InForaPennyinForaPound

Hello there I wonder if you would clarify something (I have checked ALL of the guidance and help pages on HMRC and am none the wiser, hence this post): My wife has no paid employment, no state pension (not for a few years yet) and doesn't claim any benefits. This tax year she has taken a gross income from her private pension of £13,500.00 — which *includes* a tax-free amount of £2,750.00. She doesn't intend to draw any more income from her private pension this tax yer. How much may she earn in interest before having to pay income tax, please? (I find the £5,000.00 'starting rate' and the extra £1,000.00 scenarios confusing. I am just looking for as straight an answer as possible, please.)
