A £45,000 CIF Felixstowe shipment clears customs. The forwarder sends a clearance confirmation and an invoice. One line reads: import VAT — £9,000. The buyer wires it without questioning the method.
That £9,000 did not need to leave the buyer's bank account.
Postponed VAT Accounting (PVA) allows a UK VAT-registered importer to declare import VAT on the same VAT return that recovers it — Box 1 output, Box 4 input, net cash impact close to zero. But PVA only works if the forwarder elected it on the Customs Declaration Service (CDS) declaration. Forwarders may not elect it by default. The system requires the buyer to instruct the election in writing before each declaration [1]. Without that instruction, the forwarder files a standard declaration, the buyer pays £9,000 upfront, and recovers it weeks or months later through the VAT return cycle.
PVA is a significant cash-flow lever for UK importers. £9,000 on one £45K shipment. Multiply across every import in the quarter. The election takes one written instruction to the forwarder. This article explains what to instruct, how to verify it was done, and what to do if it was not.

For context: where else can you get this
GOV.UK gives the PVA eligibility criteria and the VAT return mechanics — but the guidance is written for customs brokers, not procurement managers [1]. The CDS Tariff Volume 3 gives the Data Element 3/40 field specification — but the buyer cannot tell from the spec what to instruct the forwarder to do [8]. Forwarder briefings explain what happens at clearance — but do not explain why their default declaration setting may not include PVA. This article translates the HMRC guidance into a procurement manager's operational checklist: what to instruct, how to verify, what to fix.
The cash-flow problem PVA solves
Import VAT cash exposure = VAT value × 20%Example: if the VAT value is £45,000, import VAT is £9,000. With PVA correctly instructed, that amount is accounted for on the VAT return. Without it, the buyer may need to fund the cash at clearance and reclaim later.Before PVA existed (pre-1 January 2021), import VAT on a £45,000 shipment at the standard 20% rate worked like this [5]: the importer paid approximately £9,000 to HMRC at the point of customs clearance, then recovered it as input tax on the next VAT return — typically 30 to 90 days later, depending on filing frequency. For a quarterly filer clearing goods in the first week of the quarter, the cash sat with HMRC for up to 90 days.
PVA, introduced on 1 January 2021 as part of the UK's post-Brexit customs arrangements, changed the mechanics [1]. Under PVA, the import VAT is not paid at clearance. Instead, it is declared on the buyer's VAT return: Box 1 records the VAT due, Box 4 records the input tax recoverable [2]. For a fully recoverable import, the net cash impact is close to zero. The £9,000 stays in the buyer's bank account.
The eligibility requirements are straightforward. The business must be UK VAT-registered. It must hold a UK EORI (Economic Operators Registration and Identification) number [4]. No pre-approval is needed — HMRC's guidance states: "You do not need any approval to account for import VAT on your VAT Return" [1]. The election is made per declaration, not as a blanket setting.
CDS Data Element 3/40 — what the buyer tells the forwarder
This is the operational core.
UK customs declarations are submitted through CDS, which fully replaced the older CHIEF system — for imports on 30 September 2022, and for exports by 4 June 2024 [1] [9] [10]. The two systems use different fields. Under CHIEF, PVA was elected using "Method of Payment G" in Data Element 4/8. Under CDS, the procedure changed.
HMRC's current PVA guidance states it directly: "You need to enter your VAT registration number at header level in Data Element 3/40" and — critically — "you should not use method of payment G in Data Element 4/8" [1].
This distinction matters because a meaningful number of forwarder-facing communications, operational guides, and accounting-software help pages have not been updated to reflect the CDS procedure. Any guide that still says "use Method G for PVA" is giving an instruction that is operationally incorrect under CDS.
The buyer's written instruction to the forwarder should say:
"Elect Postponed VAT Accounting on all our import declarations. Use CDS Data Element 3/40 with our VAT registration number [insert number]. Do not use Method of Payment G in Data Element 4/8."
This instruction must exist in writing before the declaration is submitted. HMRC's guidance was updated on 9 June 2025 to strengthen this requirement: the forwarder "must have this written confirmation before they can proceed with the import declaration" [1].
Import VAT vs customs duty vs port charges — what PVA defers and what it does not
PVA defers import VAT only. Three categories of cost arise at clearance, and they are governed by different rules:
Import VAT — calculated at 20% (standard rate [5]) on the customs value plus duty plus certain UK-side incidentals [6]. PVA defers this. Under PVA, the amount appears on the Monthly Postponed Import VAT Statement (MPIVS) rather than as a cash payment.
Customs duty — determined by the 10-digit commodity code on the UK Integrated Online Tariff. Can be 0% to 25% or higher with trade remedies. PVA does not defer duty. Duty is paid at clearance regardless of the PVA election.
Port charges and customs broker fees — handling, entry fees, document processing. Paid to the forwarder or port operator, separate from HMRC. The customs broker fee for a standard CDS import declaration runs £45–£150, depending on volume, complexity, and urgency (benchmark range from UK broker rate cards, 2025–2026) [Class B — benchmark]. PVA does not affect these.
The distinction matters because buyers sometimes assume PVA defers everything at the border. It does not. Only the import VAT line moves from cash payment to VAT return accounting.
The four-step monthly MPIVS reconciliation
The MPIVS is HMRC's official record of import VAT declared through PVA. It is available to download from the CDS portal using the buyer's own Government Gateway login — not the forwarder's or agent's [3]. Statements cannot be accessed using an agent's credentials.
HMRC publishes the MPIVS by the 10th working day of each month [3]. The publication timing has moved over time: it was originally the 6th working day, moved to the 8th in February 2023, and to the 10th in June 2024. Statements are retained online for six months only — after that, they are no longer accessible. Download them every month.
The reconciliation process runs in four steps:
Step 1. Download MPIVS. Log into the CDS portal around the 12th of each month to retrieve the prior month's statement. HMRC publishes by the 10th working day, and statements are only retained for six months, so download and retain your own copy.
Step 2. Cross-check against forwarder statement. Compare every declaration on the MPIVS against the forwarder's monthly clearance statement. Each import should appear on both. If a declaration is missing from the MPIVS, the forwarder may not have elected PVA on that shipment.
Step 3. Map to accounting software. Enter the MPIVS totals into the import-VAT process in your accounting software (Xero, QuickBooks, Sage, or equivalent). The figures feed Box 1 and Box 4 of the VAT return.
Step 4. File the VAT return. Box 1 includes the VAT due on imports accounted for through PVA. Box 4 includes the VAT reclaimed, subject to normal input tax rules [2]. For a fully recoverable import, the two entries net to zero.
Gatekeeper view: what is visible from the China side
The UK customs process is largely invisible to the Chinese supplier. The supplier's commercial invoice — the document filed against Chinese export customs — states a value for the goods. That same invoice is used as the basis for the UK CDS declared value.
In practice, a risk exists when the supplier's Chinese export declaration shows a different value from the UK import declaration. In some cases, a supplier's Chinese export declaration may show a different value for operational, tax or export-documentation reasons. The values do not always reconcile.
This creates a UK audit risk. HMRC can compare the declared customs value against actual payments evidenced by bank transfers. If the declared value is lower than what the buyer actually paid, the import VAT base was understated. If higher, the supplier's Chinese customs filing does not match.
The operational step for the UK buyer is straightforward: insist on consistent invoicing across both jurisdictions. The commercial invoice submitted to the UK forwarder for CDS declaration should match the value on the supplier's Chinese export customs filing. This is a standing instruction to include in purchase-order terms, not a one-off check.
Where this framework breaks
PVA does not apply or only partially applies in five situations.
Buyer is not UK VAT-registered. PVA requires UK VAT registration [1]. Without it, import VAT is paid at clearance and recovered (if applicable) through other mechanisms. This framework does not apply to non-registered importers.
Partially exempt businesses. For businesses that cannot recover 100% of input VAT — common in financial services, education, and healthcare — Box 4 recovery is not complete. The net cash impact of PVA is not zero. Calculate the partial-exemption percentage before assuming the full benefit.
Goods for non-business use. PVA does not apply to imports for personal or non-business purposes [1].
Goods imported via Royal Mail. HMRC states that PVA cannot be used for goods imported using Royal Mail services [1].
Monthly vs quarterly VAT filers. The cash-flow benefit of PVA varies with filing frequency. A quarterly filer who clears goods early in the quarter ties up the VAT for up to 90 days without PVA. A monthly filer ties it up for 30–37 days. PVA eliminates the tie-up entirely for both — but the differential is larger for the quarterly filer.
Forwarder submits declaration without PVA election despite buyer instruction. If PVA was not elected on a specific declaration, the recovery path is not the MPIVS. Instead, the buyer receives a C79 import VAT certificate from HMRC [5], which is used to claim the VAT as input tax on the next VAT return. The C79 is available monthly via the CDS portal. The cash-flow gap still occurred, but the VAT is still recoverable.
Trends layer
As of May 2026, CDS has fully replaced CHIEF for all UK customs declarations — imports since 30 September 2022 and exports since 4 June 2024 [1] [9] [10]. Any operational guide, forwarder briefing, or accounting-software help page that still references "Method G" for PVA election is outdated and operationally incorrect under CDS.
The written-instruction requirement was strengthened in June 2025 [1]. The wording moved from "you should tell them" to "they must have this written confirmation before they can proceed with the import declaration." For UK importers whose forwarder relationship predates this change, the standing PVA instruction may need to be reissued in writing.

Control points before commitment
- Check: do you have a UK EORI number registered against your VAT number? If not, register at GOV.UK [4]. This is required for any CDS declaration.
- Send your forwarder a written instruction. The text: "Elect Postponed VAT Accounting on all our import declarations. Use CDS Data Element 3/40 with our VAT registration number [your number]. Do not use Method of Payment G in Data Element 4/8." Keep a copy.
- Set a monthly calendar reminder for around the 12th of each month. Download the MPIVS from the CDS portal (Government Gateway). Do not wait — statements are only retained for six months [3].
- Cross-check the MPIVS against the forwarder's monthly clearance statement. If a declaration is missing from the MPIVS, the forwarder did not elect PVA on that shipment.
- Map MPIVS totals into your accounting software's import-VAT process — Box 1 (output VAT due) and Box 4 (input VAT recoverable).
