Crossing the VAT line is not just an accounting event. For small cafes and restaurants, it is usually a pricing and cash-flow event on the same week.

If you wait for quarter-end to adjust, the first shock already happened.

Quick Take

GOV.UK threshold: VAT registration is required when taxable turnover is more than GBP 90,000.
Businesses below that level can still register voluntarily.
UK CPI was 3.0% in December 2025, with restaurants and hotels at 3.8% (ONS, released 15 January 2026).
BCC’s January 2026 survey: 63% cite tax as a concern, 52% expect price increases.

This is why VAT-threshold planning is now a margin-control task, not just compliance admin.

The Core Weekly Formula

Weekly net VAT exposure = Output VAT - Input VAT

Weekly VAT reserve transfer = max(0, Weekly net VAT exposure)

Keep this reserve outside day-to-day operating spend.

Worked Example (Cafe, Week Snapshot)

Assumptions:

VATable sales (gross): GBP 12,000
Output VAT included in sales: GBP 2,000
Input VAT on eligible purchases: GBP 540

Weekly net VAT exposure = 2,000 - 540 = GBP 1,460

If this GBP 1,460 is treated as operating cash, margin looks better than reality.

What to Reprice First

Start with items where these three overlap:

low contribution before VAT effect
high labour minutes
weak add-on capture

Protect your clear value anchors, but do not protect loss-making anchors indefinitely.

Threshold-Crossing Checklist (14 Days)

Confirm threshold status and registration timing on GOV.UK rules
Rebuild top 20 item contribution with VAT-aware assumptions
Set weekly VAT reserve transfer rule
Update POS tax settings and invoice logic
Align menu board, online menu, and delivery channels
Brief FOH script: short, factual, non-defensive

FOH Script (Simple)

“We’ve updated selected prices to reflect current operating and tax costs. Core staples are still positioned for value.”

Short clarity beats long apology.

Common Mistakes

Treating threshold crossing as bookkeeping only
Absorbing VAT impact across all menu items without triage
Mixing VAT reserve and supplier-payment cash
Updating POS later than menu communication

Frequently Asked Questions

When do UK food businesses need to register for VAT?

GOV.UK says businesses must register when VAT-taxable turnover is more than GBP 90,000, and can choose voluntary registration below that level.

Why does margin feel worse after crossing the threshold?

Because output VAT, pricing psychology, and cash timing all change at once. If menu math is not rebuilt quickly, cash and contribution can both tighten.

Can I keep the same customer prices and absorb VAT?

You can, but many operators see contribution compression if they absorb the full VAT impact on already-thin items.

What is the fastest control metric to add this week?

Track weekly net VAT exposure (output VAT minus input VAT) and transfer a reserve before discretionary spending.
