Sooooo its march and we all need to fill out our taxes again. Im such a noob and its the first time it will get “complicated” cause of my Investments…
Basically I need help, could someone explain me how to do it I would be super thankful.
Do I need to put in all my ETF’s in the Wertschriftenverzeichnis or is it enough if I just put a Jahresbericht from Interactive Brokers and name it a Depot?
I’ve been doing that for years - but it probably depends… 
(Keep in mind accumulated dividends are not reported in IBKR’s reports, even though they are taxable).
I just need to get into it once and then it won’t be a problem anymore…
There is a function to get all the information on IBKR, dividends are also listed there.
(Performance & Berichte > Kontoauszüge > Aktivität > select time period > HTML → Ansicht)
Could you maybe provide me an example? maybe one for Wertschriftenverzeichnis and one DA-1?
As far as I know, you have to enter all purchases/sales. Then select the appropriate category (with/without withholding tax or DA1/R-US). You then enter your gross interest / dividends there. You can find the instructions for the DA-1 on your cantonal tax website. You can also obtain the DA-1 there.
the account statement only serves as proof of the information you have provided.
I have done both. I think different things are accepted as long as it’s done properly and with right information.
Method 1 -: in case your ETF portfolio only contains distributing ETFs, you use activity report from IBKR, put the total dividend income in one field , withholding tax in another field and in one entry you are done. I select Steuerauzug/Depot which is a selection in Zurich tax return
Method 2 -: list down each ETF as separate row and let tax software do the math
It all depends on which canton and what you actual portfolio consists of. If you have accumulating ETFs then you might need to account for those ETFs specifically or else it would end up being incorrect declaration
Things can become tricky when you also have Broker interest, Bond interest , etc …. In principle this income is not for DA-1, it’s for standard list of securities which is another section in tax return.
They finally responded to my support ticket and they agree that attaching the full statement for each position is a good workaround. I hope they’ve forwarded it internally to the development team and it will be fixed for next year.
Ich habe es bei einer Test-Steuererklärung versucht nachzuvollziehen und bin zum gleichen Resultat wie Sie gekommen, es muss offenbar tatsächlich für jede Position ein obligatorischer Beleg hochgeladen werden. Ihr Vorschlag, den Sammelbeleg für alle Positionen zu verwenden finde ich gut, ich hätte es ebenso gemacht.
Thank you so much for your answers!
My tax return is prepared by an tax advisor. I pass all my documentation to him and he gives me back what I have to submit.
Last year was my first year as a client of Interactive Brokers.
I am very clueless with all this tax stuff.
Is the “Form 1042-S” all that my tax advisor needs from Interactive Brokers?
Thanks
I’d give the dividend report (iirc it also have the end balance? If not also include that)
It’s a United States of America tax form to report income from (and possibly to) that country.
Do you file a U.S. tax return? Does it include the positions you’re holding and the trades you made during the year? No? Then it‘s probably not enough for your accountant in Switzerland to prepare your return.
Edit: most importantly, the IRS only state that it includes U.S.-sourced income. I take that as that it does not include distributions from other countries‘ companies or funds in other countries.
last year my whole activity in IB was:
As expected I see in “dividend report” the dividend I got from ATVI, but I don’t see the end of year balance in that dividend report, neither in form 1042-S.
What about the ATVI gain profit, currency exchange FOREX operations, and the appreciation in price of VWRA? isn’t they relevant at all for CH taxes?
No, I don’t
Just send him the following
Or full Activity report which has all of the above plus other stuff
Buying accumulating (high-yield bond or dividend) fund on 2 Jan and selling on 30 Dec =
tax-free profit.
Nice. 
Okay.
I should have clarified if one holds accumulating funds then process is a bit different
@CurlyChicken fyi if you hold accumulating ETFs, also add that info specifically
I assume you just switch to CHF before/when generating the custom reports for the tax declaration whatever the time of the year (i.e. not necessarily over the turn of the year)?
Yes. It is the base currency at the moment when you generate a report that is relevant.
My tax return is finalised. They accepted my self created Steuerauzug using Ictax info
Which canton was this? Did you include a QR code? How did you make it clear that the Steuerauszug was made by you and not a bank?
I used the manual upload option and there was no QR code.
When I say “manual steuerausug” - I am referring to a PDF file which I created myself. Using excel and print to PDF.
It just looks very similar to Data level in terms of information provided
I don’t know why I need to make it clear that it was made by me. It was made by me and I didn’t use any letter head of some bank etc. so it should be obvious I made it. I believe when some tax advisor makes such a statement, they must be doing similar math and putting it together
I didn’t really have to do this. I just did it because I wanted to try the approach.
Canton ZH.
