Understanding Ghana’s new Integrated Tax Administration System (ITAS): A simple guide to ITAS — what it is, why it matters, and what it means for every Ghanaian taxpayer
Every day, thousands of Ghanaians benefit from the roads we use, the hospitals we visit, the schools our children attend, and the public services that keep our communities running. Much of this infrastructure and these services are funded through tax revenue. Yet, for many taxpayers, the process of paying taxes has not always matched the smooth, modern services those taxes help provide.
Consider Akosua, a fabric trader at Makola Market. She wants to do the right thing: register her business, keep accurate records, and set aside money to meet her tax obligations. However, when it is time to file, she finds herself moving between different counters and systems: one process for Value Added Tax (VAT), another for withholding tax obligations. Each process is disconnected from the next, with no single place to view what she owes or what she has already paid.
Akosua’s experience reflects a wider challenge the Ghana Revenue Authority (GRA) has identified and is addressing through the introduction of a new digital platform: the Integrated Tax Administration System (ITAS).
What is ITAS?
In simple terms, ITAS is a single digital platform that brings together the core functions of tax administration, including taxpayer registration, filing of returns, payment processing, compliance management, audit, enforcement, and reporting.
![IT must be one of the most difficult – and exasperating – tasks in the world to be the President of a nation like Ghana. For you may travel all over4 the world, talking to the leaders of “the developed nations”, to try persuade them that the pandemic that is afflicting the world, Covid-19 (with its variants) is a truly global destroyer and thatnowhere is safe from it, until everywhere is safe. You may deploy your most eloquent language to point out that although, the scientists of the “developed countries” have managed to manufacture a vaccine that has been seen to work against the pandemic, the politicians of the “developed countries” are, contrary to undertakings they have made to the World Health Organisation (WHO) hoarding the vaccine in their countries. Reports suggest that whereas the governments of the “developed countries” are targeting 100 percent of their populace for vaccination, and getting closer to their objective every day, less than 10% of the populace of the developing countries have so far been vaccinated, as a result of a lack of vaccines. Is this fair? you ask. Air travel (you continue) has made international contacts extremely easy. And since the Covid-19 virus and its latest variant (Omicron) in particOman Ghana versus Covid-19 08 www.ghanaiantimes.com.gh GHANAIAN Times Features TUESDAY, DECEMBER 21, 2021ular, are very transmissible. So it is in everyone's educated self-interest to see that all people on the planet are fully vaccinated. As a result of your Government's efforts, you hear that plenty of vaccines have arrived in your country and you are emboldened to announce that your Government will soon be able to vaccinate its entire adult population. Then, you get the shock of your life: an intelligence report tells you that some mischievous people are spreading the fake news that if a person allows himself or herself to be vaccinated, the “vaccine will make that person vote for your governing NPP whether he/she wants to do so or not!” WHAAAAT! How does one counter such fake news? If the Government say it is not true, the conspiracy theorists shoot back, “And are you so naïve as to expect them to admit that the vaccine will make you vote for the NPP?” Wow! Are people so wicked that despite the gains that the world has already made through vaccination (such as the elimination of small pox from the world and the near-extinction of polio and yellow fever) they try to dissuade others from taking advantage of anti-Covid vaccination? Especially since people who are clever enough to invent such fake news must know of the horrible pain that Covid-19 subjects people to, before it finally kills them? What makes the anti-Covid vaccination story doubly awful is that its seeds are sown on pre-fertilised ground. In the past, some wicked scientists in the developed countries have allowed themselves to be used by their [usually racist] governments to administer harmful vaccines and other medications to people, using the lie that such interventions can save them from certain disease. One of the most devastating such deceptions occurred in the United States in 1932. Below is the horrible story as told on the OFFICIAL website of the US CENTRES FOR DISEASE CONTROL [CDC]: https://www.cdc.gov/tuskegee/timeline.htm QUOTE: THE U.S. PUBLIC HEALTH SERVICE SYPHILIS STUDY AT TUSKEGEE In 1932, the USPHS, [US Public Health Service] working with the Tuskegee Institute, began a study to record the natural history of syphillis. It was originally called the “Tuskegee Study of Untreated Syphillis in the Negro Male” (sic) [now referred to as the “USPHS Syphilis Study at Tuskegee”]. The study initially involved 600 Black men — 399 with syphillis, 201 who did not have the disease. Participants’ informed consent was not collected. Researchers told the men they were being treated for “bad blood,” a local term used to describe several ailments, including syphillis, anaemia, and fatigue. In exchange for taking part in the study, the men received free medical exams, free meals, and burial insurance (sic)! By 1943, penicillin was the treatment of choice for syphilis and becoming widely available, but the participants in the study were not offered treatment. In 1972, an Associated Press story about the study was published. As a result, the Assistant Secretary for Health and Scientific Affairs appointed an Ad Hoc Advisory Panel to review the study. The advisory panel concluded that the study was “ethically unjustified”; that is, the “results [were] disproportionately meagre, compared with known risks to [the] human subjects involved.” In March 1973, the panel advised the Secretary of the Department of Health, Education, and Welfare to instruct the USPHS to provide all necessary medical care for the survivors of the study. The Tuskegee Health Benefit Programme was established to provide these services and in 1975, participants’ wives, widows and children were added to the program. In 1995, the program was expanded to include health, as well as medical, benefits. The last study participant died in January 2004. The last widow receiving THBP benefits died in January 2009. ... I973, a class-action lawsuit was filed on behalf of the study participants and their families, resulting in a $10 million, out-of-court settlement in 1974. On May 16, 1997, President Bill Clinton issued a formal Presidential Apology [over the study.] UNQUOTE In Ghana, the fake news that the anti-Covid vaccine would make people “vote for the NPP” has already begun to cause disagreements in some households. A family known to me has had to dismiss its house-help because she obstinately refused to take the jab. To illustrate the way the way the political message contained in the fake news has been camouflaged, I offer a version of the last conversation between the head of the household and the house-help: BOSS: Hey, “A”, you are very lucky! Instead of you going around to look for the vaccinators, they are coming to our estate! HOUSE-HELP: They are coming here? B: Yes! H: But Boss, I told you that my brother took the jab and had to be admitted into hospital. B: It doesn't mean that you too will become ill if you get the jab. It affects different people in different ways. Look, as you know, I have had all my own jabs and I have never been ill – as you know! H: But Boss, if you have taken all your jabs, then you are PROTECTED, are you not? B: Yes, I am. H: In that case, even if I become infected because I have not taken the jab, I cannot transmit the disease to you and YOU will be all right? B: I can't say that! Because, as I have explained to you, the pandemic can affect different people in different ways. H: Then the jab is useless? B: Listen, I can't take any risks with such a dangerous disease. Either you take it or you leave, I am sorry. I cannot allow you to expose me and my family to the risk of catching Covid. As I reported earlier, the House-help chose to leave. Both her Boss and I are convinced that it wasn't mere logicthat made her decide not to take the jab. She was probably under the influence of a church/cult. Or political propaganda! • Omicron cases at Kotoka International Airport are amongst the unvaccinated](https://ghanaiantimes.com.gh/wp-content/uploads/2021/12/GT-8.pdf-Adobe-Acrobat-Pro-DC-4-220x150.jpg)
Think of it like the difference between keeping your money in several different accounts at several different banks, each with its own passbook and its own queue, versus having one account that shows you everything at a glance. That is the shift ITAS represents for tax administration in Ghana.
Historically, tax administration within GRA’s Domestic Tax Revenue Division (DTRD) relied on manual processes and several standalone legacy systems. Although these systems served their purpose for many years, they also created fragmented taxpayer data, limited integration, duplicated processes, and operational inefficiencies. These challenges affected both GRA’s ability to make timely, informed decisions and taxpayers’ experience in meeting their obligations. ITAS replaces this fragmented domestic tax administration landscape with one modern, scalable platform and gives every taxpayer a single profile for managing their tax affairs.
A journey years in the making
ITAS is not a sudden idea. It is the product of a long and deliberate process shaped by GRA’s broader digital transformation agenda and its strategic ambition to become a world-class revenue administration. A key objective of this agenda is to support Ghana’s goal of increasing the tax-to-GDP ratio to 20 per cent.
The journey began in 2019, when GRA initiated the procurement of two separate systems: one for general tax administration and another dedicated to VAT. Vendors submitted proposals for both systems, and the required approvals were secured from the Public Procurement Authority. However, during the evaluation stage, a recommendation emerged that changed the course of the project: instead of building two separate systems, GRA should adopt the global best practice of implementing a single, comprehensive platform covering all tax types.
GRA accepted the recommendation. The two original tenders were cancelled, and the Authority partnered with the International Monetary Fund (IMF) to jointly develop the requirements for one unified system. Together, GRA and the IMF produced comprehensive Terms of Reference for a Commercial-Off-The-Shelf ITAS solution, which was reviewed and approved by GRA’s Top Management. The proposed system provided for online filing and payment, paperless and fully automated processes, multi-channel service delivery, real-time data processing, data-driven decision-making, and risk-based compliance management based on taxpayers’ compliance history.
This approach builds on a model GRA has already proven elsewhere in the Authority. The Customs Division operates the Integrated Customs Management System (ICUMS), which streamlines Customs processes, reduces costs, and improves trade facilitation. In a similar way, ITAS is DTRD’s end-to-end system for domestic tax administration, designed to replace fragmented, manual processes with one integrated platform. As ITAS matures, GRA envisions closer integration between domestic tax and customs operations, bringing the two systems into greater alignment over time.
Why ITAS matters
ITAS matters because an automated, integrated tax system strengthens how a country collects revenue, serves taxpayers, and manages compliance.
GRA’s broader digitisation drive has been building toward this moment. This includes the modernisation of its technology infrastructure and data centre, the adoption of Microsoft 365 productivity tools across its workforce, and the move toward a Cashless GRA through Ghana.gov. Cashless goes beyond Ghana.gov. ITAS is the centrepiece of this transformation: a system designed to help GRA support the objective of achieving a 20 per cent tax-to-GDP ratio, a benchmark that reflects a tax administration operating at full strength.
Every gap an outdated or disconnected system leaves behind is a gap in revenue collection — and that gap has real costs. It can mean slower services for taxpayers, missed opportunities to detect fraud or non-compliance, and less money available for the schools, hospitals, and infrastructure projects that depend on government revenue. An integrated system closes that gap. It gives GRA real-time visibility into compliance across the country, supports better risk assessment and more targeted enforcement, and reduces the manual processes that can introduce errors or delayed decisions.
ITAS is also designed to be taxpayer-centric, giving every business and individual the ability to file, pay, and track their obligations digitally through web portals, mobile applications, and other self-service channels without needing to visit a GRA office in person for every transaction. This reduces the time taxpayers spend complying with their obligations and makes meeting them easier than avoiding them.
How ITAS works
ITAS is built around a set of core features agreed jointly by GRA and the IMF, each addressing a specific weakness in the old way of doing things.
Taxpayer-centred, self-service design. ITAS enables taxpayers to file returns and make payments electronically, access their tax information through web portals and mobile platforms, and reduce reliance on manual paperwork and in-person visits.
Paperless and fully automated processes. By removing manual steps wherever possible, ITAS reduces the risk of error, speeds up processing, and gives GRA timely, accurate data to support its decisions.
Multi-channel service delivery. Taxpayers are not limited to a single way of interacting with GRA. ITAS supports multiple digital channels, so taxpayers can choose what works best for them.
Real-time data processing. Transactions are processed and analyzed as they happen, rather than in batches after the fact, enabling faster, better-informed decision-making.
Data-driven decision-making. ITAS allows GRA to analyse patterns across the system and make more informed choices about tax policy, risk, and enforcement priorities.
Risk-based compliance management. Rather than treating every taxpayer the same, ITAS segments taxpayers according to their risk profile and compliance history, allowing GRA to focus enforcement attention where it is genuinely needed, while reducing disruption for compliant taxpayers.
Looking ahead, a fully implemented ITAS is expected to integrate with the National Identification Authority for individual registration and the Office of the Registrar of Companies (ORC) for the registration of companies and organisations. It will also support core functions such as returns processing, taxpayer accounting, revenue accounting, refunds, case management, audit, objections, and appeals.
Plans are also in place to eventually connect ITAS with GRA’s other digital initiatives, including E-VAT, E-Commerce, Stamp Duty, and a central data warehouse. Over time, these connections will help bring the different strands of Ghana’s tax administration into a single, coherent picture.
Where things stand
ITAS is being rolled out in carefully managed phases, beginning with a pilot involving selected taxpayers and GRA offices.
The pilot phase commenced on April 1, 2026 at the Kaneshie Taxpayer Service Centre. Selected taxpayers from the Large Taxpayer Office were later onboarded onto the system. The current phase covers the filing and payment of four tax types: Pay As You Earn (PAYE), Value Added Tax (VAT), VAT Withholding, and Withholding VAT.
This phased approach is deliberate. Rather than moving the entire country onto a new system overnight, GRA is testing, learning, and refining ITAS with a defined group of taxpayers and tax types before expanding further. This carefully staged rollout, similar in discipline to the implementation of ICUMS, will help ensure that ITAS remains a stable and effective system for domestic tax administration.
What this means for you
If you are a taxpayer currently within the pilot’s scope — for example, at the Kaneshie Taxpayer Service Centre or as part of the Large Taxpayer Office — ITAS already means a more modern, self-service way of meeting your tax obligations.
If you are not yet part of the pilot, ITAS is still relevant to you. As the rollout expands, more tax types and more taxpayers will be brought onto the platform. The system is designed so that every taxpayer in Ghana can eventually manage their tax affairs through one unified system, rather than through the fragmented processes of the past.
It is worth noting that ITAS is a tool for administering tax more efficiently. It is not a mechanism for introducing new taxes. What it changes is how your existing obligations are filed, paid, and tracked, not what you owe.
How to prepare
You do not need to wait for the full rollout to start preparing. Taxpayers can take the following practical steps now:
- Make sure your taxpayer registration details with GRA are accurate and complete.
- Familiarise yourself with GRA’s existing digital channels, as these form the foundation on which ITAS builds. – All taxpayers file on GITMIS currently
- If you fall within one of the tax types currently covered by the pilot — PAYE, VAT, VAT Withholding, or Withholding VAT — take time to understand the new filing and payment process.
- Contact your nearest Taxpayer Service Centre for assistance where needed.
- Refer to the ITAS User Manual on the Authority’s website and tutorial videos on the GRA YouTube channel for additional guidance.
The success of ITAS will depend on the collective support, adaptability, and commitment of both GRA staff and taxpayers as the Authority transitions into a fully digital tax environment. A system designed to make compliance easier will deliver its full value only when taxpayers actively engage with it.
Ultimately, taxation is not simply an obligation handed down from above. It is a shared mechanism through which a country builds its future. ITAS represents a significant milestone in GRA’s transformation journey and a meaningful step toward a more efficient, transparent, and taxpayer-centred tax administration system for every Ghanaian.
