What business expenses can I claim in Bulgaria?
Bulgarian companies can deduct expenses that are wholly and exclusively incurred for business purposes from taxable profit. Common deductible expenses include salaries, rent, utilities, professional fees, marketing, and depreciation. Non-deductible items include fines, personal expenses, and representation costs are only 50% deductible.
Detailed Explanation
Under the Bulgarian Corporate Income Tax Act (CITA), a company's taxable profit is calculated by adjusting accounting profit for a set of specific additions (non-deductible expenses) and deductions (additional tax reliefs). The underlying principle is that expenses must be wholly and exclusively incurred in connection with the company's business activity to be deductible.
Fully deductible expenses (examples)
- Salaries and wages (including gross salary plus employer social insurance contributions)
- Rent and utilities for business premises
- Professional fees (accountancy, legal, consulting, audit)
- Marketing and advertising costs (digital ads, print, events, trade shows)
- Travel and subsistence for business purposes (with supporting documentation)
- Software subscriptions and SaaS tools used for the business
- Office supplies and consumables
- Cost of goods sold (purchases of stock or raw materials)
- Interest on business loans (subject to thin capitalisation rules)
- Research and development expenditure
- Insurance premiums for business assets and liability
- Repairs and maintenance of business assets
- Tax depreciation on fixed assets (see depreciation rates below)
Non-deductible expenses (key categories)
The CITA lists specific categories of expenses that are not deductible, regardless of how they are treated in the accounts:
- Fines, penalties, and surcharges imposed by courts, the NRA, or other public bodies
- Personal expenses paid through the company (including personal portions of mixed-use costs)
- Expenses not supported by a valid document (invoice, receipt, contract)
- Distributions to shareholders disguised as expenses (deemed distributions)
- Expenses related to exempt income
- Some categories of donations (with limited exceptions for approved charities)
50% deductible: representation expenses
Representation expenses are only 50% deductible for CIT purposes. The CITA defines representation expenses broadly as costs incurred in the reception, entertainment, or business promotion of business partners, clients, or associates. This includes: - Business meals and entertainment - Corporate hospitality events - Gifts to clients or partners (above minor value) - Expenses for showrooms or reception areas used for client entertainment
If a meal is genuinely part of a business negotiation or management meeting, it is representation. If it is a staff team-building or wellbeing event for employees, a different treatment may apply. The 50% limit is applied in the annual CIT return by adding back 50% of the representation expenses.
Thin capitalisation (interest deductibility)
Interest on loans from related parties is subject to thin capitalisation rules. If a company's debt to related parties exceeds three times its equity (the 3:1 debt-to-equity ratio), interest on the excess debt is non-deductible. This is designed to prevent profit-shifting via excessive intra-group loans.
Tax depreciation rates
For CIT purposes, the CITA sets maximum annual depreciation rates for different asset categories:
- Buildings, structures, and transmission equipment: 4% straight-line per year
- Machinery, production equipment, vehicles: 30% straight-line per year
- Computers, computer peripherals, software: 50% straight-line per year
- Goodwill: 15% straight-line per year
- Intangible assets (patents, licences, brands): 15% per year
- Other depreciable assets: 15% per year
If the accounting depreciation rate is higher than the CITA maximum, the excess must be added back in the CIT return (temporary difference carried forward). If the accounting rate is lower, the company can claim the higher CITA rate for tax purposes, creating an accelerated depreciation benefit.
Documenting expenses
All deductible expenses must be supported by a valid primary document: an invoice from the supplier (for services over BGN 1,000), a receipt, or a contract. For VAT purposes, the invoice must include the supplier's and buyer's VAT numbers, the correct VAT amount, and a description of the supply. Informal payments without documentation are non-deductible and may attract NRA scrutiny.

Real-World Examples
Software company claiming computer depreciation
A Bulgarian EOOD buys a BGN 4,000 laptop for its developer. Under CITA, computers depreciate at up to 50% per year. In year one, the company claims BGN 2,000 of tax depreciation, reducing taxable profit by BGN 2,000. This saves BGN 200 in CIT (10% x BGN 2,000). In year two, the remaining BGN 2,000 book value is fully depreciated, with another BGN 200 CIT saving.
Representation expenses at a 50% limit
An OOD spends BGN 6,000 on client lunches, hospitality events, and corporate gifts during the year. In the accounts, all BGN 6,000 is expensed. In the CIT return, BGN 3,000 (50%) is added back as non-deductible. The company pays CIT on the extra BGN 3,000 at 10%, costing an additional BGN 300 in tax compared to a fully deductible expense.
NRA challenge on undocumented expenses
During an NRA audit, an EOOD cannot provide invoices for BGN 15,000 of claimed expenses. The NRA disallows all BGN 15,000, raising the taxable profit by BGN 15,000. CIT assessment: BGN 1,500 extra tax plus interest and a 10-20% accuracy penalty. The missing documentation cost the company significantly more than the original tax saving.
Common Mistakes to Avoid
- Claiming personal expenses (personal car use, home broadband, personal holidays) as business expenses without a proper allocation methodology: the NRA audits personal vs business usage, and the personal element must be added back.
- Not applying the 50% cap on representation expenses in the annual CIT return: simply expensing all business entertainment in the accounts without the CIT adjustment leads to a tax underpayment.
- Claiming depreciation at higher rates than the CITA maximum without creating the required temporary difference adjustment in Form 1, leading to overstated deductions and potential penalties.
- Making payments to suppliers without obtaining a valid VAT invoice: undocumented expenses are fully disallowed, and the NRA treats missing documentation as evidence of a phantom transaction.
Frequently Asked Questions
Can I claim my home office as a business expense in Bulgaria?
Yes, but only the portion used exclusively for business. A reasonable apportionment method (for example, floor area used for business as a percentage of total floor area, applied to rent, utilities, and broadband costs) is acceptable. You need to document the basis for the allocation and apply it consistently. The personal portion is not deductible.
Are salaries paid to family members deductible?
Yes, if the salary is at a market rate for the work performed and the family member is genuinely employed and working. Salaries to related parties (including family members) are scrutinised by the NRA for transfer pricing and disguised dividends. Inflated salaries paid purely to reduce taxable profit are non-deductible and can be reclassified.
What is the tax depreciation rate for vehicles in Bulgaria?
Vehicles fall under the machinery and production equipment category, with a maximum CITA depreciation rate of 30% per year straight-line. A BGN 30,000 car would be fully depreciated over approximately 3.3 years for tax purposes. There are no luxury car restrictions equivalent to the UK's, but the car must be used wholly for business to be fully deductible.
Can I deduct VAT I have paid on business expenses?
Yes, but through the VAT system, not the CIT system. If you are VAT-registered, you recover input VAT on business expenses via the monthly Vat14 return. For CIT purposes, you deduct the net-of-VAT cost (since you have already recovered the VAT). If you are not VAT-registered, the VAT-inclusive cost is your deductible expense for CIT.
Are fines from the NRA or other public bodies deductible?
No. Fines, penalties, and surcharges imposed by the NRA, courts, customs authorities, or any other public body are explicitly non-deductible under CITA. They cannot be added back as a deductible expense regardless of how they are treated in the accounts. The same applies to late payment interest on taxes.
Practical Tips
- Set up separate expense categories for representation in your accounting system and track them through the year: the 50% add-back in Form 1 requires knowing the exact annual total.
- Obtain a valid invoice for every expense over BGN 100 immediately: chasing documentation after the fact, especially from small or foreign suppliers, is difficult and missing invoices make the expense non-deductible.
- For assets like computers and software, claim the full CITA depreciation rate (50% per year) rather than the accounting rate if your accounting software uses a slower rate: the higher tax depreciation is a legitimate and valuable cash flow benefit.
- Document the business purpose of travel and subsistence expenses at the time of the trip: a brief note on what the meeting was and who attended is sufficient but essential if the NRA questions the deductibility.
