TOOLS · 2026/27 EDITION
Spreadsheets built by a bookkeeping practice, for people doing it themselves
The same working tools we use with clients, tidied up for you to run on your own. Type in your numbers; the tax rules, HMRC rates and warnings are already built in. Works in Excel and Google Sheets.
Built by an IAB-supervised practice
Made by NDA Silva Ltd, a regulated bookkeeping and accounts practice — not a template mill. Rates checked against HMRC for 2026/27.
Every rate is editable
All thresholds and percentages sit on a Rates sheet. When HMRC changes something, you change one cell and every formula follows.
Sent straight to your inbox
Pay by card through Stripe. The file lands in your email within a couple of minutes, ready to open in Excel or Google Sheets.
Questions
Will it work in Google Sheets or Numbers?
Yes. The files are standard Excel workbooks with no macros. Upload to Google Drive and open with Sheets, or open in Numbers on a Mac — dropdowns, formulas and warnings all work. Excel gives the best experience for printing the dividend vouchers and minutes.
How do I get the file?
You pay by card on Stripe's secure checkout. Within a couple of minutes you'll get an email from accounts@ndasilva.co.uk with the file attached. Check your spam folder if it hasn't arrived after ten minutes, or reply to your Stripe receipt and we'll resend it.
Are the rates up to date?
Every file uses the 2026/27 tax year rates and thresholds (financial year 2026 for corporation tax), checked in September 2026. If HMRC changes anything mid-year you can update the Rates sheet yourself, and we'll release a 2027/28 edition next spring as a separate purchase.
Is this tax advice?
No. The tools do the arithmetic and flag the things that usually catch people out, using HMRC's published rules. They don't know your full circumstances. If you're unsure, ask an accountant — or ask us.
Can I get a refund?
Digital files can't be returned, so we don't offer refunds once the file has been sent. If something in the file is wrong or doesn't work for you, reply to the delivery email and we'll put it right.
Can I use it for more than one business?
Each purchase is licensed for one business (or one company). If you run several, or you're a bookkeeper wanting to use these with clients, email us for a multi-business licence.
Would rather someone did it for you?
These tools are what we use on the inside. If you'd prefer the bookkeeping, VAT, payroll and year-end handled for one monthly fee, take a look at our services.
