Your quarterly updates, from the app you already run the job in.
Manifold connects to HMRC, keeps your income and expenses as digital records and sends the quarterly update for your self-employment. No second subscription, no exporting a spreadsheet to somebody else’s software four times a year.
Early access. HMRC production approval is still in progress. Annual tax return filing is not available in Manifold yet.
What Manifold does for your tax.
Connect to HMRC once
You sign in at HMRC's own site and grant Manifold access. Nothing of your Government Gateway sign-in ever passes through us, and you can disconnect from the Tax tab at any time.
Your businesses and deadlines, from HMRC
Manifold reads your self-employment businesses and your obligation periods directly from HMRC, so the four quarterly deadlines you see are the ones HMRC is actually holding you to, not a calendar we guessed.
Digital records that satisfy the rules
Keep income and expenses as a digital ledger: add a transaction as you go, or import a CSV from your bank with a dry-run preview before anything is written.
Categorising you can correct
Transactions are sorted into HMRC's self-employment categories with a review queue for anything uncertain. Amount, date and direction are frozen once recorded. The category is yours to change.
Mileage without the receipts
Simplified expenses are worked out at HMRC's approved mileage rates, with the 10,000-mile tier handled properly, so a van-heavy year does not need a shoebox.
Send the quarterly update
When a period is ready, Manifold submits the cumulative totals to HMRC and stores what was sent. You see what went, when, and for which period.
What is not in it yet.
Manifold is being built in stages, and you should know what you are getting before you rely on it for a tax deadline.
- Your annual tax return (the final declaration). Quarterly updates do not replace it. You need other compatible software or an accountant with compatible software to complete this step until Manifold supports it.
- An in-app estimate of the tax you will owe. Your figures go to HMRC. The estimate comes back from HMRC's own calculation, and that is a later piece of work.
- CIS deductions taken at source by contractors. It is next on the list because it matters to most subcontractors.
- Income appearing in the ledger automatically from your Manifold invoices. Today you add it or import it.
Not sure whether any of this applies to you yet? The free MTD readiness checker tells you which April you are caught by, from your own figures. Read HMRC’s guide to how Making Tax Digital works for the quarterly and annual requirements.
Making Tax Digital questions, answered straight.
What is Making Tax Digital for Income Tax?
Making Tax Digital requires people in scope to keep digital records and send quarterly summaries using compatible software. You still submit an annual tax return. The qualifying income thresholds for self-employment and property income combined are over £50,000 from April 2026, over £30,000 from April 2027, and over £20,000 from April 2028.
Does Manifold work for Making Tax Digital?
Manifold connects to HMRC, keeps your digital records and sends your quarterly updates for self-employment income. It is in early access while HMRC's production approval process for MTD for Income Tax is open, so if you want to be on it from your first quarter, get on the list now.
Who can use the Tax tab?
Sole traders. MTD for Income Tax is a personal tax assessed on your National Insurance number, so a limited company is never in scope for it and the tab does not appear for one. If you trade as a limited company you carry on with Corporation Tax as normal.
Do I need separate bookkeeping software as well?
Manifold covers digital records and quarterly updates for self-employment. Annual tax return filing is not available in Manifold yet, so you need other compatible software or an accountant with compatible software for that step. Property income and partnerships are not supported here.
What does it cost?
The Tax tab is part of Manifold, priced from £15 per engineer per month with a 30-day free trial and no card needed. There is no separate charge for filing.
I am not a gas engineer. Can I still use it?
Manifold is built around gas and heating work, so most of it will not earn its keep for you. We make a second product, QTRLY, which does the Making Tax Digital side and nothing else, for sole traders and landlords generally. Both are made by Easy Insight Limited.
Manifold is made by Easy Insight Limited, a UK company. When you connect to HMRC you will see that company name on HMRC’s own permission screen, because that is who holds the software registration. See how we handle your data or what Manifold costs.
