One register for your IP
Each qualifying asset sits in one register, with the income it earned and what it cost to develop.The nexus fraction
Sumly works it out from what you spent on development, split by who did the work.The 80% deduction
Sumly takes 80% of each asset's qualifying profit as the deduction. At a fraction of 1.00, you pay an effective 3% on that profit.
Every asset, kept apart.
The law asks for separate records of income and spending for each qualifying asset. In Sumly that's a tag on the entries you already post, so there's no second spreadsheet.
- Register software and patents your company developed
- Each sale tagged to the asset that earned it
- Development costs tagged as you post them
The fraction, from what you spent.
The nexus fraction scales the deduction by how much of the development you did yourself or paid unrelated contractors to do. Sumly builds it from the costs you tag.
- Your own developers and unrelated contractors count in full
- Bought-in IP and related-company work lower it
- Build it all in-house and the fraction stays at 1.00
The deduction, with its workings.
Sumly applies the fraction to each asset's profit and works out the 80% deduction. The schedules set out each step for the tax return.
- A computation for each asset, every year
- Schedules ready for the tax return

Cyprus accounts ready
The chart of accounts already has accounts for capitalised development costs, software, patents and royalty income.Every figure traced
You can follow each figure back to the entries and documents that produced it.One fraction per asset
A company with three products can have three different fractions. Sumly calculates each one from that asset's own costs.Built year after year
The fraction counts spending over the asset's whole life. The totals carry on, so next year's claim starts where this one ended.Salaries count too
Your developers' salaries are development spend. Tag them to the asset they worked on, the same as a contractor's bill.Help with the application
