Bulgarian Accounting & Bookkeeping in 2026: Rules, Fees, E-Invoicing

The basics

Every Bulgarian company — OOD, EOOD, AD — must keep double-entry accounting in accordance with the Bulgarian Accountancy Act and either National or International Financial Reporting Standards. There is no "dormant" or "micro-exempt" company in the Estonian sense: from day one, books must be kept monthly.

Who can do it

• In-house accountant — only viable above a certain size
• External licensed accountant — the standard solution for founders
• DIY — legally possible only for self-insured persons, not for companies

Accountants must hold professional qualifications and personal liability insurance.

The monthly cycle

1. Send all invoices and bank statements to your accountant by the 5th
2. Accountant books transactions, reconciles bank, computes VAT
3. VAT return (декларация по ЗДДС) filed by the 14th of the following month
4. Intrastat (for EU goods trade above thresholds) filed by the 14th
5. VIES recapitulative statement for EU B2B services filed by the 14th
6. Payroll computed; salaries paid; social/tax filings by the 25th

Annual obligations

• Annual corporate tax return — by 30 June
• Annual financial statements filed with the Commercial Register — by 30 September (mandatory publication)
• NSI statistical reports — by 30 June

Audit thresholds (2026)

A statutory audit is required if any two of three are exceeded for two consecutive years:

• Balance sheet total > BGN 4 million (~EUR 2.04m)
• Net revenue > BGN 8 million (~EUR 4.09m)
• Average employees > 50

Most founder-led companies stay below.

E-invoicing & SAF-T

Bulgaria is rolling out SAF-T reporting in phases through 2026-2028. Large taxpayers first; small companies later. E-invoicing for B2B is on the legislative roadmap but not yet mandatory in 2026. Choose accounting software (e.g. Microinvest, Plus Minus, Ajur) that's already SAF-T-ready.

Realistic monthly fees

Company profile	Fee range (EUR/month)
Dormant EOOD	50-100
Small EOOD, <20 transactions/mo, no VAT	100-150
Small EOOD, VAT-registered, EU clients	180-300
5-10 employees, EU + UK + US clients	350-700
Mid-size with VIES, Intrastat, payroll	700-1,500

Records retention

• Accounting records: 10 years
• Payroll and personnel files: 50 years (yes, fifty)
• VAT documents: 10 years

Bottom line

Bulgarian compliance is rule-based and predictable. The cost is among the lowest in the EU, but the cycle is monthly and deadlines are strict. Hire a proper accountant before you incorporate — not after.
