Lock your accounts

This article explains how to lock your accounts in FreeAgent and what happens when there is an account lock in place.

Locking your accounts in FreeAgent prevents you from editing any of the data that makes up your accounts, up to a particular date. This date is set when the lock is applied.

Your accounts will either lock automatically as the result of certain events, or you can lock your accounts manually.

Once a lock has been applied, you will have the option to remove the lock from your accounts.

Navigating to the Account Locking area

Select ‘Settings’ from the drop-down menu at the top-right of the screen and select ‘Account Locking’.

When your accounts are locked automatically

Your accounts will lock automatically as a result of the following events:

• If you’re a sole trader or unincorporated landlord and you have filed your Self Assessment tax return or marked it as filed, your accounts will be automatically locked up to the end of your business’s basis period.
• If you run a limited company and you or your accountant have approved and signed your end-of-year accounts, your accounts will be automatically locked up to the end of your accounting year.

The date up to which the accounts are locked will be shown under ‘Active account locks’.

Locking your accounts manually

To lock your accounts manually, you'll need full (level 8) access to your FreeAgent account. If your accountant has level 8 access to your FreeAgent account, or they are a FreeAgent Partner, they may lock your accounts on your behalf.

Enter a date in the 'Lock Accounts until' field.

You'll see a range of valid lock dates below the ‘Lock Accounts until’ box.

FreeAgent generates this date range using the following principles:

• If you’re not registered for VAT, the most recent date up to which FreeAgent will allow you to lock your accounts is seven days prior to the current date.
• If you are VAT registered for VAT, the most recent date up to which FreeAgent will allow you to lock your accounts is the end of the period covered by your last filed VAT return, and you'll not be able to apply the lock until at least seven days after this date. For example, if your last filed VAT return covered the period ending 31st October, you would only be able to lock your account up to that date, and you would have to wait until 7th November or later to apply the lock.

Please note that if you have filed a Self Assessment tax return through FreeAgent and an automatic lock has been applied, the earliest valid lock date will be the start of the current tax year. For example, if you have filed a Self Assessment tax return for the 2025/26 tax year, the earliest valid lock date will be 6th April 2026 and the latest valid lock date will be based on the criteria above.

Similarly, if you have filed end-of-year accounts through FreeAgent and an automatic lock has been applied, the earliest valid lock date will be the beginning of the current accounting year. For example, if your accounting year ended on 31st December 2026 and you have filed end of year accounts, the earliest valid lock date will be 1st January 2027 and the latest valid lock date will be based on the criteria above.

Applying the manual lock

Once you have entered an appropriate date, select ‘Save Changes’. This will lock your accounts up to and including that date. The date will be displayed in your list of active account locks.

Changing a lock date

Update the date displayed in the ‘Add a manual account lock’ area and select ‘Save Changes’.

The new date will be displayed in your list of active account locks.

What happens when an account lock is in place

When there is an account lock in place, this prevents certain actions from being taken on your VAT returns, Self Assessment returns, bank transactions, invoices, payroll and opening balances.

VAT returns and settings

When there is an account lock in place, it’s not possible to file a VAT return or unlock a VAT return that has been marked as filed. You would need to remove the account lock to be able to perform either of these tasks.

If you register for VAT, you won’t be able to enter your VAT registration settings if there is an account lock in place for the period you’re registering from. For example, if you lock the accounts up to 31st October, you won’t be able to enter VAT registration settings during this period until you change the date of the account lock or remove it from your accounts.

Self Assessment returns

When there is an account lock in place, it’s not possible to file a Self Assessment tax return or unlock a return to make corrections. You would need to remove the account lock to be able to perform either of these tasks.

Please note that there won’t be an error message to indicate this, the buttons just won’t be visible.

Bank transactions

When there is an account lock in place, you can upload transactions from a bank statement or import them via a bank feed, but it’s not possible to explain any transactions which are unexplained. You would need to remove the account lock in order to explain them.

Invoices

When there is an account lock in place, you can create an invoice, but it’s not possible to mark it as sent or email it to a customer. You would need to either remove the account lock or change the invoice date to an open period.

Payroll

When there is an account lock in place, it’s not possible to submit payroll to HMRC. You would need to remove the account lock to be able to file the payroll.

Please note that there won’t be an error message to indicate this; the file button just won’t be visible.

Opening balances

When there is an account lock in place, it’s not possible to edit your opening balances. The opening bank balance(s) will be greyed out and there won’t be any error message. You would need to remove the account lock to be able to update your opening balances.
