Making Tax Digital for Income Tax Self Assessment (MTD ITSA) requires qualifying UK sole traders and landlords to maintain digital records, submit quarterly updates, and file annual tax returns using HMRC-compatible software. This making tax digital requirements checklist walks you through every step you need to take before April 2026, covering eligibility thresholds, software selection, quarterly deadlines, exemptions, and year-end filing. Whether you earn above £50,000 or are planning ahead for the 2027 and 2028 thresholds, this guide gives you a clear, calm path through the process.
1. Making Tax Digital requirements checklist: where to start
Before you do anything else, you need to understand what MTD ITSA actually demands of you. MTD ITSA mandates creating, storing, and correcting digital records, sending quarterly updates to HMRC, and submitting your final tax return digitally using compatible software. This is not simply a digital version of your old Self Assessment return. It is a fundamentally different way of managing your tax obligations throughout the year.
The tax digitalization process spreads your admin across four quarterly updates plus a year-end submission, rather than one large annual return. MTD ITSA aims to distribute this workload throughout the year, which means smaller, more manageable tasks rather than a January panic. For sole traders and landlords who currently dread the Self Assessment deadline, this shift can genuinely reduce stress if you set things up correctly from the start.
2. Checking your eligibility and start date
The first practical step in any MTD compliance checklist is confirming whether you are in scope and when your obligations begin.
- From 6 April 2026, sole traders and landlords with qualifying income over £50,000 must comply with MTD ITSA.
- The threshold drops to £30,000 from April 2027.
- It drops again to £20,000 from April 2028.
- Qualifying income means your gross self-employment and property income combined, not your profit after expenses.
- If you have both a sole trader business and rental income, HMRC adds these together to assess your threshold.
- HMRC uses your tax returns to identify who must comply and will notify you directly, but you should not wait for that letter.
Understanding the qualifying income definition is critical. A sole trader earning £35,000 from their business and £20,000 from a rental property has qualifying income of £55,000, placing them firmly in the April 2026 cohort. Many people assume the threshold applies only to profit, which is incorrect. Gross income is the measure.
Pro Tip: If you use an accountant or bookkeeper, agents can sign up clients on their behalf ahead of the mandation date. Do not leave this until March 2026. Early sign-up avoids last-minute complications and gives you time to test your software before the first quarterly deadline.

3. Choosing compatible software and setting up digital records
Once you know you are in scope, selecting the right software is the most consequential decision you will make. MTD ITSA requires software compatible with HMRC digital systems, capable of storing digital records and submitting both quarterly updates and the final return.
The three most widely used options for sole traders and landlords are Xero, FreeAgent, and QuickBooks. Each connects directly to HMRC’s systems and supports the full MTD ITSA workflow. Here is what to look for when choosing:
- HMRC recognition. Confirm the software appears on HMRC’s list of compatible products. Xero, FreeAgent, and QuickBooks all qualify.
- Quarterly update submission. The software must send your income and expense summaries directly to HMRC each quarter.
- Calendar quarter election support. Some software allows you to elect calendar quarters (January to March, etc.) rather than tax-year quarters. Check this before committing.
- Bank feed integration. Automatic bank feeds pull transactions directly into your records, reducing manual entry and errors.
- Landlord or sole trader categorisation. Property income and self-employment income are reported separately under MTD ITSA. Your software must handle both if you have both income types.
- Cost and support. Xero starts from around £16 per month for sole traders. FreeAgent is free with certain business bank accounts, including NatWest and Royal Bank of Scotland. QuickBooks offers a self-employed tier suited to simpler needs.
Digital records must be created and corrected for all reported periods from the start of your MTD tax year. Incomplete records are non-compliant, even if you submit your quarterly updates on time. This means you cannot start your bookkeeping in December and backfill the year. You must record transactions as they happen, from day one.
Pro Tip: If you currently use spreadsheets or paper records, now is the time to move to cloud accounting. Bridging software exists to connect spreadsheets to HMRC, but it adds complexity. A clean migration to Xero, FreeAgent, or QuickBooks before April 2026 is far simpler than managing a bridging workaround.
4. Managing quarterly updates: deadlines and process
Quarterly updates are the defining feature of MTD ITSA, and understanding the schedule is central to any digital tax filing checklist. The standard update periods align with the tax year, and each has a fixed submission deadline.
| Quarter | Period | Submission deadline |
|---|---|---|
| Quarter 1 | 6 April to 5 July | 7 August |
| Quarter 2 | 6 July to 5 October | 7 November |
| Quarter 3 | 6 October to 5 January | 7 February |
| Quarter 4 | 6 January to 5 April | 7 May |
These standard quarterly deadlines are the default for all MTD ITSA users. You have the option to elect calendar quarters (ending 31 March, 30 June, 30 September, and 31 December) if your software supports it. Making a calendar quarter election before filing your first quarterly update helps align your bookkeeping to a more natural reporting rhythm, particularly if you already work to calendar months.
A few things to understand clearly about quarterly updates:
- They are cumulative snapshots of your income and expenses, not separate standalone reports.
- They do not trigger a tax payment. Your tax bill is still calculated at year-end.
- They are distinct from VAT quarterly returns, even if the timing looks similar.
- Quarterly updates are cumulative financial snapshots, so your bookkeeping can be incremental, but your year-end return needs complete, reconciled totals.
For 2026/27 only, HMRC has introduced a soft landing. A soft landing easement means no penalty points will be issued for late quarterly submissions in the first year. This does not apply to the year-end tax return. Miss the 31 January deadline for your final return and you will face penalties as normal.
Pro Tip: Set calendar reminders for each quarterly deadline the moment you sign up for MTD. Reconcile your transactions monthly rather than leaving three months of bank entries to sort through the week before the deadline. Thirty minutes a month beats a full weekend of bookkeeping chaos.
5. Understanding exemptions and how to apply
Not everyone must comply with MTD ITSA, and the digital tax requirements include a formal exemption process. Exemptions exist for digital exclusion and other qualifying criteria. Some are granted automatically; others require a formal application to HMRC.
The categories of exemption include:
- Age. Taxpayers who are elderly and unable to use digital tools may qualify.
- Disability. A physical or mental disability that prevents digital record-keeping is grounds for exemption.
- Remote location. If you live in an area with no reliable internet access, you can apply on this basis.
- Religious objection. Members of certain religious communities whose beliefs prevent the use of computers may be exempt.
- Temporary exemption. Available until at least April 2027 for those in transitional circumstances.
Exemption is a formal status requiring either automatic qualification or a submitted application. Being uncomfortable with technology or preferring paper does not qualify. You must meet one of the defined criteria and, where required, submit your application to HMRC before your mandation date.
If your exemption is granted, you continue to file your tax return through Self Assessment as normal. Your obligations do not disappear. They simply remain in the existing format rather than shifting to the MTD ITSA system. Apply early. HMRC processing times mean a late application could leave you technically non-compliant while waiting for a decision.
6. Preparing for the year-end submission
Quarterly updates are the ongoing rhythm of MTD ITSA, but the year-end submission is where your tax liability is formally calculated and confirmed. This step is not optional and carries no soft landing protection.
- Finalise your records before 5 April. All income and expenses for the tax year must be recorded and reconciled in your software before you can complete the year-end submission.
- Reconcile your bank accounts. Every transaction in your software should match your bank statements. Unexplained differences will create errors in your final return.
- Review your quarterly figures. Because quarterly updates are cumulative, any corrections made in later quarters should already be reflected. Do a final check to confirm.
- Submit your final return by 31 January. The year-end tax return deadline remains 31 January following the end of the tax year. For the 2026/27 tax year, this means 31 January 2028.
- Pay any tax owed on time. The payment deadline also remains 31 January. Late payment attracts interest and surcharges regardless of whether your return was submitted on time.
Even under the soft landing, disciplined compliance scheduling and year-end reconciliation are essential to avoid penalties. The soft landing only covers quarterly update lateness in 2026/27. It offers no protection for a late year-end return. Treat 31 January as an absolute deadline, not a target.
Keeping disciplined records throughout the year makes this final step straightforward. If you have reconciled your accounts monthly and submitted each quarterly update on time, your year-end submission becomes a confirmation rather than a scramble. The sole trader bookkeeping system setup guide from Cwabc explains how to build that habit from the start.

My honest view on getting MTD right
I have worked with sole traders and landlords who have been anxious about Making Tax Digital since it was first announced. The most common mistake I see is waiting. People assume they have time, or they hope the rules will change again. Some have already been caught out by that thinking once before when earlier MTD deadlines were postponed.
The truth is that the April 2026 mandation date is firm for those earning above £50,000. And the structure of MTD ITSA, four quarterly updates plus a year-end return, is genuinely manageable if you set up your software correctly and keep your records tidy throughout the year. The problem is not the system itself. The problem is arriving at it unprepared.
What I tell every client is this: the quarterly update is not a tax payment. It is a progress report. Once you understand that, the anxiety drops considerably. You are not paying more tax more often. You are simply telling HMRC what you have earned and spent, four times a year, so the year-end calculation is already mostly done.
The one thing I would push back on is the idea that MTD is purely a burden. For clients who previously had no real bookkeeping system, the requirement to use software like Xero or FreeAgent has actually improved their financial picture. They know their numbers. They spot problems earlier. They are less likely to face a surprise tax bill in January.
If you are in scope for April 2026, the time to act is now, not in December. Get your software chosen, get your records started, and if you are unsure, get professional support early. The MTD ITSA guide for 2026 to 2028 covers the full timeline if you want to read ahead.
