Reclaiming UK Import VAT on Freight: Understanding C79 Certificates and PVA

A UK e-commerce business importing stock from non-UK suppliers (typically China, but also EU, US, Vietnam, India) pays import VAT to HMRC when the goods clear UK customs. The VAT is fully recoverable as input tax on the next VAT return, but the timing differs sharply depending on which route the seller uses. Postponed VAT Accounting (PVA) handles the VAT on the same VAT return without any cash outlay. C79 certificates require the seller to physically pay the VAT at the border and recover it on the following return, typically 1-3 months later.

This piece walks both routes, the cash-flow maths for a typical £500k-per-year stock buyer, the monthly statement mechanics, and the reconciliation pitfalls. Sister pieces in [the cross-border VAT hub](/guides/cross-border-ecommerce-vat-ioss/) cover [IOSS for EU-bound B2C](/blog/import-one-stop-shop-ioss-uk-sellers/) and [Pan-EU FBA local VAT registrations](/blog/pan-eu-fba-local-vat-registrations/).

How import VAT works at the UK border

When goods are imported into the UK from outside the UK, import VAT is due at the standard rate (20% for most goods) on the customs value plus any duty. The customs value is the price paid for the goods plus freight, insurance, and any other costs of delivery to the UK border. A £10,000 shipment of stock from China with £500 freight pays import VAT on £10,500, so £2,100 of import VAT.

The C79 route

Under the C79 mechanism, the importer (or their freight forwarder) pays the import VAT to HMRC at the time of customs clearance. HMRC sends a monthly C79 certificate showing all import VAT paid in the month. The importer reclaims that VAT as input tax on the next VAT return after the C79 month. A January import with VAT paid at the border generates a January C79, which feeds into the input tax box on the Q1 (Jan-Mar) return filed by 7 May. The cash leaves the business in January and comes back in May, a four-month timing gap.

On a £500,000 annual stock buy with £100,000 of import VAT, the C79 route ties up £25,000 to £35,000 of working capital at any given time (varying with stock turnover). For a brand growing 50% year on year, the working capital tied up in import VAT grows in lockstep with stock orders, often consuming cash precisely when the brand most needs it for marketing and team.

The PVA route

Postponed VAT Accounting moves the import VAT entirely onto the VAT return. The importer's customs declaration flags PVA. No VAT is paid at the border. The amount that would have been paid is "postponed" into the input tax and output tax sides of the next VAT return; the two cancel out for a fully-recoverable importer. The result: zero cash outlay for import VAT, ever.

For the same £500k stock buyer, PVA frees up £25,000-£35,000 of working capital permanently. This is consistently the single most impactful cash-flow improvement available to mid-volume UK e-commerce brands, and the only reason to be on C79 rather than PVA in 2026 is administrative inertia.

C79 vs PVA: side-by-side

Setting up PVA

• Register an HMRC Government Gateway account for the business if not already done.
• Enrol for the PVA service through the gateway (linked to the EORI number).
• Instruct the freight forwarder or customs broker to use PVA on all incoming declarations.
• Download the PVA Monthly Statement from HMRC each month (typically available by the 10th of the following month).
• Reconcile the statement against the accounting records; post the gross VAT amount to both input tax and output tax lines.
• Submit the VAT return as normal; the two postings net to zero impact.

Reconciliation pitfalls

PVA Monthly Statements occasionally show imports the business does not recognise (typically samples or replacements that the supplier shipped without notifying the buyer's accounts team). C79 certificates can be incomplete or arrive months late through the postal system. Either way, the input tax claim must match what HMRC sees: claiming VAT not on a C79 or PVA statement is the most common ground for HMRC to disallow input tax on a VAT inspection. Monthly reconciliation against the official statement is non-negotiable for high-volume importers.

When to use C79 instead of PVA

The remaining use case for C79 is one-off imports by businesses not registered for VAT (where the import VAT is a cost, not recoverable), or imports through Royal Mail and certain postal channels where PVA is not currently supported. For any regularly importing VAT-registered business, PVA is the default in 2026.

My freight forwarder defaults to C79. How do I switch?

Email the freight forwarder confirming the EORI number and instructing all future declarations to use PVA (customs declaration method of payment code "G"). Most major UK forwarders (DHL, Kuehne+Nagel, DSV, OIA Global) handle the switch on the next clearance. Smaller specialist forwarders may need explicit per-shipment instruction. Confirm the switch by checking the next PVA Monthly Statement against expected imports.

Can I retroactively recover VAT on old imports I missed?

Yes, within four years. Input tax under-claimed on previous VAT returns can be corrected on the current return up to four years after the original return's due date. The maximum correction without a formal error report is £10,000 net of corrections per return; larger errors require a formal VAT 652 disclosure. For brands that have been operating without recovering import VAT properly, a back-claim exercise frequently surfaces £20,000-£60,000 of recoverable VAT.
