Bulgaria StartUp Visa Tax and Business Setup

For Bulgaria StartUp Visa founders, the certificate file and the business file need to stay aligned. The founder applies on the basis of a high-tech or innovative project; company registration, UIC records, tax registration, VAT, accounting, contracts, and founder work should support that project.

For route fit, see the main Bulgaria guide. For certificate evidence and residence sequencing, use the timeline and documents guide.

Setup Snapshot

Area	Why It Matters
Bulgarian company form	Startup evidence should match the approved high-tech/innovative project
Commercial Register	The Registry Agency maintains the Commercial Register
UIC and tax registration	Commercial Register entry triggers official registration for tax purposes
VAT	Registration can be mandatory or optional depending on turnover and activity
Corporate tax	Ministry of Finance states Bulgaria’s corporation tax rate is 10%
Accounting	Supports tax compliance, funding, customers, and renewal
Founder work records	Shows the business is not passive ownership

Company Registration

The Bulgarian Point of Single Contact states that the Commercial Register is maintained by the Registry Agency to the Ministry of Justice. The procedure for registering a company is the same for Bulgarian and foreign citizens, and applications can be submitted on paper or electronically where the electronic-signature rules are met.

Applications and attachments are submitted in Bulgarian. Documents in another official EU language can be submitted with a certified Bulgarian translation.

The most common legal forms include sole proprietor, sole owner limited liability company, limited liability company, sole owner joint-stock company, and joint-stock company. For many startup cases, a limited liability company structure may be the first form to analyse, but investors, liability, governance, regulated activity, tax, and immigration facts can change that conclusion.

UIC And Tax Registration

The Commercial Register process matters beyond company law. The Point of Single Contact states that after entry in the Commercial Register, ex officio registration of the merchant is made for National Insurance Institute contribution purposes and in the National Revenue Agency register for tax purposes.

For a StartUp Visa founder, the key question is not just whether the company exists. The company records should match the approved project: founders, ownership, product, contracts, research, revenue, bank records, invoices, expenses, payroll, and accounting should all point to the same business.

VAT

Bulgaria’s VAT registration can be mandatory or optional. The National Revenue Agency’s Bulgarian VAT page states that from January 1, 2026, established taxable persons have a mandatory registration obligation when annual turnover in Bulgaria exceeds the national threshold of EUR 51,130.

Older Ministry of Finance VAT material may still show the prior BGN 100,000 threshold. Because Bulgaria adopted the euro on January 1, 2026, applicants should check the current NRA page and live VAT registration instructions before invoicing.

Corporate Tax

The Ministry of Finance states that Bulgaria’s corporation tax rate is 10%, assessed on tax profit. Taxable persons submit an annual corporate tax return for the tax financial result and annual corporation tax due, with an annual activity report where required.

For founders, corporate tax is only one part of the setup. Personal tax, payroll, social security, withholding tax, VAT, accounting standards, transfer pricing, and cross-border customer contracts may all matter.

Renewal Evidence

Keep Current	Why
StartUp Visa certificate and ministry correspondence	Shows the approved project basis
Commercial Register records	Confirms company setup and maintenance
Ownership and management records	Shows founder involvement
UIC, tax, VAT, and accounting records	Supports compliance
Product, research, customer, and contract evidence	Supports the innovation story
Funding, bank, and runway records	Supports continuity
Payroll and contributor records	Supports real operations where relevant

Common Setup Problems

Problem	Why It Matters
Registering a generic company after certificate approval	Company setup should match the approved project
Treating the certificate as the whole immigration process	Residence is separate
Ignoring VAT before invoicing	VAT errors can damage the compliance record
Mixing startup work with unrelated freelancing	Work story and route basis can diverge
Passive ownership	StartUp Visa is for active innovative/high-tech business development
