Durham Property Investors: Don’t Let These Tax Changes Destroy Your Returns

2025...The Year of Tax Changes

If you’re a landlord or property investor in Durham, 2025 is shaping up to be a year of major tax challenges. New rules and tightening reliefs mean your property portfolio could end up costing you more than you expect.

But with the right planning, you can stay compliant and protect your profits.

In today's blog, we’ll break down:

✅ The key tax changes landlords need to know

✅ How they’ll hit your rental returns

✅ Proven strategies to reduce your property tax bill

Why 2025 Is a Critical Year for Property Tax Planning

HMRC and the government are under pressure to raise revenue—and landlords are in the firing line.

Several tax changes introduced in recent years are now fully biting, and 2025 brings even more challenges, including:

• Reduced Capital Gains Tax (CGT) allowances

• Frozen income tax thresholds, pushing landlords into higher bands

• Tighter Mortgage Interest Relief restrictions already in place

• Additional compliance requirements for reporting rental income

Ignoring these could mean paying thousands more to HMRC than you need to.

5 Key Tax Changes Hitting Durham Landlords

1️⃣ Capital Gains Tax Allowance Slashed

The CGT annual exemption has been reduced again, meaning when you sell a rental property, you’ll pay tax on more of the gain.

What it means for you:

• Selling now without planning could lead to a bigger tax bill

• More investors are being pushed into planning sales over multiple years

2️⃣ Frozen Tax Bands = Higher Bills

Income tax thresholds have been frozen until at least 2028. That means even if rents just keep pace with inflation, landlords can drift into higher-rate tax.

Example:

A Durham landlord charging £800/mo rent in 2020 may now get £950. That extra income risks pushing them into 40% tax if their other earnings are close to the threshold.

3️⃣ Mortgage Interest Relief Restrictions Still Bite

Since the relief changes in 2020, landlords can only claim a 20% tax credit for finance costs—not deduct them in full.

High-rate taxpayers end up paying much more than before, especially with rates rising.

4️⃣ Making Tax Digital (MTD) for Income Tax

From 2026 (originally 2024), landlords earning over £50,000 will need to comply with quarterly digital submissions to HMRC.

2025 is the year to get ready:

• New software

• Better bookkeeping

• Avoiding penalties for non-compliance

How These Changes Can Destroy Returns

Without planning, the impact is severe:

✅ Smaller net rental yields

✅ Higher CGT on sales

✅ Reduced cashflow if tax takes a bigger bite

✅ More admin and compliance risk

This can make once-profitable Durham buy-to-lets financially unviable—or seriously erode your retirement plans.

5 Proven Ways to Protect Your Property Profits

But it’s not all bad news. Smart investors can still protect their returns. Here’s how:

✅ 1. Consider Incorporating

Company ownership can offer lower corporation tax rates

• More flexible mortgage interest relief

• Better inheritance planning options

But beware: setup costs and mortgage access need careful analysis.

✅ 2. Use Spousal Transfers to Optimise Tax Bands

• Shift ownership to a lower-rate taxpayer spouse

• Save thousands annually on income tax

✅ 3. Plan Sales Over Multiple Tax Years

• Spread disposals to use both spouses’ CGT exemptions

• Time sales before future rate changes

✅ 4. Improve Record-Keeping for MTD

• Get compliant ahead of time

• Avoid penalties

• Make claiming all allowable expenses easier

✅ 5. Work with a Specialist Accountant

• Tailored planning for your portfolio

• Up-to-date on all Durham and UK tax changes

• Proactive advice to stay ahead of HMRC
