What We Do

Tax advice built
around bricks
& mortar

Every landlord's position is different — a single flat, a growing portfolio, a holiday let, an inheritance. We give clear, specialist counsel on the decisions that move the needle.

Portfolio Structuring

Personal name, partnership or limited company? We model the long-game and structure your holdings for tax efficiency and clean succession.

Capital Gains Tax

Selling a rental? We plan disposals, claim every relief, handle the 60-day CGT return and make sure you never overpay a penny.

Learn more →

SDLT & Acquisitions

Stamp Duty is a minefield of surcharges, reliefs and multiple-dwellings rules. We get the figure right before you exchange.

Learn more →

Self-Assessment

Property pages, finance-cost restriction, allowable expenses — your annual return prepared and filed, on time, optimised to the line.

Learn more →

Incorporation Relief

Moving a portfolio into a company can unlock significant savings — or a tax bill. We test incorporation and execute it properly.

Learn more →

Inheritance & Trusts

Pass property to the next generation without handing 40% to the Exchequer. Estate planning, trusts and family investment companies.

Why Keystone

A high-street accountant treats property as a footnote. We treat it as the whole book.

Property tax is a discipline of its own — Section 24, the 60-day rule, the residential CGT rate, ATED, the SDLT surcharge maze. We've spent eighteen years in nothing else, and it shows on every return we file.

  • Specialists, not generalists

    Chartered tax advisers (CTA) who live and breathe landlord legislation, all day, every day.

  • Proactive, not reactive

    We flag the disposal, restructure or relief before the deadline — not in a panic the night before.

  • Fixed fees, no surprises

    Transparent pricing agreed up front. You'll never open an invoice you didn't expect.

How It Works

From first call to filed return

01

Discovery Review

A relaxed conversation about your portfolio, your plans and your pain points. We map where you stand today.

02

Tax Position Audit

We model your exposure across income, CGT, SDLT and IHT — and quantify exactly where money is leaking.

03

The Strategy

A clear, written plan: what to restructure, when to sell, which reliefs to claim, and the saving attached to each.

04

Execution & Filing

We implement, liaise with HMRC and file every return — then keep the strategy under annual review.

"A portfolio is built over decades. The tax planning should be too."

Marcus founded Keystone after a decade inside a Big Four property tax team, frustrated that the smartest planning was reserved for the largest estates. He brought that thinking to private landlords — the family with three flats, the investor with thirty.

Today he leads a team of chartered advisers who treat every client's portfolio as if it were their own — patient, precise and relentlessly on the lookout for the next legitimate saving.

Client Words

Landlords who sleep easier at tax time

★★★★★
Keystone found a CGT relief my old accountant had completely missed. The saving paid their fee twenty times over — on a single sale.

They walked us through incorporation step by step and were honest that it wasn't right for two of our flats. That candour is exactly why we trust them.

Inheriting my father's rentals was overwhelming. Keystone handled the probate tax, the SDLT and the restructuring with real calm. Worth every penny.
