In the second part of the eFisc-Thurgau guide, we have completed the following sections of our Swiss tax return (for the canton of Thurgau): real estate, professional deductions, debts, pension provision and insurance.

Let’s move on to the other categories, and in particular to the most interesting part, our stock market investments!


Step 1: Donations

Entry of donations and gifts during the fiscal year with indication of purpose

All bank accounts must be declared. Use your bank’s tax certificate.

Be sure to save the form explicitly (so that you don’t lose the information you entered).


Step 3: Securities

We assume you have this portfolio of stock market investments:

Most of the data is taken over automatically. All you have to do is specify:

This form has no automatic saving. Always choose Apply and close

US securities with withholding tax are part of the DA 1 form if required.


Step 4: Electronic tax statement

If your bank offers an electronic tax statement, the data it contains can be transferred automatically. This is done via the tax barcode and requires an electronic interface between the bank and the tax system.

If the electronic tax statement is empty, it doesn’t mean that the tax return is wrong. It simply means that there is no automatic interface, or that there has been no electronic delivery by the bank. In this case, the field remains empty and the information must be entered manually.

And for the record: the tax barcode is never manipulated or entered by the taxpayer himself. It is either transmitted automatically by the bank, or is not available at all.


Step 5: Other assets

Form 'Motor vehicles' to declare make, purchase price, year of acquisition and tax value

The value of the vehicle can be written off each year.


Step 6: Conclusion

Relevant in case of real estate or income in other cantons or abroad.

Remarks

Here you can add comments for the tax authorities, if there is anything that needs further explanation.

Submission

Check everything again with your spouse. Then you can either submit the tax return electronically, or print it out, sign it and send it by post. You can also drop the documents directly into the tax authorities’ mailbox or hand them in.

After a few weeks or months, you’ll receive the final tax assessment. Depending on the result, you’ll either receive an invoice or a refund.


Congratulations, you’ve completed your tax return.

And as always, if you find any other (legal!) tax optimization ideas in the screenshots above, don’t hesitate to let me know.



As usual, I only write and review things that I use in my personal daily life, or that I trust.
