Estimated taxes to be paid every quarter? Can it be done once a year?

[misterno123]

I know it has to be done every quarter but can I pay all of it just once and be done with it?

'

Or IRS imposes 4 payments as a rule?

The IRS would be happy to have all of it paid before the due dates. 

[misterno123]

so does that mean I can pay only 1 time and be done with it? Say December 30 ?

you must make quarterly payments on or before the due date(s), or risk penalties for not making a payment.

As I wrote, you have to pay before the payment is due so if you pay the total for the year in one payment, you would have to pay before April 15. If you have already paid the April amount you can pay for the remaining year now in one payment.
