Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (2)

estimate_cis_refundread-only Estimate a UK CIS subcontractor's tax refund (or amount to pay) for tax year 2025-26, 2026-27 or 2027-28 (Budget 2026 rules for 2027-28). Takes the year's gross CIS income, the CIS deducted (the statement total, or the 20%/30% rate), allowable expenses (materials, tools, van mileage at HMRC simplified rates, parking and travel, phone, protective clothing, training and site cards, insurance, accountant) and optional other PAYE/pension income. Calculates taxable profit (or the trading allowance if better: £1,000, or £3,000 from 2027-28), income tax (England/Wales/NI or Scottish bands, Personal Allowance taper), Class 4 NIC and the Class 2 position, then compares the bill with the CIS already deducted. Returns the working line by line, payments-on-account warning, commonly missed expenses, rates used with GOV.UK sources and a result card. For self-employed sole traders under CIS, not limited companies. Read-only: stores and sends nothing. An estimate, not tax advice.

get_cis_tax_ratesread-only List the UK rates a self-employed CIS subcontractor's tax bill uses for 2025-26, 2026-27 or 2027-28, each with its GOV.UK source: Personal Allowance and taper, income tax bands (England/Wales/NI or Scotland), Class 4 NIC limits and rates, the Class 2 position (treated as paid above the Small Profits Threshold, voluntary below), HMRC simplified mileage rates, the trading allowance (£1,000; £3,000 from 2027-28), the Making Tax Digital start dates and the 20%/30% CIS deduction rates. Read-only. Not tax advice.
