The four filings
Bookkeeping at the centre, four filings around it. Each one says where it stands with HMRC today.




What is inside
Keep your records once. Reports and the VAT return build from the same ledger.
Capture
Upload photos, PDFs or spreadsheets. AI reads each one and suggests a category. You confirm or change it.

Control
A quarterly update cannot be sent while a transaction in that period is unconfirmed. Auto-approve and automatic payroll submission are optional and stay off until you turn them on.

Security
National Insurance numbers and HMRC tokens use AES-256-GCM.
Reports
Illustrative · demo data
Export
CSV files for the packages below, and PDF of the trial balance, profit and loss and balance sheet. Files only: there is no link to these vendors.
Practices
How it works
Upload receipts, invoices and bank statements.
AI reads each document and suggests a category. You confirm or change it. A quarterly update cannot be sent while a transaction in that period is unconfirmed.
TiraTax prepares the return from your records. You check each figure and confirm before a return is sent. For customers, submission runs against HMRC's test service today.
See it work
Each recording ends with HMRC's test service accepting the submission. The data in them is test data.
A sole trader checks the quarter, runs the readiness checks and submits the second quarterly update. HMRC's test service accepts it.
The app connects to HMRC's sandbox through HMRC's own permission page, calculates a VAT return and submits it to HMRC's test service after the declaration. The test service accepts it and the app shows the receipt.
A limited company completes the accounts facts, previews the iXBRL accounts and the computation, runs the pre-flight checks and submits. HMRC's test service accepts the return. Customers cannot file a Corporation Tax return today.
Two test employees are paid in a pay run. The Full Payment Submission is built and sent, and HMRC's test service accepts it.
Recorded in HMRC's sandbox, which is HMRC's test service, with test data. The app's sidebar still shows its earlier name, Tiraverse MTD. The MTD ITSA Income Tax clip runs on a set date and the VAT clip uses HMRC's 2017 test quarter.

Security
Each one is in the app today.
National Insurance numbers, HMRC tokens, Gateway credentials and two-step secrets are encrypted inside the application.
Authenticator codes with recovery codes. Optional for each person, and required when an organisation sets that policy.
Many actions are written to an append-only log. The application has no way to edit or delete an entry.
A quarterly update cannot be sent while a transaction in that period is unconfirmed. Automatic payroll submission is optional and off until you turn it on.

Questions
What TiraTax does today, and what it does not do yet.
Not yet. TiraTax is in early access by invitation. Request access and we will reply by e-mail.
Not yet. TiraTax is completing HMRC's recognition process. We only describe software as HMRC recognised once that recognition is granted.
Not for customers yet. MTD ITSA Income Tax, VAT and payroll run against HMRC's test service for customers, and Corporation Tax (CT600) filing is switched off. We will say here when that changes.
Yes, to read documents and suggest categories. Document images, spreadsheet contents, bank statement lines and transaction details are sent to AI providers to do this. A quarterly update cannot be sent while a transaction in that period is unconfirmed. Auto-approve is optional and stays off unless you turn it on.
