Can I Start a Side Business While Employed in Serbia?

Moving to Serbia often sparks an entrepreneurial spirit, especially when you start to get a feel for the local economy and see opportunities around you. Many of us expats arrive with skills, a strong work ethic, and a desire to build something of our own, even if we’re already settled into a full-time job. The idea of a side business is appealing, offering extra income, creative outlet, or a stepping stone to something bigger. But navigating the Serbian legal and tax system for a side hustle while employed can feel like trying to solve a Rubik's Cube blindfolded. This guide will meticulously break down what you need to know to legally and successfully launch a side business without jeopardizing your main employment.

Understanding the Legal Landscape for Side Hustles in Serbia

It's tempting to just start selling handmade goods online or offering consultancy services without a second thought. But trust me, Serbia's administrative system has a way of catching up to you, and it's far better to be prepared than to deal with fines or, worse, complications with your primary employer.

The Basics: What Does Serbian Law Say?

Generally speaking, Serbian law doesn't explicitly prohibit you from having multiple sources of income or running a side business while being employed. This isn't like some countries where holding two jobs or being self-employed simultaneously is heavily restricted or requires special permissions from authorities beyond your employer. However, the critical caveat lies in how you conduct that side business and who your primary employer is.

The main concern for the Serbian state, as with most governments, is that you are properly contributing to the tax system and social funds based on all your earnings. Beyond that, the biggest hurdles you'll face will likely come from your employment contract or the nature of your side business. The crucial aspect is to ensure that your side hustle doesn't create a conflict of interest or directly compete with your main employer. Imagine working for a software development company during the day and then offering independent software development services to their direct competitors at night – that's a clear no-go and could lead to serious legal issues and termination of your employment.

Employer Contracts and Clauses to Watch Out For

Before you even think about registering anything, the first and most critical step is to pore over your existing employment contract. Seriously, get a Serbian friend or a lawyer to help you if you’re not comfortable with the legal jargon. Many expat contracts, especially with international companies or those in sensitive sectors like IT or finance, will contain clauses specifically addressing outside employment or business activities.

Look out for:

Non-compete clauses: These are common and usually state that you cannot engage in business activities that directly compete with your employer, either during your employment or for a specified period after. The scope (geographical, industry, duration) can vary wildly.
Confidentiality and Intellectual Property (IP) clauses: Many contracts will assert that any work you create, ideas you develop, or client relationships you cultivate during your employment or using company resources belong to the company. If your side business involves similar creative work or proprietary information, this can be a huge issue. Make sure your side hustle doesn't even come close to infringing on your current employer's intellectual property.
Notification requirements: Some employers, particularly larger ones, may require you to inform them of any secondary employment or business activities, even if they don't directly compete. This is often for transparency and to assess potential conflicts. Ignoring this could be a breach of contract.
Exclusivity clauses: While less common for general employment, some high-level or specialized roles might have clauses requiring you to dedicate 100% of your professional time and effort exclusively to the employer.

It’s always a good idea to have an open conversation with your employer, especially if your side business is clearly unrelated and won't impact your performance. Transparency can often prevent future headaches.

Tax and Contribution Implications: Early Considerations

One of the biggest eye-openers for expats looking into side income in Serbia is the tax system. It’s not just about paying a flat 10% income tax; there are social and health contributions too, which can significantly impact your net earnings. Many expats consult with a service like Taxes for Expats early on to understand these nuances. If you start earning income from a side business, you become responsible for declaring it and paying the associated taxes and contributions. This isn't something your primary employer will handle for your side gig, so it's entirely on you.

The crucial part is understanding that your side business income isn't simply added to your existing salary and taxed. Depending on the legal structure you choose for your side business, it will be treated as a separate entity for tax purposes. This means new obligations, new deadlines, and new calculations. Ignoring these can lead to penalties and a very unwelcome visit from the Poreska Uprava (Tax Administration).

Navigating the Most Common Legal Structures for Side Businesses

So, you've checked your employment contract, identified no major red flags, and you're ready to get serious. What's the best way to legitimize your side hustle in Serbia? The choices can seem daunting, but for most side businesses, one option stands out.

The 'Pausal' Entrepreneur (Preduzetnik Paušalac)

This is by far the most popular and often recommended option for expats running small, service-based side businesses or freelance gigs in Serbia. The "Pausal" regime, as it’s known, is a simplified tax system for small entrepreneurs. Instead of tracking every single expense and income, the state calculates a fixed monthly tax and contribution amount based on your declared activity, location, and a few other factors. This lump-sum payment simplifies everything immensely.

What it is: A Pausal entrepreneur is a registered individual business owner who pays a fixed, predetermined tax and contribution amount each month, regardless of their actual monthly income (up to a certain threshold). This eliminates the need for complex bookkeeping.

Who it's for: This is ideal for freelancers, consultants, online teachers (like those using platforms such as iTalki), designers, programmers, translators, and anyone offering services or selling products with relatively low overhead and an unpredictable income stream. If your side business is selling your knitted scarfs online, teaching English, or offering marketing advice, this is likely your best bet.

Why it's attractive:

Simplicity: Minimal paperwork, no need for an accountant for daily operations, and easy tax calculation. You just pay your monthly bill.
Predictability: You know exactly what your tax burden will be each month, which helps with budgeting.
Lower costs initially: For many, especially those starting out, the fixed costs can be lower than traditional bookkeeping.
Separate legal entity: It allows you to operate legally, issue invoices, and build your brand without mixing it with your personal finances (though it's still linked to your personal ID number).

Limitations:

Income cap: There's an annual income limit (around 6 million RSD, though this can change) for qualifying as a Pausal entrepreneur. If your side business explodes, you'll need to switch to a different regime.
Limited expense deductions: Since your tax is fixed, you generally cannot deduct business expenses. If your side business involves significant material costs or investments, this might not be the most tax-efficient option.
Specific activities: Not all business activities qualify for the Pausal regime. Make sure yours does.
Simultaneity with employment: The critical thing when you're already employed is understanding how the Pausal contributions interact with your existing employment contributions. When you are employed, your employer pays your social and health contributions. As a Pausal entrepreneur on top of employment, you usually only pay a reduced social contribution (pension) for your Pausal income, as your health insurance is already covered by your main job. This is a huge benefit for employed individuals. You can learn more about this by reading our guide on How Do I Register for the Pausal Tax Regime as a Freelancer in Serbia?.

Standard Entrepreneur (Preduzetnik) and Limited Liability Company (DOO)

While these are viable options for full-time businesses, they are generally overkill and much more complex for a simple side hustle while you're employed.

Standard Entrepreneur (Preduzetnik): This is similar to the Pausal but requires you to keep full business books (double-entry bookkeeping) and pay taxes based on actual profit. This means you'll need an accountant from day one, and the administrative burden is much higher. It's suitable if you have high expenses you want to deduct or if your income regularly exceeds the Pausal limit.
Limited Liability Company (DOO): A DOO is a separate legal entity from you, the owner. It offers limited liability (meaning your personal assets are protected if the business runs into debt) and is suitable for scaling up, bringing in partners, or securing significant investments. However, setting up and maintaining a DOO involves considerably more paperwork, legal fees, administrative costs, and requires a registered capital. For a simple side business, it's almost certainly too much hassle and expense.

For most expats exploring a side business, the "Pausal" route is the clear winner for its balance of legality, simplicity, and favorable contribution structure when combined with existing employment.

Informal Side Gigs: Pros and Cons (and Risks)

Let's be realistic: plenty of people, both local and foreign, do informal "cash-in-hand" side gigs in Serbia. Whether it's helping a neighbour with tech issues, tutoring a kid, or selling crafts at a local market without a formal setup.

Pros (perceived):

No paperwork, no registration.
No taxes or contributions (in theory).
Immediate cash.

Cons and Significant Risks:

Illegal: Any income earned without being declared is considered illegal.
Fines and back taxes: If caught, you could face hefty fines, be required to pay all back taxes and contributions, plus interest. The Poreska Uprava is increasingly sophisticated and shares data with other government agencies.
No legal protection: If a client doesn't pay you, you have no legal recourse. If something goes wrong with your service or product, you could be personally liable.
Difficulty legitimizing later: Trying to legitimize an existing, undeclared income stream can be much harder and more expensive than starting correctly from the beginning.
Impact on residence: For expats, undeclared work can affect your residence permit status, as it indicates you are not complying with Serbian laws.

My advice? Don't risk it. The administrative benefits of the Pausal regime, especially when you're already employed, often outweigh the perceived simplicity of staying "under the radar." It gives you peace of mind and legal standing.

Practical Steps to Officially Start Your Side Business

Once you've decided on the Pausal entrepreneur route, here’s a simplified walkthrough of what you need to do. It might seem like a lot, but it’s manageable, especially if you get some help.

Registering Your Business: The Agency for Business Registers (APR)

This is where your side hustle officially comes into being. The process involves registering with the Serbian Business Registers Agency (Agencija za privredne registre, or APR).

Prepare your documents: You'll need your passport, your Serbian temporary residence card (boravišna dozvola), and potentially your beli karton (white card, address registration). You'll also need to fill out the application form (Obrazac JRPPS).
Choose your business activity (delatnost): This is crucial. You need to select a primary activity code (Šifra delatnosti) that best describes your side business. Be specific, as this affects your Pausal tax calculation. For example, if you're an English teacher on iTalki, you'd choose an education-related code.
Choose your business name: This can be your full name, or a combination of your name and a business name (e.g., "John Smith PR Agencija").
Submit the application: You can submit it in person at the APR office or, increasingly, online if you have an electronic signature. Many expats opt to use a local agency or an accountant to help with this step to ensure everything is correct, as mistakes can cause delays. You can find detailed steps in our guide How to Register as an Entrepreneur (Preduzetnik) in Serbia.
Receive your decision and PIB: Once approved, you'll receive a decision from APR and, crucially, your Business Identification Number (PIB). This PIB is like your business's tax ID.
Poreska Uprava registration: While the APR informs the Tax Administration of your new business, you'll still need to visit your local Poreska Uprava office to formally register as a taxpayer for your new business. This is where you confirm your Pausal status and get your tax and contribution calculation.

This step is essential, as the calculation of your monthly obligations as a Pausal entrepreneur is determined here. They will factor in your declared activity and sometimes your municipality.

Opening a Bank Account and Financial Management

Once your business is registered, you’ll need a separate bank account for your side hustle. While it's tempting to use your personal account, it's generally a bad idea and can complicate tax declarations down the line.

Open a business bank account: Head to any major Serbian bank (like Banca Intesa, Raiffeisen Bank, UniCredit Bank, etc.) with your APR registration decision, PIB, and personal ID documents. Request to open an entrepreneur's account (preduzetnička račun). Make sure to ask about fees, online banking options, and foreign currency accounts if you'll be earning in Euros, Dollars, or other currencies. You can learn more about this in How to Open a Bank Account at a Serbian Bank as a Foreigner.
Manage your finances: Keep meticulous records of all income and expenses related to your side business, even as a Pausal entrepreneur. While you don't deduct expenses for tax purposes, knowing your actual profit is vital for your own financial planning. Use clear invoicing for your clients. Many online tools can help with this.

This is often the most confusing part, but it's where the Pausal regime really shines for employed expats.

Pausal Tax Calculation: As mentioned, the Poreska Uprava calculates a fixed monthly amount. This amount covers:
- Personal Income Tax: The actual income tax component, typically low.
- Pension Contributions (PIO): This is mandatory.
- Health Contributions (RFZO): Crucially, if you are already employed and your primary employer is paying your full health contributions, your Pausal business will often be exempt from paying a separate, full health contribution for your side income. You might still pay a symbolic amount, but it won't be the full rate, saving you a significant sum. This is a key advantage for those balancing a day job and a side business.
- Unemployment Contributions (NSZ): Also usually included.
The exact amount depends on your declared activity, location (Belgrade often has higher base rates), and sometimes your age or professional qualification. These rates are updated periodically, so always get the latest information from the Poreska Uprava or a qualified accountant. Our guide, Understanding the Pausal (Lump-Sum) Tax Regime in Serbia (2027), dives deep into this.
Monthly Payments: You'll receive monthly payment slips (or access them via the ePorezi portal) for your fixed Pausal amount. These must be paid by the 15th of the following month. For example, your January obligations are due by February 15th. Missed payments incur penalties.
Annual Tax Return: Even as a Pausal entrepreneur, you might still need to file an annual tax return (PPPDG form). This is especially important if your total annual income (from both your main job and your side business) exceeds certain thresholds, or if you have any foreign income. This is where services like Taxes for Expats can be invaluable, helping you navigate the complexities of combining different income streams and ensuring compliance. This isn't just about your side gig; it's about your overall financial picture in Serbia, as explained in The Complete Guide to Taxes in Serbia for Expats (2027).

Here's a simplified comparison of the contribution aspect for someone only employed vs. employed with a Pausal side business:

Aspect	Employed Only (Full-time)	Employed + Pausal Entrepreneur (Side Business)
Personal Income Tax	Deducted by employer, flat 10% after non-taxable amount	Paid as part of fixed monthly Pausal sum, separate from employment income.
Pension Contributions	Paid by employer (and employee part deducted from salary)	Paid by employer for main job; reduced pension contribution for Pausal income.
Health Contributions	Paid by employer (and employee part deducted from salary)	Paid by employer for main job; generally exempt from full health contrib. for Pausal income (only symbolic if any).
Unemployment Insurance	Paid by employer	Paid by employer for main job; included in Pausal sum for side business.
Bookkeeping Required	None (handled by employer)	Minimal (no double-entry bookkeeping, just revenue tracking and invoice issue for Pausal)
Annual Tax Declaration	Only if total income exceeds certain thresholds or foreign income.	Likely required, consolidating all income sources, possibly with accountant help.

As you can see, the reduction in health contributions for the Pausal entrepreneur who is already employed is a significant financial relief and makes the option much more appealing.

Common Side Business Ideas and Considerations for Expats

Many expats in Serbia leverage their skills and international experience to create thriving side businesses. The key is to find something that fits your expertise, schedule, and the local demand.

Online Services and Remote Work

This is a natural fit for many expats, given the growing digital economy and the flexibility it offers.

Translation and Localization: If you're fluent in multiple languages, offering translation services is a solid option. Serbia has a demand for translations into and from various European languages.
Online Teaching and Tutoring: Platforms like iTalki (for language teaching) or even private tutoring services for specific subjects (math, science, test prep) are popular. Many local students want to improve their English or other foreign language skills.
Consulting (Marketing, IT, Business Strategy): Leverage your professional background. Many Serbian small and medium-sized businesses could benefit from international expertise in digital marketing, web development, or business strategy. Check out our guide Working Remotely from Serbia: The Definitive Expat Guide (2027) for more ideas.
Content Creation: Blogging, copywriting, social media management, or graphic design can all be done remotely.

These types of businesses often involve low startup costs and can be managed flexibly around a full-time job.

Local Services and Products

While online is popular, there are also opportunities for local, in-person services.

Language Classes/Conversation Groups: Beyond online, in-person language lessons or informal conversation clubs can be very popular.
Niche Consulting for Other Expats: Navigating Serbian bureaucracy, finding reliable services, or even setting up businesses can be a headache for newcomers. If you've been here a while, you could offer your experience as a consultant.
Artisan Crafts and Specialty Foods: If you have a hobby like pottery, jewelry making, baking, or specialty food production, selling these at local markets or online can be a delightful side venture.
Fitness or Wellness Instruction: Yoga, personal training, or specialized workshops (e.g., nutrition) can attract a dedicated clientele, both expat and local.

Remember to consider where the demand is. Belgrade, Novi Sad, and Niš, with their larger expat communities and more developed economies, generally offer more opportunities.

Balancing Your Day Job and Side Hustle

This is crucial for long-term success and avoiding burnout. A side business is exciting, but it adds another layer to your life.

Time Management: Be realistic about how much time you can dedicate. Block out specific hours for your side business and stick to them. Don't let it bleed into your main job's hours or severely impact your rest and personal life.
Energy Levels: A side business requires energy. Ensure you're getting enough sleep and downtime. Pushing yourself too hard will lead to burnout and poor performance in both endeavors.
Clear Boundaries: Keep your side business completely separate from your day job. Do not use your employer's resources (laptops, internet, office supplies, time) for your side hustle. Do not discuss your side business with colleagues or clients of your main job unless it's explicitly cleared and relevant.
Prioritize: Understand that your day job is your primary income source and commitment. Your side business should complement it, not detract from it.

Starting a side business in Serbia as an employed expat is absolutely feasible and can be incredibly rewarding. It provides financial flexibility, a creative outlet, and the satisfaction of building something of your own in your adopted home. Just remember to do your homework, understand the legal and tax requirements, and choose a path that balances opportunity with personal well-being. Good luck!
