Import Duty & VAT Calculator (UK)
UK duty on customs value plus import VAT on the duty-inclusive total — the post-Brexit UKGT math.
Duty applies to the CIF customs value per the UK Global Tariff; import VAT applies to value + duty + certain UK-side costs. VAT-registered businesses typically use Postponed VAT Accounting instead of paying at the border.

Post-Brexit UK import math runs on the UK Global Tariff: duty applies to the customs value (CIF — goods, freight and insurance to the UK border), then import VAT applies to the duty-INCLUSIVE total plus certain UK-side costs like onward freight to the first destination. The compounding matters: 20% VAT on (value + duty) means a 4% duty item carries an effective ~24.9% charge at the border, not 24%.
About Import Duty & VAT Calculator (UK)
Two regimes change the cash reality. The UK–EU Trade and Cooperation Agreement zeroes duty on goods of EU (or UK) ORIGIN — origin meaning the TCA's rules of origin are met and stated, not merely that the goods shipped from the EU; re-exported Chinese goods via Rotterdam pay full UKGT. And Postponed VAT Accounting lets VAT-registered importers account for import VAT on the VAT return instead of paying at the border — the VAT line in this calculator becomes a bookkeeping entry rather than a cash payment, which transforms working capital for regular importers. Rates live in the UK Integrated Online Tariff by commodity code — UKGT rates were deliberately simplified versus the EU's (many low nuisance rates rounded to zero), so checking your specific code pays. The £135 threshold also reroutes small consignments: below it, VAT is collected at the point of SALE (seller/marketplace registers) rather than at the border, and duty doesn't apply.

Frequently asked questions
How is UK import VAT calculated?+
On the augmented base: customs value (CIF) + duty + excise (if any) + certain post-arrival costs (onward transport to first UK destination, insurance for that leg). At standard 20%: £20,000 CIF with £800 duty and £400 incidentals → VAT on £21,200 = £4,240. The calculator mirrors that base; VAT-registered traders reclaim or postpone it, making duty the only true cost.
What is Postponed VAT Accounting (PVA)?+
The post-Brexit mechanism letting VAT-registered importers declare AND reclaim import VAT on the same VAT return — no cash at the border, no C79 wait. You opt for it on the customs declaration; the monthly postponed-VAT statement supports the return entries. For most businesses it's strictly better than paying at clearance: same net VAT, radically better cash flow.
Are EU goods duty-free into the UK?+
Only ORIGINATING goods: the TCA gives zero tariffs where the goods meet its rules of origin and a statement on origin (or importer's knowledge) supports the claim. EU-warehouse stock of Asian manufacture fails origin and pays full UKGT — the single most common post-Brexit surprise. The claim also needs the supplier's origin statement wording on the invoice; no statement, no preference.
What happens below £135?+
The border charge disappears and the obligation moves to the seller: consignments ≤£135 (intrinsic value) have no customs duty, and VAT is charged at the point of sale — overseas sellers and marketplaces must register for UK VAT and charge it at checkout. B2B with a UK VAT number reverse-charges instead. Above £135, normal border math (this calculator) applies.
