Software developers, IT consultants, DevOps specialists, cybersecurity professionals and product advisers often have a simple commercial model: a small number of foreign clients, recurring monthly invoices and mostly digital costs. The accounting still needs the correct structure, VAT treatment and audit trail.
Freelancer or company for IT consulting?
Self-employed professional
Often suitable when you sell your own expertise, work alone, have limited costs and want lighter administration.
Bulgarian company
Often suitable for hiring, subcontracting, retaining profit, protecting a business brand or meeting corporate-client requirements.
A freelancer may qualify for a 25% statutory recognised expense deduction for personal income tax, while a company accounts for documented business income and actual deductible expenses. Compare the full result: tax, social security, profit extraction, accounting cost, liability and plans for growth. Our freelancer vs company guide explains the wider decision.
Foreign IT clients and VAT
Many Bulgaria-based IT professionals provide general B2B services to companies in the EU, UK or US. For an EU business customer, the general rule commonly places the supply where the customer is established. The invoice may use reverse charge, but the Bulgarian supplier may first need special VAT registration and will commonly have VIES reporting.
For a genuine business client outside the EU, Bulgarian VAT is commonly not charged under the general B2B place-of-supply rule. Do not rely on country alone: document that the customer is acting as a business and confirm whether the precise service falls under an exception.
Work for private individuals, software sold as a standardised digital product, SaaS subscriptions, online courses and marketplace sales can follow different rules from bespoke B2B consulting.
Foreign software and cloud purchases
Inbound services are frequently missed. Cloud hosting, source-code tools, advertising, AI products, SaaS, app-store fees and professional platforms supplied from abroad may require Bulgarian reverse-charge treatment. This can create a VAT registration issue even before you invoice an EU client.
A robust IT consulting invoice
An invoice should identify supplier and customer, addresses and tax identifiers where applicable, invoice number and date, service period, clear service description, amount and currency, and the correct VAT basis or reverse-charge wording.
“IT services” may be too vague on its own. Use wording consistent with the contract—such as software development services for a stated period—without exposing confidential technical information. Keep the signed contract, statements of work, acceptance evidence, timesheets where required, invoice, payment record and VAT-number validation.
IT expenses and supporting documents
For a company, potentially relevant costs can include computers and peripherals, software, cloud infrastructure, cybersecurity tools, coworking, professional insurance, training, accounting and bank fees. Deductibility and VAT recovery depend on business purpose, proper invoices and the applicable rules; durable equipment may need to be treated as an asset rather than an immediate expense.
For an individual using the statutory expense deduction, keeping purchase evidence remains useful, but actual costs do not simply replace the standard deduction in the personal income-tax calculation.
Recommended monthly accounting workflow
- issue sequential invoices and match them to contracts and payments;
- collect supplier invoices for software, cloud and platforms—not only card receipts;
- separate business and personal transactions;
- record foreign-currency amounts using the correct reporting method;
- validate EU VAT numbers and preserve the result;
- complete VAT and VIES filings by the applicable deadlines;
- review social security, payroll or management remuneration as relevant.
Contract and substance risks
One long-term client does not automatically make independent consulting invalid, but the facts matter. Control over working time, exclusivity, use of the client’s tools, economic dependence and integration into the client’s organisation can affect employment, permanent-establishment and cross-border social-security analysis.
Remote work from Bulgaria can also affect tax residence and the client’s position. This is particularly important when the consultant has recently moved countries or performs work physically from several jurisdictions.
Common accounting mistakes by IT consultants
- registering for VAT only after the first EU invoice;
- ignoring reverse charge on foreign SaaS and cloud costs;
- using a personal name, company name and payment account inconsistently;
- keeping bank transactions without valid supplier invoices;
- treating hardware automatically as an immediate expense;
- mixing bespoke consulting with digital-product sales for VAT purposes;
- choosing a company based only on the headline corporate tax rate.
Frequently asked questions
Can an IT consultant work as a freelancer in Bulgaria?
Often yes, when the activity genuinely fits a free profession. The exact registration and social-security position should be confirmed before work starts.
Do I charge VAT to an EU company?
For general B2B IT services, Bulgarian VAT is commonly not charged and reverse charge applies, but special Bulgarian VAT registration and VIES reporting may be required.
Do I charge VAT to a UK or US company?
For general B2B services, Bulgarian VAT is commonly not charged. Customer business status, service type and evidence still need review.
Can I deduct a laptop and software?
A company may deduct properly documented business costs subject to the tax and accounting rules; equipment may be capitalised. A freelancer using statutory recognised expenses does not normally substitute itemised actual costs for that deduction.
How often should IT accounting be updated?
Monthly processing is the safest model, particularly where VAT, VIES, foreign suppliers or recurring cross-border invoices are involved.
