Making Tax Digital — without the compromise
From receipt to HMRC submission
Upload your invoices and bank statements — even from your phone. We handle the rest: processing, bookkeeping, HMRC quarterly reporting, VAT — and now PAYE payroll. No spreadsheets, no accountant fees, no accountancy knowledge needed.
And from 1 April 2026, every limited company needs commercial CT600 filing software — HMRC is shutting down its free portal permanently. We handle that too.
The problem
MTD software tends to fall into two frustrating camps
From April 2026, sole traders and landlords earning over £50,000 must submit quarterly digital returns to HMRC. That threshold drops to £30,000 in 2027 and £20,000 in 2028. You need software to do it.
Your choices today are not great.
Option A: Full accounting suites
Xero, QuickBooks, Sage. Powerful, but built for businesses with inventory, project tracking, and multi-currency needs. You pay £20–£65/month for features you will never use — and payroll is often a paid add-on on top.
Option B: Bridging tools
Bridging tools. They technically satisfy the MTD requirement, but the bookkeeping stays yours: you maintain your own spreadsheet, categorise every transaction by hand, and push a button to submit. The work does not go away.
Both options share the same flaw: one overcharges you for features you do not need, the other leaves all the actual work to you. Neither solves the real problem: getting from a pile of receipts to a submitted return with the least possible effort.
And if you run a limited company?
HMRC’s free Company Accounts and Tax Online (CATO) portal closes permanently on 31 March 2026. The filing itself does not change — annual CT600, same iXBRL format — but your free submission channel vanishes. You need a separate product for your company, and another for your personal tax if you have qualifying income. Tiraverse handles both — the company CT600 and your personal ITSA.
Why Tiraverse TAX
Three things Tiraverse TAX is built to do
From upload to submission
Upload a photo of a receipt. We extract every line item — supplier, date, amounts, VAT — and suggest the correct HMRC category. You review and approve. One click to submit to HMRC.
Tiraverse handles the full pipeline — from photo to HMRC submission — in one product. Bridging software skips the extraction entirely. Receipt and invoice extraction is built in — not a paid add-on. Tiraverse TAX does it natively, from upload to submission.
Your data stays in the UK
Your financial data is hosted in the UK, on UK servers. No US-owned cloud platforms. No third-party data centres you cannot audit.
QuickBooks is US-owned (Intuit). Xero is New Zealand-based. Tiraverse is UK-registered and UK-hosted. Tiraverse TAX is built and hosted entirely in the UK.
ITSA + CT600 + VAT + Payroll — without the bloat
Quarterly ITSA for self-employment and property income. Annual CT600 for your limited company. MTD VAT returns. PAYE payroll when you take on staff. One platform, no extra cost for the company filing — without paying for inventory or project management you will never touch.
Tiraverse handles both personal ITSA and company CT600 in one product. If you are a director with qualifying self-employment or rental income, that means one product instead of two — and if your company pays staff, payroll is already in it.
Proof, not promises
Watch real submissions reach HMRC
Screen recordings of Tiraverse TAX filing to HMRC's sandbox — the official test environment HMRC provides to software developers, running the same build as production. The sign-in and permission steps happen on HMRC's own GOV.UK pages, and the acceptance responses come back from HMRC's systems. The VAT and Income Tax recordings are unedited; the Corporation Tax and payroll recordings trim only HMRC's few-minute processing wait, marked by a caption.
MTD VAT return, end to end
Books to boxes: the return is calculated from transactions, checked against the ledger, submitted after an explicit declaration — and HMRC's receipt comes back.
MTD Income Tax quarterly update
A quarter's bookkeeping reviewed, readiness checks passed, and the quarterly update submitted to HMRC after an explicit confirmation.
CT600 Corporation Tax return, filed electronically
A limited company's year: statutory accounts facts, iXBRL accounts and computation generated and validated, the return filed after an explicit confirmation — and HMRC's acceptance comes back. Only HMRC's two-minute processing wait is trimmed.
PAYE payroll: pay run to accepted FPS
A monthly pay run calculated and approved, payslips produced, the Full Payment Submission built and sent after an explicit confirmation — and HMRC's acceptance comes back with its correlation ID. Only the few-minute wait is trimmed.
Recorded 25–26 August 2026 against HMRC's sandbox environment using HMRC-issued test credentials. No real taxpayer data appears in these recordings.
How it works
Three steps. No spreadsheets.
Upload
Take a photo of a receipt on your phone, forward an invoice by email, or drop a bank statement into the app. Photos, PDFs, Excel, CSV — any format works. You do not even need a computer.
We process
We extract every line item, match each transaction to the correct HMRC category, and maintain your books. You can review everything in full detail at any time — or leave it to us entirely.
We report
Quarterly ITSA updates, VAT returns, annual submission, final declaration — all submitted to HMRC on your behalf. You get a confirmation and a full audit trail for every submission.

How it works for you
Everything MTD requires. Nothing it doesn't.
For sole traders & landlords
Two ways to use Tiraverse TAX — choose the one that suits you:
We handle it for you
Upload your invoices and bank statements — from your phone, email, or computer. We take care of everything else: document processing, bookkeeping, HMRC quarterly reporting, VAT returns, annual submission, and final declaration. You get full transparency with detailed reports at every step. No spreadsheets. No accountant fees. No accountancy knowledge needed.
Or do it yourself
Prefer to stay in control? Upload your documents, review the extracted data, approve the HMRC categories, and submit directly to HMRC yourself. The same tools, with you at the wheel.
Both options include
Document extraction — upload a photo, PDF, or spreadsheet and we extract every line item
Complete bookkeeping — income, expenses, and running totals maintained as you upload
ITSA quarterly updates — self-employment, UK property, and foreign property submitted to HMRC
Full tax return — report all 15 additional income sources directly to HMRC
MTD VAT returns — all nine boxes prepared and submitted directly
Annual submission & final declaration — year-end adjustments and HMRC tax calculation
Amendments — amend quarterly and annual updates after submission
CSV & spreadsheet import — bridging software for bank statements and existing records
For accountancy practices
Everything sole traders get, plus tools built specifically for managing multiple clients. No separate accountancy software needed.
Auto-Pilot
Tiraverse TAX sends deadline reminders to your clients. Clients reply by email with their receipts and invoices attached. Those attachments are extracted, converted into categorised transactions, and the bookkeeping is done — no chasing, no manual data entry on your side.
Raw data to bookkeeping
Documents arrive from client emails as raw data — photos of receipts, scanned invoices, bank statements. Tiraverse TAX extracts the data, creates the transactions, and maintains the books. Complete bookkeeping directly from raw source documents, with no manual processing step.
Client management dashboard
See all your clients in one place. Track obligation deadlines, see who has submitted and who is overdue, and file on their behalf — returns and client payroll alike. No spreadsheet of client statuses needed.
Automated client communication
Deadline approaching? Tiraverse TAX notifies your clients at the right time, with the right message. You set the schedule once and let the system handle the follow-ups.
CT600 Corporation Tax
CATO closes. Tiraverse replaces it.
HMRC’s free Company Accounts & Tax Online portal shuts down permanently on 31 March 2026. Every limited company needs commercial software from 1 April. The filing itself does not change — same annual CT600, same iXBRL format. Only the free channel disappears.
CT600 + iXBRL output
Full Corporation Tax computation with compliant iXBRL accounts and tax computation. Direct submission to HMRC via Government Gateway. PDF export for your records.
Historic Filing Rescue
Upload and archive your CATO filings before HMRC wipes access. Three or more years of historic returns, preserved and searchable in your Tiraverse account.
Director crossover
Directors with qualifying self-employment or rental income above £50,000 need both ITSA and CT600. Salary and dividends from your own company do not count toward the ITSA threshold — only separate sole-trade or property income does. One platform handles both.
For accountancy practices — a client acquisition opportunity
Displaced micro-entity self-filers who used CATO for free now need professional help. These are new clients for your firm. Tiraverse helps you onboard them with CT600 annual filing and ITSA quarterly reporting from a single dashboard — Auto-Pilot handles the document collection, and your team reviews and submits. One login, both April 2026 deadlines handled.
New — PAYE Payroll
Pay your team. File as you go.
Tiraverse TAX now includes a PAYE payroll module for the 2026-27 tax year. The platform that files your ITSA, VAT and CT600 also runs your payroll — employees, payslips, statutory pay, pensions and RTI submissions to HMRC — and accountancy practices can run it for their clients from the same dashboard.
PAYE and NI proven against HMRC data
PAYE, National Insurance and student loans calculated to the penny and verified against HMRC’s own test data. All standard tax codes including Scottish and Welsh rates, 17 NI category letters — freeport, investment-zone, veteran and apprentice rates included — and directors’ NI on the annual method.
RTI filed direct with HMRC
Every pay run produces a Full Payment Submission, filed with HMRC and tracked through to acceptance. Employer Payment Summaries cover Employment Allowance, statutory recoveries and no-payment periods. If HMRC rejects a filing, you see HMRC’s own message and rebuild a corrected submission.
Payslips straight to your team
Approve a run and every employee receives a PDF payslip by email — earnings, deductions and year-to-date figures, with National Insurance numbers and bank details masked. A per-run payment summary shows exactly what to pay each person.
Statutory pay and pensions
Statutory sick pay under the reformed April 2026 rules, plus maternity, paternity, adoption, shared parental, bereavement and neonatal care pay — with employer recovery and Small Employers’ Relief worked out. Auto-enrolment assessment on every run, opt-outs and postponement handled, and a PAPDIS file ready for your pension provider.
Hours, minimum wage and contracts
A working-hours register checks pay against the National Minimum Wage band for each employee’s age and flags young-worker working-time limits. Generate UK employment contracts and written statements of particulars from the data you already hold, with a sequential contract register and right-to-work records.
Wired into your books and your year
Approving a run posts a balanced journal straight into your chart of accounts, and the P32 employer payment record shows what you owe HMRC each month, Employment Allowance included. Starter declarations, opening balances for mid-year switches, and P45 and P60 data ready for leavers and year end.
Deadlines that come to you
Tiraverse TAX emails you before each Full Payment Submission falls due and flags overdue or missing runs, so on-or-before filing does not depend on memory. And if you would rather not press the button at all, optional automatic filing submits approved runs to HMRC on payday — governed by a strict rule that it only ever files what it prepared itself, and never silently retries a rejection.

Who it's for
Built for the people who actually file
Sole traders
Self-employed individuals earning over £50,000 who must file under MTD from April 2026. The threshold drops to £30,000 in 2027 and £20,000 in 2028. Upload your documents — even from your phone — and we handle the bookkeeping, quarterly reporting, and VAT.
Landlords
UK property landlords with qualifying rental income. Submit property income quarterly alongside any self-employment income — in the same tool, not two separate products.
Limited company directors
HMRC’s free CATO portal closes 31 March 2026. You need commercial software for your annual CT600. And if you have qualifying income above £50,000 outside your company, you need ITSA too. Director salary and dividends do not count toward the threshold — only separate sole-trade or property income does. When you pay yourself a salary, payroll — including directors’ NI — is built in.
Accountancy practices
Auto-Pilot collects raw data from your clients by email and turns it into categorised transactions with complete bookkeeping. Sole traders, landlords, limited companies (CT600), and client payroll all managed from one dashboard. All client data hosted in the UK.
Both April 2026 deadlines handled
