Tax filers sometimes are ready to "ignite like a matchbox" over a tax bill. As we get closer to the April 15th deadline this year, it's important to stay leveled. Letting the "fire" spread over to the tax office is not the solution.
There are many options available for resolving your tax debts. In fact, there are licensed individuals and companies that specialize in just that. There are many options available to pay as well. Gone are the days of only being able to pay with a check. We can't even say the same for paying rent. At least, not at the most conventional places.
If you are still unconvinced, you are more than welcome to have a reasonable debate. Just keep in mind that a years' worth of unpaid bills impairs your tax accountant's independence. It is not that they are avoiding your calls. If you managed to work with someone to the point where you are both ready to sign, keep a cool head.
After all, your tax bill is not a terminal medical diagnosis. You are only reviewing and signing your own tax return digitally in the comfort of your own home or are snacking on cookies at a reliable professional's office. You are not in the waiting room as someone in your family is going for a chemotherapy treatment. Stay in the present.
