Maybe not, yet. But over a period of gradual improvement, it may offer something unique to certain niche. e.g beginner users, who would prefer a tax calculation tool with a clear and easy to understand step by step guide, followed by some tax related advise etc (something similar to what you've recommended). Thanks.
Points noted. It's the initial version of what I wanted to build. I'll add more features gradually as I get some input/suggestion from the users. Thank you.

Yes, most of the visitors come from organic searches. Not necessarily, because a tool based site will be competing mostly with other tool based sites, with little or no text content. So other factors may be more important e.g bounce rate.
