Chennai imports, customs, and Section 16 ITC

Chennai's port commissionerate processes Bills of Entry for traders pulling components from China, Vietnam and the EU. Each bill of entry shows BCD (basic customs duty, non-creditable), social welfare surcharge (10% of BCD, non-creditable), and IGST on the assessable value plus BCD plus SWS — and only the IGST portion is creditable as input tax, claimed in GSTR-3B Table 4(A)(1) on the date the BOE is filed and goods are received. HelloBooks tracks the BOE number, BOE date, port code, and the IGST split per line so the ITC claim is auto-populated, the BCD goes to landed cost on the inventory item (not to a P&L expense), and the SWS rolls into duty cost.

For SEZ supplies and exports out of Chennai, the workflow mirrors the rest of India — LUT-based zero-rated supplies under Rule 89 for refund-of-ITC, or with-tax exports under Rule 96 for refund-of-tax. Tamil Nadu's SEZ footprint is concentrated in Sriperumbudur, MEPZ Tambaram, Madras Export Processing Zone and Nokia SEZ; HelloBooks tags SEZ buyers and exporters at the customer level and assembles the refund pack from the same record.

Coimbatore engineering, Tiruppur knitwear, and Salem steel

Coimbatore's engineering cluster — pumps, motors, wet-grinders, foundries — runs on multi-level BOMs, work orders and capital-goods ITC. Capital goods bought after July 2017 are eligible for full ITC at the time of purchase (subject to Rule 43 reversal if the asset is later used for exempt supplies), and depreciation under the Income-tax Act has to be claimed only on the value net of ITC. HelloBooks handles the ITC claim, the Rule 43 monthly proportionate reversal where applicable, and the income-tax depreciation base correctly — three calculations that small Coimbatore accountants often manage in three different spreadsheets.

Tiruppur's knitwear cluster is India's largest cotton-garment exporter, almost entirely export-focused. The workflow is LUT-based: raw cotton is bought with ITC at 5%, processed into garments at 5% (below ₹1,000) or 12% (above), and exported zero-rated under LUT. Refund-of-accumulated-ITC under Rule 89(5) is filed quarterly — Tiruppur exporters are among the heaviest users of inverted-duty-structure refunds in India because their input rate often exceeds their output rate. HelloBooks builds the Rule 89(5) refund pack from the same purchase-invoice and export-invoice data without a separate spreadsheet exercise.

CTPT, payroll, and CTD Tamil Nadu compliance

Tamil Nadu Profession Tax (CTPT) is levied under the Tamil Nadu Municipal Laws (Second Amendment) Act, 1998 — so unlike Maharashtra or Karnataka, profession tax in Tamil Nadu is collected by the local body (corporation, municipality or panchayat) on a half-yearly basis instead of a state-level monthly cycle. The slabs differ slightly across corporations, but the typical Chennai Corporation slab is zero up to ₹21,000/half-year, ranging up to ₹1,250/half-year above ₹75,000. HelloBooks computes CTPT inside India payroll at the right corporation's slab, generates the half-yearly challan, and tracks the September and March windows. The rest of statutory payroll — PF, ESIC, gratuity, FBP, Form 16, Form 24Q — runs the same as anywhere else in India.
