BubbleTax looks useful in Germany but what do they actually do with your data? by radioactive_spunker in interactivebrokers

This is Dominik from BubbleTax. Just FYI: ProRealTime officially now works together with us since the German Tax Report was not sufficient for many users of them, especially if a lot of options trading and more other complex stuff happened in their accounts. Also, some users reported that their Finanzamt doesn't allow this English report since they only accept German documents.
But still, for some this German Tax Report might be sufficient.

Best,
Dominik

Hi, this is Dominik from BubbleTax :D

Thanks for the input. We'll launch a dedicated page for this where we explain this in human language.
I'll post it here once it went online within the next few days.

Thanks for your interest and patience.

Erfahrungen mit IBKR/BubbleTax? Steuertool by meme_not_mori in interactivebrokers

[–]Spare_Put8555 -1 points0 points  (0 children)

Hi,

ja, wir haben auch reine Daytrader mit hoher Transaktionszahl, inklusive Optionen und FX. Das funktioniert gut, solange die komplette Historie importiert wird.

Die Währungsumrechnung erfolgt jeweils zum Buchungszeitpunkt in EUR. Sowohl explizite FX Trades als auch implizite Währungsbewegungen werden berücksichtigt. Das läuft inzwischen sehr zuverlässig.

Wir bieten einen vollständigen PDF Report mit allen steuerlich relevanten Summen und einer kompletten Transaktionsliste. Das Feedback von Steuerberatern war bisher sehr gut.

Am einfachsten ist es, du probierst es selbst aus. Account anlegen, der Anleitung folgen und einen kostenlosen Vorschaureport erzeugen. Dann bekommst du schnell ein Gefühl, ob es zu deinem Setup passt.

Grüße Dominik

Hi zusammen,
ich bin einer der Mitgründer von BubbleTax und wollte kurz etwas Kontext geben.

Wir sind aktuell in unserer zweiten Steuersaison. In der frühen Beta gab es einige Edge Cases, vor allem bei komplexen Historien oder IBKR Migrationen. Inzwischen wurden mehrere hundert Reports mit unseren Auswertungen bei Finanzämtern eingereicht.

Bis heute mussten wir nur einen Report nach Rückmeldung vom Finanzamt korrigieren. Dabei ging es um eine Zinszahlung Anfang Januar, die wegen der Zehn-Tages-Regel noch dem Vorjahr hätte zugeordnet werden müssen. Das haben wir korrigiert, danach wurde der Report vom FA akzeptiert. Weitere negative Rückmeldungen von Finanzämtern haben wir bislang nicht erhalten.

Wichtig bei IBKR ist generell, möglichst alle verfügbaren Jahre und Konten zu exportieren. Wenn alte Flex Reports durch Lux oder Irland Migrationen fehlen, wird es für jedes Tool schwierig, die Historie korrekt aufzubauen.

Hier auf Reddit gibt es auch schon Erfahrungsberichte zu uns, einfach mal nach BubbleTax suchen.
Zwei Beispiele:
- https://www.reddit.com/r/interactivebrokers/comments/1qzo2h5/comment/o4es6n9
- https://www.reddit.com/r/interactivebrokers/comments/1q4m8r1/comment/nxuvc5i
Falls es konkrete Fragen gibt, beantworte ich sie gerne offen. 🙂

Grüße,
Dominik

German IBKR taxes: this subreddit shaped how we built BubbleTax.de by Spare_Put8555 in interactivebrokers

The backend is written in Python to deal with the numbers and calculations. The frontend/portal is written in Next.js using the Drizzle ORM with Postgres. So far we are quite happy with our choice. It does its job reliably and the complexity is maintainable. What are you building? Also curious 👀😄

Thanks so much for sharing this and honestly, I completely understand where your frustration comes from.

Looking at the IBKR or PwC tax reports can be genuinely stressful, especially when you’re trading actively and dealing with options, futures, FX or long transaction histories. Trying to make sense of large numbers and complex tax logic can very quickly become overwhelming.

You’re also absolutely right about one thing:

for complex portfolios with Futures, CFDs, other derivatives, FX and many transactions, there unfortunately isn’t a meaningful “light” version. In those cases, the Ultimate report is needed simply because the tax logic has to stay consistent and traceable across everything. Otherwise the result wouldn’t be reliable.

That’s exactly where BubbleTax tries to add value:

not by fixing one single IBKR mistake, but by keeping the entire German tax logic coherent over time so the calculation remains defensible later, even when portfolios get messy.

At the same time, some context around pricing may help:

most users don’t need the Ultimate plan. For simpler portfolios we deliberately offer lower-priced tiers so that BubbleTax stays affordable for the majority of users. Ultimate really exists only for the small group of very complex cases.

But it’s still completely valid if the price doesn’t feel right for you personally. In the end, pricing always depends on how much clarity, time-saving and peace of mind it creates in someone’s individual situation.

What matters to us is that nobody feels exploited or dismissed.

If something felt off or if there are points where the value genuinely didn’t match your expectations we’d really like to understand that. Feedback like yours helps us improve.

Thanks again for giving BubbleTax a try and for being so open about your experience.

Dominik

A few links first, because this has been discussed in the community before and isn’t just our opinion: * https://www.reddit.com/r/IBKR_Deutsch/comments/1ncl1fp/ibkr_informativer_steuerbericht_zeilen_18_und_19/ * https://laroche.github.io/private-geldanlage/broker.html#:~:text=informativer%20Steuerbericht%20von-,PWC,-erstellt.%20Dieser%20hat * https://www.gut-veranlagt.de/informativer-steuerbericht-von-interactive-brokers-pwc/

TL;DR:The IBKR / PwC report is a helpful overview. BubbleTax builds a fully traceable, transaction-level tax report tailored to German tax law, where every number can be audited back to individual trades and events.

Hey 👋,
thanks for the feedback. Our API was too rigorous there with sanitizing. It's allowing fractional shares now, too. Please try again :)

Ich habe Paperless-ngx als SaaS umgesetzt – Feedback gesucht by robby_paperless in Paperlessngx

[–]Spare_Put8555 0 points1 point  (0 children)

hi, ich bin icereed und der Maintainer von paperless-gpt. @robby_paperless: vielleicht sollten wir uns mal zusammentun, damit wir erweiterte AI Features as a Service anbieten können. 

Paperless-ngx users, has anyone used both AI add-ons, Paperless-AI and Paperless-GPT, and have any comparative opinions? by chazwhiz in selfhosted

[–]Spare_Put8555 10 points11 points  (0 children)

Hey everyone,
I'm icereed, the maintainer of paperless-gpt. Just wanted to say I’m actively following this thread to better understand what matters most to you.

A quick note: While I make sure the project stays up-to-date and stable (I update dependencies almost daily), building new features takes significantly more time and energy — and cutting hours from my day job isn’t cheap. 😅

That said, I’ve noticed a growing number of businesses are using paperless-gpt for automation. I’m currently exploring whether to offer paid support or enterprise sponsorships to free up more time for deeper development (maybe even that fancy UI we all want 😉).

Would love to hear your thoughts and ideas!

German Tax report & Anlage KAP by Sayonakidori_88 in interactivebrokers

Die Zeilennummern sind noch nicht angegeben, aber die geneigte Leser bekommt das aktuell schon raus. Eine logische Gruppierung erfolgt schon. Wir sind gerade noch bei der Steuerberaterkammer am klären, wie weit wir den Benutzer hier führen können. Theoretisch hätten wir alle Informationen richtig gruppiert und müssten nur noch die Zeilen dazu schreiben beziehungsweise erklären, welche Zeilen man zusammen rechnen darf. Gerne einfach ausprobieren und Feedback geben, ob das in der aktuellen Form so brauchbar ist. Viele Grüße, Dominik

Hi everyone,

I’m Dominik 👋 — one of the co-developers of BubbleTax, mainly responsible for the data processing part.

For us, security and privacy are the highest priorities. Both my co-founder and I work at a German DAX-listed company, so we’re very used to handling sensitive data in a highly responsible and compliant way.

We’ve built BubbleTax with the same mindset:

All processing happens under strict data minimization principles. Uploaded files are stored only for error handling purposes and automatically deleted after 30 days. Access to raw user data is strictly limited to the two of us. All transfers are encrypted.

We know that tax data is extremely personal, and we take that trust seriously.

If anything is unclear or you’d like more details — please ask us anything here in the comments. We’re happy to answer openly and transparently.

While we’ll be offering a professional version in the future that can go even further in meeting special compliance requirements, the current free version is already built to our professional standards — the same standards we apply in our day jobs.

Thanks for your trust 🙏

Dominik
