When a sole-trader business moves into an Irish limited company, keeping the same shop, customers and brand can make it feel as though only the name has changed. For VAT administration, that assumption can create problems. The individual and the incorporated company need their own positions reviewed.
This guide answers the narrow handover question: what happens to the VAT identity and invoicing when an existing sole trader starts operating through an LTD? It complements our broader incorporation guide rather than replacing advice on transferring assets, contracts or employees. Revenue sources were checked on 18 October 2026. This is general information, not a tax calculation or a decision that a particular transfer qualifies for relief.
Separate the individual, the company and the trading name
Revenue distinguishes the individual sole trader's tax record from a company's Tax Reference Number. If the company needs VAT registration, arrange it for that company. Keeping a brand or customer account does not make the two taxpayers interchangeable.
Create a short identity schedule before changing software. Record the individual proprietor, the incorporated company's exact legal name and CRO number, and each relevant Revenue reference and registration status. Keep this privately with the adviser; do not send personal tax identifiers to every customer as part of a general announcement.

Check whether the company needs VAT registration
A new CRO number is not, by itself, a VAT registration. Revenue's rules consider the activity and applicable registration conditions. An exempt-only business is not in the same position as a taxable trader; receiving services or acquiring goods from abroad can create additional issues.
Ask the adviser to review the actual continuing trade, expected supplies, customer and supplier locations, and any transfer-of-business conditions. Do not assume the new company automatically gets a fresh period without registration simply because its own sales ledger starts empty.
If registration is not compulsory, a voluntary election may be relevant, but it needs a commercial and tax review. Compare customer requirements, purchase costs and ongoing administration. Avoid registering solely because a platform form has an optional VAT-number field.
Agree a sequence, not just one changeover date
Put at least three milestones on the plan: incorporation, the documented transfer or start of company trading, and the VAT-registration effective date. They may be connected, but they are not automatically the same event.
Revenue says registration generally takes effect from the date stated on the application, with backdating in certain circumstances by agreement. That is not permission to assume any preferred date will be accepted. Have the adviser distinguish compulsory registration from a voluntary election and confirm the position before launching new invoice templates.
Allow time for questions and evidence requests. If the planned handover is approaching and the application remains unresolved, ask for instructions on the transactions and documents affected. Do not borrow the individual's VAT number as a temporary workaround or assume that a pending application removes an existing tax obligation.
Prepare the company's application in the right identity
Revenue's new-company guidance requires a CRO number. An appointed tax agent must submit the registration online through ROS. For VAT, Revenue distinguishes TR2 company applications from TR1 applications for individuals and gives different routes where the business is not established in the State.
Prepare the company documents, intended activity, relevant start dates, expected turnover and evidence explaining the existing trade moving across. Ask which records are needed for your circumstances rather than sending an unstructured archive. Authorise the agent for the correct taxpayer; access to your personal record should not be mistaken for access to the LTD.
Keep the application reference, supporting information and confirmation together. Do not share a ROS password or digital certificate to speed up the process. Use the appropriate agent-authorisation procedure and agree who monitors Revenue correspondence.
Transfer of Business relief is not a transfer of the VAT number
Revenue's TOB overview concerns a business or independently operable part transferred in qualifying circumstances. A qualifying transfer is treated as no supply for VAT purposes. The relief is not established merely by selling selected equipment to a company you own.
The February 2026 manual says the treatment is mandatory where the conditions apply, and VAT incorrectly charged on such a transfer is not deductible. It also recognises that an accountable acquirer may not yet have received a registration number. Receipt of the number and the underlying accountable-person test are not identical.
Before assets move, obtain a review of the transfer agreement, what is included and each person's VAT position. Property, mixed activities or uncertain facts merit specific advice. Relief on the handover does not resolve the VAT treatment of the company's later sales.
Set up company invoices without rewriting the old history
Revenue's VAT-invoice requirements include the supplier's full name, address and registration number, a unique sequential number, and relevant dates and supply information. A new logo with the old proprietor's VAT details is not an adequate company invoice template.
Keep an export of the sole-trader ledger and issued documents before making changes. Create a clearly identifiable company invoice series as an administrative safeguard, with its own supplier identity and accounting records. There is no need to invent a rule that every business must restart numbering at one.
Test one example with your adviser before sending it to customers. Check the supplier, supply date, invoice date, tax treatment and payment instructions. Where registration is pending, obtain instructions on compliant documents and any later correction needed rather than guessing a VAT number or issuing misleading paperwork.
Schedule deposits, unfinished work and late customer payments
Build a list of transactions crossing the handover: deposits already received, work in progress, goods ordered but not delivered, unpaid invoices, customer refunds and recurring subscriptions. The date money reaches a bank account is not enough information to allocate every transaction correctly.
For each item, record the original contracting supplier, what was supplied or remains to be supplied, invoice references, payment dates and what the transfer agreement says. Give the adviser the actual documents and ask which taxpayer and return should deal with the item.
Take a fictional design business with a project deposit received before incorporation and work continuing afterward. It should not simply invoice the balance under whichever number is available first. The contract, transfer arrangements and relevant VAT timing rules need to be reviewed together. This example is a planning prompt, not a formula for splitting the VAT.
If a customer pays an old invoice into the company's account by mistake, flag the original reference for reconciliation. Changing the bank destination does not, by itself, settle the identity of the underlying supply.
Agree who handles older credit notes and corrections
Revenue's TOB manual says the transferor normally issues a credit note for relevant returns or price adjustments after the transfer. Revenue may accept a transferee-issued credit note case by case where no revenue loss results. Do not treat that exception as automatic permission for the LTD to issue every old credit note.
The credit-note rules require supplier details and a link to the original invoice. Separately, Revenue gives procedures for correcting invoices with incorrect prices or VAT rates. Preserve the original trail and have the adviser identify the appropriate issuer, document and return adjustment.
Give customer-service staff a simple escalation process. A refund request relating to an old order should reach the person holding the original invoice and transfer information, not disappear into the company's new sales system.
Do not assume incorporation cancels the old registration
Agree the appropriate cessation date and remaining filing obligations with the adviser or Revenue. Registering the LTD does not automatically cancel the individual's registration. Revenue warns that returns and estimated demands can continue when cancellation is not properly arranged.
If you originally elected to register voluntarily, check the separate cancellation rules. Revenue describes a potential repayment calculation using a review period limited to the shorter of the election's duration or three years before the cancellation application. Do not assume cancellation is simply an online switch with no tax consequences.
Tell the adviser if you retain another individual trade, keep business assets, continue making supplies or expect further adjustments. Closing one activity is not proof that every registration on your personal Revenue record should be ceased. Keep the cancellation confirmation and the agreed final-return timetable.
Retain accessible records for both sides of the handover
Do not delete the old account once the first company invoice has been issued. Keep the sales and purchase records, VAT returns, registration correspondence and transfer documentation accessible to the people responsible for the remaining work.
Revenue gives specific retention rules for matters such as claims, appeals, investigations and property, alongside requirements for paper and electronic records. Ask the adviser to document the applicable retention period and location for your records rather than assuming one date fits every file.
Make the handover usable: identify the last individual invoice, the first company invoice, outstanding balances, filed periods and items awaiting review. Retain exports in a readable format before ending a software subscription, and make sure an adviser change does not leave either taxpayer's records inaccessible.
A practical VAT handover checklist
Use this checklist before the first company transaction, not only when a return is due. Give each item an owner and an internal target. Where an answer is unresolved, identify what must be checked before the relevant transaction proceeds.
- Confirm the company is incorporated and identify both taxpayers correctly.
- Have the company's VAT-registration requirement and effective date reviewed.
- Agree the application route, agent authority and evidence needed.
- Document the asset-transfer review and any TOB conclusions.
- List deposits, unfinished work, unpaid invoices and possible refunds.
- Approve company invoice and credit-note procedures before use.
- Tell customers and suppliers which legal entity is trading from the agreed date.
- Update payment and platform details without overwriting earlier records.
- Agree the individual's cessation, remaining returns and payments separately.
- Retain confirmation of registrations, submissions, corrections and cancellation.
Choose support for the application and the wider transition separately
StartCompany.ie provides the company tax-registration support described on its service page, working with authorised partners. Review the included application work and total payable before ordering. If you are moving an existing trade, tell the team rather than presenting the company as a completely unrelated start-up.
The published registration service should not be treated as an automatic asset-transfer agreement, TOB opinion, final sole-trader return, bookkeeping migration or correction of historic invoices. Ask what additional work is needed and who will perform it. Agree responsibility for both the company and the individual's remaining obligations.
Revenue decides the registration outcome and may request further information; paying for support does not guarantee approval or a completion date. If the LTD has not yet been formed, compare formation packages separately. Incorporation does not itself guarantee VAT registration, banking, tax treatment, residency or immigration permission.
