Making Tax Digital Phase 2: What Every UK Small Business Needs to Know in 2026

What Is Making Tax Digital Phase 2 and Why Should You Care?

HMRC is fundamentally changing how self-employed people and landlords file their taxes. From April 2026, it's no longer optional. It's law.

Making Tax Digital Phase 2 (officially called "ITSA"—Income Tax Self Assessment) requires you to keep your business records digitally and file quarterly updates with HMRC throughout the tax year, not just once a year at the end.

The panic you're hearing from accountants, bookkeepers, and business owners? It's real. But it's manageable if you understand what's happening and start preparing now.

Here's the situation in plain English:

From April 2026 (Year 1): Self-employed people and landlords earning over £50,000 must file quarterly. No exceptions. No spreadsheet workarounds. You submit your profit figures to HMRC every three months.

From April 2027 (Year 2): The threshold drops to £30,000. Virtually all self-employed people and buy-to-let landlords have to do it.

Why HMRC is doing this: They want real-time visibility into your finances. No more guessing. No more waiting until self-assessment to find mistakes. They file updated tax figures quarterly, so they know your tax bill throughout the year.

For you, the upside is that if you get a tax bill, you see it coming in quarterly updates rather than getting a shock in January.

The downside is admin. You need to keep digital records, understand your quarterly profit, and submit to HMRC four times a year instead of once.

The good news? If you're already using proper invoicing or accounting software, MTD Phase 2 is basically already handled. If you're using a spreadsheet, it's time to move.

Who Is Actually Affected by MTD Phase 2?

Let's be clear about who has to do this:

You're Definitely Affected (from April 2026):

Self-employed sole traders earning over £50,000
Self-employed partners in a partnership (based on your share of profit)
Landlords with rental income over £50,000
Freelancers earning over £50,000 (you're self-employed)
Directors of limited companies earning over £50,000 as personal income

You're Definitely Not Affected:

Limited company directors (your company files under different rules—Company Tax Return, not ITSA)
Employees (your employer handles tax via PAYE)
Self-employed earning under £50,000 (for now—this drops to £30,000 in April 2027)

You Might Be Affected (Check Your Numbers):

Part-time self-employed earning close to £50,000
Multiple income streams (e.g., self-employed plus rental income)—your total counts
Landlords with multiple properties where combined income is over £50,000

Action: Calculate your current or expected income. If you're over £50,000 or expect to be by April 2026, you need to act. If you're under £50,000 now but growing, start preparing anyway—the threshold drops in April 2027.

What Exactly Does MTD Phase 2 Require?

Let's break down what you actually have to do:

1. Keep Digital Records

You must keep:

Invoices (issued and received)
Receipts for every expense
Bank statements (or at least a record of every transaction)
Mileage logs (if claiming travel)
Payroll records (if you have employees)
VAT records (if VAT-registered)

All of this must be:

Kept digitally (not paper—though you can scan paper receipts)
Stored for at least 5 years
Available to produce to HMRC if asked
Linked to your business accounts

Good news: You probably already keep most of this. The key is keeping it digitally and organised.

2. Calculate Your Quarterly Profit

Every three months (quarter), you need to know:

How much money came in (turnover)
How much you spent (expenses)
Your profit (turnover minus expenses)

This isn't your bank balance. It's your profit calculated under tax rules.

Example: You're a plumber.

April–June: £22,000 in invoices issued, £4,000 in expenses paid. Profit = £18,000.
July–September: £20,000 invoices, £3,500 expenses. Profit = £16,500.
October–December: £19,000 invoices, £4,200 expenses. Profit = £14,800.
January–March: £21,000 invoices, £5,000 expenses. Profit = £16,000.

Total for year: £65,300 profit (used for tax calculation).

You report each quarter's profit to HMRC, not the total at the end.

3. File Quarterly Returns with HMRC

You must file:

Quarterly return (profit figure for that quarter) to HMRC within 5 months of the quarter end
Final declaration (your full-year position) by 31 January after the tax year ends

Your filing deadline is 5 months after the quarter ends:

Q1 (Apr–Jun): File by 30 November
Q2 (Jul–Sep): File by 28 February
Q3 (Oct–Dec): File by 31 May
Q4 (Jan–Mar): File by 31 January (next year)

Critical: Missing a filing deadline means penalties. HMRC is strict on this.

4. Use MTD-Compatible Software

You must use software that:

Is on HMRC's list of MTD-compatible products
Can file directly with HMRC (or can export data you can file manually)
Keeps records in the right format
Handles quarterly calculations

You can't file manually. You can't use a spreadsheet that doesn't integrate with HMRC. You need software.

What "MTD-Compatible Software" Actually Means

Here's where the confusion starts. HMRC says you need "MTD-compatible software," but what does that mean?

MTD-Compatible = Software on HMRC's List

HMRC maintains a list of products that are MTD ITSA-compatible. These products can:

Connect to HMRC's system via an API (Application Programming Interface)
File quarterly returns automatically (you don't manually type them into HMRC's website)
Keep records in a format HMRC accepts (digital, timestamped, linkable)

Most UK invoicing and accounting software is on this list:

Xero ✓ (files automatically)
FreshBooks ✓ (files automatically)
QuickBooks Online ✓ (files automatically)
Coconut ✓ (files automatically)
Tide ✓ (files automatically)
Wave ✓ (with some caveats)
Sage 50 ✓ (older software but MTD-ready)

See the full list on gov.uk: Software for MTD.

What MTD-Compatible Means in Practice

Let's use Xero as an example:

You create an invoice in Xero (e.g., invoice for £2,000)
Xero records it as income earned
You record an expense in Xero (e.g., £300 for supplies)
Xero calculates your profit for that month
At the end of the quarter, Xero shows you: Profit = £X,XXX
You click "File Quarterly Return" in Xero
Xero connects to HMRC and submits your figures automatically
HMRC receives it and sends you a confirmation

With Wave or Coconut, the process is similar, but you might get a notification to "file your return" which you then submit.

With a spreadsheet? You can't do any of this. HMRC won't accept a spreadsheet upload.

How to Prepare for MTD Phase 2 (Step by Step)

If you're currently using spreadsheets or paper records, here's how to switch without chaos:

Step 1: Audit Your Current System (1 Week)

Make a list of:

What records you currently keep: Invoices in email? Receipts in a folder? Bank statements?
What records you're missing: Do you have mileage logs? Salary records if you have staff?
What software you're using (if any): Spreadsheet? Sage? Old accounting software?

This isn't about being perfect. You're just understanding where you are.

Step 2: Choose Software (1 Week)

Look at our guide Best Invoicing Software UK 2026 for detailed options, but in brief:

Tight budget: Wave (free) or Coconut (free/£10.80)
Growing business: Xero (£10–£50/month) or FreshBooks (£9.95–£24.95/month)
Accountant-friendly: QuickBooks Online (£5–£30/month)
Sole trader with bank account: Tide (free/£20)

All of these are MTD-ready. Choose based on what feels easiest to use during the free trial.

Step 3: Set Up Your Software (1–2 Weeks)

Go through the setup:

Enter your business details (name, address, VAT number if registered)
Add your clients (copy from your current system)
Upload your logo and set your invoice template
Connect your bank account (Open Banking)
Enter any outstanding invoices (unpaid work from previous months)

Most software has a guided onboarding. Don't skip it.

Step 4: Migrate Your Current Records (2–4 Weeks, Ongoing)

This is the tedious bit.

For invoices: If you have invoices from the last 6 months that are unpaid, enter them into your software so you can track them properly.

For receipts: Don't try to enter every receipt from the past 5 years. Start fresh from now. Photograph or scan your recent receipts and upload them as you go.

For bank transactions: Your software will pull the last 90 days of bank transactions automatically via Open Banking. For older transactions, you can manually categorise them over time.

Pro tip: Don't try to be perfect. Your software doesn't need to have every receipt from 2021 entered by day one. You just need to start the system and build from here. HMRC cares about forward records, not retroactive perfection.

Step 5: Set Up Quarterly Reminders (1 Day)

Most software will remind you, but set calendar reminders for your filing deadlines:

30 November (Q1: April–June)
28 February (Q2: July–September)
31 May (Q3: October–December)
31 January next year (Final declaration)

Missing a deadline costs you penalties. Don't rely on remembering.

Step 6: Test a Quarterly Filing (1 Hour)

When your first quarter is approaching (by mid-November), test the filing process:

Open your software
Look at your Q1 figures (profit)
Click "File quarterly return" (or whatever your software calls it)
Follow the prompts to submit to HMRC

This is a dry run. You want to know how it works before you actually submit. If you get stuck, contact support before the deadline.

Step 7: File Your First Quarter (30 Minutes)

Once you've done the test, filing takes 30 minutes. You're literally just confirming the figures and submitting.

How to Calculate Your Quarterly Profit (The Bit HMRC Cares About)

Your quarterly profit isn't your bank balance. It's your income minus expenses under tax rules.

Income

Count:

Invoices issued (not cash received—invoices issued during the quarter)
Cash payments for work done (if you're paid cash)
Other income (interest, equipment sold, etc.)

Don't count:

VAT (if VAT-registered, VAT is separate)
Loans or borrowings (not income)

Expenses

Count:

Supplies and materials (equipment, parts, stock)
Vehicle costs (fuel, maintenance, insurance, MOT—or mileage allowance)
Office costs (rent, rates, utilities, internet)
Professional fees (accountant, insurance, memberships)
Staff costs (wages, employers' NI, pension contributions)
Depreciation (equipment wearing out—you claim a percentage)
Travel and subsistence (hotels, meals while working away)

Don't count:

Capital purchases (buying equipment—you claim depreciation instead)
Loan repayments (only the interest counts)
VAT you paid (if VAT-registered, HMRC refunds this separately)
Personal expenses (your own meals, clothes, household bills)
Tax payments (income tax, NI, VAT paid—these aren't expenses)

Example: Plumber, Q1 (April–June 2026)

Income:

Invoices issued: £22,000
Total income: £22,000

Expenses:

Van fuel: £800
Parts and materials: £3,200
Tool maintenance: £200
Insurance (van + public liability): £400
Phone and internet: £150
Website hosting: £50
Accountant fees (quarterly): £300
Training course: £100
Total expenses: £5,200

Profit: £22,000 − £5,200 = £16,800

This is the figure you report to HMRC for Q1.

Note: If you're VAT-registered, you also calculate VAT (usually 20% of your profit), but that's a separate submission.

Your software does this calculation automatically. You don't have to do it manually. But understanding it helps you know if the software is showing the right number.

Common Myths About MTD Phase 2 (Busted)

Myth 1: "I Can Use a Spreadsheet If I'm Careful"

Reality: No. HMRC will not accept spreadsheet uploads. You must use MTD-compatible software. The software must file directly with HMRC via an API connection. A spreadsheet doesn't connect to HMRC's system. You'll be non-compliant.

Myth 2: "I Can File Late If I Explain to HMRC"

Reality: HMRC has no tolerance for late filing. Late filing = automatic penalty, even if your figures are right. First late filing: £100 (if filed within 3 months). Keep being late and penalties go up to £1,000 or more. Set reminders. File on time.

Myth 3: "My Accountant Will File for Me"

Reality: Possible, but rare. Most accountants expect you to file quarterly returns (that's the whole point of MTD Phase 2—real-time reporting, not once-yearly). Your accountant might help you set up software or review your figures, but filing is your responsibility.

Myth 4: "I Don't Need to Keep Receipts Anymore"

Reality: You need to keep receipts more than ever. HMRC can ask you to produce evidence of every expense you claim. Digital records and receipts prove your expenses are real. Keep receipts for 5 years.

Myth 5: "MTD Phase 2 is Just for Big Businesses"

Reality: MTD Phase 2 applies to self-employed and landlords earning over £50,000. That includes solopreneurs, freelancers, tradespeople, and buy-to-let landlords. If you're self-employed and earning over £50,000, it applies to you. And from April 2027, it applies at £30,000.

Myth 6: "I Can Stop Filing Self-Assessment Returns"

Reality: You still file a self-assessment return at the end of the year. MTD Phase 2 is in addition to self-assessment, not instead of it. You file quarterly returns to HMRC during the year, then you file a final self-assessment return in January.

Myth 7: "If I'm Under £50,000, I Don't Need to Prepare"

Reality: If you're under £50,000 now but expecting to grow, or if the threshold dropping to £30,000 will catch you, start preparing now. You have 1 year warning before the threshold drops. Use that time.

MTD Phase 2 and Different Types of Self-Employed

How MTD Phase 2 affects you depends on what you do:

Sole Trader (Plumber, Electrician, Builder)

You file quarterly returns starting April 2026 if you earned over £50,000 last year (or expect to this year).

Your quarterly return shows: Total invoices issued minus total expenses.

Software to use: Xero, Tide, or Coconut (all designed for tradespeople and handle quarterly filing).

Time commitment: 15–30 minutes per month to log expenses, 30 minutes to file each quarter.

Freelancer (Designer, Copywriter, Virtual Assistant)

If you earned over £50,000, same rules apply.

Your quarterly return shows: Invoices issued minus expenses (including home office, software subscriptions, professional fees).

Software to use: FreshBooks or Coconut (both designed for freelancers).

Time commitment: Minimal if you use invoicing software (most of it's automatic). Filing takes 20 minutes per quarter.

Landlord (Buy-to-Let)

If your rental income (not including capital gains) is over £50,000, you file quarterly.

Your quarterly return shows: Rental income minus expenses (mortgage interest, maintenance, insurance, agent fees).

Special note: You can't deduct mortgage capital repayment, only interest. And stamp duty doesn't count as an expense.

Software to use: Xero or QuickBooks Online (both handle rental properties well).

Time commitment: 15–30 minutes per month.

Partner in a Partnership

If your share of partnership profit is over £50,000, you file quarterly for your share.

Your quarterly return shows: Your share of profit.

Software: The partnership usually uses one software (e.g., Xero), and you file your individual returns based on your share.

Time commitment: Depends on the partnership's record-keeping.

Director of a Limited Company (But Also Self-Employed)

This is a gap in MTD Phase 2. If you're a limited company director, your company files a different return (Corporation Tax, not ITSA). But if you also have self-employment income (e.g., freelance work, rental property), that income is filed under MTD.

Software: Two systems (one for your company, one for your self-employed income).

Time commitment: Higher because you're tracking two tax positions.

How to Get Your Software to File MTD Returns

Once you've set up your software and logged a quarter's worth of data, here's how to actually file:

Step 1: Check Your Quarterly Figures

Open your software and look at your dashboard. You should see something like:

Q1 Summary (April–June 2026):
- Income: £22,000
- Expenses: £5,200
- Profit: £16,800

If these numbers don't look right, check your transactions. Make sure you've logged all invoices and expenses for that quarter.

Step 2: Authorize Your Software to Connect to HMRC

Most software asks you to do this once. You'll be asked to:

Log in with your personal Government Gateway account (the account you use for Self-Assessment)
Authorise the software to file returns on your behalf
Confirm your consent

This is a one-time setup. After that, your software can file without asking again.

Step 3: File Your Quarterly Return

When your filing deadline is approaching, your software will prompt you to "File quarterly return" or similar. Click it.

You'll see your profit figure and you'll be asked to confirm:

"Is this correct?"
"Do you have any other income sources you need to add?"
"Are you happy to file this with HMRC?"

Answer yes and file.

Step 4: Get Confirmation

HMRC will send you a confirmation email saying your return has been received and processed. You'll also see it in your software. Keep this confirmation for your records.

Step 5: Pay Any Tax Owed

Depending on your circumstances, you might owe tax now or at the end of the year. Your software will tell you your estimated tax liability.

Options:

Quarterly payments: Some businesses make tax payments throughout the year
Year-end payment: Pay everything in January

HMRC will let you know if you're required to make payments.

What Happens If You Miss a Filing Deadline?

Let's be blunt: penalties are real and they hurt.

Late Filing Penalties

1–3 months late: £100 penalty (automatic, no questions asked)
3–6 months late: £100 + 5% of tax owed (if you owe tax)
6+ months late: £100 + 5% of tax owed, plus interest accruing monthly

Example: You owe £5,000 tax and you file 4 months late. Your penalty is £100 + (5% of £5,000) = £350. Plus interest.

Non-Compliance Penalties

If you don't file at all:

First offence: £100 + interest
Repeated offence: Up to £1,000 per quarter

Interest Accrues

Even if you pay the penalty, interest continues to accrue on the tax you owe until you pay. Interest is charged at Bank of England base rate + 2.5%.

At current rates, that's roughly 7–8% per year on unpaid tax.

Example: You owe £5,000 tax and file 6 months late. The penalty is £350. Interest costs you an additional £200+ for being late.

The Reputation Hit

If you're repeatedly non-compliant, HMRC flags you for compliance reviews. You might be audited more frequently or challenged on expenses you'd normally claim without question.

Best practice: Set calendar reminders and file 2 weeks early. Don't leave it to the last day.

Which Software Is Genuinely MTD-Ready for Phase 2?

Here's a quick summary of which software is confirmed MTD ITSA Phase 2-ready (as of March 2026):

| Software | MTD ITSA Ready | Auto-Files? | Cost | Best For | |----------|---|---|---|---| | Xero | ✓ Yes | Yes | £10–£50/month | All-rounder, VAT-registered | | FreshBooks | ✓ Yes | Yes | £9.95–£24.95/month | Freelancers, time tracking | | QuickBooks Online | ✓ Yes | Yes | £5–£30/month | Accountant-friendly | | Wave | ✓ Yes (limited) | Partial | Free | Tight budgets | | Coconut | ✓ Yes | Yes | Free–£10.80/month | Solo freelancers | | Tide | ✓ Yes | Yes | Free–£20/month | UK sole traders, bank account | | Zoho Invoice | ✓ Yes | Limited | Free–£55/month | Multi-user teams | | Sage 50 | ✓ Yes | Limited | £150–£500 one-time + subscription | Older but functional |

Most important: Check the current list on gov.uk: MTD software before committing. HMRC updates the list regularly.

Preparing Your Records: What HMRC Wants

HMRC doesn't just want your quarterly profit figure. They want to see that your records actually support it. If you're audited, you need to produce:

Invoices

Every invoice you issued (showing customer, date, amount, description of work)
Organised by date
Including voided invoices (mark them as cancelled)

Receipts

Every receipt for claimed expenses (showing supplier, date, amount, what was bought)
Organised by category (supplies, fuel, etc.)
Photographs or scans are fine

Bank Statements

Bank statements covering the periods you claim income and expenses
Showing every transaction linked to your business

Mileage Records

If you claim vehicle mileage, records showing:
- Date of journey
- Distance travelled
- Purpose (business vs. personal)
A simple logbook is fine (paper or digital)

Payroll Records (if you have employees)

Payroll records showing wages paid
PAYE tax paid to HMRC
Pension contributions

VAT Records (if VAT-registered)

Invoices issued (showing VAT)
Invoices received from suppliers (showing VAT)
Proof of VAT payments to HMRC

You don't need to submit all of this with your quarterly returns. But if HMRC asks, you need to have it.

Storage: Keep everything for at least 5 years. Digital is fine. Cloud storage is fine (and recommended). Paper is fine but risky.

FAQs: MTD Phase 2 Questions Answered

Q: What If I'm on the Borderline of the £50,000 Threshold?

A: If you earned over £50,000 last year, you're in. If you're expecting to this year, plan as if you are.

If you're borderline (e.g., £48,000 last year), start preparing now. By April 2026, the rules might be clarified further. But expect to be caught.

Q: Do I Need to File if I Earned Less Than £50,000?

A: You still file a self-assessment return (once yearly). But you don't file quarterly returns under MTD Phase 2 unless you're over £50,000.

However, this changes in April 2027 when the threshold drops to £30,000. If you're over £30,000 but under £50,000, prepare now.

Q: Can My Accountant File My Quarterly Returns for Me?

A: Technically yes, but it's not common. Your accountant would need authority to file on your behalf (via the Government Gateway).

Most accountants expect you to file quarterly (that's the automation this is meant to achieve) and they'll review your figures. They might help with setup and training, but filing is typically your job.

Q: Will MTD Phase 2 Increase My Tax?

A: No. Your tax is calculated on your profit, which doesn't change. MTD Phase 2 just files it more frequently.

However, real-time filing might catch income or expenses you previously forgot, which could mean you owe more or less tax than you expected. The advantage is you know sooner.

Q: What If I Have Accountancy Software But It's Old?

A: Check if it's on HMRC's list of MTD ITSA-compatible products. If it's 5+ years old, it probably isn't.

You might need to upgrade or switch to newer software. There's no getting around this—HMRC won't accept non-MTD-compliant software.

Q: Do I Need a New Government Gateway Account for MTD Phase 2?

A: No. You use the same Government Gateway account you already have for Self-Assessment. If you don't have one, you'll need to set it up (it takes 10 minutes at account.tax.service.gov.uk).

Q: What If I'm Moving Abroad or Retiring in 2026?

A: You still need to file if you have UK self-employed or landlord income, even if you live abroad.

If you're genuinely stopping self-employment before April 2026, inform HMRC and you might be exempt. But get advice first.

Q: Will MTD Phase 2 Affect My VAT Filing?

A: Yes. If you're VAT-registered, your VAT return is also filed separately, typically quarterly or monthly depending on your registration.

MTD Phase 2 is separate from VAT, but many software solutions handle both. The deadlines are different, so don't confuse them.

Q: What If I Use Multiple Bank Accounts?

A: Your software needs to connect to all of them for accurate record-keeping. Most software handles multiple bank accounts. Just connect each one during setup.

Q: Can I Change Software After I've Started Filing?

A: Yes, but it's messy. Your new software needs to import your old records, and the transition needs to be done carefully so HMRC doesn't see a gap.

Better to get the right software now and stick with it.

Q: What About Expenses I Claimed Last Year But Might Get Queried On?

A: MTD Phase 2 doesn't change what you can claim. You can claim the same expenses you always could.

But HMRC will have visibility into your income and expenses quarterly (not once yearly), so if something looks odd, they might ask sooner.

Keep good records and claim only legitimate business expenses. This hasn't changed.

Q: If I Miss the April 2026 Deadline, Can I Catch Up Later?

A: Technically yes, but penalties apply immediately. The first late filing (by November 2026) costs you £100. Filing 6 months late costs you £100 + interest + penalties on tax owed.

Don't rely on "catching up later." File on time.

The Real-World Impact: What This Means for Your Business

Let's zoom out. What does MTD Phase 2 actually mean for you day-to-day?

More Admin Upfront, Less Stress Later

You'll spend an extra 30–60 minutes per month setting up your software and logging expenses. But you'll spend less time at tax time because everything is already done.

Trade-off? Net positive. You save time overall.

Real-Time Tax Clarity

Every quarter, you'll know exactly what tax you owe. No shocks in January. You can budget for it, set money aside, or adjust your income if you're falling short.

That's worth something.

Better Business Insights

Your quarterly reports show you:

What income you actually earned (not bank balance, real profit)
Where you're spending money
Which clients are most profitable
Whether you're on track for your annual targets

Many businesses make better decisions with this visibility.

Compliance Peace of Mind

You're filing real-time with HMRC. You're not scrambling to recreate records at tax time. If an audit happens, your records are already perfect.

That's peace of mind that spreadsheets don't give you.

Early Preparation Required

Between now and April 1st, 2026 (5–6 weeks away), you need to:

Choose and set up software
Migrate your current records
Test your first quarter filing
Understand your quarterly profit

It's doable if you start now. It's stressful if you leave it until April.

Action Plan: What to Do This Week

By end of this week, you should have:

Confirmed you're affected. Calculate if you earned or will earn over £50,000. If yes, you're in.
Chosen software. Read Best Invoicing Software UK 2026 and pick one. Start a free trial.
Set up your software. Enter your business details, connect your bank, add a few clients.
Taken a screenshot of your government gateway account. You'll need login details to authorise filing.
Bookmarked your filing deadline. 30 November 2026 for Q1. Add it to your calendar now.

Over the next 3–4 weeks:

Migrate old invoices and receipts into your software.
Set up recurring reminders for expense logging (weekly) and filing (quarterly).
Test your first quarter filing (dry run) by mid-November.

That's it. You're MTD Phase 2 ready.

Final Word: You've Got Time, But Not Much

MTD Phase 2 isn't optional. It isn't going away. But it's also not as scary as the headlines make it sound.

The businesses that are panicking are the ones using spreadsheets or not paying attention. If you use proper invoicing software (which you should be using anyway), MTD Phase 2 is basically automatic.

The businesses that are fine are the ones getting organised now.

You're reading this in March 2026. You have a month to prepare before the rules change. Use it.

Pick software this week. Set it up. Test it. File your first quarter in November. Move on with your life.

HMRC is trying to streamline tax reporting, not destroy small businesses. Modern software makes it genuinely easy.

You've got this.
