Best MTD-Compatible Software for UK Businesses (2026 Guide): What to Use for MTD for Income Tax

Making Tax Digital (MTD) for Income Tax Self Assessment (often shortened to MTD for Income Tax or MTD ITSA) is the biggest change to how sole traders and landlords keep records and report income to HMRC in a generation. If you’re in scope from April 2026, choosing the right MTD-compatible software is one of the most practical decisions you’ll make this year.

This guide is written for Self-Employed and Landlords. We’ll cover what “MTD-compatible” really means, which tools are worth considering in 2026, and how to choose software that fits your day-to-day life (not just HMRC’s rules). We’ll also set out the rollout timetable, because the date you need to comply depends on your income.

MTD for Income Tax (ITSA) rollout: the key dates (2026–2028)

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

If you’re close to a threshold, it’s sensible to prepare early. Even if you’re not mandated until 2027 or 2028, getting your records tidy now can save a lot of stress later.

What counts as “MTD-compatible software” (and what doesn’t)

For MTD for Income Tax, HMRC expects you to:

• Keep digital records of your business and/or property income and expenses.
• Send quarterly updates to HMRC using MTD-compatible software.
• Complete an end-of-year process (often described as EOPS and a Final Declaration) through software.

In plain English: you’ll need a tool that can store your records digitally and submit the required updates to HMRC. “MTD-compatible” usually means one of the following:

• Full accounting software (you keep your books inside the software and it submits to HMRC).
• Bridging software (you keep your records in a spreadsheet, then the bridging tool submits to HMRC).

What good MTD software should do for you (not just for HMRC)

When clients ask us what to choose, we steer the decision towards everyday usability. The best software is the one you’ll actually keep up to date. For most self-employed people and landlords, the essentials are:

Best MTD-compatible software in 2026: our practical roundup

Below is a practical overview of commonly used MTD-compatible tools for UK sole traders and landlords. The “best” choice depends on how you work, whether you like spreadsheets, and how confident you feel with bookkeeping.

1) Xero

Best for: People who want a solid all-round system with bank feeds, invoicing, and strong reporting.

• Strengths: Bank reconciliation is straightforward; good app ecosystem; works well if you have an accountant helping you.
• Watch-outs: Can feel like “more than you need” if you have a very simple business; costs can rise as you add features or apps.
• Good fit if: You want to run your bookkeeping properly throughout the year and get cleaner numbers for quarterly updates.

2) QuickBooks Online

Best for: Self-employed people who want strong bank feed automation and a familiar “money in/money out” feel.

• Strengths: Good automation rules; helpful mobile features; solid day-to-day bookkeeping tools.
• Watch-outs: Like all software, it still needs regular review—automation can mis-categorise if you let it run unattended.
• Good fit if: Most of your transactions come through the bank and you want to keep on top of things weekly.

3) FreeAgent

Best for: Straightforward businesses who want an easy-to-follow system and clear tax-style summaries.

• Strengths: Often feels approachable for non-accountants; useful overviews; can work very well for simple setups.
• Watch-outs: Reporting and flexibility can feel limited for more complex scenarios; check it meets your exact needs for property and/or multiple income streams.
• Good fit if: You want clarity and simplicity more than deep custom reporting.

4) Sage (cloud options)

Best for: Those who prefer a more traditional bookkeeping approach and want a well-established UK brand.

• Strengths: Familiar to many bookkeepers; good core bookkeeping features; established support channels.
• Watch-outs: Interface and workflows may suit some people better than others—worth trialling before committing.
• Good fit if: You’re comfortable with bookkeeping basics and want a conventional structure.

5) Spreadsheets + bridging software

Best for: People who are disciplined with spreadsheets and have a simple, consistent transaction pattern.

• Strengths: You keep your familiar spreadsheet; often lower cost; can be perfectly workable if the spreadsheet is well designed.
• Watch-outs: You must get the structure right, keep records up to date, and maintain digital links. Spreadsheets can become messy quickly if you have lots of transactions or mixed income.
• Good fit if: You have a clean system already and you’re confident you can keep it consistent each quarter.

How to choose the right tool: a calm checklist

Here’s a practical way to narrow down your choice without getting lost in features you’ll never use.

Step 1: Be honest about your record-keeping style

• If you like spreadsheets and keep them updated monthly, consider spreadsheets + bridging.
• If you avoid bookkeeping until January, choose software with bank feeds and a simple mobile app.
• If you want visibility over profit and cashflow, pick a full bookkeeping package rather than bridging.

Step 2: List your income streams (it matters for setup)

MTD for Income Tax can apply to:

• Sole trade income (your self-employed business)
• UK property income (rental income)
• Sometimes both at the same time

If you have both self-employment and property, you’ll want software that can handle separate categories cleanly, so your quarterly updates don’t become confusing.

Step 3: Think about your “messy” areas

Most MTD problems come from a few predictable areas. When trialling software, check how it handles:

• Personal and business spending mixed together (common with sole traders)
• Cash and card transactions
• Motor costs (especially if you claim mileage)
• Use of home or simplified expenses
• Repairs vs improvements for landlords (this needs care)

Step 4: Decide how much support you need

Some people want to do everything themselves. Others want to do the day-to-day and have an accountant check things before submissions. A good question to ask is:

• Will you want your accountant to log in and help fix issues?
• Do you want software support (chat/phone) you can rely on?
• Do you need a bookkeeper to help keep things tidy monthly?

Quarterly updates under MTD ITSA: what software actually helps you submit

Quarterly updates are one of the biggest mindset shifts. They’re not the same as your final tax return, but they do need to be submitted on time and based on your digital records.

In practice, good MTD software should help you:

• See each quarter’s income and expenses clearly
• Spot missing information (uncategorised transactions, missing receipts, duplicates)
• Submit the update to HMRC directly from the software (or via bridging)
• Keep an audit trail of what was submitted and when

Year-end finalisation: you still need to get it right

MTD doesn’t remove the need for year-end work. You’ll still need to make sure the year is correct and complete. Depending on your circumstances, year-end tasks may include:

• Claiming capital allowances where appropriate
• Adjusting for private use (for example, phone or motor costs)
• Reviewing repairs vs improvements (especially for landlords)
• Ensuring income is complete and correctly dated
• Submitting the final declarations through the MTD process

This is exactly where many people still value an accountant: not because you can’t use software, but because the tax rules still need careful handling.

Budgeting for software: what it really costs

It’s sensible to budget for two things:

1. The software subscription (monthly or annual)
2. Your time (or a bookkeeper’s time) to keep records up to date

If you’re currently spending a weekend every January sorting receipts, MTD pushes that work into smaller, regular chunks across the year. The upside is less panic and cleaner numbers. The downside is you must build the habit.

Common mistakes when choosing MTD software (and how to avoid them)

A simple decision guide (choose your route)

What to do next (a sensible 30-day plan)

If you’re mandated from April 2026, aim to be up and running well before the first quarterly deadline. Here’s a calm plan that works for most people:

1. Week 1: Choose your route (full software or spreadsheet + bridging) and start a free trial.
2. Week 2: Set up categories, connect bank feeds (if using them), and agree how you’ll handle mixed transactions.
3. Week 3: Enter the last 4–8 weeks of transactions and test your routine (phone app, receipts, mileage if relevant).
4. Week 4: Produce a simple quarterly-style report and check it makes sense. Fix anything unclear now, not at submission time.

Frequently asked questions

Do I have to pay tax quarterly under MTD for Income Tax?

MTD for Income Tax introduces quarterly updates, which are reports of income and expenses. It does not automatically mean you’ll pay tax four times a year. Payment rules are separate, although HMRC has discussed changes over time. For now, focus on getting the reporting right and budgeting sensibly for your eventual tax bill.

Can I submit nil quarterly updates and do everything at year end?

In general, quarterly updates are meant to reflect your records for that period. Submitting nil updates when you have income and expenses is likely to create problems and could increase HMRC attention. It’s far better to keep your records up to date and submit properly each quarter.

If everything is digital under MTD, do I still need an accountant?

Software helps you store records and submit updates, but it doesn’t replace tax knowledge or judgement. Many people still use an accountant for year-end adjustments, checking claims, and making sure the final declaration is correct. If you’re confident and your affairs are simple, you may do more yourself—but you remain responsible for accuracy and deadlines either way.

I’m below the threshold now. Should I still change software?

If you’re likely to cross a threshold in the next couple of years, switching early can make the transition smoother. Even if you never cross, good digital records usually make Self Assessment easier and reduce last-minute stress.
