Pay & File 2026: What Self-Employed People and Landlords Need to Do Now
With summer winding down and the calendar turning to autumn, one date every self-employed person and landlord in Ireland needs to have firmly in their diary is 18th November 2026. That is the extended Pay & File deadline for your 2025 income tax return (Form 11) and missing it can cost you significantly in surcharges and interest.
Whether you are a sole trader, a landlord, a company director, or a freelancer, this guide walks you through everything you need to know about the 2026 Pay & File deadline, what you need to gather, and how to make the process as painless as possible.
What is the Pay & File deadline?
The Pay & File system is how self-assessed taxpayers in Ireland submit their annual income tax return and pay any outstanding tax. There are two key dates for 2026:
-
31 October 2026: the paper filing deadline for your 2025 Form 11 and preliminary tax payment
-
18 November 2026: the extended deadline if you both file and pay through Revenue Online Service (ROS)
The ROS extended deadline is the one most people work towards, and it applies only when both the return AND the payment are completed online via ROS. If you file online but pay by cheque, for example, the earlier 31 October deadline applies.
Who needs to file a Form 11?
You are required to file a Form 11 if any of the following apply to you:
-
You are self-employed or a sole trader
-
You earn rental income as a landlord
-
You are a company director (with or without a salary)
-
You have non-PAYE income over €5,000 in the 2025 tax year
-
You received income from dividends, investments, or foreign sources
-
You were newly self-employed at any point during 2025
If you are unsure whether you need to file, it is always worth checking with an accountant. Failing to file when required can lead to penalties just as filing late can. You can find further guidance on Citizens Information.
What is Preliminary Tax and why does it matter?
Preliminary tax is an advance payment of your expected 2026 income tax liability, and it must also be paid by the Pay & File deadline. It is one of the parts of the system that catches people off guard.
To avoid any interest charge from Revenue, your preliminary tax payment must be either:
-
90% of your final 2026 tax liability
-
100% of your 2025 tax liability (the safer option if your income is similar year to year)
Getting this right matters. If you underpay preliminary tax, Revenue charges daily interest at 0.0219% per day, which adds up quickly if left unaddressed. A good accountant will help you calculate the right amount so you are not overpaying or leaving yourself exposed to interest charges.
What happens if you miss the deadline?
Missing the 18th November 2026 deadline is not the end of the world, but it does come with financial consequences:
-
5% surcharge on your tax liability if you file within two months of the deadline (capped at €12,695)
-
10% surcharge if you file more than two months late (capped at €63,485)
-
Daily interest on any unpaid tax from the original due date
These amounts can escalate quickly, particularly for anyone with a significant tax bill. Filing on time, even if you cannot pay everything immediately, is always the better approach, as Revenue is generally more flexible with payment arrangements than with surcharges.
What should you start gathering now?
The best way to take the stress out of the November deadline is to start pulling your records together now. Here is what you will typically need:
-
Income records: invoices, bank statements, sales figures for the year
-
Expense receipts: allowable business expenses reduce your taxable income
-
Rental income and costs: rent received, mortgage interest, management fees, maintenance costs
-
P60 or employment income details: if you also have PAYE income
-
Details of any capital gains or disposals during 2025
-
Previous year's tax return: useful for comparing and calculating preliminary tax
The earlier you gather this information, the earlier your accountant can work on your return, and the less likely you are to face a last-minute rush in November.
It is also helpful to keep personal and business transactions clearly separated, and to note the purpose of less obvious expenses while the details are fresh. Digital copies are fine, provided your records are complete and easy to follow. If you own a rental property with other people, gather the ownership percentages and confirm how the rental income was divided. Clear records make it easier to identify deductions, resolve questions quickly, and submit an accurate return with confidence.
Do not wait for every figure to be perfect before making a start. A first pass can identify missing statements, unfamiliar transactions, or questions about what is allowable. Your accountant can then help you fill the gaps and flag planning opportunities before the return is filed, rather than after the deadline has passed.
