What can DIY Accounting Submit file for me?
DIY Accounting Submit files VAT returns with HMRC under Making Tax Digital. It also files micro-entity, small company and dormant company accounts and the confirmation statement with Companies House. It does not file Income Tax updates or a Company Tax Return for customers today.
What Submit files today
- VAT returns from a spreadsheet, sent to HMRC under Making Tax Digital for VAT
- Micro-entity accounts, filed with Companies House
- Small company accounts, filed with Companies House
- Dormant company accounts, filed with Companies House
- The confirmation statement, filed with Companies House
The Self Employed and Company Accounts spreadsheets total the nine VAT boxes. You copy those figures into Submit and send them.
Company accounts and the confirmation statement
The Company Accounts workbook has a published profit and loss account, a published balance sheet and published notes in the statutory format. The package guide says a named director must sign the balance sheet before it is submitted. Submit files the accounts and the confirmation statement.
Income Tax and Self Assessment
Making Tax Digital for Income Tax applies to qualifying income over £50,000 from 6 April 2026, over £30,000 from 6 April 2027 and over £20,000 from 6 April 2028.[1] Those taxpayers send quarterly updates with software HMRC accepts.
Submit does not send those updates for customers today. Until it does, use software from HMRC's own software finder. HMRC describes bridging software as software that connects to existing records kept in spreadsheets or other accounting tools.[2] The Self Employed workbook prepares the figures. Read what a cumulative quarterly update is to see how to total them.
The Company Tax Return
HMRC's online service for company accounts and the Company Tax Return closed on 31 March 2026. From 1 April 2026 a company uses commercial software to file them.[3] A company can file a paper return only if it has a reasonable excuse or wants to file in Welsh.[4]
Submit does not file the Company Tax Return for customers today, so a company needs other commercial software for that return. The deadline is 12 months after the end of the accounting period the return covers.[5] The Company Accounts workbook prepares the profit, the capital allowances and the corporation tax figures that go into the return. See tax accounting software and the company tax return.
