The Transition That Most Freelancers Get Wrong
You started as a freelancer in Bulgaria because it was fast, cheap, and simple. Now your income has grown, you need liability protection, or clients are asking for a legal entity. Time to switch to an EOOD (single-member limited liability company). The problem: most guides treat this as "register an EOOD and you are done." In reality, the transition involves eight distinct steps across three different government bodies, and getting the sequence wrong creates tax headaches that take months to unwind.
This guide covers the complete process: when the switch makes financial sense, the exact steps in the right order, what happens to your VAT registration, how to handle client contracts, and the social security rules during the overlap period. Every procedure and deadline referenced here has been verified against current Bulgarian law and NRA requirements.
When to Make the Switch
The decision to convert from freelancer to EOOD is driven by three factors: income level, liability needs, and growth plans. For a detailed numerical comparison at six income levels, see our freelancer vs EOOD income threshold analysis. Here is the summary framework:
Income Threshold
The freelancer's 7.5% effective income tax looks better than the EOOD's 15% combined rate (10% CIT + 5% dividend withholding). But that comparison ignores social security. Freelancers owe approximately 31.3% in social security contributions on their actual net income (after the 25% automatic deduction), recalculated annually. EOOD owners pay social security only on their minimum salary of EUR 620.20 per month. Above approximately EUR 3,000/month in gross income, the EOOD typically delivers higher take-home pay once you account for the social security reconciliation.
Liability Protection
As a freelancer (svobodna profesiya), you are personally liable for all obligations arising from your activity — with your entire personal estate. An EOOD limits liability to the company's assets only. If you are taking on larger contracts, working with enterprise clients, or operating in any area with litigation risk, the EOOD structure becomes essential regardless of tax math.
Growth Plans
An EOOD can hire employees, retain earnings at just 10% CIT (deferring the 5% dividend tax), build a sellable business asset, and present a professional legal entity to clients and partners. A freelancer cannot do any of these things. If you plan to scale beyond solo work, the EOOD is the only viable path. For more on running multiple entities, see our guide on owning two companies in Bulgaria.
Step-by-Step: The Transition Process
The full transition takes 3-4 weeks if executed efficiently. Here are the eight steps in the correct sequence:
Step 1: Register the EOOD (3-5 business days)
Your lawyer prepares the incorporation documents and files with the Trade Registry at the Registry Agency. Required documents: articles of association, specimen signatures (notarized), proof of minimum capital deposit (EUR 1), and a registered address. For EU citizens, this can be done entirely remotely via Power of Attorney. Cost: EUR 700-999 + VAT (lawyer fees). Trade Registry filing fee: EUR 55 (online) or EUR 80 (paper). Registered address is a separate service.

Step 2: Obtain an Electronic Signature (KEP)
A KEP (qualified electronic signature) is mandatory for operating an EOOD in Bulgaria. You need it to file tax returns, submit declarations to the NRA, and publish annual financial statements. Cost: EUR 25-50 per year. Processing: 1-3 business days. Providers include B-Trust, Evrotrust, and InfoNotary.
Step 3: Open a Corporate Bank Account (~1 week)
Visit a Bulgarian bank with your Trade Registry certificate, articles of association, and personal ID. KYC processing takes approximately one week. Opening fees range from EUR 100-500 depending on the bank. DSK Bank and UniCredit Bulbank are the most common choices for foreign owners due to English-language support and online banking. Your personal freelancer bank account remains separate — the EOOD needs its own dedicated corporate account.
Step 4: Register as EOOD Manager with the NRA
File an OKD-5 declaration with the NRA declaring the commencement of activity as a self-insured manager of the EOOD. This must be done within 7 days of beginning activity. Choose your insurance base (minimum EUR 620.20/month) and whether you will insure for general sickness and maternity (optional but recommended). Engage an accountant to handle double-entry bookkeeping from day one.
Step 5: Transition Client Contracts to the EOOD
Begin invoicing through the EOOD. Notify existing clients that future work will be billed through your new company. Sign new contracts or addenda substituting the EOOD as the contracting party (more on this in the client contracts section below).
Step 6: File NRA Cessation for Freelancer Activity
Once all client work has been migrated to the EOOD, file an OKD-5 declaration with the NRA declaring cessation of your freelancer activity. Deadline: within 7 days of the cessation date. Penalty for missing the deadline: BGN 50-500 fine. The declaration can be submitted at any NRA office, through the NRA Electronic Services Portal, by e-mail, or through the Secure Electronic Service System (SSEV).
Step 7: Deregister from BULSTAT
File a deregistration application with the Registry Agency to remove your freelancer entry from the BULSTAT Register. The registration official processes the deletion within 3 working days. State fee for BULSTAT deregistration: approximately EUR 5.
Step 8: Handle VAT and File Final Returns
If you were VAT-registered as a freelancer, initiate VAT deregistration (see the VAT section below). File your final annual personal income tax return by April 30 of the following year, covering your freelancer income for the active period. Complete the social security annual reconciliation (Table 1 and Table 2). Any additional social security owed from the reconciliation is due by April 30.
Running Both Simultaneously
Yes, you can operate as a freelancer and own an EOOD at the same time. They are two separate legal capacities: you as a natural person (freelancer) and the EOOD as a separate legal entity. Bulgarian law fully recognizes this dual status.
Most people run both structures in parallel for 1-2 months during the transition. You invoice existing clients through the freelancer registration while onboarding new clients through the EOOD. There is no legal requirement to close one before opening the other.
Social Security During the Overlap
When you earn income from multiple activities, social security contributions are calculated on the aggregate of all income sources. The total monthly insurable income cannot exceed the statutory maximum of EUR 2,111.64 (2026). In practice, if you are paying social security as the EOOD manager on the minimum salary (EUR 620.20), your freelancer income increases the insurable base up to the cap during the overlap period. The annual reconciliation (filed with your personal income tax return) settles any difference.
Priority of insurance: Under Art. 6(11) of the Social Security Code (KSO), when a person is insured on multiple grounds, social security contributions are calculated in a specific priority order: (1) employment income, (2) self-insured person income (which includes both your EOOD manager role and freelancer activity). The combined base from all sources cannot exceed the monthly maximum.

Get StartedClosing Your Freelancer Registration
Closing a freelancer registration involves three separate filings. Miss any of them and you will continue to owe social security contributions or face penalties.
1. NRA Cessation Declaration (OKD-5)
File a modified OKD-5 declaration with the NRA indicating the date of cessation of your freelancer activity. This is the same form used to register the activity — it serves both purposes. The deadline is 7 days from the cessation date. Filing methods: in person at any NRA territorial directorate, via the NRA Electronic Services Portal (requires KEP), by e-mail with electronic signature, or through SSEV.
Once the NRA processes this declaration, your obligation to pay monthly social security advances as a freelancer ends as of the cessation date.
2. BULSTAT Deregistration
File a deregistration application with the Registry Agency (Agentsiya po vpisvaniyata). The registration official issues a decision within 3 working days of submission. State fee: BGN 15 (electronic) or BGN 30 (paper). You can file in person at any Registry Agency office or electronically via the BULSTAT portal.
3. Final Tax Return and Social Security Reconciliation
File an annual personal income tax return (by April 30 of the following year) covering your freelancer income for the portion of the year you were active. This return must include:
- Table 1 — determination of the final annual insurable income (reconciliation of advance social security payments against actual income)
- Table 2 — calculation of additional social security contributions owed (if actual income exceeded your declared monthly base)
- Declaration 6 — data on outstanding social security contributions, due by April 30
Any additional social security owed from the reconciliation must be paid by April 30. If you cease activity mid-year, you still owe the reconciliation for the active months only.

Book a Free ConsultationVAT Considerations
VAT is one of the most commonly misunderstood aspects of the freelancer-to-EOOD transition. The key principle: your freelancer VAT number cannot be transferred to the EOOD. They are separate legal entities, each requiring independent VAT registration.
If You Are VAT-Registered as a Freelancer
When you cease your freelancer activity, you must initiate VAT deregistration with the NRA. The deregistration triggers a final VAT return and may require you to account for VAT on any remaining assets or inventory. The process takes approximately 1 month from filing.
If the EOOD Needs VAT Registration
The EOOD applies for its own VAT number independently. Mandatory registration is triggered when the EOOD's taxable turnover exceeds EUR 51,130 within a calendar year. You can also apply for voluntary VAT registration at any time — useful if you primarily serve B2B clients in the EU (reverse charge mechanism). The EOOD's VAT registration is entirely separate from your personal freelancer VAT history.
Timing matters: If you deregister your freelancer VAT and the EOOD is not yet VAT-registered, there will be a gap during which you cannot charge or reclaim VAT. Plan the VAT transition carefully — especially if you have ongoing contracts that include VAT. Consider registering the EOOD for VAT before deregistering the freelancer, so there is no gap in coverage.
Client Contracts: You Need New Agreements
This is the step most people underestimate. Your existing client contracts are between your clients and you as a natural person. The EOOD is a different legal entity with a different identification number, different bank account, and potentially a different VAT number. Existing contracts cannot automatically transfer to the EOOD.
What You Need to Do
- New contracts or addenda — sign new service agreements with the EOOD as the contracting party, or execute addenda to existing contracts substituting the EOOD for you personally
- Updated invoicing details — new company name, EIK (company identification number), registered address, corporate bank account (IBAN), and VAT number if applicable
- Client notification — inform each client in writing of the change. Provide the EOOD's registration details and new banking information
- Transition period — for ongoing projects, you may complete current milestones under the freelancer contract and begin the next phase under the EOOD contract
Most clients accept this transition without issue — it is standard practice. Prepare a template notification letter and a standard EOOD service agreement to streamline the process.
Common Mistakes to Avoid
1. Switching Mid-Year Without Planning
A mid-year switch creates split-year accounting complexity. You file a personal income tax return for freelancer income and a separate corporate tax return for the EOOD — two returns, two accountants (potentially), two sets of books. January 1 is the cleanest transition date. If you must switch mid-year, coordinate with your accountant before starting.
2. Forgetting the Social Security Reconciliation
Closing the freelancer registration does not eliminate your obligation for the annual reconciliation. If you operated as a freelancer for any portion of the year and your actual income exceeded your declared monthly insurance base, you owe additional contributions. This is calculated in Table 1 and Table 2 of the annual tax return and is due by April 30 of the following year. Failure to include it is treated as an incorrect tax return.
3. Not Deregistering from BULSTAT
Filing the NRA cessation (OKD-5) is not enough. You must also deregister from BULSTAT at the Registry Agency. Leaving an active BULSTAT registration means you may continue to receive correspondence and potentially be considered an active entity for administrative purposes.
4. Assuming the VAT Number Transfers
It does not. The freelancer's VAT registration is personal. The EOOD needs its own. Failing to deregister the freelancer's VAT while no longer issuing invoices through it can trigger NRA inquiries.
5. Not Opening a Corporate Bank Account Before Starting
You cannot invoice through the EOOD until you have a corporate bank account to receive payments. Bank account opening takes approximately 1 week for KYC. Start the bank application immediately after receiving the Trade Registry certificate — do not wait until you have your first EOOD invoice ready.
