Register for VAT in Ireland

The Irish VAT thresholds, and how the rolling twelve months works

Registration becomes obligatory once your turnover from taxable supplies exceeds the relevant threshold in any twelve-month period. Revenue's principal figures are €85,000 for the supply of goods and €42,500 for the supply of services. A business supplying both goods and services uses the €85,000 threshold where 90% or more of turnover comes from goods; otherwise the lower services threshold applies. The €42,500 threshold also catches businesses that manufacture or produce goods liable at the reduced or standard rate from zero-rated materials.

The critical detail is the word rolling. The test is not your calendar-year figure and not your accounting-year figure — it is any twelve consecutive months. A consultant who bills €3,800 a month crosses €42,500 in month twelve regardless of when the financial year ends. Equally important, the obligation is forward-looking: where it is reasonably foreseeable that you will exceed the threshold in the next twelve months, Revenue expects you to register before you cross it, not after.

Two separate thresholds catch businesses that would otherwise be well under the main limits. Acquisitions of goods from other EU Member States trigger registration at €41,000 in a twelve-month period. Intra-Community distance sales of goods and cross-border telecommunications, broadcasting and electronic services into the State are caught at €10,000, measured across all EU Member States rather than Ireland alone. Businesses not established in the State generally have no threshold at all and must register from their first taxable supply here.

• €85,000 — supply of goods
• €42,500 — supply of services
• €41,000 — acquisitions from other EU Member States
• €10,000 — intra-EU distance sales and cross-border TBE services
• No threshold — most businesses not established in the State

Electing to register when you are under the threshold

Traders below the thresholds are not obliged to register but may elect to. Whether that helps depends almost entirely on who your customers are. If you sell to VAT-registered businesses, they reclaim whatever VAT you charge, so registering costs them nothing and lets you recover VAT on your own equipment, software, professional fees, and stock. If you sell to consumers, adding 23% to your prices either makes you more expensive than an unregistered competitor or eats your margin.

The second common reason to elect is start-up recovery. A business that has set up but not yet made taxable supplies can reclaim VAT on start-up costs only if it is registered. For a trade with heavy pre-trading spend — fit-out, plant, vehicles, professional fees — that recovery can be worth more than the compliance cost of returns.

Election is not free. Once registered you file returns whether or not you traded, you must issue compliant VAT invoices, and deregistering later can trigger a clawback of VAT reclaimed on assets you still hold. Treat it as a decision to model rather than a default, and revisit it if your customer mix shifts from business to consumer.

How to get a VAT number: TR1, TR2, and ROS

Businesses established in the State register through the Revenue Online Service. Individuals, sole traders, trusts, and partnerships complete Form TR1; limited companies complete Form TR2. Both forms handle more than VAT — the same application registers you for income tax or corporation tax and for employer PAYE where relevant, so it is worth completing the whole picture in one pass rather than returning to add taxheads later.

Applicants whose business is not established in the State cannot use the online route and must submit the paper equivalents, Form TR1 (FT) or Form TR2 (FT). Non-established traders are also the group most likely to be asked for supporting documentation, because Revenue is assessing whether there is a genuine taxable activity in the State.

Expect to evidence your trade. Revenue's registration guidelines allow it to seek proof that you are carrying on, or about to carry on, a taxable business — contracts, purchase orders, supplier invoices, a lease, a website, or bank activity all help. Applications supported by real trading evidence clear faster than applications that assert an intention with nothing behind it. Registration normally takes effect from the date stated on the form, and where you are electing to register the effective date will not be earlier than the start of the taxable period in which you apply. Backdating beyond that is possible only by agreement with your Revenue office.

• TR1 — resident individuals, sole traders, trusts, partnerships (online via ROS)
• TR2 — resident limited companies (online via ROS)
• TR1 (FT) / TR2 (FT) — non-established applicants (paper)
• Supporting evidence of taxable activity speeds approval

Domestic-only versus intra-EU registration

Irish VAT registration is two-tier. A domestic-only registration covers supplies and acquisitions within the State. An intra-EU registration additionally allows you to trade cross-border within the European Union and to appear as a valid trader on the VIES system that your EU customers will check before zero-rating a supply to you.

Choose deliberately at application stage. If you buy services from EU suppliers — cloud software, advertising platforms, contractors based in other Member States — you are likely to need intra-EU status to account for those purchases correctly under the reverse charge. Applying for intra-EU status invites closer scrutiny, so have your trading evidence ready.

Getting this wrong is a common and expensive mistake for small digital businesses. A domestic-only registration means EU suppliers charge you their local VAT, which you generally cannot reclaim through an Irish return, converting a recoverable cost into a dead one.

What changes the day your registration takes effect

From the effective date you charge VAT at the correct rate on taxable supplies — 23% standard, 13.5% and 9% reduced rates for specified goods and services — and you must issue invoices carrying your VAT number, the rate applied, and the VAT amount. Revenue issues a VAT registration certificate confirming that number; keep it with your records and use the number on every taxable invoice. Getting invoice format right matters because your business customers need a compliant invoice to reclaim.

Returns follow after registration, not instead of it. Most newly registered businesses file a VAT3 return bi-monthly through ROS, though Revenue may assign less frequent periods to smaller traders. Separately, an annual Return of Trading Details reconciles your supplies and purchases by rate across the year. For VAT 3 drafts and ROS packs, use VAT return services Ireland — this page stops at getting registered.

Underneath all of it sits record keeping. You need purchase and sales records that support every figure, receipts that evidence the VAT you reclaim, and a clean separation between business and personal spending. This is where most first-time registrations come apart: the obligation is not the return itself but the twelve months of evidence behind it.

How FinnAccountings prepares you to register

FinnAccountings monitors your rolling twelve-month turnover from connected bank feeds and invoices, so you see the €85,000 or €42,500 threshold approaching months before you cross it rather than discovering it in a year-end review. That lead time is what lets you register at the right moment and price your contracts accordingly.

Once you are registered, transactions are categorised and matched to receipts as they arrive and VAT is separated by rate — the records you need on day one of registration. Draft VAT 3 figures and ROS packs live on VAT return services Ireland; this page is the registration and VAT-number guide.

You or your qualified adviser submit the registration to Revenue through ROS. FinnAccountings is bookkeeping and VAT preparation software, not a registered filing agent, and AI carries no legal accountability for what is submitted in your name — which is precisely why the review step matters.
