Of course you would. The "HST Map" to getting to "Right" is exactly what you want. What should you do to get the right result every time? What should you do to collect the right amount of HST every time you make a supply? What should you do to calculate the right amount of input tax credits and recaptured input tax credits every time you file a GST/HST return? What should you do to recover the maximum amount of credits, refunds & rebates allowed? What should you do so that the Canada Revenue Agency says you are in the "Right" place when they complete any audit?
Unfortunately, these maps do not exist on supermarket shelves - but they can be generated or customized on a business-by-business basis by commodity tax lawyers and accountants. Where "Right" is for you depends upon the facts and where you want to go. Just as there are many cities and towns with the same name, there are many different "Right" destinations on an HST map. If you do not know where is "Right", how are you going to determine the path to take to get there? How can you be sure you are taking the correct route to "Right"? If you follow the directions someone else uses to get to "Right" you may be at the wrong "Right".
Once you can identify the destination of "Right", then a customized map can show you how to get there. The customized map will set out the process that you must follow to get to your chosen "Right" destination. The directions are a critical part of the map to "Right".
The HST map may take the form of a memorandum or opinion letter. Sometimes the process involves seeking additional directions, which would be in the form of an advance GST/HST ruling from the Canada Revenue Agency.
It is possible to hire a commodity tax lawyer or accountant to prepare a customized HST map if you would like to get to "Right" and stay there. These maps do exist - believe it or not. Would you like one?
I should add one closing note that the Department of Finance may move "Right" on you when you are not looking. Just like with the television show "Lost", you may find that you are no longer where you thought you were/should be. Maybe the producers were thinking about the tax authorities when they came up with the plot for "Lost" --- hmmmm
