Yes, bookkeepers can prepare and submit VAT returns, especially if they’re experienced and familiar with your accounting software. However, an accountant will usually offer deeper tax insights and check for errors or missed claims. For peace of mind and full compliance, many businesses choose an accountant to review or file the return.
The cost of a VAT return varies depending on your business and how complex your records are. Some accountants offer it as a one-off service, while others include it in a monthly package. It’s best to speak to an accountant who can give you a clear idea based on your needs and help make sure everything is done correctly.
Yes, both QuickBooks and Xero can generate and submit VAT returns directly to HMRC under Making Tax Digital. They’re handy tools but rely on your bookkeeping being spot on. To avoid mistakes or missed claims, it’s a good idea to have an accountant review things before you file, especially if your VAT is a bit more complex.
Generally, yes. Most professional services, such as legal, consulting, or accounting, are subject to VAT at the standard rate if the provider is VAT-registered. There are a few exceptions depending on the sector or nature of the work, so it’s always best to check your specific case with an accountant.
No, accounting services are typically standard-rated for VAT. That means if your accountant is VAT-registered, they’ll add VAT to their invoice. You may be able to reclaim it if you’re VAT-registered too. If you’re unsure how this works for your business, we can walk you through it.
Some services are exempt from VAT, such as insurance, education, health services, and some financial products. These vary based on how and where the service is provided. If you’re not sure whether your service is exempt, we can review it and help you stay on the right side of HMRC.
