Estimated taxes

[Milburn Stone]

I got a federal tax refund last year.  This year, due to the midyear sale of a vacation property and a late year Roth IRA conversion, I will owe taxes.  But because last year's tax liability was less than zero, do I need to make estimated tax payments this year?

Thank you.  I suppose that the rules are straightforward enough.  As long as I have made estimated payments equal to the lesser of at least 90% of the tax owed for the current year (I have not), or 100% of the tax shown on the return for the prior year (which I suppose I have, because last year I got a refund), then I am in compliance.  I am simply uncomfortable with making no estimated tax payments this year simply because I got a refund last year, when this year's tax liability will be quite high because of two non-recurring events.
