What does the crypto tax calculator calculate?
The crypto tax calculator is an online tool that calculates taxes on realized cryptocurrency profits according to Bulgarian legislation for 2025. The calculator shows the profit or loss from cryptocurrency transactions (difference between sale and purchase price), the due tax at a rate of 10% on realized profit, and the net profit after tax. The calculator works with a simplified model (one purchase and one sale) and is useful for individuals who have realized crypto profits and want to understand their tax obligations, plan tax payments, and comply with tax regulations. It helps you make informed decisions about crypto investments and understand the real cost of crypto trading after taxes.
How to use the crypto tax calculator?
When to use the crypto tax calculator
Useful when you have already realized profit (sold crypto for fiat or another cryptocurrency) and want to see what tax is due according to Bulgarian legislation for 2025.
Step by step:
- Enter the purchase price of the cryptocurrency in BGN.
- Enter the sale price in BGN.
- Enter the quantity (number of coins / tokens).
- The calculator calculates the profit and the due tax at a rate of 10%.
Important:
- The calculator is for simplified transactions (one purchase and one sale).
- For many transactions and complex portfolios, it's a good idea to consult with an accountant.
What the results show:
- Profit/loss – the difference between the sale and purchase price
- Due tax – 10% of the realized profit (if any)
- Net profit after tax – what remains after paying the tax
Example with specific numbers
Example: Bitcoin purchase and sale with realized profit
- Purchase price: 50,000 BGN (for 1 BTC)
- Sale price: 70,000 BGN (for 1 BTC)
- Quantity: 1 BTC
- Realized profit: 70,000 - 50,000 = 20,000 BGN
- Due tax (10%): 20,000 × 10% = 2,000 BGN
- Net profit after tax: 20,000 - 2,000 = 18,000 BGN
When selling Bitcoin with a profit of 20,000 BGN, the due tax is 2,000 BGN (10% on realized profit). Net profit after paying tax is 18,000 BGN. It's important to note that for annual profits below 6,000 BGN there is no tax, but this needs to be checked for the entire tax period.
Sources and notes
The calculator uses current tax rates for 2025, established by the Income Tax Act. Tax on capital gains from cryptocurrencies is 10% on realized profit (the difference between sale and purchase price). For annual profits below 6,000 BGN there is no tax. The calculator works with a simplified model (one purchase and one sale) and does not cover complex portfolios with multiple transactions, FIFO method for many transactions, or exchange fees. For accurate calculations with complex portfolios, many transactions, or specific cases, always consult with NAP or an accountant.

- Annual limit of 6,000 BGN – for profits below this limit there is no tax, but this is not automatically accounted for
