Key takeaways
- Late VAT returns can trigger VAT penalty points and fixed charges (Determinations) even when the return is nil or a repayment return.
- Late VAT payments can trigger penalties after 15 days, a bigger hit after 30 days, and an ongoing daily penalty element after day 31.
- Late payment interest runs from the first day after the due date until HMRC receive cleared funds, so small delays still cost money.
- HMRC late payment interest (When the taxpayer owes HMRC) is currently 7.75% from 9 January 2026, and the repayment interest rate is 2.75% (when HMRC owes the taxpayer) from the same date.
- A Time to Pay arrangement can reduce or stop late payment penalties if you act quickly and stick to the plan.
- Many VAT penalties are operational failures, not “tax knowledge” failures, so fixing workflows is the fastest long-term win.
- VAT consultancy often costs less than repeated penalties because it prevents repeats, cleans up coding, and keeps you compliant under MTD.
How HMRC VAT penalties and VAT interest work together
VAT penalties and VAT interest are separate charges that can apply at the same time.
Interest is a running charge for paying late until the Vat is fully payed off, while penalties are charges for breaking compliance rules like filing late, paying late beyond certain thresholds, or submitting inaccurate figures known as returns. It is normal to see both on a single VAT period, especially if the return was filed late and payment was late too.
VAT costs can snowball because multiple triggers / reasons can be active at once.
A late submission creates points and potentially a £200 penalty as well as an additional %tge of any tax that is due, a late payment creates late payment penalties and interest, and an incorrect return can create an inaccuracy assessment on top. The fastest way to reduce the total cost is to identify which trigger / reason applies and shut down the next trigger / reason immediately.
What counts as “late” for VAT in real life
A VAT obligation is late when HMRC do not receive a valid VAT return or cleared payment by the relevant due date.
This is where many businesses get caught out, because “I pressed submit” and “I sent a bank transfer” are not always the same as “HMRC accepted the return” and “HMRC received the funds”.
Direct debit VAT payments have a practical cut-off that can be earlier than you expect.
If you use direct debit, you still need to submit the VAT return in time for HMRC to collect it, and a late return can cause the collection to fail even if you thought payment was automated.
Bank transfers are only on time when the money clears.
A payment instruction on the due date is not always a cleared payment on the due date, especially around weekends, bank holidays, and bank processing cut-offs.
Nil VAT returns still attract late submission points if they are late.
A common and expensive misconception is that “no VAT due” means “no penalty risk”, but VAT late submission rules apply even where the return shows nothing payable.
The current VAT late submission penalty regime
Late VAT return penalties arise under a points-based system for VAT periods starting on or after 1 January 2023.
Under this approach, each late VAT return usually triggers a penalty point, and once you reach a points threshold you can be charged fixed penalties.
VAT penalty points are separate from late payment penalties.
You can file on time and still be penalised for paying late, and you can pay on time and still be penalised for filing late, so you need two controls: one for submission and one for payment.
How VAT penalty points build up
Each late VAT return normally adds one point until you reach your threshold.
The threshold depends on how often you submit returns, which matters because monthly filers have more opportunities to be late and annual filers have fewer.
The typical thresholds used in practice are:
- annual returns: 2 points
- quarterly returns: 4 points
- monthly returns: 5 points
Once you hit the threshold, HMRC can issue a fixed £200 penalty.
After that, every further late return while you remain at the threshold can create another £200 penalty, which is why repeated lateness becomes expensive quickly.
Why nil and repayment returns still hurt
Nil and repayment VAT returns can still generate penalty points if submitted late.
This traps businesses who delay filing because they are busy, because they are waiting for a report, or because they fear a VAT liability and avoid the process entirely.
How VAT penalty points expire or reset
Penalty points can expire if you stay below the threshold and keep filing on time long enough.
The expiry window is long enough that casual improvements do not always clear points quickly, so points can sit in the background and create a bigger risk later.
Points reset after reaching the threshold only when you meet the conditions HMRC apply.
In practice, you normally need to submit all outstanding returns and maintain on-time compliance for a set period, which means catching up missing periods is not optional if you want to stop the cycle.

The current VAT late payment penalty regime
Late VAT payment penalties arise when you do not pay VAT by the due date and the VAT remains overdue beyond specific day thresholds.
The rule design is deliberate: HMRC give you a short window to correct a cash flow slip, then the charges step up.
Late payment penalties are driven by day counts, not your intentions.
Even if your reason was genuine, the penalty system still triggers automatically unless you take action in the right window.
Days 1 to 15 overdue
You usually avoid a late payment penalty if you pay in full within the first 15 days after the due date or you agree a payment plan quickly.
This window is a big deal commercially because once you pass it, costs start to become material.
Days 16 to 30 overdue
A first late payment penalty usually applies once the VAT is more than 15 days overdue.
In practical terms, paying on day 16 can cost meaningfully more than paying on day 15, even if the VAT amount and the cash problem are identical.
Day 31 onwards
Late payment penalties generally increase after day 30 and an ongoing daily penalty element can begin from day 31 until the VAT is paid.
This is the danger zone because you can have penalties and interest running at the same time while HMRC’s debt collection approach also becomes more assertive.
Why the rates matter for businesses right now
Late payment penalty rates are higher than they used to be for businesses within the modern digital penalty regime.
This means a “short-term VAT loan” mindset is usually a false economy, because the penalty structure is designed to make waiting expensive.
VAT late payment interest
VAT late payment interest arises when VAT is overdue, and it runs from the first day after the due date until the day HMRC receive cleared payment.
Interest is separate from penalties, and it can apply even when a penalty does not, which is why quick action still matters inside the first 15 days.
HMRC’s late payment interest rate is currently 7.75% from 9 January 2026.
The repayment interest rate is currently 2.75% from 9 January 2026, and this may apply in limited situations where HMRC have delayed a repayment under their rules.
Interest rates can change, so you must treat the percentage as time-sensitive.
The practical point is not the exact percentage, it is that interest runs daily and continues while any balance remains unpaid.
Why interest feels harder to remove than a penalty
Interest is usually charged as a statutory consequence of being late rather than a behavioural punishment.
This means the realistic way to reduce interest is to reduce the number of overdue days, correct allocation errors, or challenge clear calculation issues rather than relying on sympathy arguments.
Time to Pay for VAT
A Time to Pay arrangement can reduce or stop late payment penalties if you request it early and keep to the agreement.
This is one of the biggest commercial levers available, but it only works when you act quickly and propose a plan you can actually sustain.
Time to Pay is not a magic reset button for poor VAT habits.
HMRC generally expect you to stay current with new VAT liabilities while you repay the arrears, and failing to do that often breaks the arrangement and creates more cost.
When you should request Time to Pay
You should request Time to Pay as soon as you know you cannot pay the VAT on time.
The most expensive mistake is waiting until you are already past day 30, because penalties are already stacking and HMRC are less likely to view the situation as controlled.
What HMRC usually care about in a payment plan
HMRC usually want affordability and credibility, not long explanations.
Affordability means your instalments fit your real cash flow, and credibility means you will keep filing VAT returns on time and paying new VAT on time.
VAT inaccuracy penalties
VAT inaccuracy penalties arise when HMRC believe your VAT return includes errors that lead to underpaid VAT or over-claimed input VAT.
Many businesses assume they only face VAT penalties when they are late, but errors can be just as costly, especially when the error is repeated across multiple quarters.
Inaccuracy penalties depend heavily on behaviour and evidence.
A one-off careless mistake with good records is treated differently from repeated errors with weak systems, and the quality of your working papers often influences how HMRC view the situation.
Common VAT errors that trigger penalties
Wrong VAT rates cause big problems because they affect revenue lines, not one-off transactions.
A single miscode on a product category can create a large under-declaration across months, and HMRC often spot patterns quickly in digital records.
Invalid input VAT claims are a common trigger because evidence rules are strict.
If you cannot produce a valid VAT invoice, or the supplier is not VAT registered, or the purchase is blocked, HMRC can disallow the claim and treat the difference as an inaccuracy.
Reverse charge mistakes are common where systems are not configured properly.
This is especially relevant in sectors with reverse charge rules, where output tax and input tax entries must be mirrored correctly.
Import VAT and postponed accounting errors arise when statements are not reconciled.
If you do not match import statements to the VAT return properly, you can miss claims, double claim, or put amounts in the wrong period.
Partial exemption errors arise when you have both taxable and exempt income.
These calculations are evidence-heavy and judgement-based, so poor working papers increase the chance of HMRC challenge.
Late VAT registration penalties
Late VAT registration penalties arise when you should have registered earlier but did not notify HMRC on time.
This can be financially brutal because HMRC can backdate registration, meaning you may owe output VAT on past sales that you can no longer recover from customers.
Late registration often happens because owners track turnover incorrectly.
The VAT threshold test is usually based on rolling 12-month taxable turnover, so a strong trading period can trigger the threshold unexpectedly.
Late VAT registration can create multiple knock-on costs.
You may face VAT due, late payment interest, potential penalties for failure to notify, and significant admin time to clean up historic invoices and records.
VAT assessments and estimates
VAT assessments arise when HMRC estimate what you owe, often due to missing returns or unresolved compliance issues.
An assessment is rarely kind, because HMRC will protect the tax position first and negotiate later.
Assessments can create penalty and interest exposure even if the estimate is wrong.
If you ignore an assessment, interest can run and late payment penalties can apply to the assessed balance, so doing nothing is normally the most expensive choice.
Making Tax Digital for VAT and why it increases penalty risk
MTD for VAT increases penalty risk when your recordkeeping and submission process are not genuinely reliable and digitally connected.
Most VAT penalties today are caused by workflow issues: missing bank reconciliations, broken software syncing, late approvals, and last-minute scrambling.
Manual workarounds increase error risk.
Copying totals into spreadsheets, rekeying in numbers, and relying on one person’s knowledge creates a fragile system that breaks when that one person with all the knowledge may be away.
A boring yet VAT process is the safest VAT process.
Businesses that treat VAT like a routine production line tend to avoid both late penalties and inaccuracy penalties, because the process catches problems early.
The commercial reality of VAT penalties
VAT penalties hit profit directly, and they also create hidden cost in management time and stress.
A £200 late submission penalty is annoying, but the bigger cost is often the disruption: dealing with HMRC letters, fixing records under pressure, and carrying arrears that damage cash flow.
VAT penalty patterns can trigger compliance attention.
Repeated late filing, frequent Time to Pay requests, and inconsistent VAT figures can increase the chance of HMRC queries, especially where repayment claims are involved.
What to do if you receive a VAT penalty notice or an interest charge
You reduce VAT penalties by acting quickly, checking the facts, and fixing the cause, not just the symptom.
Most businesses make things worse by panicking, sending half-formed explanations, or ignoring the notice until it becomes enforcement.
Step 1: Identify the type of charge
You should confirm whether the charge relates to late submission, late payment, inaccuracy, or late registration.
Each has different rules, different timelines, and different evidence requirements, so treating everything as “a VAT penalty” wastes time.
Step 2: Check dates and allocations
You should check the return due date, submission date, payment due date, and the date HMRC treated the payment as received.
A meaningful number of disputes come down to misallocated payments, wrong references, or bank timing, and those can be corrected with evidence.
Step 3: Decide if you have a reasonable excuse for a penalty
You should only use a reasonable excuse approach when you have evidence and a clear timeline.
A reasonable excuse is not “cash was tight”, it is usually something that genuinely prevented compliance and was resolved promptly once the obstacle passed.
Step 4: Stop the next penalty before it happens
You should create a simple action plan for the next VAT period immediately.
If you leave the process unchanged, you often get hit again next quarter, and repeat problems are where penalties become predictable and expensive.
Simple controls that prevent most VAT penalties
Most VAT penalties can be prevented by five boring controls applied consistently.
These controls are especially powerful for owner-managed businesses where directors have limited time and need repeatable systems.
Control 1: Internal VAT cut-off dates
You should set a VAT preparation cut-off date at least 10 to 14 days before the HMRC deadline.
This gives time for reconciliations, missing invoices, and review, which prevents last-minute errors and late submissions.
Control 2: Clear responsibility for VAT preparation and approval
You should assign one person to prepare, one person to review, and one person to approve submission.
This prevents the common failure where everyone assumes someone else is on it.
Control 3: Monthly reconciliations
You should reconcile bank, sales control, purchase control, and the VAT control account monthly.
Quarter-end VAT work becomes easier and faster when most issues are already dealt with month by month.
Control 4: Ringfence VAT money
You should treat VAT collected as not your money and move it into a separate pot.
This is the simplest cash flow control for avoiding late payment penalties and Time to Pay reliance.
Control 5: A high-risk VAT checklist
You should use a checklist for reverse charge items, imports, entertainment, mixed-use costs, and unusual supplies.
This reduces inaccuracy risk and improves audit readiness if HMRC ever query the return.
How to contact the HMRC Vat department to obtain information and discuss your penalties
You may become aware of a fine or penalty or late payment interest via a letter or online notice on your business govt gateway portal. If you have received a letter from HMRC or believe you may have penalties and or interest to pay to HMRC. Then you can contact HMRC in three different ways to request information to try and resolve this.
1) Via Letter: BT VAT, HM Revenue and Customs, BX9 1WR. United Kingdom. Ensure you include your business name, address, business owner’s name, and VAT number in the correspondence.
2) Via Phone: Who called the HMRC VAT helpline on 0300 200 3700 They are open on Mondays to Fridays from 8:00 AM to 6:00 PM. It is best to choose the last option when ringing them, which takes you through to an advisor. If the VAT advisor that you speak to cant answer your query then ask to speak to a Technical Advisor who is more senior and has more knowledge.
3) Ask HMRC Digital Vat Assistant online. At times, this option is limited because online call handlers are constrained by the amount of work they can handle and the information they can provide.
How to appeal historic penalties and fines from the VAT department.
When you have received historic HMRC penalties and fines for late filing and late payment of your VAT, you may be able to appeal these via a letter.
There are many common reasons for receiving penalties that may not be the taxpayer’s fault, such as;
Change in VAT scheme, leading to changes in filing dates and deadlines.
The accountant who is filing on your behalf had a problem on his side and was unable to file on time
The taxpayer may have moved address and not received important information regarding filing dates and deadlines. So was unaware of the filing dates due
Registration can take up to nine months when HMRC are busy, and the first important letter of registration informing filing dates may have gone missing in the post.
A client may have moved their payments from direct debit to manual payments or vice versa. Also, a client may have a direct debit set up, but paid part payments to HMRC within the first quarter. Multiple part payments from the taxpayer also confuse the system.
The software which filed the VAT return via the MTD online filing system may have had an error during filing, so HMRC did not receive the return
HMRC’s capture software did not correctly receive the return from mtd filing software, such as Xero, when it was sent to them.
The taxpayer may be going through family or personal circumstances, or be ill, that have led them to miss the filing or payment deadlines.
These are valid reasons for missing deadlines and receiving fines. To appeal, write a polite letter explaining your situation chronologically, outlining the causes of the penalties, and requesting cancellation, as these were isolated incidents. Consult your VAT specialist to draft the letter, and include supporting documents. Total Books specialises in assisting clients with VAT fine cancellations by submitting mitigating letters to HMRC.

FAQ
Do I get VAT penalty points if my VAT return is nil or shows a repayment?
Yes, a nil VAT return or a repayment VAT return can still trigger late submission penalty points if you file after the deadline.
The penalty points system focuses on whether you submitted on time, not whether VAT was payable. This catches businesses that delay filing because they are busy or because they believe there is no cash consequence. The safest habit is to file every VAT return on time, even when the numbers are small, because points can accumulate quietly and later trigger fixed penalties.
When do late payment penalties start for VAT?
Late payment penalties start once your VAT is more than 15 days overdue, and they usually increase again once the VAT is more than 30 days overdue.
The first 15 days are effectively your chance to pay quickly or agree a Time to Pay arrangement before penalty charges begin. After that, the costs rise and can include additional charges from day 31 onwards. From a commercial perspective, the earlier you act, the more you can limit the total cost, even if you cannot pay in full immediately.
Does VAT interest start immediately after the due date?
Yes, late payment interest normally starts from the first day after your VAT payment due date and runs until HMRC receive cleared payment in full.
This means a short delay can still create a charge, and interest can keep building while you are negotiating or paying by instalments. Interest is separate from penalties, so even if you avoid a late payment penalty in the early window, you can still face interest for the days the VAT was overdue. Speed matters because it reduces the number of interest days.
Can a Time to Pay arrangement stop VAT late payment penalties?
Yes, a Time to Pay arrangement can reduce or stop late payment penalties if it is agreed quickly and you keep to the plan.
The key is requesting it early and proposing instalments that you can realistically maintain. HMRC generally expect you to stay up to date with new VAT returns and new VAT payments during the arrangement, and if you fail to do that the plan can break and costs can increase. A strong Time to Pay request is usually supported by a simple cash flow view and clear evidence of current compliance.
Why do businesses get VAT penalties even when they use accounting software?
Businesses get VAT penalties because software does not fix broken processes, missing records, or late approvals.
MTD-compatible software helps with submission, but it cannot force your team to reconcile bank feeds, chase invoices, code correctly, and approve the return on time. Penalties often arise when bookkeeping is left to the last minute, systems do not sync properly, or the director is too busy to sign off. The fix is operational: internal cut-offs, monthly reconciliations, clear ownership, and ringfencing VAT cash.
What is the fastest way to stop repeat VAT penalties?
The fastest way to stop repeat VAT penalties is to tighten your VAT workflow with earlier internal deadlines, monthly reconciliations, and ringfenced VAT funds.
Once those basics are in place, you reduce late filings, reduce payment slippage, and reduce the risk of incorrect returns that trigger inaccuracy challenges. If you already have points or repeated late payments, you also need a recovery plan to get back into a clean compliance rhythm. VAT consultancy is most valuable when it turns VAT into a predictable routine rather than a quarterly emergency.
