Property Management Accountants Handling Tax, Accounts and Reporting in London, Wimbledon and Essex

Property management accountants handling tax, accounts and reporting take over service charge reconciliations, statutory accounts, Corporation Tax and Companies House filings so your RMC, RTM company or managing agent business stays compliant without eating up your time. If you manage blocks in London, Wimbledon, Old Street, Ilford or across Essex, two 2026 deadlines matter right now: Companies House identity verification for all existing directors must be completed by 18 November 2026, and any RMC that also holds property personally may be caught by Making Tax Digital for Income Tax from 6 April 2026 if gross income exceeds 50,000 pounds.

Property management accounting is the specialist discipline of preparing statutory accounts, service charge and reserve fund reconciliations, Corporation Tax computations and Companies House filings for RMCs, RTM companies and managing agents, distinct from standard landlord tax return work in around forty words.

What Do Property Management Accountants Handle for Tax, Accounts and Reporting?

Property management accountants handling tax, accounts and reporting for RMCs and RTM companies work differently to accountants preparing a standard limited company return. Most of the money moving through a block’s bank account belongs to leaseholders, not the company, so it has to be tracked separately as service charge income and reserve fund contributions rather than turnover. Getting this reconciliation wrong does not just create a messy set of accounts, it can leave directors unable to demonstrate where leaseholder money actually went, which is the single most common source of disputes referred to the First-tier Tribunal.

On top of the reconciliation work, a property management accountant prepares the statutory annual accounts filed at Companies House, calculates and files the Corporation Tax return where the company has taxable income such as bank interest, manages payroll if a caretaker or on-site staff are employed, and advises on VAT where the company recovers costs on works to the building. None of this is optional paperwork. It is what keeps an RMC or RTM company compliant and keeps directors personally protected from the consequences of late or incorrect filings.

Why Do Property Management Companies Need a Specialist Rather Than a General Accountant?

Directors of RMCs and RTM companies are almost always volunteers, usually leaseholders who agreed to take on the role because nobody else would. Few have a finance background, and the compliance calendar for a block is genuinely more demanding than for a small trading company of similar size. A general practice accountant who prepares one set of block accounts a year, without day to day exposure to service charge regulations, is more likely to miss the Section 20 thresholds, misclassify reserve fund money as company income, or overlook the newer Companies House identity verification requirement that specifically affects every director on the register.

GM Professional Accountants works exclusively with property clients across London, Wimbledon, Old Street, Ilford and Essex, from single self-managed blocks of six flats through to portfolios overseen by managing agents. That volume of RMC and RTM specific work means we see the same questions and the same HMRC and Companies House correspondence repeatedly, and we can flag a problem before it becomes one.

What HMRC and Companies House Changes Affect Property Management Companies in 2026 and 2027?

Two changes matter most this year. First, Companies House identity verification became mandatory from 18 November 2025 for every company director, including volunteer directors of RMCs and RTM companies, as part of the Economic Crime and Corporate Transparency Act reforms. Existing directors must verify before their company’s next confirmation statement, with an absolute backstop of 18 November 2026, and unverified directors will simply be unable to file. This has caught out a number of self-managed blocks where directors assumed the requirement only applied to trading businesses.

Second, Making Tax Digital for Income Tax became mandatory from 6 April 2026 for landlords with gross property income over 50,000 pounds, dropping to 30,000 pounds from April 2027 and 20,000 pounds from April 2028. This does not apply to the property management company itself, which pays Corporation Tax as a limited company, but it frequently applies to individual directors who also hold rental property personally, and the two sets of obligations need to be managed together rather than treated as separate problems.

Full detail on Companies House identity verification is published on GOV.UK, and the underlying MTD ITSA thresholds are set out on the HMRC Making Tax Digital pages.

How Do Section 20 Consultation Rules Affect Service Charge Accounting?

Section 20 of the Landlord and Tenant Act 1985 requires a landlord or RMC to formally consult leaseholders before carrying out qualifying works that would cost any single leaseholder more than 250 pounds, or before entering a long term agreement costing more than 100 pounds per leaseholder per year. These thresholds have not changed since 2003, which means a roof repair or a routine cleaning contract can trigger consultation far more easily than most directors expect.

The consequence of skipping consultation is significant from an accounting perspective as well as a legal one. Without a dispensation from the First-tier Tribunal, recoverable costs are capped at 250 pounds per leaseholder regardless of the actual invoice, which means a poorly timed major works project can leave the company absorbing a shortfall that should have come from the service charge account. Separately, Section 20B requires costs to be formally demanded from leaseholders within 18 months of being incurred, so late bookkeeping on invoices can itself cause money to become unrecoverable. Getting the accounting and the consultation timeline right together, not as two separate processes, is where most of the risk sits.

Do You Work with RTM Companies and Managing Agents Across London and Essex?

Yes. GM Professional Accountants is a London based, AAT regulated firm, and our property management accountants handling tax, accounts and reporting work with RMCs, RTM companies and managing agents across London and Essex, with particular depth in Ilford, Wimbledon, Old Street and East London. We serve clients from a first self-managed block of six flats through to multi-site portfolios overseen by professional managing agents. If your company also owns an investment property outside the block itself, our Property investors and landlords team can advise on that side alongside the block accounts, so you are not managing two separate accountants for one portfolio.

Frequently Asked Questions

Do property management companies need a specialist accountant?
Yes. Property management companies, RMCs and RTM companies hold client money, reconcile service charge accounts and file Corporation Tax and Companies House returns under rules that differ from a standard trading business. A general practice accountant without sector experience can miss service charge reserve fund treatment, Section 20 cost recovery limits and RTM specific filing requirements.
What is the Section 20 consultation threshold for service charges?
Section 20 of the Landlord and Tenant Act 1985 requires consultation before qualifying works costing any single leaseholder more than 250 pounds, or long term agreements costing more than 100 pounds per leaseholder per year. Skipping consultation caps recoverable costs at 250 pounds per leaseholder regardless of the actual bill.
Do RTM and RMC directors need to verify their identity with Companies House?
Yes. Since 18 November 2025, identity verification has been mandatory for all company directors, including volunteer directors of Right to Manage and Resident Management Companies. Existing directors must verify before their company files its next confirmation statement, with a final backstop of 18 November 2026.
Does Making Tax Digital affect property management companies?
MTD for Income Tax affects individual landlords with gross property income over 50,000 pounds from April 2026, not property management companies themselves, which file Corporation Tax as limited companies. However, many directors are also personally landlords, so the two obligations often need managing together.
How long do we have to bill leaseholders for service charge costs?
Section 20B of the Landlord and Tenant Act 1985 requires costs to be demanded from leaseholders within 18 months of being incurred. Miss this window without sending the correct written notice and the costs generally cannot be recovered, which makes timely bookkeeping essential.
What does a property management accountant actually do day to day?
A property management accountant reconciles service charge and reserve fund accounts, prepares statutory annual accounts and Corporation Tax returns, manages payroll where staff are employed, advises on VAT partial exemption, and keeps Companies House filings including confirmation statements and director identity verification up to date. Full detail on the underlying legislation sits on legislation.gov.uk.
