Over £50,000 as a Contractor? You’re Already Inside Making Tax Digital

If you work as a contractor and your gross income from self-employment and property exceeded £50,000 in the 2024/25 tax year, Making Tax Digital for Income Tax is not something coming in the future. It started on 6 April 2026 and you are already in it. Your first quarterly update deadline is 7 August 2026, covering the standard update period from 6 April to 5 July 2026. If you have not yet set up MTD-compatible software, signed up with HMRC, or spoken to your accountant about what this means for you, then this article is exactly what you need to read right now.

Why Contractors Are Often Caught Off Guard by MTD

The confusion around MTD and contractors largely comes down to structure. MTD for Income Tax applies to individuals with qualifying income from self-employment and property. For contractors, this becomes relevant if you trade as a sole trader, have separate freelance income outside a limited company, or receive property income.

MTD for Income Tax applies to sole traders and landlords registered for Self Assessment when their qualifying income is above the relevant threshold. Limited company income is not counted for MTD for Income Tax, and partnerships are not yet within the main MTD for Income Tax timetable. However, your share of partnership profit must still be reported in your tax return through compatible software if you are already in MTD because of other qualifying income.

So the key question is not simply how much you earn. It is how you earn it. If you operate as a sole trader, either exclusively or alongside other income sources, and your gross qualifying income from self-employment and property combined exceeded £50,000 in the 2024/25 tax year, your MTD obligations began on 6 April 2026.

Many contractors who operate through a limited company for their main contracting work also have sole trader income on the side, whether from consulting, freelance projects, or property rental. Only income from self-employment trades and property businesses is counted towards the threshold. Employment income taxed through PAYE, pension income, savings interest, dividends and capital gains are excluded. But if your qualifying income from self-employed or property streams alone takes you over £50,000, MTD applies.

What Counts as Qualifying Income for a Contractor?

This is where a lot of contractors get caught out. Qualifying income is your gross income from self-employment and property before expenses or deductions are taken off. It is not your profit. For example, if you are a self-employed contractor with turnover of £55,000 but expenses of £20,000, your qualifying income is £55,000, not your £35,000 profit. You would therefore fall into Phase 1 from April 2026.

The distinction between gross income and profit is critical. Many contractors whose businesses involve significant costs, whether materials, subcontractors, equipment or professional fees, assume their net position is what HMRC uses to assess their MTD obligations. It is not. The threshold is based on gross income before you deduct business expenses.

Qualifying income is the gross turnover from your sole-trade business plus gross property income that counts for Self Assessment. For UK tax residents, this can include UK and foreign property income declared through Self Assessment. It does not include employment income, dividends, savings interest, pension income, capital gains, or your share of profit from a partnership as an individual partner.

Here is how this plays out in practice for different contractor types:

Contractor type	Income sources	Qualifying income	In MTD from April 2026?
Sole trader contractor, £60k turnover	Self-employment only	£60,000	Yes
Limited company contractor, £80k salary/dividends	Employment/dividends only	£0 qualifying	No
Limited company contractor + £55k sole trader side work	Company income + self-employment	£55,000	Yes
Sole trader, £40k trade + £15k rental income	Self-employment + property	£55,000	Yes
Sole trader, £30k trade + £15k rental income	Self-employment + property	£45,000	No for April 2026, but likely Phase 2 from April 2027 if 2025/26 qualifying income is over £30,000
CIS sole trader subcontractor, £52k gross	Self-employment	£52,000	Yes

HMRC determines your Phase 1 threshold based on the income reported on your 2024/25 Self Assessment tax return, which was due by 31 January 2026. If that return showed qualifying income above £50,000, you are in scope and the obligation is live now.

What About CIS Contractors and Subcontractors?

Construction Industry Scheme contractors and subcontractors are a group that frequently underestimate their MTD exposure, and it is worth addressing this directly.

MTD applies to CIS subcontractors who are sole traders with gross qualifying income above £50,000 from 6 April 2026. The threshold then drops to £30,000 from April 2027 and £20,000 from April 2028. Qualifying income is your gross turnover before expenses, and CIS deductions made by your contractor do not reduce this figure.

This last point is particularly important. If you are a CIS subcontractor and your contractor deducts 20% from your payments before passing them to you, your qualifying income for MTD purposes is still the gross amount before those deductions. So if you invoice £60,000 and receive £48,000 after CIS deductions, your qualifying income is £60,000, not £48,000.

For CIS subcontractors who are already used to the deduction and reclaim process at Self Assessment time, this is a familiar concept. But for MTD, it means the threshold catches more people than they might initially expect when looking only at what actually lands in their bank account.

If you work in construction as a sole trader and want to understand how CIS interacts with your wider compliance obligations, our post on understanding the importance of CIS registration is worth reading alongside this guide. Our CIS for contractors checklist also covers the practical steps in managing your CIS obligations correctly.

What If You Work Through a Limited Company and Also Have Sole Trader Income?

This is a situation many contractors find themselves in, and the MTD implications can be surprisingly easy to miss.

IR35, or the off-payroll working rules, applies where a worker provides services through an intermediary, such as a personal service company. Those rules are separate from MTD for Income Tax. Limited company income, salary and dividends are not qualifying income for MTD for Income Tax.

However, if you also take on separate sole trader work, consulting projects, freelance assignments, or rental property income, those income streams may count. If your qualifying income from those sources exceeded £50,000 in 2024/25, you need to comply with MTD from 6 April 2026, even if your main contracting income still comes through a limited company.

The point about staying in MTD once you are over the threshold is important. Once you start using MTD and your qualifying income later drops below the relevant threshold, you can only choose to opt out after your qualifying income has been below the threshold for 3 tax years in a row.

This means that even if your 2025/26 income drops significantly below £50,000 because you moved back to company-only work or reduced your sole trader activity, you do not automatically exit MTD straight away. Getting proper advice from contractor accountants who understand both contractor tax structures and MTD requirements is the most practical way to navigate this.

The 5 Things You Need to Have in Place Right Now

If you are a contractor caught by Phase 1 and you have not yet set up your MTD compliance, here is what needs to happen before 7 August 2026.

First, you need to confirm your qualifying income from your 2024/25 Self Assessment return. Add your gross self-employment turnover and your gross property income together. If the combined figure exceeds £50,000, you are in scope.

Second, you need to choose and set up MTD-compatible software. This must be HMRC-recognised software capable of keeping digital records and submitting quarterly updates to HMRC. Spreadsheets can only be used if they are connected through compatible bridging software. A spreadsheet on its own is not enough to submit MTD updates. At Asmat & Co we use QuickBooks, and as certified QuickBooks accountants we can get your account set up and connected to HMRC quickly.

Third, you need to sign up for MTD for Income Tax through HMRC’s online service and link your software to your HMRC account. Having the software installed is not the same as being signed up. The registration and authorisation step must be completed before you can submit.

Fourth, you need to make sure your digital records cover the period from 6 April 2026 onwards. If your bookkeeping has slipped since April, you need to catch up now. The first quarterly update covers the standard period from 6 April to 5 July 2026, and your records need to be in shape to support that summary.

Fifth, if you are authorising an accountant to act as your MTD agent, that authorisation needs to be set up correctly. Once in place, your accountant can help manage your quarterly updates and your end-of-year tax return through compatible software.

If any of these steps are not yet done, the time to act is now, not the week before 7 August. Working with accountants for sole traders who are already operating in the MTD environment means you can get all of this sorted quickly and with confidence.

What Your Quarterly Submission Actually Involves

At its core, MTD for Income Tax is about digital record-keeping and more frequent reporting. Instead of keeping manual records and submitting a single annual Self Assessment return, taxpayers maintain digital records and send quarterly updates to HMRC.

The first quarterly update covering 6 April to 5 July 2026 is a categorised summary of your business income and allowable expenses for that period. It is not a detailed transaction list. It is not a tax calculation. And quarterly reporting does not mean quarterly tax payments. Tax is still paid under the existing January timetable.

For contractors, the categories of expenses you report are the same broad Self Assessment categories you have always used: professional fees, equipment, travel and mileage, home office costs, insurance, software subscriptions, training, and other costs wholly and exclusively incurred for the purposes of your business.

The difference is that you are now reporting through digital software during the year rather than pulling everything together at the end of the year. For contractors with a clean dedicated business bank account and well-maintained records, this is a manageable change in frequency. For those whose records have historically been assembled at year-end from memory and a folder of receipts, it requires a genuine change in habits.

Our post on self-assessment for sole traders gives useful context on how the transition from annual to quarterly reporting changes your relationship with HMRC throughout the year.

The Soft Landing and What It Actually Means for Contractors

HMRC has confirmed a soft landing for the 2026/27 tax year, meaning no penalty points will be issued for late quarterly updates during this first year. For contractors who are scrambling to get set up, this is a genuine and meaningful concession.

However, quarterly updates remain a legal requirement, meaning digital record-keeping still applies. You still need to send your quarterly updates before you can submit your tax return through compatible software, so the soft landing does not mean MTD can be ignored until 2027.

The soft landing also does not protect you from penalties for a late tax return or late payment of tax. These still apply.

The most practical way to think about the soft landing is this: it removes the immediate penalty point risk for late quarterly updates in 2026/27, but it does not make the submissions optional. From the 2027/28 tax year onwards, the full points-based late submission regime applies to quarterly updates. Four penalty points can trigger a £200 penalty, with further £200 penalties for later missed deadlines once the threshold has been reached.

How MTD Interacts with Your Self Assessment for 2025/26

Contractors in Phase 1 still have a traditional Self Assessment return to file for the 2025/26 tax year, covering the period that ended on 5 April 2026. This return is due by 31 January 2027 and covers the year before MTD went live.

This means that in the coming months, Phase 1 contractors are simultaneously managing their first year of MTD quarterly updates for 2026/27 and preparing their traditional Self Assessment return for 2025/26. Running both processes in parallel, one new and one familiar, is one of the practical challenges of this transition year.

If your accountant for tax return is already handling your Self Assessment, make sure they are also set up for MTD and that both obligations are being managed together. Having 2 different people handling 2 different parts of your tax affairs increases the risk that something falls through the cracks.

At Asmat & Co, we manage both the traditional Self Assessment return for 2025/26 and the MTD quarterly updates for 2026/27 for our contractor clients, giving you a single point of contact for your entire tax position.

VAT-Registered Contractors: You Are Already in MTD

If you are a VAT-registered sole trader contractor, you are already familiar with one dimension of Making Tax Digital. MTD for VAT has been mandatory for all VAT-registered businesses since April 2022, requiring digital record-keeping and VAT return submission through compatible software.

As of 2026, those VAT rules still apply. This means that if you are a VAT-registered contractor, you must continue complying with MTD for VAT as you have already been doing. What changes in 2026 is that your MTD obligations may now extend to Income Tax as well, adding quarterly income tax updates on top of your existing VAT return cycle.

For VAT-registered contractors already using QuickBooks or another compatible platform for VAT returns, extending that same platform to cover MTD for Income Tax should be more straightforward than starting from scratch. Your software may already be in place, your bank feeds may already be connected, and the quarterly rhythm may already feel familiar. The key additional step is signing up separately for MTD for Income Tax and ensuring your software is configured to submit income tax updates as well as VAT returns.

Our VAT return accountant service manages your VAT compliance as part of the same overall package, so the 2 streams of MTD compliance are handled consistently and without duplication. You can also read more about VAT compliance for contractors in our post on how VAT registration can affect your price and our MTD for VAT guide.

Record-Keeping for Contractors Under MTD

The record-keeping requirement under MTD is more demanding than what many contractors have previously maintained for Self Assessment. Under the old system, it was possible to reconstruct a year’s records from bank statements and invoices at year-end. Under MTD, your records need to be maintained digitally throughout the year so that your quarterly updates are accurate and ready by the deadline.

For most contractors, the practical answer is a dedicated business bank account connected via a live bank feed to MTD-compatible software. Every transaction that flows through the account is imported automatically, assigned to the correct category, and available for review at any time. The quarterly update is then a matter of reviewing the categorised transactions, checking for anything that needs adjustment, and submitting through the software.

If you have multiple sources of qualifying income, you may need to submit separate quarterly updates for each one. If you have 2 sole trades and a UK property business, you will usually submit 12 quarterly updates per year, 4 per income source, before submitting your tax return through compatible software. This is worth knowing upfront, as it affects how your software needs to be set up from the outset.

Using payroll accountant services alongside your MTD bookkeeping can also help if your contractor business employs staff or has payroll costs, because those costs need to be recorded accurately and kept separate from non-qualifying personal income.

Planning Your Finances as a Contractor Under MTD

One of the benefits that MTD brings, if you approach it positively, is better visibility of your financial position throughout the year. Rather than discovering your tax position in January when your accountant finalises your return, you have a running picture of your income and expenses that allows you to plan ahead.

For contractors whose income fluctuates between contracts, this real-time visibility is genuinely useful. You can see when a quiet period is affecting your quarterly income, plan your expenditure accordingly, and set aside tax provisions more accurately because you are not working from figures that are several months old.

Our financial reporting services sit alongside your MTD compliance to give you a fuller picture of your business performance, not just the HMRC-facing summaries but the management information you need to make good decisions about pricing, expenditure, and growth. You can read more about how this works in practice in our post on how online accountants use management reports.

For contractors thinking about whether their current structure, sole trader, limited company, or a mix of both, still makes sense in the post-MTD environment, our post on sole trader to limited company is worth reading. The tax and compliance implications of each structure are significant, and the right choice depends on your specific income level, working arrangements, and longer-term plans.

Frequently Asked Questions

I operate through a limited company. Does MTD for Income Tax apply to me?

Not for income earned through the limited company. Limited companies are not within MTD for Income Tax, and there is no Making Tax Digital for Corporation Tax mandate for 2026. However, if you also have sole trader income or property income outside the limited company that takes your qualifying income above £50,000, those streams are caught by MTD even if your company income is not.

My gross turnover is over £50,000 but my profit after expenses is much lower. Am I still in scope?

Yes. It is gross income that counts, not profit after expenses. If your gross self-employment turnover and property income exceed £50,000 for the 2024/25 tax year, you are in Phase 1 regardless of what your profit is after deducting your costs.

I was over £50,000 in 2024/25 but my income has dropped significantly this year. Can I exit MTD?

Not immediately. Once you start using MTD and your qualifying income later drops below the relevant threshold, you can choose to opt out only after your qualifying income has been below the threshold for 3 tax years in a row. If all your self-employment and property income sources have ceased, you should tell HMRC because different treatment may apply.

Does the 7 August 2026 deadline apply even if I have only just found out I am in scope?

Yes. The obligation applies from 6 April 2026 based on your 2024/25 qualifying income. Not receiving a letter from HMRC does not create an exemption. The responsibility to check your scope and comply rests with you. If you act now, there is still time to get signed up, set up your software, and catch up your records before 7 August.

What happens to my January 2027 Self Assessment deadline?

Your traditional Self Assessment return for the 2025/26 tax year, the year that ended on 5 April 2026, is still due by 31 January 2027. This runs in parallel with your MTD obligations for 2026/27. For the 2026/27 tax year, you will submit your tax return through MTD-compatible software by 31 January 2028.

Can I use the same software for both MTD for VAT and MTD for Income Tax?

Yes, if you use a platform like QuickBooks that handles both. A single platform that covers your VAT returns, income tax quarterly updates and bookkeeping is significantly more efficient than using separate tools for different compliance obligations, and it reduces the risk of discrepancies between figures in different submissions.

Act Now Before 7 August

The 7 August deadline is close. If you are a contractor with qualifying sole trader or property income above £50,000 and you are not yet set up for MTD, the window to get this right before the first deadline is narrow but still open. Getting your software in place, your records in order, and your accountant authorised takes time, so it is better to act now rather than wait until the deadline is almost here.

At Asmat & Co, we are ready to help you get compliant quickly and stay compliant throughout the year. One conversation is all it takes to get started.
