What Is The Cash Dam and How Does It Work?
The Cash Dam (sometimes referred to as a “cash flow dam”) is a simple but powerful concept, and it’s an especially attractive option for those who are familiar with the Smith Manoeuvre or other tax minimization strategies. Cash Dam can help you with tax optimization if you have a mortgage and own either a small business or a rental property.
What is cash damming?
The Cash Dam allows the owner of a small business or rental property to more quickly pay down their non-deductible mortgage on their home. It’s a variation on the Smith Manoeuvre, but without additional investing. The Cash Dam is essentially an expedient way to change bad debt into good debt.
For someone who’s using the Cash Dam, what it involves is using a line of credit to pay for business expenses. Then, while using the increased business cash flow, you pay down a non-deductible mortgage or loan. This, in turn, produces an increasing tax-deductible business loan, while paying down a non-deductible mortgage or loan. Be advised that the Cash Dam as described above will only work for those who own a non-incorporated personal or partnership-based small business or a rental property.
If you own a small non-incorporated business that has $2,000 in expenses each month and you also have a readvanceable mortgage, then the $2,000 per month expense would be paid by the home equity line of credit (HELOC). You then use the additional $2,000 you have in your business expense account to make a payment on your non-deductible mortgage. Interest paid on money that’s borrowed for business expenses is tax-deductible; by using the Cash Dam, you’ll be left with a tax-deductible business loan and a non-deductible mortgage that’s been quickly paid down.
One of the keys to the Cash Dam, however, is capitalizing the interest on the business line of credit. That way, you avoid using any of your own cash flow and you keep the business line of credit tax-deductible.
How does the Cash Dam differ from the Smith Manoeuvre?
The Cash Dam relies on using a tax-deductible business loan to allow you to pay down a non-deductible debt, while the Smith Manoeuvre allows you to buy investments. Investing from your credit line is why the Smith Manoeuvre has much higher risk and return than the Cash Dam.
Say that you’re a rental investor, instead of using your own cash flow to pay for rental-related expenses, you can use the Cash Dam and a line of credit. In this instance, using the Cash Dam would help you pay for your personal mortgage and help you satisfy your tax obligations as well.
And if you are a small business owner, the Cash Dam can be extremely advantageous. The strategy gives you a way to quickly pay down your non-deductible mortgage and convert that debt into a tax-deductible business loan.
