Can a Dormant Company Have a Bank Account and Still File Dormant Accounts? updated March 2026

Yes — a dormant company can have a bank account and still file dormant accounts with Companies House, but only if no significant accounting transactions occur through it during the financial year.

Updated March 2026: Having the account itself does not break dormancy. However, even a tiny amount of bank interest, monthly maintenance fees, or any other transaction will usually mean the company is no longer considered dormant for Companies House purposes — and definitely not for HMRC Corporation Tax. Many directors keep a bank account open “just in case” and are surprised when it triggers full accounts and a Corporation Tax return.

At Filing Accounts, we help hundreds of directors every year maintain proper dormant status while safely managing any necessary bank accounts. Contact us today for a free dormancy check and fixed-price dormant accounts filing.

What Does “Dormant” Actually Mean for Companies House?

Companies House uses a very specific definition: A company is dormant if it has had no significant accounting transactions in the financial year.

Significant accounting transactions = anything that must be recorded in the company’s accounting records (e.g. sales, purchases, expenses, bank interest received, bank charges paid).

Transactions that do NOT break dormancy (official exemptions):

• Filing fees paid to Companies House
• Late filing penalties
• Money paid for shares when the company was first incorporated

Can a Dormant Company Have a Bank Account? (The Practical Answer)

Yes — technically. Opening or maintaining a bank account is not itself a “transaction”. The account can sit open with a zero or nominal balance.

But in practice it is risky. Most banks automatically:

• Charge monthly or quarterly maintenance fees
• Pay interest (even a few pence)

These small movements are considered significant accounting transactions by Companies House and will break dormant status.

Allowed vs Not Allowed Transactions (2026 Rules)

Key difference:

• Companies House looks only at significant accounting transactions.
• HMRC is stricter — any income at all (including bank interest) means the company is no longer dormant for Corporation Tax and must file a CT600 return.

Step-by-Step: How to Keep a Bank Account and Still File Dormant Accounts Safely

1. Open or keep the account only if absolutely necessary Many directors choose to close the business bank account entirely to eliminate risk.
2. Monitor for automatic transactions Contact your bank and request “no interest” or “no charges” if possible (some banks allow this for dormant accounts).
3. Check the balance regularly Ensure the account shows zero activity every quarter.
4. Prepare dormant accounts as normal Use the simple online template showing only share capital (and possibly a nominal cash balance if the account is held).
5. File with Companies House Submit dormant accounts within 9 months of your accounting reference date (21 months for first accounts). Director ID verification is mandatory.
6. File your Confirmation Statement (CS01) Still required every year (£50 fee in 2026).
7. Notify HMRC separately Tell HMRC the company is dormant so they do not send you a Corporation Tax return.

Pro tip: If your dormant company already has a bank account with even £1 of interest showing, it is safer to file as a non-trading (non-dormant) company rather than risk rejection or penalties.
