UK VAT return deadlines: How to file on time & avoid penalties
Your company may have to pay hundreds of pounds in fines and interest if you miss the deadline for filing your VAT return. Inaccurate or delayed submissions also put your company on HMRC's radar, which makes compliance more challenging in the future. You can keep on top of your VAT obligations and reduce stress by knowing your deadlines, staying organised, and using the right tools.

Why VAT return deadlines are important
HMRC sets strict deadlines for VAT returns. If you miss a deadline or submit the wrong information, you risk:
- Penalty points and fines
- Interest on late payments
- Increased scrutiny from HMRC
Even a single missed submission counts against your compliance record. Businesses that regularly miss deadlines face larger fines and may appear high-risk to HMRC. Staying on top of deadlines protects your business from extra costs and future audits.
How HMRC penalties works
HMRC uses a points-based system for late VAT returns. Each late submission adds points:
- One late submission = one penalty point
- Quarterly filers get a £200 fine after four points
- Monthly filers reach the threshold at five points
- Annual filers reach it at two points
Points only reset after a compliance period of timely submissions, often 12 months or more. A single missed deadline can affect your compliance record for the following year.

Common mistakes that lead to late VAT filing
Most penalties happen because of simple errors, not fraud:
- Forgetting the submission date
- Assuming weekends or bank holidays move deadlines
- Relying only on email reminders
- Sending documents to accountants too late
- Using outdated, non-MTD-compliant systems
When managing clients, payroll, inventory, and invoicing, these mistakes are common. A minor error could lead to penalties and increase the pressure on the following submissions.
Tracking your VAT return deadlines
To avoid fines, you need to monitor deadlines carefully. Steps to do this include:
- Set digital reminders at least a week before the deadline
- For precise submission dates, visit HMRC’s website.
- Maintain a shared calendar for VAT returns.
- To reduce mistakes, double-check using accounting software.
Proactive tracking ensures enough time to review, fix mistakes, and submit on time.

Frequently Asked Questions:
Your Questions – Answered ,We’re here to help you with anything VAT-related.
1. What is the VAT return deadline in the UK?
In the UK, most VAT returns are due one month and seven days after the end of your accounting period. So, if your VAT quarter ends on 31 March, you’ll need to file and pay by 7 May. The exact date depends on how often you file—monthly, quarterly, or yearly—so it’s best to double-check your HMRC account.
It’s always safer to submit early rather than wait until the last day. Sometimes payments take a bit longer to process, and the HMRC system can get busy close to deadlines. Using MTD-approved software keeps things simple, as it connects directly to HMRC and helps avoid filing mistakes.Using Making Tax Digital (MTD) software ensures your return is sent directly to HMRC without mistakes or delays. Setting calendar reminders and reviewing VAT figures early also helps you avoid last-minute errors or missed submissions.
2. What happens if you miss your VAT return deadline?
If you miss your VAT return deadline, HMRC gives you one penalty point for each late submission. Once you reach a certain number of points—usually four for quarterly returns—you’ll be fined £200. Every late return after that adds another £200 fine until you build a clean record again.
HMRC may also charge interest on late VAT payments, which can add up over time. Repeatedly missing deadlines could make HMRC more cautious about your business and increase the risk of an audit.
If you realise you’ve missed the date, don’t wait—file and pay as soon as possible. It’s always better to show you’re correcting things quickly rather than leaving them unresolved. Getting into a habit of tracking your VAT dates early helps avoid this situation altogether.
3. How can I avoid VAT return penalties?
The best way to avoid VAT penalties is to stay organised. Use accounting software that’s compliant with Making Tax Digital, as it reminds you of due dates and lets you file directly to HMRC. Try to check your VAT figures every month, even if you file quarterly, so there are no surprises when the deadline comes.
Filing early gives you breathing space in case something goes wrong—like a payment delay or portal issue. Make sure your invoices and receipts are stored digitally and linked to your VAT records.
If you work with an accountant, send everything on time so they don’t have to rush. Keeping your system up to date and adding alerts for each return date can make VAT filing simple, stress-free, and penalty-free.
4. Can I get a penalty removed if I filed late by mistake?
You might be able to, yes. HMRC sometimes removes or reduces a penalty if you can show you had a “reasonable excuse.” This could include being seriously unwell, encountering unexpected technical issues with the HMRC portal, or dealing with something genuinely beyond your control.
Forgetting the deadline or being too busy usually doesn’t count, though. If you think your reason is valid, contact HMRC as soon as possible and explain what happened. Include any proof if you can, such as screenshots or emails.
The sooner you appeal, the better your chances. Even if HMRC accepts your appeal, they’ll expect you to stay compliant going forward. Setting up reminders and using reliable VAT software helps ensure you don’t end up in the same situation again.
5. What’s the easiest way to stay ahead of VAT return deadlines?
The easiest way to stay on top of your VAT return deadlines is to keep organised and use reliable digital tools. Set reminders on your phone or calendar a week before each due date, so you never forget to file. Keep your invoices and expense records in one place and update them regularly, rather than waiting until the last minute.
Using MTD-compliant software helps too, as it automatically tracks deadlines and updates your VAT data in real time. This means fewer mistakes and less stress when submitting returns. You can also log in anytime to check your filing status or confirm what’s due next.
By planning early, reviewing your figures monthly, and using trusted software, you can submit on time, avoid penalties, and keep your business running smoothly without worrying about HMRC deadlines.
