The clients of the Tax Law Office of David W. Klasing have a long history of sleep problems when faced with incredibly emotional and high-stakes scenarios like the following:
Fortunately for my clients, my staff and I have become quite adept over the years in engaging in damage control, at worst, and, ideally, taking the offensive against the taxing authorities. At the same time our tax professionals endeavor to minimize the stress that accompanies high-stakes tax problems which can often threaten a client’s financial well-being and, quite often, their very liberty.

About our Tax Law Firm
The tax attorneys at The Tax Law Offices of David W. Klasing believe that every client’s individual needs should be paramount and front and center to each engagement. We will never put our firm’s inherent need to make a profit, so that we can feed our families, ahead of our clients’ needs for effective, zealous, aggressive, creative, efficient and loyal legal tax representation, accounting and tax compliance services. For example, at any of our California locations of our tax law firm we will never counsel a client towards litigation where a fair settlement can be reached without it out of our own self-interest.
Moreover, we will never take a client’s matter where we do not believe the client will be better off for having engaged us from the outset. We will protect our clients from themselves when necessary. We strive for 100% client satisfaction. We believe that our billing should be transparent and therefore we bill on an hourly basis at the billing rate of the tax lawyer or CPA professional providing the service and always where possible push a client’s work down to the lowest billing rate for the service provided within our organization. We are active members of the community in Los Angeles and Irvine and members of Orange County Bar Association.

*POLICY ON SCHEDULING A MEETING AT ONE OF OUR APPOINTMENT ONLY SATELLITE LOCATIONS:
David W. Klasing ESQ., MS-Tax, CPA, and the highly qualified and experienced staff of Attorneys, Certified Public Accountants and Enrolled Agents he has assembled, have a very unique and hard to find skill set. Over the past several years, the demands for the firm’s services have proven to extend to all of Southern California and beyond. Since the opportunity costs involved with traveling to one of our satellite offices, where a client misses an appointment for any reason are astronomical, we require the client to first personally attend either a one hour reduced rate initial consultation in Irvine, California, or virtually via the internet through Go-To-Meeting software, or by phone. Thereafter, if needed, we will book an appointment at one of our appointment only satellite offices.
Will it cost me more to hire the Tax Law Offices of David W. Klasing, who’s main office and the vast majority of the firm’s staff is located in Irvine California but a Satellite office is close to my location, as opposed to a local company?
To enable our clients and potential clients to be indifferent on this very valid concern, we employ the following policies that enable our firm to affirmatively answer with a resounding “NO” to this question.
Policy 1: Where possible and deemed advantageous, we will attempt to resolve your issues by correspondence with the taxing authorities and where not possible we will attempt to relocate your issue to a local office of the appropriate taxing agency. This will eliminate or substantially reduce travel expenses and typically gives us more time to properly prepare as this process takes time and the request to move an issue between offices is often granted. Moreover, if the issue has criminal implications, quite often the government’s suspicions can be advantageously “lost” in the shuffle.
Policy 2: Where it is not possible to employ the actions described above, we will discount our travel expense to approximate the travel time and expenses involved in interacting with one of our local taxing agencies.
Policy 3: David Klasing strategically co located each satellite office with a local IRS service center and a local airport to facilitate our office efficiently servicing remote client’s by Air. Mr. Klasing, in addition to being a perfect 10 AVVO rated Tax Attorney, with a Master Degree in Taxation and a stellar CPA, has his private pilot license, is instrument rated and owns a Cirrus SR22. He flies out of John Wayne Airport, collocated near the Irvine Main Office, to expedite travel in the Southern California area. For example a round trip drive to the Los Angeles office is often a 3.5 to 4 hour drive and the flight from John Wayne to Santa Monica Airport only takes 18 minutes. It is our policy never to charge our clients for the direct and indirect costs of Dave’s local air travel.
Policy 4: We compete based on providing above and beyond, effective and zealous representation for our clients, (see our testimonials and our A+ BBB rating) utilizing competitive billing rates which are often substantially lower than our competition, hiring only the most qualified, experienced and educated staff that are commercially available, passing work down to the lowest billing rates in our organization where possible for the type of work performed, striving to never take on a client who’s circumstances cannot be improved sufficiently to fully justify our fees. We will always place our client’s needs for affective, loyal and honest representation to obtain the optimal results in each individual client circumstance above the firms inherent need to make a profit.
