The bill is over £1,000, so payments on account apply: £4,215.90 on 31 January and £4,215.90 on 31 July towards next year. In your first year of trading the January payment is the whole year's £8,431.80 plus the first payment on account, £12,647.70 in one go. More in the payments on account guide.
As a limited company instead
Paying yourself £12,570 salary and the rest as dividends, a company with the same £45,000 profit would leave you £35,247.32: £1,320.88 less than as a sole trader, after £5,945.96 corporation tax and £2,671.22 dividend tax. Try other options in the limited company calculator.
