Help - overtime or time off in lieu

longwalks1

I need to find an additional 10 days holiday this year as Im travelling overseas for a family wedding.  I’ve got the option to take the time off unpaid at the end of the year.  

Or work overtime and have it paid to me as double time pay.
i can either work overtime now and save the extra money to cover my unpaid at Christmas.
Or, work overtime through the year for single pay and hours off in lieu.
im a higher rate tax payer.
is there an easy way to workout what’s best to do?  Im struggling with the tax etc and which option is better, financially

Are you close to £100k salary after allowable gross deductions like pension?

Getting double pay means you only need to do 5 days work to achieve your 10 days off. Working for time in lieu means needing to do the full extra 10 days. There may be a temporary change in tax due to the spike in earnings but this will come out in the wash when you are unpaid over Xmas
