People havent really given you pukka advice Scoobz
Yes you do need to declare it as an income - I think it is LP on your tax form.If you dont fill out a tax form you will need to as soon as you let.
Your rental income is 500 a month or 6000 a yr
against that you can chaarge well advertised expenses of running.
Legal fees, repairs but not improvements, hse insurance, maintaianece such as gas maintenance.
AND that part of your mortgage which is the interest element.
NOT the capital repayment part. Lucky at the end of every year you get a statement from your mortgage firm telling you which part is which.
So effectively if you have an interest only mortgage of 500 a month then you wont pay anything
otherwise you wil have to keep accounts..... which is not really a pain.
and remember to keep every receipt.
if you make a whacking great loss, then your tax bill is 0 and you cant carry over the loss to your earned income. Pity but there it is
I am not sure if you can carry it over from one year to the next I think the answer is no
If you make a profit - then you pay tax at the marginal rate, so if you are paying 40% you pay at 40% and if at 20% then 20% up to 31k as has been explained elsewhere and 40% the excess.
easy I dont know why more people dont do it
From t he figures you have given you can pay the rent tax on your employed PAYE income.
