Tax optimisation for ETF investing [2024]

Loans incl. mortgage are based on the interest deducted in portion of asset value. The wealth management fees he mentioned are based on investment income.
Eventually, both deductions are combined.

Again, thanks so much. Now I have to fire up my investment spreadsheets and redo my “are US ETFs worth it” calculations.

Yes, the ratio of the tax value of DA-1 assets to the total taxable assets is what’s used to distribute deductions (Steuerwert DBA-Titel : Wert Total Aktiven).

Seems correct to me, assuming 16.5% is the tax rate and there are no other taxable assets.

The 16.5% was just example from the comment above. Thanks for clarifying the calculation

Correct for deducted interests, not correct for asset management costs that were used in the example above.

At least for the tax year 2019 in ZH, both types of deductions were handled the same way as “Schuldzinsen u. Unkosten”. It’s possible something changed since then or not all cantons do it the same way, though.

Right, it used to be. Just checked my old documents.
2019 was a long time ago :slight_smile:

It was changed (or rather specified) with the law on tax reform and AHV financing (STAF; 18.031) in 2019, effective since 2020.

Same as my experience from tax declarations in ZH from 2020-2023.

Good morning,
probably stupid question, excuse my ignorance.
Let’s say I receive 850 CHF of dividend from VT (1000 CHF gross - 15% L2TW) and that I have a marginal tax rate of 20%, to calculate the actual taxation on the dividend this calculation is correct:

1000 CHF are declared and taxed at 20% (marginal tax rate) = 1000*0.2= 200 CHF
The following year (if I fill out the DA-1 form) they deduct 15% of the L2TW from my total taxes so I get back 150 CHF.
Total lost in taxes = 200-150 = 50 CHF

Net dividend yield:
850 CHF received - 50 CHF taxes = 800 CHF

Total taxes on net dividend received = 50/850*100= 5.88%

So in my spreadsheet to consider the net dividend yield I enter -5.88% on net received.

While reasoning on the gross dividend the total taxes correspond to your marginal tax rate = 1000 CHF * 0.2 = 200 CHF, because the 15% of L2TW is recovered.

Did I interpret everything correctly or did I miss something?

That looks right, but that’s a fairly odd way to look it it :slight_smile: Normally the denominator is always the gross dividend.

Thanks, my goal was to make sure that the only taxes paid on the dividend are actually those related to the marginal rate and no others.

From the pespective of a Swiss investor, which is the best funds domicile for a fund holding European stocks, Switzerland, Ireland, US or doesn’t it really matter which one?
