Who is behind MySums
MySums is built and personally maintained by Eman Munir, a Chartered Certified Accountant (ACCA). I am not a large company with a content team. I am one accountant who got tired of watching people either guess at these numbers or pay for a conversation they did not need, so I built the tools I wished existed.
Every calculator on this site is mine from start to finish. I write the logic, work through the examples by hand before they go live, and keep an eye on the rules so the figures stay right as tax years change. If something on this site is wrong, that is on me to fix, and I would genuinely rather you told me than quietly stopped trusting the site.
You can also view my LinkedIn profile for an external professional profile connected to the author and reviewer named across this website.
MySums has a second co-founder, Shahzaib Nadeem, who built the site and looks after the technical side and how people find it. He does not write or review any of the calculations. The numbers, the worked examples and the sources are entirely my responsibility.
My background
I qualified as an Association of Chartered Certified Accountants (ACCA) member, which means my day to day work is governed by the same standards of accuracy and professional conduct that apply to accountants generally. I built MySums alongside that work because I kept running into the same pattern: someone needed a quick, correct answer to a tax or pay question, and the only options online were either a vague rule of thumb or a paid consultation for something that is really just arithmetic once you know the rules.
I will be adding more detail here about my background and experience soon. In the meantime, if you want to check anything about who is behind this site, get in touch and I am happy to answer directly.
How I keep the numbers right
Every figure on MySums is sourced from HMRC, gov.uk or the relevant national tax authority (gov.wales for Wales, revenue.scot for Scotland), never copied from a secondary summary. I check each calculator's logic the way I would check a client's numbers, and I revisit every page whenever a tax year, Budget or rate change affects it, not just when the page was first written. The full detail of how that process works is on the methodology page.
What MySums is not
MySums gives general, illustrative guidance. It is not personalised financial or tax advice, and it does not replace a conversation with a regulated adviser or accountant when a decision genuinely matters, such as a large pension contribution or a property purchase. Where a calculator sits close to that line, the page says so plainly.
The business behind MySums
MySums is run as a UK-based sole trader business, co-founded by Eman Munir, ACCA and Shahzaib Nadeem. It is independent: it is not owned by, funded by or affiliated with any bank, broker, pension provider, accountancy firm or price-comparison site, and no third party has any say in what the calculators show.
The site makes no money from your results. There are no referral fees, no lead generation and no paid placements. Running costs are covered by contextual advertising that has no bearing on the figures. If that ever changes, this page will say so before it does.
