The stress pattern is predictable: service is busy, then deadline week hits, and cash suddenly feels short.
Most of the time, that is not a sales issue. It is a reserve cadence issue.
Quick Summary
- HMRC VAT due date is usually
period end + 1 month + 7 days - PAYE is usually due by the
22ndmonthly when paid online - Build tax reserves weekly, not at month-end
- Keep VAT and PAYE buckets separate from operating cash
Why This Matters in 2026
ONS reported UK restaurants and hotels inflation at 3.8% in the December 2025 CPI release (published January 21, 2026). ONS business insight data (published July 31, 2025) also showed that businesses most often cited inflation (17%) and taxation/labour costs (16%) as concerns.
When operating costs stay elevated, one missed tax cycle can wipe out a month of pricing gains.
The Weekly Reserve Model
Use two reserve buckets:
VAT bucket(quarterly cadence for many small operators)PAYE bucket(monthly cadence)
weeklyVATReserve = expectedQuarterlyVAT / 13
weeklyPAYEReserve = expectedMonthlyPAYE / 4.33
totalWeeklyTaxTransfer = weeklyVATReserve + weeklyPAYEReserve
This turns tax into routine cash movement instead of emergency funding.
Worked Example
Assume:
- Expected quarterly VAT payment:
£11,700 - Expected monthly PAYE payment:
£2,600
weeklyVATReserve = 11,700 / 13 = £900.00
weeklyPAYEReserve = 2,600 / 4.33 = £600.46
totalWeeklyTaxTransfer = 900.00 + 600.46 = £1,500.46
Round up and transfer £1,525 weekly.
That small buffer protects against estimate error.
Deadline Calendar Setup (Operator Version)
- Put each VAT due date in your calendar at period start.
- Add monthly PAYE reminders for the 15th (internal check) and 22nd (payment deadline).
- Automate one weekly transfer into each reserve bucket.
- Re-estimate reserve amounts on the final day of each month.
Common Mistakes
- Waiting until the due week to calculate cash needed
- Mixing reserve cash with daily operating account balance
- Using last quarter values without current payroll trend
- Treating tax reserve as “leftover” instead of fixed weekly transfer
10-Minute Friday Checklist
- VAT bucket on track for next due date
- PAYE bucket on track for next month
- Payroll hours trend updated
- One corrective transfer made if short
Bottom Line
Deadline pressure is not random. It is predictable cash timing.
If you run pricing by item and reserves by week, VAT/PAYE months stop feeling like shocks.
