The "personal code" you need depends on what you're filing:

**Confirmation Statement (CS01) or Annual Accounts — Companies House authentication code**

This is a 6-character alphanumeric code that Companies House posted to your company's registered office address when the company was first registered. You enter it in TinyTax when submitting accounts or a confirmation statement.

If you don't have it:
1. Go to gov.uk/file-your-company-annual-accounts
2. Click "Request an authentication code"
3. Enter your company number and confirm your registered office address
4. A new code arrives by post within 5 working days

**CT600 to HMRC — Government Gateway User ID**

If you're filing your Corporation Tax return, the code you need is your 12-digit Government Gateway User ID plus your password. Log in at gov.uk/log-in-register-hmrc-online-services to find it.

For more detail on both codes, see:

Let me know if you're stuck on a particular step and I'll help from there.
