Form 11, LPT, CGT and pensions: EOFY accounting deadlines are here.
Get into your finances in early October to avoid losing out on deductions.
The last quarter of the year is the busiest time of year for accountants, the self-employed, and most businesses. Avoid a last minute panic and the financial costs of late compliance. And, if in doubt, get professional advice earlier rather than later!
Income Tax 2024 – Form 11
It’s time to submit self-assessment tax returns for the year 2024 (Form 11). Late filing may mean penalty surcharge, added interest, and public listing by Revenue. Get your income tax information now and get it to your accountant as quickly as possible.
- The ROS Pay and File deadline for Income Tax Returns (Form 11) is 19th Nov 2025.
- Paper applications must be lodged by October 31st.
- You may also be required to pay preliminary tax. Ensure you have sufficient funds for this, or contact your accountant to make arrangements with Revenue as a priority.
Form 11 – what information to collect
As well as income from all sources, other useful information includes:
- details of capital gains and losses;
- medical expenses;
- details of rental expenses if claiming the rent tax credit;
- remote working expenses if claiming remote working tax relief;
- details of mortgage interest on principal private residence if claiming the mortgage interest tax credit;
- and details of any pension contributions.
Ensure you claim all allowable business expenses
Reduce your tax liability by ensuring you have the correct documentation and applied for any deductions available while running your business. Talk to your accountant now – if you leave it too late, you will probably miss out. Common allowable expenses can include:
- Rent and rates
- Energy
- Car, van and travel
- Repair and maintenance of plant and equipment
- Insurance costs
- Consultancy fees
- Advertising
- Business loans and interest on loans
- Asset purchase
It is essential all your details are up to date and accurate; if in doubt, get advice earlier rather than later.
Other financial deadlines include:
Gifting and Capital Gains Tax
You can make a tax-free gift of €3,000 per person each year. This annual gifting exemption closes on 31 December.
Where Capital Gains Tax (CGT) applies, the dates you pay and file CGT are based on the date you sold, gifted or transferred an asset. Ensure you have explored all your options and availed of any applicable reliefs well in advance of these dates.
When you have gains or dispose of an asset, you must:
- Pay CGT by 15 December of the same year (if the disposal is in December, the deadline is 31 January).
- File a tax return for CGT by 31 October of the following year.
Pension planning
Company owners and employees alike should check in on their pension options and obligations well before the year end deadline of 31st Dec 2025.
You can reduce your personal tax by making contributions to your pension scheme. You may pay a once-off, or special, contribution after the end of a tax year but time is limited: if using ROS, you have until the Pay and File deadline of 19th November 2025 for the tax year 2024.
Local property tax
The next valuation period for Local Property Tax is approaching. All property owners must complete three key steps:
- Determine the valuation band of their property as at 1 November 2025.
- Submit their LPT Return, including the valuation band, by 7 November 2025.
- Pay, or make arrangements to pay, the LPT charge for 2026.
This new valuation band will apply for all LPT charges due from 2026 to 2030.
For more information, see Revenue’s Local Property Tax (LPT) liability page.
Check in with your accountant now to maximise any savings and minimise stress.
- Avoid penalties and interest on late payments.
- For companies, missing the Annual Return deadline with the CRO results in the automatic loss of audit exemption for the current year and the following two financial years.
- Early preparation gives your accountant time to identify and claim all eligible deductions, capital allowances and tax credits, ensuring you don’t overpay tax.
