What to check
ℹ Reduced allowance. Your tax-free allowance (£12,560) is below the standard £12,570. That's usually company benefits (a car, medical cover) or an underpayment being collected. Your P2 coding notice shows the make-up — if a benefit has ended, tell HMRC so your code goes back up.
ℹ About £2/yr more tax than the standard code. At £35,000, this code takes roughly £0 a month more than 1257L would. Expected if you have benefits or an underpayment; if you don't, query it.
