Company Accounts and Tax software
Your bookkeeping already lives in Xero, so your company accounts and Corporation Tax Return (CT600) are prepared from the same records. Review the figures, confirm them, and file with Companies House and HMRC without leaving Xero. Your records stay organised for whenever you bring in an advisor.
Bookkeeping, accounts and tax in one place
The transactions you capture and reconcile in Xero through the year flow straight into your company accounts and Corporation Tax Return. Nothing to re-enter, no separate tools, and no rebuilding your figures at year end. Just review, confirm and file.
Everything stays connected
Your bookkeeping feeds your accounts and tax in Xero, with no spreadsheets and no re-entering numbers.
File without leaving Xero
Send your company accounts to Companies House and your CT600 to HMRC, in one connected workflow.
Ready for what's next
Keeping your bookkeeping, accounts and tax together gives you a strong base as the company grows.
From receipt to return, without re-keying
Snap a photo of a receipt, or forward a bill straight from your email, and Smart Document Capture reads the key details and files them in Xero for you. There's no manual data entry and no shoebox of paperwork to sort at year end. Your records are ready the moment you need them.
- Bank feeds, bills, receipts and invoices all flow into the same accounts, so you start year end with figures you already trust
- Your accounts and CT600 use the same records in Xero, so there's nothing to export between tools
- Prepare and file in one place, instead of moving between Xero and separate filing portals
Your bookkeeping flows directly into your accounts and tax
The records you keep through the year feed straight into your accounts and CT600, so there's no scramble to enter everything at year end.

Built for smaller limited companies
If you run a small limited company and file your own year end, or you used to file through HMRC's CATO service, this add-on is sized for exactly that. It's a straightforward way to prepare and submit your company accounts and corporation tax return, and it suits micro-entity (FRS 105) filers.
- Prepare micro-entity (FRS 105) accounts and your CT600 from the data already in Xero
- Handle basic trade capital allowances, and simple or no carried forward losses
- File to Companies House and HMRC from inside Xero
Company accounts and tax software for small limited companies
The Company Accounts and Tax add-on is built for owner-managed limited companies with simple, straightforward affairs.
A strong base to work with an advisor
Filing yourself today doesn't mean going at it alone later. Your bookkeeping stays in Xero, so an advisor you invite in picks up the records rather than starting again. Your company accounts and CT600 can be exported and shared with them whenever you need to.
- Last year's figures stay in Xero, so each year end builds on the one before
- Invite an advisor into your Xero organisation to work alongside you on the bookkeeping
- Export your accounts and CT600 in a format an advisor can pick up
Ready for your business as it grows
Your bookkeeping stays in Xero as the company grows, so bringing in an advisor later is a step up rather than a fresh start.
Getting Xero made the whole business more efficient. It made accessing the accounts so much easier.

How filing your accounts and tax works
Accounts and corporation tax run through the same flow, so your year end is one job rather than two.
Keep your records as you go
Bank feeds and Smart Document Capture bring your bills and receipts into Xero throughout the year.
Review your accounts and CT600
Both are drawn from the same set of records, so you're checking the figures rather than building them.
Submit to Companies House and HMRC
File both from Xero, and get swift confirmation once Companies House and HMRC respond.

A Company Tax Return is the paperwork or digital form (such as form CT600 in the UK) you file with the government, while Corporation Tax is the actual money or tax bill that your business owes on its profits. You use the company tax return to calculate how much corporation tax you need to pay.

The CT600 is the form that makes up your Company Tax Return. It reports your profit, adjusts it for tax purposes and works out the corporation tax due for the accounting period. Software like Xero prepares the CT600, carries out the calculation and lets you submit it to HMRC, so you check the figures rather than work them out on paper. You have to file the CT600 online with HMRC, normally within 12 months of your accounting period ending, and the payment deadline falls earlier than that.

FRS 105 is the reporting standard for micro-entities. Your company usually qualifies by meeting two of three size thresholds covering turnover, balance sheet total and employee numbers. Micro-entity accounts are shorter than full statutory accounts, with a simplified balance sheet and profit and loss account. Xero's accounts production software prepares yours in that format.
