Receipts in, categories suggested, figures for you to confirm: for sole traders, landlords, limited companies and accountancy practices.
From April 2026, sole traders and landlords earning over £50,000 must send HMRC quarterly updates; the threshold drops to £30,000 in 2027 and £20,000 in 2028. HMRC’s free Company Accounts and Tax Online (CATO) portal closed permanently on 31 March 2026: the annual CT600 and its iXBRL format did not change, but the free way to file it went.
| Option | What it leaves you with |
|---|---|
| Full accounting suites: Xero, QuickBooks, Sage | Built for inventory, project tracking and multi-currency; £20–£65 a month for features you will never use, and payroll is often a paid add-on. |
| Bridging tools | They meet the MTD requirement, but the bookkeeping stays yours: your own spreadsheet, every transaction categorised by hand. |
TiraTax is built for the work in between: from a pile of receipts to a finished return, with the least effort.
Photograph a receipt, forward an invoice by email or drop in a bank statement (photos, PDFs, Excel or CSV), even from your phone. Each line item (supplier, date, amounts, VAT) is extracted, built in rather than a paid add-on, and the HMRC category is suggested for you to approve.
Double-entry bookkeeping with trial balance, profit and loss and bank statement matching, kept up to date as you upload. No spreadsheets or accountancy knowledge needed: leave the processing to us and follow the detailed reports, or review every line yourself.
MTD quarterly updates for self-employment, UK property and foreign property, so landlords and sole traders use one tool. Annual submission, HMRC’s tax calculation, final declaration and amendments, each with a confirmation and a full audit trail.
MTD VAT returns: all nine boxes calculated from your transactions and checked against the ledger.
The CT600 with the tax computation and iXBRL accounts, plus a PDF copy for your records; CT600 filing is switched off for live use. Past CATO filings, three years or more, can be uploaded and kept searchable.
Sole-trade or property income above £50,000 outside the company means MTD Income Tax as well as the CT600; salary and dividends from the company do not count. Both are in one app, with payroll and directors’ NI when you pay yourself.
Auto-Pilot sends clients deadline reminders on your schedule, and the receipts and invoices they email back become categorised transactions and kept books: less chasing, less manual entry, no separate accountancy software. One dashboard shows every client’s deadlines, who has submitted and who is overdue, and runs their returns and payroll. Client data is hosted in the UK.
Screen recordings of TiraTax sending test data to HMRC’s sandbox, the test environment HMRC provides to software developers. Sign-in and permission steps happen on HMRC’s own GOV.UK pages, and the responses come back from HMRC’s sandbox. Recorded on 25 and 26 August 2026 with HMRC-issued test credentials, under the product’s earlier name; no real taxpayer data appears.

Books to boxes: the return is calculated from the transactions, checked against the ledger and submitted after an explicit declaration. It starts with connecting to HMRC on GOV.UK pages and ends with HMRC’s sandbox accepting the test data.

HMRC publishes the software features and income sources that MTD for Income Tax software can support. TiraTax implements all 10 features, all 3 business types (self-employment, UK property and foreign property) and 15 of the 16 income sources, each with its own form and validation. It works with 17 HMRC APIs and more than 60 endpoints; Tiraverse is completing HMRC’s recognition process.

A PAYE payroll module for the 2026-27 tax year: employees, payslips, statutory pay, pensions and RTI, in the app that prepares your Income Tax, VAT and CT600. Practices can run it for their clients from the same dashboard. RTI submissions go to HMRC’s sandbox today.
PAYE, National Insurance and student loans to the penny, verified against HMRC’s own test data: all standard tax codes with Scottish and Welsh rates, 17 NI category letters (freeport, investment zone, veteran and apprentice rates included) and directors’ NI on the annual method.
A Full Payment Submission for every pay run, tracked through to acceptance; Employer Payment Summaries for Employment Allowance, statutory recoveries and no-payment periods. A rejection shows HMRC’s own message, and you rebuild a corrected submission.
Approve a run and each employee receives a PDF payslip by email (earnings, deductions, year-to-date figures) with National Insurance numbers and bank details masked, plus a summary of what to pay each person.
Statutory sick pay under the reformed April 2026 rules; maternity, paternity, adoption, shared parental, bereavement and neonatal care pay, with employer recovery and Small Employers’ Relief. Auto-enrolment assessed on every run, opt-outs and postponement handled, and a PAPDIS file for your pension provider.
A working-hours register checks pay against each employee’s National Minimum Wage band and flags young-worker working-time limits. Employment contracts and written statements of particulars from the data you hold, with a sequential contract register and right-to-work records.
Approving a run posts a balanced journal to your chart of accounts; the P32 record shows what you owe HMRC each month, Employment Allowance included. Starter declarations, opening balances for mid-year switches, and P45 and P60 data for leavers and year end.
An email before each Full Payment Submission is due, and a flag on overdue or missing runs. Optional automatic filing sends approved runs to HMRC’s sandbox on payday today, under a strict rule: it only files what it prepared itself and never silently retries a rejection.
TiraTax is built and hosted in the UK by a UK-registered company, and your records are stored on UK servers. To read receipts and invoices, documents are sent to outside document-reading services, such as Google Cloud’s Document AI and Anthropic’s API.
Early-access prices in GBP. No VAT is added: Tiraverse Ltd is not VAT-registered. Early-access pricing holds while HMRC’s recognition process completes.
Status: early access by invitation. Every filing runs against HMRC’s test service (sandbox) or is switched off; CT600 filing is switched off for live use. The recordings above end with HMRC’s sandbox accepting test data.
