VAT Submission Services UK – VAT Return Preparation, Filing & HMRC Compliance

Audit Consulting Group provides professional VAT submission services for UK businesses that need their VAT returns prepared, reviewed and submitted accurately through Making Tax Digital. We support limited companies, SMEs, sole traders, contractors, e-commerce businesses and startups with routine VAT returns, overdue filings, reconciliation work and previous VAT errors.

Our work goes beyond entering figures into VAT software. Where required, we review the accounting records behind the return, reconcile transactions, calculate input and output VAT, identify inconsistencies and confirm the VAT position before submission to HMRC.

What Our VAT Submission Service Includes

The amount of work required depends on your bookkeeping, VAT scheme and transaction complexity. For a business with complete and reconciled records, preparation can be relatively straightforward. Where records are incomplete or unusual transactions are involved, additional review may be needed before the return can be filed responsibly.

• Review of sales, purchases and VAT records for the reporting period
• Reconciliation of relevant bookkeeping balances
• Calculation and review of input VAT and output VAT
• Checks on VAT codes and transaction treatment
• Preparation of the VAT return
• Review of adjustments where applicable
• MTD VAT submission using compatible software
• Confirmation that the return has been submitted
• Support with relevant HMRC queries or filing issues within the agreed scope

What We Check Before Submitting Your VAT Return

A VAT return is only as reliable as the records behind it. Incorrect VAT codes, missing invoices, duplicated transactions or unreconciled balances can all affect the figures ultimately reported to HMRC.

Depending on the business, our review may cover sales invoices, purchase invoices, expense records, credit notes, refunds, import VAT, postponed VAT accounting, reverse charge transactions, previous-period adjustments and the VAT control account.

If the bookkeeping is not up to date, we first establish what needs to be corrected or reconciled. Additional bookkeeping work can be scoped separately where necessary.

VAT Return Preparation, Reconciliation and Submission

These stages are connected, but they are not the same service activity.

VAT return preparation involves calculating the figures that should appear on the return from the relevant accounting records.

VAT reconciliation checks whether those figures agree with the underlying bookkeeping and helps identify discrepancies before filing.

VAT submission is the digital filing of the completed return with HMRC using Making Tax Digital compatible software.

VAT payment is separate from filing. Where VAT is due, the business must ensure payment reaches HMRC by the applicable deadline.

Who Our VAT Submission Service Is For

We support VAT-registered businesses that want professional assistance with preparation, checking or filing, including limited companies, SMEs, sole traders, contractors, startups, e-commerce businesses and businesses with overdue or previously incorrect VAT returns.

You may already have accounting software and bookkeeping in place but want an accountant to review the VAT position before the return is submitted. Alternatively, you may need support bringing the underlying records into order first.

Common VAT Submission Problems We Help With

Many VAT issues begin before the filing stage. Problems often arise because bookkeeping has not been reconciled, supporting documents are missing, VAT codes have been applied incorrectly or previous periods contain unresolved errors.

We can assist with situations such as a first VAT return, incomplete bookkeeping close to a deadline, late VAT submission, incorrect VAT calculations, import VAT issues, reverse charge transactions, previous return errors and HMRC filing problems.

Where figures cannot be properly supported, the priority is to establish what information is missing rather than submitting an unreliable return simply to meet a deadline.

VAT Submission Deadlines UK

For businesses using standard VAT accounting periods, a VAT return is normally due one calendar month and seven days after the end of the VAT period. Payment is generally due by the same deadline.

For example, if a VAT period ends on 31 March, the normal filing and payment deadline would be 7 May.

Different arrangements can apply depending on the VAT scheme or circumstances, so businesses should confirm the deadline for the specific reporting period.

Late VAT Submission and HMRC Penalties

If a VAT return is already overdue, bringing the outstanding filing up to date should normally be treated as a priority.

Late submission and late payment are dealt with separately. Missing VAT return deadlines can result in penalty points and, once the relevant threshold is reached, financial penalties. Late payment can create separate penalties and interest.

Our late VAT submission support may include reviewing outstanding periods, reconciling available records, preparing overdue returns, checking the VAT liability and reviewing relevant HMRC correspondence.

Where there may be grounds for a reasonable-excuse appeal, we can review the circumstances and assist with the response within the agreed scope. The outcome cannot be guaranteed because HMRC considers the facts and evidence of each case.

Already Missed Your VAT Deadline?

If your return is overdue, tell us which VAT period is outstanding, whether the bookkeeping is complete and whether HMRC has already contacted you. We can then establish what needs to be done before filing.

Incorrect VAT Returns and Previous Submission Errors

If you discover an error after a VAT return has been submitted, the correct way to deal with it depends on the nature and size of the error and the applicable HMRC rules.

We can review the transactions concerned, identify how the previous VAT submission was affected and establish what correction process may be required. This can include situations where input VAT was claimed incorrectly, output VAT was omitted, the wrong VAT treatment was applied or bookkeeping errors flowed into the return.

Not every error is corrected in the same way, so the underlying transaction should be reviewed before any amendment or disclosure is made.

Making Tax Digital and Online VAT Submission UK

Businesses within Making Tax Digital for VAT requirements generally need to maintain the required digital records and submit VAT returns using MTD-compatible software, unless an exemption or other permitted arrangement applies.

We can work with established accounting systems such as Xero, QuickBooks and Sage, as well as suitable bridging arrangements where appropriate.

Accounting software can automate calculations and submission, but it cannot determine whether every transaction has been treated correctly for VAT. Reviewing the records remains important even when the accounting system produces the return automatically.

What Information Do We Need?

The exact information depends on your business, but commonly required records include:

• Sales invoices and sales records
• Purchase invoices
• Expense receipts and supporting VAT evidence
• Bank and payment account records
• Access to accounting software where applicable
• Import VAT or postponed VAT accounting records where relevant
• Credit notes and refunds
• Previous VAT returns
• Details of unusual or one-off transactions
• Relevant HMRC correspondence

VAT Returns With More Complex Transactions

Some company VAT submissions need additional review. This may apply where the business deals with imports, postponed VAT accounting, reverse charge transactions, partial exemption, cross-border transactions, capital expenditure or specialist VAT schemes.

Where a matter requires tax analysis beyond routine VAT return preparation, we distinguish that work from the standard submission service and confirm the additional scope before proceeding.

How Our VAT Submission Process Works

1. Review the VAT Period

We confirm the reporting period, deadline, VAT scheme, bookkeeping status and any known problems. Previous returns or HMRC correspondence can be reviewed where relevant.

2. Check and Reconcile the Records

We review the accounting data needed for the return and identify missing records, reconciliation differences or transactions requiring clarification.

3. Prepare the VAT Return

Input VAT, output VAT and relevant adjustments are calculated and the return figures are prepared from the available records.

4. Review the Figures With You

Where client confirmation or additional information is required, we request it before filing. The VAT position should be clear before the return is submitted.

5. Submit the VAT Return to HMRC

Once the return has been prepared, reviewed and approved, it is submitted through the appropriate MTD-compatible software.

6. Confirm Submission

We confirm that the VAT return has been filed and explain any immediate next steps, including the VAT liability shown by the return where applicable.

How Long Does VAT Submission Take?

The filing itself is normally a short part of the process. Most of the time is spent checking whether the figures are correct and supported by the accounting records.

A straightforward return with complete bookkeeping can therefore be prepared considerably faster than one involving missing documents, large transaction volumes, imports, reconciliation issues or previous errors.

If you have an approaching deadline, tell us the filing date when making your enquiry so we can assess the available time and the condition of your records.

VAT Submission Cost UK

VAT submission services typically range from £150 to £300 per return, depending on the complexity of the work required.

The fee can be affected by transaction volume, bookkeeping quality, the VAT scheme used, reconciliation work, imports or reverse charge transactions, previous VAT errors and the urgency of the filing.

Where additional bookkeeping, correction work or specialist VAT advice is required, we identify this separately so the scope and cost are clear before the work proceeds.

What Businesses Often Underestimate About VAT Filing

VAT submission is sometimes treated as an administrative task carried out at the end of each quarter. In practice, the accuracy of the return is heavily influenced by what happened in the bookkeeping during the period.

An incorrect VAT code can flow directly into the return. An unreconciled account can leave transactions duplicated or missing. A purchase may appear in the bookkeeping but still lack the evidence required to support the VAT treatment applied.

Regular bookkeeping and reconciliation usually make VAT return preparation more efficient and give the business more time to investigate unusual transactions before the filing deadline.

Practical VAT Submission Scenarios

First VAT Return After Registration

A newly VAT-registered business may have its accounting software in place but be unsure whether VAT codes and opening transactions have been recorded correctly. A first-return review would typically involve checking the VAT setup, reconciling the reporting period, resolving missing information and preparing the MTD submission.

The objective is a properly supported first return and a clearer process for future VAT periods.

Overdue VAT Return With Incomplete Records

When a VAT return is late and the bookkeeping is also incomplete, submitting immediately may not solve the underlying problem. The records first need to be brought into a usable position, after which the return can be prepared and filed.

If HMRC has already issued correspondence or penalties, these can be considered alongside the filing position rather than treated as an unrelated issue.

VAT Return Involving Imports or Previous Errors

Where a business has import transactions and also identifies an error from an earlier period, both issues need to be reviewed separately. Import VAT records may affect the current return, while the previous error may require a different correction process.

The aim is to establish a clear and supportable VAT position rather than carrying unresolved errors into future returns.

VAT Submission Checklist

Before filing, a business should be comfortable that the relevant sales and purchase records are complete, VAT treatment has been reviewed, supporting evidence is available and the figures have been reconciled where required.

• Check the VAT accounting period and filing deadline
• Reconcile sales and purchase records
• Review VAT codes and rates
• Check input VAT claims
• Consider imports, reverse charge and adjustments where relevant
• Review credit notes and refunds
• Confirm the final VAT figures before digital submission

What Happens After the VAT Return Is Submitted?

Filing the return does not necessarily complete every VAT obligation for the period.

If VAT is payable, the business must ensure the amount reaches HMRC by the applicable deadline. Where the return shows a repayment, HMRC may process the refund or request additional information before releasing it.

Supporting accounting and VAT records should also be retained in accordance with applicable record-keeping requirements. If an error is discovered after filing, it should be reviewed rather than automatically carried into the next period.

For businesses using an ongoing VAT service, the next reporting period can then be managed as part of a regular bookkeeping and compliance cycle rather than reconstructed shortly before each deadline.

Why Businesses Choose Audit Consulting Group for VAT Submission

Our approach focuses on the quality of the VAT records as well as the act of filing the return. This is particularly important when bookkeeping is incomplete, VAT treatment is unclear or previous periods contain issues that need attention.

• VAT preparation, reconciliation and digital submission
• Support for routine, first and overdue VAT returns
• MTD-compatible VAT filing
• Review of previous VAT submission errors where required
• Clear explanation of the information we need from you
• Client review and confirmation before filing where required

Beyond VAT Return Submission

VAT filing can be connected with wider accounting and tax work. Audit Consulting Group can also assist with VAT registration, VAT deregistration, VAT refunds and reclaims, bookkeeping and more complex VAT matters where additional advice is required.

We keep routine VAT submission separate from specialist advisory work so that you understand what is included in the service and what may require additional review.

Frequently Asked Questions About VAT Submission

What is VAT submission in the UK?

VAT submission is the process of filing a VAT return with HMRC for a specific VAT accounting period. The return reports VAT due and VAT that may be reclaimed based on the business’s relevant transactions.

Can an accountant submit my VAT return for me?

Yes. An accountant or authorised agent can prepare and submit VAT returns on behalf of a business where the appropriate HMRC authority and filing arrangements are in place.

How often do businesses submit VAT returns?

Many businesses submit quarterly VAT returns, although monthly reporting or the Annual Accounting Scheme may apply in some circumstances. The reporting periods shown by HMRC should be checked for the individual business.

What is the VAT submission deadline in the UK?

For standard VAT accounting periods, the deadline is normally one calendar month and seven days after the end of the VAT period. Payment is generally due at the same time.

What happens if a VAT return is submitted late?

Late filing can result in penalty points and, once the relevant threshold is reached, a financial penalty. Separate penalties and interest can apply where VAT is paid late.

Can you submit an overdue VAT return?

Yes. We can review the outstanding period, identify any missing records, prepare the return and submit it using the appropriate MTD process. Additional bookkeeping may be required first if the records are incomplete.

Can you correct an incorrect VAT submission?

We can review previous VAT return errors and help establish the appropriate correction process. The correct approach depends on the nature and value of the error and the relevant HMRC requirements.

Can I amend a VAT return after submission?

VAT errors can be corrected, but not every error is dealt with in the same way. Some may be adjusted through VAT accounting, while others may need to be notified separately to HMRC. The transactions should be reviewed before deciding how the correction should be made.

Do I need MTD software for VAT submission?

Businesses within Making Tax Digital for VAT requirements generally need to maintain the required digital records and submit their returns through MTD-compatible software unless an exemption or other permitted arrangement applies.

Can you prepare my VAT return if my bookkeeping is not up to date?

Yes, depending on the condition of the records. We first assess what is missing or unreconciled. Additional bookkeeping or reconciliation may then need to be completed before the VAT return can be prepared accurately.

Can you handle VAT returns involving imports or reverse charge transactions?

Yes. These transactions can be reviewed as part of the VAT return where they fall within the agreed scope. More complex VAT treatment may require additional advisory work.

How long does VAT submission take?

Once the figures are finalised, digital submission is normally quick. The overall turnaround depends on the quality of the bookkeeping, transaction volume, missing records, VAT complexity and how close the business is to its deadline.

How much does a VAT submission service cost?

VAT submission services typically range from £150 to £300 per return depending on complexity. Additional bookkeeping, correction work or specialist VAT advice may be charged separately where required.
