Our story

How HM Consultancy began

HM Consultancy began with a pattern. Again and again, people who were trying to do the right thing had a KRA PIN but had never been shown what they needed to file, or when. Most of the stress came from not knowing, not from the tax itself.

Its founder, Harriet Ndiritu, saw that pattern up close. Her career in tax and finance has spanned finance and business development, audit, accounts, bookkeeping and tax consultancy. That is where she learned how a client's records, their tax position and the advice they receive all depend on each other.

She then spent almost a year and seven months in taxpayer service, helping taxpayers with their questions. She met people who had registered for a PIN only to open a bank account or receive payment for a job, and who did not know they had to file returns. Others had missed out on penalty waivers and tax amnesty programmes.

Friends and family soon began calling her with their own tax questions, so she began offering free help, reviewing their accounts and making sure they were compliant. Over the years, that word-of-mouth support grew into a steady stream of referrals: filing returns, reviewing accounts, registering VAT obligations, registering for eTIMS and generating eTIMS invoices, and explaining obligations such as Monthly Rental Income (MRI).

In October 2026, she made it official and founded HM Consultancy, with Ian Waiyaki Githagui as co-founder. Alongside this, Harriet continues to work hands-on in finance, posting receipts and payments, keeping the books accurate, filing statutory deductions and returns, and presenting financial reports to the people who rely on them. So HM Consultancy sees tax from both sides: as people who have helped taxpayers, and as people who have to file on time and report clearly.

Today, HM Consultancy helps individuals and businesses review their finances, file accurate returns, set up eTIMS and stay in good standing with KRA. The goal is simple: to make sure you are tax compliant, hold your Tax Compliance Certificate, and never have to worry about tax again.

How we work

How we look after you

We explain first

You will always know what we are filing and why. If something is unclear, ask us. That is what we are here for.

We get it right

Every return is checked before we submit it, because your name is on it and ours is too.

We keep you ahead

We remind you before each deadline and let you know when the law changes, so you are never the last to hear.

Professional standards

What you can expect from an engagement

  • Scope and fee in writing

    We confirm what we will do and what it costs before we start, so you know where you stand.

  • Advice based on your facts

    We review your records first and recommend what suits your situation, not a one-size-fits-all answer.

  • Clear written findings

    You receive a summary of what we found, what we recommend and what happens next.

  • Confidential by default

    Your documents and financial information are used only for your tax matter.

  • Honest about risk

    We tell you where you are exposed and what could go wrong, including when the answer is not what you hoped for.

  • Lawful and transparent

    We help you reduce tax only through legitimate means, and we never take positions we would not stand behind with KRA.

HM Consultancy provides tax and compliance advisory services. Our guidance is based on Kenyan tax law as it stands on the date shown, and we never promise outcomes that KRA controls.
