss and immediately buying back in.
