What we do

Tax advice that starts with your numbers

A tax consultant earns their fee when the answer depends on your situation. Salary or dividends. Whether a purchase qualifies for capital allowances. Whether you are about to cross the VAT threshold.

We look at the whole picture first, personal and business together. Then we work out what Revenue expects and when, file what needs filing, and keep looking for what could be done better.

Limited companies

Preliminary CT (small companies): month 11CT1 and balance: 23rd of month 9 after year-endFiled on ROS with iXBRL accounts

These are the standard dates. Filing and paying on ROS extends several of them, and Revenue sometimes changes dates for a given year. We track yours so you do not have to.
Budget 2027

What changed on 6 October, in plain terms

Most changes take effect on 1 January 2027.

Income tax band

€46,500

The 20% band for a single person from 1 January 2027, up from €44,000. The 40% rate starts after it. A one-income couple moves to €55,500.

From 1 January 2027

The personal, employee and earned income credits each rise by €125. The home carer credit rises by €100 to €2,050.

From 1 January 2027

A PRSI increase that was already in law took effect for employees, employers and the self-employed on 1 October 2026.

Already in force
The 2% USC band now runs up to €30,300. Budget 2027 also enhanced the R&D tax credit and made administrative changes to preliminary corporation tax. Which of these touch you depends on your income and your company, which is what a call is for.
Do you need one?

When a tax consultant is worth calling

Call us if

  • You own a limited company and pay yourself from it
  • You have income from more than one source
  • You are close to a VAT threshold or selling abroad
  • Revenue has written to you or opened a query
  • You are buying, selling or gifting a business or shares

  • You are a sole trader with simple income and use bookkeeping software
  • You only need to check one routine filing
Choosing any adviser: ask which professional body they belong to, whether they carry professional indemnity insurance, and who will actually do your work.
Quick answers

Tax questions we hear most

Short, plain answers.

What is the difference between a tax consultant and an accountant?

They overlap. An accountant usually prepares accounts and returns. A tax consultant advises on decisions before they are made, such as structure, timing and reliefs. With us the same team does both, so the advice and the filing match.

What are the main tax deadlines this year?

For self-assessed taxpayers the 2025 Form 11 is due on 31 October 2026, extended to 18 November 2026 if you file and pay through ROS. Companies file their CT1 by the 23rd of the ninth month after year-end. VAT3 returns are due on the 19th, or the 23rd on ROS.

Do I need to file a return if I am on PAYE?

If PAYE is your only income, usually not. If you also have rental, self-employed or other untaxed income, you generally need to file. Revenue myAccount shows what Revenue already holds on you.

What happens if I file late?

A surcharge applies to a late return: 5% of the tax due, up to €12,695, if you are less than two months late, and 10%, up to €63,485, after that. Interest also runs daily on tax paid late.

How much corporation tax will my company pay?

12.5% on trading profits and 25% on non-trading income such as passive income. Large multinational groups with consolidated revenue of €750 million or more are in a 15% regime.

Can you deal with Revenue for me?

Yes. Once you link us as your agent on ROS we can file, pay and respond to Revenue queries on your behalf.

Does Budget 2027 change what I pay?

Most people will pay a little less income tax from January 2027, because the 20% band rises to €46,500 for a single person and the main credits rise to €2,125. The PRSI increase from 1 October 2026 takes back some of that. Your own figures depend on your income.

Ready to talk through your tax position?

Tell us who you are, what you earn from and what is worrying you. You will leave the call knowing what is due, when, and what to do next.

  • How you earn: PAYE, self-employed, company or rental
  • Your latest return or accounts, if you have them
  • Any letter or query from Revenue
  • What you are planning in the next 12 months
