MTD support for limited company web designers: what it actually means
If you run a web design business through a limited company, you’re probably juggling client work, proposals, retainers, software subscriptions, and the occasional “can you just…” request that turns into a full rebuild.
Making Tax Digital (MTD) is one of those compliance changes that can feel like background noise—until a deadline lands and you’re not quite sure whether you’re doing things the way HMRC expects.
This post explains what MTD support is, how it affects most limited company web designers (usually through VAT), and what good support looks like in practice—so you feel clear, organised, and in control.
Quick refresher: what is Making Tax Digital?
Making Tax Digital is HMRC’s move towards digital record keeping and digital filing. The aim is to reduce errors and make tax reporting more consistent.
For most limited companies in the web design world, the key part right now is:
- MTD for VAT – keeping VAT records digitally and submitting VAT Returns to HMRC using MTD-compatible software.
Other parts of MTD (such as MTD for Income Tax) generally affect sole traders and landlords, rather than limited companies. Corporation Tax is expected to become more digital over time, but VAT is where most limited companies feel MTD today.
Does MTD apply to your limited company web design business?
MTD for VAT applies if your company is VAT registered (including voluntary VAT registration). If you’re VAT registered, you must:
- Keep certain VAT records digitally
- Submit VAT Returns through MTD-compatible software
- Use digital links where required (more on this below)
If you’re not VAT registered, you may not be in MTD yet—but it’s still worth setting your bookkeeping up properly now. It’s much easier to build good habits early than to fix messy records later.
Why web designers often find VAT and MTD fiddly
Web design businesses are usually straightforward in terms of day-to-day transactions, but there are a few common pressure points:
- Mixed income types: projects, retainers, maintenance, hosting recharges, consulting
- Timing differences: deposits, staged payments, and final invoices
- Overseas clients: services supplied to the EU/US and the VAT treatment not always being obvious
- Software subscriptions: lots of small monthly costs (Adobe, Figma, hosting, stock libraries) that need consistent VAT treatment
- Working with subcontractors: UK vs overseas contractors, and ensuring invoices are valid for VAT
MTD doesn’t change what VAT you owe—but it does change how you must record and submit the information. That’s where proper support saves time and reduces stress.
What HMRC expects under MTD for VAT (plain English)
To stay compliant, HMRC expects you to:
- Keep VAT records digitally (usually in accounting software)
- Submit your VAT Return digitally via MTD-compatible software (not by typing numbers into HMRC’s old portal)
- Maintain digital links between systems where relevant (so figures aren’t repeatedly copied and pasted)
What are “digital links”?
A digital link is simply an electronic transfer of data between pieces of software or spreadsheets—rather than manually retyping figures.
For many small limited companies, the simplest approach is to keep everything in one system (for example, Xero or QuickBooks). If you rely heavily on spreadsheets, we’ll help you set this up properly so it still meets the rules.
What good MTD support looks like for a limited company web designer
MTD support shouldn’t just mean “we file the VAT Return”. It should mean you can run your business knowing the numbers are accurate, deadlines are met, and nothing is quietly building up in the background.
Here’s what we typically focus on when supporting limited company web designers:
1) Getting your software set up properly
We’ll help you choose and configure an MTD-friendly setup that fits how you work. That often includes:
- Xero or QuickBooks configuration
- Correct VAT settings (standard, cash accounting if relevant, flat rate if relevant)
- Invoice templates, payment terms, and branding
- Bank feeds and rules to reduce admin
The goal is simple: your day-to-day bookkeeping should feel light, not like a second job.
2) Making sure your VAT treatment is correct
For web designers, the biggest VAT mistakes usually come from:
- Incorrect VAT codes on software subscriptions
- Overseas sales being treated like UK sales (or vice versa)
- Missing VAT invoices for costs
- Confusion over what date VAT should be accounted for (invoice date vs payment date)
We’ll review your bookkeeping and make sure your VAT Return reflects reality—not a best guess at 10pm on deadline day.
3) Keeping your records tidy (so VAT Returns are easy)
MTD is much smoother when your records are kept up to date. We support you with:
- Monthly or quarterly bookkeeping checks
- Chasing missing receipts and invoices (before it becomes a problem)
- Reconciling bank, Stripe/PayPal, and card transactions
- Making sure director expenses and reimbursements are recorded correctly
4) Submitting VAT Returns on time, every time
VAT deadlines are firm. Late filing or late payment can trigger penalties and unwanted HMRC attention.
With proper MTD support, you should always know:
- When your VAT Return period ends
- When the submission deadline is
- How much VAT is due (with enough notice to plan cashflow)
5) Helping you understand the numbers (without drowning you in reports)
You don’t need a 20-page pack of charts. You do need clarity.
We’ll help you understand:
- Whether you’re setting aside enough for VAT
- How retainers and deposits affect VAT timing
- Whether your pricing still works once VAT is considered
Common questions we hear from limited company web designers
“I use spreadsheets—can I stay on spreadsheets under MTD?”
Sometimes, yes—but it must be done carefully. You’ll still need an MTD-compliant way to submit the VAT Return, and you may need to ensure the data flows via digital links.
In practice, most web designers find it easier (and less stressful) to move to Xero or QuickBooks, especially once you factor in bank feeds and automation.
“Do I need to sign up for MTD?”
If your company is VAT registered, you’ll normally need to be set up for MTD for VAT. Most businesses are already within MTD, but if you’re newly VAT registered or changing systems, it’s worth checking everything is connected properly.
“Will MTD increase my tax?”
No—MTD is about how you keep records and submit returns, not increasing the rates. But it does mean errors are more likely to be spotted, so it’s important to get the basics right.
A simple MTD checklist for web design limited companies
- Use MTD-compatible accounting software (or a compliant spreadsheet + bridging solution)
- Keep invoices and bills recorded digitally
- Reconcile bank and payment platforms regularly
- Check VAT codes on subscriptions and overseas transactions
- Know your VAT deadlines and set aside funds for payment
