Do landlords pay National Insurance on rental income?

Do landlords pay National Insurance on rental income? Usually not. In 2026-27, ordinary rental profit is charged Income Tax but no National Insurance. Only a letting business that is a trade, such as a bed and breakfast, pays Class 4. Some landlords can pay voluntary contributions. No, not on ordinary rental profit. Class 4 is charged on profits from a trade, profession or vocation. Rent from letting property is property income, so it is taxed but not charged to Class 4. No. HMRC's manual says most landlords do only what is normal for a landlord, which is not enough to count as self-employed for National Insurance, so they cannot pay Class 2 voluntarily. They may be able to pay Class 3 instead. Class 2 is £3.65 a week and Class 3 is £18.40 a week. Class 2 is only open to landlords whose letting counts as being gainfully employed.
