RemoteMore is a remote developer hiring and Employer of Record platform that has screened more than 50,000 engineers across Europe and Latin America since 2019. Salary figures below are from RemoteMore placement data, September 2026. Tax and contribution rates are from PwC Worldwide Tax Summaries and the Bulgarian State Social Security Budget Act for 2026.
A senior software engineer in Bulgaria costs a US company roughly $85,000–$100,000 a year all-in, including employer contributions and an Employer of Record fee. The same seat in the US runs $165,000 or more. The reason the gap holds even at senior level: Bulgarian social contributions are capped at about €2,300 of monthly salary, so the employer’s cost above that is zero. Bulgaria adopted the euro on 1 January 2026, applies a flat 10% income tax, and has roughly 105,000–125,000 ICT specialists, most of them in Sofia. It fits teams hiring 1–10 engineers. It does not fit teams that need 50.
Here is the full breakdown.
How much does a software engineer cost in Bulgaria in 2026?
Gross salary ranges from RemoteMore placements, Sofia market, September 2026. All-in cost adds employer social and health contributions (approximately 19% of gross, capped) and a typical EOR fee of $400–600 per month.
| Level | Gross salary (USD/yr) | Employer contributions | EOR fee | All-in cost (USD/yr) |
|---|---|---|---|---|
| Junior (0–2 yrs) | $25,000–$38,000 | ~$5,000–$6,000 | ~$6,000 | $36,000–$50,000 |
| Mid (3–5 yrs) | $40,000–$60,000 | ~$6,000 (capped) | ~$6,000 | $52,000–$72,000 |
| Senior (6+ yrs) | $62,000–$95,000 | ~$6,000 (capped) | ~$6,000 | $74,000–$107,000 |
| Senior AI/ML | $70,000–$110,000 | ~$6,000 (capped) | ~$6,000 | $82,000–$122,000 |
For comparison, a senior engineer in the US at $130,000 gross costs about $165,000 with payroll taxes and benefits. In Poland, a $70,000 gross salary lands around $90,000 all-in because Polish contributions are not capped in the same way.
Sofia salaries run 20–30% above Plovdiv, Varna, and Burgas. Engineers working for international remote employers are often paid above the local ranges, so treat the figures above as what it takes to hire, not the local average.
Why are employer costs in Bulgaria capped?
Bulgarian employers pay social security and health insurance at roughly 18.9%–19.6% of gross salary, depending on the industry accident-fund rate. Software companies sit at the low end.
Those contributions are only calculated on salary up to the maximum insurable income. From 1 August 2026 that ceiling is €2,300 per month (it was €2,111.64 for the first seven months of the year). Above €2,300 a month — about €27,600 a year — no contributions are due from either side. Only the 10% flat income tax applies to the excess.
The practical effect: employer contributions max out at roughly €5,200 a year, about $6,000. A $40,000 engineer and a $95,000 engineer cost the employer the same in contributions. Bulgaria gets cheaper, in percentage terms, the more senior the hire.
This is the single feature that separates Bulgaria from most of the EU. Germany, France, and Belgium apply contributions up to very high ceilings, so the on-cost scales with the salary. Bulgaria’s does not.
What does the engineer pay in tax?
- Personal income tax: flat 10% on all employment income, no bands, no allowance. The lowest flat rate in the EU.
- Employee social and health contributions: 13.78% of gross, also capped at the €2,300 monthly ceiling.
A senior engineer at €6,500 gross per month keeps roughly €5,500 net. That matters for offers: a Bulgarian engineer compares your offer to net pay at home, and the 10% rate means a modest gross number buys a strong net one.
Corporate tax is also a flat 10%, and the combined corporate-plus-dividend rate is 15%. This is relevant if you ever open an entity, covered below.
How big is Bulgaria’s engineering talent pool?
- Roughly 105,000–126,000 ICT specialists depending on the definition used (Eurostat, BASSCOM, and industry surveys triangulate to this range). About 70,000 of them are in software and IT services.
- Around 6,100 software companies, with 87% of software-sector revenue coming from exports. Bulgarian engineers are used to working for foreign clients.
- Sofia holds about 88% of the country’s ICT value-added and the large majority of engineering jobs.
- ICT specialists are 4.6% of total employment, just under the EU average of 5%.
- Strong university pipeline in mathematics and computer science; SAP, Microsoft, VMware, and Oracle all run engineering centres in Sofia.
The constraint is depth. Bulgaria’s tech workforce is about a quarter the size of Poland’s 500,000+. It is deep enough to fill a squad of senior engineers within weeks. It is not deep enough to hire 50 people in one stack without moving the market.
Contractor, EOR, or entity: how should a foreign company employ a Bulgarian engineer?
Three legal structures. Most companies pick late, after the offer, and that is where the risk comes from.
| Independent contractor | Employer of Record (EOR) | Bulgarian entity (EOOD) | |
|---|---|---|---|
| Time to first hire | Days | Days | 4–8 weeks plus bank account |
| Ongoing cost | Invoice only | $400–600 per employee per month | Registration, local accountant, payroll filings, statutory reports; typically €10,000–20,000+ per year before salaries |
| Misclassification risk | High if the person works your hours, your tools, your manager, one client | None; the EOR is the legal employer | None |
| IP ownership | Depends entirely on the contract; Bulgarian law does not default IP to the client | Assigned to you through the employment contract | Assigned to you through the employment contract |
| Benefits, leave, social security | Contractor’s own problem; senior candidates often decline these arrangements | Full local employment | Full local employment |
| Best for | Genuinely independent, project-scoped work | 1–10 people, or any hire where you are not yet committed to the country long-term | 10+ people in Bulgaria with a multi-year plan |
Where the contractor route goes wrong: Bulgarian authorities, like most of the EU, look at the real relationship rather than the contract title. An engineer who works full-time on your product, reports to your manager, uses your systems, and has no other clients is an employee with the wrong paperwork. Exposure is back contributions, penalties, and unclear IP. It rarely gets caught in year one. It gets caught in year three, during due diligence.
The crossover between EOR and entity sits higher than most founders expect. At $500 a month per employee, an EOR for 8 people is $48,000 a year. An entity with a local accountant, director, and compliance runs a similar figure before you have paid anyone. Below 8–12 employees in Bulgaria, the EOR is usually cheaper and always faster. Above that, open the entity.
What do you need to know about Bulgarian employment law?
Bulgaria’s Labour Code is aligned with EU directives. The items that surprise US employers:
- Written contract required before the start date, registered with the National Revenue Agency. No handshake starts.
- Probation up to six months, during which either side can terminate without notice.
- Paid annual leave: minimum 20 working days, plus public holidays.
- Notice periods for indefinite contracts: 30 days minimum, up to three months by agreement, symmetrical for both sides.
- Termination must fit one of the grounds listed in the Labour Code. At-will does not exist. Redundancy carries at least one month’s salary in severance.
- Payroll runs at least monthly, with tax and contributions filed by the 25th of the following month.
- Working time: 40 hours a week standard; overtime is restricted and must be paid at premium rates.
- Remote work is recognised in the Labour Code, with employer obligations around equipment and health and safety that an EOR handles.
None of this is onerous by EU standards. All of it is unfamiliar to a US company doing it alone, which is the case for using an EOR for the first hires.
What changed in Bulgaria in 2026?
- Euro adoption on 1 January 2026. Salaries, contracts, and payroll are now in euro at the fixed conversion rate of 1.95583 leva. No FX risk on payroll for eurozone employers; a single currency conversion for US ones.
- Contribution ceiling raised to €2,300 a month from 1 August 2026, up from €2,111.64. The employer’s maximum annual contribution rose by about €430.
- Minimum wage set at €620.20 a month. Irrelevant for engineering salaries, but it fixes the minimum insurable income for any hire.
- Contribution rates unchanged. A proposed 2-point pension increase was not enacted in the final 2026 budget, adopted in July 2026.
- Schengen membership since 2025 has removed border friction for travel to and from the rest of the EU.
Where Bulgaria doesn’t fit
- Scale: not a market for 50-engineer hiring plans. Use Poland or a multi-country strategy.
- US Pacific time: Sofia is EET, ten hours ahead of San Francisco. Overlap with the US East Coast is workable (morning in New York is afternoon in Sofia); overlap with the West Coast is two to three hours at most.
- Local-only stacks: strongest in Java, .NET, JavaScript/TypeScript, Python, and embedded. Thinner in niche or very new stacks.
- Salary expectations rising: Bulgarian engineering salaries have grown faster than most of the EU since 2021. The cost advantage is real but narrowing; budget with a 10–15% increase over what you would have paid two years ago.
