GST Credit Chain Map

A thirteen-entity supply chain at 18% GST across the Sthanam and Gundreddy registrations — nine live GSTINs, three companies being incorporated and one individual still to register — each leg priced at about ₹7,50,000 a month so that every entity's annual turnover stays between ₹95,00,000 and ₹99,90,000, under the ₹1 crore audit line. Every amount you enter is monthly — annual figures are derived at 12 months and shown separately for each entity. The chain is closed — the last position supplies back to the first — so credit circulates and no one sits at a dead end. Profit can only come from sales outside the loop, so each entity also bills an external customer. Use Chain order below to swap positions or bring a new entity in. GST settles monthly through GSTR-3B; income tax follows each entity's own regime.

Basis & assumptions

Every input is monthly. Supply leg values, outside turnover and other cost are monthly amounts. Annual = monthly × months in year (set in the toolbar; default 12). Change the months figure for a part-year contract and every annual column, and the income tax, re-foot.
Credit cascade. Every company that makes an outward supply is assumed registered and eligible for full ITC under Sec. 16 of the CGST Act, so its GST cash outgo each month is tax on value addition only. GST is therefore not a P&L item for it.
Where the tax rests. A company with no outward supply at all — no chain leg out, no outside turnover — cannot use its credit. That ITC shows as a monthly credit pool and is charged to its P&L as GST borne on an annual basis.
Place of supply. Intra-State legs split the rate equally into CGST and SGST; Inter-State legs carry IGST at the full rate. CGST is rounded to the nearest paisa and SGST taken as the balance, so the split always foots.
Income tax is annual. Computed on annual accounting profit before tax with no book-tax differences and no brought-forward losses. Individual — new regime applies the Sec. 115BAC slabs for FY 2025-26 (nil to ₹4,00,000, then 5% / 10% / 15% / 20% / 25% in ₹4,00,000 steps, 30% above ₹24,00,000), the Sec. 87A rebate that wipes the tax on income up to ₹12,00,000 with marginal relief just above it, and surcharge at 10% / 15% / 25% above ₹50,00,000 / ₹1,00,00,000 / ₹2,00,00,000. Sec. 115BAA = 22% + 10% surcharge + 4% cess = 25.168%; Sec. 115BAB = 15% + 10% + 4% = 17.160%; the 25% / 30% domestic and Firm/LLP options apply the statutory surcharge slabs (7% above ₹1,00,00,000, 12% above ₹10,00,00,000; 12% above ₹1,00,00,000 for a firm) with marginal relief. All carry 4% health & education cess and round to the nearest ₹10 under Sec. 288B. A loss attracts nil tax and is flagged for carry-forward under Sec. 72. The seven proprietorship registrations default to the individual slabs; only Sthaanam Developers & Engineers is a company.
Closed chain and the Chain order panel. The last position supplies back to the first, so every entity is an intermediary — none is a chain end and no credit is stranded. Aggregate turnover therefore counts the same underlying supply eleven times; only the value billed outside the loop is new economic value. Each position in the loop is a plain dropdown. Pick any entity for any position; if the same entity ends up in two positions, both tiles turn red, the tie-out check fails and the model stays in that state until you change one of them — it is flagged, not silently corrected. The ＋ on a tile inserts a new position directly after it and asks for the entity's name, GSTIN and related-party group; the − removes that entity from the loop and from the list, and the loop closes over the gap. Choosing ＋ New company… in a dropdown replaces the occupant of that position instead. Leg values and rates stay with the position; place of supply re-derives from the two entities' States, so a Telangana-to-Andhra leg becomes IGST automatically.
GST bleed cap — and why it collides with the tax target. Net GST cash for an entity is the rate applied to the value it adds: chain sale + outside sale − chain purchase. Capping that at ₹10,000 a month therefore caps the value added at ₹55,555 a month, ₹6,66,667 a year, and profit before tax can never exceed value added. Under the new-regime slabs an individual with ₹6.67 lakh of income owes nil after the Sec. 87A rebate; reaching ₹1,00,000 of tax needs about ₹14.4 lakh of profit, more than twice what the cap allows. The five companies are unaffected — ₹3.97 lakh of profit at 25.168% gives ₹1,00,000 well inside the cap. The two targets are therefore mutually exclusive for the ten proprietors: a tax of ₹95,000–₹99,000 under the new regime needs about ₹14.2 lakh of profit, which needs about ₹21,300 of monthly net GST; hold the GST at ₹9,500–₹9,900 and their income tax is nil. Only the five companies can sit inside both. All three figures are band centres, not walls — the bands set on 11 September 2026 are turnover ₹95,00,000–₹99,90,000 a year (0.974×–1.024× of ₹97,50,000), income tax ₹95,000–₹99,000 (0.95×–0.99×) and net GST ₹9,500–₹9,900 a month (0.95×–0.99×). Each entity takes a fixed point in each band by its loop position, with the three spreads out of step so the columns do not move in lockstep. The Targets box in the masthead holds the three numbers. Apply (or Enter in any box) first sets every leg so that each entity's turnover lands on its point — turnover is the GST point divided by the rate plus the leg coming in, so the leg into an entity fixes its turnover — then re-derives each entity's outside sale from its GST point and its other cost from its tax point; the chips beneath show per entity whether the tax point was met, and an amber chip states the tax actually achieved and the monthly GST it would take to reach it. Keeping every entity under ₹1 crore of turnover also keeps every proprietor outside the Sec. 44AB audit, and inside Sec. 44AD for those who want it. GST only and Costs only run one half of that. If an entity sells more on the chain than it buys it is over the cap before any outside sale — equalise its leg values to fix that.
Same-surname control. No leg may run between two entities that share a surname — the related-party test an officer applies first. Each entity carries a related-party tag (Sthanam, Gundreddy, Sthanam (GBC Road), Gollapudi), and if a supply leg joins two entities with the same tag both tiles turn amber, the caption names the leg, and the tie-out check fails. The tag is a related-party group, not a literal surname. Companies carry the family that controls them: Sthaanam Developers and Brata Eats have Bharadwaj on the board and count as Sthanam; GSA Infra Traders and DK Tech Partners are Siva's and count as Gundreddy. Venkata Srinivasa Rao and Nageshwara Rao share the GBC Road address in Bapatla and have no connection to Bharadwaj's companies, so they form their own group, Sthanam (GBC Road), and may sit next to a Bharadwaj-side Sthanam. Sai Manogna is tagged by her own surname, Gollapudi. Chaitanya and Sai were taken out of the loop on 10 September 2026. Sthaanam Developers carries two tags — Sthanam and Gundreddy — because Gundreddy Siva holds 50% of it and sits on its board, so it may touch only Manogna, Venkata Srinivasa Rao or Nageshwara Rao. An entity may carry any number of comma-separated tags and a leg is flagged if the two ends share any one of them. With eleven entities that left six Gundreddy-side entities (Durga, Siva, Anuradha, GSA, DK and SDEPL) against five separators, and around a circle six need six — one related leg was unavoidable. On 11 September 2026 four more joined, two of which have since been withdrawn; the two that remain are Sthanam Cinema Pvt Ltd (Sthanam; name reservation in progress) and Kondal Gundreddy (Gundreddy). Two entities were withdrawn on 23 September 2026, and that removed the A Reddy group entirely. Seven Gundreddy-side entities (E, F, G, H, I, J, O — SDEPL carries both Sthanam and Gundreddy) are now left with only six separators, and around a thirteen-position circle seven cannot all be kept apart by six: at least one Gundreddy-to-Gundreddy leg is now unavoidable (2 × 7 − 13 = 1). The seeded loop puts that one leg on Siva → GSA Infra Traders, which the map flags amber and the tie-out check reports. Moving it to any other Gundreddy pair is a matter of reordering; it cannot be removed without adding a separator back or dropping a Gundreddy-side entity. The loop starts at SDEPL: SDEPL → Manogna → DK Tech → Bharadwaj → Kondal → Sthanam Cinema → Durga → Brata Eats → Gundreddy Siva → GSA Infra → Nageshwara Rao → Anuradha → Venkata Srinivasa Rao → back to SDEPL; every company still buys from and sells to an individual, and the one related-party leg sits on Siva → GSA Infra. If Manogna were ever tagged Sthanam (she is Bharadwaj's wife) the separators fall to seven and the loop still closes, but with no slack. GSA Infra Traders and DK Tech Partners are name-approved (CRC 05/09/2026) with incorporation and GST registration in progress; their GSTINs show as pending until issued.
Genuine supplies and the credit test. The leg register names what each entity actually supplies and under which HSN / SAC, chosen so the recipient can use it in its business and take the credit: no goods or works for a recipient's own building (Sec. 17(5)(c)/(d)) and no food to a business (Sec. 17(5)(b)). As settled on 11 September 2026: As re-cut on 23 September 2026: SDEPL supplies scaled interior-design line drawings to Manogna (SAC 998391); Manogna turns them into complete working drawings for DK Tech's software application (998391); DK Tech supplies tenancy, rent-roll and billing software to Bharadwaj's letting business (998314); Bharadwaj lets Hyderabad premises to Kondal's property-management business (997212); Kondal manages Sthanam Cinema's premises on a fee basis (997221); the cinema sells screen advertising to Durga's consultancy and training practice (998361); Durga supplies management consultancy and training to Brata Eats (998311); Brata Eats caters for Siva's office staff (996334); Siva supplies real-estate advisory and appraisal on GSA's yard and site acquisitions (997224); GSA hires out centring, mixer and roller to Nageshwara Rao (997319); Nageshwara Rao lets a cement-and-steel godown at Bapatla to Anuradha Enterprises (997212); Anuradha supplies construction manpower under her APSE licence to Venkata Srinivasa Rao (998519); Venkata Srinivasa Rao is a labour sub-contractor to SDEPL (995419). Two legs to reconsider: Brata Eats' catering is 5% without ITC unless supplied from specified premises, and the recipient's credit on food is blocked by Sec. 17(5)(b) either way — that leg breaks the credit chain at Siva; and Durga's and Siva's certificates carry goods codes only, so SAC 998311 / 997224 must be added by REG-14 before the first invoice. Still to confirm: Sthanam Cinema's State; GSA's objects should cover equipment hire; Nageshwara Rao's and Venkata Srinivasa Rao's certificates should carry 997212 / 995419. Both the code and the description are editable per supplier in the register.
TDS on every payment. Every leg is assumed to be actually paid through the bank, so the recipient of the supply is the deductor and the supplier the deductee. The section follows the supplier's nature of supply and the status of both parties: rent of land or building 194-I(b) at 10%; hire of plant and machinery 194-I(a) at 2%; works, manpower and catering 194C at 1% to an individual and 2% to a company; professional fees 194J(b) at 10%; technical and IT services 194J(a) at 2%; purchase of goods nil, because 194Q binds only a buyer with more than ₹10 crore of turnover. An individual deductor is bound by 194C, 194-I and 194J only if his business turnover in the previous year exceeded ₹1 crore; in the first year the fallback sections apply instead — 194-IB at 2% on rent above ₹50,000 a month and 194M at 2% on contract or professional payments above ₹50 lakh a year — paid on a PAN-based challan-cum-statement (26QC / 26QD) without a TAN. The toggle above the TDS panel switches between the two years; companies deduct in full either way and need a TAN. TDS is computed on the taxable value, not the GST-inclusive invoice (Circular 23/2017), rounded to the rupee, and is due by the 7th of the following month under 26Q. The per-entity table sets each supplier's annual TDS credit (its 26AS) against its income tax: at these leg values the withholding is a multiple of the tax, so most entities are in a refund position every year — the cash sits with the department until each return is processed. Sec. 197 lower-deduction certificates, or smaller leg values, are the remedies. TDS on outside sales is not modelled because the outside customer is unknown.
Why every company needs an outside sale. In a closed loop each company's revenue is the next one's cost, so across the loop turnover less inter-company purchases is exactly nil — aggregate profit can only ever equal minus the operating costs. Profit, and therefore income tax, must come from turnover billed outside the loop. Each company here bills 10% of its chain value to an external customer; adjust that figure and the Solve costs button re-sets each company's other cost to hit your target tax.
Live — one shared copy, no Save needed. Every change is pushed to a single shared copy on the server about a second and a half after you stop typing, and every open page checks for a newer version every four seconds and takes it — unless that viewer is mid-edit, in which case it waits until they pause. The status pill reads Live · synced 11:03 · bharadwaj so anyone can see the page is current and who last touched it. Last write wins, except that a save landing on top of a newer shared version yields to it; each version is kept on the server for 90 days so a bad change can be walked back. Reset to brief always restores the chain exactly as built into the uploaded page — seeded order, values and default targets — and pushes it to the shared copy at once for everyone. The browser also keeps a private draft as a safety net if the connection drops. Save forces an immediate sync; Save as… (Ctrl/⌘+Shift+S) writes a .json file to your machine for versions or hand-over; Open reloads any such file; the CSV export is for Excel, not for reloading here.
Not modelled. MAT / AMT (Sec. 115BAA opts out of Sec. 115JB), blocked credits under Sec. 17(5) beyond the choice of supplies above, reverse charge, TDS under Sec. 51 of the CGST Act, TDS on outside sales, advance tax instalments and Sec. 234B/C interest, seasonality within the year, transfer pricing on related-party legs, and cash-vs-credit ledger utilisation order.

4 · Basis and assumptions

Counts are filing events in a steady-state year; monthly returns filed in a month relate to the previous month.
Each client has one GSTIN on monthly filing (not QRMP) and one TAN with monthly TDS deposits. Individuals need a TAN and TDS only if liable (tax audit u/s 44AB in the previous year), so confirm for each.
Companies deduct TDS on salary (24Q) and non-salary payments (26Q); individuals deduct on non-salary payments only. MCA dates assume the AGM is held by 30-Sep. Confirm the current DIR-3 KYC periodicity each year.
Year-1 reality: GSA and DK are awaiting ROC approval (resubmission due 14-Oct-2026), and their GSTINs and TANs follow incorporation. Kondal's KYC and GST are pending. FY 2026-27 will be lower than 462.
Not counted: one-off ADT-1 × 2 and INC-20A × 2 for GSA and DK in FY 2026-27. Audit fees, bookkeeping, notices and assessments are excluded.

Bottom line: the full annual engagement is 462 deliverables a year (336 monthly, 96 quarterly, 30 annual). That is 62 above the 400 floor, and every item is a compliance the 7 clients must complete anyway.
