About this tool
Claim what you're owed for working from home.
Most self-employed people and company directors under-claim on home office costs, either because the rules feel fiddly or because nobody's sat down and worked it out for them. This calculator does the sums in under two minutes so you can see the tax you could reasonably save before your next return.
Who it's for
UK sole traders, freelancers, and limited company directors who work from home at least part of the week.
What you'll need
A rough idea of your rooms, hours worked from home, and your household running costs (rent or mortgage interest, utilities, council tax, broadband).
What you'll get
An estimate of the allowable expense you can claim and the tax that would save you, based on a basic-rate taxpayer.
What tax year do you want to calculate this for?
Estimates only. Assumes a basic-rate taxpayer (20% Income Tax + 9% NI). For personalised advice, speak to Calibra.
