Best to get proper advice to start with when setting up the structures - involves more than just the tax issues mentioned.
Corporate protection, income distribution, asset protection, as well etc.
Setting up the correct structure of companies, trusts, super etc at the beginning can remove a lot of doubt and jeopardy.
Term for the business is "Shelf Company Provider"
Years ago it'd take up to a month to get a company registered, so we'd register a heap and keep them on the "Shelf" to transfer over to clients when required.
eg - if you were going to buy a property on the weekend and needed it to be under a corporate structure you'd pick up one of our Shelf Companies Friday arvo and be ready to sign contracts.
These days I can get a company registered almost immediately so there's not as much call of pre-registered companies although I do keep a supply on hand for clients who need something backdated.
Most of the clients are accountants - for them to be doing it themselves it'd be taking them away from their core business (spending time doing stuff that isn't billable or part of their field), have to put on another staff member to focus on the area and require them to keep up to date with any changes or developments that is at a total tangent to their main work.
Some will order 1 every 8 months - not worth it for them to gear up to be able to do it themselves.
Others will order 10 a week - short of hiring an extra staff member and ensuring they are current on everything it's not worth them doing it themselves.
Also makes it easier for them to pass the costs onto the client if they have an invoice from us with a properly presented folder.
