Every year I pay enough estimated taxes to be owed a refund or rollover. Every year, Turbo Tax is applying a small fine for not paying my estimated taxes correctly. There is never any explanation. Why does TTax apply this penalty when the total estimated tax payments are always well over the amount owed? I make quarterly payments that are all reasonably at least a quarter share of anticipated tax liability for that tax year (minus the rolled over amount). How do I avoid this penalty?
