Wife has always had low income so her SA Returns transferred Marriage Allowance to Husband (He is not a client). So each claim has been made AFTER the end of each tax year.
Wife's estimated 2016/17 tax return went in last minute in late January 2018 with a claim as ususal to transfer marriage allowance to husband.
Her 2016/17 accounts have now been completed with a big jump in income (not higher rate). So she now want to stop the Marriage Allowance transfer to husband for 2016/17.
If I now revise wife's 2016/17 tax return with no reference to Marriage Allowance transfer at all, what will happen bearing in mind the original estimated 2016/17 tax return made a claim to transfer to husband. Will that revision reverse the claim made on the original estimated 2016/17 tax return.
Or has the horse bolted?
