I remember the first time I registered a dormant company. I thought I had it all figured out – file some paperwork, keep it on ice, and activate it when the time was right. Then reality hit. One small transaction later, I found myself frantically Googling “have I accidentally activated my dormant company?” at midnight.
If you’re in the same boat, don’t worry. The line between dormant and active isn’t as complicated as it seems once you know what to look for.
What’s a dormant company anyway?
Think of a dormant company as a business that’s taking a nap. It exists on paper, but it’s not doing anything – no trading, no income, no business transactions. Maybe you’ve registered a brilliant business name you want to protect, or perhaps you’ve temporarily shut down operations.
HMRC and Companies House consider your company dormant when it’s not:
- Trading with customers
- Buying and selling things
- Earning money from investments
- Paying salaries
- Basically doing anything business-related
The moment everything changes
Here’s the thing about dormancy – it ends the second you dip your toe into business activities. There’s no grace period or warning bell. One minute you’re dormant, the next you’re active.

Real-world triggers that wake up your sleeping company
I’ve seen it happen countless times. A director thinks, “I’ll just pay myself a small dividend” or “Let me buy this laptop through the company” – boom, active status.
Your company springs to life when you:
- Sell even one product or service
- Buy business supplies (beyond basic formation costs)
- Pay yourself or anyone else
- Earn interest on company investments
- Receive any kind of income
I once had a client accidentally activate their company by accepting a £50 speaking fee through their business account. That tiny transaction triggered full reporting requirements!
What won’t wake the sleeping giant
Not everything counts as activation. Your company can still snooze peacefully while:
- Paying your annual Companies House fee
- Covering accountancy costs for dormant accounts
- Settling any Companies House penalties
- Issuing shares (provided no trading has started)
What to do when the alarm goes off
Once your company wakes up, the paperwork begins:
- Tell HMRC within 3 months (they don’t appreciate surprises)
- Register for corporation tax
- Switch from those lovely simple dormant accounts to full annual accounts
- Prepare to file corporation tax returns
- Think about VAT if your turnover is heading toward the threshold
I learned this the hard way when I missed notifying HMRC about a company activation. The penalties weren’t fun, and explaining the oversight was even less enjoyable.
When things go wrong
Miss these steps and you’re looking at:
- Late filing penalties that grow by the day
- Interest charges that compound faster than you’d like
- Potential HMRC investigations (trust me, you don’t want this)
- A corporate reputation that takes a hit
Planning the wake-up call
If you’re intentionally activating your dormant company, do yourself a favor:
- Mark a clear start date on your calendar
- Get your accounting systems ready before, not after
- Talk to an accountant before making moves
- Have a plan for what happens next
The reality check
I’ve guided dozens of businesses through this transition, and here’s the truth: the moment your company becomes active isn’t when you decide it does or when you tell HMRC. It’s when you make that first business move.
Stay on top of your company’s status, communicate changes promptly, and you’ll avoid the midnight panic searches I’ve both experienced and witnessed too many times to count.
