Debt Recycling for Doctors and Dentists 

It is common to  see a dentist spouse with a large non-deductible debt, like a home loan which  is not tax-deductible.  This makes it very costly because if the interest on the loan is 6% and the doctors tax rate is 47%, the doctor has to earn  almost twice the amount to pay off the interest. This means the real cost of the interest on the loan is closer to 12%. That's why we always recommend that clients pay off non-deductible debt first. 

To avoid this situation,  a smart strategy would be  for the practitioner to use their practice’s cash flow to tackle this debt more efficiently. By carefully managing the practice’s finances, it’s possible to pay off that expensive non-deductible debt faster and save thousand of dollars.  

While the idea of obtaining a tax deduction is appealing it cannot be the main reason you are doing it. There must be a commercial purpose behind the strategy, namely asset protection. This means increasing the debt against the practice so that if the practitioner is sued, the equity available to a potential litigant is minimised. 

A Case Example

Recently, I had a dentist (let’s call him Bill) come in to see me with his wife. They had a well-established practice, lived in a beautiful big house held in the wife’s name for asset protection reaons. The problem however is that they had a one-million-dollar (non-deductible) mortgage that was eating up all their cash- flow!

By way of background, Bill is a sole trader dentist, with a Service Trust to which he pays a 60% of his professional fees based on his professional billings.

I see a lot of professionals in this situation, where they spend their lives paying back a loan to the bank, only to see their money going down the drain, in interest repayments.

Bill and his wife looked at me with despair, in the hope that I would come up with a practical solution to their problem.

So, I asked them this  question. If I could show you how  to arrange your practice banking so that we can achieve asset protection by building up the debt against your  practice and  at the same time paying off your home loan and recycling  it into  tax deductible debt, would you be interested? The answer was a resounding yes!  So I went on to explain how this could work.

The 2 Account System

As way of background, Bill is a sole trader dentist, with a Service Trust to which he pays a 60% of his professional fees based on his professional billings plus service fee plus lab fees. 

Step 1:  Bill will bank all of his practice income into his existing sole trader bank account. We will call this   bank account #1

Step 2:  Bill will set up a line of credit in his name as a sole trader, This will be used to pay all his business expenses. e.g. service fees, and all other business expenses  including tax and super tha he currently pays from his sole trader account. We will call this  bank account #2. This loan should be entirely separate from all other loans, although it can be secured against residential property if there is sufficient equity in a property to allow this.

Step 3: At the end of each month the funds in bank account #1( less any personal living expenses) will be transferred directly into the housing loan, until the home mortgage is paid off!

Step 4: Meanwhile bank account #2 (the line of credit), will be used for all the business expenses. e.g.Tax payments, Service Fess and Superannuation.
Step 5: At the end of every financial year June 30th,  Bill will calculate the interest that has accrued on the line of credit and transfer this amount from account #1 to account #2. This is important because the interest cannot be allowed to capitalise.

Step 6: Once the home mortgage has been paid put in full, Bill will go to the bank and ask them to refinance the line of credit, with a principal and interest loan in his sole trader account. 

Step 7: Now that bill has recycled all debt on the home loan, to a business loan, he will go back to using bank account #1for all  business income and expenses.

Here's what it looks like:


If you have a medical practitioner running his practice (without a Service Trust) , it would be done like this:

How Much Tax Can You Save?

If you have a tax deductible loan for $1,000,000 and pay interest of 6% p.a. which is $60,000 p.a. If your tax rate is 47% you would save tax of $28,200  p.a. each and EVERY year.  And claiming the interest on your mortgage will not trigger capital gains tax when you sell your home. This is because the interest you are claiming is on the business overdraft and not on your home!
