Tax Returns Done Right —without the stress.
Most business owners dread tax season. We get it — confusing forms, tight deadlines, and real penalties if something goes wrong. DgTx handles every step so you don’t have to lose a single night’s sleep.
Missing the deadline costs more
than hiring us.
HMRC charges automatic penalties from day one. A £100 fine lands the moment you’re late — and that’s just the start. Don’t let an avoidable mistake hurt your business.

We know what keeps
business owners up at night.
You didn’t start a company to become a tax expert. Here are the problems we hear every single day — and exactly how DgTx fixes them.
“I have no idea when my corporation tax return is due.”
It’s not the same date for every company. It depends on your accounting period — and HMRC doesn’t send reminders.
DgTx tracks your specific deadline and alerts you well in advance.
“The forms look like they’re written in a foreign language.”
CT600 forms, computations, supplementary pages — it’s a lot. One wrong box and your return could be flagged or rejected.
Our accountants prepare everything correctly, first time.
“I don’t know if I’m paying too much — or too little.”
Overpay and you lose money. Underpay and HMRC will come looking. Both hurt your business.
We check every allowable deduction so you pay exactly what you owe — no more, no less.
“I keep putting it off and now the deadline is close.”
It happens to everyone. Rushing a tax return is one of the fastest ways to make expensive mistakes.
We can turn around most returns fast — even if you’ve left it late.
“My last accountant quoted me something ridiculous.”
Accountancy fees for a straightforward corporation tax return shouldn’t break the bank. Yet here we are.
Transparent, fixed pricing. You know the cost upfront — no surprises.
“What happens if I just… don’t file?”
Spoiler: HMRC notices. Penalties build up automatically. Interest accrues. It gets messy — and costly — fast.
Don’t risk it. DgTx gets you compliant quickly and quietly.

When is my corporation tax return due?
Your corporation tax return (CT600) must be filed with HMRC within 12 months of the end of your accounting period. However, the tax itself is due to be paid within 9 months and one day of your accounting period ending. These are two different deadlines — and both matter. We track both for you.
What is a corporation tax return, exactly?
It’s a formal document — the CT600 form — that tells HMRC how much profit your company made and how much Corporation Tax you owe. Every limited company must file one each year, even if you made no profit or owe no tax. Not filing is not an option.
Can I file my corporation tax return online?
Yes — and in fact HMRC requires online filing for almost all companies. DgTx files directly with HMRC on your behalf using approved software. You’ll receive instant confirmation once your return is submitted.
What does an accountant charge for a corporation tax return?
Fees vary depending on the complexity of your business and the quality of your records. At DgTx, we charge a fixed fee — you’ll see the exact price before you commit to anything. Most small company returns start from a very competitive rate. Check our pricing section below.
What happens if I don't file my corporation tax return?
HMRC issues automatic penalties. You’ll receive a £100 fine the day after your filing deadline passes. If you’re three months late, another £100 is added. Beyond six months, penalties become percentage-based — and interest accrues on top. The longer you leave it, the worse it gets.
Can you file a corporation tax return if my accounts aren't in order?
Yes. We work with businesses at all stages of record-keeping — including those where things are a bit disorganised. We’ll let you know exactly what we need and help you pull it together. It’s always better to file something than to file nothing.
Do I need to do anything after DgTx files my return?
Mainly just pay your tax bill by the 9-month-and-one-day deadline if you haven’t already. We’ll send you a clear summary showing exactly what you owe and when. After that, you’re done until next year — at which point we’ll reach out to start the process again.
