National Insurance on Rental Income

Paying National Insurance on Rental Income

Treasury Considers New Tax for Landlords

The Treasury is reportedly reviewing proposals that could see UK landlords paying National Insurance Contributions (NICs) on rental profits for the first time. Currently, landlords pay Income Tax on rental income but do not pay NICs unless HMRC classifies the activity as trading. This potential change would significantly increase the tax burden for property investors.

In this article, we’ll explain what’s being discussed, how much it could cost landlords, and why moving property ownership into a limited company may become even more attractive.

How Landlords Are Taxed Now

Currently, landlords are subject to:

• Income Tax – paid on net rental profits after allowable expenses
• Capital Gains Tax – payable on property sales
• Stamp Duty Land Tax – with a surcharge on second properties

Most landlords do not pay NICs on rental profits. The proposed change would remove this exemption for most landlords.

What Could Change?

The Treasury is considering aligning landlords with self-employed workers, meaning rental profits could be subject to:

• Income Tax (as now)
• Class 4 NICs: 9% on profits between £12,570 and £50,270, 2% thereafter

This would substantially increase the annual tax bill for many property owners.

Worked Examples: Before and After

To understand the impact, here’s a comparison of Income Tax only, Income Tax + NIC, and Limited Company for both basic and higher rate landlords.

Rental Profit	Tax Structure	Income Tax	NIC	Corporation Tax	Total Tax
£20,000	Income Tax Only	£1,486	£0	£0	£1,486
£20,000	Income Tax + NIC	£1,486	£668.70	£0	£2,154.70
£20,000	Limited Company	£0	£0	£3,800 (19%)	£3,800*
£60,000	Income Tax Only	£11,432	£0	£0	£11,432
£60,000	Income Tax + NIC	£11,432	£3,587.60	£0	£15,019.60
£60,000	Limited Company	£0	£0	£15,000 (25%)	£15,000*

*Corporation Tax only; dividends drawn later may incur additional tax but no NICs.

Key Insight: NICs on rental profits would meaningfully increase the tax burden, especially for higher-rate landlords, and reinforces the benefits of incorporation.

Why This Matters

The UK rental market is under pressure:

• Higher mortgage costs
• Section 24 mortgage interest restrictions
• Rising energy and compliance costs

Adding NICs would further squeeze landlords, particularly those running smaller portfolios or with marginal profits. Seasonal boosts and rental growth may no longer offset the higher tax burden.

Going Limited: A Stronger Case

Incorporating your property business has several advantages:

• Corporation Tax rates (19–25%) are generally lower than Income Tax + NIC for high earners
• No Class 4 NIC on profits held inside the company
• Reinvestment opportunities – profits can be used to acquire additional properties without immediate tax leakage

This strategy becomes even more compelling if NICs on rental income are introduced.

Recommendations for Landlords

1. Review your portfolio – Identify properties at risk of becoming unprofitable.
2. Consider incorporation – A limited company structure shields profits from NICs and may reduce overall tax.
3. Forecast cash flow – Rising tax bills make planning essential.
4. Plan withdrawals carefully – Dividend strategies are key to minimising overall liability.
5. Seek professional advice – Each landlord’s circumstances differ, and early planning is critical.
