Should I use tax free to pay off mortgage?

fjh

I have within my SIPP more than sufficient within the tax free 'allowance' to pay off my mortgage of £44k which has a fixed rate that expires in August 2019.

My rationale - I pay £600 per month on mgte, - use £44k from tax free part of SIPP and then as I am in a new pension with my current employment to which a total of £590 per month is paid 'add' 1k per month which would 'cost' me £600 after tax relief into my pension which is currently 10k as soon as this pension gets to @29k or in 30 months my planned retirement date transfer to my SIPP.

QUESTION - does this make sense? would it be a 'good option' ? - I am currently net of charges 'earning' 2% ( partly due to 'smoothing' impact of Prudential fund which is a large % of my SIPP)

AFAICS that's exactly what you should do. As you approach the date for retiring you should stuff as much as possible into your pension fund (taking note not to exceed the annual allowance). If you currently a higher rate taxpayer won't be after you retire pushing the money through the pension washes away tax so when you come to drawdown your effective tax rate is only 15% (25% TFLS then 20% income tax). At the moment you are paying tax on the money used to repay your mortgage so are currently losing £400/month.
