The Nil Corporation Tax Return Trap Affecting Many Managing Agents

Many flat management companies across the UK may be filing Corporation Tax Returns with HMRC unnecessarily, simply because “that’s how it has always been done.”

Over the years, we have reviewed a number of Residents’ Management Companies (RMCs) and Right to Manage (RTM) companies where accountants had been preparing and submitting nil Corporation Tax Returns year after year, despite the companies having no taxable income at all. In many of these cases, managing agents and directors were paying annual accountancy fees to file CT600 returns showing no Corporation Tax due, no taxable profits and no taxable income.

When we reviewed these companies in detail, we asked one simple question: “What taxable income does the company actually receive?” Very often, the answer was none.

The companies were not receiving ground rent income, garage rental income, telecom mast income, commission income, investment income or any other form of trading income. Instead, they were simply collecting service charges from leaseholders and using those funds to pay for repairs and maintenance, insurance, reserve fund expenditure, communal utilities and general block management costs.

In other words, these companies were acting purely as managers or trustees of service charge monies on behalf of leaseholders. Once properly reviewed, it became clear that in many of these cases, the companies may never have needed to file Corporation Tax Returns in the first place.

The legal position is rooted in UK leasehold legislation. Under Section 42 of the Landlord and Tenant Act 1987, service charge monies collected for dwellings are generally held on trust for leaseholders. This is extremely important because the service charge funds do not beneficially belong to the management company itself. The company is effectively administering funds on behalf of leaseholders rather than generating profits for its own benefit.

The Landlord and Tenant Act 1985 further supports this principle by giving leaseholders rights to inspect and challenge service charge expenditure, reinforcing that service charges are collected specifically for maintaining the building rather than generating profit for the company. 

Most flat management companies simply collect service charges, arrange insurance, pay contractors, organise repairs, maintain reserve funds and manage communal areas. These activities alone do not usually create taxable trading profits. Since the service charge monies are generally trust monies belonging to leaseholders, they are normally outside the scope of Corporation Tax for the company itself. Therefore, where the company has no separate beneficial income, there may be no Corporation Tax liability at all.

Corporation Tax may still apply where the company receives income belonging beneficially to the company itself, such as ground rent income, garage rental income, advertising income, rooftop telecom licence income, commissions retained by the company or taxable bank interest. In those situations, the company would normally still need to file annual CT600 Corporation Tax Returns.

In many of the cases we reviewed, once it was established that there was no taxable income, HMRC was notified that the company was dormant for Corporation Tax purposes. HMRC subsequently removed the ongoing requirement to file annual CT600 returns. Many managing agents and directors were genuinely surprised to learn that this was possible. For years, nil returns had simply been filed because nobody had ever questioned whether the filing obligation actually existed.

HMRC guidance confirms that where a company is dormant for Corporation Tax purposes, there is normally no requirement to continue filing Corporation Tax Returns unless the position changes. 

One important point to understand is that dormancy for HMRC purposes is not always the same as dormancy for Companies House purposes. The company may still need to prepare statutory accounts, file annual accounts and submit confirmation statements to Companies House because the company still legally exists and continues administering service charge trust funds. However, from HMRC’s perspective, the company may still be dormant for Corporation Tax purposes if it has no taxable income.

Flat management companies operate in a very unique legal and tax environment. In many of the cases we have encountered, the issue was not unpaid tax. It was simply that nobody had ever stopped to ask whether the Corporation Tax Return was required in the first place.
