Embedded Files
TaxMateNG is a Nigerian tax and financial-record software application developed by EnochiGreen LLC.
It helps individuals, SMEs, HR teams, accountants, and tax professionals calculate supported Nigerian taxes, maintain organized financial records, and prepare data and reports for tax-related requirements.
TaxMateNG was built to make Nigerian tax and financial record-keeping simpler, more accurate, and more practical. As Nigeria's tax system evolves under the Nigeria Tax Act (NTA) 2025, effective from 2026, businesses and professionals face increasingly detailed calculations, reporting requirements, and digital filing processes. TaxMateNG brings many of these tasks together in one privacy-focused application.
Why We Built TaxMateNG
Keeping accurate financial records and calculating tax obligations can be time-consuming, particularly when businesses have to work across spreadsheets, manual calculations, and different reporting requirements.
TaxMateNG was built to reduce that complexity. The application helps users maintain their financial records, perform supported Nigerian tax calculations, and generate structured reports and files for supported tax and government platforms.
For businesses and professionals adapting to the 2026 tax environment, TaxMateNG provides practical tools for managing the work behind tax compliance without requiring users to rely entirely on manual computation and spreadsheet formatting.
Key Features
Financial Records and Tax Calculations
TaxMateNG combines financial record-keeping with tax calculation tools, helping users maintain organized records while working through supported Nigerian tax obligations.
The application supports workflows for areas including Personal Income Tax (PIT), Pay-As-You-Earn (PAYE), Corporate Income Tax (CIT), Value Added Tax (VAT), Withholding Tax (WHT), Capital Gains Tax, and Capital Allowance, where applicable.
Reporting and Export Tools
Tax-related information often needs to be presented in specific formats for submission or further processing. TaxMateNG helps reduce the manual work involved by generating supported outputs such as PDF reports, PAYE CSV files, and structured tax schedules.
Where applicable, these outputs can be used with supported systems and platforms, including Rev360 and TaxPro Max, helping users move from their financial records to structured reporting with less manual formatting.
An Error-Reduction Approach
Tax calculations can become complicated when multiple rules, thresholds, deductions, exemptions, and other conditions apply.
TaxMateNG's computation engine is designed and tested around applicable Nigerian tax rules, including provisions of the Nigeria Tax Act (NTA) 2025. The application is intended to reduce calculation and data-entry errors by applying supported rules consistently rather than requiring users to perform every calculation manually.
Offline Operation and Privacy
TaxMateNG is designed with a privacy-first, offline approach. Financial records, calculations, and file generation can be performed locally on the user's device rather than requiring financial data to be continuously transmitted to an external server.
This gives users greater control over their financial information while allowing them to work even when an internet connection is unavailable.
From Daily Records to Tax Preparation
TaxMateNG is designed for both everyday financial record-keeping and more advanced tax-related workflows.
SMEs can use it to organize operating expenses and maintain cleaner financial records throughout the year. HR teams and professionals can use its supported payroll and tax tools, while accountants and tax professionals can use its calculation and reporting features to manage more complex workflows.
Our Goal
Our goal is simple: to give Nigerians practical tools for keeping cleaner financial records, understanding their tax obligations, and handling tax-related work with greater confidence.
TaxMateNG is developed by EnochiGreen LLC and is available through its supported applications and platforms.

Engine Testing & Validation (NTA 2026 Compliance)
The TaxMateNG internal computation engine has undergone rigorous stress-testing to ensure absolute alignment with the Nigeria Tax Act (NTA) 2026 framework. Designed as an offline error-reduction layer for SMEs, HR managers, and tax professionals, both the PIT and CIT modules accurately handle complex regulatory logic to produce reliable, audit-ready compliance estimates.
Personal Income Tax (PIT) Engine Validation The Comprehensive PIT Validation Report confirms that TaxMateNG correctly implements Nigeria’s evolving 2026 individual tax framework.
Key Logic Validated: The engine successfully handles the complex merger of Taxable Capital Gains (CGT) into the progressive PIT bands (subject to the ₦150M/₦10M safe harbors), the elimination of the Consolidated Relief Allowance (CRA), the new ₦800,000 zero-tax threshold, and the statutory capped Rent Relief.
Testing Scope: The logic was thoroughly tested across high, medium, and low-income profiles. All calculations involving statutory deductions, multiple income sources, and progressive tax bands were verified for accuracy, with strict attention paid to edge cases and floating-point stability.
Result: The PIT module is highly robust and fully capable of structuring pristine payroll and personal ledgers under the new NTA mandates.
Corporate Income Tax (CIT) Module Validation The Corporate Export Module has been comprehensively validated to act as a definitive B2B compliance tool.
Key Logic Validated: All critical enterprise elements were rigorously tested. This includes the new SME Exemption dual thresholds (Turnover vs. Assets), sector-specific Capital Allowance (CA) restrictions, Unutilized Loss Carry-Forwards, and Corporate Capital Gains Tax (isolated cleanly at 30%).
METR Top-Up: Specific enhancements were validated for the Minimum Effective Tax Rate (METR) logic, ensuring configurable turnover thresholds for maximum auditability and legal flexibility.
Result: The CIT module reliably processes complex financial scenarios for general businesses and manufacturing entities, ensuring that generated PDF and CSV exports are mathematically sound and perfectly aligned with the 2026 tax regime.
