Built for how UK tax actually works
Most spreadsheet templates are generic, US-focused, or use a flat 25% tax estimate. Solofold is different.
Progressive tax engine
Real current-year UK tax bands — 20%, 40%, 45% income tax plus Class 4 NIC. Not a flat percentage guess that costs you money.
HMRC-aligned categories
Every expense category matches what HMRC asks for on your SA103S or SA105 return. No US categories, no guesswork.
Accountant-ready output
The Year-End Pack tab produces a summary your accountant can use directly. Less sorting time for them means lower fees for you.
MTD preparation layer
Prepares the exact numbers your Making Tax Digital software will ask for. Honest about what it is and isn't.
Payments on Account
Surfaces the January surprise months in advance. If your tax bill was £1,000+ last year, you need to know what's coming.
Complete documentation
Every product includes a User Manual, Walkthrough Guide, Quick Start Guide, and example file with a full year of sample data.
