As an employee, were you asked to work from home ? Did you get reminbursed from your company ?
If not, you may be entitled to claim tax relief on additional household expenses for examply extra heating and lighting.
How much can I claim
From 6 April 2020 - £6 per week or £26 per month
Prior to 6 April 2020 - £4 per week or £18 per month
Figures above are based on 20% basic rate of tax
So for someone who has been working from home since 6 April 2020 - 16 October 2020 (about a 28 week period), you could be entitled to:
£6 x 28 weeks = £168.00
How do I claim
Making a claim is easy, go to GOV.UK and search 'claim tax relief for your job expenses'.
It’s quick and secure, and those who are eligible will receive their full entitlement by an adjustment to their tax code.
It won't be enough to retire on but you might be able to have dinner out on the Taxman !!
