What Expenses Are Tax-Deductible for Bulgarian Companies?

To know what expenses are tax-deductible for Bulgarian companies, you include ordinary and necessary costs that are directly linked to earning business income—such as staff, office, software, travel, vehicles, marketing, professional services, and depreciation—while excluding or limiting personal, luxury, entertainment, and undocumented costs in 2026.

Deductible Expenses in Bulgaria—The Big Picture

Bulgarian corporate tax is calculated on taxable profit: revenue minus allowable expenses. The Ministry of Finance publishes the legal framework and changes; see the official resources at minfin.bg. If you’re new to the full calculation from revenue to tax due, read our simplified walk-through on how to calculate corporate tax in Bulgaria and the broader context in Bulgaria’s corporate tax rate overview.

How the EU VAT Framework Interacts with Your Expenses

VAT rules are harmonized at EU level. On your expenses, input VAT is normally reclaimable if the cost is used for taxable business activities and not explicitly blocked. For authoritative guidance and cross-border rules, consult the European Commission VAT pages, and the legal base in the EU VAT Directive on EUR-Lex. Domestic administration and forms are handled by the National Revenue Agency.

Input VAT on Expenses—Reclaim or Blocked?

Expense	Input VAT Position	Condition	What to File/Keep	Common Error
Office rent & utilities	Usually reclaimable	Registered for VAT and taxable use	VAT invoice, lease	Forgetting to update address
Software subscriptions	Reclaimable	Business use and valid invoice	VAT invoice, contract	Using personal email/accounts
Travel & hotels	Varies by country & purpose	Business trip, evidence required	Itinerary, receipts, agenda	No link to revenue activity
Entertainment & gifts	Often blocked or limited	Modest gifts may be allowed	Gift policy, receipts	Calling entertainment “marketing”
Vehicles	Partially reclaimable	Business usage % recorded	Logbook, fuel receipts	No usage split recorded

Deep-Dive: The Most Common Deductible Categories

1) Staff Costs

Salaries, social security, mandatory insurance, and performance bonuses are deductible when paid for work that produces income. Non-business gifts and private benefits are not.

2) Office, Utilities, and Registered Address

Rent, service charges, electricity, water, internet, and cleaning are deductible if tied to your operations. For mixed-use (e.g., home office), apply a reasonable business percentage based on area or time.

3) Software, Cloud, and Tools

Licenses for productivity, CRM, analytics, dev tools, storage, and cybersecurity are deductible. Keep your company data on each invoice and centralize subscriptions.

4) Travel, Per-Diems, and Client Meetings

Plane/train/bus tickets, mileage for business journeys, hotels, and reasonable meals are deductible when trips have a clear business agenda. Leisure and companion costs are not.

Business Travel—Policy Snapshot

Cost Type	Deductible?	Evidence	Founder Tip
Transport (air/rail/road)	Yes, business trips	Tickets, itinerary, meeting notes	Attach calendar invites
Hotels	Yes, reasonable	Hotel invoice with company data	Prefer B2B invoices
Meals	Limited/Reasonable	Receipt + attendee/purpose	Use a simple meal policy
Leisure, companion	No	—	Split personal costs

5) Vehicles—Company vs Mixed Use

For company cars, deduct lease, insurance, maintenance, and fuel proportionate to business use. For mixed usage, keep a logbook and apply a fair split. Private trips are not deductible.

Vehicles—Two Practical Approaches

Approach	When to Use	What You Deduct	Evidence	Risk
Company car	Dedicated business use	Lease, fuel, insurance, repairs	Lease, invoices, logbook	Private use must be minimal
Mixed-use allocation	Owner-driver, occasional trips	Business % of all costs	Logbook, trip purpose	Weak logs → disallowances

6) Marketing, Sales, and Partnerships

Performance ads, creatives, SEO tools, sponsorships linked to revenue, trade-show fees, and samples are deductible. Lavish entertainment is not.

7) Professional Services & Compliance

Accounting, legal, payroll, audit, and compliance subscriptions are deductible when tied to the business. Private legal matters are not.

8) Equipment, CapEx, and Depreciation

Hardware, furniture, and larger tools may be capitalized and depreciated over useful life. Small tools and supplies are usually expensed. Keep an asset register for clarity.

9) R&D, IP, and Bad Debts

Research costs, prototyping, patent filings, and technical documentation are deductible when they support the business. Write-offs for uncollectible invoices may be deductible if you show reasonable attempts to collect.

Remote Founders, Cross-Border Expenses, and Evidence

Remote EOOD/OOD owners can run everything paperless: collect e-invoices, bank statements, and delivery proof; mirror the language and currency in your ledger (EUR is fine). Cross-border expenses need extra care on VAT and place-of-supply rules. Legal bases and updates live on EUR-Lex, while Bulgarian practice and forms are administered through NRA portals.

Cross-Border Expenses—What to Check

Expense	Place of Supply (Typical)	VAT Outcome	What to Keep	Founder Tip
EU software (B2B)	Customer location	Reverse charge, no foreign VAT	Supplier VAT, your VAT/EIK	Check the invoice has your VAT ID
Non-EU SaaS	Customer location	May charge local tax outside EU	Invoice, tax line if any	Capture supplier tax status
Hotels abroad	Where the hotel is located	Local VAT may be non-reclaimable	Hotel invoice, itinerary	Focus on profit deduction, not VAT
Freelancers abroad	Supplier’s country or your location	No VAT if reverse-charged	Contract, invoice, bank proof	Collect tax residence statements

Company Form, Ownership, and Practical Differences

EOOD (single-owner OOD), OOD (multi-owner), EAD (single-owner JSC), and AD (JSC) all follow the same core logic for deductibility. Differences show up in governance, audits, equity plans, and access to investment—not in whether a cost is ordinary and necessary.

Forms vs Deductibility—What Actually Changes

Form	Owners	Governance	Payroll/Director Pay	Deductibility Impact	Use Case
EOOD	1	Director managed	Owner-director remuneration	Same rules as OOD	Solo founders
OOD	2+	Shareholder agreements	Director contracts	Same rules as EOOD	Agencies, studios
EAD	1	Board/sole director	Board-approved packages	No change on what’s deductible	Scale-up prep
AD	2+	One/two-tier board	Remco, audit committee	Audit may increase scrutiny	Investor-ready companies

Documentation: Your Audit-Ready Checklist

Auditors look for a clear link from expense to revenue activity, and for consistent, complete documentation month by month.

Audit-Ready Evidence by Expense Type

Expense	Mandatory Documents	Optional but Helpful	Retention Habit
Payroll	Employment contracts, payroll sheets	KPIs, bonus memos	Store monthly packs
Rent & utilities	Lease, invoices, bank proofs	Photos of signage/workspace	Renewals filed annually
Software/SaaS	Invoices with company data	License assignments	Centralize vendors
Travel	Receipts, itinerary	Meeting agenda, minutes	Attach to claim
Vehicles	Lease, insurance, fuel receipts	Logbook records	Weekly updates
Professional services	Engagement letter, invoices	Work reports	Quarterly review
