Features
Tally Up replaces spreadsheets, shoeboxes, and guesswork with a simple tool built for Manx sole traders. Track income, log expenses, snap receipts, see a live Isle of Man tax estimate, and send invoices, all in one place.
The Isle of Man has its own tax system, separate from the UK. The IoM tax year runs from 6 April to 5 April, tax returns are filed with the Assessor of Income Tax (not HMRC), and income tax bands and National Insurance rates are set by the Isle of Man Treasury. Tally Up is built around these rules from the ground up. Every feature below is designed with Manx sole traders in mind: from receipt capture that categorises expenses for your IoM tax return, to a live tax estimate that uses the correct local rates.
Lost Receipts → Snap photos anywhere
Snap a photo of receipts and invoices as soon as you get them. Tally Up stores them securely and links them to your entries, so you'll never lose important paperwork again. A taxi driver logging a fuel receipt at the rank, a plumber photographing a parts invoice on site, it's instantly categorised and ready for your tax return. Our AI reads the receipt details automatically, extracting amounts, dates, VAT, and merchant names so you don't have to type anything by hand. Every receipt is stored safely in the cloud and attached to the right expense entry, ready for when your accountant asks for it.
Surprise Tax Bills → Know what to save
Tally Up shows you a running estimate of how much to set aside for tax and National Insurance based on what you've entered so far. No more nasty surprises or last-minute panic when the tax bill arrives. A freelance designer earning £45,000 sees an estimated IoM income tax and NI figure based on their records to date, so they know roughly what to set aside each month. Your dashboard updates as you log income, and Tally Up flags when you're likely to cross a threshold, like the higher rate income tax band or the VAT registration limit. Compare what-if scenarios to see how extra income or new expenses would affect your tax estimate before you commit.
Spreadsheet Hell → Simple tracking
Stop wrestling with Excel formulas and conditional formatting. Tally Up totals your income and expenses, tracks VAT, and keeps everything organised without you having to remember complex spreadsheet rules. Instead of maintaining separate sheets for income, expenses, and mileage, a self-employed electrician tracks everything in one place. Link expenses to clients, categorise them for your tax return, and let Tally Up handle the maths, including VAT if you're registered. Create customer estimates and convert them to invoices when the work is done, all without leaving Tally Up.
Tax Return Chaos → Download & done
When tax time comes around, Tally Up generates everything you or your accountant needs with just a few clicks. No more scrambling to find receipts or trying to remember what happened months ago. At the end of the IoM tax year (5 April), download your complete income and expense summary as CSV or HTML, with all your receipt images bundled in, ready to file with the Assessor of Income Tax or hand straight to your accountant. Your accountant can pick it up without any prior knowledge of Tally Up: the exports are clear, complete, and well-organised.
Foreign Software → Manx Business
Most sole trader software is built for other countries' tax systems: UK tax codes, HMRC deadlines, rates that don't apply here. Tally Up is designed specifically for Manx businesses, using Isle of Man income tax bands, Class 2 and Class 4 National Insurance rates, VAT thresholds, and local requirements. The IoM tax year runs 6 April to 5 April, your tax return goes to the Assessor of Income Tax, and the key deadline is 6 October. Tally Up knows all of this out of the box.
Stuck on one device → Works everywhere
Tally Up works on your phone, tablet, and computer. Your data syncs automatically, so you can snap receipts on your phone and review everything on your laptop at home. Start logging a receipt on your phone at the job site, review your tax estimate on your laptop that evening, everything stays in sync. There's no app to download. Tally Up is a web app that works in any modern browser, and you can install it to your home screen for quick access.
Silent Users → Shape Tally Up's Future

Every feature request is visible to the community, and you can see exactly where your suggestion sits in our development pipeline. We're a small team on the Isle of Man, and we listen.
