Most business owners know they need to charge VAT on their sales. Where it gets confusing is knowing when that VAT needs to be reported to HMRC. Get the date wrong and you could end up accounting for VAT in the wrong period, which means penalties, corrections and unnecessary stress. The answer sits in understanding two concepts: the basic tax point and the actual tax point. These are the legal rules that determine the exact date a transaction is treated as having taken place for VAT purposes. Once you understand how they interact with invoices, payments and deposits, the whole system becomes much more straightforward. This article explains both rules clearly, including what happens when invoices are late or a deposit is taken.

What is a basic tax point?
The basic tax point is the default starting position under VAT law. For goods, it’s the date the goods are sent to or collected by the customer. If the goods aren’t dispatched because they’re being assembled on-site, the basic tax point is the date they’re made available for the customer to use. For services, it’s the date the work is physically completed, which in practice usually means the date everything is finished except the invoice. Most business owners assume the invoice date is what matters. It’s a natural assumption, but the law starts somewhere different and the invoice date only takes over once specific conditions are met.

What creates an actual tax point, and how does it override the basic one?
An actual tax point replaces the basic tax point entirely. Two things create one. First, if a VAT invoice is issued or payment is received before the basic tax point, the earlier of those two dates becomes the actual tax point. So if you invoice a client before delivering the goods, the invoice date is when the VAT clock starts, not the delivery date. Second, if you issue a VAT invoice within 14 days of the basic tax point, the invoice date becomes the actual tax point. This 14-day window exists to give businesses a practical buffer between completing work and raising the paperwork. Businesses that routinely bill on a monthly cycle can apply to HMRC for an extension to this 14-day limit, which is worth knowing if your invoicing runs on a calendar month rather than job by job.

What happens if the invoice goes out more than 14 days after the work is done?
If a VAT invoice is issued more than 14 days after the basic tax point, and there’s no prior HMRC approval in place to extend that window, the tax point reverts to the basic tax point. That means the VAT should have been reported in an earlier period than the invoice date suggests. For businesses that don’t invoice promptly, this creates a real risk of reporting VAT late without realising it. The fix is straightforward: either tighten up invoicing timelines so invoices go out within 14 days of completing the work, or apply to HMRC for permission to use an extended tax point arrangement. Ignoring it isn’t an option once HMRC spots the pattern on a VAT visit.

How do deposits fit into this?
A deposit is an advance payment for a supply that hasn’t happened yet. The moment a deposit is received, an actual tax point is created. Output VAT must be accounted for on the deposit at that point, not when the remaining balance is paid or when the goods or services are eventually delivered. This catches a lot of businesses out, particularly those in construction, events or tailored manufacturing where deposits are standard practice. It’s also worth knowing that not all deposits work the same way. Security deposits and stakeholder deposits can be treated differently depending on the circumstances, so if your business takes a variety of upfront payments, it’s worth getting specific advice rather than applying a blanket rule.

Why does this matter right now?
HMRC’s compliance activity around VAT has increased steadily, with more targeted checks on VAT return accuracy and timing. The VAT gap, which is the difference between what HMRC expects to collect and what it actually receives, remains a priority for the department. Errors in time of supply are one of the more common findings on VAT inspections, particularly in businesses where invoicing is inconsistent or where deposits are common. Getting this wrong doesn’t automatically mean a penalty, but it does mean corrections, potential interest on late-declared VAT and, if it’s a pattern, the possibility of a more detailed inquiry. Understanding the rules now, before any review, is a much better position to be in.

What should you do if you’re unsure where your business stands?
Start by mapping out how your business actually invoices. Note the gap between completing work and raising the invoice, and check whether that gap regularly exceeds 14 days. If it does, speak to your accountant about applying to HMRC for an extended tax point arrangement before it becomes a problem on a VAT inspection. If your business takes deposits, make sure VAT is being accounted for at the point the deposit is received rather than when the final invoice goes out. These are small process adjustments that make a significant difference to your VAT compliance.
