Problem paying income tax

Having had my books audited by my accountant; she has estimated that I currently have an outstanding income tax bill of just under 3k.

Problem is I have no way of paying the 3k in full. Will the revenue accept installments each month to clear this liability and what would be the appropriate repayment figure each month that they are likely to accept?

Would it be best to ask the accountant to ring them instead of myself?

Thanks in advance?

Outstanding income tax re 2010 or 2011?
If 2010, interest will be due. Your accountant is the best person to talk to Revenue and set up a payment plan.
Income tax for 2011 not due yet, so you have time to top up whatever preliminary tax you paid.
