Self-employed and behind on tax? What to do
Falling behind on your tax isn’t as uncommon as you might think. Work can be unpredictable, cash flow can be tight, and before you know it a deadline has passed.
If you’re in that position, the most important thing is not to ignore it. There are usually options available, and the sooner you deal with it, the better.
Check exactly where you stand
Start by getting a clear picture of what’s outstanding.
- Which tax year is affected?
- Have you submitted the return?
- Do you know roughly how much is owed?
If your return hasn’t been filed yet, that’s the first priority. HMRC can’t agree any payment arrangements until they know the amount due.
File your return as soon as possible
Even if you can’t afford to pay right now, submit the return.
Late filing penalties build up quickly, and they’re separate from any interest on unpaid tax. Getting the return in stops further filing penalties and puts you back in a better position to sort the rest.
Don’t ignore HMRC letters
It’s tempting to put them aside, but it only makes things worse.
HMRC will usually:
- add penalties
- charge interest
- eventually begin collection action
If you respond early, they’re generally more flexible.
Look at a payment plan
If you can’t pay in full, you may be able to set up a Time to Pay arrangement.
This allows you to:
- spread the cost over monthly payments
- avoid more serious enforcement action
You’ll still pay some interest, but it’s far better than letting the debt sit.
Be realistic about what you can afford
When agreeing a plan, make sure the payments are manageable.
Overcommitting can lead to missed instalments, which may cancel the arrangement and put you back to square one. It’s better to agree something sustainable from the start.
Check if you’re missing anything
Sometimes the bill is higher than expected because:
- expenses haven’t been claimed properly
- income has been estimated
- previous returns weren’t fully completed
It’s worth reviewing things to make sure you’re not paying more than you should.
Get help if you need it
If you’re unsure where to start, speaking to an accountant can take a lot of the pressure off. They can:
- bring your records up to date
- deal with HMRC on your behalf
- help set up a payment plan
- make sure everything is correct going forward
- 8. Put something in place for next time
Once things are under control, it helps to avoid the same situation again.
Simple steps can make a big difference
We recommend:
- setting money aside regularly for tax
- keeping records up to date
- checking in on your position during the year
Final thoughts
Being behind on tax can feel stressful, but it’s usually fixable. The key is to deal with it early, understand your options, and take it one step at a time.
If you leave it, it tends to grow. If you tackle it, it becomes manageable.
