Many people mistakenly believe they don’t have to submit VAT returns if there was no trading activity. this guide explains what HMRC requires and how to file VAT online.
Understanding how HMRC views seasonal & dormant businesses VAT
HMRC sets the same deadlines for all businesses, including seasonal or dormant ones. If your VAT registration is active, you must file returns on time. HMRC expects precise figures for each period, even if all are zero.
This shows your business is still operating, even at a low level, and hasn’t stopped trading without notifying HMRC.
Examples of seasonal businesses are holiday rentals, tourism services, event stalls, garden services, and ice cream vans. Dormant companies are those that temporarily stop trading but plan to resume operations.
If you want to pause VAT obligations completely, you need to ask for deregistration. Otherwise, HMRC expects a return for every period.
If you don’t submit VAT online for seasonal or dormant businesses, it can hurt your compliance record. It may also prevent you from claiming VAT refunds when your business resumes operations.
What HMRC expects when you submit VAT online during non-trading periods
For each period, HMRC requires precise data. Enter zeros in every box to file a nil return if you had no sales or purchases.
As long as the returns show actual non-trading activity, HMRC accepts zero returns. Even if there were no transactions, your data should match your records.
You should keep invoices, receipts, or other records even when your business is dormant. Keep these records for six years. This helps if HMRC audits you, as they sometimes verify that a nil return is correct.
HMRC checks that you meet VAT deadlines. If you miss the filing date, HMRC can add extra charges and apply interest on the amount you owe.

How to submit VAT online for seasonal or dormant businesses
Submitting VAT online works the same as during regular trading. The only difference is that you enter zeros if there’s no business activity.
- Log in to your VAT account with your government gateway credentials.
- Select the period for which you want to file.
- Enter zero in all boxes if there were no sales, purchases, or VAT movements.
- Check your summary carefully to ensure no boxes contain old data by mistake.
- Submit the return and wait for confirmation. Seasonal or dormant businesses should use MTD-compatible software to file returns. This makes the process easier and helps prevent mistakes.
Common mistakes when submitting VAT online for non-trading periods
Some businesses submit VAT returns online with incorrect or missing information, which causes compliance issues. Here are the most common mistakes HMRC sees.
Submitting late:
Seasonal and dormant companies sometimes miss the deadline for trading, but HMRC still expects you to file on time. Make sure to enter zero values instead of leaving fields blank. Leaving a field blank can cause errors when you submit.
Reporting made up estimates:
Some firms enter small figures even when nothing happened in the period. HMRC often notices this and may review the return if the numbers don’t match genuine non-trading activity.
Mismatched records:
Even when your business is dormant, you need to keep records. If HMRC requests documents and you can’t provide them, it may appear you guessed the figures. This is a serious issue. Even if your business is closed for months, you must still file the return.
Ignorance of MTD rules:
Every business registered for VAT has to comply with the MTD rules. This includes seasonal or dormant companies that also require the software.
Why accurate VAT submissions matter during low or no activity periods
Filing VAT returns correctly keeps your business in good standing. HMRC tracks how you file. Clean and timely returns help you avoid compliance checks. A good record is essential when you start trading again and want to claim refunds or file VAT returns.
It also helps your business maintain its credit standing, as lenders sometimes review financial compliance. Missing VAT returns can often affect trust.
Good compliance is essential for seasonal businesses to avoid issues during peak months. You risk losing money during your busy season if HMRC places a trading restriction on you for missing returns.
Avoid errors when you submit VAT online for seasonal or dormant businesses
Each period, follow the same procedure. Even when you’re not trading, remember deadlines. To avoid empty fields or incorrect formats, use MTD-compatible software.
Maintain simple records showing no purchases or sales, and include a brief note at the end of each period to confirm that nothing has occurred. This protects you from errors and helps in audits.
To ensure that you never forget a return, set calendar reminders. Seasonal businesses often overlook reminders during quiet periods, only to remember them during busy periods. Consider VAT returns as an essential aspect of maintaining compliance.
HMRC checks and how to stay compliant
HMRC sometimes runs automatic digital checks. If you file several nil returns in a row, they may ask if your business is still active or if you want to deregister. Make sure you reply on time. If you’re still trading seasonally, keep filing nil returns.
If you plan to stop trading for good, deregister to avoid future obligations. Once you deregister, you no longer need to file returns.
When should a seasonal or dormant business deregister
Final Thoughts
HMRC still requires accurate online returns every period, even though several seasonal and dormant businesses put VAT low on their list during slow periods. When there is no activity, a zero return is acceptable as long as it is submitted on time and supported by fundamental documentation.
Frequently Asked Questions:
Your Questions – Answered ,We’re here to help you with anything VAT-related.
1. Do I need to submit a VAT return if my business didn’t trade at all?
Yes, even if your business had absolutely no activity during the VAT period, you still need to submit a return. HMRC treats seasonal and dormant businesses the same as fully active ones as long as the VAT registration is still open.
That means you must log in and file a nil return, which simply means entering zero in every box. Many business owners think “no sales = no return,” but HMRC still expects a submission to confirm that nothing happened. Filing a nil return also protects you from penalties and unnecessary compliance checks.
Missing a return can trigger reminders, interest, or even automated reviews. So even though it feels like an extra step during quiet periods, filing on time keeps your account clean and ensures everything runs smoothly when you start trading again.
2. What records do I need to keep if my business is dormant?
Even if your business isn’t trading, record-keeping is still essential. HMRC expects you to keep basic documentation for at least six years, even during dormant periods. This includes invoices, receipts, expense records, and any documentation that shows whether activity occurred during the VAT period.
If nothing happened, a simple note or summary confirming “no sales or purchases this period” is enough to support your nil return. This matters because HMRC sometimes checks whether zero returns are genuine.
If they request supporting documents and you can’t provide them, it may appear that you estimated or guessed the figures. Keeping clear, simple records protects your business and shows that the nil return was accurate. It also makes things much easier when you start trading again and need to pick up where you left off.
3. What happens if I forget to file my VAT return during a no-trade period?
If you miss a VAT deadline, even during a period with no business activity, HMRC can apply penalties and interest. Many business owners assume a non-trading period isn’t as important, but HMRC treats every VAT period equally.
Missing a return can affect your compliance record, which may trigger reminders or digital checks. In some cases, HMRC might even ask whether your business is still active or should be deregistered. The good news is that if you realise the mistake early, you can still file the return promptly to minimise issues.
Setting reminders or using MTD-compatible software is one of the easiest ways to avoid this problem. Filing on time keeps your VAT account clean and makes future submissions, especially once trading resumes, much smoother.
4. Can I deregister for VAT if my business is seasonal or temporarily closed?
You can deregister only if your business has permanently stopped trading or your turnover is expected to remain below the VAT threshold long-term. If your business pauses only during certain months— such as holiday rentals, garden services, or event stalls—HMRC still considers you active.
In that case, it’s better to remain registered so you can reclaim VAT and avoid having to reapply later. If you’re dormant for a short period but plan to reopen, keeping your registration active is usually the smoother option.
Deregistering too early can create complications, such as the need to file a final VAT return or repay input VAT on stock or assets. Consider deregistration only if you’re sure the business won’t resume operations soon. Otherwise, filing regular nil returns is the safest and simplest way to stay compliant.
5. How do I submit a nil VAT return using MTD software?
Submitting a nil VAT return through MTD software is almost identical to submitting a regular return — the only difference is that every field contains a zero. Start by logging in to your MTD-compatible software, selecting the VAT period you’re filing for, and entering 0 in all required fields. Before submitting, double-check that no old numbers have carried over from previous returns, as this is a common mistake.
Some software automatically highlights missing fields or unusual entries, making it easier to avoid errors. Once everything looks correct, submit the return and wait for HMRC confirmation.
This confirmation is essential because it shows that your return was received and accepted. Using software not only simplifies nil returns but also keeps everything organised for future filings, which is especially helpful for businesses with seasonal or irregular activity.
