Calculating Your Tax Relief

Basic Rate Taxpayer (20%)

CalculationExample
You want to contribute£200/month
Relief at source:
You actually pay£160
HMRC adds£40
Total in pension£200
Net pay:
You pay from gross£200
Tax saving (automatic)£40
What it “costs” you£160

Higher Rate Taxpayer (40%)

CalculationExample
Contribution£500/month
Basic relief (automatic)£125 (20%)
Total in pension£625

Total in pension£1,250
Higher rate relief (claim)£250 (extra 20%)
