Payroll Service in Bulgaria

Outsourced payroll services in Bulgaria cover the calculation, withholding, and remittance of an employee’s income tax and social security contributions on the employer’s behalf. Under the full-employment model, a provider specializing in outsourced payroll in Bulgaria manages both employer-side and employee-side statutory obligations for every payroll cycle, so the client company never handles local tax filings directly.

Employee’s share:

• Personal income tax: 10%
• Social Security contributions:
  • Mandatory state pension fund: 6.58%
  • Additional mandatory pension insurance: 2.2%
  • General illness and maternity fund: 1.4%
  • Unemployment fund: 0.4%
  • Health insurance fund: 3.2%

The maximum monthly insurance base is currently capped at BGN 4,130 (~USD 2,500). Bulgaria’s 2026 Public Social Insurance Budget Act, which has passed its first parliamentary reading, is set to raise this threshold to EUR 2,300 (~USD 2,700), effective August 1, 2026, pending final adoption.

For a tech specialist with a monthly gross remuneration of $5,000, the effective tax rate – combining PIT and SSC – comes to approximately 16.2% of gross income.

Employer’s share:

• Social Security contributions:
  • Mandatory state pension fund: 8.22%
  • Additional mandatory pension insurance: 2.8%
  • General illness and maternity fund: 2.1%
  • Unemployment fund: 0.6%
  • Accident at work and occupational disease fund: 0.4%–1.1% (depending on economic activity; the rate for the administration and services sector is 0.5%)
  • Health insurance fund: 4.8%

The maximum monthly insurance base is currently capped at BGN 4,130 (~USD 2,500). Bulgaria’s 2026 Public Social Insurance Budget Act, which has passed its first parliamentary reading, is set to raise this threshold to EUR 2,300 (~USD 2,700), effective August 1, 2026, pending final adoption.

For an employee receiving a monthly remuneration of $5,000, the employer contributes an additional approximately 9.5% for SSC on top of the gross salary.

Under the B2B model, the contractor – not the employer – is responsible for calculating, withholding, and remitting their own personal income tax and social security contributions. The company generally isn’t required to cover these taxes directly, though understanding them matters for comparing the true cost of a B2B engagement against full employment.

According to Alcor’s legal team, Bulgaria taxes B2B contractors differently depending on registration status: freelancers pay a flat 10% personal income tax, while sole traders pay 15%. Social security contributions are the same across both categories.

Social Security contributions include:

• Pension Fund Contribution: 14.8%
• Universal Pension Fund: 5%
• Health Insurance: 8%

For an IT specialist with a monthly remuneration of $5,000, the effective tax rate – combining PIT and SSC – comes to approximately 21.4% for a freelancer and 25.2% for a sole trader, based on their gross income.

Local payroll payments in Bulgaria are shaped by statutory entitlements around paid leave, overtime, and sick pay that every employer – or PEO/EOR provider – must account for.

Employees are entitled to at least 20 working days of paid vacation per year. Overtime is generally prohibited in Bulgaria and permitted only in exceptional cases, subject to the following limits: up to 150 hours/year, 30 hours/month, 6 hours/week, and 3 hours/day for no more than two consecutive working days. It is paid at 150% of the regular rate on business days or under summarized working time, 175% on weekends, and 200% on public holidays.

For paid sick leave, employers cover 70% of the employee’s salary for the first two days. From the third day onward, social insurance covers 80%–90% of the employee’s salary for the full duration of the leave, until the employee recovers or their disability status is determined. For fixed-term and management contracts, sick-leave compensation is limited to 30 days after contract termination. This limitation does not apply to standard indefinite employment contracts.

Bulgaria offers a 25% “super deduction” on qualifying R&D operating expenses, according to Deloitte, and a matching 25% uplift in the acquisition cost of R&D-related capital expenditure, both retroactive to January 1, 2026, as reported by Bloomberg Tax. Companies can also draw on EU Horizon Europe grants and Bulgaria’s National Recovery and Resilience Plan for additional funding for R&D and digital transformation, according to the European Commission.

As a eurozone member since January 1, 2026, Bulgaria also removes currency-conversion exposure on EUR-denominated cross-border payroll and R&D spend – one less operational variable for companies scaling an R&D function there.

Payroll outsourcing services vendors in Bulgaria cover the full monthly payroll cycle – from tax calculation to statutory filing – handled by a local provider on the client’s behalf. Here are the key day-to-day tasks a payroll company in Bulgaria takes on: 

• Payroll tax planning, calculation, and consultation – covering PIT, SSC, and health insurance contributions
• Preparation and distribution of payslips and payroll statements for each pay period
• Preparation and submission of payroll returns to the NRA (National Revenue Agency) and NSSI (National Social Security Institute) 
• Statutory payroll reporting, including annual filings and audit-ready documentation
• Employee benefits administration – including meal vouchers, supplemental private health insurance, and pension contributions
• Processing monthly salary payments for tech teams and engineers

Qualification & experience

Choose a Bulgarian payroll services vendor with experienced payroll and legal advisors who specialize in the tech industry. Also, check their case studies, client reviews, and testimonials to confirm a track record of compliance accuracy and reliable delivery.

Pricing structure 

Consider a payroll outsourcing provider in Bulgaria with predictable pricing and detailed invoices to avoid hidden fees and, therefore, eliminate the risk of overpayment. 

Technology & security

Check whether a payroll outsourcing company in Bulgaria uses modern, reliable payroll processing software capable of handling your payroll requirements. Additionally, ensure that a payroll vendor implements data security protocols and encryption standards and complies with data privacy regulations to safeguard employee information.

Guarantees

Look for a payroll outsourcing solutions company that compensates for mistakes or missed deadlines. Clear turnaround timeframes and full pricing transparency are additional green flags worth confirming before you commit to an outsourced payroll service in Bulgaria.

Checklist for evaluating a payroll company in Bulgaria

Before committing to a payroll service company in Bulgaria, check for:

1. Proven experience serving tech companies specifically, not just general payroll clients
2. Verifiable case studies, client reviews, and references you can actually contact
3. Transparent, itemized pricing with no hidden fees or surprise charges
4. Modern payroll software suited to your team’s size and complexity
5. Documented data security practices and GDPR compliance
6. Written SLAs covering turnaround times and error-correction guarantees
7. A single point of contact for payroll and compliance questions

Payroll pricing in Bulgaria typically follows one of two structures: a flat per-employee fee or a base platform fee plus a smaller per-employee charge. Costs also vary depending on whether you need standalone payroll processing or full EOR/COR services that include compliance and benefits administration.

For small to mid-sized teams, outsourced payroll processing typically runs $50–$200 per employee per month, depending on service level and the number of countries involved. Some providers use a base fee model ($20–$100/month) plus a per-employee charge of $6–$25, with additional charges layered on for multi-country filings, year-end processing, or garnishment handling.

Common hidden fees to watch for:

• Setup or onboarding fees charged before the first payroll run
• Year-end tax filing surcharges are billed separately from the monthly service
• FX conversion fees on cross-border payments
• Mid-cycle changes – new hires, terminations, salary adjustments – are billed as extra transactions
• Contract termination or offboarding fees
• Benefits administration that is priced as an add-on rather than included in the base fee

Payrolling is cost-effective and saves significant administrative time – but only if you already have a legal entity in Bulgaria and simply need help running payroll against it. That’s a different scope from EOR/COR services, where the provider also absorbs compliance risk and typically prices as a single flat monthly fee per employee rather than a base-plus-per-transaction stack. Providers like Alcor structure this as one predictable fee with no separate setup deposits or FX charges layered on top.

Saves costs and time

Managing payroll internally means your accountants must calculate employees’ compensation for both in-house and outsourced development teams – and extra workload means additional hiring, staff training, and payroll experts who still need to learn Bulgaria’s labor laws, statutory regulations, and tax system from scratch. Outsourcing to payroll advisors reduces costs for new team members and frees your internal team to focus on core corporate financial priorities instead.

Mitigates compliance risk

Working with a Bulgarian payroll company shields your company from legal issues and fines, since local payroll consulting professionals know the ins and outs of local tax law, wage regulations, terminations, and compliance requirements – and stay current as those rules change, as Bulgaria’s did with its 2026 R&D tax incentives and euro adoption.

Keeps employee data safe

A payroll service in Bulgaria protects sensitive employee information – social security numbers, salaries, bank details – through cloud-based servers, data centers, and cybersecurity software that guard against embezzlement, identity theft, and other risks. This matters most for tech leaders who are otherwise hesitant to hand over payroll data to an outside provider.

Enables scalability

Outsourced payroll support lets tech companies handle fluctuations in headcount, benefit plans, and tax requirements without adding internal resources or infrastructure. This becomes essential once a company starts expanding its development team abroad and payroll needs grow more complex.

In Bulgaria, Alcor operates under a Contractor of Record (COR) model, managing B2B contractor agreements and payment records on the client’s behalf while the client retains full control over roles, team structure, and day-to-day engineering work. Engineers are engaged as independent contractors – sole traders under Bulgarian law – giving clients a compliant path to build a team without the time and cost of setting up their own local entity.

Clients set the agreed remuneration and bonuses; Alcor handles payroll processing for the contractor payment and takes care of the transaction to pay contractors directly each cycle. Bulgaria’s B2B structure means contractors register as sole traders and manage their own payroll taxes – PIT and SSC – which keeps the engagement lean and fast to set up compared to Alcor’s EOR markets.

In practice, these contractors function as full members of the client’s team, fully integrated into its organization. Clients can insource them into their own entity at any time, with no additional transfer fees.

Alcor’s COR model goes further than a standalone payment processor in Bulgaria. Alcor’s local experts manage contractor data, contract compliance, and payment administration within a single integrated payroll management system, backed by deep regional expertise. Because payments run inside a Contractor of Record framework, contractor agreements, IP and confidentiality clauses, and payment cutoffs stay aligned under a single model.

As a result, clients get corporate payroll services in Bulgaria that already sit inside a ready-to-scale COR structure, so expanding a tech team across Eastern Europe or Latin America becomes a change in headcount, not a change in legal setup.

Companies with an existing Bulgarian entity 

This is the core fit for standalone payroll services – the legal infrastructure is already built, and the company simply needs the monthly payroll cycle handled without hiring a dedicated in-house specialist.

Multi-market payroll operations

Companies already operating across several markets – Poland, Romania, and Bulgaria, for example – benefit from a single provider handling payroll consistently across all locations rather than managing a patchwork of local bookkeepers.

Companies without in-house expertise 

Bulgaria’s rules have shifted meaningfully in the past year – euro adoption, the new R&D “super deduction,” and insurance-based thresholds tied to the 2026 budget – and a company without a dedicated local specialist carries real compliance exposure it may not be aware of.

But note: Standalone payroll services only cover part of the picture, though. If you’re weighing whether to skip the entity altogether, or you’re already stretched thin coordinating separate vendors for recruitment, compliance, payroll, and HR – there’s a smarter way in. For tech companies looking to expand into the Bulgarian market, a software R&D center is the more comprehensive path worth exploring.

A payroll outsourcing company handles the transactional side of employment. Alcor goes further, covering:

• Payroll tax planning, calculation, and consultation
• Preparation and submission of statutory filings to local authorities
• Employee and contractor benefits administration
• Payslip and payment processing
• Ongoing compliance monitoring as local regulations change

But payroll is only one piece of what Alcor delivers. Alcor’s software R&D center solution combines all three core functions a growing engineering team actually needs – whether you’re a startup, a scale-up, or a mature tech enterprise: in-house tech recruitment, compliant Employer of Record and Contractor of Record services, and full operational support. One provider, one point of contact, no vendor layer.

Alcor is a one-stop-shop solution for Western tech product companies building software engineering teams, combining tech recruitment, Contractor of Record/Employer of Record services in Eastern Europe and Latin America, and full back-office operational support under a single software R&D center. No entity required, no vendor sprawl.

Companies like Ledger, Dotmatics, and ThredUP have all built and scaled engineering teams this way – from first hire to fully operational R&D center. Tonic Health, a US-based patient data platform, is a good example of what that looks like end-to-end.

Tonic Health came to Alcor with a clear goal: to launch a fully operational software R&D center in Eastern Europe. They’d tried to do it independently and hit a wall — job offer rejections, a weak employer brand in the local market, and no clear path to hitting their hiring targets.

Alcor addressed all three from day one:

• Silicon Valley-grade recruitment: Tapped into Alcor’s base of 325,000+ vetted engineers and hired 15 top-tier PHP engineers, DevOps, Frontend, Security Engineers, and QA Leads – all from the top 10% of local talent, with zero offer rejections and an average tenure of 2.5 years.
• EOR for tech: Alcor took admin and legal complexities off Tonic’s shoulders, including FTE or B2B employment, and covered full payroll, benefits, tax management, and legal compliance for every hire – significantly reducing Tonic’s legal exposure in a market where they had no prior presence. A dedicated Customer Operations Manager gave Tonic a single point of contact for the entire employment relationship, rather than juggling multiple internal functions.
• Full operational support: Built Tonic’s employer brand in the Eastern European market from scratch, negotiated office leasing, provided equipment, and set up back-office operations – 100% of back-office services handled from day one. Alcor also manages stock option administration, rounding out a complete back-office partnership for tech companies that need more than just employment infrastructure.

The result: a fully established R&D center in 3 months – no upfront costs, no buy-out fees, no entity required, and engineers who integrated seamlessly into Tonic’s culture as a true internal team from day one.
