Give Claude deep UK accounting knowledge. This plugin replaces the generic finance responses with regulation-aware workflows built specifically for British businesses. It covers journal entries under FRS 102, VAT reconciliation with 9-box MTD returns, Companies House filing (annual accounts, confirmation statements, audit exemption rules), payroll with employer NIC and auto-enrolment pension calculations, and month-end close management with HMRC deadline tracking. Built on and derived from Anthropic's official Finance & Accounting Plugin. Every US-specific element has been replaced with verified UK equivalents: FRS 102 instead of US GAAP, HMRC VAT and Making Tax Digital instead of US sales tax, employer NIC and auto-enrolment pension instead of FICA and 401(k). Four entirely new skills (VAT Reconciliation, MTD Filing, Companies House, PAYE/RTI Payroll) cover workflows that have no US equivalent. Designed for sole traders, freelancers, SMBs, and their accountants. Includes 12 skills across 8 slash commands, references only verified FRS 102 standards and HMRC guidance, and ships with 2025/26 tax year rates. Connects to Xero, Sage, FreeAgent, Open Banking, and HMRC MTD API via MCP.
