If you run a UK company but live outside the UK – say, in Karachi or Lahore – HMRC still expects you to file a Self Assessment return in certain situations. A lot of foreign directors assume that because they don’t live in the UK, they’re off the hook. That’s not how it works.

The mistakes that come up most often aren’t random. They follow a pattern. And the frustrating part is that most of them are avoidable with a bit of clarity on what HMRC actually needs from a non-resident director.

This article covers the most common filing errors, why they happen, and what to watch out for if you’re managing a UK company from abroad.

What Foreign Directors Usually Get Wrong on Self Assessment

The biggest assumption that causes trouble is this: “I don’t live in the UK, so UK tax doesn’t apply to me.”

That falls apart the moment income starts coming in from a UK company – whether it’s a salary, director fees, or dividends. HMRC’s position is fairly straightforward. If you’re earning from a UK source, they want to know about it. Doesn’t matter where you’re based.

The second most common mistake is filing a standard return without the supplementary pages relevant to your situation. For non-resident directors, that usually means missing the SA109 – the residence pages that tell HMRC about your tax status and why you’re filing as someone who doesn’t live in the UK.

Most people don’t know the SA109 exists until someone flags it. By then, the return has already gone in wrong.

Navigating Residency and SA109 Residence-Page Mistakes

The SA109 is a supplementary form that gets attached to your Self Assessment return. It’s where you declare your residence status, any split-year treatment claims, and details about your ties to the UK. For foreign directors, this page isn’t optional – it’s essential.

A common scenario: a founder based in Karachi sets up a UK limited company, receives director fees throughout the year, and files their Self Assessment without the SA109. They report the income but don’t declare their non-UK residency correctly. HMRC then has no clear record of their residence status, which can trigger compliance queries pretty quickly.

Filling in the SA109 incorrectly is just as problematic as leaving it out entirely. Common errors include claiming the wrong number of UK ties, misreporting days spent in the UK, or not completing the statutory residence test questions accurately. These details matter when HMRC is reviewing the return.

Missing or Misreporting UK Director Income and Dividends

Director income and dividends are two separate things, and they’re taxed differently. A lot of non-resident directors blur this line when they file, which creates discrepancies HMRC notices.

Director fees paid through the UK company’s payroll need to be reported as employment income. Dividends drawn from company profits go in a different section altogether. If you’ve been drawing a combination of both – which is common for owner-directors – each needs to be declared correctly and in the right place on the return.

Another frequent issue is underdeclaring dividend income. Some directors only report dividends they physically transferred to a Pakistan bank account, leaving out dividends credited within the UK company. HMRC looks at what was declared or approved at company level, not just what crossed international borders.

Board fees are another grey area. If you’re receiving fees specifically for sitting on the board of a UK entity, those are taxable UK-source income for a non-resident. This one often gets missed entirely.

Filing Errors: Wrong Return Details and Supporting Pages

Beyond the SA109, a surprising number of errors happen in the basic details of the return itself. Things like:

1. Using the wrong tax year – UK tax years run April to April, not January to December.
2. Not including all UK income sources – especially rental income from UK property or interest sitting in UK bank accounts.
3. Leaving out the employment pages (SA102) if you’re on the company payroll as a director.
4. Submitting without a Unique Taxpayer Reference (UTR) or submitting against the wrong one entirely.
5. Filing late and not realising penalties have already started running.

Each of these sounds small on its own. Together, they build a picture of a return HMRC will likely want to query. Once a compliance review starts, it takes time and documentation to close it out.

One thing worth noting: paper returns and online returns have different deadlines. A lot of non-residents default to paper filing, sometimes without realising the deadline is earlier than the online route.

HMRC Compliance Risks and Penalties for Incorrect Returns

HMRC’s penalties for incorrect or late Self Assessment returns aren’t just financial. They can also lead to formal compliance reviews that affect not just you personally but the standing of your UK company.

For a late return: a £100 penalty kicks in immediately after the deadline, even if you owe nothing. That increases at the three-month and six-month marks, and interest runs on unpaid tax from the payment deadline.

For an incorrect return: if HMRC finds inaccurate information – particularly around residency or income – penalties can be levied based on the amount of tax understated and whether HMRC considers the error careless or deliberate. Non-disclosure issues are taken more seriously than simple mistakes.

For non-resident directors specifically, the risk isn’t just personal liability. A director who repeatedly files incorrect returns can attract scrutiny to their UK company’s payroll, dividend declarations, and company tax returns. These things are connected in HMRC’s systems.

If you’re unsure whether your returns are accurate, getting proper UK Self Assessment filing support before HMRC contacts you is a much better position to be in than after.

How Pakistani Founders Can Avoid Common Filing Errors

If you’re based in Pakistan and managing a UK company remotely, a few practical steps make a real difference.

First, confirm your filing obligation each year. Just because you filed last year doesn’t mean your situation is the same this year – income levels, UK ties, and residency status can all shift. A quick review before the tax year ends avoids bigger headaches later.

Second, make sure someone reviews your SA109 specifically. This is the part most general accountants overlook when helping non-resident clients, because they’re simply not used to dealing with these scenarios. It needs to reflect your actual days in the UK, your ties, and any split-year claims that might apply.

Third, keep a clear record of all income from your UK company – salary, dividends, fees – broken down by type. Don’t rely on bank transfers alone. HMRC looks at what was declared at company level.

Fourth, don’t assume the online filing portal will catch your errors. It won’t. The system accepts whatever you submit. Getting a Self Assessment service from someone who actually understands the non-resident director situation is worth it.
