VAT in Xero: MTD Submissions, Adjustments, and Partial Exemption Walkthrough for UK VAT Returns

VAT in Xero can feel complex when you face MTD rules, corrections, and partial exemption at the same time. You need a clear path that shows what Xero does, what HMRC expects, and where you must check the numbers.

You can submit MTD VAT returns in Xero, make allowed VAT adjustments, and deal with partial exemption inside the VAT return before you file to HMRC. When you know how the system pulls data and where changes are allowed, you stay compliant and avoid last‑minute errors.

This guide walks you through how Xero links to HMRC, how to prepare and submit your return, and how to handle adjustments with confidence. You also learn practical tips that help you use Xero’s VAT tools with more control and fewer surprises.

Understanding MTD for VAT and Xero Integration

Making Tax Digital for VAT changes how you record, submit, and manage VAT. HMRC now expects digital records, digital links, and software-based submissions, and Xero meets these rules for most VAT-registered businesses.

Overview of Making Tax Digital for VAT

Making Tax Digital, often called MTD, is an HMRC programme that moves VAT reporting to fully digital systems. If you run a VAT-registered business, you must keep VAT records in digital form and submit VAT returns through MTD software.

You can no longer type figures into HMRC’s online VAT portal. Instead, your accounting system must send the data directly to HMRC using an approved connection.

MTD for VAT applies to all VAT-registered businesses, including sole traders, partnerships, and limited companies. This rule applies regardless of turnover.

MTD for VAT focuses on three areas:

  • Digital VAT records
  • Digital links between systems
  • Software-based VAT return submissions

HMRC Requirements for VAT-Registered Businesses

HMRC requires you to store specific VAT data digitally. This includes sales and purchase amounts, VAT rates, and transaction dates. You must keep these records for at least six years.

You must also maintain digital links. This means you cannot copy and paste VAT figures between systems. Any transfer of data must happen through a digital connection.

You must submit your VAT return using MTD-compatible software. HMRC will reject returns sent through older online filing methods.

Key compliance points include:

  • Accurate digital record keeping
  • Timely VAT submissions
  • Correct handling of adjustments and penalties

Late submissions or payments can lead to points and financial penalties under HMRC’s penalty system.

Xero’s Role as MTD-Compatible Accounting Software

Xero acts as MTD-compatible accounting software that connects directly to HMRC. You can use it to keep digital VAT records and submit VAT returns without manual re-entry.

You authorise Xero once, then submit VAT returns from within the software. Xero pulls data from your transactions and fills in the VAT return boxes automatically.

Xero also supports VAT adjustments, flat rate schemes, and partial exemption calculations. This helps you stay compliant while reducing errors.

With Xero, you can:

  • Submit MTD for VAT returns
  • Track VAT in real time
  • Review audit trails and reports

You remain responsible for accuracy, but Xero provides the tools to meet HMRC’s MTD rules with confidence.

Preparing and Submitting MTD VAT Returns in Xero

You prepare MTD VAT returns in Xero by setting up the correct tax details, keeping clean digital records, and submitting returns directly to HMRC. Xero acts as your MTD software, so you manage calculations, adjustments, and submissions in one place.

Setting Up MTD for VAT in Xero

You start by confirming that your organisation is VAT registered and enrolled in MTD for VAT with HMRC. In Xero, you enter your VAT registration number, VAT scheme, and filing frequency under tax settings.

You then check user access. Only users with the right role can view or file VAT returns. To submit returns, you need permission to file MTD VAT returns.

You must also review VAT rates and tracking categories. Incorrect setup can lead to errors in your digital records. Before filing, make sure Xero shows the correct VAT periods and that all transactions fall within the right dates.

Filing VAT Returns Through MTD

You prepare your VAT return from the VAT Return report in Xero. The report pulls totals directly from your accounting data, which supports MTD compliance.

Before you submit, review each box carefully. You can add adjustments in Xero where allowed, such as manual corrections or partial exemption adjustments. Xero records these changes in the return.

When ready, you submit the return directly to HMRC through Xero. You cannot use the old HMRC VAT portal for MTD VAT returns.

Key checks before filing:

  • All transactions are reconciled
  • Adjustments are correct and documented
  • The return period matches HMRC deadlines

Maintaining Digital Record Keeping and Digital Audit Trail

You must keep digital record keeping under MTD rules. This means you record sales, purchases, and VAT amounts in your accounting software without manual re-entry.

Xero stores these digital records and links them to your VAT return. This creates a clear digital audit trail from each transaction to the final figures submitted to HMRC.

You should avoid spreadsheets unless they connect digitally to Xero. Any break in the digital link can cause non-compliance. Regular bank feeds and proper coding help keep records accurate and complete.

Connecting to HMRC and Ensuring Compliance

You connect Xero to HMRC using your Government Gateway login. This authorisation allows Xero to submit returns and receive confirmation messages.

Once connected, Xero shows submission status and receipt references from HMRC. You should keep these records for your compliance files.

You also need to monitor ongoing MTD compliance. This includes meeting deadlines, keeping digital records up to date, and using approved MTD software at all times. If your VAT details change, update both HMRC and Xero without delay.

Handling VAT Adjustments and Partial Exemption in Xero

You often need to adjust VAT figures before submission, especially when transactions change or supplies include both taxable and exempt income. Xero gives you tools to edit VAT returns, apply partial exemption rules, and keep your financial reports accurate.

Editing and Adjusting VAT Return Amounts

You can adjust VAT returns in Xero before you submit them under MTD. Xero shows each change in the History panel and updates the Transactions by VAT view.

You usually adjust figures in two ways:

  • Edit individual transactions to correct VAT codes or amounts
  • Add a VAT adjustment directly to the return for rounding errors or corrections

Use VAT adjustments for one-off changes, not routine errors. Xero only allows these adjustments if you use the standard VAT scheme.

For large or complex changes, you may use a manual journal. Do this with care. Manual journals affect VAT returns and financial reports, so you should confirm the figures before saving.

Managing Partial Exemption Calculations

Partial exemption applies when you make both taxable and exempt supplies. You can only reclaim VAT that relates to taxable income.

Xero does not calculate partial exemption for you. You must work out the recoverable VAT outside the system, often in a spreadsheet. You then enter the non-recoverable amount as a VAT adjustment to Box 4.

Common steps include:

  1. Calculate total input VAT
  2. Work out the recoverable percentage
  3. Reduce Box 4 by the non-recoverable amount

Xero records the adjustment and keeps a clear audit trail. This helps support your figures during reviews or HMRC checks.

Common Scenarios for VAT Adjustments

You may need VAT adjustments in several routine situations. These often appear near the end of a VAT period.

Typical scenarios include:

  • Partial exemption restrictions on overheads
  • Late VAT claims for older purchase invoices
  • Errors in VAT codes on expenses or income
  • Rounding differences caused by multiple transactions

You should always review VAT returns before submission. Check Box 4 and Box 7 against your financial reports. Small errors can affect cash flow and compliance, so clear records in your accounting software matter.

Best Practices and Advanced Features for VAT in Xero

You can reduce VAT errors and save time in Xero by using built-in tools that support digital records, clear reporting, and Making Tax Digital rules. These features work best when you apply them as part of your regular bookkeeping routine, not just at filing time.

Receipt Capture for Digital Records

Receipt capture helps you keep full digital records, which MTD requires. You can upload receipts using the Xero mobile app, email them to Xero, or add them directly on your desktop. Xero reads key details such as date, supplier, and total.

You should still review each receipt before you publish it. Check the VAT rate, VAT amount, and supplier name. Set the correct VAT code so the transaction flows into the right VAT return boxes.

Good habits for receipt capture:

  • Upload receipts as soon as you receive them
  • Match receipts to bank transactions where possible
  • Store original images to support HMRC checks

Leveraging Financial Reports for MTD

Xero’s financial reports help you spot VAT issues before submission. The VAT Report shows totals for each VAT box and links back to source transactions. You can drill down to see what makes up each figure.

Use the Detailed Transaction Report to review VAT by date, rate, or account. This helps you find missing VAT, wrong codes, or duplicate entries. Run these reports before you finalise your return.

Key reports to review:

  • VAT Report
  • General Ledger with VAT columns
  • Profit and Loss for sense checks

Staying Up-To-Date with MTD Compliance

MTD compliance relies on digital links from source data to submission. You should avoid manual retyping of VAT figures outside Xero. Make adjustments using Xero’s VAT return tools where allowed, especially on the standard VAT scheme.

Keep your Xero file updated with the correct VAT scheme, filing frequency, and HMRC connection. Reauthorise the HMRC link when prompted to avoid failed submissions.

MTD checks to review regularly:

  • VAT settings and scheme
  • HMRC authorisation status
  • Digital record completeness

These steps help you stay compliant and reduce last-minute problems.
