Your data stays with you. These tools run as JavaScript in your own browser. Nothing you paste or type is sent to us or stored, so you can use real class lists, bank lines and listings. The tax calculators give estimates for education, not tax advice.
For teachers
Rubric checker
Paste a rubric from ChatGPT, Google Docs, Sheets or Word. It flags judgement words like "good" with nothing to see, levels that differ only by "some" and "most", rows that mark neatness or effort instead of learning, and too many or too few levels.
Parents' evening notes builder
One line per student (initials, strength, next step, home step) becomes a timed slot list, a 5-part script per student, a follow-up message and a printable sheet. It flags "try harder"-style targets, praise with no example, full names and sensitive details.
Sub plan builder
Class details plus one line per block (time, task, materials, what to collect) become a one-page sub plan or cover work sheet to print. It flags tasks that need your login, tech with no paper fallback, new content, vague tasks, nothing to collect, and student details that don't belong on the desk.
For trades
Quote maker and checker
Type your scope lines and prices and pick exclusions for your trade. It writes a full quote or estimate with payment terms, adds up the VAT, adds the homeowner cancellation wording when it's needed, and flags vague words like "etc." and "as required".
Late payment interest calculator
Enter an unpaid invoice and the date it was due. It works out UK statutory interest (8% plus the right Bank Rate) and the £40, £70 or £100 compensation for business customers, or the 8% court-claim figure for homeowners, and writes out the sums to paste into a final reminder.
For bookkeepers
Records chase planner
Pick the deadline and your prep time and get a date for each chaser, moved off weekends and the Christmas and New Year bank holidays, as calendar reminders.
Making Tax Digital start-date checker
Enter a client's self-employment and property income for each year and see when MTD for Income Tax starts for them and their next deadline.
Client query-list builder
Paste uncategorised bank lines from Xero, QuickBooks, FreeAgent, Sage or a CSV and get a numbered client message, a WhatsApp version and notes for the accountant.
Year-end questionnaire builder
Tick what applies to the client and get a tailored questionnaire, a document checklist and a cover email, ready to copy or download.
Engagement letter schedule builder
Tick the services you've agreed and get a schedule for each (scope, volume, client duties, exclusions), a fee table with totals, the scope-creep clauses and a cover email.
Month-end close checklist builder
Pick the month and the client's set-up and get every close task in order, dated on working days with bank holidays skipped, plus the payroll and VAT or sales tax deadlines that follow. Downloads for Excel or Google Sheets.
Bank reconciliation checker
Enter the statement and book balances and paste the items on one side only. Get the reconciliation statement, any unexplained difference with its likely cause (one item, a reversed entry, swapped digits), stale-item warnings, and a download for Excel or Google Sheets.
For real estate agents
For online sellers (UK)
These calculators are on our sister site, sellertaxcalculator.co.uk.
Seller fee and side-hustle tax calculator
Work out your Vinted, eBay, Etsy, Depop or Facebook Marketplace fees, whether the £1,000 trading allowance covers you, and roughly what tax you'd owe.
Payments on account calculator
See why the first January bill can be one and a half times your tax, and what you'll pay on 31 January and 31 July.
Pay late or spread it? calculator
Compare the interest and penalties of paying a Self Assessment bill late with an HMRC payment plan (Time to Pay).
Which tax years need putting right?
