For anyone self-employed who has to do a tax return at the end of the year, it would be great to create a pot which does the following:
When you create the tax savings pot, you enter your important tax details (e.g. whether or not you have a student loan).
Every time you get paid for a job you enter that amount of money you earned into the tax pot.
The pot then calculates the tax, national insurance, student loan etc. owed on that earnt amount and transfers it from your main account into the tax pot.
The pot also keeps a running tally of how much you’ve earnt, changes tax brackets accordingly as you earn, and factors the tax free allowance into its calculations.
That way, every time you get a payment from an invoice, you’re saving the correct amount of tax gradually - something I know a lot of self employed people struggle doing.
