I asked my employer to give me an income statement, which they issued in ADVANCE until the end of July (including the salary I should get next week). I got a closing statement from the bank (including interests gained, which is what the Steueramt wants), a closing statement from my Health Insurance (primes are deductible) and I printed from my bank's online e-banking system my wife's payments to the AHV Kassa (which you can also deduce). I took that along with the 2009 Steuererklärung forms I got at the City Hall and gave it ALL to an accountant, who will do the Erklärung for me. They will send it to the Steueramt for me, and the Steueramt will send the final due payment lump sum payment slips to my "Vertreter", who is a colleague at work who will just mail it to me. Since I'll keep my bank account open I will be able to pay via e-banking in a few weeks, when everything collides into a big boooooom !
