# Review kit: Trinidad VAT

Thank you for reviewing this Guide. This kit is one file with three parts: how
to use it, an interview prompt for your AI, and the Guide itself.

## How to use this kit (3 steps, about 15 minutes)

1. Open the AI you already use (ChatGPT, Claude, Gemini, anything that reads
   markdown) and paste in everything from "INTERVIEW PROMPT" below, including
   the Guide at the end.
2. Your AI interviews you like a colleague, one question at a time. Just talk:
   war stories, walk-throughs, the mistakes you catch. No writing required.
3. Your AI writes your answers up as a single markdown file. Hand it back at
   openaccountants.com/skills/trinidad-vat/handback (also linked from the Guide
   page: "Hand back your file"). What you added is published under your name
   and credential.

If your AI cannot produce the exact output format, hand back whatever you have:
a revised Guide file, a worksheet, or plain notes. We take those too, and a
person reviews them by hand. The format below is the one we can apply straight
away.

# INTERVIEW PROMPT (paste from here down into your AI)

You are interviewing a practising accountant about how they actually do the
work covered by the attached Guide ("Trinidad VAT", slug `trinidad-vat`).
Interview them like a colleague doing a handover. Do not lecture. Ask ONE
question at a time and wait for the answer. Chase war stories and specifics:
what kind of client, which portal step, how big the penalty was.

The rates, thresholds, and citations are our job; we refresh those from primary
sources. Capture ONLY what is NOT derivable from law:

- order of operations, and what a wrong order corrupts
- what to ask a client before computing anything
- what to assume when a fact is unknown, and how it gets flagged
- the most-missed traps, with penalty size and who falls in
- how the portal or filing channel actually behaves
- what has to reconcile before anyone signs
- when to refuse the work and hand it to a human specialist

If the accountant corrects a rate, threshold, or deadline in the Guide along
the way, record it in the FACT CORRECTIONS table, but do not steer the
interview toward numbers.

## Questions to work through

Ask these in order, one at a time. Skip any the accountant has already covered;
follow up where a story has specifics worth pinning down. Each question is
tagged with the method slot(s) it feeds.

1. [sequence] Walk me through the last VAT return you prepared, start to finish. What did you open first, and why that order?
2. [intake_questions] [evidence] A new client hands you nothing but a bank statement. What do you do before you'll classify a single line?
3. [pattern_library] Which bank-statement line gets misclassified most often in your experience? What does it look like and where should it actually go?
4. [scope_gate] Tell me about a client you refused or referred out. What about their VAT situation made you stop?
5. [trap] When you review a return someone else drafted, what mistake do you catch most often?
6. [conservative_default] When you can't tell if a sale is domestic or cross-border, what do you assume, and how do you mark it?
7. [cross_check] Before you sign, what has to reconcile with what, and how close is close enough?
8. [filing_mechanics] Walk me through filing on the actual portal. What surprises first-timers: the order of forms, what locks, what you can't undo?
9. [judgment_rule] Ever had a client on a simplified scheme where the "simplification" made things worse? How do you decide who belongs on it?
10. [trap] What's the real penalty story you tell clients, the one that actually happened?
11. [evidence] Which claims will you draft from a bank statement but never file without the underlying paper?
12. [unsettled_law] Anything in VAT right now you deliberately won't finalise because the rules are moving?

## Method slots (for tagging the write-up)

- `scope_gate` (Scope gate and refusals): when to stop and send the client to a human
- `sequence` (Order of operations): what order to do things in, and what a wrong order corrupts
- `intake_questions` (Client intake questions): what to ask a client before computing
- `evidence` (Documents and evidence): which documents to insist on, and what is draft-grade vs file-grade
- `judgment_rule` (Judgment rules): how a practitioner actually picks when the law allows two routes
- `conservative_default` (Conservative defaults): what to assume when a fact is unknowable at draft time
- `trap` (Traps and most-missed items): the mistakes everyone makes, what they cost, and who falls in
- `filing_mechanics` (Portal and filing mechanics): how submission actually works: channel, order, what locks
- `cross_check` (Cross-checks before signing): what has to reconcile with what before delivery, and how close is close enough
- `pattern_library` (Pattern library): how messy real-world data (bank lines, payout platforms) maps to tax categories
- `edge_case` (Edge-case playbook): the client situations that change the method, not just the numbers
- `unsettled_law` (Unsettled-law flags): what not to finalise right now, and why
- `handback_protocol` (Hand-back protocol): what the finished working paper contains and who reviews it

## Output format: oa-handback v1

When the interview is done, write the answers up as ONE markdown file in
exactly this shape. Fill in the reviewer's real name, credential, and email
(ask for them at the end if they have not come up). Every method block gets a
`### [method:<slot>]` heading where `<slot>` is one of the 13 slot ids
above. Keep `guide_slug` and `guide_version` exactly as given. Omit any
section the interview produced nothing for, but keep the headings that remain
exactly as shown. The `fact_key` column may be left blank when unknown.

## FLAGS

- [refer] <situations to escalate to a human>

## NOTES
<anything that did not fit a method slot or a fact correction>
```

If for any reason you cannot produce this exact format, output the accountant's
corrections and methods as clear plain notes instead. The hand-back page
accepts plain notes and revised Guide files too; this format is an
optimization, never a gate.

## Confidence Tier Definitions

Every rule in this skill is tagged with a confidence tier:

- **[T1] Tier 1 -- Deterministic.** Apply exactly as written. No reviewer judgement required.
- **[T2] Tier 2 -- Reviewer Judgement Required.** Flag the issue and present options. A licensed accountant must confirm before filing.
- **[T3] Tier 3 -- Out of Scope / Escalate.** Skill does not cover this. Do not guess. Escalate to licensed accountant and document the gap.

## Step 0: Client Onboarding Questions

Before classifying ANY transaction, you MUST know these facts about the client. Ask if not already known:

1. **Entity name and BIR file number** [T1] -- unique taxpayer identifier
2. **VAT registration number** [T1] -- assigned by BIR upon registration
3. **VAT filing period** [T1] -- bi-monthly (standard: Jan-Feb, Mar-Apr, May-Jun, Jul-Aug, Sep-Oct, Nov-Dec)
4. **Industry/sector** [T2] -- impacts classification (energy sector, manufacturing, financial services)
5. **Does the business make exempt supplies?** [T2] -- If yes, partial input tax attribution required
6. **Does the business import goods?** [T1] -- impacts customs VAT treatment
7. **Excess credit brought forward** [T1] -- from prior period
8. **Is the business in the energy/petrochemical sector?** [T2] -- special regimes may apply

**If items 1-3 are unknown, STOP. Do not classify any transactions until registration status and period are confirmed.**

## Step 1: VAT Rate Structure [T1]

**Legislation:** VAT Act 1989, Section 6; First Schedule; Second Schedule.

### Standard Rate

- **12.5%** — Standard rate on all taxable supplies and imports not otherwise specified [T1]  _(VAT Act 1989, Section 6)_

**Standard Rate table**  _(VAT Act 1989, Section 6)_

| --- | --- |
| 12.5% | Standard rate on all taxable supplies and imports not otherwise specified [T1] |

### Zero-Rated Supplies (0%) [T1]

- **Zero-rated supplies list** — Exports of goods; International transport of goods and passengers; Supplies of unprocessed food (basic food basket items -- rice, flour, sugar, milk, bread, fresh fruit, vegetables, fresh meat, fresh fish); Agricultural inputs (fertilizers, animal feed, seeds); Prescription drugs and pharmaceutical products; Crude oil and natural gas (upstream supplies); Printed books and newspapers; Water (piped, domestic use)  _(VAT Act, First Schedule)_

### Exempt Supplies (No VAT, No Input Credit) [T1]

- **Exempt supplies list** — Financial services (interest, foreign exchange, life insurance premiums); Residential rental (unfurnished); Medical and dental services (public and private); Educational services (approved institutions); Postage stamps (at face value); Burial and cremation services; Land (sale of bare land)  _(VAT Act, Second Schedule)_

### 2a. Determine Transaction Type [T1]

- **Determine Transaction Type** — Sale (output VAT) or Purchase (input VAT). Salaries, PAYE, NIS contributions, Health Surcharge, loan repayments, dividends = OUT OF SCOPE (never on VAT return)  _(VAT Act, Section 2 (definitions of taxable supply))_

### 2b. Determine Counterparty Location [T1]

- **Counterparty Location categories** — Domestic (Trinidad and Tobago): supplier/customer in TT. CARICOM: Jamaica, Barbados, Guyana, Suriname, Belize, Bahamas, Haiti, OECS states. International: all other countries

### 2c. Determine VAT Rate [T1]

- **rate calculation** — rate = vat_amount / net_amount * 100. Normalize: 0% (zero-rated), 12.5% (standard), or exempt. Boundaries: <= 1% = 0%; >= 10% = 12.5%  _(VAT Act, Section 6)_

### 2d. Determine Expense Category [T1]

- **Expense category definitions** — Capital goods: equipment, machinery, vehicles, furniture. Inventory for resale: goods purchased for direct resale. Operating expenses/overheads: everything else

## Step 3: VAT Return Form Structure [T1]

**The VAT return (Form VAT 1) is filed bi-monthly.**

### Part A -- Output Tax

**Part A -- Output Tax table**

| Box | Description |
| --- | --- |
| 1 | Total value of taxable supplies at 12.5% |

| Box | Description |
| --- | --- |
| 9 | VAT on local purchases of goods and services |
| 10 | VAT on imports (from customs entries, claimable portion) |
| 11 | Total input tax (Box 9 + Box 10) |

| --- | --- | --- |
| 14 | Net VAT (Box 8 - Box 13) |  |
| 15 | Credit brought forward |  |
| 16 | Net amount payable / (refundable) (Box 14 - Box 15) |  |

## Step 4: Reverse Charge on Imported Services [T1]

**Legislation:** VAT Act, Section 7 (imported services).

When a Trinidad and Tobago registered person receives services from a non-resident supplier:

1. The recipient must self-assess VAT at 12.5% on the value of the imported service [T1]
2. Report the self-assessed VAT as output tax (Box 7) [T1]
3. If the service is used in making taxable supplies, claim input tax (Box 9) [T1]
4. Net effect: zero for fully taxable businesses [T1]

### Exceptions to Reverse Charge [T1]

- **Exceptions list** — Out-of-scope categories (wages, dividends, loan repayments): NEVER reverse charge. Services that would be exempt if supplied domestically: reverse charge applies but NO input credit. Services consumed entirely outside Trinidad and Tobago: NOT subject to VAT

### Blocked Input Tax (No Recovery) [T1]

- **Blocked input tax categories** — The following have ZERO VAT recovery: Entertainment -- meals, hospitality, amusement (unless business is in the hospitality trade) [T1]; Motor cars -- purchase, lease, maintenance of motor cars (exception: car rental, taxi, driving school businesses) [T1]; Club subscriptions -- sporting, social, recreational [T1]; Personal/domestic use -- any goods or services for personal consumption [T1]; Goods/services for making exempt supplies -- no input credit [T1]  _(VAT Act, Section 16; Section 17)_

### Registration-Based Recovery [T1]

- **Registration-based recovery rules** — VAT-registered making taxable supplies: full recovery (subject to blocked categories). Non-registered: NO recovery. Registered making only exempt supplies: NO recovery

### Partial Exemption / Apportionment [T2]

- **Recovery % formula** — If the business makes both taxable and exempt supplies: Directly attributable input tax: allocate to taxable or exempt. Common input tax: apportion using: Recovery % = (Taxable Supplies / Total Supplies) * 100. Flag for reviewer: apportionment must be confirmed by licensed accountant.  _(VAT Act, Section 16(2))_

## Step 6: Key Thresholds [T1]

- **Mandatory VAT registration** — Annual taxable supplies exceeding TTD 600,000  _(VAT Act, Section 9 (registration threshold))_
- **Voluntary registration** — Below TTD 600,000 (may register voluntarily if making taxable supplies)  _(VAT Act, Section 9 (registration threshold))_

**Key Thresholds table**  _(VAT Act, Section 9 (registration threshold))_

| Threshold | Value |

## Step 10: Energy Sector Special Rules [T2]

- **Energy sector special considerations** — Trinidad and Tobago's economy is heavily dependent on the energy sector. Special considerations: Upstream oil and gas (exploration, production): supplies of crude oil and natural gas are zero-rated [T1]; Services to energy companies: generally taxable at 12.5% [T1]; LNG exports: zero-rated as exports [T1]; Petrochemical manufacturing: standard 12.5% applies to domestic sales; exports zero-rated [T1]; Capital equipment imported for energy sector: may qualify for customs duty concessions but VAT still applies at 12.5% (input credit available) [T2]; Flag for reviewer: energy sector transactions often involve complex contractual arrangements. Verify supply classification.  _(VAT Act, First Schedule; Petroleum Taxes Act)_

## Step 11: CARICOM Trade [T2]

- **CARICOM trade rules** — Goods imported from CARICOM member states: VAT at 12.5% collected by customs (same as other imports) [T1]; Services from CARICOM providers: reverse charge at 12.5% [T1]; Exports to CARICOM: zero-rated (same as other exports) [T1]; CARICOM does NOT have an EU-style single-market VAT system -- each country collects its own VAT independently [T1]; Double-taxation relief may apply to certain transactions [T2] -- flag for reviewer  _(VAT Act; CARICOM Revised Treaty of Chaguaramas)_

## PROHIBITIONS [T1]

- **Prohibitions list** — NEVER let AI guess VAT classification -- it is deterministic from facts; NEVER allow input tax credit on blocked categories (entertainment, motor cars, clubs); NEVER apply reverse charge to out-of-scope categories (salaries, NIS, PAYE); NEVER allow non-registered persons to claim input tax credits; NEVER confuse zero-rated (input credit allowed) with exempt (NO input credit); NEVER ignore the TTD 600,000 registration threshold; NEVER file a return without verifying the VAT registration number; NEVER treat CARICOM imports differently from other imports for VAT purposes (same rate applies); NEVER compute any number -- all arithmetic is handled by the deterministic engine, not Claude

### EC1 -- Imported services from US software provider [T1]

**Situation:** TT registered business subscribes to US-based cloud software. No VAT on invoice.
**Resolution:** Reverse charge applies. Self-assess VAT at 12.5%. Report as output tax (Box 7). Claim input tax (Box 9) if used for taxable supplies. Net effect = zero.
**Legislation:** VAT Act, Section 7.

### EC2 -- Motor vehicle for delivery fleet [T2]

**Situation:** Client purchases a delivery van for transporting goods.
**Resolution:** Delivery vehicles (vans, trucks) designed for goods transport are generally NOT blocked under the motor car restriction. Motor car restriction applies to passenger vehicles. Flag for reviewer: confirm vehicle classification (motor car vs. commercial vehicle).
**Legislation:** VAT Act, Section 17.

### EC3 -- Mixed supply: financial services + advisory fees [T2]

**Situation:** Bank charges include both exempt interest and taxable advisory/management fees.
**Resolution:** Split by nature. Interest = exempt. Advisory/management fees = taxable at 12.5%. Input tax on costs attributable to advisory services is recoverable. Flag for reviewer to confirm split.

### EC4 -- Credit notes [T1]

**Situation:** Client issues a credit note for returned goods.
**Resolution:** Reduce output tax by the VAT on the credit note. Report net figures. Do not create a separate negative entry in a different box.

### EC5 -- Furnished residential rental [T2]

**Situation:** Client rents out a furnished apartment.
**Resolution:** Unfurnished residential rental is exempt. Furnished rental may be treated as a taxable supply (it is closer to accommodation/hotel). Flag for reviewer: confirm treatment based on nature and duration of rental.
**Legislation:** VAT Act, Second Schedule.

### EC6 -- VAT refund processing [T2]

**Situation:** Client has excess input tax credits accumulated over multiple periods.
**Resolution:** Excess credits are carried forward. Refund claims may be filed but BIR processing can be slow (6-12 months). Flag for reviewer: advise client on refund application process and documentation requirements.
**Legislation:** VAT Act, Section 29.

### EC7 -- Imports under duty-free concessions [T2]

**Situation:** Client imports machinery under a duty-free concession from the government.
**Resolution:** Duty-free concession may waive customs duty but NOT necessarily VAT. Confirm whether the concession order specifically includes VAT relief. If VAT was paid, input credit is available. Flag for reviewer.

### EC8 -- Digital services to non-resident consumers [T2]

**Situation:** TT-based company provides digital services to consumers in other countries.
**Resolution:** Services consumed outside TT may qualify as zero-rated exports. However, the place of supply rules must be carefully considered. Flag for reviewer: confirm place of supply and whether zero-rating applies.
**Legislation:** VAT Act, Section 11 (place of supply).

### EC9 -- Construction services on real property [T1]

**Situation:** Contractor provides building renovation services.
**Resolution:** Construction services are taxable at 12.5%. Input VAT on construction materials and subcontractor services is fully recoverable for the contractor. For the property owner: input VAT recoverable only if the property is used for taxable supplies.

### EC10 -- Sale of a going concern [T2]

**Situation:** Client sells entire business as a going concern.
**Resolution:** Transfer of a going concern may be treated as outside the scope of VAT. However, this depends on the specific facts and whether the business is transferred as a whole. Flag for reviewer: confirm treatment and documentation requirements.

### Energy Sector (Detailed)

- **Energy sector detailed rules** — Upstream (exploration and production): crude oil and natural gas supplies are zero-rated [T1]; Downstream (refining, marketing): domestic sales of refined petroleum products -- subject to fuel subsidy/tax arrangements, generally VAT applies [T2]; LNG exports: zero-rated as exports [T1]; Petrochemical manufacturing: standard 12.5% on domestic; zero-rated on exports [T1]; Service companies to energy sector: 12.5% on all services [T1]; Capital equipment imported for energy operations: VAT at 12.5% at customs; input credit available [T1]; Production Sharing Contracts (PSCs): complex arrangements -- flag for specialist review [T3]  _(Petroleum Taxes Act; VAT Act)_

### Financial Services

- **Agriculture VAT treatments** — Unprocessed food (basic food basket): zero-rated [T1]; Processed food: taxable at 12.5% [T1]; Agricultural inputs: zero-rated [T1]; Fishing: unprocessed fish is zero-rated [T1]

## Step 12b: Books and Records Requirements [T1]

- **Books and records requirements** — All VAT-registered persons must maintain: Sales records: all tax invoices issued, credit/debit notes, export documentation; Purchase records: all purchase invoices with VAT breakdowns, import entries; Import records: customs declarations showing VAT paid; VAT account: summary showing output VAT collected, input VAT claimed, net position; Bank statements: reconciled to business records; Records must be retained for a minimum of 6 years; Records must be in English and available for BIR inspection  _(VAT Act, Section 55)_
