- Xero is a strong all-round VAT filing software choice for many UK small businesses that want a scalable accounting platform.
- SleekBooks is the best fit for Sleek basic-plan customers who want VAT workflows, bookkeeping tasks and accountant collaboration in one connected place.
- The right VAT software depends on whether you need full accounting software, VAT-only filing, bridging software or direct accountant support.
The best VAT filing software UK businesses choose depends on their VAT scheme, bookkeeping setup, budget and how much human support they want. Xero is a strong all-round option for many small businesses, while SleekBooks is a good fit for Sleek customers who want software and accountant collaboration in one connected workflow.
This matters because HMRC’s Making Tax Digital evaluation found that fully functional MTD software saved businesses an estimated 26 to 40 hours per year, with 45% saying it saved them time. Many businesses also pair software with expert VAT return support when they want accountant review before filing.
What are the benefits of VAT filing software?
VAT filing software helps you prepare, check and submit VAT returns with less manual work. The biggest benefit is cleaner bookkeeping before your deadline, not just faster submission.
HMRC estimated that businesses above the VAT threshold using approved VAT-filing software saved an average of 39 hours per year, worth around £730.
Common benefits include:
- Faster VAT return preparation
- Fewer spreadsheet checks
- Cleaner digital records
- Bank feed reconciliation
- Better visibility over VAT owed
- Clearer audit trails
- Easier accountant access
- Fewer missing invoices or receipts
- Less back-and-forth before filing deadlines
VAT filing software is most useful when your business has regular invoices, recurring expenses, imports, exports, multiple VAT rates or an accountant reviewing your return.
Who typically needs VAT filing software?
You typically need VAT filing software if your business is VAT-registered and needs to submit VAT returns to HMRC. This includes limited companies, sole traders, partnerships, ecommerce sellers, contractors, agencies and small businesses that register voluntarily.
You must register for VAT if your taxable turnover goes over £90,000 in a rolling 12-month period. Once VAT-registered, businesses must use compatible software to keep VAT records and file VAT returns, or use bridging software to connect spreadsheets to HMRC.
You may need VAT filing software if:
- You run a VAT-registered limited company
- You are a sole trader above the VAT threshold
- You sell goods or services online
- You import or export goods
- You charge different VAT rates
- You reclaim VAT on business costs
- You work with an accountant or bookkeeper
- You want clearer records before each VAT deadline
If your turnover is close to the limit, Sleek’s VAT threshold guide explains when registration becomes mandatory.
What should you look for in VAT filing software?

Best VAT filing software UK: 7 options to compare
The best VAT filing software UK businesses choose depends on whether they want full accounting software, accountant-led support or a simpler VAT-only tool.
Rank | Software | Best for |
1 | Xero | Best all-round VAT filing software |
2 | SleekBooks | Best for Sleek customers who want accountant collaboration |
3 | FreeAgent | Best for freelancers and simple service businesses |
4 | QuickBooks | Best for businesses already using QuickBooks |
5 | Sage | Best for established businesses wanting structured accounting tools |
6 | Zoho Books | Best for businesses using the wider Zoho ecosystem |
7 | Swift VAT Pro | Best for VAT-only filing |
1. Xero
Xero is the best all-round VAT filing software for many UK small businesses. It works well if you want VAT filing, bookkeeping, bank feeds, reporting and accountant access in one accounting platform.
Xero says all its plans are Making Tax Digital-ready, and that VAT-registered businesses can use Xero to keep digital records and submit compliant returns directly to HMRC.
Xero strengths
- Strong all-round accounting features
- Good bank feed and reconciliation tools
- Familiar to many UK accountants
- Useful reporting for growing businesses
- Large app ecosystem
- Suitable for limited companies, agencies and ecommerce businesses
Xero may suit you if:
- You want one platform for bookkeeping and VAT
- You already work with a Xero accountant
- You expect your business to grow
- You need integrations with other finance tools
The main drawback is that Xero can be more than you need if you only want to submit a simple VAT return. It also works best when it is set up properly from the start.
Sleek’s Xero accounting guide explains how small businesses can use Xero for bookkeeping, invoicing and accounting workflows.
2. SleekBooks
SleekBooks is a strong choice for Sleek customers who want VAT filing software connected to accountant support. It is built around Sleek’s accounting service, rather than being a standalone tool customers manage alone.
SleekBooks supports key finance tasks including invoices, bank feeds, document sharing, transaction notes and accountant collaboration. It is designed to reduce manual bookkeeping admin and keep customers and accountants working from the same information.
SleekBooks strengths
- Built around Sleek’s accounting service
- Keeps finance tasks in one connected workflow
- Supports invoice management and bank feeds
- Lets customers share documents with their accountant
- Helps add context to transactions
- Uses AI-assisted workflows with accountant review
- Localised for UK accounting workflows
SleekBooks may suit you if:
- You already use Sleek for accounting
- You want software and accountant review together
- You dislike switching between tools, emails and folders
- You want clearer collaboration before VAT deadlines
SleekBooks should not be treated as a like-for-like Xero replacement for every business. Xero is a broad accounting platform with a large app ecosystem, while SleekBooks is designed around Sleek’s customer and accountant workflows.
3. FreeAgent
FreeAgent is a good VAT filing software option for freelancers, contractors and small service businesses. It is especially useful if you want a simpler accounting system without too much complexity.
FreeAgent says it can generate MTD-compatible VAT returns from bookkeeping data, submit them directly to HMRC and show how much VAT is owed. It also supports invoice and cash basis returns, the Flat Rate Scheme and other VAT workflows.
FreeAgent strengths
- Simple interface for small businesses
- Useful for freelancers and contractors
- Direct VAT filing to HMRC
- Supports common VAT schemes
- Good fit for service-based businesses
- Easier to use than some larger platforms
FreeAgent may suit you if:
- You run a small service business
- You want simple bookkeeping and VAT returns
- You do not need complex reporting
- You prefer a tool designed around smaller businesses
The main limitation is scale. If your business has more complex reporting, stock, multiple entities or advanced finance processes, Xero or Sage may be a better long-term fit.
4. QuickBooks
QuickBooks is a good option if your business already uses it for invoices, expenses and bookkeeping. It can work well for small businesses that want VAT filing inside a broader accounting system.
QuickBooks says its VAT software calculates VAT owed, sends due-date reminders, checks for common mistakes and lets users submit VAT returns online to HMRC. It also says the software supports standard, cash and flat-rate schemes.
QuickBooks strengths
- Good for businesses already using QuickBooks
- VAT calculations and reminders
- Error-checking features
- Online submission to HMRC
- Useful invoice and expense tools
- Broad small business accounting features
QuickBooks may suit you if:
- You already use QuickBooks
- You want VAT, expenses and invoices together
- You need a familiar small business accounting platform
- You want software that can grow beyond VAT filing
The main watch-out is plan fit. Check the exact plan before signing up, because accounting features, VAT tools and support options can vary.
Do not choose VAT filing software only because it is cheap. A lower monthly cost can disappear quickly if your accountant spends extra time fixing records before each VAT deadline.
5. Sage
Sage is a strong option for businesses that want established accounting software with structured VAT tools. It may suit businesses that prefer more control over VAT rates, reports and accounting settings.
Sage says its VAT software lets businesses choose VAT rates, run reports, submit returns online to HMRC and give accountant access. It also says users can see dashboard views of VAT owed or owed back.
Sage strengths
- Established accounting software brand
- Good for structured finance processes
- VAT rate settings
- Direct VAT return submission
- Monthly VAT position visibility
- Suitable for businesses that want more control
Sage may suit you if:
- You want a recognised accounting platform
- You need more structured bookkeeping processes
- You have an internal finance person
- You prefer a system with strong accounting controls
The main drawback is usability for very small businesses. Some owners may find Sage more formal than lighter tools like FreeAgent or VAT-only software.
6. Zoho Books
Zoho Books is worth considering if your business already uses Zoho apps or wants accounting software with a broad set of finance features. It can be a practical option for small businesses that want VAT filing alongside invoicing and expense tracking.
Zoho says its MTD-compliant accounting software helps businesses file VAT and Income Tax returns directly to HMRC. It also includes invoicing, expense recording and HMRC connection features.
Zoho Books strengths
- Useful if you already use Zoho tools
- VAT filing inside a wider accounting system
- Invoicing and expense features
- Good for cost-conscious businesses
- Cloud-based access
- Broad business software ecosystem
Zoho Books may suit you if:
- You already use Zoho CRM or other Zoho apps
- You want accounting software at a lower entry cost
- You are comfortable managing setup yourself
- You do not need every accountant to know the platform already
The main watch-out is accountant familiarity. Many UK accountants work more often with Xero, QuickBooks, FreeAgent or Sage, so check whether your accountant supports Zoho Books before switching.
7. Swift VAT Pro
Swift VAT Pro is a good option if you want VAT-only filing rather than full accounting software. It may suit sole traders, small businesses or accountants who already keep records elsewhere and only need a direct VAT submission tool.
Swift VAT Pro says it is HMRC-recognised MTD VAT software for UK sole traders, small businesses and accountants. It lets users export VAT data from an existing system, upload it and submit the VAT return directly to HMRC.
Swift VAT Pro strengths
- Focused on VAT filing
- Useful for VAT-only needs
- Direct submission to HMRC
- Simple compared with full accounting platforms
- Suitable for spreadsheet-led businesses
- May suit accountants managing VAT submissions
Swift VAT Pro may suit you if:
- You only need VAT return filing
- You already keep records elsewhere
- You do not need full bookkeeping software
- You want a focused tool without extra accounting features
The main drawback is that VAT-only software may not solve wider bookkeeping issues. If your records are messy, full accounting software or accountant support may save more time.
Which VAT filing software should you choose?
Choose VAT filing software based on how your business actually works. A simple sole trader, a VAT-registered ecommerce company and a growing limited company will not need the same setup.
Your business need | Best fit |
Best all-round accounting and VAT platform | Xero |
Software with accountant collaboration through Sleek | SleekBooks |
Freelancer or contractor with simple records | FreeAgent |
Existing QuickBooks user | QuickBooks |
More structured accounting controls | Sage |
Zoho ecosystem user | Zoho Books |
VAT-only filing from existing records | Swift VAT Pro |
Start with two questions:
- Do you need full bookkeeping software, or only VAT return submission?
- Do you want to manage VAT yourself, or have an accountant review before filing?
If you want professional support, Sleek’s guide to choosing a VAT specialist accountant explains what to check before choosing a provider.
Can VAT filing software replace an accountant?
VAT filing software can reduce admin, but it does not replace judgement. You are still responsible for using the right VAT treatment, keeping accurate records and submitting correct figures.
Software can help with calculations, reminders and record keeping. An accountant can help with VAT schemes, unusual transactions, imports, exports, VAT refunds, corrections and HMRC queries.
This matters if your business deals with:
- Mixed VAT rates
- International sales
- Imports or exports
- VAT refunds
- Late returns
- Large purchases
- Property transactions
- Complex expense claims
Sleek’s types of VAT guide explains the main VAT categories small businesses should understand before filing.
When is VAT filing software not enough?
VAT filing software may not be enough if your transactions need interpretation before they are entered. Software can process data, but it cannot always decide the correct VAT treatment for unusual transactions.
You may need accountant support if:
- You sell to customers outside the UK
- You buy or sell services internationally
- You are unsure when to charge VAT
- You make large business purchases
- You need to correct a previous VAT return
- You have missed a VAT deadline
- You use different VAT rates
- You have poor or incomplete records
Sleek’s guide on when not to charge VAT explains common situations where VAT treatment may need closer review.

FAQs on best VAT filing software UK
How does VAT software connect to HMRC?
VAT software connects to HMRC through an API, which lets your software send VAT return data from your digital records. You usually authorise the connection through your HMRC account, then the software can file returns without manual copying. GOV.UK explains this in its guidance on software compatible with Making Tax Digital for VAT.
Which VAT software is HMRC-approved?
HMRC does not usually use the word “approved” in the way software providers often do. The more accurate term is Making Tax Digital-compatible software. Before choosing a tool, check whether it appears on HMRC’s list of VAT-compatible software and bridging software, especially if you need to keep digital records and submit VAT returns directly.
What’s the difference between accounting software and VAT software?
Accounting software covers wider finance tasks, such as invoicing, expenses, bank reconciliation, reporting and accountant access. VAT software may only help you prepare and submit VAT returns. Some businesses need full accounting software because VAT depends on clean bookkeeping. Others can use VAT-only or bridging software if their records are already maintained elsewhere.
How secure is VAT filing software?
Secure VAT filing software should protect HMRC access, financial records and user permissions. Check whether the provider offers two-factor authentication, role-based access, data backups and clear controls for removing users. This matters if staff, bookkeepers or accountants access the same records, because weak permissions can expose sensitive financial data or allow changes without proper review.
Is free VAT software available in the UK?
Free VAT software is available in some cases, but it often comes with limits on features, support, transaction volumes or integrations. It may work for very simple VAT-only filing, especially if your records are already clean. Growing businesses usually need paid software for bank feeds, accountant access, better reporting and support before filing deadlines.

Is cloud-based or desktop VAT software better?
Cloud-based VAT software is usually better for small businesses that want remote access, bank feeds and easier accountant collaboration. Desktop software may suit businesses with older internal systems or strict local setup preferences. If you are comparing options, Sleek’s online accounting guide explains how cloud accounting works for small businesses.
How easy is it to switch VAT software providers?
Switching VAT software is usually manageable if your records are clean and you avoid changing systems close to a VAT deadline. You may need to export historical data, check opening balances, reconnect HMRC authorisation and test the next return. Ask your accountant to review the first filing after switching, especially if you use bank feeds or VAT schemes.
