£1.4 billion in pension tax relief goes unclaimed every year in the UK.
Most of it belongs to higher and additional-rate taxpayers who either don't know they're owed it, or find the process too complicated to start. Potly exists to change that.
Who's behind Potly?
Founded by Abi Dosumu
Potly was founded by Abi Dosumu, a qualified UK finance professional with over 10 years' experience in the field. After repeatedly seeing higher and additional-rate taxpayers either unaware they were owed pension tax relief — or unsure how to claim it correctly — she built Potly to make the process clearer and the calculations more accurate.
Today, Potly is supported by a qualified team focused on helping people understand their pension tax relief position and prepare HMRC-ready claim packs.
Built for taxpayers
Potly was created to make pension tax relief clearer and easier to claim — combining a calculator built to HMRC's actual rules with a fixed-fee documentation service. We don't take a percentage of your refund and we don't act on your behalf with HMRC. You stay in control of your claim.

What's different about our approach
Most online pension tax relief calculators give you a quick estimate based on your contribution and tax band — and stop there. They don't handle carry forward of unused allowance, annual allowance tapering, Scottish tax bands, or claims spanning multiple tax years.
Potly's calculator was built to handle these properly, so the estimate you see reflects the actual HMRC rules — not a simplified approximation.
Carry forward of unused allowance
Annual allowance tapering
Scottish tax bands
Claims spanning multiple tax years
Why we built it now
With income tax thresholds frozen until April 2031, more people are being pulled into higher tax bands every year — and more pension tax relief is going unclaimed as a result.
Most of the time it comes down to the same reasons:
The rules aren't clearly explained — parts of the relief are automatic, while others have to be claimed separately
Many people don't realise they need to do anything at all
HMRC processes can feel intimidating or unclear
