Create a modern, fresh logo for an online tax preparation company

File It.tax

We are an online / digital tax preparation company. We match end customers (individuals, not companies) with trained tax professionals / accountants who work with customers over the phone, email, skype etc to process their tax refund in a timely, efficient and ensure maximum tax refunds possible.

Nearly all marketing for this company will be web-based (facebook, linkedin, twitter, etc)

Typical customer for this company is upper middle class to upper class, who are sophisticated, smart with their money, etc. Therefore logo must convey sophistication, and not too cheap / flimsy.
Other attributes the logo should help convey: Trust, Professionalism, Integrity, Convenience

Logo should NOT including typical tax graphics (like dollar signs, Uncle Sam, Red White & Blue, etc. other cheesy / industry standard examples). Want this logo and brand to stand out from the pack.

The name of the company is File It, however I would like to include the webdomain .tax somehow creatively in the logo.

Very excited about what the community at 99 design will delivery. I will be very responsive throughout the entire contest and provide regular, detailed feedback along the way.
