In Return Assembly

India Return Assembly Skill v0.1

General reference only. This skill is general tax/accounting reference material for AI-assisted workflows. It has not been reviewed for any specific person's facts, documents, elections, deadlines, residency, filing status, or local procedures. Do not rely on it to file, pay, amend, or take a tax position without review by a qualified professional in the relevant jurisdiction.

CRITICAL EXECUTION DIRECTIVE -- READ FIRST

When this skill is invoked, you have already passed through intake. The user has consented to the full workflow. Execute all steps without pausing for permission.

Specifically:

• Do NOT ask the user "how deep do you want me to go" or "do you want the full package" or any variant. The user asked for their tax returns. They want their tax returns. Produce them.
• Do NOT announce how many tokens or tool calls this will take. Execute.
• Do NOT ask which deliverables to prioritise. Produce all deliverables listed in Section 4. If you run out of context mid-execution, finish the computation work first (numbers, positions, flags) then produce whatever formatted outputs you can, and at the very end state clearly which deliverables were not produced and why.
• Do NOT re-validate scope that intake already validated. If in-freelance-intake produced an intake package, trust it. You can cross-check specific numbers during reconciliation but do not re-interrogate the user about residency, business structure, or anything else intake already captured.
• Do NOT pause between content skills to check in. Run them in dependency order (Section 2) without prose status updates between each one. A single status message at the end is fine.
• Self-checks are targets, not blockers. If a self-check fails, note it in the reviewer brief's open flags section and continue. Do NOT halt the entire workflow because one self-check had an ambiguous answer.
• Primary source citations go in the final reviewer brief, not in intermediate computation steps.

The user has already been told (by the intake skill) that the final package requires CA signoff before filing. State it once in the final output and move on.

Failure mode to avoid: The skill halts mid-execution and asks the user a meta-question about workflow pacing. If you feel the urge to ask "how should I proceed," the correct action is to pick the most defensible path and proceed, flagging the decision in the reviewer brief so the reviewer can challenge it.

What this file is

The final capstone skill for India self-employed returns. Every India content skill feeds into this one. The output is the complete reviewer package that a Chartered Accountant can review, sign off on, and deliver to the client along with filing instructions.

This skill coordinates execution of the content skills, verifies cross-skill consistency, and assembles the final deliverable.

Section 1 -- Scope

Produces the complete India filing package for:

• Full-year Indian residents
• Self-employed individuals and professionals (sole proprietors)
• Financial year 2025-26 (Assessment year 2026-27)
• Filing GST returns (GSTR-3B + GSTR-1 if registered), ITR-3 or ITR-4, advance tax reconciliation, TDS credit reconciliation

Section 2 -- Execution order and dependency chain

The skill enforces the following execution order:

1. india-gst -- GSTR-3B + GSTR-1 reconciliation (Q2 skill)

   • Runs first because GST turnover figures feed into the ITR
   • Reconcile GSTR-3B monthly/quarterly summaries with books
   • Verify GSTR-1 outward supply details match invoices
   • Reconcile ITC claimed with GSTR-2B auto-populated data
   • Output: GST turnover, output tax, ITC utilised, cash GST paid, reverse charge

2. in-income-tax -- ITR-3 or ITR-4 return (Q2 skill)

   • Depends on GST output: gross receipts must match GST turnover (ex-GST for regular taxpayer)
   • For ITR-4 (presumptive 44ADA): 50% deemed profit on gross receipts, no expense schedule
   • For ITR-3 (actual profit): full P&L with expense deductions, depreciation schedule, balance sheet
   • Output: total income, tax liability at applicable slab rates, regime comparison if requested

3. in-advance-tax -- Quarterly advance tax reconciliation (Q2 skill)

   • Depends on ITR: final tax liability determines whether advance tax was sufficient
   • Reconcile advance tax paid (from Form 26AS) against liability
   • Compute s.234B interest (default on advance tax shortfall -- if paid < 90% of assessed tax)
   • Compute s.234C interest (deferment -- quarterly shortfall in instalments: 15%/45%/75%/100%)
   • Output: advance tax schedule, shortfall computation, interest liability

4. in-tds-freelance -- TDS credit reconciliation (Q4 stub, flag)

   • Depends on ITR: TDS credits offset final tax liability
   • Reconcile Form 26AS TDS entries with income declared in ITR
   • Flag mismatches (TDS claimed but income not shown, or income shown but TDS not reflected)
   • Status check: in-tds-freelance is currently a Q4 stub. If the stub has substantive content, use it. If it is still a placeholder, compute TDS reconciliation using Form 26AS data from intake and flag in the reviewer brief that the dedicated skill was not available.
   • Output: TDS credit summary, mismatches, Form 26AS vs ITR reconciliation

If any upstream content skill fails to produce validated output, the assembly skill notes the failure in the reviewer brief and continues with available data rather than halting entirely.

Section 3 -- Cross-skill reconciliation

Cross-check 1: GST turnover matches ITR gross receipts

If mismatch: Flag for reviewer. Common causes: timing differences (invoice vs receipt basis), RCM supplies, credit notes, advances received but service not rendered.

Cross-check 2: If 44ADA presumptive -- 50% deemed profit, no further expense deduction allowed

If violation: If the computation claims actual expenses AND declares 50% deemed profit, check fails. It is one or the other.

Cross-check 3: Advance tax paid + TDS credits against final tax liability

If advance tax + TDS < 90% of assessed tax: s.234B interest applies at 1% per month (simple) from April of AY to date of filing or date of assessment.

If quarterly advance tax instalments fell short: s.234C interest applies at 1% per month for 3 months per shortfall quarter.

For 44ADA presumptive: entire advance tax can be paid by 15 March (single instalment). s.234C does not apply if 100% paid by 15 March.

Cross-check 4: Form 26AS TDS vs ITR income declaration

If mismatch: Common causes: deductor filed TDS return late, wrong PAN quoted, income accounted in different FY. Flag for reviewer with specific entries.

Section 5 -- Refusals

R-IN-1 -- Upstream skill did not run. Name the specific skill. Note: this is a warning, not a hard stop. Continue with available data and flag the gap.

R-IN-2 -- Upstream self-check failed. Name the specific check and note it in the reviewer brief. Continue.

R-IN-3 -- Cross-skill reconciliation failed. Name the specific reconciliation and describe the discrepancy. Flag for reviewer but continue.

R-IN-4 -- Intake incomplete. Specific missing intake items prevent computation. List what is missing and ask the user for the specific data point.

R-IN-5 -- Out-of-scope item discovered during assembly. E.g., capital gains requiring Schedule CG, rental income requiring Schedule HP, foreign assets requiring Schedule FA, or partnership income. Flag and exclude from computation.

Section 6 -- Self-checks

Check IN-A1 -- All upstream skills executed. india-gst, in-income-tax, in-advance-tax all produced output. in-tds-freelance produced output or was computed from Form 26AS data.

Check IN-A2 -- GST turnover matches ITR gross receipts. Within INR 100 tolerance.

Check IN-A3 -- If 44ADA: 50% deemed profit, no expense deductions claimed. Deemed profit = exactly 50% of gross receipts (or higher if voluntarily declared higher).

Check IN-A4 -- Advance tax + TDS reconciled against final liability. Total credits (advance tax + TDS + self-assessment tax) match the payment/refund position.

Check IN-A5 -- s.234B interest computed correctly. If advance tax paid < 90% of assessed tax, 1% simple interest per month from April AY to date of payment/assessment.

Check IN-A6 -- s.234C interest computed correctly. Quarterly shortfall interest at 1% for 3 months per deficient quarter.

Check IN-A7 -- Form 26AS TDS matches ITR. Every TDS entry in 26AS has corresponding income in ITR. Credits claimed match 26AS amounts.

Check IN-A8 -- Tax regime correctly applied. New regime: s.115BAC rates, no Ch VI-A deductions (except NPS 80CCD(2)). Old regime: regular slab rates, all deductions claimed.

Check IN-A9 -- s.87A rebate applied if eligible. New regime: if total income <= INR 12,00,000 (after standard deduction), rebate up to INR 25,000.

Check IN-A10 -- Surcharge and cess correctly computed. Surcharge applicable if total income > INR 50 lakh (10%/15%/25% tiers). Cess = 4% on tax + surcharge.

Check IN-A11 -- Filing calendar is complete. All deadlines for ITR, GST, advance tax, and TDS are listed with specific dates and amounts.

Check IN-A12 -- Reviewer brief contains legislation citations. Every position taken references the specific section of the Income-tax Act 1961, CGST Act 2017, or relevant rule.

Section 7 -- Output files

The final output is three files:

1. [client_slug]_2025-26_india_master.xlsx -- Single master workbook containing every worksheet and computation. Sheets include: Cover, GST Reconciliation (GSTR-3B vs books), ITR Computation (ITR-3 or ITR-4), Depreciation Schedule (if ITR-3), Advance Tax Reconciliation, TDS Credit Reconciliation, s.234B/234C Interest, Cross-Check Summary. Use live formulas where possible -- e.g., ITR gross receipts cell references the GST turnover cell; advance tax shortfall references the ITR final liability. Verify no #REF! errors. Verify computed values match within INR 1 before shipping.

2. reviewer_brief.md -- Single markdown file covering all sections from Section 4 above: executive summary, GST returns, ITR, advance tax, TDS, cross-skill reconciliation, flags, positions, planning notes.

3. client_action_list.md -- Single markdown file with step-by-step actions: immediate filings and payments, advance tax quarterly calendar for FY 2026-27, GST filing calendar, ongoing compliance reminders.

If execution runs out of context mid-build: produce whatever is complete, then state at the end which of the three files were not produced or are partial.

All files are placed in /mnt/user-data/outputs/ and presented to the user via the present_files tool at the end.

Section 8 -- Cross-skill references

Inputs:

• in-freelance-intake -- structured intake package (JSON)
• india-gst -- GSTR-3B/GSTR-1 reconciliation output
• in-income-tax -- ITR-3/ITR-4 computation output
• in-advance-tax -- Advance tax reconciliation and interest output
• in-tds-freelance -- TDS credit reconciliation output (or fallback computation from Form 26AS)

Outputs: The final reviewer package. No downstream skill.

Section 9 -- Known gaps

1. PDF form filling is not automated. The reviewer uses the worksheets to fill official ITR forms on incometax.gov.in.
2. E-filing is handled by the reviewer via the income tax portal, not by this skill.
3. Payment execution is the client's responsibility; the skill only provides instructions and amounts.
4. Tax audit (Form 3CB-3CD) preparation is not automated -- if audit is required, the skill flags it and the CA prepares the audit report separately.
5. in-tds-freelance is a Q4 stub. Until it is fleshed out, TDS reconciliation is computed using Form 26AS data from intake. This is a redundancy, not a gap -- the data source (Form 26AS) is the same.
6. Multi-year depreciation tracking assumes the prior year schedule is provided. If not, only current-year acquisitions are depreciated.
7. Capital gains computation (Schedule CG) is out of scope.
8. Foreign assets reporting (Schedule FA) is out of scope.
9. Rental income (Schedule HP) is out of scope beyond noting it as other income.
10. The package is complete only for FY 2025-26; FY 2026-27 appears only as prospective planning.
11. State-level professional tax varies by state and is treated as a known deduction from intake, not independently computed.
