Sales commission paid to a UK employee is taxed under PAYE - no VAT applies. Sales commission paid to a UK-registered self-employed sales contractor IS subject to VAT if the contractor is VAT-registered, and the commission becomes recoverable input VAT for the paying business. The treatment changes materially between employee and contractor structures, and sales operations teams routinely miss this when restructuring commission models.
Sales commission paid to a UK employee is taxed under PAYE; no VAT applies. Sales commission paid to a UK-registered self-employed sales contractor IS subject to VAT if the contractor is VAT-registered. The treatment changes materially between employee and contractor structures, and sales operations teams routinely miss this when restructuring commission models.
Three specific traps:
Reclassifying employees as contractors without VAT planning. Some firms shift sales staff from PAYE to contractor status to reduce employer NI cost. If the contractor is VAT-registered, their commission invoice now includes 20 percent VAT on top. The receiving business reclaims the VAT as input tax (so net cost is similar) but cash flow timing changes and the VAT-registration administration overhead is real.
Contractor commission with overseas customers. UK VAT rules for cross-border B2B services have specific place-of-supply rules. A UK contractor invoicing commission for a sale to an EU or non-EU customer may be outside the scope of UK VAT (or subject to reverse-charge). The treatment depends on the customer's location and registration status; the wrong treatment produces over-collection or under-collection of VAT.
SDR / inside-sales commission paid through a referral or affiliate structure. Where commission is structured as a 'referral fee' rather than employment compensation, VAT applies to the referrer if they're VAT-registered. The structure matters; getting it wrong produces HMRC adjustments at audit.
The implication for UK sales operations teams in 2026: any commission structure beyond standard PAYE-employee should run through finance and (where material) external tax advice before deployment. The cost of getting it wrong is 20 percent of the commission flow plus interest and penalties; the cost of getting it right is hours of upfront planning.
This is an editorial signal, not tax advice. Consult a chartered tax adviser or HMRC for your specific structure.
Snapshot
UK B2B outbound channel mix has shifted materially from 2022 to 2026: LinkedIn first, phone returning, cold email lower-volume but more personalised, direct mail seeing a small revival in enterprise. The relative effectiveness ranks have inverted from the 2022 hierarchy.

Account-based sales (ABS) was promoted heavily across UK SaaS through 2018-2023 as a structural answer to broad-volume outbound. By 2026 the picture is more nuanced: ABS works at specific deal sizes and team scales, fails predictably outside those, and many UK mid-market teams adopted it for the wrong reasons. A practitioner walkthrough.

UK enterprise buyers in 2026 increasingly run ESG due diligence on vendors as part of procurement: documented sustainability commitments, modern-slavery statement, supply-chain transparency, and (depending on the buyer) climate-disclosure alignment. The UK Sustainability Disclosure Standards regime has tightened the buyer-side disclosure obligations, which cascades down to vendor expectations.
