The four options on the Start Filing menu refer to different combinations of what gets submitted and where:
**CT600 and Accounts** — TinyTax files both at once:
- CT600 (corporation tax return) → sent to HMRC
- Annual accounts → sent to Companies House
This is the standard option for most active limited companies that need to meet both obligations for the same period in one go.
**CT600 only** — TinyTax files just the corporation tax return to HMRC. Use this when your Companies House accounts have already been filed separately (for example by an accountant or through another service), or if your company is not required to file accounts with Companies House for that period.
**Accounts only** — TinyTax files just your annual accounts to Companies House. Use this if you have already submitted your CT600 to HMRC through another route and only need to sort out the Companies House side.
**CT600 filed elsewhere** — This is not a filing itself. It is a way to tell TinyTax that you submitted a prior year's CT600 outside TinyTax (for example directly via HMRC, or through other software). Marking a period as filed elsewhere lets you move on to filing the current year — TinyTax requires periods to be filed in order, so an earlier unfiled period would otherwise block the current one.
One note: "CT600 filed elsewhere" only applies to CT600. Companies House accounts are automatically detected from the public register, so there is no equivalent option for accounts — TinyTax picks those up automatically.
