Annual Tax Filing for EOOD Owners: The Full Picture
If you own a Bulgarian EOOD (single-member limited liability company), you don't just file one tax return per year — you file several. The corporate tax return, your personal tax return, annual financial statements, and a statistical report for the NSI all have different deadlines and different requirements. Miss one, and you're looking at penalties and interest.
This guide covers every annual filing obligation for EOOD owners in Bulgaria for tax year 2025, filed in 2026. All figures are in EUR at the fixed conversion rate of 1 EUR = 1.95583 BGN.
What You Need to File: 4 Obligations
As an EOOD owner in Bulgaria, you have four distinct annual filing obligations. They are separate documents with separate deadlines:
- Annual CIT return (Годишна данъчна декларация по чл. 92 от ЗКПО) — your company's corporate income tax declaration, filed March 1 through June 30
- Annual financial statements (ГФО) — prepared by a certified accountant and published in the Commercial Register by September 30
- NSI annual activity report (Годишен отчет за дейността) — a statistical report filed together with the CIT return and forwarded to the National Statistical Institute
- Personal income tax return (Годишна данъчна декларация по чл. 50 от ЗДДФЛ) — your personal return covering dividend income and management salary, filed by April 30
Important distinction: The CIT return is filed by the company (your EOOD). The personal tax return is filed by you as an individual. They are separate filings with separate deadlines. Many first-time EOOD owners confuse them or assume the CIT return covers everything — it does not.
The CIT Return (Article 92, ЗКПО)
The annual corporate income tax declaration under Article 92 of the Corporate Income Tax Act (ЗКПО) is the main tax filing for your EOOD. It must be filed electronically using a qualified electronic signature (КЕП) between March 1 and June 30 of the year following the tax year.
What the CIT Return Contains
- Revenue: Total income from sales, services, and other sources for the tax year
- Expenses: Deductible operating costs — salaries, rent, supplies, professional services, depreciation
- Tax adjustments: Non-deductible expenses (entertainment, fines, certain provisions) are added back; specific deductions are applied
- Taxable profit: Revenue minus deductible expenses, plus/minus tax adjustments
- CIT calculation: 10% flat rate applied to the taxable profit
- Advance payments reconciliation: If your EOOD made quarterly or monthly advance CIT payments during the year, these are offset against the final tax liability. Any difference is either paid or refunded
- Deferred tax assets/liabilities: Timing differences between accounting and tax treatment of certain items (e.g., provisions, depreciation differences)
How CIT Is Calculated: A Simple Example
Suppose your EOOD had EUR 80,000 in revenue and EUR 50,000 in deductible expenses in 2025:
| Item | Amount |
|---|---|
| Total revenue | EUR 80,000 |
| Deductible expenses | EUR 50,000 |
| Non-deductible expenses added back | EUR 2,000 |
| Taxable profit | EUR 32,000 |
| CIT at 10% | EUR 3,200 |
| Less: advance payments made during 2025 | EUR 2,400 |
| Remaining CIT to pay | EUR 800 |
Advance CIT payments: EOODs with net revenue above EUR 153,388 (BGN 300,000) in the prior year must make quarterly advance CIT payments. EOODs with net revenue above EUR 1,533,876 (BGN 3,000,000) must make monthly advance payments. If your revenue is below EUR 153,388, advance payments are voluntary. Underpaying advance payments by more than 20% triggers interest.
The 1% Early Filing Discount
Bulgaria rewards early filing with a small but meaningful tax discount. Under Article 92 of ЗКПО, if you meet all three conditions by March 31, you receive a 1% reduction of your annual corporate tax:
- File the annual CIT return electronically by March 31
- Submit the NSI annual activity report together with it by March 31
- Pay the full CIT due by March 31
The discount is capped at EUR 511 (BGN 1,000). In practice:
- CIT of EUR 10,000 → discount of EUR 100 (1%)
- CIT of EUR 30,000 → discount of EUR 300 (1%)
- CIT of EUR 60,000 → discount capped at EUR 511 (not EUR 600)
- CIT of EUR 100,000 → discount still EUR 511 (cap applies)
Is it worth it? For most EOODs, absolutely. If your accountant has the books closed by March, filing 3 months early costs you nothing and saves up to EUR 511. The only reason to delay is if your accounts aren't ready — which is an accountant performance issue, not a strategic decision.
Need Help Filing Your EOOD Tax Returns?
We coordinate with your accountant to ensure all filings are correct and on time — CIT return, GFO, personal return, and everything in between.
Get Filing Support →Annual Financial Statements (ГФО)
The annual financial statements (Годишен финансов отчет / ГФО) are a separate obligation from the CIT return. While the CIT return goes to the NRA, the ГФО must be published in the Commercial Register (Търговски регистър) managed by the Registry Agency.
What the ГФО Contains
- Balance sheet (Баланс) — assets, liabilities, and equity at year-end
- Income statement (Отчет за приходите и разходите) — revenue, expenses, and profit/loss for the year
- Notes to the financial statements — accounting policies, significant transactions, contingent liabilities
- Cash flow statement — if required by the size of the company (most small EOODs are exempt)
Key Details
- Deadline: September 30 of the following year (September 30, 2026 for tax year 2025)
- Filed via: Application G2 to the Commercial Register, electronically
- Prepared by: Your accountant — must be a certified accountant for companies exceeding certain thresholds
- Penalties for non-publication: EUR 100 to EUR 1,534 (BGN 200 to BGN 3,000) for the responsible official; EUR 256 to EUR 1,534 for the company
Companies with no activity: Even if your EOOD had zero revenue in 2025, you must still file a declaration of inactivity with the Commercial Register by June 30, 2026. Failure to file this carries a penalty of up to EUR 511 (BGN 1,000). This catches many dormant companies off guard.
Your Personal Tax Return (Article 50, ЗДДФЛ)
As the owner and manager of an EOOD, you likely receive income in two ways: a management salary and dividends. Both must be declared on your personal income tax return, filed by April 30.
Management Salary
If you receive a salary (under a management contract or employment contract), your EOOD withholds income tax at source — 10% flat rate. This is reported in Annex 1 of the personal return. If the EOOD was your only employer and tax was correctly withheld, you may not owe additional tax on salary income.
Dividend Income
Dividends distributed by your EOOD to you as a natural person are subject to a 5% withholding tax at source (for dividends distributed in respect of tax year 2025). The EOOD withholds and remits this tax. On your personal return, dividend income is reported in Annex 6. Because the tax is final (withheld at source), it doesn't increase your personal tax bill — but it must still be declared.
Social Security Reconciliation (Table 1 & Table 2)
If you are self-insured as the EOOD manager (which is the standard arrangement for single-owner EOODs), you must attach Table 1 and Table 2 to your personal return. These tables reconcile your advance social security contributions paid during 2025 against your actual insurable income:
- Table 1: Determines your final insurable income for each month based on actual income earned
- Table 2: Calculates the difference between advance contributions already paid and the amount actually due
- If you underpaid, you owe the difference by April 30
- If you overpaid, the excess is offset against future contributions or refunded
Early filing discount for personal returns: If you file your personal return electronically and pay any tax due by March 31, you receive a 5% discount on the personal income tax due (under Article 53(6) of ЗДДФЛ). This is separate from the 1% CIT discount — and more generous. On a EUR 2,000 personal tax bill, that's EUR 100 saved.
First Year Filing for Your EOOD?
The first annual filing is the most confusing. We walk you through every obligation — what to file, when, and what documents your accountant needs from you.
Book a Free Consultation →Timeline: What to File When
Here is the complete annual filing calendar for an EOOD owner, covering all obligations from January through September:
| When | What | Where | Notes |
|---|---|---|---|
| Jan – Feb | Close the books for 2025 | Your accountant | Finalize revenue, expenses, depreciation schedules, provisions |
| Mar 1 | CIT return filing window opens | NRA portal (portal.nra.bg) | Earliest you can file the annual CIT return |
| Mar 31 | Early filing deadline for 1% CIT discount | NRA portal | File CIT return + NSI report + pay tax by this date for 1% off (max EUR 511) |
| Mar 31 | Early filing deadline for 5% personal tax discount | NRA portal | File personal return + pay tax by this date for 5% off personal income tax |
| Apr 30 | Personal income tax return deadline | NRA portal | Includes management salary, dividends, Table 1 & Table 2 SS reconciliation |
| Apr 30 | Dividend WHT quarterly declaration | NRA portal | If dividends were distributed in Q1 2026, declare by end of April |
| Jun 30 | CIT return final deadline | NRA portal | Last day to file the annual corporate tax return and pay CIT |
| Jun 30 | Declaration of inactivity (if applicable) | Commercial Register | Only for EOODs with no activity in 2025 |
| Sep 30 | Publish ГФО in Commercial Register | Registry Agency | Application G2, filed electronically. Penalties for non-publication. |
Pro tip: The practical best practice is to close the books in January-February, file everything by March 31, and collect both discounts. Your accountant should be driving this timeline. If they consistently file in May or June, you are losing money every year.
Your Accountant Handles Most of It
In practice, Bulgarian EOOD owners rarely touch the NRA portal themselves. Your accountant handles nearly all of it — and this is standard, not exceptional. Here is the division of responsibilities:
What Your Accountant Does
- Prepares and files the CIT return electronically using their own КЕП (qualified electronic signature) under a power of attorney
- Prepares the annual financial statements (ГФО) and files Application G2 with the Commercial Register
- Submits the NSI annual activity report together with the CIT return
- Prepares and files your personal tax return — including Table 1 and Table 2 for SS reconciliation — again using their КЕП under power of attorney
- Files quarterly dividend WHT declarations when dividends are distributed
- Calculates and reconciles advance CIT payments against the final tax liability
What You Provide
- Invoices — both issued and received, monthly or as they occur
- Bank statements — monthly, or give your accountant read-only access to the business account
- Contracts — any new client or supplier agreements during the year
- Dividend distribution minutes — a protocol of the sole owner's decision to distribute dividends (your accountant usually drafts this)
- Power of attorney — authorizing the accountant to file on behalf of you and the company
- Personal information — if your personal circumstances changed (new child, foreign income, property sale)
КЕП requirement: Since 2018, all corporate tax returns in Bulgaria must be filed electronically using a qualified electronic signature (КЕП). Your accountant has their own КЕП and files under power of attorney. You do not need to purchase your own КЕП unless you want to access the NRA portal directly. КЕП providers include B-Trust, Evrotrust, and InfoNotary (EUR 15-30/year).
Looking for a Reliable Accountant?
We work with vetted accounting firms that serve international EOOD owners. English-speaking, deadline-driven, and familiar with cross-border situations.
Get Accountant Referral →"I've been in Bulgaria for a year and nobody told me about these filings." This is more common than you'd think. Many EOOD owners focus on the company setup and assume the accountant handles everything automatically. But the accountant needs your invoices and bank statements on time, needs a power of attorney to file on your behalf, and needs to know about your personal income situation (foreign income, dividends from other sources, property sales). If you don't communicate proactively, filings get delayed or submitted incorrectly.
"My EOOD had no activity — do I still need to file?" Yes. Dormant companies must still file a CIT return (showing zero activity) and a declaration of inactivity with the Commercial Register by June 30. Failure to file the inactivity declaration carries a penalty of up to EUR 511. The ГФО publication requirement also applies — even with zero revenue.
"Can I file everything myself without an accountant?" Technically, yes — but realistically, no. The CIT return requires knowledge of Bulgarian tax law, IFRS/national accounting standards, and the NRA portal interface (which is in Bulgarian). The annual financial statements must be prepared according to applicable accounting standards. For an EOOD with real activity, professional accounting is not optional — it's a practical necessity.
