File your dormant company accounts for £5
A dormant company still has to file accounts with Companies House every year. Enter your company number, check the details we pull from Companies House, and submit your dormant accounts. If HMRC has asked for a Company Tax Return, you can send a nil CT600 in the same step.
File dormant accounts£5 + VAT (£6 inc VAT) per company per year. No subscription.

Accounts and nil CT600 together
If HMRC has asked for a Company Tax Return, the nil CT600 goes in the same step as the accounts. One fee covers both.

What our customers say
I recently used Tax Optimiser for the first time to submit my accounts to Companies House and HMRC, and I’m thoroughly impressed. The platform is remarkably easy to manage, walking you through the entire process without any complex jargon. On top of that, their prices are extremely competitive. It saved me a ton of time and stress—I will definitely be using them again next year.
I had next to no confidence that Tax Optimiser could handle accounts submission and Corporation Tax. But I gave it a whirl… Both Companies House and HMRC have initially accepted the submissions… I previously filed on professional software and I paid about £1500. This is dirt cheap.
Excellent software. Very affordable if you're doing your own small company accounts. Links with Xero… Tax Optimiser has been a complete life saver for me.
