Capital Gains Tax Query

MisterMotivated

Hello all.  I'm hoping someone on here can offer some advice.  I'm not normally a higher rate taxpayer, but will be selling a property that's eligible for a reasonable amount of Capital Gains Tax.  If I've understood it correctly, the CGT is applied at 18%, using up what's (estimated to be) left of my basic rate band, then 28% for anything over the higher rate threshold.  However, I'm unclear on how this will affect my overall tax situation, i.e. will I officially be a higher rate taxpayer for the year?  For example, will my Personal Savings Allowance drop to £500 and savings interest be taxed at 40%?  If my income ends up being higher than estimated (though still within basic rate band under normal circumstances), will any additional income be taxed at 40%, or will this be adjusted on my next Self Assessment so that the CGT is applied after the tax on all other income?

CGT comes after income tax so doesn't affect your income tax position.

But interest (or dividends) which are taxed at 0% can use part of your basic rate band so if you had say £1,000 interest taxed at 0% that could mean more of the Capital Gain is taxed at 28%.

Thank you, that helps clarify things.  I hadn't considered the PSA forming part of the basic rate band, so will keep that in mind.
