If you have an income, for instance, if you are self-employed, and you are not paid a salary from which taxes can be withheld, the government requires you to pay quarterly installments on your income tax. I hope this doesn’t come as unwelcome news to you! The “what if we refused” argument sure feels good, but do you really want them to come and take your house? They can, they have and they will.
Thank you for your concern, but I have already made legal arrangements should the worst happen.
To say any more would be to say too much to a stranger.
