Employers in Bulgaria add 18.92% to gross salary in mandatory social security and health insurance contributions, a combined rate applied on top of gross before income tax is withheld. Bulgaria adopted the euro on 1 January 2026, so all payroll calculations now run in EUR rather than the Bulgarian lev. Pricing a hire accurately requires understanding how the flat 10% income tax, the contribution caps, and the statutory benefit obligations interact within the 2026 payroll stack.
Bulgaria operates a flat income tax system for the 2026 tax year, meaning a single rate of 10% applies to annual gross income from the first euro earned, with no progressive bands above that. This places Bulgaria among the lowest personal income tax regimes in the European Union, and the rate has remained unchanged for nearly two decades. Income tax is collected through employer withholding at source and reported to the National Revenue Agency (Natsionalna agentsiya za prihodite, NAP), the authority responsible for administering personal income tax in Bulgaria.
For a mid-level professional in Sofia's IT outsourcing or fintech sector earning a gross monthly salary in the EUR 1,500 to EUR 2,500 range, the flat structure means there is no marginal rate cliff to model across the salary band. Every euro of annual gross is taxed at 10%, which simplifies both payroll software configuration and net-pay communications with candidates. The National Revenue Agency (NAP) requires employers to calculate and remit withheld tax on a monthly cycle aligned to each payroll period, with the annual gross figure reconciled at year-end through the employee's annual tax return or employer declaration.

Bulgarian employers contribute a combined 18.92% of gross salary in social charges above the gross. This figure is the sum of a 14.12% social security contribution and a 4.8% health insurance contribution, both applied to the employee's gross salary each month. From a buyer's perspective, 18.92% is the direct on-cost you pay above gross for every Bulgarian hire before factoring in any optional benefits or administrative costs.
A monthly contribution cap applies to both categories. Social security and health insurance contributions are calculated only on gross salary up to EUR 2,300 per month. Above that ceiling, no further employer contributions accrue on the excess, which means the effective percentage on-cost declines for senior roles priced above the cap. For context, EUR 2,300 per month sits above the statutory minimum wage of EUR 620.20 but well within the compensation range common in Sofia's software development and shared-services sectors.
Employers must model both scenarios when budgeting: roles below the cap where contributions scale linearly with gross salary, and roles above the cap where the social charge plateaus in absolute terms. The National Social Security Institute (NSSI), known in Bulgarian as Natsionalният osiguritelen institut, administers collection and benefit delivery on the social security side, while the National Health Insurance Fund (NHIF) covers the health contribution component.
| Contribution | Rate | Cap |
|---|---|---|
| Social security | 14.12% | 2,300 EUR/month |
| Health insurance | 4.8% | 2,300 EUR/month |
| Employer total | 18.92% |
Before income tax is applied to an employee's gross salary, Bulgarian employees contribute a combined 13.78% toward social security and health insurance. This breaks down into 10.58% for social security and 3.2% for health insurance, both deducted from gross salary each pay period. These deductions reduce the taxable base on which the National Revenue Agency (NAP) calculates the flat 10% income tax withholding, so the sequencing of deductions matters when modelling take-home pay.
One detail buyers frequently miss is the asymmetry between employer and employee health insurance rates: employers pay 4.8% while employees pay 3.2%, a 1.6 percentage-point gap that reflects a deliberate legislative split rather than an equal burden. The same EUR 2,300 monthly cap that applies to employer contributions also applies to employee contributions, so employees earning above that threshold see no further social or health deductions on the excess. For roles in Bulgaria's gaming and interactive entertainment sector, where senior engineers often command salaries that breach the cap, this ceiling materially affects both take-home pay projections and the employer's net contribution liability.
| Contribution | Rate | Cap |
|---|---|---|
| Social security | 10.58% | 2,300 EUR/month |
| Health insurance | 3.2% | 2,300 EUR/month |
| Employee total | 13.78% |
The Bulgarian Labour Code establishes a statutory minimum of 20 working days of annual paid leave under Article 155, with entitlement increasing based on years of service or role type. This floor applies to all full-time contracts regardless of sector, and employers cannot contractually substitute or waive it. Bulgaria also observes 14 public holidays per year, each representing an additional non-working day beyond the annual leave entitlement.
On sick leave, the Bulgarian structure splits the cost between employer and state. The employer funds the first three working days of any sick leave episode at 70% of the employee's average gross pay. From the fourth working day onward, the National Social Security Institute (NSSI) takes over, paying 80% of the employee's average insured income. This three-day employer liability is shorter than the equivalent obligation in several neighboring markets but must still be factored into workforce absence planning.
Maternity leave in Bulgaria totals 410 calendar days, covering 45 days pre-natal and the balance post-natal. Payments are made by the National Social Security Institute (NSSI) at 90% of average insured income, not by the employer directly, and the employee's position is legally protected throughout. A 13th-month salary payment is not required under Bulgarian law, so that cost does not enter mandatory benefit calculations.
| Entitlement | Value | Note |
|---|---|---|
| Annual paid leave | 20 working days minimum | per Bulgarian Labour Code Article 155; entitlement increases with service |
| Public holidays | 14 days | Labour Code art. 154: 10 fixed dates plus 4 movable Orthodox Easter days. The Council of Ministers list shows 15 entries because it adds 1 November, which is a day off for educational establishments only |
| Sick leave | first 3 working days at 70% of average gross pay (employer-paid); thereafter from NSSI at 80% of average insured income | |
| Maternity leave | 410 calendar days total (45 days pre-natal, balance post-natal) | paid through NSSI at 90% of average insured income, position protected |
The worked example below uses an assumed gross salary of EUR 2,500 per month, which is above the EUR 2,300 monthly contribution cap. This means the example applies both the employer social security rate of 14.12% and the employer health insurance rate of 4.8% only up to the cap, not to the full EUR 2,500 gross. The example includes all employer-side contributions and income tax withheld at source using the flat 10% rate after employee contribution deductions.
The example does not include sector-specific exemptions, individual deductions such as those for dependants, or any benefit-in-kind adjustments. Because Bulgaria does not mandate a 13th-month payment, no additional salary month is included. All numeric figures in the breakdown are calculated template-side from these inputs.

The 2026 State Social Insurance Budget Act set the maximum monthly insurable income at EUR 2,111.64 for 1 January to 31 July 2026 and EUR 2,300 from 1 August 2026. Contribution rates are unchanged; the draft budget pension increase was not adopted. The same ceiling applies to employment-contract and freelancer bases.
Bulgaria replaced the Bulgarian lev (BGN) with the euro (EUR) at the official conversion rate of 1.95583 BGN per EUR. All outstanding tax and other public liabilities were converted to EUR on 1 January 2026, and payroll calculations now run in euros.
The statutory minimum monthly salary rose to EUR 620.20 from the previous level of EUR 550.66 (BGN 1,077) in 2025. The increase coincides with the eurozone transition and applies to all full-time employment contracts.
Employers engaging staff in Bulgaria must register with the National Revenue Agency (NAP), the body responsible for income tax withholding, before processing their first payroll. Registration establishes the employer's obligation to withhold the flat 10% personal income tax and to file monthly payroll declarations. Social security and health insurance contributions are separately administered: the National Social Security Institute (NSSI) handles social fund registrations and benefit payments, while the National Health Insurance Fund (NHIF) administers the health contribution side.
Bulgaria's primary electronic compliance interface is the NAP's online portal, through which employers submit monthly payroll declarations, remit withheld income tax, and file social contribution data. The filing cadence is monthly, with declarations and payments due in the period immediately following each payroll run. Employers must also notify the National Revenue Agency of each concluded or amended employment contract within three days, under Article 62(3) of the Labour Code. Article 63 bars the employee from starting work until the employer has handed over the signed contract plus the NRA-certified copy of that notification. There is no separate per-hire registration with the NSSI: the NRA collects the contributions and transfers them onward.
From a practical standpoint, companies new to Bulgaria should also note that changes to payroll structure, such as a salary increase that moves an employee above or below the EUR 2,300 monthly contribution cap, must be reflected in the same month's declaration through the National Revenue Agency (NAP) portal. Discrepancies between declared gross salaries and contribution remittances are subject to automated reconciliation. Buyers using an employer of record or a local payroll provider should confirm that the provider maintains active credentials across both the NAP portal and the NSSI registration system.
Bulgarian employers contribute a combined 18.92% of gross salary, consisting of 14.12% for social security and 4.8% for health insurance. Both contributions are capped at a monthly gross of EUR 2,300, so no further employer charges accrue on salary above that ceiling.
The National Revenue Agency (NAP) applies a single 10% rate to all annual gross income, with no progressive bands. Employers withhold income tax monthly after deducting employee social security and health contributions from gross. The flat structure eliminates marginal-rate modelling across salary levels, which simplifies payroll configuration.
On 1 January 2026, Bulgaria replaced the Bulgarian lev with the euro at the official conversion rate of 1.95583 BGN per EUR. All payroll calculations, contribution caps including the EUR 2,300 monthly ceiling, and tax filings now run in euros. Legacy contracts or templates denominated in BGN required updating at transition.
Bulgarian employers fund the first three working days of any sick leave episode at 70% of the employee's average gross pay. From the fourth day onward, the National Social Security Institute (NSSI) pays 80% of average insured income. The employer's direct liability is therefore limited to the initial three-day period.
No. Bulgarian law does not mandate a 13th-month payment. Mandatory cost obligations are limited to gross salary, the 18.92% employer contribution stack, the 20 working-day minimum annual leave under Labour Code Article 155, 14 public holidays, and the three-day employer-paid sick leave exposure.
