If you've already filed your accounts with Companies House through TinyTax and need to correct them, you can submit amended accounts. This guide walks you through the process.

When You Need to Amend

You should amend your Companies House accounts if:

• You made a mistake in your original filing (wrong figures, missing items)
• You need to add balance sheet line items that were left out (e.g., fixed assets, long-term creditors)
• Your P&L figures need correcting

How to Amend Your Accounts

Step 1: Start the Amendment

1. Go to your TinyTax dashboard
2. Find the filing period you want to amend
3. Click Actions ▾ next to that period
4. Select Amend Accounts

Step 2: Enter Your Reason and Summary

A modal will ask you two questions:

• What was wrong with the original accounts? — Explain what needs correcting (e.g., "Turnover was understated by £5,000"). This appears in the revised accounts as required by Companies House.
• Summary of changes being made — Briefly describe your corrections (e.g., "Corrected turnover from £45,000 to £50,000").

Both fields are required. Click Proceed to Amendment to continue.

Step 3: Update Your Figures

The amendment opens the same full submission form as your original filing. All fields are available — you can:

• Change existing figures
• Add values to fields that were blank in the original (e.g., fixed assets, creditors falling due after more than one year)
• Import a trial balance or CSV if you prefer

Step 4: Review and Submit

1. Click Preview to review your amended accounts
2. You'll see an Accounts Amendment banner confirming this is a revised filing
3. Your reason and summary will appear in the generated accounts document as a "Revised Accounts Statement"
4. Click Submit Accounts and enter your Companies House authentication code
5. Your amended accounts are filed with Companies House

What Happens After You Submit

• The amended accounts replace your original filing on the Companies House public record
• The original accounts remain visible with a note that they have been superseded
• Companies House reviews the amendment manually, so processing takes longer than a standard filing
• You'll receive confirmation once the amended accounts are accepted

Common Questions

Can I amend accounts that were filed elsewhere?

No. The "Amend Accounts" option only appears for accounts originally filed through TinyTax. If your original accounts were filed through another service or via WebFiling, you'll need to use that service to submit the amendment.

Do I need to amend my CT600 as well?

It depends on what changed. If your amendments affect figures that also appear on your CT600 (like turnover or profit), you should amend your CT600 separately. See our CT600 amendment guide.

Is there a fee for amending accounts?

TinyTax doesn't charge extra for amendments — they're included with your subscription. Companies House doesn't charge a fee for revised accounts either.

Can I amend more than once?

Yes. If your amended accounts are accepted and you later find another error, you can submit a further amendment from the dashboard.
