Making Tax Digital (MTD) trips people up because it has rolled out in phases, and the wording from HMRC can sound more technical than it actually is. We hear the same misunderstandings again and again from decent, organised business owners who are just trying to get on with work. So this is a simple myth-busting guide to the seven big ones, with the plain-English reality underneath. A lot depends on what you do and how you’re set up – sole trader, landlord, partnership, or limited company – so think of this as a clear starting point rather than a one-size-fits-all rulebook.
This myth is very common, and to be honest it makes sense. For many small businesses, the first time they heard “Making Tax Digital” was when they had to start filing VAT returns through compatible software. So MTD ends up feeling like a VAT-only admin change.
But MTD is really a wider HMRC programme, and VAT is just one part of it. There are two flavours most small business owners bump into:
MTD for VAT is about how you keep VAT records and how you submit VAT returns. If you’re VAT registered, this is the bit you might already be doing.
MTD for Income Tax is separate. You’ll often see it called MTD ITSA, which is short for Making Tax Digital for Income Tax Self Assessment. That one is aimed at people who pay Income Tax on business or property income, so mainly sole traders and landlords.
A quick real-world example. A VAT-registered builder in London is probably already doing MTD for VAT, because their VAT returns have to go in via software. That same builder might also be affected by MTD for Income Tax in future if they’re trading as a sole trader (not a limited company) and meet the criteria when it applies to them.
Now take a non-VAT Etsy seller. They might think MTD has nothing to do with them, because they don’t charge VAT and don’t file VAT returns. But MTD can still become relevant through the Income Tax side, because Etsy income is still income and HMRC still expects it to be declared if you’re over the usual reporting limits.
The practical point is this: the rules change depending on which tax you’re dealing with. VAT rules are one set. Income Tax rules are another. If you’re not sure which bucket you’re in, it’s worth getting that clear early. In practice, that one decision drives everything else, including what records you need to keep and what software (if any) you actually need to use.
This one catches a lot of sensible business owners out because profit is what matters day to day. It is what pays the mortgage. But for Making Tax Digital for Income Tax, the trigger is based on gross income, not profit.
Turnover (also called gross income) is the total money you invoice or receive from sales, before expenses. Profit is what’s left after you subtract your costs like materials, fuel, software, and subcontractors.
In practice, you can have a low-profit year and still be over the line. Think of a contractor who invoices a decent amount over the year, but has high costs. Maybe they are paying for tools, van repairs, and a lot of materials, or they are paying subcontractors on a job. The profit might look modest once everything is deducted, but the turnover can still be high enough to bring MTD into play under the current rules. If you are anywhere near it, check the latest HMRC guidance rather than guessing.
The same idea applies to landlords. It is the rental income coming in, not what’s left after agent fees, repairs, and mortgage interest restrictions.
One practical tip: don’t just look at your tax bill and assume that tells you anything about MTD. Look at your total business and/or property income for the year. That is the number that matters for whether you are in scope, even if your final tax due is small.
Spreadsheets are not the enemy. A lot of organised business owners use Excel or Google Sheets and do perfectly good tracking. The catch is that Making Tax Digital is not just about keeping your own records. It is also about how those records get from your file to HMRC.
When HMRC says “digital records”, think: you keep the key details in a digital form, not on scraps of paper or only on bank statements. For most people that means dates, amounts, and what the transaction was for, logged as you go. A spreadsheet can count as digital records for that part, in practice.
“Digital links” is the bit people miss. It just means the numbers move between systems without you retyping them. So if you copy and paste totals from your spreadsheet into a portal, or type them into software by hand, that is the sort of gap MTD is trying to remove. Not because HMRC loves tech. More because manual rekeying is where mistakes creep in.
The reality for lots of small businesses is simple: they keep the spreadsheet, then use either bridging software or accounting software to do the submission. Bridging software is basically a tool that takes the totals from your spreadsheet and submits them through an MTD-compatible connection. Accounting software does the same job, but the records usually sit inside it rather than in Excel.
Here is a very normal example. A landlord tracks rent, service charges, repairs, and agent fees in Excel. At the moment they might total it up once a year and pass it to their accountant, or type it into their tax return. Under MTD for Income Tax, they would still be able to track in Excel, but they would need a way to send the required updates from that spreadsheet through compatible software, with a clean digital link. For most people that means setting the spreadsheet up to feed into bridging software, or switching to software that keeps the records and submits from the same place.
If you are already disciplined with your spreadsheet, I would not rush to throw it away. The judgement call is whether your spreadsheet is actually reliable month to month, or whether it only makes sense once you have had a quiet Sunday and three cups of tea. If it is the second one, proper software can be less stressful, not more.
This is the one that makes people panic. The idea of doing a full tax return four times a year sounds brutal. In practice, that is not what Making Tax Digital for Income Tax is aiming for.
The simple split is this: quarterly updates versus the year-end finalisation. The quarterly updates are regular summaries of what is coming in and going out. The year-end finalisation is when you do the proper tidy-up, apply the rules, and confirm the final figures. You will also make an end-of-year declaration, which is basically you signing off that the information is complete and correct.
Quarterly usually means totals. Income totals. Expense totals. Not a full tax computation with every adjustment and relief worked out. Things like capital allowances (the tax way of claiming for equipment over time) and more fiddly adjustments are typically a year-end job, when you have the full picture.
Here is a normal example. A sole trader invoices monthly, say a plumber or a freelance designer. Money comes in at odd times because some clients pay late. Expenses are the same. Fuel might be weekly, tools might be a big hit one month, and insurance might be annual. A quarterly update in that situation can be a rough estimate of how the year is going so far. It is not a moment where you stop everything and do a mini self assessment from scratch.
What quarterly looks like in real life is closer to keeping your books up to date, then sending a summary. You are not expected to have every last detail perfectly finalised every three months. You are trying to keep the records current enough that the totals make sense and you are not rebuilding the whole year from a shoebox in January.
Practical advice: if your numbers swing around a lot, do not obsess over making each quarterly update “perfect”. Focus on being consistent with what you record and when. The judgement call is whether you can stay on top of it with a simple system, or whether you need something a bit more structured so you are not constantly catching up.
Look, this one catches people out because we use the word “business” for everything. HMRC does not. In tax terms, being self-employed and running a limited company are different beasts.
If you are self-employed, you and the business are basically the same for tax. The profit is your personal income, and it goes on your self-assessment tax return.
If you run a limited company, the company is a separate legal person. The company earns the income and pays its own tax. You then pay personal tax on what you take out, usually through salary and dividends.
That is why corporation tax is a separate system. The company’s corporation tax return is the CT600 (it tells HMRC the company’s taxable profit and tax due). It is not part of your self-assessment, even if the same accountant does both.
MTD for Income Tax is aimed at individuals, mainly sole traders and landlords. It is about digital records and updates for your personal business income. Limited companies can be affected by Making Tax Digital in other areas, but it is not a copy-and-paste of the sole trader rules.
A real example we see: a small marketing agency incorporates last year. Before incorporation, the owner was self-employed, invoicing clients and putting the profit on their self-assessment. After incorporating, the invoices are in the company name, the bank account is the company’s, and the year-end work changes. You are now looking at company accounts and a CT600 for the company, plus a personal tax return for the director if they take salary or dividends. Same clients, similar work, different obligations.
Practical advice: be clear what you actually are right now, not what you “feel like”. Check whose name is on the invoices and who owns the bank account the income lands in. If it is the limited company, do not assume MTD for Income Tax will cover it just because you are the only person in the business.
The judgement call is this: if you have recently incorporated, or you are half-and-half (some income personally, some through a company), get it mapped out early. In practice, the confusion usually comes from mixing records, and that is what creates late filings and messy clean-ups later on.
I get why this myth sticks. People assume HMRC will tap them on the shoulder when it matters. In practice, letters can arrive late, go to an old address, or look like generic “HMRC speak” that is easy to ignore. Emails can get missed too, especially if they go to an inbox you do not check, or they land in junk.
The other thing is timing. Even if you do get a letter, it might not give you much breathing room. Making Tax Digital is not just a box you tick. It usually means changing how you keep records day to day, and sometimes changing what software you use. Those habits take a bit of time to bed in.
A simple example we see a lot: someone sells on Etsy or Vinted on the side, or does Uber Eats at weekends. It starts small, then it grows. They have never registered for self-assessment (that is the yearly tax return individuals file for extra income). They assume HMRC will prompt them when it becomes “proper money”. Often, nothing prompts them, and they are left trying to rebuild a year of sales and costs from app screenshots and scattered bank payments.
What to do early, without panicking. First, be clear what you are. Are you a sole trader, a landlord, in a partnership, or running everything through a limited company. Second, list your income sources. Not just the main one. Include side hustles, online platforms, cash jobs, rent, and any contracting work. Third, look honestly at your records. Are you keeping invoices and receipts as you go, or is it a pile of emails and a bank feed you promise yourself you will sort later.
Then make one small judgement call. If your income streams are simple and you are already keeping tidy records, you can probably adjust with minimal fuss. If things are mixed, you have multiple platforms, or you are not sure what counts as business income, plan ahead and get clarity sooner rather than later. Not to register blindly, but to work out what actually applies to you and what needs changing.
Basically, do not outsource awareness to the post. Keep your contact details up to date, yes, but also take ownership of your position. It makes the whole MTD transition calmer, and you are not trying to overhaul your record-keeping in a rush.
This one is really common. And to be fair, it sounds logical. You pay an accountant, so surely they deal with Making Tax Digital and you get on with work.
The reality is more split than that. An accountant can handle the submissions, deal with HMRC, and make sure the numbers are pulled together properly. But we cannot guess your income or recreate your expenses from thin air. You still need to capture what is coming in and what is going out, in a way that is complete and not a last-minute scramble.
MTD is as much about the process as the filing. In practice, what changes for most people is this: you keep records digitally as you go, you send information more often, and there are fewer shoebox-of-receipts moments in January. That does not mean you are doing “accounting”. It means you are keeping the raw ingredients in a usable shape.
A simple example. A CIS subcontractor in construction might have a steady stream of small costs: screws and fixings, blades, PPE, parking, fuel, trade counter runs, and the odd tool that breaks mid-job. CIS means tax is taken off your labour pay by the contractor, before you get paid. If those expenses are only gathered once a year, you usually miss some, and it becomes a stressy guessing game. If you keep up monthly, even just snapping receipts and noting what they were for, it is calmer. It also helps your accountant make sure you are claiming what you are entitled to, not just what you can still find.
So what should you actually do? Pick one method you can stick to. Maybe it is an app, maybe it is bookkeeping software, maybe it is a spreadsheet that you update weekly alongside a folder of digital receipts. The key is that it is regular and backed up with proof of the costs. Bank statements help, but they do not explain what the payment was for, and HMRC can ask for evidence.
The small judgement call is about rhythm. If you have lots of small transactions, mixed income streams, or you are often busy on site and forgetful with paperwork, go monthly. It saves you time overall. If your business is genuinely simple and low-volume, you might get away with a less frequent routine, but it still needs to be consistent.
Basically, an MTD accountant can press submit. They can also sanity-check, tidy up, and keep you compliant. But MTD works best when you have a workable habit for capturing income and expenses, so the numbers are there when they are needed.
We often see the same pattern with Making Tax Digital. People get half the picture, then build a plan around it, and it falls over later. A common problem is leaving the setup until the last minute because it feels like paperwork, then realising the digital link is the bit that matters in practice.
If you are unsure whether you are in scope, treat it like a yes until you have properly checked, because waiting for HMRC to contact you is rarely the least stressful route. Getting your records into a habit early is usually the difference between a calm quarter and a weekend spent trying to rebuild months from bank statements.
If all of this still feels a bit much, or you just want someone to look at your numbers and tell you straight whether you need to worry about it – that’s literally what we do.
We handle the whole Making Tax Digital process for self-employed people and landlords.
Registration with HMRC, setting up your records (QuickBooks or a spreadsheet – either works), quarterly submissions, the end of year stuff, all of it. You don’t need to learn the system yourself.
