Everything you need for MTD ITSA

Tiraverse covers every feature on the HMRC recognised software listing — record keeping, bridging, submissions, amendments, and final declaration.

Instant OCR Extraction

Upload a receipt or invoice and we extract every line item automatically.

Automated Categorisation

Expenses and income are automatically mapped to the correct HMRC categories with confidence scoring.

Bridging Software

Import transactions from bank CSV exports or Excel spreadsheets. Auto-detect columns, dates, and amounts.

Quarterly Submissions

Submit quarterly updates directly to HMRC. Cumulative submission for 2025-26 onwards with automatic period calculation.

Amend Anytime

Amend quarterly updates and annual submissions after filing. Full amendment history tracked.

Tax Calculation & Final Declaration

View your HMRC tax calculation, submit annual adjustments, and file your final declaration — all from one place.

View Submitted Updates

Review all submitted quarterly updates, annual submissions, and tax return entries with timestamps and HMRC references.

Reduce Payments on Account

Submit and amend coding out requests to HMRC to reduce your payments on account.

Full Tax Return

Report all 15 additional income sources — interest, dividends, pensions, capital gains, employments, foreign income, and more.

Every business type supported

Manage multiple businesses from a single account. Each with its own HMRC submissions, categories, and tax periods.

Self-Employment

Sole traders with cumulative quarterly submissions, capital allowances, and trading income allowance.

UK Property

Rental income, mortgage interest, repairs, and all property expense categories.

Foreign Property

Overseas rental income with foreign tax credit, 8 expense categories, and country-specific reporting.

Limited Company

Annual CT600 Corporation Tax filing with iXBRL output and direct submission via Government Gateway.

31 March 2026

HMRC is shutting down free CT600 filing

Company Accounts & Tax Online (CATO) closes permanently on 31 March 2026. Every limited company will need commercial software to file CT600 returns. The filing itself does not change — annual CT600, same iXBRL format — only the free submission channel disappears.

CT600 + iXBRL output

Full Corporation Tax computation with compliant iXBRL accounts and tax computation. Direct submission to HMRC via Government Gateway.

Historic Filing Rescue

Upload and archive your CATO filings before HMRC wipes access. Three or more years of historic returns, preserved and searchable.

Director crossover

Directors with qualifying self-employment or rental income above £50,000 need both ITSA and CT600. One platform handles personal and company filing.

For accountancy practices

Displaced micro-entity self-filers who used CATO for free now need professional help. Tiraverse helps you acquire and serve these new limited company clients — CT600 annual filing and ITSA quarterly reporting from a single dashboard, with Auto-Pilot handling the document collection.

Complete HMRC software listing coverage

Tiraverse covers every software feature and nearly every income source on the HMRC recognised software listing — more than any other MTD ITSA provider.
