Making Tax Digital April 2026: The Complete Survival Guide

Making Tax Digital for Income Tax Self Assessment launches on 6 April 2026. After years of delays and false starts, it is actually happening this time. HMRC has been clear: there will be no further postponements.

The problem is that only around 30% of affected businesses are even aware of the change. Meanwhile, 1.1 million people missed the 31 January 2026 Self Assessment deadline, which tells you how many people already struggle with the annual return. Quarterly reporting is going to be a rude awakening for anyone who is not prepared.

This guide cuts through the noise. It covers exactly who is affected, what the deadlines are, which software qualifies, and what you actually need to do in the next seven weeks. Bookmark it and come back when you need to.

What Is Making Tax Digital for Income Tax

Making Tax Digital (MTD) is HMRC's programme to move UK tax reporting from paper and annual returns to digital, real-time record-keeping. MTD for VAT has been mandatory since April 2022. Now it is Income Tax's turn.

From 6 April 2026, if you earn above the threshold from self-employment or property, you must:

1. Keep digital records of your income and expenses using HMRC-recognised software
2. Submit quarterly updates to HMRC through that software
3. Submit an End of Period Statement (EOPS) at the end of the tax year
4. Submit a Final Declaration (which replaces the current Self Assessment return)

The quarterly updates are not full tax returns. They are summary snapshots of your income and expenses for the period. Think of them as a progress report rather than a final exam.

You still file your annual Self Assessment as normal alongside quarterly updates. The Final Declaration effectively replaces the current Self Assessment tax return, but the deadline and the overall process of calculating your tax liability at year-end remains the same. Quarterly updates feed into that year-end figure.

Who Is Affected (and Who Is Not)

The rollout is phased by income threshold:

You ARE affected if

• You are a sole trader with gross self-employment income over £50,000
• You are a landlord with gross property income over £50,000
• You have a combination of self-employment and property income totalling over £50,000
• You are a partner in a general partnership where any partner has qualifying income over £50,000

The threshold is based on gross income (turnover), not profit. A landlord collecting £55,000 in rent but spending £40,000 on mortgage interest, repairs, and management fees still has qualifying income of £55,000. They are caught.

You are NOT affected if

• Your only income is salary and dividends from a limited company (Corporation Tax has its own separate MTD timeline, still TBC)
• Your qualifying income is below £50,000 (until the threshold drops)
• You are already using MTD for VAT only and have no self-employment or property income

The common trap for company directors

Many limited company directors think MTD does not apply to them. For your company accounts, that is correct. But if you also own buy-to-let properties, do freelance work on the side, or earn partnership income, that personal income is in scope. Your limited company tax obligations remain separate.

The Full Timeline: Every Deadline You Need to Know

Here is every date that matters for the first year of MTD for Income Tax:

The grace period you should know about

HMRC has confirmed that no penalty points will be issued for late quarterly updates during the first 12 months (April 2026 to April 2027). This means if you miss the 7 August 2026 deadline, you will not receive a penalty point.

This is a soft landing, not an excuse to ignore it. HMRC will still expect you to be submitting from day one. The grace period simply means your first late submission will not trigger the penalty points system. From April 2027 onwards, the full penalty regime applies.

What a Quarterly Update Actually Looks Like

This is where most of the fear is misplaced. Quarterly updates are much lighter than people expect.

A quarterly update is a summary of:

• Total income received during the quarter (rent collected, sales invoiced, etc.)
• Total expenses incurred during the quarter, broken down by category

You are not calculating tax. You are not filing a return. You are not doing anything with capital allowances, pension relief, or tax adjustments. Those all happen at year-end in the Final Declaration.

If you are already tracking income and expenses in accounting software, a quarterly update is essentially pressing a button. The software pulls the figures from your records and submits them to HMRC via the MTD API.

For landlords, a typical Q1 update might look like:

That is it. Submit and move on.

Software: What Qualifies and What Does Not

The non-negotiable rule

You must use HMRC-recognised software. Spreadsheets alone do not qualify. A paper ledger does not qualify. Your bank statements do not qualify.

HMRC maintains an official list of MTD for Income Tax compatible software on GOV.UK, and you should check it before committing to any product.

What the software must do

At minimum, MTD-compatible software must:

• Store digital records of income and expenses
• Submit quarterly updates to HMRC via the MTD API
• Submit End of Period Statements
• Submit the Final Declaration
• Support digital record-keeping (no manual re-entry from paper)

Bridging software

If you genuinely prefer spreadsheets, bridging software can act as a middleman. You maintain your spreadsheet, the bridging tool reads it and submits to HMRC. This worked for MTD for VAT, and some providers will offer it for Income Tax. But it is a band-aid. If your spreadsheet has errors, the bridging tool will submit those errors to HMRC.

Comparing MTD-Compatible Software Options

Here is a realistic comparison of the main options for UK sole traders and landlords:

A few things to note:

• Prices change. Check current pricing before committing.
• "Confirmed" means the provider has publicly stated they will support MTD for Income Tax. Check that support is available in the tier you are paying for, not just the premium plan.
• Some software handles VAT MTD but not Income Tax MTD. They are separate HMRC APIs. Verify that your chosen software supports the specific MTD regime you need.
• If you already use software for MTD for VAT, check whether it also supports MTD for Income Tax before assuming you are covered.

How to choose

For most people, the decision comes down to:

1. Do you already use accounting software? Check if it supports MTD for ITSA. If yes, you might just need to enable a feature or upgrade your plan.
2. Is your main income from property? Look at landlord-specific tools like Hammock, or general tools with strong property support.
3. Do you have an accountant? Ask what they recommend. Many accountants have preferred software and their workflow will be smoother if you use the same platform.
4. How much are you willing to spend? Prices range from free to £20+/month. For basic quarterly reporting, you do not need the most expensive option.

Your 7-Week Preparation Checklist

With April 2026 less than two months away, here is exactly what to do and when.

Week 1-2 (Mid-February): Establish your position

• Calculate your gross self-employment and property income for 2024/25
• Determine whether you cross the £50,000 threshold
• If you are a company director, check whether you have qualifying personal income separate from your limited company
• Check whether HMRC has written to you about MTD (they have been sending letters since late 2025)

Week 3-4 (Early March): Choose and set up software

• Research MTD-compatible software options (see comparison above)
• Sign up and start entering your records
• If you have an accountant, confirm who will submit quarterly updates
• Import or manually enter opening balances for the current tax year

Week 5-6 (Mid-March): Register and test

• Sign up for MTD for Income Tax through your HMRC online account
• Link your chosen software to HMRC (each provider has its own connection process)
• Test that the connection works (some providers offer sandbox testing)
• Set up recurring calendar reminders for quarterly deadlines

Week 7 (Late March): Final checks

• Verify all income sources are captured in your software
• Verify expense categories match HMRC requirements
• Confirm your accountant (if applicable) has agent access
• Set up a system for ongoing record-keeping (receipt scanning, bank feed, etc.)

Common Mistakes to Avoid

Using gross income when you mean net (or vice versa). The threshold is based on gross income. Many people check their profit figure and think they are below the threshold when their turnover puts them above it.

Assuming your limited company software covers it. MTD for Income Tax applies to personal income. If you use Xero for your limited company and also have rental income, you may need a separate MTD setup for the property income, or you need to add it to the same Xero account with proper separation.

Waiting for HMRC to tell you. HMRC has been sending letters, but not everyone has received one. Do not wait. Check your own figures.

Trying to stay below the threshold artificially. HMRC uses the most recent available data to determine eligibility. Deliberately suppressing income to avoid MTD obligations will attract scrutiny and does not change your underlying tax liability.

Ignoring it because of the grace period. The grace period means no penalty points in year one. It does not mean you are exempt from submitting. HMRC still expects compliance from 6 April 2026.

How MTD Fits With Everything Else

MTD for VAT (already live)

If you are VAT-registered, you have been using MTD for VAT since April 2022 at the latest. MTD for Income Tax is a separate obligation on top of that. You may need your software to handle both, or you may use different tools for each.

Corporation Tax

MTD for Corporation Tax has no confirmed start date. HMRC has indicated it will happen eventually, but there is no timeline. Your limited company's corporation tax obligations are unchanged for now. Use the Corporation Tax Calculator to estimate your liability.

Self Assessment

Your annual Self Assessment does not disappear. The Final Declaration under MTD effectively replaces the Self Assessment tax return, but the deadline (31 January) and the process of calculating your total tax liability remain the same. The quarterly updates feed into that final figure. Check the Making Tax Digital deadlines page for the full schedule.

Payments on Account

Payments on Account (the July and January advance payments towards next year's tax bill) continue as normal. MTD does not change when or how much you pay — only how you report.

What Happens If You Do Not Comply

After the first-year grace period ends in April 2027, the penalty regime is:

Late submission penalties

• Each late quarterly update earns one penalty point
• At 4 points (quarterly reporters), you receive a £200 penalty
• Every subsequent late submission incurs another £200
• Points expire after 24 months of on-time submissions

Late payment penalties

Late payment penalties are separate and apply from year one (no grace period for payments):

• 15 days overdue: penalty accrues at 2% annualised
• 30 days overdue: additional 2% charge on the outstanding amount
• After 30 days: 4% annualised on the remaining balance

This is on top of HMRC's standard late payment interest, which is currently around 7.5%.

The realistic risk

For the 2026/27 tax year, the submission risk is minimal thanks to the grace period. But do not confuse submission penalties with payment penalties. If you owe tax and pay late, that costs you money from day one regardless of MTD.

Frequently Asked Questions

Does Making Tax Digital affect my limited company?

No. MTD for Income Tax applies to personal income reported on Self Assessment — primarily self-employment and property income. Your limited company's Corporation Tax filing is not affected. MTD for Corporation Tax has no confirmed start date. However, if you personally earn rental or freelance income above the threshold alongside your company income, your personal tax reporting is in scope.

What if my income fluctuates around the £50,000 threshold?

HMRC uses the most recent tax year data to determine eligibility. If your gross qualifying income was above £50,000 in 2024/25, you are in scope from April 2026 even if it drops below £50,000 in 2025/26. Once mandated, you generally remain in the system. If your income consistently falls below the threshold, you can apply to leave MTD, but the process is not automatic.

Can I still use spreadsheets?

Not on their own. You can use spreadsheets for your day-to-day record-keeping if you also use bridging software to submit the data to HMRC digitally. The bridging software reads your spreadsheet and transmits the figures via the MTD API. However, HMRC prefers full digital record-keeping, and bridging software adds an extra layer of complexity and cost.

Are quarterly updates the same as filing four tax returns a year?

No. Quarterly updates are much simpler. You are submitting a summary of income and expenses for the quarter — not calculating tax, claiming reliefs, or completing a full return. The detailed tax calculation happens once a year in the Final Declaration. Think of quarterly updates as progress reports.

What happens during the first-year grace period?

HMRC has confirmed that no penalty points will accumulate for late quarterly submissions between April 2026 and April 2027. You will not receive financial penalties for late quarterly updates during this period. However, you are still legally required to submit. The grace period is a soft landing to help people adjust, not an exemption. Late payment penalties and interest still apply if you owe tax and pay late.

I already use MTD for VAT. Do I need to do anything extra?

Yes. MTD for VAT and MTD for Income Tax are separate obligations using different HMRC APIs. Your VAT software may or may not support Income Tax MTD. Check with your provider. You may need to enable additional features, upgrade your plan, or use a different tool for Income Tax quarterly updates. Do not assume that VAT compliance means you are automatically covered for Income Tax.

The Bottom Line

MTD for Income Tax is not optional, and it is not getting delayed again. If you have self-employment or property income over £50,000, you have roughly seven weeks to get ready.

The good news: quarterly updates are simpler than most people fear, the first year has no submission penalties, and there are plenty of software options at every price point. The biggest risk is not the reporting itself — it is leaving preparation until the last minute.

Pick your software, set up your records, register with HMRC, and get on with running your business. The sooner you start, the less painful the transition will be.
