Do You Need To Submit a Tax Return If You Made No Profit At All?

When your business year wraps up and the numbers come in flat — or even in the red — the last thing you want to think about is more admin. But, sometimes you do not have a choice as it is a requirement.

A common question we get at Xenith Wealth is:

“If I made no profit, do I still need to submit a tax return?”

Short answer? Often yes.

Long answer? It depends on why you’re registered and what HMRC expects from you.

Let’s break it down in a clear, no-nonsense way.

1. If You’re Registered for Self-Assessment, HMRC Usually Expects a Return Anyway

Once HMRC issues a notice to file, you’re legally required to submit a tax return — even if you earned nothing, made a loss, or didn’t trade at all.

Why? Because HMRC wants confirmation of your situation, not assumptions.

Failing to file can still trigger penalties, despite £0 tax being due. Unfair? A bit. Avoidable? Absolutely.

2. Trading Status Matters: Did You Actually Trade?

a) You did trade but made no profit = You must file. HMRC still wants the figures, even if they show a loss.

Bonus: Business losses can often be carried forward, reducing future tax.

b) You didn’t trade at all (dormant business) = You may NOT need to file — but only if HMRC agrees you are dormant and removes you from the Self-Assessment system.

If HMRC hasn’t confirmed dormancy, you still need to file.

3. Side Hustles & Small Income: The £1,000 Trading Allowance

If your total self-employed income was under £1,000, you may not need to register for Self-Assessment at all thanks to the Trading Allowance.

However:

• If you’re already registered, you must still file unless HMRC tells you otherwise.

• If HMRC has asked for a return, you must file — trading allowance or not.

4. Limited Companies: Loss ≠ Exemption

For UK companies:

• A Company Tax Return (CT600) is required every year, even if you made zero profit.

• If the company is dormant, you must notify HMRC. They’ll confirm if CT600s are paused.

Important: Companies House still requires annual filings, dormant or not.

5. Rental Property: No Profit Doesn’t Always Mean No Return

If you’re a landlord:

• You must file if HMRC issued a notice or if you received more than £1,000 in rental income.

• You must also file if you want to declare a rental loss for future offset.

No profit doesn’t mean no admin.

6. Why You Should File Even If You Don’t Have To

Filing a return when your numbers are low or negative can actually benefit you:

• Banking losses for future tax relief

• Clean HMRC record (reduces risk of compliance checks)

• Proof of income history for mortgages, visas, funding, etc.

• Avoiding penalties from misunderstood obligations

Sometimes the easiest tax bill is the one that shows your year wasn’t great — and HMRC respects honesty.
