Business Account for the Self-Employed: How to Choose
One of the first questions every new entrepreneur asks is: do I need a business account? The short answer is — legally, usually not, but in practice, almost always yes. Mixing personal and business finances in a single account is a recipe for bookkeeping chaos, unnecessary errors in your tax return, and stressful hours spent figuring out which payment was personal and which was business-related. In this article, we'll cover when a business account is legally required, when it's simply worth having, and which features to focus on when choosing one.
Key facts about business accounts for the self-employed in 2026
- Legal obligation to hold a business account applies only to VAT payers (who must notify the tax authority of their account number)
- The cash payment limit in the Czech Republic is CZK 270,000 — amounts above this must be paid by bank transfer
- Self-employed individuals with a data mailbox must file their tax return electronically — tax refunds are paid to a bank account
- A separate account is not the same as a business account — you can also use a second personal account exclusively for business purposes
Is a Business Account Legally Required for the Self-Employed?
Neither the Trade Licensing Act nor the Income Tax Act requires self-employed individuals (OSVČ) to open a dedicated business bank account. However, there are situations where having a bank account becomes effectively mandatory.
When a bank account for business is essential
1. VAT payers
If you are registered for VAT, you are required to notify the tax authority of the bank account number used for your economic activity. This account is published in the VAT payer register at adisreg.mfcr.cz. If you receive payments from other VAT payers, you should accept them into this registered account — the payer has the right to verify whether the payment is going to an account registered with the tax authority. If it isn't, they may be held jointly liable for the supplier's VAT under Section 109 of the VAT Act.
2. Payments exceeding CZK 270,000
Act No. 254/2004 Coll. on the restriction of cash payments stipulates that payments exceeding CZK 270,000 must be made by non-cash means. Without a bank account, you would be unable to legally send or receive larger amounts.
3. Receiving a tax refund
If you are entitled to an income tax refund, the tax authority will transfer it to the bank account you provided in your tax return. Without an account, you essentially can't access the refund.
4. Most clients pay by bank transfer
In practice, the vast majority of business transactions are settled by bank transfer. Running a business without a bank account in 2026 is virtually unthinkable.
Upcoming change: EU cash payment limit
The European Union has approved a directive that will introduce a uniform cash payment limit of 10,000 EUR (approximately CZK 250,000) across all member states from July 2027. The Czech Republic will need to align its current limit accordingly. For entrepreneurs, this means the role of non-cash payments and bank accounts will only grow in importance.
Business Account vs. Personal Account Used for Business
It's important to distinguish between a business account (a banking product specifically designed for companies and entrepreneurs) and a separate personal account used exclusively for business purposes. Both options have their pros and cons.
Business account
A business account is a banking product specifically designed for the needs of entrepreneurs. It typically offers:
- Business/OSVČ identification in payment transactions (company registration number, trading name)
- Integration with accounting software
- Multiple users with different access levels
- Business payment cards
- Overdraft facilities and other business services
- Clear separation from personal finances
Personal account reserved for business use
Many self-employed individuals opt for a pragmatic solution — they open a second personal account (a standard current account for individuals) and use it exclusively for business income and expenses. From a tax record-keeping and transparency perspective, this is a perfectly workable solution.
📊Business account vs. separate personal account
Tip: a personal account may be enough
If you are self-employed with no employees, are not VAT-registered, and have a modest turnover, a second personal account used exclusively for business purposes can be a perfectly adequate — and significantly cheaper — solution. The key is to use it strictly for business transactions and never mix it with your personal account. Account maintenance fees can then be claimed as a tax-deductible business expense.
What to Look for When Choosing an Account
When selecting a business or separate account for your self-employment, there are several key factors to consider. It's not just about the monthly fee — the overall setup needs to match your specific needs.
1. Fees and pricing transparency
The monthly account maintenance fee is just the tip of the iceberg. Read the full fee schedule carefully and pay attention to:
- Account maintenance fee — the basic monthly charge
- Outgoing payments — the cost of domestic transfers, standing orders, direct debits
- Incoming payments — some banks charge for receiving money too
- ATM withdrawals — how many free withdrawals you get per month
- Card payments — any transaction fees for using your payment card
- International payments — fees for SEPA payments and payments outside SEPA
- Currency conversion — if you invoice in EUR or another currency
- Statement fees — monthly statements, certificates for authorities
Example: real monthly account costs
Here's how monthly costs can vary for a typical self-employed person who makes 20 outgoing payments, receives 15 payments, makes 2 ATM withdrawals, and carries out 10 card payments per month.
| Cost item | Account with "zero" fee | Standard business account | |-----------|------------------------|--------------------------| | Account maintenance | CZK 0 | CZK 200 | | 20 outgoing payments | 20 × CZK 5 = CZK 100 | CZK 0 (included) | | 15 incoming payments | 15 × CZK 3 = CZK 45 | CZK 0 (included) | | 2 ATM withdrawals | 2 × CZK 30 = CZK 60 | CZK 0 (included) | | 10 card payments | CZK 0 | CZK 0 | | Total per month | CZK 205 | CZK 200 |
As you can see, a "fee-free" account can end up costing just as much — or even more — than an account with a monthly fee that bundles transactions. Always calculate based on your actual transaction volume.
2. Quality of online and mobile banking
For the self-employed, high-quality digital banking is absolutely essential. When evaluating options, consider:
- Interface clarity — easy navigation through transactions, filtering by date, amount, or counterparty
- Mobile app — the ability to initiate payments and check your account from your phone
- Bulk payments — if you regularly pay multiple invoices at once
- Payment templates — for recurring payments (social insurance and health insurance contributions)
- Data export — the ability to export statements in CSV, XML, or ABO formats for import into accounting software
- Notifications — alerts for incoming payments, upcoming standing order due dates
3. Integration with accounting software and tools
Modern business accounts offer integration with accounting applications via API (banking interface). This enables:
- Automatic downloading of statements into your accounting programme
- Matching payments to invoices
- Automatic recording of income and expenses
If you use a common accounting programme (such as Pohoda, Money S3, Fakturoid, or iDoklad), check whether your chosen bank supports direct integration.
4. Foreign currency payments
If you invoice international clients, pay close attention to:
- The option to hold an account in EUR (or another currency) — a currency account eliminates exchange rate losses
- Conversion rate — what rate the bank uses and what the spread is (the difference between the buy and sell rate)
- SEPA payment fees — EUR payments within the SEPA zone should be subject to the same conditions as domestic payments
- Non-SEPA payment fees — if you do business with clients outside the EU
5. Cash access and branch network
Even in the digital age, the self-employed may occasionally need to:
- Deposit cash — if you accept cash payments from customers
- Withdraw cash — for small operational expenses
- Visit a branch — to handle non-standard situations or obtain certificates for authorities
For digital nomads and IT freelancers
If you work entirely online, have no cash income, and most of your clients are abroad, consider modern fintech solutions. Some banks and financial institutions offer accounts with significantly lower fees for international payments. Make sure, however, that the account meets the requirements for notifying the tax authority (if you are VAT-registered) and that you can easily export statements for your tax records.
6. Overdraft and access to financing
A business overdraft (authorised debit) can be a safety net during periods when you're waiting for invoices to be paid. When choosing an account, find out:
- Overdraft availability — whether the bank offers an overdraft on the account
- Overdraft limit — the maximum limit you can access
- Interest rate — how much you'll pay when using the overdraft
- Eligibility conditions — most banks require a track record in business (typically 1–2 years)
Benefits of a Separate Account for Business
If you're still on the fence about opening a separate account for your business, consider these practical advantages.
Clarity and time savings
The strongest argument for a separate account is clarity. When personal and business finances share one account, you have to manually distinguish which transactions are business-related and which are personal every time you look at a statement. This takes time and increases the risk of errors.
With a separate account, it's straightforward: every transaction on the business account is a business transaction. Exporting a statement directly corresponds to your tax records.
Simpler tax record-keeping
Tax records require a clear, verifiable separation of business income and expenses. With a separate account:
- Bank statements directly correspond to your income and expense records
- Any transaction is easy to trace
- The risk of errors when filing your tax return is minimised
- Your accountant (or accounting software) works only with business transactions
A professional impression
If you list an account on your invoices that also receives personal payments, it doesn't look particularly professional. A dedicated business account signals to clients and business partners that you take your work seriously.
Better cash flow visibility
With a separate account, you can see at any moment exactly how much money your business has available. You don't need to subtract personal income and expenses. The account balance directly reflects your business cash position.
Easier handling of tax authority audits
In the event of a tax audit, you'll need to document all business income and expenses. With a separate account, you simply provide the statements from your business account. If everything is on a single personal account, you'll have to explain every transaction — and the tax authority has the right to examine your complete account statements.
In practice: what the tax authority can do
During a tax audit, the tax authority has the right to request complete statements from any account used to receive business income. If you use your personal account for business as well, the auditor will see your private transactions too. A separate business account protects you from unnecessarily exposing your personal finances.
How to Set Up Your Business Account Properly
Once you've opened an account, it's important to set it up correctly to get the most out of it.
Standing orders for regular payments
📋Set up standing orders for key payments
- Social insurance contributions — monthly contributions to pension insurance, due by the 20th of the following month. In 2026, the minimum contribution is CZK 4,759 (main activity). You'll find the account number and variable symbol at the ČSSZ ePortal.
- Health insurance contributions — monthly contributions due by the 8th of the following month. In 2026, the minimum contribution is CZK 3,306. Payment details are available from your health insurance provider.
- Income tax advance payments — if you are required to pay quarterly or semi-annual income tax advances. You'll find the amounts and deadlines in your tax authority notice or in the "Personal Tax Account" section at the MOJE daně portal.
- VAT advance payments — if you are VAT-registered and pay instalments.
- Insurance premiums (liability, property) — if you hold professional liability or property insurance.
Categorising transactions
Many banking apps allow you to add notes or labels to transactions. Make use of this feature to simplify your record-keeping:
- Add an invoice number or expense description to each payment
- Distinguish between types of expenses (materials, services, travel, entertainment)
- Tag income entries with the name of the client the payment came from
Regular account reviews
Get into the habit of checking your account at least once a week to verify:
- Which invoices have been paid and which are overdue
- Whether all standing orders have gone through (insurance contributions, tax payments)
- What the current balance is and whether it will cover upcoming expenses
Account Fees as a Tax-Deductible Expense
Fees for maintaining a business account — or a separate personal account used exclusively for business — are tax-deductible expenses. You can claim them as actual expenses when filing your tax return.
This applies to:
- Monthly account maintenance fees
- Transaction fees (outgoing/incoming payments)
- Payment card fees
- Online banking fees
- International payment and currency conversion fees
- Overdraft interest
Important note if you use flat-rate expenses
If you claim flat-rate expenses (calculated as a percentage of income), you cannot claim account fees separately — they are already included in the flat rate. However, a separate account will still make it easier to keep track of the income you report in your tax return.
Frequently Asked Questions (FAQ)
Do I need to notify the tax authority of my account number?
If you are a VAT payer, you are required to notify the tax authority of the bank account number you use to receive business payments. This account will be published in the VAT payer register. Non-VAT payers are not required to do this, but they do provide their account number in their tax return for the purpose of receiving any tax refund.
Can I use an account held at a foreign bank?
Yes, but make sure the account has an IBAN format and that you can make payments to Czech accounts from it (social insurance contributions, taxes). Some foreign accounts may not support CZK payments or may charge high conversion fees.
How many accounts can a self-employed person have?
There is no limit on the number of accounts. You can have one main business account and additional accounts for specific purposes — for example, a EUR currency account, a savings account for your tax reserve, or a separate account for VAT.
Can I open a business account before I start trading?
Most banks require a valid company registration number and a trade licence. This means you can only open the account after registering with the Trade Licensing Authority. Some banks, however, allow a "pre-registration" and activate the account once you provide your registration number.
What happens to a business account when I stop trading?
The account doesn't close automatically when you cease trading. We recommend keeping it active for several months after winding down — to receive any final payments from clients, collect tax refunds, and handle potential disputes. You can close the account once those matters are resolved.
Is interest earned on a business account taxable income?
Yes, interest on a business account counts as business income and is included in your income tax base. For personal accounts, interest is taxed at source by the bank through a withholding tax.
Practical Checklist for Choosing an Account
📋Steps for choosing a business account
- Assess your needs — how many transactions do you make each month? Do you need foreign currency payments? How important is a branch network?
- Compare total costs — not just the monthly fee, but total costs based on your transaction volume.
- Check accounting software integration — if you use a specific programme, verify compatibility.
- Try the mobile app — the quality of digital banking is crucial for day-to-day use.
- Ask about overdraft facilities — what are the conditions, maximum limit, and interest rate?
- Find out about international payment conditions — if you invoice abroad, compare exchange rates and fees.
- Read the entire fee schedule — pay attention to hidden charges (certificates, setting changes, paper statements).
- Open the account and set up standing orders — for insurance contributions and tax advance payments.
Summary
Separating your business and personal finances is one of the best things you can do for your self-employment. You'll save time on record-keeping, reduce the risk of errors in your tax return, and gain a clear picture of how your business is performing financially. Whether you opt for a traditional business account or open a second personal account dedicated solely to business depends on your specific needs and transaction volume.
