SG Tax & Payroll — Cowork Plugin

This pack reduces the scramble around payroll, GST, and year-end reporting by turning Xero data or employee CSVs into organised handoff materials. It calculates payroll-related figures, prepares payslips, and assembles packets your accountant can review more easily. The business benefit is fewer deadline surprises, less manual consolidation, and a cleaner preparation process while keeping filing and tax advice with your accountant.

• You're running monthly payroll and need CPF, SDL, and payslips.
• A GST or IRAS deadline is coming up (F5, ECI, Form C-S/C, IR8A).
• You're compiling materials to hand to your accountant.

1. 1Say a trigger like "run payroll", "calculate CPF", "prepare my GST return", or "year-end tax prep".
2. 2Claude works from Xero or a simple CSV employee list and produces the figures and documents.
3. 3Review the packet, then forward it to your accountant for filing.

• cpf-payroll

  Monthly payroll prep — calculates CPF by age and residency, computes SDL, generates MOM-compliant payslips, and compiles year-end IR8A.

• tax-prep

  The command version — GST F5 prep or year-end corporate tax + IR8A, ending in an accountant handoff packet.

• tax-season-organizer

  Two modes — GST return (F5) prep with ECI reminders, or year-end corporate tax (Form C-S/C) and IR8A/AIS employee reporting.
