Nigeria — Freelance / SME Intake — Skill v1.0

What this file is

The intake orchestrator for Nigerian-resident self-employed individuals, sole proprietors (Business Name / BN registered with the Corporate Affairs Commission), and small / medium private limited company (RC) founders. Every downstream Nigerian content skill depends on this skill producing a structured intake package first.

Job: (1) confirm taxpayer is in scope, (2) classify the regime (PIT for sole/BN vs CIT 0% small-co vs CIT 20% medium vs CIT 30% large), (3) decide whether the period falls under pre-NTA-2025 rules (CITA / PITA / FA 2019–2023) or under the Nigeria Tax Act 2025 (NTA 2025) effective 1 January 2026, (4) identify downstream skills to run, (5) hand off to ng-return-assembly. Outputs addressed to a credentialed Nigerian reviewer (ICAN or ANAN Chartered Accountant, CITN-registered tax practitioner, or legal practitioner where applicable). The reviewer signs off — this skill is not the preparer of record.

Section 1 — Quick reference: regime decision tree at a glance

Nigerian tax resident? -> NO = REFUSE (route to non-resident flow)
       |
Entity?
  +-- Sole trader / BN (no separate legal entity)
  |       -> Personal Income Tax Act (PITA) progressive rates 7-24%
  |          File with State Internal Revenue Service (LIRS / FCT-IRS / SIRS)
  |          Regime: ng-personal-income-tax (always); ng-statutory-deductions (NHF/NHIA/Pension if voluntary)
  |
  +-- Private limited company (RC, "Ltd")
          -> Companies Income Tax Act (CITA) until 31 Dec 2025
             Nigeria Tax Act 2025 (NTA 2025) from 1 Jan 2026
             |
             Turnover band (current FY):
               +-- ≤ N100m AND fixed assets ≤ N250m  (NTA 2025 "small company")
               |     -> CIT 0% (NTA 2025 s.56)  [pre-2026 threshold = N25m under FA 2019]
               |
               +-- N100m – N1bn  (NTA 2025 "medium company")
               |     -> CIT 20%
               |
               +-- > N1bn  (NTA 2025 "large company")
                     -> CIT 30% + 4% Development Levy (NTA 2025)

Parallel routing (independent of regime):

• Taxable turnover ≥ N25m trailing-12 → VAT registration mandatory (FA 2019 s.46; NTA 2025 carries this forward) → route ng-vat.
• Employees on payroll → route ng-paye + ng-statutory-deductions + ng-payroll.
• Pays Nigerian or foreign suppliers / contractors / rent / royalties → route ng-wht.
• Disposed of chargeable assets in the year → route ng-cgt.
• Entity unclear (sole / BN / RC / partnership / incorporated trustee) → route ng-formation.
• Books not on IFRS for SMEs or FRC-approved framework → flag for bookkeeping review.
• Always final → ng-return-assembly.

Section 2 — Workflow runbook (order of operations)

Strict order. Do not narrate steps.

1. Opening — one-line greeting + flow summary + reviewer reminder (ICAN/ANAN/CITN), then launch the refusal sweep.
2. Refusal sweep — single ask_user_input_v0 call with the 5 questions in Section 5.1.
3. Document dump — ask user to upload everything at once (bank statements, invoices issued / received, WHT credit notes, prior FIRS / LIRS returns, CAC certificate, TIN slip, payroll schedules). Do not insist on bank statements alone.
4. Inference pass — parse every document; extract turnover, expenses, WHT suffered, prior tax paid, employee headcount.
5. Regime classification — apply Section 4 decision tree using inferred turnover + sweep answers + period start/end (pre-2026 vs from-2026).
6. Confirmation — show inferred summary + proposed regime + downstream-skill list; invite corrections.
7. Gap filling — ask_user_input_v0 only for items documents cannot answer (state of residence for PIT, TIN status, Tax Pro-Max access, CAC details).
8. Handoff — produce Section 6 summary and invoke ng-return-assembly.

Operating principles: use ask_user_input_v0 for multi-choice; free text only for names / TIN / RC number / BVN-linked details. Batch up to 3 related independent questions. Never re-ask documents-visible facts. Spell out Nigerian acronyms on first mention (e.g., "Federal Inland Revenue Service (FIRS)", "Lagos State Internal Revenue Service (LIRS)"). All amounts in NGN.

---

Section 3 — Required inputs

Some inferred from documents, the rest gap-filled. All mandatory before handoff.

• Identity / registration: legal name, Tax Identification Number (TIN — issued by JTB and now harmonised with FIRS / state IRS), Bank Verification Number (BVN) where relevant for PIT (FA 2019 / FA 2020), CAC registration (BN number for sole proprietors; RC number for limited companies), date of incorporation / registration.
• State of residence (PIT only — determines which State IRS administers; LIRS for Lagos, FCT-IRS for Abuja FCT, otherwise the relevant SIRS).
• Entity: Sole trader (no CAC registration) / BN (CAC business name) / RC (Ltd or PLC) / Partnership / Incorporated Trustee. RC: SCUML status if applicable.
• Revenue: current FY gross turnover, monthly turnover detail, domestic vs export mix (exports zero-rated for VAT under FA 2019 / NTA 2025), assessable profit / loss.
• Tax history: prior-year PIT (Form A) or CIT self-assessment, outstanding tax liabilities or refunds, audit history with FIRS / SIRS, any tax clearance certificate (TCC) issues.
• Operational: employee count (PAYE obligation), VAT-registered status, FIRS Tax Pro-Max active, pension scheme membership (PRA 2014), NHF / NHIA / ITF / NSITF contribution history.
• Documents: bank statements (NGN + USD where relevant), invoices issued and received, WHT credit notes (the most common WHT credit evidence; 5% / 10% standard rates pre-NTA 2025), prior returns (Form A, CIT self-assessment, VAT 002, PAYE Form H1), CAC certificate, TIN slip, payroll register, audited financial statements (RCs only).

---

Section 4 — Regime decision tree with thresholds and citations

All thresholds reflect the rules current as at the period being prepared. Many returns being worked in 2026 still cover periods governed by CITA / PITA / FA 2019–2023. The Nigeria Tax Act 2025 (NTA 2025) is effective 1 January 2026 and applies to financial years beginning on or after that date — earlier periods stay on the prior framework. Section 6 always records which regime stack was applied.

4.1 Residency gate — PITA s.2 (individuals); CITA s.13 (companies)

• Individual resident = (i) domiciled in Nigeria during the year, OR (ii) present ≥ 183 days in any 12-month period, OR (iii) employed by the Nigerian government or a Nigerian-resident employer.
• Company resident = (i) incorporated in Nigeria (Nigerian company), OR (ii) management and control exercised in Nigeria.
• Non-residents (without a Nigerian fixed base / significant economic presence under FA 2019 / NTA 2025) → REFUSE and route to a separate non-resident flow.

4.2 Entity gate — sole trader / BN vs RC

• Sole trader (no CAC) or BN (CAC Part B registered business name): Not a separate legal entity. Owner pays PIT on business profits via self-assessment with the State Internal Revenue Service of residence (LIRS / FCT-IRS / SIRS). Route ng-personal-income-tax.
• Private limited company (RC, "Ltd") or PLC: Separate legal entity. Pays CIT to FIRS. Owner separately pays PIT on salary / dividends. Route ng-cit.
• Partnership: Profits taxed at partner level under PITA. Route ng-personal-income-tax per partner.
• Incorporated Trustee (Part F CAC) / cooperative / NGO: out of scope here — refuse and route to specialist.

4.3 CIT band gate — CITA s.40 (pre-NTA 2025) / NTA 2025 (from 1 Jan 2026)

The "small company" definition has shifted twice. Use the rule in force for the period being prepared.

Period	Small company definition	Small co. CIT	Medium CIT	Large CIT	Source
Pre-FA 2019	n/a	30% flat	30%	30%	CITA s.40
FA 2019 → FY 2025	Turnover ≤ N25m	0%	20% (turnover N25m–N100m)	30% (> N100m)	FA 2019 s.16
NTA 2025 (FY starting on/after 1 Jan 2026)	Turnover ≤ N100m AND fixed assets ≤ N250m	0%	20% (N100m–N1bn)	30% + 4% Development Levy (> N1bn)	NTA 2025

• Route ng-cit for all RCs. Small companies still file (CIT-nil return) — they do not escape the filing obligation.
• Minimum tax: historically applied at 0.5% of gross turnover where computed tax was lower; NTA 2025 retains a development-levy-style backstop for large companies. Reviewer to confirm for the specific period.

4.4 PIT computation gate — PITA Sixth Schedule

• Progressive rates 7% / 11% / 15% / 19% / 21% / 24% on bands stacked from N300,000 to > N3,200,000.
• Consolidated Relief Allowance (CRA) = max(N200,000, 1% × gross income) + 20% × gross income.
• Minimum tax (PIT) = 1% of gross income where computed PIT after CRA and reliefs would be lower.
• Route ng-personal-income-tax for the computation; defer state-specific filing portal nuances to that skill.

4.5 VAT gate — VATA as amended by FA 2019 / FA 2020 / FA 2023; NTA 2025 carry-forward

• Threshold: N25m taxable turnover in the trailing-12 months (FA 2019 s.46). Below threshold = exempt from VAT registration and from VAT charging obligations, but still no input VAT recovery.
• Rate: 7.5% standard (FA 2019). Exports zero-rated. Basic food, medical and educational items exempt (VATA First Schedule, expanded by FA 2019).
• Above threshold or voluntarily registered → route ng-vat and ensure FIRS Tax Pro-Max VAT module is active.

4.6 PAYE / employer gate — PITA s.81; Operation of PAYE Regulations 2002

Any employees → withhold PAYE monthly and remit to the employee's State Internal Revenue Service by the 10th of the following month. Route ng-paye + ng-payroll. Statutory deductions (pension PRA 2014 8% employee + 10% employer; NHF 2.5%; NHIA where applicable; ITF 1% of payroll for employers with ≥ 5 staff or ≥ N50m turnover; NSITF 1%) → route ng-statutory-deductions.

4.7 Withholding-tax gate — CITA s.78–82; PITA s.69–73; WHT Regulations 1997 (as amended)

WHT obligation arises if the taxpayer (RC always; sole trader where appointed agent) pays:

• Contracts / supplies — 5% (companies) / 5% (individuals).
• Professional services / consultancy / management — 10% / 5%.
• Rent — 10% (companies and individuals).
• Royalties / interest / dividends — 10% (5% under several DTTs).
• Non-resident payments — 10% subject to DTT.

NTA 2025 streamlines WHT rates and broadens exemptions for small companies. Reviewer to confirm the matrix for the relevant period. Route ng-wht whenever the taxpayer has paid or received any of the above.

4.8 CGT gate — CGTA s.2; FA 2021 (digital assets); NTA 2025

Capital gains on disposal of chargeable assets (land, buildings, shares above the FA 2021 N100m / 100,000-share thresholds, digital assets) → 10% CGT. Route ng-cgt if any disposals in the year.

4.9 Filing-channel gate — FIRS Tax Pro-Max; state IRS portals

• All FIRS returns (CIT, VAT, WHT, CGT for companies) file through FIRS Tax Pro-Max (mandatory since 2022). Confirm access.
• PAYE and PIT returns file through the State IRS portal (LIRS eTax for Lagos; FCT-IRS for Abuja; relevant SIRS otherwise). Confirm access and state of residence.

If access missing → flag in open_flags; reviewer onboards before filing.

Section 5 — Questions to ask the user

Use ask_user_input_v0. Batch where independent.

5.1 Refusal sweep (one batched ask_user_input_v0 call, 5 single-select questions)

• Q1 Residency (period being prepared): Full-year Nigerian resident | Foreigner present ≥ 183 days | Part-year | Non-resident with Nigerian-source income only.
• Q2 Entity: Sole trader (no CAC) | Business Name / BN (CAC Part B) | Private limited company / RC (Ltd) | Partnership | Incorporated Trustee / NGO | Not sure.
• Q3 Period being prepared: Calendar year 2025 (pre-NTA) | FY ending in 2025 (pre-NTA) | FY starting on/after 1 Jan 2026 (NTA 2025) | Multiple periods.
• Q4 Current-FY turnover (NGN): ≤ N25m | N25m–N100m | N100m–N1bn | > N1bn | Not sure (infer from docs).
• Q5 State of residence (PIT only) / state of operation (RC): Lagos | FCT (Abuja) | Rivers | Other state — please name | Multiple states.

Routing:

Answer	Action
Q1 full-year	continue
Q1 foreigner ≥ 183d	continue; reviewer to verify DTT / significant economic presence rule
Q1 part-year	continue with caution; flag split-year sourcing
Q1 non-resident with NG-source only	REFUSE — separate non-resident workflow needed
Q2 sole / BN	route ng-personal-income-tax; no ng-cit
Q2 RC	route ng-cit; owner PIT only if salary / dividends drawn
Q2 partnership	route ng-personal-income-tax per partner; flag for split
Q2 Incorporated Trustee	REFUSE; route to specialist
Q2 not sure	route ng-formation first
Q3 calendar 2025 / FY ending 2025	pre-NTA stack: CITA + PITA + FA 2019–2023
Q3 FY starting on/after 1 Jan 2026	NTA 2025 stack
Q3 multiple periods	run each period through the appropriate stack
Q4 ≤ N25m	small company (FA 2019) OR below VAT threshold for sole/BN
Q4 N25m–N100m	pre-NTA: medium (CIT 20%); NTA 2025: still small (CIT 0%) — period flag critical
Q4 N100m–N1bn	pre-NTA: large (CIT 30%); NTA 2025: medium (CIT 20%)
Q4 > N1bn	large in both regimes (CIT 30%); NTA 2025 adds 4% Development Levy
Q4 not sure	defer to inference
Q5 Lagos	PIT filings via LIRS eTax
Q5 FCT	PIT filings via FCT-IRS
Q5 other state	PIT filings via that SIRS; flag portal access
Q5 multiple states	apportion by residence rule (PITA s.2(2)); flag for reviewer

5.2 Secondary batched questions

• Q6 VAT status: Registered (issuing VAT invoices) | Not registered | Not sure.
• Q7 Employees in the period: None | 1–4 | 5–20 | > 20.
• Q8 TIN status: Have FIRS / JTB TIN (active) | Have CAC but no TIN | No registration yet.
• Q9 Pension / statutory schemes: All current (PenCom-compliant + NHF) | Some current | None.

Routing:

Answer	Action
Q6 registered	route ng-vat
Q6 not registered but turnover > N25m	flag VAT registration overdue; route ng-vat; reviewer to register
Q6 not sure	defer to inference; default conservatively to "registration required" if turnover > N25m
Q7 ≥ 1 employee	route ng-paye + ng-statutory-deductions + ng-payroll
Q7 ≥ 5 employees	additionally flag ITF (1% of payroll) and NSITF (1%) obligations
Q8 no TIN	route to ng-formation onboarding fallback (Section 8); cannot file without TIN
Q9 some / none	route ng-statutory-deductions to remediate; flag for reviewer

5.3 WHT and CGT questions

• Q10 In the period did you pay Nigerian suppliers for contracts, professional services, rent, or non-resident suppliers? Yes (contracts) | Yes (services) | Yes (rent) | Yes (non-resident) | Multiple | No.
• Q11 Did you dispose of land, buildings, shares above the FA 2021 thresholds, or digital assets in the period? Yes | No | Not sure.

Any "Yes" on Q10 → route ng-wht. Reviewer confirms whether sole trader is an appointed WHT agent (CITA s.78–82 applies automatically to companies). Q11 yes → route ng-cgt.

5.4 Tax Pro-Max / state portal access

• Q12 FIRS Tax Pro-Max access? Yes (active) | No (never logged in) | Started but hit issues.
• Q13 State IRS portal access (LIRS eTax / FCT-IRS / SIRS)? Yes | No | N/A (RC with no employees and no PIT due).

"No" or "issues" → flag in open_flags. Tax Pro-Max is the only FIRS filing channel; the relevant state portal is the only PAYE / PIT channel.

Section 7 — NTA 2025 transitional handling (pre-2026 vs from-2026)

The Nigeria Tax Act 2025 is effective for financial years beginning on or after 1 January 2026. Earlier periods stay on the prior framework. Always record which regime stack applies and apply rules consistently within a single period.

Item	Pre-NTA 2025 (FY ending ≤ Dec 2025)	NTA 2025 (FY starting ≥ Jan 2026)
Statutes	CITA, PITA, VATA, CGTA, FA 2019 / 2020 / 2021 / 2023	NTA 2025 (consolidated)
Small co. threshold	Turnover ≤ N25m (FA 2019)	Turnover ≤ N100m AND fixed assets ≤ N250m
Small co. CIT	0%	0%
Medium co. band	N25m–N100m	N100m–N1bn
Medium co. CIT	20%	20%
Large co. CIT	30%	30%
Development Levy	n/a (Tertiary Education Tax / NITDA / NASENI / police levy as separate items)	4% consolidated levy on large companies
Minimum tax	0.5% of turnover where applicable	NTA 2025 simplifies; reviewer to confirm
WHT rates	WHT Regulations 1997 + FA amendments	NTA 2025 simplifies and exempts small companies
VAT	VATA + FA 2019 (7.5%)	NTA 2025 carries 7.5% forward (subject to amendment)
Filing channel (federal)	FIRS Tax Pro-Max	FIRS Tax Pro-Max
Filing channel (state PIT/PAYE)	State IRS portal	State IRS portal

Mixed periods (e.g., FY ending 31 March 2026 straddling 1 Jan 2026 cutover) are handled by ng-return-assembly, not by this intake — flag the straddle in open_flags and let the assembly skill do the apportionment under NTA 2025 transitional provisions.

Section 8 — State-level considerations (LIRS vs other SIRS)

PIT and PAYE are state taxes under PITA. The state where the taxpayer is resident (PIT) or where the employee resides (PAYE) administers and collects.

State	Administering authority	Portal	Notes
Lagos	Lagos State Internal Revenue Service (LIRS)	eTax (etax.lirs.net)	Most developed state portal; aggressive enforcement; tax audit cycle ~2 years; consent letters required for inter-state moves
Federal Capital Territory (Abuja)	FCT Internal Revenue Service (FCT-IRS)	FCT-IRS e-portal	FCT residents file here, not FIRS
Rivers	Rivers State IRS	RIRS portal
Kano / Kaduna / Oyo / others	State IRS of residence	Varies	Some states still accept paper filings; flag for reviewer
Cross-border residence	Apportionment rule (PITA s.2(2))	n/a	Tax residence determined by principal place of residence on 1 January of the year

Notes:

• For sole traders / BN, PIT is filed where the individual is resident, not where the business is registered or operates.
• For RC employees, PAYE is remitted to each employee's state of residence — a Lagos-based RC with staff in Ogun must remit Ogun PAYE to Ogun SIRS.
• TCC (Tax Clearance Certificate) is issued by the relevant state IRS for PIT and by FIRS for CIT.

If the state is anything other than Lagos / FCT / Rivers, flag for reviewer — portal availability and procedural rules vary widely.

---

Section 9 — Onboarding fallback (user has no TIN yet)

If Q8 returns "No registration yet" or no TIN is found in documents, stop the regime-classification flow and run this fallback before any further work:

1. Confirm entity intent: sole / BN / RC. If unsure, route ng-formation first.
2. CAC registration (if BN or RC): the user must register the business with the Corporate Affairs Commission at cac.gov.ng before a TIN can be issued. BN takes ~2–5 working days; RC takes ~5–10 working days.
3. TIN issuance:
   • RC: TIN is now auto-issued by FIRS upon CAC incorporation (Joint Tax Board harmonisation, 2021 onward). Confirm via Tax Pro-Max lookup.
   • Sole / BN / individual: Apply for TIN via JTB / FIRS / state IRS. Individuals can use BVN-linked auto-issuance where supported. Lagos residents: LIRS issues Tax ID on first eTax registration.
4. Tax Pro-Max / state portal onboarding: create account, link TIN, link bank account for direct debit.
5. VAT registration (if turnover > N25m or voluntary): separate Tax Pro-Max workflow once TIN is active.
6. PAYE registration (if employees): register with the relevant state IRS as an employer; obtain Employer Tax ID.

Until TIN is active, no return can be filed. Flag onboarding_required in open_flags and refer the user to a CITN-registered tax practitioner or ICAN/ANAN Chartered Accountant to walk through CAC + JTB / FIRS / state IRS registration.

---

Section 10 — Conservative defaults

When uncertain, prefer the safer (higher-tax / stricter-compliance) outcome and flag. All defaults visible to reviewer in conservative_defaults_applied.

Ambiguity	Conservative default
Period straddles 1 Jan 2026 cutover	Apply pre-NTA stack to pre-cutover portion, NTA 2025 to post-cutover; flag for ng-return-assembly
Turnover near N25m (FA 2019) or N100m (NTA 2025) threshold	Assume above threshold → medium band + VAT registration required
Entity unclear (sole vs BN vs RC)	Treat as sole trader for PIT default; flag ng-formation
Residency borderline (~180 days)	Assume non-resident → REFUSE for individual returns
WHT-agent status unclear (sole trader not clearly appointed)	Assume WHT obligation exists for any qualifying payment; flag
Pension / NHF / NHIA compliance unclear	Assume non-compliant → flag remediation; defer to ng-statutory-deductions
Minimum tax (PIT 1% / CIT 0.5%) borderline	Apply minimum tax; reviewer can release if computed tax exceeds it
State of residence unclear	Default Lagos (LIRS) only if documents support; otherwise ask — never guess
Tax Pro-Max access unknown	Assume not active; flag for onboarding
Capital vs expense unclear	Capitalise + flag (capital allowance treatment)
Foreign-currency invoice without CBN rate	Use CBN official rate on invoice date; flag if no rate available

---

Section 11 — Refusal handling

Refusals fire from the refusal sweep or during inference. Protocol: stop the workflow, state the reason in one sentence, recommend a CITN-registered tax practitioner or ICAN / ANAN Chartered Accountant (or an audit firm where audited financials are needed), do not work around.

In-scope refusals:

• Non-resident with Nigerian-source income only (separate flow needed).
• Part-year residence with split sourcing complexity beyond a single relocation.
• Incorporated Trustees / NGOs / cooperatives / Public Benefit Organisations.
• Large companies with consolidated reporting, transfer-pricing audit exposure (TP Regulations 2018), or country-by-country reporting obligations.
• RCs requiring audited financial statements (CAMA 2020 s.402) where audit is not yet complete — refuse until audit signed.
• Oil and gas companies (PPTA / NUPRC regime) — out of scope.
• Free Zone Enterprises under NEPZA / OGFZA — out of scope.
• Pioneer-status companies during pioneer period (Industrial Development (Income Tax Relief) Act) — refuse; specialist territory.

Sample: "Stop — your RC's financial statements have not yet been audited. CAMA 2020 s.402 requires audited accounts for the CIT filing, and FIRS will reject a Tax Pro-Max submission without them. You need an ICAN-registered auditor to sign off before I can prepare the return."

---

Section 12 — Self-checks before handoff

Run all 15 before invoking ng-return-assembly. Any failure → fix, do not hand off.

1. Refusal sweep used ask_user_input_v0, not prose.
2. Residency confirmed (full-year, ≥ 183d foreigner with flag, or refused).
3. Entity type set (sole / BN / RC / partnership).
4. Regime stack chosen (pre-NTA vs NTA 2025) and recorded.
5. Period turnover recorded in NGN with bucket band.
6. Regime selected with reason traced to (a) entity, (b) turnover, (c) period.
7. VAT status set; registration_overdue_flag set if turnover > N25m and not registered.
8. Employee count set; ng-paye + ng-statutory-deductions + ng-payroll in downstream list if > 0.
9. ITF / NSITF flags set if ≥ 5 employees or ≥ N50m payroll.
10. WHT exposure checked; ng-wht in list if applicable.
11. CGT disposals checked; ng-cgt in list if applicable.
12. State of residence captured (PIT path) or state of operation (RC path).

Section 13 — Final handoff to ng-return-assembly

Once gap-filling and self-checks pass, output a short handoff message naming (a) taxpayer + entity + state + TIN + Tax Pro-Max status, (b) regime stack + regime selected with the headline computation citation, (c) downstream skills in run-order, (d) skills explicitly not running and why, (e) reviewer reminder. Then invoke ng-return-assembly with the Section 6.2 package.

Example (sole trader, Lagos, FY 2025 pre-NTA, no employees, below VAT threshold):

Intake complete. Adebayo Okonkwo, sole trader, Lagos resident, TIN active, LIRS eTax onboarded, no CAC (sole, not BN). Period: CY 2025, pre-NTA stack. Turnover N18m. Regime: PIT progressive (PITA Sixth Schedule); CRA = max(N200k, 1% × gross) + 20% × gross; minimum tax 1% if computed PIT lower. Running: ng-personal-income-tax, ng-wht (Q10 yes on services received), ng-return-assembly. Not running: ng-cit (sole trader), ng-vat (below N25m), ng-paye / ng-statutory-deductions / ng-payroll (no employees), ng-cgt (no disposals). Needs CITN-registered tax practitioner sign-off before LIRS eTax submission. Handing off now.

Example (RC, FY ending 31 Dec 2026, NTA 2025 stack, 8 employees, above VAT threshold):

Intake complete. Pomelo Tech Ltd, RC 1234567, registered office Lagos, TIN active, Tax Pro-Max active. Period: FY ending 31 Dec 2026, NTA 2025 stack. Turnover N420m, fixed assets N80m → medium company. Regime: CIT 20% (NTA 2025). Running: ng-cit, ng-vat (registered), ng-paye + ng-statutory-deductions + ng-payroll (8 employees; ITF applicable as headcount ≥ 5), ng-wht (paying both contractors and rent), ng-return-assembly. Not running: ng-personal-income-tax (separate workflow for owner salary), ng-cgt (no disposals). Needs ICAN-registered Chartered Accountant sign-off and audited financials (CAMA 2020 s.402) before Tax Pro-Max submission. Handing off now.
