Corporation Tax
The Self-Assessment system 'Pay & File' applies to companies. The obligations of a company with regard to paying Corporation Tax and filing its return are as follows:

• Compute and pay its preliminary tax liability by the specified date (see below).
• File its return of income (including audited accounts where applicable) within nine months of the end of the accounting period. If this date is after the 21st of the ninth month the filing date is brought forward to 21st of the ninth month or 23rd in the case of returns filed electronically (21/23 day rule).
• Pay any balance of tax due when lodging the return i.e. within nine months of the end of the accounting period, subject to the 21/23 day rule.

Preliminary Corporation Tax
The total amount of preliminary tax paid must be equal to or greater than 90% of the company's final liability for the accounting period.

Income Tax
The Pay and File system provides the facility for you, on a single due date – 31 October, to:

• File your tax return for the previous tax year for Income Tax and Capital Gains Tax,
• Pay your Preliminary Tax for the current tax year,
• Pay any balance of Income Tax due for the previous tax year.

The single due date, 31 October, will allow you to pay and file at the one time. This date is referred to as the specified return date.

An important point to note is that if you wait until the Pay and File deadline of 31 October to file your return you will need to calculate your own tax liability.

Capital Gains Tax (CGT)
For 2009 and subsequent years the tax year is divided into a revised set of two periods for CGT payment purposes, as follows:

• 'initial period' - 1 January to 30 November, both inclusive.
• 'later period' - 1 December - 31 December, both inclusive.

The due dates for payment of CGT are now as follows:

• Disposals in the initial period: Tax due by 15 December in the same tax year.
• Disposals in the later period: Tax due by 31 January in the following tax year.

Capital Acquisitions Tax (CAT)
The Finance Act 2011 brought forward the Pay and File date for CAT from 31 October to 30 September. Therefore all gifts and inheritances with a valuation date in the 12 month period ending on the previous 31 August will be included in the return to be filed by 30 September. That means where the valuation date arises between 1 January and 31 August, the Pay & File deadline would be 30 September in that year; and where the valuation date arises between 1 September and 31 December, the Pay & File deadline would be 30 September in the following year.

Examples:

• Valuation date 21 February 2011: File IT 38 and pay tax by 30 September 2011.
• Valuation date 6 November 2011: File IT 38 and pay tax by 30 September 2012.

Value Added Tax (VAT)
VAT returns are normally prepared on a bi-monthly basis (e.g. January/February would be returned together). The VAT on sales for the two months as well as the VAT on purchases for the two months must be entered on the return and the difference paid over to the Revenue Commissioners. The deadline for submission of the return is the 19th day of the month following the VAT period (e.g. 19th March for the January/February return). If the return is filed and paid online (ROS) then the deadline date is extended to the 23rd of the month.

PAYE/PRSI & USC
Monthly P30s should be filed on the 14th day of the month following the period. This can be extended to the 23rd day of the month if you file online using the ROS system.

The yearly P35 should be filed on the 15th Februaryof the year following the return period.
