  • Keep your tax affairs compliant to avoid refusal (Revenue eTC system page)

The pattern is clear: the process is standardised but depends entirely on your compliance history.

How to get a tax clearance certificate in Ireland?

Applying online through Revenue’s myAccount or ROS

  • Log in to Revenue Online Service (ROS) or myAccount.
  • Select ‘Tax Clearance’ from the main menu.
  • Complete the electronic application; Revenue checks your tax compliance automatically (Revenue eTC system page).
The upshot

You don’t upload documents — Revenue checks your records behind the scenes. If everything is clean, the certificate is issued the same day in most cases.

Step-by-step application for individuals

  1. Register for myAccount using your PPS number.
  2. File any outstanding returns and pay any due taxes.
  3. Go to ‘Manage Tax Clearance’ and submit the application (Revenue eTC system page).

The pattern: submission triggers an automatic compliance check.

Step-by-step application for companies and connected parties

  • Companies apply via ROS using their company registration number.
  • Revenue also assesses connected parties — directors, major shareholders — and they must have their own clearance (Revenue tax clearance main page).

Documents and information needed

  • PPS number (individual) or company registration number.
  • Revenue registration for Income Tax, VAT, or PAYE as applicable.
  • No physical documents — the system uses your filed returns and payment history.

The implication: if your returns are up to date and you owe nothing, the certificate is almost instant. If not, you’ll get a refusal with reasons.

Can I check a tax clearance certificate online?

Using the eTax Clearance (eTC) system

Revenue’s eTC system lets anyone verify a certificate. You enter the holder’s Tax Reference Number and the Tax Clearance Access Number (TCAN) they provide (Revenue eTC system page).

Checking a contractor’s or supplier’s certificate

  • Ask the contractor for their TCAN and their PPSN or Tax Reference Number.
  • Visit the eTC verification page on Revenue’s site (Revenue eTC verification page).
  • The system returns a simple valid/invalid status.

What information is shown in an online check

  • Certificate validity (valid or expired).
  • Date of issue and expiry.
  • No financial details are revealed.
Why this matters

Third-party verification protects both parties — a contractor knows you’re genuine, and you know they’re compliant. It’s free and takes 30 seconds.

The trade-off: you must have the TCAN to check. Without it, no verification is possible.

Why do I need a tax clearance?

Mandatory for public sector contracts and grants

Any public contract valued at €10,000 or more requires a valid tax clearance certificate (Citizens Information state agency). State grants, including those from enterprise boards, also demand it.

Required for certain licences and permits

  • Liquor licences, gaming licences, and certain taxi licences.
  • Some professional certifications and government tenders.

Benefits of holding a valid tax clearance certificate

  • Proof that your tax affairs are up to date.
  • Improves credibility with suppliers and customers.
  • Speeds up applications for grants and licences.

In short, it’s a trust badge that reduces friction when doing business with the State or large organisations.

How long does it take to get a tax clearance cert in Ireland?

Standard processing times

Most applications are processed within 5 working days (Revenue tax clearance main page). If your tax affairs are fully compliant, the certificate is often issued immediately upon submission.

Factors that can delay the application

  • Unfiled tax returns.
  • Outstanding tax liabilities.
  • Connected parties (directors, partners) who are not compliant.

Expedited or urgent requests

Revenue does not offer a formal expedited service. The fastest path is to ensure all returns are filed and payments made before you apply.

The pattern: the smoother your compliance history, the faster the turnaround. Delays signal a problem somewhere in the system.

Where to find Tax Clearance Certificate on ROS?

Navigating the ROS menu for tax clearance

  1. Log in to ROS at ros.ie.
  2. Click ‘Tax Clearance’ from the main services menu.
  3. Select ‘Manage Tax Clearance’ to view your current status (Revenue tax clearance main page).

Downloading or printing your certificate

  • From ‘Manage Tax Clearance’, choose the active certificate.
  • Select ‘View/Print’ to download a PDF copy.

Accessing eTC for third-party verification

  • Your certificate includes a TCAN (Tax Clearance Access Number).
  • Share this number with the third party along with your PPSN or Tax Reference Number so they can verify online (Revenue eTC system page).

The catch: you must have your TCAN handy — without it, the recipient cannot verify your certificate.

Upsides

  • Free to apply and renew
  • Online system is fast when compliant
  • Verifiable by third parties in seconds
  • Valid for 18 months

Downsides

  • Must be fully tax compliant — no room for outstanding returns
  • Non-residents face additional registration steps
  • No expedited option if urgent
  • Expires after 18 months; renewal is required

Confirmed facts

  • Tax clearance certificate is issued by Revenue.
  • It is required for public contracts over €10,000.
  • Application is free and done online.
  • Certificate is valid for 18 months.

What’s unclear

  • Exact processing time for complex cases with multiple connected parties.
  • Whether a non-resident without a PPS number can apply directly (must register first).
  • What happens if application is delayed beyond 5 working days – Revenue does not guarantee specific timeline.

What the experts say

For businesses and sole traders in Ireland, the choice is simple: keep your tax affairs clean, apply online, and you’ll have a certificate that unlocks public contracts, grants, and credibility. For non-residents, the path requires an extra registration step — but the same compliant posture applies. Fail to file or pay, and the system blocks you.

Frequently asked questions

What is a tax clearance certificate?

It’s a confirmation from Revenue that your tax affairs are in order — no outstanding returns or unpaid taxes.

What documents are required for a tax clearance application?

You need your PPS number (individual) or company registration number, and your Revenue registrations must be up to date. No physical documents are uploaded — Revenue checks its own records.

Can I get a tax clearance certificate if I have outstanding taxes?

No. Revenue will refuse the application until all outstanding returns are filed and taxes are paid (Revenue eTC system page).

How do I renew my tax clearance certificate?

Log in to ROS or myAccount, go to ‘Manage Tax Clearance’, and submit a new application. The process is the same as the initial application.

Do I need a tax clearance certificate as a sole trader?

You need one if you want to bid for public contracts over €10,000 or apply for State grants. It’s not required for everyday private work.

How does a non-resident apply for a tax clearance certificate?

If registered for Irish tax, apply online via the eTC system. If not registered, complete Form TC1 and email it to nonrestaxclearance@revenue.ie (Revenue non-resident page).

Is a tax clearance certificate the same as a VAT clearance?

No. A tax clearance certificate covers income tax, corporation tax, VAT, and PAYE. It’s broader than just VAT.

What should I do if my tax clearance application is refused?

Revenue will provide the reason. Address the issue (file returns, pay taxes, resolve connected party gaps) and reapply.
