Nope, and it usually makes sense to do under the current tax law - as long as they don't change the rules about refundable franking credits! Also look at whether your company will be changing from a base rate entity to a standard 30% tax rate entity. If it's been running a business and taxed at 25% until now, you may find post retirement you are able to frank at 30% if more than 20% of the company's income is from passive sources after retirement. That would likely leave you with an amount towards the end of your distributions that cannot be franked, but allows you to get more franking credits out now. Chat with your accountant about all this
