Quick Answer: Depreciation of Assets
In Bulgaria, businesses depreciate assets using the straight-line method, spreading the cost of tangible and intangible assets over their useful life. Depreciation reduces taxable profit annually and must follow consistent accounting policies supported by proper documentation.
Introduction
Depreciation is a key element of accounting and tax planning in Bulgaria. It allows businesses to spread the cost of assets over their useful life instead of expensing them fully in the year of purchase. When applied correctly, depreciation improves cash flow, supports accurate financial reporting, and ensures compliance with Bulgarian tax rules.
This guide explains which assets can be depreciated, how depreciation is calculated, applicable rates, and how asset disposal is treated for tax purposes.
What Is Depreciation?
Depreciation is the systematic allocation of the cost of a tangible or intangible asset over its useful life. Rather than deducting the full purchase cost immediately, businesses recognize depreciation as an annual expense, reducing taxable income over several years.
What Assets Can Be Depreciated?
Tangible Assets
- Machinery and equipment
- Vehicles (company cars, delivery vans)
- Office furniture and fixtures
- Buildings (excluding land)
Intangible Assets
- Software licenses
- Patents and trademarks
- Licenses and permits
Note: Land is not depreciable, as it does not lose value over time.
Depreciation Method Used in Bulgaria
For corporate tax purposes, Bulgarian practice primarily uses the straight-line method.
Straight-Line Formula:
Annual Depreciation = (Asset Cost – Residual Value) / Useful Life
Useful Life and Depreciation Rates in Bulgaria
Below are commonly applied useful lives and annual depreciation rates.
Depreciation Rates Table
| Asset Type | Useful Life | Annual Depreciation Rate |
|---|---|---|
| Machinery and Equipment | 5 years | 20% |
| Vehicles | 5 years | 20% |
| Office Furniture | 10 years | 10% |
| Buildings | 25 years | 4% |
| Software | 3 years | 33.33% |
Residual Value
A residual value (often assumed at 10%) is not legally mandatory. Assets may be depreciated down to zero if this reflects realistic use and company accounting policy. The key requirement is consistency and reasonable justification.
How to Calculate and Record Depreciation
Step-by-Step Calculation
- Determine asset cost
Include purchase price, delivery, and installation costs. - Subtract residual value (if applied)
- Divide by useful life
Example
A company purchases machinery for EUR 50,000.
- Residual value: EUR 5,000
- Depreciable amount: EUR 45,000
- Useful life: 5 years
- Annual depreciation: EUR 9,000
Recording Depreciation
- Depreciation is recorded as an expense in the profit and loss statement
- Accumulated depreciation is reflected in the balance sheet
Tax Implications When Disposing of Assets
Book Value Formula
Book Value = Original Cost – Accumulated Depreciation
Taxable Result
- Sale price > book value → taxable gain
- Sale price < book value → deductible loss
Example
An asset with a book value of EUR 10,000 is sold for
EUR 12,000.
- Taxable gain: EUR 2,000
Best Practices for Managing Depreciation
- Maintain detailed asset registers
- Review useful lives periodically
- Plan disposals with tax impact in mind
- Use accounting software for automation
- Consult professionals for complex cases
Frequently Asked Questions (FAQ)
What depreciation method is used in Bulgaria for tax purposes?
For corporate tax purposes, depreciation is typically calculated using the straight-line method, where the asset’s depreciable value is spread evenly over its useful life. Companies must apply a consistent method supported by documentation.
What is the depreciation rate for vehicles in Bulgaria?
Vehicles are commonly depreciated over 5 years, corresponding to an annual straight-line depreciation rate of 20%. Treatment may vary depending on business use and internal accounting policy.
Can software be depreciated in Bulgaria?
Yes. Software and similar intangible assets are typically depreciated over 3 years, resulting in an annual depreciation rate of 33.33%. Supporting documentation such as invoices and license terms should be retained.
Is residual value mandatory for depreciation?
No. Residual value is not mandatory and depends on company policy and realistic resale expectations. Assets may be depreciated down to zero if justified and consistently applied.
How does depreciation affect corporate income tax?
Depreciation reduces taxable profit by allowing the asset cost to be deducted gradually over time. This can lower corporate income tax while ensuring compliance with accounting and tax rules.
What happens when a depreciated asset is sold?
The tax result is generally the difference between the sale price and the asset’s book value. A higher sale price creates a taxable gain; a lower price results in a deductible loss.
