I'd like it if we could take up other, simpler models of sorting out income tax but I use software out of this pool† every year and its served me just fine:

† usually StudioTax. I donated to them last year. It's not pretty software but it's effective and easy to use. https://www.studiotax.com/en/

"Our business model is similar to that of a street performer. You can use and enjoy our software and later decide if the experience was worth it and you can afford a donation. However, based on many users’ feedback, you should be wary of recent free offerings from big commercial organizations. To use our previous analogy, they are big circuses that send their clowns out to the street to attract unsuspecting customers to their tents and pressure them in paying for their overpriced shows."
