Mileage + 6 categories + receipts

Business mileage (HMRC 45p/25p auto-split), materials, tools/PPE, phone, training, subsistence, other. Snap receipts from your phone camera. Everything drops your set-aside in real time.

CIS mode

Construction 20% / 30% + materials split

Registered subbies: 20% (or 30% unregistered) at source. Log materials/plant hire inline on the pay period card — HMRC exempts them from CIS, Clok shows exactly what you save.

Set aside tracker

Class 4 NI + Income Tax, live

Every shift you log, Clok annualises your profit and shows the running HMRC bill. When CIS is deducted at source or expenses log, "set aside remaining" drops so you know what to keep back.

HMRC mileage

45p for the first 10k. 25p after.

Simplified Expenses done right. Clok tracks the 10,000-mile threshold across the tax year — cross it mid-year and the rate drops on the next log automatically.
