Your MTD Roadmap: A Clear, Step-by-Step Guide to Making Tax Digital for Self-Employed People

There’s a reason that ‘where do I even start with MTD?’ is one of the most common questions we hear. Making Tax Digital introduces a set of requirements that feel unfamiliar — digital records, quarterly submissions, HMRC-recognised software, digital links — and when you look at them all at once, the whole thing can feel bigger than it actually is.

The answer to ‘where do I start?’ is almost always the same: start with what you know, and work forward from there in a clear sequence. MTD is not one big leap — it’s a series of manageable steps that, taken in the right order, build into a system that most self-employed people find considerably less daunting in practice than in prospect.

This guide gives you that sequence. Not a theoretical overview, but a practical, step-by-step roadmap covering everything from confirming your start date through to submitting your first quarterly update with confidence. Follow the steps in order and you’ll have a working MTD setup before your deadline arrives.

Before You Start: Know Your Deadline

The starting point for any MTD preparation is knowing when it applies to you — because that determines how urgently each step needs to happen.

Your MTD start date is determined by your total gross income from self-employment and property rental combined, in the previous tax year:

• Over £50,000: April 2026 — already mandated. If this applies to you and you’re not yet set up, your priority is immediate action.
• Over £30,000: April 2027 — you have time, but preparation should begin now
• Over £20,000: April 2028 — early preparation is still valuable
• Below £20,000: not currently required, though this may change

 

Note that rental income counts towards your total. If you earn from both self-employment and property, add both figures together before checking your threshold.

💡 Crew Insight A surprising number of self-employed people discover, when they sit down and calculate properly, that they’re in an earlier MTD cohort than they assumed. The most common reason is forgetting to include rental income, or underestimating their gross (pre-expenses) income. Getting this right at the outset shapes everything that follows.

 

Step 1: Take Stock of Your Current Record-Keeping

Before choosing software or making any changes, spend time understanding your current system. This step isn’t about judging what you have — it’s about knowing what you’re working with so the transition is realistic.

Ask yourself:

• How do I currently record income and expenses? (Paper, spreadsheet, software, a mix?)
• How current are my records at any given point in the year?
• Do I have a clear, consistent set of income and expense categories?
• Are all my business transactions going through a dedicated business bank account?

 

The answers to these questions tell you how much work lies between your current position and a working MTD setup. Someone with current digital records and a separate business account is much closer than someone working from a mixture of paper receipts and occasional memory.

💡 Crew Insight If you do not yet have a separate business bank account, setting one up before your MTD transition is strongly worth doing. A dedicated account makes bank feed connections clean and unambiguous, and eliminates the need to sift through personal transactions for business ones. It’s a small step with a disproportionately large impact on how easy your record-keeping becomes.

 

Step 2: Choose Your MTD Software

This is one of the most consequential decisions in your MTD setup — not because it’s irreversible, but because starting with the right platform is simpler than switching later. The core requirement is HMRC recognition for MTD submissions. Beyond that, the choice should reflect your working style and the complexity of your finances.

The two platforms we recommend to self-employed clients are:

FreeAgent

Our most common recommendation for sole traders. FreeAgent is designed specifically for freelancers, contractors, and self-employed people. It has a clean, intuitive interface, excellent bank feed integration, automated categorisation, and a quarterly submission process that — once you’re set up — takes minutes. It handles MTD’s digital link requirement automatically.

Xero

The better choice for self-employed people with more complex needs: VAT registration, multiple income streams, employing staff, or wanting more sophisticated financial reporting. Xero is fully MTD-compatible and highly capable, but comes with a slightly steeper learning curve.

As an Accounting Crew client, you access 50% off FreeAgent and 20% off Xero — making either platform very cost-effective.

💡 Crew Insight The temptation to over-engineer the software choice is real. We’ve seen self-employed people spend weeks comparing every platform on the market before concluding that FreeAgent or Xero is the right answer — which is almost always the case for typical self-employment. If you’re unsure, tell us a bit about your situation and we’ll give you a straightforward recommendation.

 

Step 3: Set Up Your Software Account

Once you’ve chosen your platform, setting up your account involves a few core tasks:

• Enter your personal and business details
• Set up your income and expense categories — match these to how your business actually operates
• Import any existing records if you’re mid-year (your accountant can help with this)
• Review and adjust the default settings so the platform reflects your specific business

 

This setup phase is also the right time to make sure your business bank account is ready for the next step.

Step 4: Connect Your Bank Account

One of the most powerful features of modern MTD software is the bank feed — an automated connection between your software and your bank account that imports transactions in real time, without any manual data entry.

Once connected, transactions appear in your software automatically. You review and categorise them — something that takes a few minutes per week rather than a concentrated catch-up session at quarter end. This single feature does more than anything else to make MTD record-keeping sustainable alongside a busy working life.

Most major UK banks are supported by both Xero and FreeAgent. The connection process typically involves logging into your online banking within the software and authorising the feed — a one-time task.

💡 Crew Insight Clients who resist the bank feed — often because it feels like giving up control — almost universally change their view once they’ve used it for a quarter. The alternative is manually entering or importing transactions, which is more time-consuming and more prone to error. The bank feed is not a loss of control; it’s an automation of a task that doesn’t benefit from being manual.

 

Step 5: Authorise Your Software to Connect to HMRC

For your software to submit MTD updates directly to HMRC, you need to grant it authorisation. This is done through your HMRC online account — you log in, navigate to your MTD settings, and authorise your chosen software. The process typically takes less than ten minutes and is a one-time setup.

Once authorised, your software can submit quarterly updates directly to HMRC on your behalf. You review and approve each submission before it’s sent — so you retain full control over what’s submitted and when.

Step 6: Build Your Quarterly Routine

With software set up, bank connected, and HMRC authorised, you have a working MTD system. The final step is establishing the quarterly routine that makes it sustainable.

The routine we recommend for most self-employed people looks like this:

• Weekly or fortnightly: review and categorise new bank transactions in your software. With a bank feed, this typically takes 10–15 minutes.
• Monthly: a brief review of your income and expense summary to check for anything unusual or missing.
• End of quarter (April, July, October, January): review your quarterly figures, make any corrections, and submit your quarterly update to HMRC. With current records, this typically takes under an hour.
• End of tax year: your accountant reviews the year’s figures, applies allowances and adjustments, and submits the final declaration.

 

The quarterly submission itself is genuinely quick when records are current. The discipline is in the regular maintenance — not in any single submission event.

Common Roadmap Errors

Error: Skipping the bank feed

Choosing to enter transactions manually or import them via spreadsheet creates unnecessary work and breaks the digital link requirement. The bank feed is not optional for a well-functioning MTD setup.

Error: Treating quarterly submissions as year-end events

Leaving record-keeping until the end of each quarter — rather than maintaining it weekly — makes each quarterly submission significantly more work and more stressful. The quarterly rhythm should distribute work across the period, not concentrate it at the deadline.

Error: Not reviewing submissions before sending

Both Xero and FreeAgent show you a summary of your quarterly figures before submission. Taking five minutes to review this summary — checking that income looks right and no unusual categories have appeared — is a worthwhile habit that catches errors before they go to HMRC.

💡 Crew Insight The most important mindset shift for MTD is from ‘annual admin task’ to ‘ongoing financial management’. The self-employed people who find MTD easiest are those who think of their accounts as a living record of their business rather than a document produced once a year for HMRC. MTD enforces that shift — and most people, once they’ve made it, find it genuinely preferable.

 

The Accounting Crew’s Perspective

The roadmap above reflects exactly how we guide clients through MTD transitions. The sequence matters: confirm your threshold, understand your starting point, choose the right software, connect your bank, authorise HMRC, establish your routine. Done in order, with enough lead time, the whole process is manageable for any self-employed person regardless of their starting familiarity with digital tools.

Where we add value is in handling the technical elements — setup, configuration, HMRC connection, quarterly submission support — so that the only thing you need to focus on is keeping your records current during the quarter. That’s a reasonable ask, and with bank feeds doing most of the heavy lifting, it’s a manageable one.

Conclusion

MTD doesn’t need to be complicated or stressful. It needs a clear sequence, the right tools, and enough lead time to get comfortable before your mandatory start date arrives. The steps in this guide give you that sequence — and each one builds on the last to produce a working MTD setup that runs quietly and efficiently alongside your business.

Whether you’re starting from paper records or already partway through a digital transition, the path is clear. The best time to begin is now — not when the deadline is imminent.

Frequently Asked Questions

How long does it take to get fully set up for MTD?

For most self-employed people, the technical setup takes a few hours spread over one or two sessions. Getting fully comfortable with the quarterly routine typically takes two or three quarters of practice. Starting six months before your mandatory date gives you comfortable runway for both.

What are the quarterly submission deadlines under MTD?

Quarterly update deadlines are currently set at one month after the end of each quarter. For a standard April-to-March tax year: 5 August, 5 November, 5 February, and 5 May. Your software will track and remind you of these dates.

Can I use MTD software on my phone?

Yes — both Xero and FreeAgent have mobile apps that allow you to categorise transactions, capture receipts, and review your financial position on the go. Many self-employed people find the mobile app more convenient for day-to-day record-keeping.

What if I make an error in a quarterly update?

Errors in quarterly updates can be corrected in subsequent quarters or in the final end-of-year declaration. Quarterly updates are not final — they’re working summaries. The year-end declaration is where your position is formally confirmed and adjusted.

Do I still need a Self Assessment after MTD?

For income covered by MTD (self-employment and property), the annual Self Assessment return is replaced by the quarterly updates and end-of-year declaration. If you have other income sources not covered by MTD — such as employment income, dividends, or capital gains — you may still need to file a Self Assessment for those elements.
