Sonatta, our property taxes are due twice a year in May and November.  Oops-misread the question, thanks Susan!!!!  We pay quarterly estimated taxes and we usually write a check as we still owe and write another check by April 15th.

My opinion is you should pay estimated taxes each quarter. If you pay all the taxes sometimes in say March or April of the following year you will be assessed interest penalty and the rate is not a good one.. If you pay quarterly and even if you owe more than you paid the interest impact will be much smaller and you will save money. 

Our taxes are paid quarterly and anything else still owed is paid at time of filing. It's scary hearing some agents at this time of the year saying they haven't paid anything throughout the year and don't have what they owe.

Are you talking about quarterly estimates for income tax?  Definitely quarterly. ;-)  

Seems like I am always paying taxes.

Quarterly.

At once.

Quarterly.

If you don't make quarterly payments, you'll be assessed a penalty. It's better to make the quarterly payments and save yourself some money.

with a mortgage it is handled by the escrow account. If you have no mortgage it is twice a year in SC County, CA

We pay our taxes quarterly so that we're not hit with a huge bill all at once!

I pay quarterly estimated taxes. I usually put about 1/3 of each commission check in a savings account so that when the end of the quarter arrives, I have the money set aside and ready to go. 

I pay quarterly for estimated IRS and state taxes, semi-annually for property taxes.

Good timing for this question. I usually do once/year and often need an extension( when I'm out of the country). I do use the professional service for filing. 

I pay income taxes quarterly. 

We pay quarterly then pay the taxman a lump sum in April.
