10% to 20% “New Client” Referral Fee

Since virtually all of our growth comes from client referrals, we offer a generous referral program for new tax clients as a way of saying “thank you”.

You receive a 10% referral fee for any Partnership, Corporation, S Corporation, and Trust new client referral. For individual returns we offer a 20% referral fee for every new client you refer. The fee will be paid after the tax return is completed and filed by this firm and after full payment by the client. The more you refer, the more you make. For example, for every new client you refer you may make anywhere from 10% to 20% of the fees we charge for this new client. The referral percentage depends on the type of work completed.

The referral fee provided in this program will be included in the signed client engagement agreement prior to any work performed. This Referral Program is allowed under the American Institute of CPA “Code of Professional Conduct” section 1.520.001. This AICPA rule is accepted by state Board of Accountancy organizations in 48 states excluding California and Hawaii. Therefore no referral fees may be paid for any new clients located in these two states.

We’re sure these new clients will thank you for that referral after they see the excellent work we provide!

“James identified a difficult and complex tax issue that required resolution. This particular issue was unusual and potentially quite troublesome. James supervised analysis and resolution of this issue in a very professional manner. His handling of the issue demonstrated a very good grasp of highly complex legal issues balanced by sound and mature judgment.”

“I contacted James Duffy at Tax Client Services to have him prepare the financial statements and tax returns for Aapex Financial Solutions, LLC. He did a great job preparing my friend’s tax return, significantly reducing their tax liability. They were impressed on how detailed he was as he looked at all of the tax planning techniques allowed under the tax law. My friends liked that he looks at your prior year tax returns to determine if there are any missed tax deductions without any up-front charge. He then found a lot of tax savings! With that background I had no issues asking for his assistance on this project. He helped me on issues with the California Residential Mortgage division, the US department of HUD, reviewed my prior year financial statements and tax returns, etc. He identified important issues in the prior and current year tax returns. It is a given that I will continue with his services. He is a very accomplished professional and a pleasure to work with. I highly recommend Tax Client Services!”

James was very easy to work with and took the time to explain complex tax regulations in a way that was easy to understand. I would highly recommend James.”

I have great respect for James and his firm Tax Client Services. He is personable, trustworthy and frankly brilliant in his field. His tax and accounting experience, knowledge and ethical character are of the highest standards. He has the ability to focus on key tax issues that make a difference that is rarely seen these days.

His many strengths include how determined and focused he is in taking care of his clients tax and accounting problems. James is a polished and experienced tax professional, one whom you can count on to go the extra mile and who will do everything possible to ensure his clients pay the absolute minimal amount of taxes possible.

“James was hired because of his outstanding tax expertise. He worked on tax issues related to financial statement documents backing the bank’s submission of its 10-K, 10-Q and other SEC submissions. He was responsible for tax compliance and filings for a $6 Billion market cap company. His knowledge of the tax law led to substantial savings for the bank. One example was the bank’s foreign earnings repatriation strategy–$8 million in federal taxes were saved as well as some $2 million in state taxes. James is a master at sorting through details on tax issues and used this to reach correct tax applications to the benefit of the bank.”

“I’ve known James Duffy for over thirty years and rely on him for rock solid tax and accounting advice and the very latest in clever AND LEGITIMATE solutions to complex situations. I am very comfortable referring him to my associates and friends and know they will receive the same high standard of care he delivers to his national clients, and to me. He never fails to go the extra mile and has always been a proactive part of every situation I have dragged him into. While many consultants see clients as mere engagements his style is much more comprehensive and it’s not unusual at all to get an email from him at an odd hour treating the topic we’ve been kicking around. I am confident that he is the best of the best.”

“James has been helping me with my taxes since 2010 and I am happy about how effective his solutions are and most important – I am very happy with the money he saves for me. His ability to focus on taxes like nobody I have ever seen is actually amazing. He asks a lot of questions always looking for ways to lower my taxes. Don’t be surprised to get detailed emails discussing your issues without any charge on his part at odd hours of the day or night. He cares about his work and I have been always amazed at how he comes up with tax ideas that really work and are legal which is a very important thing for me. He is friendly and fast thinking and returns your phone call promptly, is easy to reach, and will make sure you pay the least amount of taxes possible. He is a God sent tax geek and I would highly recommend James to anyone of my friends.”
