Some thoughts:
When did you start hosting? If it was after 1/October/2022 then you can't operate without a licence - Lets assume it was before 1/1022 in which case you need a licence by April 2023.
Just because the money is paid into your husbands account it does not mean he is liable for the tax. If you share the ownership of the property then you will both be liable for tax on 50% of the income minus expenses.
If your revenue is less than £7500 per year then there is no tax to pay if you qualify for the Governments rent a room scheme
The last two thoughts definitely apply in England - You need to check Scotland is the same.
