What we need from you

Some things no tool can derive from a broker export — they simply are not in it. In those cases capi.tax deliberately does not guess; it asks you. This page shows where your input is needed and why it changes the result.

The rule behind it: better a visible prompt than a quiet assumption inside a tax figure. Everything you add is recorded as its own traceable entry with a reason, and you can read it back in the audit trail.

Setting the fund type

Whether a fund counts as an equity, mixed or property fund decides the Teilfreistellung — the share of your fund income that stays tax-free from the outset (30 %, 15 %, 60 % or 80 %). That German classification appears in no broker export: Interactive Brokers and Tastytrade do not know it.

So you assign the affected securities to a category yourself — shares, investment fund, mixed fund or property fund. What counts is the fund's prospectus (Anlagebedingungen), not its composition on a single day. Without your input, capi.tax does not fall back on a silent assumption; it flags the gap.

Adding a missing opening trade

If you sell something in 2025 that you bought in 2024 but only upload the 2025 export, the sale has no counterpart. FIFO cannot assign any cost basis — the trade stays in the audit trail as unmatched and is left out of the totals.

There are two ways out: choose an export reaching back to the opening — or add the missing opening position yourself (quantity, amount, date). After that capi.tax includes the trade normally.

Adding an individual lot

Similar but more general: if a holding came from a transfer from another broker, capi.tax knows neither its purchase date nor its cost basis. You can add both as a manual lot — the acquisition date matters especially, because it drives the FIFO order and, for older holdings, their grandfathered status.

What capi.tax cannot do for you

A few things stay outside the tool on purpose:

• Redemption prices for the Vorabpauschale. Broker data does not carry a fund's year-start and year-end value; those come from the fund company.
• Return of contributed capital. Whether a US company's "return of capital" payment qualifies as an Einlagenrückgewähr cannot be decided automatically — there is a separate procedure for it at the Federal Central Tax Office.
• Your allowance and personal situation. The Sparer-Pauschbetrag, the Günstigerprüfung or church tax depend on you, not on your portfolio. That is why capi.tax shows the taxable base rather than your finished tax bill.

Why this is a good thing

Each of these is a point where an automated tool could guess — and where a wrong guess travels silently into a number you report to the tax office. capi.tax makes the gap visible instead and leaves the decision to you, with a reason that still makes sense later.

capi.tax prepares your data and is not tax advice. Please review the figures and ask a tax advisor (Steuerberater) about your personal situation.
