The process of changing the tax code is outlined under sections 40 and 41 of the Public Finance Management Act of 2012. Section 40 outlines the Submission and consideration of budget policy highlights and the Finance Bill in the National Assembly, and section 41 outlines the passing of the Finance Bill. They have been four major complaints about Kenya’s Tax Code;
The Mandatory Nature of Submission and Consideration of the Finance
Section 40 of the Public Finance Management Act (PFMA), 2012 requires that each financial year, the Cabinet Secretary shall, with the approval of the Cabinet, make a public pronouncement of the budget policy highlights and revenue-raising measures for the national government. The Cabinet Secretary shall take into account any regional or international agreements that Kenya has ratified, including the East African Community Treaty and where such agreements prescribe the date when the budget policy highlights and revenue-raising measures are to be pronounced, the Cabinet Secretary shall ensure that the measures are pronounced on the appointed date. Section 40 emphasizes the word shall concerning functions of the Cabinet Secretary under section 40 of the PFMA.
On the same date that the budget policy highlights and revenue-raising measures are pronounced, the Cabinet Secretary shall submit to Parliament the Finance Bill, setting out the revenue-raising measures for the national government, together with a policy statement expounding on those measures. Note the word used is shall, making it mandatory for Cabinet Secretary to submit to Parliament the Revenue Raising Measures. Section 41 of the PFMA requires that not later than ninety days after passing the Appropriation Bill, the National Assembly shall consider and approve the Finance Bill with or without amendments. The salient issue that stands out from the reading of Section 40 of the public finance is that the law makes it mandatory for the Cabinet Secretary in charge of the National Treasury to table finance bills for consideration once approved by Cabinet. The keyword used in this case is shall. According to the Merriam Webster Dictionary, the word “shall” is used in laws, regulations, or directives to express what is mandatory[4].
Key Policy Concerns
Making it mandatory for issuance of the Finance Bill annually presumes that only the widening of revenue-raising measures through the introduction of new tax measures will automatically increase the tax collections. That is not always true because of these major reasons.

Even if more revenue-raising measures are proposed in a weaker economy, the results would not boost growth in revenues.
Conclusion and Policy Recommendations
It is evident that the national tax code variation does not need to happen on an annual basis, but a medium-term review due to economic policy objectives, economic growth, tax buoyancy, and the Laffer effect. This could require amendments to the PFMA to make it conditional for submission of the Finance Bill and consideration by Parliament by changing the wording of the law to reflect the “may” scenario. This will allow the Cabinet Secretary in charge of the National Treasury to only table the Finance Bill where necessary.
