If you’ve had a quiet year with no income at all, it’s natural to wonder whether you still need to file a Self Assessment tax return. Plenty of tradespeople find themselves in this spot maybe work slowed down, you took time off for family reasons, or you switched between CIS, PAYE, and small bits of self-employment.
Here’s the thing: HMRC doesn’t always care about whether you earned anything. What they care about is whether you were expected to file. That’s where people get caught out.
Let’s break it down, so you know exactly where you stand and what you need to do.
Why HMRC might still expect a return
A lot of contractors assume that no income means no filing. Unfortunately, that’s not always the case. If HMRC has asked you to submit a return, you’re legally required to send one even if the numbers are all zeros.
Here are the common situations where HMRC still expects a return:
1. You’re registered as self-employed
Even if you didn’t pick up a single job, you’re inside the system. Until you formally tell HMRC you’ve stopped trading, they’ll wait for your return every year.
2. You worked under CIS earlier in the year
HMRC often keeps you marked as someone who needs to file. If you were active earlier in the tax year even for a few weeks they want the full picture.
3. You received a notice to file
This one is non-negotiable. A notice to file means HMRC expects a return, income or no income.
4. You had untaxed income earlier in the year
Maybe you had a few jobs before everything slowed down. Even if it didn’t add up to much, HMRC still wants the figures.
When you don’t need to file
There are situations where no income genuinely means no filing:
- You’ve never registered as self-employed
- You’ve been on PAYE only
- You’ve notified HMRC that you stopped trading and they confirmed the closure
- HMRC removed the filing requirement from your record
But here’s what catches people off guard:
Just stopping work doesn’t automatically cancel your filing obligations. You have to tell HMRC.
What happens if you skip filing?
Even with no income, ignoring a required return can trigger:
- £100 late filing penalty
- Additional penalties after 3, 6, and 12 months
- HMRC compliance checks
- Debt collection letters
And it doesn’t matter that you earned nothing. HMRC charges penalties based on non-compliance, not income.
This is why thousands of tradespeople get unnecessary fines every year fines they could have avoided with a zero-income return.
Filing a zero-income return is easier than you think
A lot of tradespeople assume a tax return means loads of paperwork. Not in this case.
A zero-income return is literally you confirming:
- No income
- No expenses
- No trading activity
It’s quick, clean, and ticks the box for HMRC.
And once your return is filed, you can also ask HMRC to remove your filing requirement if you’ve genuinely stopped trading.
Why filing with no income can actually help you
Here’s the part most people don’t realise.
Even if you earned nothing, filing still:
Keeps your record clean
HMRC sees you’re compliant and leaves you alone.
Prevents penalties
A £0 return is cheaper and faster than fighting a fine.
Helps with future mortgage or credit applications
Some lenders like to see continuous filing, even with no income.
Allows you to claim refunds if CIS was deducted earlier in the year
You might still be due money back.
What if you stopped trading?
If you stopped working for yourself, you must tell HMRC you’ve ceased trading.
If you don’t, they’ll still expect a return next year.
To stop Self Assessment properly:
- Contact HMRC (online or phone)
- Confirm your stop-date
- File your final return
- Ask them to remove the filing requirement going forward
Once they confirm the closure, you won’t need to file again unless you restart your business.
What if you switched to PAYE?
If you moved into a PAYE job and had no self-employment income, HMRC may still expect a return if you were registered earlier in the year.
This is where people often get confused.
Example:
You worked self-employed for two months in April and May, then took a PAYE job.
Even if you left your trade and stopped invoicing, HMRC still views you as someone who needs to file for that tax year.
After submitting that one return, you can get them to remove the requirement.
What if you’re not sure?
If you don’t know where you stand, there’s a simple way to find out:
- Check your HMRC online account
- See if there’s a Self Assessment section
- Look for any notices to file
- Check whether a return is overdue
If a return is showing, it doesn’t matter whether income was zero you’re expected to file.
Final thoughts
Not earning anything doesn’t always mean you’re off the hook. If HMRC expects a return and you don’t file, you risk penalties even when income is zero. But the good news is that filing a zero-income return is quick, straightforward, and protects you from fines.
If you’re unsure whether you need to file, get someone to look at your HMRC record. It takes minutes and could save you a lot of stress.
