Indonesia Return Assembly Skill v1.0

CRITICAL EXECUTION DIRECTIVE — READ FIRST

When this skill is invoked, the user has already passed through intake and the relevant content skills. They want their finished SPT working paper. Execute all steps without pausing for permission.

Specifically:

• Do NOT ask "do you want me to assemble the full package". The user asked for the return. Produce it.
• Do NOT re-interrogate the user about residency, NPWP, or business structure — intake already captured this; trust the upstream packages.
• Do NOT pause between reconciliation steps to check in. Run all cross-checks in sequence; flag failures in the reviewer brief and continue.
• Self-checks are targets, not blockers. If a check fails, note it under "Reviewer Attention Flags" and continue.
• Do NOT submit anything to Coretax. This skill produces a working paper plus filing instructions. A qualified Indonesian tax consultant (Konsultan Pajak bersertifikat) must review and the taxpayer (or authorised filer) submits via Coretax.

If you feel the urge to ask "how should I proceed", pick the most defensible path, proceed, and flag the decision for the reviewer.

What this file is

The final capstone skill for Indonesian annual tax returns. It consumes the outputs of every other Indonesia skill and assembles a single unified working paper covering either:

• SPT 1770 / 1770S / 1770SS — annual return for resident individuals (Orang Pribadi), including sole proprietors operating under UMKM PPh Final (PP 55/2022) or the progressive regime
• SPT 1771 — annual return for resident corporates (Badan), including PT, CV, and Koperasi

The output is a reviewer-ready package: line-by-line SPT working paper, cross-skill reconciliation table, payment instructions (kode billing for Coretax), filing instructions, reviewer checklist, and taxpayer action list.

Section 2 — Required inputs from upstream skills

The assembly skill does not recompute anything. It expects structured outputs from the following upstream skills. If an upstream skill did not run, the assembly notes the gap and continues with available data.

2.1 Individual return (SPT 1770) — inputs

Upstream skill	Output consumed	Where it lands on the SPT
id-bookkeeping	General ledger trial balance; income/expense detail	Source for Lampiran I (business income)
id-income-tax	Progressive PPh OP computation: PKP, PPh terutang, PTKP applied	Form 1770 Induk Part B & C
id-pph-final-umkm	UMKM Final 0.5% computation; monthly SSP records; cumulative gross turnover; verification turnover is ≤ IDR 4.8 billion	Lampiran III-A (PPh Final & Bersifat Final)
id-payroll-pph21	Employment income from Bukti Potong 1721-A1; PPh 21 already withheld	Form 1770 Induk Part A; Lampiran I Bagian B
indonesia-vat	If individual is PKP: VAT input/output position; nothing flows to PPh return but reviewer checks consistency of revenue figures	Cross-check only, not a line on 1770
id-withholding	Bukti Potong PPh 22 / 23 / 4(2) received as a recipient; PPh 22 / 23 / 4(2) paid as a withholder	Lampiran I & III (credits); separate SPT Masa for amounts withheld

2.2 Corporate return (SPT 1771) — inputs

Upstream skill	Output consumed	Where it lands on the SPT
id-bookkeeping	Full audited or management financial statements: Neraca (balance sheet), Laporan Laba Rugi (P&L)	Lampiran V (financial statements); Lampiran I (fiscal reconciliation)
id-corporate-tax	Fiscal profit (laba fiskal); PPh Badan computation at 22% (or facility-eligible rates per UU HPP); deferred tax	Form 1771 Induk Part B & C
id-pph-final-umkm	If entity qualifies for PP 55/2022 0.5% Final regime and is within the 3-year UMKM Badan window (PT) or 4-year window (CV/Firma/Koperasi)	Lampiran IV (PPh Final & Bersifat Final)
id-payroll-pph21	Employee payroll cost classification; PPh 21 employer obligations reconciled	Lampiran II (cost of employment)
indonesia-vat	If PKP: VAT input/output reconciled; PPN paid is not deductible for PPh; cross-check revenue figures match	Cross-check; PPN Masukan that becomes a cost flows to fiscal P&L
id-withholding	PPh 22/23/4(2)/15/26 withheld by counterparties (credits on 1771); withholding made by entity on suppliers (SPT Masa obligations)	Lampiran III (kredit pajak); separate SPT Masa monthly

2.3 Intake-required identifiers

Identifier	Required for
NPWP (Nomor Pokok Wajib Pajak) — 16-digit (post-Coretax merge with NIK for individuals)	All returns
NITKU (Nomor Identitas Tempat Kegiatan Usaha) — branch/location identifier introduced under Coretax	All returns post-PMK 81/2024
KLU (Klasifikasi Lapangan Usaha) — business classification code	Determines JKK class, applicability of UMKM regime
KPP code (Kantor Pelayanan Pajak / tax office)	Filing location, kode billing routing
Marital status & dependents (for individuals)	PTKP determination

If any identifier is missing, the assembly skill flags it as "Needs Input" and produces the working paper with placeholders rather than halting.

---

Section 3 — Tax computation reconciliation

The assembly skill verifies that numbers from the upstream skills are mutually consistent. If a cross-check fails by more than IDR 1,000, the discrepancy is raised in the reviewer brief — never silently rounded.

Cross-check 1 — Revenue reconciliation (turnover ties across skills)

Source	Figure	Rule
id-bookkeeping P&L gross revenue	Total operating revenue	Anchor figure
indonesia-vat annual DPP (Dasar Pengenaan Pajak) on output VAT	Sum of monthly SPT Masa PPN Faktur Pajak Keluaran	Must reconcile to bookkeeping revenue ± permitted timing differences
id-pph-final-umkm cumulative gross turnover	Sum of monthly UMKM gross	Must equal bookkeeping revenue for the UMKM-eligible portion
id-income-tax or id-corporate-tax gross income	Top line of fiscal P&L	Must equal bookkeeping ± fiscal-vs-commercial adjustments (Lampiran I)

If mismatch: Likely causes are (i) VAT-exempt revenue (PPN dibebaskan) not in VAT output, (ii) accrual vs cash timing differences, (iii) intra-group eliminations, (iv) revenue that is itself PPh Final at source (rental, construction).

Cross-check 2 — PPh credits add up correctly

For individuals (SPT 1770):

Line	Source skill	Description
PPh 21 withheld by employer(s)	id-payroll-pph21 (Bukti Potong 1721-A1)	Credit
PPh 22 withheld at import / state purchase	id-withholding	Credit
PPh 23 withheld on services / royalties / dividends	id-withholding	Credit
PPh 24 — foreign tax credit	id-income-tax (if applicable)	Credit, capped
PPh 25 — monthly installments paid during the year	id-income-tax	Credit
PPh Final paid (UMKM 0.5%, rental, etc.)	id-pph-final-umkm	NOT a credit against progressive PPh — separate column

For corporates (SPT 1771): same list except no PPh 21 employment credit (employer does not personally claim PPh 21 against PPh Badan).

Rule: Total credits cannot exceed PPh terutang (tax liable) for refund purposes unless the excess is properly recognised in Lampiran III with supporting Bukti Potong.

Cross-check 3 — PPh Final UMKM matches monthly SSPs (Surat Setoran Pajak)

Item	Source	Rule
Sum of monthly UMKM 0.5% paid via SSP	id-pph-final-umkm monthly log	Must equal 0.5% × cumulative gross turnover for UMKM-eligible months
Coretax billing receipts (NTPN — Nomor Transaksi Penerimaan Negara)	Bank statements / Coretax history	Each monthly payment must have an NTPN
Threshold guard: cumulative turnover ≤ IDR 4.8 billion for the year	id-pph-final-umkm	If exceeded mid-year, switch to progressive PPh from the month following the breach

If mismatch: Investigate missing months (UMKM is monthly, due 15th of the following month under PMK 164/2023), incorrect NTPN, or threshold breach not actioned.

Cross-check 4 — PPh 21 reconciliation between annual and monthly returns

Item	Source	Rule
Sum of monthly SPT Masa PPh 21 filed (Jan–Nov via TER)	id-payroll-pph21	Should match total TER withholding for the year
December true-up (annual recalculation under PP 58/2023)	id-payroll-pph21	Reconciled to annual PPh 21 terutang
Total PPh 21 borne by entity	id-payroll-pph21 employer cost	Cross-checked to Form 1721 A1 (employer's annual PPh 21 return), due 31 March 2026

If mismatch: Likely cause is mid-year joiners/leavers, bonus or THR not included in the correct month's TER, or December true-up not booked.

Cross-check 5 — Withholding compliance as a withholding agent

If the taxpayer (especially a Badan) is required to withhold PPh on its suppliers:

Item	Source	Rule
PPh 23 withheld on services and royalties paid	id-withholding	Sum of monthly SPT Masa PPh 23/26
PPh 4(2) withheld on rent, construction, prizes	id-withholding	Sum of monthly SPT Masa PPh 4(2)
PPh 21/26 withheld on consultants and non-employees	id-payroll-pph21 + id-withholding	Sum of monthly SPT Masa PPh 21/26
Bukti Potong issued to counterparties	id-withholding e-Bupot Unifikasi	Should match the SPT Masa filings

Rule: Withholding is the entity's obligation, not its own tax credit. Failure to withhold is corrected with Surat Setoran Pajak plus 2% per month interest (UU HPP). Flag any apparent failure for the reviewer.

Cross-check 6 — VAT-to-PPh consistency (for PKP)

Item	Source	Rule
PPN Masukan that was creditable	indonesia-vat	NOT a cost in fiscal P&L
PPN Masukan that was non-creditable (per Pasal 9(8) UU PPN)	indonesia-vat	IS a cost in fiscal P&L
PPN on capital goods	indonesia-vat	Either credited (PKP) or capitalised into asset cost (non-PKP)

If inconsistency: An expense net of PPN in the P&L while the PPN was also not claimed on the VAT return means the PPN is lost. Flag for reviewer.

Cross-check 7 — Tolerance discipline

For every cross-check above, the threshold is IDR 1,000. If a difference is between IDR 1,000 and IDR 100,000, document the variance and proceed with a reviewer flag. If above IDR 100,000, raise as "Needs Input" — the reviewer should resolve before sign-off.

Section 4 — Working paper template: individual SPT 1770

The working paper is built around the structure of Form 1770 (the full form for individuals with business or multiple income sources). Form 1770S applies to individuals with single-employer income above IDR 60 million but no business income; Form 1770SS applies to single-employer income ≤ IDR 60 million. The assembly skill picks the correct form based on intake.

4.1 Induk Form 1770 — line-by-line

Bagian (Part)	Line	Description	Source
Identitas	NPWP, NIK, NITKU, name, KLU, address, marital status	All	Intake
A. Penghasilan Neto	1	Net income from business (usaha) — progressive regime	id-income-tax
	2	Net income from independent profession (pekerjaan bebas)	id-income-tax
	3	Net income from employment	id-payroll-pph21 (sum of Bukti Potong 1721-A1)
	4	Net income from other sources (dalam negeri lainnya)	id-bookkeeping (interest, royalties, sewa non-final)
	5	Net foreign income (luar negeri)	id-income-tax (if applicable)
	6	Total penghasilan neto	Sum 1–5
B. Penghasilan Tidak Kena Pajak (PTKP)	7	PTKP based on K/0, K/1, …, TK/0, etc.	id-payroll-pph21 PTKP table
C. Penghasilan Kena Pajak (PKP)	8	Line 6 − Line 7	Computed
D. PPh Terutang	9	Apply progressive brackets to Line 8	id-income-tax
E. Kredit Pajak	10	PPh 21 withheld	id-payroll-pph21
	11	PPh 22 / 23 / 24 / 25	id-withholding + id-income-tax (PPh 25)
	12	Total credits	Sum
F. PPh Kurang/Lebih Bayar	13	Line 9 − Line 12 (positive = balance due; negative = refund / kompensasi)	Computed
G. Angsuran PPh 25 tahun berikutnya	14	Monthly installment for 2026 = PPh terutang ÷ 12 (subject to adjustments per PMK 215/2018)	id-income-tax

4.2 Lampiran (Schedules) checklist

Lampiran	Title	When used
Lampiran I	Penghasilan Neto Dalam Negeri Lainnya & Penghasilan Neto Luar Negeri	If non-employment, non-business income exists
Lampiran II	Daftar Pemotongan / Pemungutan PPh oleh Pihak Lain dan PPh Yang Ditanggung Pemerintah	List every Bukti Potong received
Lampiran III	Penghasilan yang Dikenakan PPh Final dan/atau Bersifat Final	UMKM 0.5%, deposito interest 20%, dividend 10%, rental 10%, etc.
Lampiran IV	Harta pada Akhir Tahun & Kewajiban / Utang pada Akhir Tahun	Net worth disclosure (mandatory)
Lampiran V	Daftar Susunan Anggota Keluarga	Family members for PTKP support

4.3 UMKM PPh Final treatment on 1770

If the taxpayer used PP 55/2022 UMKM 0.5% during 2025:

• Business gross turnover that was UMKM-final goes to Lampiran III, NOT Part A line 1
• PPh Final UMKM paid via monthly SSP is reported on Lampiran III; it is not a credit against progressive PPh — it is a separate final settlement
• If the IDR 4.8 billion cumulative threshold was breached mid-year, the months after the breach revert to progressive regime; the working paper must split the year cleanly

Lampiran khusus	Transfer pricing documentation summary (Lampiran 3A / 3B)	If related-party transactions exceed thresholds in PMK 213/2016

5.3 UMKM PPh Final treatment on 1771

If the entity used PP 55/2022 UMKM 0.5% during 2025:

• The UMKM window is time-limited: 3 years for PT, 4 years for CV/Firma/Koperasi, 7 years for individuals (Orang Pribadi) measured from the start year of UMKM utilisation (PP 55/2022 Pasal 59)
• Revenue under UMKM goes to Lampiran IV (PPh Final), not the main PKP computation
• The reviewer must confirm the entity is within its UMKM window. If 2025 is the final eligible year, this must be flagged so 2026 planning reflects the switch to standard 22% regime

---

Section 6 — Payment instructions: kode billing & SSP via Coretax

Under PMK 81/2024 (Coretax implementation), all PPh payments are settled by generating a kode billing (15-digit billing code) in Coretax DJP, then paying via bank channel (teller, ATM, internet banking, m-banking) or authorised payment processor. The successful payment generates an NTPN (Nomor Transaksi Penerimaan Negara) which is the proof of payment.

6.1 Kode Akun Pajak (MAP) — common codes

TBC — verify current MAP code in Coretax before generating the billing. The list below is the conventional set; Coretax may have introduced new MAP codes since 1 January 2025 transition. Always confirm against the Coretax dropdown at billing time.

MAP code	Description	Used for
411125	PPh Pasal 25/29 Orang Pribadi	Individual annual settlement (Line 13 on 1770) + monthly PPh 25
411126	PPh Pasal 25/29 Badan	Corporate annual settlement (Line 9 on 1771) + monthly PPh 25
411128	PPh Final	UMKM 0.5% (PP 55/2022); rental 10%; deposit interest 20%; etc. — Kode Jenis Setoran (KJS) sub-code disambiguates
411121	PPh Pasal 21	Monthly employment withholding
411124	PPh Pasal 23	Monthly withholding on services, royalties, etc.
411127	PPh Pasal 26	Withholding on non-residents
411122	PPh Pasal 22	Import / state purchases / pertamina
411211	PPN Dalam Negeri	Monthly PPN settlement
411221	PPN Impor	Import VAT

6.2 KJS (Kode Jenis Setoran) — sub-code

For each MAP code, a KJS specifies the nature of the payment (e.g., MAP 411125 with KJS 200 = "Tahunan" / annual; KJS 100 = "Masa" / monthly). The reviewer must confirm the correct KJS pairing. Coretax surfaces only the valid combinations once the MAP is selected.

6.3 Billing-to-payment flow

1. Log into Coretax DJP with NPWP + password (or DJP-issued certificate for businesses)
2. Navigate to "Pembuatan Kode Billing" (Generate Billing Code)
3. Select Jenis Pajak (MAP), KJS, Masa Pajak (tax period), and amount
4. Generate billing — receives 15-digit ID-Billing valid for 30 days
5. Pay via authorised channel (bank transfer / Virtual Account / Tokopedia / Bukalapak / Pos Indonesia / etc.)
6. Receive NTPN (printable / downloadable in Coretax) — this is the legal proof of payment
7. NTPN auto-feeds into Coretax taxpayer ledger; appears as a credit on the relevant SPT

6.4 Payment timing relative to filing

Payment	Due date	Filing reference
PPh kurang bayar — Individuals (1770)	Before filing the SPT 1770 and no later than 31 March 2026	Line 13 on 1770
PPh kurang bayar — Corporates (1771)	Before filing the SPT 1771 and no later than 30 April 2026	Line 9 on 1771
Monthly PPh 21 (December 2025)	10 January 2026 (PMK 81/2024 Article 60)	SPT Masa PPh 21 December
Monthly PPh 25 (December 2025)	15 January 2026	Monthly installment
Monthly UMKM Final (December 2025)	15 January 2026	SSP via Coretax
Monthly PPN (December 2025)	End of January 2026	SPT Masa PPN December

Rule: The NTPN must exist before SPT submission, otherwise the credit cannot be claimed on the return.

8. File Form 1721 A1 (annual PPh 21 employer return) — deadline 31 March 2026

## Monthly compliance through 2026

| Item | MAP | Due |
|---|---|---|
| PPh 21 (monthly) | 411121 | 10th of following month |
| PPh 25 (monthly installment) | 411125/126 KJS 100 | 15th of following month |
| UMKM Final 0.5% (if applicable) | 411128 | 15th of following month |
| PPh 23 / 4(2) withheld | 411124 / 411128 | 10th of following month |
| SPT Masa PPN (if PKP) | 411211 | End of following month |

## Record retention

Per UU KUP Pasal 28 ayat 11, accounting records must be retained for **10 years** in Indonesia. This includes:
- General ledger and supporting documents
- Bukti Potong issued and received
- Faktur Pajak (PPN invoices)
- SSP / NTPN receipts
- BPE filing receipts

Records must be kept in Indonesia (Pasal 28 ayat 11) — offshore storage requires DJP approval.

Section 10 — 2026 planning notes

The capstone produces a forward-looking section so the taxpayer arrives at next year's filing with no surprises.

10.1 Monthly PPh 25 for 2026

Computed in the upstream skill (id-income-tax or id-corporate-tax). Rule:

• Individuals (PMK 215/PMK.03/2018): PPh 25 monthly = (PPh terutang 2025 − all kredit pajak 2025) ÷ 12, paid by the 15th of each month from January 2026 via MAP 411125 KJS 100
• Corporates: Same formula; MAP 411126 KJS 100
• New businesses / first year of progressive regime: PPh 25 = 0 for the months before the first full assessment year; first installment is the month after registration / breach of UMKM threshold

10.2 UMKM regime planning

If the taxpayer is using UMKM 0.5% in 2025:

• Check the UMKM window remaining (3y for PT / 4y for CV / 7y for Orang Pribadi from start year under PP 55/2022)
• If 2025 is the final year, 2026 reverts to:
  • Individual: Progressive PPh OP with bookkeeping (pembukuan) — switch from norma penghitungan if applicable
  • Corporate: Standard PPh Badan 22% (or Article 31E facility for SME)
• Even if window is not closing, monitor cumulative gross turnover. If 2026 turnover is expected to exceed IDR 4.8B, plan the regime switch and PKP-VAT registration

10.3 VAT planning

• PKP registration threshold: cumulative gross turnover IDR 4.8 billion in a year (PMK 197/PMK.03/2013)
• If approaching threshold during 2026, register as PKP before crossing — issue Faktur Pajak from registration date

10.4 Coretax compliance updates

PMK 81/2024 introduced Coretax DJP as the single integrated tax system. Reviewers should monitor DJP circulars (Surat Edaran Direktur Jenderal Pajak) through 2026 for transitional easements, form revisions, and new MAP / KJS combinations. TBC — confirm the active list at filing time.

10.5 Transfer pricing planning

For corporates with related-party transactions (under PMK 213/PMK.03/2016 thresholds):

• Local file & master file due by SPT 1771 filing deadline (30 April 2026)
• CbCR (Country-by-Country Reporting) for groups with consolidated revenue ≥ IDR 11 trillion — 12 months after fiscal year-end
• Flag if 2025 related-party gross transactions exceeded IDR 50 billion or any single counterparty exceeded IDR 5 billion

Section 11 — Conservative defaults

When inputs from upstream skills are ambiguous or missing, apply the following defaults and flag for the reviewer:

Situation	Conservative default
Cross-skill reconciliation differs by > IDR 1,000	Flag as "Needs Input"; do not silently round
MAP / KJS code uncertain for a payment	Use "TBC — verify current MAP code in Coretax" and DO NOT generate billing
UMKM window status unclear	Treat as final year; default 2026 to progressive regime
KLU code missing	Flag; use 70209 (General consulting) as placeholder for individuals; 64200 (Holding) for badan — note it must be corrected before filing
NITKU missing post-Coretax	Flag; cannot submit without it
Bukti Potong missing for a claimed credit	Exclude the credit; flag for taxpayer to obtain the Bukti Potong
Audit requirement unclear (Badan revenue near threshold)	Recommend audit (UU PT thresholds: revenue ≥ IDR 50B or assets ≥ IDR 50B)
December PPh 21 true-up not yet booked	Treat year as incomplete; cannot finalise SPT until December payroll closed
Foreign income with no certificate of residency	Disallow PPh 24 credit; flag for documentation
Related-party transactions undocumented	Flag transfer pricing risk; do not silently assume arm's-length
Payment due but no NTPN	Mark SPT credit as "pending payment"; advise taxpayer to settle before filing

Tolerance rule (repeated for emphasis): IDR 1,000 reconciliation tolerance. Any larger discrepancy is escalated, not absorbed.

Section 12 — Refusals

R-ID-ASM-1 — Upstream skill did not run. Name the missing skill. Continue with available data; flag the gap; do not fabricate the missing computation.

R-ID-ASM-2 — Upstream self-check failed. Note the specific check; continue but flag.

R-ID-ASM-3 — Cross-skill reconciliation > IDR 1,000. Raise as "Needs Input"; do not silently round.

R-ID-ASM-4 — Out of scope: VAT margin scheme, oil & gas / mining special regimes, branch profit tax (BPT) under PPh 26(4) for permanent establishments, controlled foreign company (CFC) rules under PMK 93/2019, tax holidays under PP 78/2019, special economic zone (KEK) facilities. Flag for human specialist; do not attempt.

R-ID-ASM-5 — Out of scope: non-resident individuals, mixed-residency years, expatriate package taxation under PMK 18/2021. Refer to a specialist; this skill assumes full-year Indonesian tax residency.

R-ID-ASM-6 — Intake incomplete. Name the missing intake field (NPWP, NITKU, KLU, marital status, dependents). Cannot finalise the SPT until provided.

R-ID-ASM-7 — Asked to submit to Coretax. This skill produces a working paper. Submission is the taxpayer's (or their authorised filer's) action, after Konsultan Pajak review and sign-off. Decline politely; provide the filing instructions instead.

Section 13 — Self-checks

Check ID-ASM-1 — All upstream skills required for the chosen form have produced output, or the gap is flagged.

Check ID-ASM-2 — Revenue reconciles between id-bookkeeping, indonesia-vat, and the chosen PPh skill within IDR 1,000.

Check ID-ASM-3 — PPh credits sum correctly across PPh 21/22/23/24/25/26, with each credit backed by a Bukti Potong + NTPN.

Check ID-ASM-4 — UMKM monthly SSPs (if applicable) sum to 0.5% of cumulative UMKM-eligible turnover; each month has an NTPN.

Check ID-ASM-5 — PPh 21 annual employer return (1721 A1) ties to sum of monthly TER plus December true-up.

Check ID-ASM-6 — For corporates: fiscal reconciliation (Lampiran I-1771) ties commercial profit to fiscal profit; loss carryforward used does not exceed 5-year limit (UU PPh Pasal 6).

Check ID-ASM-7 — UMKM window status is verified and 2026 regime is named.

Check ID-ASM-8 — All MAP / KJS codes used in the kode billing instructions are flagged "TBC — verify in Coretax" if not directly confirmed against current PMK 81/2024 annexes.

Check ID-ASM-9 — Filing deadline (31 March or 30 April 2026) is explicitly stated in the action list with the correct date.

Check ID-ASM-10 — Record retention period (10 years per UU KUP Pasal 28) is stated.

Check ID-ASM-11 — Reviewer brief contains legislation citations for every position taken (UU KUP, UU PPh, UU HPP, UU PPN, relevant PP / PMK).

Check ID-ASM-12 — BPE (Bukti Penerimaan Elektronik) retention is included in the action list.

Check ID-ASM-13 — Konsultan Pajak sign-off requirement is stated in the executive summary and action list.

Section 14 — Output files

The final output is three files:

1. [taxpayer_slug]_2025_id_master.xlsx — Master workbook. Sheets: Cover, Identitas, 1770 Induk (or 1771 Induk), Lampiran I-V (or I-VI for corporate), UMKM Final Tracker, Bukti Potong Register, NTPN Register, Cross-Check Summary, Kode Billing Schedule. Use live formulas where possible; verify no #REF! errors.

2. reviewer_brief.md — Markdown file with all Section 8 contents.

3. taxpayer_action_list.md — Markdown file with all Section 9 contents.

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

If execution runs out of context mid-build, complete the computation work first and produce whichever formatted outputs are finished, then state clearly which deliverables are partial.

---

Section 15 — Known gaps

1. PDF form filling is not automated; the reviewer or taxpayer enters values into Coretax using the working paper.
2. Coretax XML generation is not produced by this skill; integrations with ERP / third-party software handle that.
3. Audit report attachment is the taxpayer's responsibility; this skill only flags when audit is required.
4. Transfer pricing local file / master file content is referenced but not assembled here (separate skill needed).
5. PPh 26 (non-resident withholding) computations are not part of UMKM and are referenced via id-withholding only.
6. Tax holidays, KEK, and special facility regimes (PP 78/2019, PMK 130/2020, etc.) are out of scope.
7. CbCR XML is not assembled here.
8. Coretax MAP / KJS combinations are subject to change in 2025–2026 transition; every code in this skill should be verified against the live Coretax dropdown.

Change log

• v1.0 (May 2026): Initial release. Modelled on mt-return-assembly and us-ca-return-assembly, adapted for Indonesian SPT 1770 / 1771, Coretax DJP filing, and PMK 81/2024 transition. Coordinates seven upstream Indonesia skills.
