Why are yoy showing dates as 5th April to 4th April?
The tax year runs from the 6th April to 5th April.
You will have to pay 1.5 times the tax you owe for this tax period (9th Jan 15 - 4th Apr 15) by 31st Jan 16. The 0.5 times tax is tax "on account" for the tax year Apr15 - Apr 16, you would pay the other half of thus tax bill in July 16, although when you submit your 15 - 16 tax return the amount you owe would probably change.
It's not very likely that a business that only started in January would have to pay 1.5 times the tax for 2014-15 in January 2016, as most won't have a high enough tax liability.
That provision is much more likely to kick in in January 2017 based on the 2016 tax return, where the taxpayer will pay a full year's tax in one go AND the 50% on account for the following year
Yes it's a £1KWhat is the tax liability? Is there a threshold?
