I have paid a lump sum into an AVC this last 2 years, mainly to offset some tax payable on a rental property but had wanted to start some anyway, so a double benefit of building a better pension while reducing a tax liability seemed logical. If I was to do this regularly through payroll instead of a lump sum, does it make any difference to anything? I asked payroll at work but was left confused hence my asking here. I understand this may be more a tax question than a pensions one, so I may be in the wrong forum.
