Websites for a tax return
Hi everyone, I have seen posts like this around but have a slightly different situation. I am a current resident in Germany with an EU passport. I tried to register for the ELSTER portal but they only accept the letter identification and my address doesn't have my surname on the door so I am worried that the letter will never get delivered. Are there any free or cheap websites (under 40 eur) that I can use to fill out my tax return that will submit it for me? I don't want to pay the fee and then realise I still don't have access to the portal where I should submit it.
PS: I moved to Germany in 2025 and had to fly here 2 times before to do appartment viewings and to physically submit documents for my employer, should I also include the flight prices in my tax return or are these not covered?
