Moving from sole trader to limited company is not a change of label on the same business. You first incorporate a new Irish company. You then decide which assets, contracts, employees, registrations and trading activities move from you personally to that separate legal entity.
A clean transition needs one agreed cutover date and coordination between the CRO formation, Revenue registrations, banking, customer contracts, invoicing and bookkeeping. Where the business has valuable goodwill, property, equipment, loans, employees or VAT history, tax and legal advice should come before the transfer documents are signed.
Quick answer
Incorporate the LTD, choose a realistic transfer date, document the assets and liabilities moving to it, arrange new company tax and bank accounts, update contracts and registrations, then complete the sole trader's final returns. Do not simply change the name on invoices and assume everything transferred.
Conversion Is Really a Business Transfer
A sole trader and the owner are the same legal person. An incorporated LTD is a new person with its own company number, tax reference, bank account, contracts, records and filing deadlines. The LTD does not automatically inherit the sole trader's assets, debts, tax registrations or agreements.
This distinction protects both sides of the cutover. Customers should know which entity supplies them, suppliers should know who owes payment, and Revenue records should show which person earned each period's income. A written transfer plan is especially important if trading continues without interruption.
Before You Incorporate: Plan the Transfer
Begin with a current balance sheet or practical inventory of the business. List what the sole trader owns, owes and has promised. Then identify whether each item will transfer, remain personally owned and licensed to the company, be settled before the cutover, or require another party's consent.
| Area | Questions before the cutover | Typical action |
|---|---|---|
| Assets | What are stock, equipment, vehicles, goodwill and IP worth? | Value and document transfer or licence |
| Liabilities | Which debts can the company legally assume? | Get lender or creditor agreement where needed |
| Contracts | Do terms permit assignment? | Assign, novate or replace agreements |
| Tax | Could CGT, VAT or Stamp Duty arise? | Obtain advice before signing |
| Employees | Does TUPE apply? | Plan information, consultation and payroll |
| Trading name | Will the company use the same public brand? | Check and register RBN1B where required |
| Cash flow | When will company banking and payments be ready? | Coordinate banking and merchant accounts |
Step 1: Choose the Company Structure and Cutover Date
Most owner-managed businesses choose a private company limited by shares. Decide who will own the shares, who will act as director and who will be secretary. A one-director LTD is permitted, but the sole director cannot also be the company secretary. The company also needs a physical registered office in Ireland.
Choose a cutover date after allowing time for incorporation, company banking, Revenue registration and any contract consents. Avoid backdating invoices or pretending the company supplied work before it legally existed. Keep evidence showing which unfinished work, deposits, debtors and creditors belong on each side of the date.
Read the one-person LTD guide and the business name versus limited company guideif the structure is not yet settled.
Step 2: Incorporate the New Irish LTD
The CRO application uses Form A1 and an LTD constitution. It records the company name, registered office, director, secretary, subscriber and shares, principal activity, NACE code and Irish activity location. The proposed name should be searched against companies, business names and trade marks before filing.
Do not begin issuing company invoices merely because the application has been submitted. Wait until the CRO has incorporated the company and issued its Certificate of Incorporation. The company number and full legal details can then appear on invoices, contracts, websites and business correspondence.
StartCompany.ie formation begins at EUR240 with the CRO fee, company name check, constitution, Certificate of Incorporation and share certificates included. Compare formation packages before filing.
Step 3: Value and Document the Business Transfer
Prepare a transfer agreement or other suitable documents describing what the company acquires and the consideration it gives. Depending on the business, transferred items may include stock, tools, equipment, vehicles, customer lists, domain names, websites, software, intellectual property, goodwill and work in progress.
Use supportable market values. The accounting entries, tax treatment and share value should tell the same story. If the founder keeps an asset personally and allows the company to use it, document the licence, lease or loan arrangement and consider the connected-person and benefit implications with an adviser.
Section 600 Incorporation Relief and Capital Gains Tax
Transferring goodwill, premises or other chargeable assets can create a disposal for Capital Gains Tax purposes. Section 600 of the Taxes Consolidation Act 1997 may defer part of the gain when a person transfers a business as a going concern to a company wholly or partly in exchange for shares.
Revenue guidance says the business must generally transfer with the whole of its assets, or all assets other than cash. Relief applies only to the proportion of consideration taken as shares. Cash, a credit on a director's loan account and some liabilities assumed by the company can count as non-share consideration and may leave part of the gain immediately chargeable. The transfer must be for bona fide commercial reasons and not part of tax avoidance.
This is a deferral mechanism, not a promise that no tax will ever arise. The deferred gain reduces the base cost of the shares for a future disposal. The exact transfer agreement and valuations matter, so have an accountant or tax adviser review the transaction before execution.
VAT and Transfer of Business Relief
The sole trader's VAT registration does not become the company's VAT number. The company is a different taxable person and should obtain its own registration where required or where a voluntary application is appropriate.
Revenue's Transfer of Business provisions can treat a qualifying transfer of assets as no supply for VAT purposes. The relief is intended to avoid unnecessary VAT funding where the purchaser carries on the business and meets the relevant conditions. It is not automatic for every sale of equipment or selected assets. Property, capital goods, partial transfers and mixed activities require particular care.
Keep the sole trader VAT registration active until all returns and liabilities through cessation are handled. Revenue warns that return forms and estimated demands can continue if a registration is not properly cancelled. See theVAT number guide for new companies.
Stamp Duty and Other Transfer Taxes
Stamp Duty can arise on written instruments transferring land, buildings, certain property, leases or other assets. The result depends on what transfers, the instrument used, consideration and available reliefs. Incorporation itself does not make every asset transfer free from Stamp Duty.
Stock, depreciating equipment, goodwill and property may also have different Income Tax, Capital Allowances and CGT consequences. A business with valuable assets should obtain a transaction-specific tax calculation rather than use a generic journal entry after the event.
Step 4: Transfer or Replace Contracts
Review customer contracts, supplier terms, premises leases, vehicle finance, loans, grants, software subscriptions, merchant services and licences. An assignment transfers rights, while a novation can move rights and obligations with the other party's agreement. Some contracts prohibit transfer or require written consent.
A debt owed by the sole trader does not disappear because the company starts trading. Likewise, a customer does not automatically owe the company money originally invoiced by the individual. Record whether receivables are assigned, collected personally or credited through the transfer price. Personal guarantees may continue even after a contract moves.
Step 5: Keep or Change the Trading Name
Incorporating a similar company name does not automatically transfer the old business-name registration. If the LTD trades under a name other than its full legal company name, the company normally registers the trading name using Form RBN1B. The individual's old registration can be ceased using Form RBN3 when that person no longer trades under it.
The CRO currently lists an electronic fee of EUR20 for a new business-name registration and no electronic fee for a cessation. Registration does not create trade mark protection, so review ownership of the brand, domain and social accounts as part of the asset transfer.
Step 6: Open Company Banking and Payment Accounts
The company should receive its own sales income and pay its own expenses. Open a company bank account and update card processors, direct debits, standing orders, ecommerce gateways and finance platforms. Banks and payment providers may request the incorporation certificate, constitution, ownership details, director identification and business evidence.
Do not continue mixing personal and company transactions for convenience. If the founder pays a company cost personally or transfers money to the company, record it correctly through expenses, share capital or the director's loan account. Use our Irish business bank account guide.
Step 7: Register the Company With Revenue
Revenue issues the company its own tax reference number. Register the relevant tax heads, which may include Corporation Tax, employer PAYE, VAT and RCT. Revenue states that a Statement of Particulars is required within 30 days after an Irish incorporated company begins trading. Director salary and fees are processed through PAYE.
The company does not inherit the individual's tax history or ROS certificate. Coordinate agent authorisation and company ROS access. If the business needs tax clearance for contracts or grants, check how the new legal entity must establish it.
Step 8: Complete the Sole Trader's Final Tax Work
Prepare final accounts from the beginning of the accounting period to the transfer date. The individual remains responsible for Income Tax, PRSI, USC, VAT, PAYE or RCT returns and payments arising before cessation. Incorporation does not transfer those liabilities to the company unless a legally effective arrangement says otherwise, and it does not release the individual from Revenue obligations.
Revenue's Manage Tax Registrations function on ROS can cease the applicable registrations. Taxpayers who cannot use ROS may use Form TRCN1. Do this only after confirming the correct cessation date and outstanding filing position. Keep the underlying sole-trader books and transfer records for the statutory retention period.
Step 9: Handle Employees and Payroll Correctly
Where an undertaking transfers from the individual employer to the company, the European Communities (Protection of Employees on Transfer of Undertakings) Regulations 2003 may apply. The WRC explains that existing employment rights and accrued service generally transfer to the new employer when the rules apply.
Both employers can have information and consultation obligations. Where reasonably practicable, specified information is given to employee representatives at least 30 days before the transfer and in any event in good time. Payroll, pension, leave balances, employment permits and insurance should be checked with employment and payroll advisers.
Step 10: Update Customers, Suppliers and Public Details
Tell stakeholders the exact date from which the LTD supplies goods or services. Update quotations, engagement letters, terms, invoices, website legal notices, email footers, insurance, licences, data-protection notices, privacy information and supplier onboarding records. Customers should not have to guess whether they contracted with the individual or company.
Display the full company name, company number, legal form and registered office where required. If personal data moves to the company, document the controller change and ensure there is a lawful basis, appropriate notice and secure transfer.
First-Year Obligations for the New LTD
Incorporation begins a fresh compliance calendar. Register the company's beneficial owners with the RBO within five months. Prepare the first CRO annual return for the date six months after incorporation. Financial statements are normally not attached to that first return, but filing it on time is essential.
Set up bookkeeping from the first company transaction, preserve board and transfer approvals, maintain statutory registers and schedule Corporation Tax, payroll and VAT deadlines. The old sole-trader records and the new company books should reconcile to the transfer agreement.
Does the New Company Qualify for Start-Up Corporation Tax Relief?
Do not assume it does. Revenue excludes a trade previously carried on by another person, and activities that were previously another person's trade or profession, from the qualifying-trade rules for start-up company relief. A company succeeding to the founder's existing sole-trader activity may therefore be outside the relief even though the company itself is newly incorporated.

Frequently Asked Questions
Can I convert a sole trader business into a limited company in Ireland?
Yes, but there is no automatic legal conversion. You incorporate a new company and then transfer the business operations, assets, contracts and registrations that should move. The sole trader and the company are different legal and taxable persons.
Can I keep the same business name after incorporating?
Usually, subject to company-name, business-name and trade mark checks. If the company trades under a name other than its full corporate name, it normally registers that trading name using Form RBN1B. The individual's old business-name registration may need to cease using Form RBN3.
Does my sole trader VAT number transfer to the company?
No. The company is a separate person and normally needs its own tax registrations. The sole trader's VAT registration should be ceased only when appropriate, and the company should register where required. Transfer of Business VAT relief may apply to qualifying asset transfers.
Will transferring my business to a company trigger Capital Gains Tax?
It can. Section 600 incorporation relief may defer some CGT when a business is transferred as a going concern with its assets to a company wholly or partly for shares. The conditions and the mix of shares, cash, loans and liabilities matter, so obtain tax advice before signing the transfer.
Do customer and supplier contracts automatically move to the company?
Usually not. Contracts may need assignment, novation or counterparty consent. Leases, finance agreements, licences, merchant accounts and insurance policies should be reviewed individually before the company starts performing under them.
What happens to employees when a sole trader incorporates?
The Transfer of Undertakings Regulations may apply where a business transfers to a new employer. Existing employment rights and service can transfer, and both employers may have information and consultation duties. Obtain employment-law advice before the change date.
When should I stop issuing invoices as a sole trader?
Use a documented cutover date after the company has been incorporated and is ready to trade. Sole-trader work before that date and company work after it should be invoiced, banked and recorded by the correct legal person.
Do I still have to file a final sole trader tax return?
Yes. Incorporating does not erase the individual's existing filing and payment obligations. Complete the final sole-trader accounts and Form 11, settle liabilities and cease relevant registrations through ROS only when the old trade has genuinely ended.
