Making Tax Digital for Income Tax: Everything You Need to Know Before 6 April 2026


If you’re self-employed or earn rental income above £50,000, your tax compliance changes fundamentally from 6 April 2026. Making Tax Digital for Income Tax (MTD) replaces the annual self-assessment return with digital recordkeeping and quarterly submissions. This isn’t a minor administrative tweak. It’s a complete shift in how you manage tax throughout the year.

The annual scramble to gather receipts each January ends. Instead, you’ll maintain ongoing digital records and send HMRC four quarterly updates plus a final declaration. This creates a continuous compliance rhythm rather than a once-a-year rush. For some, this brings welcome structure. For others, it means adjusting long-established habits and investing in new software.

Understanding the requirements now gives you months to prepare properly. Rushing into MTD in March 2026 creates unnecessary stress and increases the risk of errors. This guide explains who’s affected, when deadlines fall, what software you need, and how to transition smoothly.

Who Making Tax Digital Affects from April 2026

MTD applies based on your combined qualifying income from self-employment and property. Qualifying income means gross receipts before you deduct any expenses. If you’re both self-employed and a landlord, HMRC adds the two income streams together.

The threshold for April 2026 is £50,000. HMRC determines this from your 2024/25 tax return, which is due by 31 January 2026. If your combined gross income from trading and property exceeds £50,000 on that return, you must use MTD from 6 April 2026.

This creates a tight timeline. Your 2024/25 return determines compliance just two months before MTD obligations begin. There’s no automatic registration. You must sign up for MTD yourself, choose software, and establish digital recordkeeping systems before your first quarterly deadline on 7 August 2026.

The threshold lowers over time. From April 2027, anyone with qualifying income over £30,000 must comply. From April 2028, the threshold drops to £20,000. This phased rollout eventually brings most self-employed individuals and landlords into the MTD system.

If your income fluctuates near the threshold, monitor it carefully. One strong year that exceeds £50,000 mandates you into MTD. Even if your income drops subsequently, you generally remain in MTD unless it falls below £20,000 for multiple years.

For new businesses starting during a tax year, HMRC adjusts your income to a full year equivalent. If you launch in January 2025 and earn £15,000 by April 2025, that’s treated as £60,000 annualised (£15,000 over three months = £60,000 over twelve months). This brings you into scope for MTD from April 2026 despite only showing £15,000 on your 2024/25 return.

The Correct Start Date: 6 April Not 1 April

A common misconception places the MTD start date on 1 April 2026. This is incorrect. The official mandate begins 6 April 2026, aligning with the UK tax year start.

This five-day difference matters for planning. Your first quarterly period runs from 6 April 2026 to 5 July 2026, due by 7 August 2026. If you’ve been preparing based on 1 April, your timeline calculations may be wrong.

The 6 April date also means your 2025/26 tax year remains under traditional self-assessment rules. You’ll file a normal tax return for 2025/26 by 31 January 2027. MTD only applies to periods beginning on or after 6 April 2026, so your first MTD year is 2026/27.

This gives you the entire 2025/26 tax year to prepare without MTD compliance pressure. Use this time to trial software, digitise existing records, and establish new bookkeeping rhythms.

How Quarterly Submissions Work

Under MTD, you send HMRC four quarterly updates per year showing your income and expenses for each period. These aren’t tax returns. They’re summaries of transactions that happened during the quarter.

The default quarterly periods follow the tax year:

  • Quarter 1: 6 April to 5 July (due 7 August)
  • Quarter 2: 6 July to 5 October (due 7 November)
  • Quarter 3: 6 October to 5 January (due 7 February)
  • Quarter 4: 6 January to 5 April (due 7 May)

Each update is due by the 7th of the month following the quarter end. This gives you approximately one month to compile figures and submit through your software.

Alternatively, you can elect to use calendar quarters starting from 1 April, 1 July, 1 October, and 1 January. This might suit businesses with calendar month accounting periods. The submission deadlines remain the same regardless of which quarter alignment you choose.

Quarterly updates are cumulative. You report year-to-date figures, not just the current quarter’s transactions. This means your second quarterly update shows income and expenses from 6 April through 5 October, not just the July to October period. This cumulative approach simplifies corrections. If you discover an error in quarter 1, you can fix it in quarter 2’s submission.

The quarterly updates don’t calculate your tax bill. They’re data summaries only. You’re not making quarterly tax payments based on these updates. The actual tax calculation happens at year-end through the final declaration.

Each income source requires separate quarterly updates. If you’re self-employed with a trading business and also earn rental income, you submit separate updates for each. If you have two separate trades, each needs its own quarterly update. This could mean eight quarterly submissions per year for some taxpayers.

The Final Declaration Process

After the tax year ends on 5 April, you complete a final declaration. This replaces your current self-assessment tax return and is due by 31 January following the tax year end, the same deadline as now.

The final declaration pulls together your four quarterly updates and adds information those updates didn’t include. This covers other income sources like employment income, dividends, savings interest, pension income, and capital gains. It’s also where you claim tax reliefs, personal allowances, and any adjustments not made in quarterly updates.

Your MTD software should prepopulate the final declaration with data from your quarterly submissions. You then add remaining income sources and claims. Once finalised, you submit digitally through the same software you used for quarterly updates.

The final declaration calculates your actual tax liability for the year. Any tax due is payable by 31 January, exactly as under current self-assessment rules. The payment dates haven’t changed, only the way you report information throughout the year.

This two-stage process means quarterly updates provide HMRC with real-time visibility of your trading activity, whilst the final declaration handles the comprehensive tax calculation once all information is available.

Digital Recordkeeping Requirements

MTD mandates digital records of all income and expenses. This doesn’t necessarily mean complex accounting software. Spreadsheets maintained digitally qualify as digital records, provided they’re stored electronically rather than printed and filed.

The critical requirement is digital links. Once data enters your digital system, all transfers to HMRC must happen electronically. No manual copying, retyping, or cutting and pasting. Software handles the transfer automatically.

For many taxpayers, this means cloud-based accounting software that records transactions and submits updates directly to HMRC. Popular options include QuickBooks, Xero, FreeAgent, Zoho Books, and Clear Books. HMRC publishes a full list of compatible software covering different business types and complexity levels.

Some people prefer spreadsheets for recordkeeping. If you’re using Excel or Google Sheets, you’ll need bridging software that reads your spreadsheet data and transmits it to HMRC in the correct format. Several providers offer bridging tools specifically for MTD compliance.

Your digital records must capture all business transactions as they occur. This doesn’t mean daily data entry necessarily, but it does mean recording transactions regularly rather than reconstructing them from memory months later. Weekly or fortnightly recordkeeping becomes the norm rather than annual catch-up.

The records need sufficient detail to support your tax position if HMRC queries anything. Income records should show amounts, dates, and sources. Expense records need amounts, dates, suppliers, and what the expense relates to. Digital bank feeds can automate much of this, pulling transaction data directly into your software.

Choosing the Right MTD Software

HMRC doesn’t provide MTD software. You must select and pay for third-party software yourself. The choice depends on your business complexity, technical confidence, and budget.

For straightforward self-employment or single rental property situations, entry-level software works well. Options like QuickBooks Simple Start, FreeAgent, or Zoho Books provide MTD compliance without overwhelming features you won’t use. These typically cost £10-£25 per month.

More complex businesses with multiple income streams, employees, or inventory need fuller-featured software. QuickBooks Advanced, Xero, or Clear Books offer comprehensive functionality at higher price points, usually £25-£50+ monthly.

Landlords with multiple properties might prefer property-specific software. Landlord Vision, PropertyHawk, and similar platforms understand rental income nuances and can handle multiple units, tenants, and property-specific expenses whilst remaining MTD compliant.

Key features to consider include:

  • Bank feed integration (automatic transaction imports)
  • Mobile app for on-the-go recordkeeping
  • Receipt capture via photo upload
  • Multiple user access if you work with an accountant
  • Reporting capabilities beyond basic HMRC compliance
  • Integration with other tools you already use
  • Customer support quality and availability

Most software providers offer free trials. Test several options before committing. The right software should feel intuitive rather than requiring extensive training. If you’re battling the interface after a week’s trial, try a different option.

Your accountant may recommend specific software they work with regularly. Using compatible software simplifies collaboration and can reduce accountancy fees if your accountant can access your records directly rather than recreating everything annually.

Penalty System and Soft Landing Period

MTD introduces a points-based penalty system for late submissions. Missing a quarterly update deadline earns one penalty point. When you accumulate enough points (typically four for quarterly reporters), HMRC issues a £200 financial penalty.

Points expire after 12 months of compliant submissions. If you submit all four quarterly updates and your final declaration on time, any accumulated points drop off after that compliance period.

Late payment penalties remain similar to current self-assessment rules. Tax not paid by the deadline incurs interest charges and escalating penalties based on how long payment is overdue.

Critically, HMRC has confirmed a soft landing period for the first year. Taxpayers joining MTD in April 2026 will not receive penalty points for late quarterly updates during the 2026/27 tax year. This grace period recognises the transition challenges and gives everyone time to adapt to the new rhythm.

The soft landing doesn’t extend to the final declaration. Your 2026/27 final declaration, due 31 January 2028, remains subject to normal late filing penalties. Similarly, tax payment deadlines carry standard penalties even during the soft landing year.

This grace period only applies to the April 2026 cohort. Those joining MTD in April 2027 at the £30,000 threshold won’t receive the same soft landing. Getting it right from the start matters more for later waves.

Preparing Your Business for MTD

The time to prepare is now, not March 2026. Several months of preparation prevents last-minute panic and ensures smooth transition.

Step 1: Confirm Your Income Status

Review your 2024/25 income to determine whether you’ll exceed £50,000. Include all self-employment gross receipts and rental income before expenses. If you’re close to the threshold, budget conservatively. Exceeding £50,000 by even £100 brings you into MTD.

Step 2: Research and Select Software

Don’t wait until April 2026 to choose software. Start trials now whilst you have time to evaluate options properly. Most providers offer 30-day free trials. Test two or three options to find the best fit for your needs and technical comfort level.

Step 3: Digitise Existing Records

If you currently use paper records, begin digitising now. This doesn’t mean recreating historical records digitally (though that helps), but it does mean starting digital recordkeeping for new transactions immediately. The sooner you establish the habit, the smoother your MTD transition.

Step 4: Establish Regular Recordkeeping Rhythms

Quarterly submissions work best when supported by regular data entry. Set aside time weekly or fortnightly to record transactions. This prevents the quarterly deadline becoming an overwhelming data entry marathon.

Step 5: Register for MTD

HMRC won’t register you automatically. You must sign up through the Government Gateway. Registration can begin now even though MTD doesn’t start until April 2026. Early registration lets you test the system and ensure everything connects properly.

Step 6: Talk to Your Accountant

If you use an accountant, discuss MTD sooner rather than later. They may need to adjust their service offering and pricing. Some accountants will handle quarterly submissions for clients, others will expect you to manage this yourself with their support at year-end. Clarify expectations early.

Common Concerns and Misconceptions

Several myths about MTD circulate among affected taxpayers. Addressing these helps separate fact from fiction.

“MTD means quarterly tax payments.” False. You still pay tax based on your annual liability, due 31 January and potentially payments on account in July. Quarterly submissions are reporting obligations, not payment deadlines.

“I can’t use spreadsheets anymore.” Partly false. You can use spreadsheets for recordkeeping but need bridging software to transmit data to HMRC. Direct spreadsheet upload isn’t permitted. The digital link requirement means software must handle the data transfer.

“HMRC provides the software.” False. HMRC doesn’t provide MTD software. You must choose and pay for third-party software yourself. This differs from the current system where HMRC’s online self-assessment platform is free.

“My accountant will do everything.” Maybe. Some accountants offer full MTD management including quarterly submissions. Others expect clients to handle quarterly updates themselves with accountant support only at year-end. Clarify the service level before assuming full coverage.

“I can delay if my income fluctuates.” Mostly false. Once you’re mandated into MTD based on qualifying income exceeding the threshold, you remain in MTD even if income subsequently drops. Exemptions only apply if income falls below £20,000 for sustained periods, and you must actively request removal from MTD.

The Benefits MTD Brings

HMRC presents MTD as beneficial to taxpayers despite the administrative changes. Some claimed benefits genuinely help, whilst others depend on your perspective.

Real-time visibility of your tax position throughout the year is potentially valuable. Rather than waiting until January to discover your tax bill, quarterly updates combined with software tax estimates provide ongoing awareness. This can improve cash flow planning and reduce year-end surprises.

Digital recordkeeping reduces the risk of losing critical receipts. Cloud-based software accessible from anywhere means no more shoeboxes or filing cabinets. Photos of receipts upload directly to your accounting records from your phone.

Earlier error detection is another claimed benefit. Quarterly submissions let HMRC spot potential issues during the year rather than 10 months after the tax year ended. In theory, this means fewer enquiries and quicker resolution when questions arise.

For businesses wanting better financial management anyway, MTD provides impetus to establish proper systems. The compliance requirement becomes a catalyst for improved record accuracy and financial visibility beyond tax obligations.

These benefits assume you’re comfortable with technology and willing to engage with recordkeeping more regularly. If you preferred the annual self-assessment approach and managed it successfully, MTD may feel like unwanted interference rather than helpful modernisation.

Industry-Specific Considerations

MTD applies broadly but affects different industries in different ways. Trades with predominantly cash income need robust systems for recording cash transactions digitally. Many software options allow manual cash recording or till integration for retail businesses.

Professional services with irregular large invoices benefit from bank feed automation. Software pulls invoice payments automatically, requiring only categorisation rather than full data entry. This suits consultants, lawyers, architects, and similar fee-based businesses.

Seasonal businesses face timing challenges. If your income concentrates in certain months, quarterly updates may feel unbalanced. Summer quarter shows huge activity whilst winter quarters have little. The cumulative year-to-date approach helps here, showing the full picture gradually building across the year.

Businesses with international aspects need software handling foreign currency properly. If you invoice in multiple currencies or have overseas suppliers, ensure your chosen software manages forex transactions and MTD reporting correctly.

Partnerships require careful handling. Each partner potentially has their own MTD obligations based on their individual qualifying income from all sources. The partnership itself may file partnership returns separately from individual MTD submissions.

Working with Accountants Under MTD

Your accountant relationship may change under MTD. Traditional year-end tax return preparation becomes more distributed across the year if you’re managing quarterly submissions yourself.

Some accountancy firms offer quarterly MTD management as a service. They’ll handle all four updates plus the final declaration, charging monthly or per-submission fees. This appeals to business owners who’d rather delegate compliance entirely.

Other practices expect clients to manage quarterly updates, with the accountant handling year-end finalisation, tax planning, and complex adjustments. This hybrid model keeps costs manageable whilst ensuring professional oversight at critical points.

A third model sees accountants providing software training and ongoing support without direct submission management. You learn to handle MTD yourself with expert guidance available when needed.

Clarify which model your accountant uses before April 2026. Pricing structures differ significantly. Some firms include MTD in existing fees, others charge separately for quarterly work. Unexpected fee increases in April 2026 create friction better addressed now through transparent discussion.

If changing accountants, ensure the new firm has MTD experience and clear service offerings. Not all small firms are ready for MTD client management. Larger practices generally have established MTD procedures.

What Happens If You Don’t Comply

Ignoring MTD carries consequences. If you’re mandated to join MTD based on your qualifying income but fail to register and submit quarterly updates, you’re non-compliant with legal obligations.

Initial contact from HMRC usually takes the form of reminder letters about missing submissions. The soft landing period for 2026/27 means no immediate penalty points for late quarterly updates during your first MTD year. However, persistent non-compliance leads to penalties once that grace period ends.

More seriously, failing to submit a final declaration by the 31 January deadline attracts the same penalties as late self-assessment tax returns currently. Initial penalty of £100, escalating penalties if the delay continues, and daily penalties for extended lateness.

HMRC has broader powers to investigate taxpayers who don’t engage with MTD despite being required to do so. This can trigger wider compliance reviews extending beyond just the missing MTD submissions.

If MTD genuinely creates exceptional difficulty, exemptions exist. Digitally excluded individuals (those unable to use digital tools due to age, disability, remoteness, or religious belief) can apply for exemption. However, the bar for exemption is high. Being uncomfortable with technology doesn’t qualify. You must demonstrate genuine inability to engage digitally.

Looking Beyond April 2026

MTD for income tax is part of HMRC’s broader digitalisation strategy. MTD for VAT already operates for VAT-registered businesses above the threshold. MTD for corporation tax is coming for companies. The direction of travel is clear: digital, real-time, continuous tax compliance.

Understanding this broader context helps frame MTD not as an isolated change but as fundamental transformation of the tax system. Businesses and individuals who adapt successfully to MTD for income tax will find future changes less disruptive.

The technology requirements will continue evolving. Software improves, HMRC systems develop new capabilities, and integration between different platforms expands. Early adoption positions you to benefit from these developments rather than constantly playing catch-up.

Tax agents and accountants are similarly adapting. Practices investing in technology and process changes become better equipped to support clients efficiently. Those resistant to change may struggle to serve MTD clients effectively.

For business owners, MTD forces a decision about recordkeeping and compliance management. Do you want hands-on control, delegated management, or something in between? There’s no single right answer, but avoiding the decision creates problems when deadlines arrive.
