Bulgaria's labour rules catch most foreign employers off guard
EOR speed, flat tax, and length of service pay define your hiring baseline
You can hire in Bulgaria legally without a local entity by using an employer of record, which means you can move from offer accepted to day one in days rather than months.
Bulgaria's flat 10% personal income tax and employer contributions of 18.92% to 19.62% make total employment cost predictable from the first offer letter, which is exactly what your finance team needs to model headcount accurately.
Length of service pay is a mandatory incremental benefit unique to Bulgaria: at least 0.6% of monthly salary per year of service and professional experience, accruing from both current and prior employers in similar roles. Every offer you make must account for it, and Oyster's in-house compliance specialists review every Bulgaria employment contract before it reaches your new hire, so nothing slips through.
Bulgaria's flat 10% tax and capped contributions make costs predictable
Key facts and employment figures for Bulgaria
Bulgaria sits in Eastern Europe, operates on EET (UTC+2) with EEST (UTC+3) in summer, and uses the Bulgarian Lev (BGN) as its currency. The official language is Bulgarian, and employment contracts must be written in Bulgarian.
Payroll runs monthly. Employer social contributions fall between 18.92% and 19.62% of gross salary, capped at approximately EUR 2,112 per month of insurable income. That cap matters: for higher-earning technical hires, maximum total social security per employee is approximately EUR 700 per month regardless of actual salary, which keeps your cost model clean.
Personal income tax is a flat 10%, one of the lowest rates in the EU. Combined employer and employee contributions run approximately 32.7% to 33.4% of gross salary. The standard working week is 8 hours per day and 40 hours per week. Bulgaria observes 15 public holidays annually. Overtime premiums are 150% on regular days, 175% on weekends, and 200% on national holidays. Length of service pay accrues at a minimum of 0.6% per year of service. Oyster surfaces all statutory minimums and contribution rates inside the platform so your offer letters start from a compliant baseline, not a guess.
What hiring in Bulgaria actually looks like
A real scenario for hiring your first Bulgarian employee
You have identified a senior software developer in Sofia. You want to make a compliant offer within two weeks.
Without an EOR, you are looking at local entity registration, a Bulgarian address, ongoing accounting obligations, and a timeline that runs weeks to months before you can legally employ anyone. You also need local legal review of the contract, payroll configuration in BGN, and someone who knows that length of service pay must be factored into the offer from day one.
With Oyster, the compliant Bulgarian employment contract is generated with length of service pay already calculated, Bulgarian payroll is configured, and the employee is onboarded. US-based and UK-based companies are the top employers of Bulgarian talent through Oyster, and the onboarding workflow handles both markets in a single process. The developer in Sofia can be active within 48 hours of a signed contract.
What an EOR is and how it works in Bulgaria
How an employer of record works in Bulgaria
An employer of record is a third-party company that becomes the legal employer of your Bulgarian hire on local employment records while you direct the day-to-day work.
In practice, this means the EOR handles Bulgarian payroll in BGN, files monthly contributions with Bulgarian authorities, generates employment contracts in Bulgarian, and administers statutory benefits including length of service pay and annual leave. You retain full operational control. The arrangement is fully legal in Bulgaria under the EU employment framework, and it is the fastest path to compliant employment without entity overhead.
Oyster holds its own legal entity in Bulgaria, so you are never relying on a third-party sub-vendor to employ your people. That distinction matters when a compliance question arises at 5pm on a Friday: there is a direct line to the entity that actually employs your team, not a chain of intermediaries.
EOR versus setting up a legal entity in Bulgaria
Entity setup in Bulgaria requires local registration, a Bulgarian address, ongoing accounting obligations, and a timeline that typically runs two to four weeks once your paperwork is in order. The fixed overhead of maintaining a local entity only makes financial sense at scale. That threshold is typically enough in-country headcount to justify recurring legal, accounting, and compliance costs.
An EOR lets you hire within days. For a first hire or a small team, the math is straightforward: EOR service fees versus entity setup and maintenance costs, with the EOR winning on both speed and total cost at low headcount. Bulgaria's regulatory environment adds additional complexity for foreign entities navigating local compliance, which is another reason the EOR path is the default choice for companies testing the market or building distributed teams incrementally.
Bulgaria labor laws your EOR handles for you
Employment contracts and probationary periods in Bulgaria
Bulgarian employment contracts must be written and issued in Bulgarian. The probationary period is six months. Post-employment non-compete agreements are explicitly invalid and unenforceable under Bulgarian law, which changes how you protect your business interests.
If IP protection matters to your organization (and for software teams, it almost always does), the strategy shifts to NDAs during employment and well-documented exit procedures rather than post-employment restrictions. Oyster's legal team reviews Bulgarian labour law updates and pushes contract and policy changes to your team automatically, so you are never the last to know when the rules change.
Statutory leave and length of service pay in Bulgaria
Unused annual leave can be carried over to the following calendar year. When leave is postponed or remains unused by year-end, the employer must ensure its use within the next calendar year, no later than 6 months after the original year. Unused paid annual leave expires two years after the year it was accrued, regardless of reasonSick leave is statutory. Both are standard EU-level protections that your EOR administers without you needing to track them manually.
Length of service pay is the benefit that catches most employers off guard. It accrues at a minimum of 0.6% of monthly salary per year of service and professional experience. It counts experience from prior employers in similar roles, not just tenure with your company. The most common practice is to include length of service pay in the total offer amount rather than treating it as a separate line item. Oyster factors this into compliant offer generation automatically, so the number your candidate sees is the number that holds up under Bulgarian law.
Severance and termination rules in Bulgaria
Bulgarian law allows employers to offer mutual termination with severance of at least four times the employee's last gross monthly salary if the worker accepts. Notice periods apply under the Labour Code, and the grounds for termination are codified. Getting termination wrong is one of the highest-risk moments in any employment relationship, and Bulgaria is no exception.
When termination processes get complex, you have a dedicated contact at Oyster, not a support ticket queue. That human support at offboarding is the difference between a clean separation and a compliance issue that surfaces months later. The statutory default notice period is 30 calendar days for employees on indefinite-term contracts, extendable up to three months by mutual agreement, with no notice required during the six-month probationary period.
Bulgaria payroll, tax, and social contributions
How Bulgarian payroll tax and employer contributions work
Bulgaria applies a flat 10% personal income tax rate on employment income, one of the lowest in the EU and a genuine advantage for competitive compensation design.
Employer social contributions run 18.92% to 19.62% of gross salary. Employee contributions run approximately 13.78%, bringing the combined total to roughly 32.7% to 33.4%. The insurable income cap of approximately EUR 2,112 per month means maximum total social security per employee is approximately EUR 700 per month regardless of actual salary. For higher-earning technical hires, this cap makes Bulgaria's total employment cost more predictable than markets without a ceiling.
The US-Bulgaria tax treaty, signed in February 2007, prevents double taxation for US-headquartered businesses employing Bulgarian talent. Oyster runs Bulgarian payroll in BGN, handles monthly filings with Bulgarian authorities, and gives your finance team a clear employer-cost breakdown with no surprise deductions.
The workforce in Bulgaria and why companies hire there
Skills, sectors, and salary context for Bulgarian hires
Bulgaria has a strong tech and engineering talent pool within the EU, with a growing software development and BPO sector. For US and UK companies, it offers EU-based talent at salary levels competitive with Western Europe. You avoid the entity complexity of larger markets.
Here is the honest context: Bulgaria has experienced population decline and emigration, and competition for top technical talent is real (something worth knowing before you assume the market is wide open). That means compliant, competitive offers matter more than ever. Length of service pay is not just a legal requirement; it is a retention mechanism that signals to candidates that you understand the local market. Getting compensation structure right from day one is how you build a Bulgarian team that stays. Oyster customers across 120+ countries access Bulgarian talent without entity overhead, supporting competitive offers that retain skilled professionals long-term.
How to choose the right EOR for Bulgaria
Four criteria that matter most when evaluating Bulgaria EOR providers
Not all EOR providers are built the same, and the differences matter most when something goes wrong.
First, consider in-house entity versus sub-vendor risk. Does the EOR hold its own legal entity in Bulgaria, or does it rely on a local partner? Sub-vendor arrangements add a layer of distance between you and the entity that actually employs your people. Second, GDPR and local data compliance: Bulgaria's EU membership makes GDPR compliance non-negotiable, and your EOR must demonstrate data handling standards that meet European requirements. Third, pricing transparency: does the provider publish flat pricing, and are there termination fees? Hidden fees and exit charges are common in this market. Fourth, dedicated human contact versus shared support: when a compliance question arises, you want a named contact, not a ticket number.
Compliance when you hire in Bulgaria
How Oyster keeps your Bulgaria hires fully compliant
Oyster's compliance model for Bulgaria starts with the in-house legal entity: no sub-vendors, no intermediaries. Legally reviewed employment contracts are issued in Bulgarian. Statutory benefit calculations, including length of service pay, are built into the platform. Ongoing monitoring of Bulgarian Labour Code changes means your team receives automatic updates rather than discovering gaps during an audit.
GDPR-compliant data handling is standard, not optional. If you are currently engaging Bulgarian talent as contractors, misclassification risk under EU employment law is real and worth addressing before it becomes a problem. Oyster is the only B Corp-certified EOR, which means compliance is not just a legal checkbox. It reflects how your people are treated.
EOR pricing for your Bulgaria hires
What transparent EOR pricing for Bulgaria looks like
Oyster publishes flat, per-employee pricing with no hidden fees and no termination charges. What you see is what you pay.
Compare that against the overhead of Bulgarian entity setup: ongoing local accounting, a registered address, and legal maintenance costs that accumulate regardless of headcount. For a single Bulgarian hire, entity setup rarely makes financial sense. For a small team, the math still favors an EOR.

How Oyster compares to other EOR providers for Bulgaria
Oyster versus Deel and Remote for Bulgaria hires
Bulgaria is a well-served EOR market, and several providers operate here. The differences come down to four criteria that matter most for compliance-conscious buyers.
On in-house entity ownership, Oyster holds its own legal entity in Bulgaria. Based on publicly available documentation from Deel and Remote, some providers use local sub-vendor arrangements rather than direct entity ownership. Buyers should verify this directly with each provider before committing. On dedicated support, Oyster provides a named contact model rather than shared support queues. On termination fees, Oyster charges none. On B Corp certification, Oyster is the only certified B Corp among the major EOR providers, which reflects a commitment to ethical employment practices that goes beyond legal minimums. The right provider for your Bulgarian team is the one that holds up on all four.
