Free for partners # Put a working cross-border take-home calculator on your own site One script tag. It models UK limited companies, Portugal's IFICI regime, Spain's Beckham regime, all 50 US states and 41 other countries, in the browser, on your page, in your typography. There is no signup and no cost. [Get the snippet](#install) [See what it models](#how) ## Try it. This is the real thing, not a screenshot Everything below is the same widget your visitors would get. Change the corridor and the snippet updates with it.

If your CMS strips script tags, ask us and we will send an iframe version instead. ## Why you cannot easily build this yourself A take-home calculator is a solved problem for one country and one employment type. It stops being solved the moment a client has a company in one country and a life in another. ### The company and the person are taxed separately A UK limited company pays corporation tax before anything reaches the owner. What is left is what can be declared as a dividend, so the personal calculation depends on a number the company calculation produces. Getting this wrong is the most common error in free calculators. ### Expat regimes change the answer more than anything else On £120,000 through a UK company, a Portuguese resident on standard rates keeps £58,587. The same person under IFICI keeps £91,932. That single election is worth more than every other input on the form combined. ### The treaty sits in the middle Dividend withholding at source, the foreign tax credit in the country of residence, and whether social security is due in one country or both. Each pair of countries behaves differently. ### And then there are the 50 states US federal is the easy part. California, New York plus New York City, Texas at zero, and married filing jointly against single, all move the number materially. 44 countries modelled, each with its own bands, allowances and social security 51 US states and DC, with real bracket data rather than a flat rate 6 expat regimes including IFICI, NHR, Beckham and Cyprus non-dom 12KB compressed, loaded asynchronously, no dependencies and no iframe ## Installing it ### 1. Paste the snippet Put the container div where you want the calculator, and the script tag anywhere on the page. That is the whole integration. ### 2. Set your corridor If you specialise in one route, set `data-from` and `data-to` and your visitors land on the scenario that matters to them. A Portugal specialist should default to UK to Portugal. ### 3. Put your ref on it `data-ref` is your identifier. It rides on every link back to us, so anyone who arrives from your site is attributed to you. If we ever build a referral programme, this is the field it runs on. ### Every option - data-from and data-to : two-letter country codes, for example GB, PT, ES, AE, US - data-currency : GBP, EUR or USD - data-income : the figure it opens on - data-earn : ltd, self or emp - data-theme : light, dark or auto - data-accent : any CSS colour, to match your brand - data-title : your own heading for the widget - data-ref : your attribution identifier Multiple calculators on one page: give each container `data-takehome-calc` and its own attributes. Attributes on a container override the ones on the script tag. ## The terms, in full - It is free, with no usage limit and no key to manage. - Keep the "Powered by TakeHome" link visible. That is the entire price. - Use it on client-facing pages, in proposals, behind a login, wherever it helps. - We will tell you before anything about the calculation changes in a way that would change a number on your page. - Estimates are directional and the widget says so. It is not regulated tax advice and it does not replace you. ### What we get out of it People who want a number today become people who want a plan next month, and those people need an adviser. We would rather they meet you on your own page with a real answer in front of them than bounce off a thin calculator somewhere else. If you write about the tool or the regimes it models, link to the page you found most useful rather than to this one. That helps us more than the widget link does, and it gives your readers something to actually read. ## Questions Will it slow my site down? The script is about 12KB compressed and loads asynchronously, so it never blocks your page rendering. It makes no network request until a visitor changes an input. Does it collect data about my visitors? No personal data, no cookies, no fingerprinting and no advertising tags. The calculator sends the figures it needs to price a scenario, and an anonymous counter so we know how many sites have it installed. Nothing typed into it is stored against a person. Will it clash with my site's CSS? No. It renders inside a shadow root, so your styles cannot break it and its styles cannot leak into your page. Typography is the deliberate exception: it inherits your font so it reads as part of your site rather than a bolted-on box. How current are the tax rates? The 2025/2026 year, with each country's own caveats shown underneath the result. Six countries are modelled at lower confidence and the widget labels them as approximate rather than pretending otherwise. Can I remove the attribution link? Not on the free embed. If you need a white-label version for a client portal, email us and we will talk about it. Something looks wrong. Who do I tell? Email hello@takehome.ai with the inputs you used. If a number is wrong we want to know more than you do. ## Get it on your site today There is nothing to sign up for. Copy the snippet, paste it, done.
