Accounting for Digital Nomads and Foreign Entrepreneurs in Bulgaria (2026): Residency, Tax, VAT and Bookkeeping Explained

Accounting for digital nomads Bulgaria has become one of the most searched compliance topics of 2026, as remote workers, freelancers and online sellers increasingly base themselves in a country with a flat personal income tax and a growing reputation as a practical European hub. The stakes are real: misjudging the 183-day residency rule, missing a VAT registration trigger, or keeping incomplete books can turn an otherwise straightforward situation into a costly audit. This guide, written from an advisory perspective, explains Bulgarian tax residency, how personal taxation applies to remote and platform income, when VAT and OSS obligations arise for e-commerce, what bookkeeping records you must keep, and what services cost in 2026.

Throughout, we point to the authoritative Bulgarian and EU sources so you can verify every rule for your own circumstances.

Do you owe tax in Bulgaria? Residency and taxation for nomads

The first question almost every foreign entrepreneur asks is whether they become taxable in Bulgaria simply by living or working there. The answer depends on whether you are a Bulgarian tax resident, which is a different concept from immigration status or how long your visa lasts. Tax residency determines whether Bulgaria taxes your worldwide income or only income sourced inside the country. Understanding this distinction is the foundation of sound accounting for digital nomads Bulgaria, because it shapes everything from which returns you file to how your freelance invoices are treated.

Bulgarian tax residency is established through objective tests set out in the Personal Income Tax Act (Zakon za danatsite varhu dohodite na fizicheskite litsa), as published in the State Gazette. The tests most relevant to nomads include the 183-day physical-presence test and the “centre of vital interests” test. Either can make you a resident, and the centre-of-vital-interests test can apply even when you fall short of the day count. For anyone spending meaningful time in Bulgaria, both tests should be assessed together rather than relying on days alone. Note that Bulgarian law also treats individuals with a permanent address in Bulgaria as potentially resident, subject to the centre-of-vital-interests qualification, so confirm the full statutory criteria with the National Revenue Agency.

The 183-day test, how it works

Under the 183-day rule, an individual who is physically present in Bulgaria for more than 183 days in any 12-month period is generally treated as a Bulgarian tax resident, with residency attributed to the year in which the 183rd day falls. Days are counted on a presence basis, so part-days typically count, and short trips abroad do not automatically reset the clock. The practical effect is that a nomad who stays nine months while working remotely will usually cross the threshold and, if resident, becomes taxable on worldwide income.

Consider two scenarios. A freelancer who spends 150 days in Bulgaria and the rest of the year travelling across Asia is unlikely to meet the day test, but may still be caught by the centre-of-vital-interests test if their main economic ties are Bulgarian. Conversely, a remote worker who settles in Sofia for most of the year clearly exceeds 183 days and should plan for resident filing. Verify the current statutory wording through the National Revenue Agency and the State Gazette text of the Personal Income Tax Act before relying on any single figure.

Centre of vital interests, practical indicators

The centre-of-vital-interests test looks beyond the calendar to where your life is genuinely anchored. It is a facts-and-circumstances assessment, and no single factor is decisive. Bulgarian authorities weigh a combination of personal and economic connections to decide whether Bulgaria, rather than another state, is your real base.

• Family. Where your spouse, partner or dependent children habitually live.
• Property. Whether you own or permanently rent a home in Bulgaria that is available to you year-round.
• Economic interests. Where your main business, clients, bank accounts and income-generating activity are located.
• Habitual abode. The place where you spend your settled, everyday life rather than temporary stays.

Because this test can make you resident even below 183 days, it is central to accounting for digital nomads Bulgaria. A nomad who buys an apartment, moves their family and runs their online business from Sofia may be a Bulgarian resident after a few months, regardless of travel. Where another country also claims you, a double taxation treaty tie-breaker usually decides residency, confirm the position with the NRA and the relevant treaty.

Non-resident tax liabilities

If you are not a Bulgarian tax resident, Bulgaria generally taxes only your Bulgarian-sourced income. That typically includes employment carried out physically in Bulgaria, rental income from Bulgarian property, and fees for services performed within the country. Income you earn from foreign clients for work done while merely visiting is treated differently from income genuinely sourced in Bulgaria, so the source of each payment matters. Non-residents should document where work is performed and keep contracts and invoices that evidence source, as confirmed against NRA guidance.

How Bulgarian personal taxation applies to remote work, freelancing and platform income

Once you have settled your residency position, the next layer is how different income streams are taxed. Bulgaria distinguishes between employment income, self-employment or freelance income, and director fees, and each has its own treatment for tax and social security. Platform income, earnings from marketplaces, gig apps or content platforms, is usually treated as self-employment or business income rather than wages, which changes both the reporting mechanism and the social-contribution profile. Getting these categories right is what separates clean accounting for digital nomads Bulgaria from the kind of guesswork that triggers penalties.

Withholding and employer obligations

Where an individual is employed under a Bulgarian employment relationship, the employer is generally responsible for withholding income tax at source and remitting it, alongside social security contributions, to the authorities. This shifts much of the monthly compliance burden onto the employer. Foreign companies that hire someone physically working in Bulgaria should check whether they create withholding and registration obligations in the country, because employing a resident often brings payroll duties even without a local entity. Confirm current employer obligations through the National Revenue Agency and the National Social Security Institute.

Self-employed and service providers, registration and social security

Freelancers, consultants and platform sellers operating on their own account are usually responsible for their own registration, tax calculation and social contributions. That means registering the activity, obtaining the correct tax identification, and accounting for both income tax and mandatory social security on business income. Self-employed contributions are calculated on an insurable income base within statutory minimum and maximum limits rather than simply on profit, and the rules differ from those for employees, a point where many nomads underestimate their liability. The applicable contribution rates and the insurable-income ceiling are set annually; confirm the current figures with the NSSI and NRA.

Social security treatment is particularly important for remote workers who perform services while in Bulgaria, because contribution obligations can arise even where the client is abroad. The National Social Security Institute sets out registration and contribution rules for the self-employed. This article is advisory and does not substitute for tailored tax advice; before structuring your freelance activity, confirm your social security position with the NSSI and NRA, and check any applicable EU social security coordination rules or bilateral agreements between Bulgaria and your home country.

VAT and e-commerce: OSS, distance selling thresholds and registration triggers

For online sellers, VAT is frequently the single biggest compliance risk. The rules changed significantly across the EU in recent years, and marketplace sellers routinely misjudge where and when they must register. Whether you sell physical goods, digital products or services to consumers across the EU, you need to know three things: the EU distance-sales threshold, whether the One-Stop Shop (OSS) applies to you, and when a local Bulgarian VAT registration is nonetheless required. This is one of the densest areas in accounting for digital nomads Bulgaria, and the one where authoritative citation matters most.

Broadly, if you make cross-border business-to-consumer sales of goods or certain services to customers in other EU member states, those sales are subject to VAT in the customer’s country once your total cross-border B2C sales exceed the EU-wide threshold of EUR 10,000 in a calendar year. Below that threshold you may charge VAT at your own country’s rate; above it, VAT is due where the customer is located. The OSS exists precisely to let you report all of that through a single return rather than registering in every destination state.

Note that Bulgaria also operates a separate domestic VAT registration threshold for turnover generated in Bulgaria, verify the current domestic threshold and the EU distance-sales rules through the European Commission’s One-Stop Shop guidance and the National Revenue Agency.

One-Stop Shop (OSS) explained, who should use it and how

The OSS is an optional single electronic registration that lets a seller declare and pay VAT on cross-border B2C supplies across all EU member states through one periodic return filed in a single country. For a Bulgaria-based seller, this typically means registering for the Union scheme and submitting consolidated OSS returns rather than juggling multiple national registrations. The mechanism simplifies compliance for anyone selling to consumers in several EU countries.

In practice, using the OSS involves a few predictable steps:

1. Register for the relevant OSS scheme through the National Revenue Agency’s electronic services portal.
2. Apply the correct VAT rate of each customer’s member state to your qualifying B2C sales.
3. File the periodic OSS return declaring sales by member state and VAT rate, and pay a single consolidated amount.
4. Keep detailed records of each transaction, customer location, value and VAT applied, for the statutory retention period, so you can support the return if queried.

Filing frequency and record-keeping requirements for the Union OSS scheme are set out in the European Commission’s OSS guidance and administered locally by the National Revenue Agency. The Union scheme is generally reported on a quarterly cycle, but confirm the current filing calendar with the NRA. Because OSS covers specific categories of supply, always confirm that your particular products or services qualify before relying on it.

When to register in Bulgaria vs use OSS

OSS does not replace every Bulgarian VAT obligation. You may still need a domestic VAT registration in a number of situations, and the distinction trips up many sellers. The general principle is that OSS handles cross-border B2C supplies, while local registration handles domestic supplies and certain other activities.

• Local warehouse or stock in Bulgaria. Holding inventory in Bulgaria to fulfil orders typically points toward domestic VAT obligations.
• B2C domestic sales. Sales to Bulgarian consumers from within Bulgaria are domestic supplies, not distance sales covered by OSS.
• Distance sales to Bulgaria. A seller established elsewhere shipping to Bulgarian consumers may report those sales through OSS once over the threshold, rather than registering locally.
• Business-to-business supplies. B2B transactions follow different VAT rules and are generally outside OSS.

Because the interaction between domestic registration and OSS depends on where your stock sits and who your customers are, confirm your specific position with the National Revenue Agency. Clear VAT mapping is a defining feature of professional accounting for digital nomads Bulgaria who sell online.

VAT invoicing, e-commerce platforms and marketplaces

Invoicing discipline underpins every VAT position. Each qualifying sale needs a compliant invoice or record showing the VAT treatment, the customer’s location and the rate applied. Where you sell through a marketplace, the platform may in certain cases be treated as the “deemed supplier” and carry its own VAT reporting duties, but that does not automatically remove all of your obligations, and the detail depends on the arrangement. Review marketplace terms alongside NRA and European Commission guidance to confirm who accounts for VAT on each transaction.

Bookkeeping in Bulgaria: required records, retention and 2026 fee benchmarks

Good bookkeeping is where compliance either holds together or falls apart. Bulgarian rules, principally the Accountancy Act (Zakon za schetovodstvoto) and the tax legislation, require businesses to maintain orderly accounting records that support their tax and VAT positions, and these records must be available if the authorities review your affairs. For a non-resident running a Bulgarian entity, disciplined record-keeping is doubly important because cross-border structures attract closer scrutiny. This section sets out what to keep, for how long, and what you should expect to pay for help in 2026, the core operational side of bookkeeping Bulgaria for foreign entrepreneurs.

What records must you keep?

At a minimum, a Bulgarian business should maintain a complete and reconcilable set of primary documents and ledgers. These records are the evidence base for your tax returns, VAT filings and annual accounts, and they must be kept in an organised, retrievable form.

• Sales invoices. Every outgoing invoice, numbered and dated, with correct VAT treatment.
• Purchase invoices. Supplier invoices supporting deductible expenses and input VAT.
• Bank statements. Full statements for every business account, reconciled to the ledgers.
• Payroll records. Employment contracts, payslips and contribution records where you employ staff.
• VAT records. Purchase and sales VAT ledgers where you are VAT-registered, plus OSS transaction records if applicable.
• General and subsidiary ledgers. The accounting books that consolidate all transactions into your financial statements.

The precise form and content of mandatory records are governed by the Accountancy Act and Bulgarian tax legislation; confirm the current requirements through the National Revenue Agency and the Ministry of Finance before finalising your record-keeping system.

Retention periods and audit readiness

Accounting and tax records must be retained for statutory periods so they remain available for inspection. Retention durations vary by document type, payroll and social security records, for example, are generally kept for much longer than routine commercial documents, so you should not apply a single blanket period to everything. Check the exact retention durations for each category with the NRA and Ministry of Finance under the current Accountancy Act and Tax and Social Insurance Procedure Code.

Audit readiness is less about anticipating a specific inspection and more about keeping your books in a state where any query can be answered quickly. In practice this means reconciling bank accounts monthly, filing invoices consistently, documenting the source of foreign income, and retaining contracts that evidence where services were performed. For non-resident directors, maintaining clear records of cross-border transactions and intra-group arrangements is particularly valuable, because these are the areas examiners probe first.

Bookkeeping service levels and 2026 monthly fee benchmarks

Fees for bookkeeping in Bulgaria vary with transaction volume, VAT status, payroll, multi-currency activity and the level of advisory support you need. A low-volume freelancer pays far less than a multi-channel e-commerce seller with payroll and OSS returns. The table below sets out indicative 2026 market benchmarks in Bulgarian lev (BGN); these figures reflect general market pricing observed across the sector rather than any statutory tariff, and actual quotes depend on complexity. Always obtain a tailored quote.

As a rule of thumb, expect fees to rise with the number of monthly transactions, the presence of payroll, multi-currency bookkeeping, and any additional reporting such as foreign bank disclosures. When comparing quotes, confirm exactly which filings and reconciliations are included, because a low headline price that excludes VAT returns or payroll can cost more once add-ons are counted.

Company formation and required accounting records, practical checklist

Many foreign entrepreneurs eventually decide to incorporate rather than operate as individuals, usually for limited liability, credibility with clients, or to support hiring. A Bulgarian limited liability company (an OOD or, for a single owner, an EOOD) is the most common vehicle. Incorporation is straightforward in principle, but the accounting obligations begin the moment the company exists, so setting up your books correctly from day one avoids painful corrections later. This is where accounting for digital nomads Bulgaria moves from personal compliance to entity compliance.

Basic steps to register a Bulgarian company

At a high level, forming a Bulgarian limited company involves preparing the constitutional documents, arranging the required share capital (the statutory minimum share capital for an OOD/EOOD is a nominal amount, confirm the current figure with the Registry Agency), and registering the entity with the Commercial Register maintained by the Registry Agency. Once registered, the company receives its unified identification code (EIK) and can open a business bank account and commence trading. The exact documentation, capital and procedural requirements are set by the Registry Agency, so confirm the current rules there before filing. Our step-by-step company formation and accounting guide walks through the process in detail.

Accounting set-up checklist for a new company

Once the company is registered, put a proper accounting framework in place immediately. A clean setup makes every subsequent filing easier and reduces the risk of errors in your first returns.

• Chart of accounts. Establish a chart of accounts suited to your business model and reporting needs.
• Opening capital entries. Record the share capital and any founder contributions correctly from the outset.
• VAT assessment. Determine whether and when VAT or OSS registration is required, and prepare the first VAT return cycle accordingly.
• Payroll setup. If you will employ staff, register as an employer and configure payroll and social security reporting with the NSSI and NRA.
• Fiscal device considerations. If you operate retail or cash sales, check whether fiscal cash register obligations apply.
• Banking and reconciliation. Open the business account and set a monthly reconciliation routine from month one.

Verify employer and VAT registration requirements with the NRA, NSSI and Registry Agency as part of your setup, and keep the registration confirmations on file.

Practical compliance calendar and checklist for digital nomads and foreign entrepreneurs

Compliance in Bulgaria runs on a rhythm of monthly, periodic and annual obligations. The specific due dates depend on your VAT status, whether you run payroll, and your corporate income tax cycle, and they can change with legislative amendments, so always confirm current deadlines with the National Revenue Agency rather than relying on memory. A simple calendar keeps you ahead of each filing window and prevents late-filing penalties, which are entirely avoidable with basic planning.

• Monthly. VAT returns and payments where VAT-registered; payroll processing and social security filings where you employ staff; bank reconciliation and bookkeeping.
• Periodic. OSS returns on their set reporting cycle for qualifying cross-border B2C sellers.
• Annual. Preparation and filing of annual financial statements with the Commercial Register, and the relevant personal income or corporate tax returns, within the statutory deadlines.

Treat this as a framework and populate it with the exact dates that apply to your registrations, verified against NRA guidance. If you would like a one-page compliance checklist tailored to your situation, an advisor can prepare one covering your filings and deadlines in a single view.

When to engage an ACCA-qualified advisor for accounting for digital nomads Bulgaria

Not every situation needs ongoing professional support, but several clearly do. If any of the following apply, the cost of advice is almost always lower than the cost of getting it wrong. Professional input is especially valuable at the points where residency, VAT and social security intersect, precisely the areas that define accounting for digital nomads Bulgaria.

• Cross-border income. You earn from multiple countries and need to apply treaty rules correctly.
• Payroll. You employ staff in Bulgaria and must manage withholding and social contributions.
• OSS complexity. You sell to consumers across several EU states and need reliable VAT reporting.
• Audit or scrutiny risk. Your structure involves non-resident directors or intra-group transactions.

An ACCA-qualified accounting advisor can assess your residency position, map your VAT obligations, set up compliant bookkeeping and keep you aligned with Bulgarian and EU requirements, on an advisory basis rather than as legal representation. You can reach out through the profile of Tsvete Obreshkova, ACCA accounting advisor in Bulgaria.

Conclusion and next steps

Accounting for digital nomads Bulgaria is manageable once you approach it in the right order: confirm your residency position using both the 183-day test and the centre-of-vital-interests test, classify each income stream correctly for tax and social security, map your VAT and OSS obligations against your sales pattern, and keep clean, retrievable books from day one. Verify every rule and deadline against the National Revenue Agency, the State Gazette, the Ministry of Finance, the NSSI and the European Commission’s OSS guidance, because thresholds and dates can change. The practical next steps are simple, check your days, track your turnover, build your compliance calendar, and engage an ACCA-qualified accounting advisor to set up and maintain your bookkeeping.
