4.25%? Is it really that high?!
So if I understand correctly, for example:
Meaning you get CHF44.6k extra “income” that you have to pay tax on each year? If you’re a high earner that could be CHF15k+ in extra taxes right?
Not quite. These 44.6k will be added to your income to compute the income tax rate, but will not be taxed. The same happens for the wealth tax.
So for example, if your normal income is 200k and your total wealth excluding this property is 2M what will happen is:
The idea is that, if the other country would do the same trick - it would be perfectly fair and not allow you do avoid tax progression by splitting your earnings among different countries
Ok, planning to file taxes later – after all bugs are sorted out – is like making a New Year’s resolution.
After 10 days or so I cave in.
How can you tell?
I started on the weekend and when trying to continue this morning, the system first wouldn’t accept any more attachments. Called the technical support, they said they’re aware and will push a new release on Wednesday. Support says I can still enter all the data, but add the attachments only after the new release.
Ok, minor glitch, I guess. I take a coffee break, log back in to further fill things out, just without attachments.
Well, I intend to log back in.
Sigh.
Edit: In fairness: site works again flawlessly this evening, I can even upload attachments. 
Probably a stupid question, but is it really necessary to put all trades in the declaration? Isn’t it enough to state what we have, which dividends/tax were paid, and that’s it (as passive investor who didn’t sell any stock)?
Asking this as I’m a bit lazy. But depending on the answer, I could go on with the second question… How can we modify a declaration if it’s already been submitted and we need to add things, eg… Trades?
Asking for Vaud if that even makes a difference
For ZH that‘s enough.
The french speaking cantons I think are quite a bit more strict on stuff like this.
I never put any details of transactions in Vaud, last year was the only time they asked for more details and I just sent a pdf from IBKR and that was fine.
It depends. Some cantons it is enough to put a summary and attach the schedule.
In other cantons, you have to enter line by line as they do not accept market values but use their own tax values for securities.
How do you avoid putting in all detailed transactions for zurich? It complains otherwise. Does it let you submit the declaration regardless?
If I have a zero position end-of-year and had no dividends I just leave it out. It is not relevant for taxes.
If somebody asks I provide the complete data from IBKR, even it is not needed for taxing but maybe to explain capital gains. They did never ask however until now. I adhere all the rules for not being a professional trader anyhow.
it only warns, you can ignore that IIRC
I had a call with the Vaud tax office and they said it should be fine to skip the transactions as long as the end of year part is filled, as well as dividends and taxes. On Vaud Tax we fill each fund’s details (isin, etc) and under the summary there’s a “add transaction” button, which I simply didn’t touch. It went well.
And if anyone wonders, we can edit the declaration after posting it for a few days. We need to go through the login again, start a new declaration and import the save file, do the modifications and publish it again, then a message will warn us it’d overwrite the previous one. Confirm and that’s it.
Everything entered now (even with a slow ZH PrivateTax site today).
Will double-check things tomorrow and submit afterwards.
After comparing the compact summaries – Steuererklärung Kompakt – for 2023 and 2024, we have about 5% additional taxable income and about 16% additional taxable wealth.
This results in about 10% additional total tax.
Progression is a bitch.
This means you made very good stock pick in 2024. Congrats ! 
What I consider to be less than ideal is that in a case, where they correct my tax declaration, it still displays online the version that I originally submitted (ZHprivateTax).
This happened to me last year, so the comparison 2023 vs. 2024 is incorrect in my case.
Anybody had the same happened to them?
Actually the worst is the so called “warm progression”. We pay about 2.5 billion too much because of warm progression which is not fair. If all income progresses they should correct for warm progression the same way they do for cold progression!

It looks like they updated their ICTax data, the dividends I was missing are there now.
US9219438580 still missing for me.
Weird, I see the dividends if I search for it. They don’t roll it out at the same time for all users perhaps?
Same version here. Not sure why it differs (the demo account also manages to find it)
