How to Keep Digital Records for MTD (Income Tax): A Step-by-Step Workflow for 2026–2028

Making Tax Digital (MTD) for Income Tax Self Assessment (ITSA) is changing how self-employed people and landlords keep records and report income tax. The biggest practical shift is this: you’ll need digital records and you’ll send quarterly updates to HMRC using MTD-compatible software.

This guide gives you a calm, step-by-step workflow you can follow month-by-month. It’s written for real life: messy inboxes, paper receipts in the van, multiple bank accounts, and the occasional “I’ll sort it later”. If you build a simple routine now, MTD becomes a manageable admin habit rather than a last-minute panic.

MTD for Income Tax: who it affects, and when (2026–2028)

MTD for Income Tax is being introduced in stages, based on your qualifying income (broadly, income from self-employment and/or property). The current rollout timetable is:

If you’re close to a threshold, it’s still worth preparing early. Good digital records help even before MTD starts — and they reduce the cost and stress of year-end accounts.

What HMRC means by “digital records” (plain English)

For MTD for Income Tax, keeping digital records doesn’t just mean “I have PDFs somewhere”. In practice, it means:

• Your income and expenses are recorded in software (or in a spreadsheet that is digitally linked to MTD bridging software).
• Each entry has key details (date, amount, category, and who it was from/to).
• Updates are sent to HMRC quarterly from that digital record, via MTD-compatible software.
• Digital links are used where data moves between systems (for example, an import, a connected app, or a bridging tool — not copy-and-paste).

The goal is consistency: you keep records as you go, and the quarterly updates become a straightforward by-product of tidy bookkeeping.

The step-by-step workflow: keep digital records without it taking over your life

Below is a practical workflow we recommend at Tax Digital. It works whether you have one income stream or several, and whether you’re meticulous or more “get it done at the weekend”.

Step 1: Choose your record-keeping method (software vs spreadsheet)

You have two main routes:

If you already use spreadsheets and they work well, you may not need to abandon them — but you will need a clean process, and you’ll need to be comfortable maintaining it regularly.

Step 2: Set up a simple digital filing structure (so you can find things later)

Even with good software, you’ll still have documents: invoices, receipts, loan statements, tenancy agreements, mileage logs, and so on. A tidy folder structure saves hours at year end.

Use a cloud folder (for example, in your preferred storage service) and keep it consistent:

Tax Year 2026-27/
  Income/
    Sales Invoices/
    Other Income/
  Expenses/
    Advertising & Marketing/
    Motor & Travel/
    Tools & Equipment/
    Office & Admin/
    Phone & Internet/
    Rent, Rates & Utilities/
    Professional Fees/
  Bank & Card Statements/
  Payroll (if any)/
  Property (if any)/
  VAT (if registered)/
  Year-End/

Keep file names predictable. For example: 2026-05-14_Screwfix_£38.50_Receipt.pdf or 2026-06_ClientName_Invoice_104.pdf.

Step 3: Separate business and personal money (it makes MTD far easier)

If you do one thing to make MTD easier, do this: use a separate business bank account (and ideally a separate business card).

It’s not a legal requirement for sole traders, but it is one of the biggest time-savers. It means:

• Bank feeds are cleaner
• Fewer “what was this payment for?” moments
• Less chance of missing expenses
• Quarterly updates are quicker and more accurate

Step 4: Decide your “capture habit” for receipts and invoices

MTD record-keeping works best when you stop relying on memory. Choose one habit and stick to it:

Step 5: Set up your chart of categories (keep it simple and consistent)

MTD doesn’t require you to become an accountant — but you do need expenses recorded in sensible categories. The trick is to keep categories stable, so quarterly updates are consistent.

Common categories for self-employed people and landlords include:

• Income (sales/fees; other income)
• Motor & travel (fuel, parking, public transport, mileage logs)
• Tools & equipment (small tools; larger equipment may be treated differently)
• Phone & internet
• Office/admin (stationery, postage, software subscriptions)
• Advertising/marketing
• Professional fees (accountancy, legal)
• Use of home (if applicable)
• Property expenses (repairs, letting agent fees, insurance, utilities if paid by landlord)

If something doesn’t fit, don’t create dozens of new categories. Use a sensible “general” category and add a note. We can tidy the detail at year end if needed — the key is that the record is complete and supported.

Step 6: Build your “digital evidence” habit (what to keep and why)

For each income or expense, you should be able to answer two questions:

1. What was it for? (business purpose)
2. Can you evidence it? (receipt, invoice, statement, contract, mileage log)

Good evidence means fewer queries later, and it protects you if HMRC ever asks for backup.

Step 7: Reconcile little and often (this is where accuracy comes from)

Reconciling simply means checking that what’s in your software matches your bank and card activity, and that you’ve not missed anything.

A sensible routine is:

• Weekly (10 minutes): review new bank feed items and categorise them
• Monthly (30–60 minutes): chase missing receipts/invoices; check any unusual payments; ensure cash transactions are recorded
• Quarterly (60–90 minutes): do a deeper check before submitting your MTD update

Most MTD problems come from leaving everything until the quarter end, then trying to remember what happened three months ago.

Step 8: Deal with “mixed” transactions properly (personal and business together)

Mixed transactions are common — and they’re a frequent source of mistakes. Typical examples include:

• A phone bill used partly for business
• A vehicle used for both business and personal journeys
• Home broadband used for work and personal use
• Purchases where only some items are business-related

In your records, you’ll usually need to claim only the business portion. The best approach is to pick a reasonable method and apply it consistently, keeping a note of how you worked it out.

Step 9: Prepare for quarterly updates (what you need ready before you submit)

Each quarter, your software will send a summary of income and expenses to HMRC. Before you press submit, do this quick check:

If you’re not sure whether something is allowable, don’t ignore it. Record it, add a note, and ask your accountant. It’s much easier to adjust properly than to guess or leave gaps.

Step 10: Understand the year-end steps (MTD doesn’t remove the “tax return” work)

Under MTD for Income Tax, you still have year-end tasks. The names change slightly, but the principle is familiar:

• Quarterly updates: summaries during the year
• Year-end finalisation (EOPS): confirm final business/property figures and apply accounting/tax adjustments
• Final declaration: confirm all taxable income (including anything outside the business records) and submit the final position

So, while MTD spreads the admin through the year, it doesn’t remove the need to review the numbers properly at the end.

A practical quarterly workflow you can copy (with dates)

To stay calm under MTD, aim for a repeating routine. Here is a simple pattern:

Common digital record-keeping mistakes (and how to avoid them)

What this means for landlords (a quick note)

If you’re a landlord, your “digital records” typically include:

• Rental income by property and by date received
• Letting agent statements and fees
• Repairs and maintenance invoices
• Insurance and compliance certificates (where relevant)
• Mortgage interest statements (where applicable)

Landlord records can be straightforward — but they can also get complicated quickly if you have multiple properties, joint ownership, or periods of voids. The earlier you set up a consistent system, the less stress you’ll have when quarterly updates begin.

A simple “MTD-ready” toolkit (what to set up now)

You don’t need a complicated tech stack. Most people only need:

• MTD-compatible bookkeeping software (or a spreadsheet plus bridging software)
• A cloud folder structure for supporting documents
• A receipt capture method (mobile app or email forwarding rule)
• A weekly diary slot to keep records current

If you’d like, we can help you choose the simplest setup for your situation and make sure it meets HMRC’s MTD rules without adding unnecessary admin.
