SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Malaysian companies face penalties from LHDN and RMCD when SST-02 returns, CP204 instalment estimates, or Form C annual filings are missed, late, or materially inaccurate. This Skill tracks every filing obligation, computes tax liabilities from existing accounting data, and flags penalty risks before deadlines pass. ## Core Features & Use Cases - SST-02 Return Preparation: Computes output tax on taxable supplies per bimonthly period, checks claimable input tax, and produces a net SST payable summary with the correct due date. - CP204 Estimate Monitoring: Estimates current-year corporate tax from YTD P&L, applies the correct statutory rate, and flags when the estimate deviates from prior-year tax by more than 30% so a CP204C revision can be filed. - Form C Annual Compliance: Adjusts full-year P&L for non-deductible items, reconciles tax payable against CP204 instalments, and records the e-Filing deadline. - Use Case: A finance manager preparing the Jul-Aug SST-02 return pulls sales invoices for the period, computes RM18,500 output tax, confirms the 30-Sep due date, and verifies the CP204 estimate is within the 30% variance threshold. ## Quick Start Ask the finance-manager agent to prepare the SST-02 return for the current taxable period and check the CP204 estimate against last year's tax.

Frequently Asked Questions about tax-sst-compliance

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I prepare an SST-02 return in Malaysia?

Determine the bimonthly taxable period, pull sales invoices for that period to compute output tax on taxable supplies, check any claimable input tax, then compute net SST payable. The return is due by the last day of the month following the taxable period.

How to check if a CP204 tax estimate needs revision?

Compare the current-year estimated tax against the prior-year actual tax. If the estimate deviates by more than 30%, LHDN may impose a 10% penalty on the shortfall, so file a CP204C revision by the ninth month of the financial year.

What accounting data does this skill need to compute tax filings?

It uses existing acct_* MCP contract tools: acct_get_profit_loss for P&L data, acct_list_sales_invoices for taxable supplies, and acct_list_purchase_bills for input tax. No new tax-agency integration is required.

When is the Form C filing deadline for Malaysian companies?

Form C must be e-Filed within 7 months of the financial year end. The skill computes adjusted chargeable income, reconciles against CP204 instalments paid, and records the deadline in the compliance calendar.

When should I not use this tax compliance skill?

Do not use it for MFRS 15 revenue recognition questions, which belong to the mfrs15-revenue-recognition skill, or for SST treatment on reimbursed expenses, which is handled by the expense-claim-audit skill.
