Corporation tax
be careful not to confuse the calendar year and your fiscal year for your company. Preliminary tax payment obligations are explained here. This is only for corporation tax

**New or Start-up companies
New or Start-up companies with a Corporation Tax liability of €200,000 or less for their first accounting period will not be required to pay Preliminary Tax in respect of that first accounting period and will instead be required to pay their final Corporation Tax liability for that accounting period at the same time as they are required to submit their Corporation Tax return, i.e. within nine months after the end of the accounting period,
PAYE/PRSI
Is the 40k paye/prsi/usc - the link in my previous post should cover that -
Edit -- going by this it is due by the 15th of Feb with your P35 for 2011 [broken link removed]
--any later then that and the following applies
Where insufficient amounts are paid by direct debit and there is a balance of tax payable at the end of the accounting year, interest is payable if the amount is not paid by the due date. In addition if the amount due exceeds: 10% of the annual liability for PAYE/PRSI,
interest will be back-dated to the mid point of the accounting year. i'm guessing here they mean the calendar year......
(currently at the rate of 0.0322%) for each day or part of a day for which payment is overdue.
