So your UK limited company didn’t make a penny last year. You’d think that means there’s nothing left to do – no profit, no tax, no forms, done. That’s not how HMRC sees it, though. Whether you owe them anything has almost nothing to do with what landed in your bank account, and if you’re in the process of closing the company down, those tax obligations don’t just evaporate the second you post off a strike-off form. They have to be dealt with first, properly, in the right order.

This applies just as much if you’re running things from outside the UK. A lot of Pakistani and NRP founders set up a UK LTD, gave an idea a go, and either it never really took off or they simply decided to stop. The company just sits there, quiet, while its director is in Karachi or Lahore, thousands of miles away. It’s easy to assume that distance, or the fact that nothing was ever traded, loosens the rules somehow. It doesn’t. UK non-resident director tax obligations on a company with no profit are identical to what they’d be for someone sitting in an office in London. The rules attach to the company, not to wherever its director happens to be living.

Before reading further, figure out which of these actually sounds like you:

• Never traded at all? Mostly this comes down to HMRC dormancy rules – skip ahead to “Stopping Trading vs Closing” below.
• Traded, but broke even or lost money? You’ll want the sections on taxable profit and terminal loss relief.
• Stopped trading and want out, with nothing to show for it? Go straight to the final accounting period and DS01 strike-off sections – that’s the order that matters for you.
• Closing a company that made some profit, or still holds assets? This particular guide isn’t really aimed at you – extraction and distribution tax is its own separate topic.

Everything below is written mainly for the first three groups – people dealing with genuinely nothing, or next to nothing, to report.

What “No Profit” Actually Means for Corporation Tax

Worth clearing this up early: “no profit” showing in your bank account isn’t automatically the same thing as “no profit” as far as HMRC is concerned. The two can drift apart in small but meaningful ways, so it’s worth understanding why before assuming you’re off the hook for filing.

Accounting Profit vs Taxable Profit

Accounting profit is simply what your books show – income minus expenses – and for a company that genuinely didn’t trade, that figure might sit right at zero. Taxable profit works differently. HMRC runs its own adjustments over that accounting figure, adding back expenses that aren’t allowable for tax, or handling capital allowances in a way that doesn’t quite match how they appear in your books.

Put simply, taxable profit is the number HMRC actually works from to decide what you owe, if anything. A company can post £0 accounting profit and still end up with a small taxable adjustment once disallowed costs or timing quirks get factored in. That’s rarely dramatic for a tiny company with no real trading behind it, but it’s exactly why “we made nothing” and “we owe nothing” aren’t always the same sentence.

Do You Still Have to File a Company Tax Return With No Profit?

Yes. This is where most founders trip up. Whether you need to file has almost nothing to do with how much profit you made and almost everything to do with whether HMRC is expecting a return from you at all.

What a Nil Return Is (and Isn’t)

A nil Company Tax Return – shortened, usually, to a nil CT600 – is exactly what the name implies: a formal statement to HMRC that for this particular accounting period, there’s no taxable profit and nothing owed. It’s not some shortcut that skips the usual process. It is the process, just with a zero sitting at the bottom of it instead of a number.

In short: A nil Company Tax Return (nil CT600) is a formal filing declaring that a UK company has no taxable profit and owes no Corporation Tax for a given accounting period. It’s still legally required if HMRC has sent a Notice to Deliver (CT603), even for a company that has never once traded.

The nil CT600 deadline follows exactly the same rule as any other Company Tax Return – there’s no relaxed timeline just because the final answer is zero. Missing that deadline is what triggers a penalty, not the fact that there happened to be nothing to pay. If you’re not sure exactly when yours falls due, check with whoever handles your filing rather than guessing at it.

One thing worth flagging while we’re here: HMRC’s free online CT600 filing portal closed on 31 March 2026. That free option, which plenty of small companies leaned on for exactly this kind of simple nil filing, is gone now. Filing means either commercial software or an agent, which is a bigger shift than it sounds for anyone managing things from overseas. If you’re doing this from Pakistan and don’t already have UK filing software set up, it’s usually simpler to hand the job to a specialist than to buy and learn a new system just for one nil return a year. That’s the gap our UK Corporation Tax filing service is built to close.

What Happens If HMRC Issued a “Notice to Deliver”

If HMRC has sent your company a notice to deliver a Company Tax Return – the CT603 – that notice puts a legal obligation on you to file. Doesn’t matter if the company never traded, broke even, or lost money every single month it existed. Once that notice arrives, a return is due, and “there was nothing to report anyway” doesn’t cancel that requirement. The only way to stop future notices for a company that’s genuinely inactive is to formally tell HMRC it’s dormant.

Break-Even and Loss-Making Companies: What Changes

Losing money doesn’t get you out of filing either, but there’s at least one upside worth knowing about, especially if you’re winding things down.

If You Made a Loss in Your Final Year

If your company made a trading loss in its last twelve months, that loss can sometimes be carried back up to three years and set against profits – and tax already paid – in those earlier periods. That’s terminal loss relief, and for a company that had a decent stretch before things slowed down, it can mean an actual refund rather than a loss going nowhere. The mechanics turn technical fast, so this is one to raise with whoever’s preparing your final return rather than trying to work out solo, but it’s a good reason not to assume a loss-making close-out is automatically a dead end.

Be realistic about it, though. For a genuine micro-company that paid little or no tax in prior years, getting an agent to calculate and file a full terminal loss carry-back can end up costing close to whatever refund it actually brings in. If that’s roughly your situation, it’s often more sensible to just focus on a clean, low-cost nil filing that closes the company off properly, rather than chasing a relief that barely covers its own paperwork.

Stopping Trading vs Closing the Company – They’re Not the Same Thing

Lots of confusion sets in right here, and it’s an easy mix-up to make. Stopping trading is an operational decision. Closing the company is a legal one. They can happen months apart, and treating them as the same thing is where problems start.

Worth being clear too on what actually counts as trading for Corporation Tax purposes. HMRC generally treats a company as trading if it’s actively buying, selling, providing services, or otherwise running some kind of business activity, not just holding a bank account or sitting registered and unused. A company that’s genuinely inactive, with no income and no business activity at all, is the one that can look at dormancy instead of ongoing filing.

HMRC Dormancy vs Companies House Dormancy

“Dormant” means something slightly different depending on who you ask, and founders often assume satisfying one automatically covers the other. It doesn’t.

• HMRC dormancy: means the company isn’t trading and has no other income for Corporation Tax purposes. You have to tell HMRC this yourself, directly – it’s not something inferred from your Companies House filings.
• Companies House dormancy: relates to filing simpler “dormant accounts” because the company hasn’t had any significant accounting transactions. Separate test, separate requirements.

Filing dormant accounts at Companies House tells HMRC precisely nothing. You can end up perfectly compliant with one system while quietly falling behind on the other – an especially easy trap when you’re managing everything remotely from Lahore, juggling two government systems, two logins, two different definitions of the same word. If that’s where you’re stuck, our guide to dormant companies walks through both sides properly.

Your Final Accounting Period, Explained

Here’s something that catches a lot of first-timers off guard: the date your company stops trading isn’t just a casual marker on a calendar. It ends your current Corporation Tax accounting period on the spot, that same day, whether or not it lines up with your normal year-end.

Say your company usually runs its accounting year April to March. Stop trading in October, and that October date becomes the end of a short “stub” period – April through October – and that stub needs its own Corporation Tax return, on its own timeline, separate from whatever annual rhythm you’d gotten used to. Miss this and you can easily think you’re covered until next March, when actually a return fell due months earlier without you realising. Our full UK Corporation Tax Guide covers accounting periods in more depth if you want the bigger picture.

Final Corporation Tax Obligations Before You Close

Once you’ve decided you’re closing rather than leaving the company dormant, two things need to happen before Companies House will let the dissolution go through cleanly.

The Final CT600 Return

The stub period created when trading stopped needs its own final CT600 return, covering everything from the end of your last full accounting period through to the date you stopped. It’s not optional, and it’s not something you can wave away with “well, there was no profit anyway.” Filing it properly is what actually closes the loop with HMRC. If commercial filing software isn’t something you want to navigate for what’s probably a one-off return, our UK Corporation Tax filing service exists exactly for this kind of final filing.

Settling Outstanding Liabilities

Any tax due – even a small amount thrown up by those taxable profit adjustments mentioned earlier – has to be paid. A company can’t be cleanly closed while it still owes HMRC money, and assuming the debt will just disappear along with the company is one of the more common, and more costly, mistakes founders make at this stage.

Laid out in order, a proper wind-down looks like this: stop trading, which immediately ends your accounting period and creates the stub; file the final CT600 covering that stub period; pay whatever tax it shows as due; and only then move on to applying for strike-off. Do these steps out of order, especially jumping straight to strike-off, and that’s where most delays and rejections come from.

How This Interacts With Companies House and Strike-Off

This is the part that genuinely trips people up, and it’s worth getting straight before filing anything with Companies House.

Why HMRC Can Hold Up a DS01 Strike-Off

When you apply to strike off a company using form DS01, Companies House doesn’t just process that on its own. Once the strike-off application is published, HMRC gets notified and checks it against its own records. Mostly this is a systems check rather than someone sitting down and manually reviewing your file, which is exactly why it catches so many people off guard. If your final CT600 hasn’t been filed, or there’s unpaid tax sitting on the account, HMRC can, and regularly does, formally object to the strike-off. The whole application stalls until the outstanding return gets filed and the debt gets settled.

Picture a founder in Pakistan who registered a UK company two years back, never really got it trading, and figures the simplest move is to file for strike-off and be done. Weeks later, the application gets rejected, and now they’re sitting overseas trying to work out why a company they assumed was basically empty is being blocked from closing. The answer’s almost always the same – an unfiled final return, or an unpaid balance nobody dealt with before the DS01 went in. Sort the tax first, then apply to close, and that whole loop disappears. If you’re at this stage, our company closure guide lays out the order these steps need to happen in.

Common Mistakes to Avoid

Most of the trouble here comes down to the same handful of assumptions, just wearing slightly different outfits.

1. Assuming no profit means no filing. It doesn’t. Filing duties come from HMRC notices and company status, not from your bank balance.
2. Treating Companies House dormancy as if it covers HMRC too. Separate systems, separate requirements, no overlap.
3. Overlooking the stub period entirely. Stopping trading ends your accounting period right then and there – it doesn’t politely wait for your usual year-end.
4. Filing for strike-off before tax affairs are actually settled. Far and away the most common cause of a blocked or delayed dissolution.
5. Letting late-filing penalties sit until they escalate. From April 2026, a late Company Tax Return starts at a £200 penalty, climbing to a cumulative £400 once you’re three months late, and it keeps growing the longer a return goes unfiled. Already got a penalty notice? Get help resolving a Corporation Tax penalty before it turns into something harder to unwind.

Frequently Asked Questions

Do I need to file a Corporation Tax return if my company made no profit? Yes, and profit level doesn’t really decide this. Once HMRC has issued a notice to deliver a return, you have to file, even at £0, unless the company’s been formally registered as dormant with HMRC.

What is a nil Corporation Tax return? It’s a Company Tax Return (CT600) confirming that no tax is owed for that period. Same process as any other return, it just ends at zero.

What happens if my UK limited company never traded at all? If HMRC’s already asked for a return, you either tell them the company’s dormant to stop future requests, or file a nil return covering whatever period they’ve asked about.

What’s the difference between a dormant company and a closed company? Dormant means it still legally exists, it just isn’t trading. Closed means it’s been formally dissolved, so the legal entity is gone.

Do I still need to file accounts with Companies House if I file a nil CT600? Yes, definitely. A nil CT600 only satisfies HMRC’s side of things. Companies House has its own separate requirements – annual accounts, a confirmation statement – regardless of what your tax position looks like.

Can I close a UK company that still owes HMRC money? You can submit the DS01, but expect HMRC to object if there’s unpaid tax or an unfiled return sitting there. It’s much cleaner to settle everything first.

Does closing my company cancel any Corporation Tax I owe? No. Dissolving the company doesn’t wipe out tax debts or unfiled periods from before. HMRC can object to the closure, and in some cases can even apply to have the company restored later to recover what’s owed.

What if HMRC objects to my company being struck off? Companies House pauses the strike-off. You’ll need to file whatever’s outstanding, settle any tax owed, and clear up any penalties before that objection lifts.

I’m a non-resident director living in Pakistan – do my UK tax obligations change? No, not at all. The obligations belong to the company as a UK-registered entity, not to wherever the director’s based. Nil or final returns, and any outstanding tax, still need sorting regardless of location.

Settle Your UK Compliance Cleanly

Zero profit doesn’t mean zero paperwork, and closing a company doesn’t erase whatever came before it. If you’re sitting on an unfiled nil return, a stub period you didn’t even know existed, or a strike-off that’s stalled because HMRC objected, the fix is usually far more straightforward than it feels from where you’re standing, especially once someone who does this every day is handling the filing instead of you piecing it together from Lahore or Karachi at midnight. Our UK Corporation Tax filing service can take the final CT600, the nil return, or the overdue filing off your plate and get your company’s tax affairs properly closed out.
