tax income and chargeable gains tax

hello, sir I am struggling with this question. Can I get some idea for this question?

I was employed until 31st December 2020. The P45 I received from this job had salary of £18,750 with tax paid of £1,875. From 1st January I have been self-employed, my first accounts to 31st December 2021 had taxable profits of £21,000. I have also owned another company for many years, from this I have dividend income of £7,000 and I have interest received from my savings of £1,400 and from my ISA of £700.

I also sold some of my personal assets and received the following:

1. Six acres of land for £61,000. This represents part of a 10 acre plot I purchased in 1993 for £39,000. The remaining four acres are valued at £45,000.

2. £100,000 for the house I used to live in. I bought the house in February 2016 for £45,000. I lived in the house for 8 months before moving overseas to work for 12 months, when I returned I moved in with my then girlfriend, now wife.

3. £75,000 for 50% shareholding in my business (which I started), I originally invested £5,000 for these shares.

4. £30,000 for a painting I acquired for £14,000

Please could you let me know the income tax and capital gains tax liability for the year.
