One tax administration system built for small states.
A trusted platform for modern tax administration and sustainable revenue collection. MTS brings every tax type, every taxpayer and every stage of the process into one administration platform, built around national legislation rather than around the software.
The Multi Tax Solution is an integrated tax administration system, or ITAS, for revenue authorities in small states. It covers registration, filing, payment, assessment, audit, collection and reporting.
The documents on this page are available without registration.

Why MTS?
Countries face increasing pressure to improve domestic revenue collection without raising tax rates, while the systems that support compliance and collection often remain fragmented and heavily manual. Legacy platforms, disconnected registers, and paper-based processes make it difficult to respond effectively, resulting in delays, errors, and unnecessary operational burdens. The Multi Tax Solution consolidates tax administration into a single platform aligned with national legislation, enabling revenue authorities to collect, manage, and report revenue more effectively.
The conditions this is built for
A date set in law
A new regime has an implementation deadline. The systems intended to support it will not be ready by that date.
Three systems, one taxpayer
Registration, payments and arrears are held in different systems. Reconciling them is manual work, and the resulting figures are difficult to rely on.
A small staff and a national mandate
Staff numbers do not increase with the workload. Backlogs accumulate over successive filing seasons and are rarely cleared.
Filing and payment take time
Filing often requires an in-person visit, paper forms, and time away from productive activities. Non-compliance is often a consequence of that effort rather than of intent.
Reasons administrations approach us.
Most enquiries follow a specific pressure rather than a general review. These four are the most common.
An implementation deadline set in law
The regime begins whether or not the system is ready. The rest of the program is scheduled backwards from that date.
The next exchange deadline
CARF reporting must be in place before the first exchange, alongside the CRS and FATCA cycles already in operation. [confirm the dates that apply to your jurisdiction]
Revenue growth without rate changes
Improving collection on existing taxes is often the only measure available.
A finding from an assessment
A TADAT or PEFA finding, or a lender program with a digitalization milestone attached to disbursement. [confirm wording]
If one of these applies, it is useful to state it at first contact. It affects what we would propose and the order of the phases.
Modernize tax administration and revenue collection.
Replace separate registers and manual handling with a platform that carries a taxpayer from registration through to collection and reporting. Automate the routine, keep the judgement with your officers, and give the administration a single account of every obligation.
- Supports all major tax types within a single integrated system.
- Supports secure online filing and payment through self-service portals for citizens, businesses, and tax agents.
- Provides reporting, analytics, and policy simulation capabilities.
Register
Register once and maintain a consistent taxpayer identity across all tax types.
File
Submitted online or captured at the counter, and validated on receipt.
Pay
Payment methods available locally, reconciled against the account.
Assess
Assessments are generated according to rules configured from national legislation.
Audit
Case selection on risk criteria, with the taxpayer history attached.
Collect
Arrears, instalments and enforcement tracked with ageing.
Report
Generate management reports and international exchange submissions from a single source of data.
Data is not re-entered between stages. Reporting at the end of the process therefore draws on the same records as the transactions that produced it.
All tax types in one compliant system
MTS brings every tax type into a single platform that reflects your national legislation. Rules are configured rather than coded, eligibility and liability are determined step-by-step, and the administration works from one unified record for each taxpayer.
Taxpayer, business and agent interactions
Citizens, businesses and tax agents use online portals to register, file, pay and check their position. The portal adapts to each profile and sets out the obligations that apply, which reduces service desk workload and shortens the time it takes to comply.
Full visibility, governance and compliance
MTS validates declarations and compares them with records held in permit, social security and third-party systems. Inconsistencies surface early, audit selection is documented, and management reporting draws on the same data as the transactions behind it.
What the system covers
- Compiles all tax types in one system: income tax, wage tax, corporate tax, turnover or value added tax, property tax, excise and licence based levies.
- Incorporates national legislation and internal procedures, guiding officers step by step through eligibility, liability and assessment.
- Registers a taxpayer once and identifies them across every tax type, with one current account and one history.
- Processes routine cases automatically and routes cases requiring judgement to officers.
- Supports online filing and payment through portals for citizens, businesses and tax agents, with local payment methods reconciled against the account.
- Manages arrears, instalment arrangements and enforcement in a single queue with clear ageing.
- Selects audit cases on configured risk criteria, with each selection explainable and auditable.
- Cross checks taxpayer data with permit, social security and employment records to monitor overall compliance.
- Prepares international exchange obligations, including FATCA, CRS, CbC, EOIR and CARF, alongside the Multi Data Exchange Solution.
- Analyzes trends through reporting and simulation, so policy changes can be modelled before they are enacted.
- Can be introduced for a single tax type and extended to others as budget and capacity allow.

Screens show the standard configuration. Forms, labels, workflows and languages are configured for each administration and its legislation.
How the system accounts for these conditions.
Many enterprise tax administration systems are designed for large jurisdictions with extensive IT resources, long implementation timelines, and significant organizational capacity. MTS is designed specifically for smaller administrations operating under different constraints.
Legislation held as configuration
Tax rules are configured rather than written into code. A change to a rate or a new regulation can be applied without a development cycle or a separate contract.
Maintained by the authority
After handover, authorized personnel maintain rates, thresholds, forms and workflows. Independence from the supplier is part of the delivery scope.

Continuity of ownership
Blyce has supported governments in the Caribbean and beyond since 1985, providing long-term continuity and sector expertise. A tax system generally outlasts the administration that commissions it, which makes supplier continuity a practical consideration.

Three island administrations consolidated onto one platform, alongside the introduction of a new tax regime.
Legacy data was cleaned and migrated, processes were redesigned across the three islands in parallel, and taxpayer portals were introduced. The implementation deadline was fixed in law, which set the program timeline.

Questions worth putting to any supplier of a tax administration system.
These criteria distinguish suppliers more reliably than a feature comparison. Our own answers are set out below, and the same questions apply to every supplier on a shortlist.
Is the law configured, or written into code?
Configured, not coded. Tax rules, rates, thresholds and filing obligations are set as configuration that reflects national legislation, rather than written into custom software. A rate change or a new regulation can be applied within days by authorized personnel, with no release cycle and no dependence on the supplier.
Who owns the data, and where is it hosted?
The revenue authority owns its data at all times. Hosting can be on premise in country, in a regional facility, or managed by Blyce as a hosted service, and the authority can move between these options later. Data ownership, residency and security terms are set out in the contract, so control stays with the authority.
What are the exit terms?
Exit terms are agreed before signature, not left until renewal. If the authority moves on, its data is returned in a standard, usable format on the terms fixed in the contract. This avoids vendor lock-in at the end of the engagement.
Is the price published?
Yes. Licence, maintenance and implementation fees, and the funding arrangements available to small states, are published and downloadable. Pricing is set out in full before any commitment, so the total cost of ownership is clear from the start. Fee structure
On what basis were the quoted results measured?
Every quoted result is attributable. For each figure, the case study states the institution, the baseline it was measured against, and the measurement method used, so the numbers can be verified.
Can references be contacted without the supplier present?
Yes. Blyce provides contact details for reference clients at other revenue authorities, so the conversation takes place directly and without us present. Peer references are often the most reliable guide to how the system performs in practice.
Questions raised during procurement.
What does an implementation involve, and how long does it take?
Six phases: discovery, configuration against national legislation, data migration, parallel operation, transition and handover. In the Caribbean Netherlands this ran to six months across three islands, because the commencement date was set in law. Most programs are planned over a longer period. The authority provides a named program owner, policy decisions on the edge cases in its legislation, and officer time for testing, agreed in advance.
