What you get

Zoho Sign sits inside Client Review, so a signature counts just like an approval in Tax Optimiser.

One document to sign

The accounts, computation and CT600 are combined into one PDF, with a final approval page carrying the directors' approval statement and the HMRC declaration.

Self Assessment too

Send an SA100 return from its Client review card. The sign-off page carries the SA100 declaration.

Dates filled in

When the director signs, the director signage date is set to the date they signed (or the CT600 declaration date for a Corporation Tax-only request). Dates you've entered are never changed.

Live status

See when a request is out for signature, opened, signed, declined or expired. Remind or withdraw it from the same panel. Declined requests show the client's reason.

Signed copy kept

The signed PDF and Zoho's completion certificate are saved against the review, ready for your files.

Your own Zoho account

Each firm connects its own Zoho Sign account. Tax Optimiser never sees your password, and the access is stored encrypted.

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.

Zulfiqar Ali Google review

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.

Robert B Google review

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.

Frequently asked questions

Not from Tax Optimiser. Connecting Zoho Sign is included in your account. Zoho charges credits for each document sent through its API, currently 5 credits per envelope, and you buy those from Zoho.

A plan with API access: Zoho Sign Enterprise, or the Zoho Sign API plan with credits. On the API-only plan you can only send through integrations such as Tax Optimiser, so choose Enterprise if you also send from Zoho Sign directly.

No. Zoho emails your client a signing link and they sign in their browser. Zoho sends reminders every 5 days, and the request expires after 30 days.

Yes. Each request goes to one signer, so send a separate request to each director who needs to sign.

Yes. Turn on test mode in your firm's Integrations settings. Test documents are watermarked, use no credits, and Zoho allows up to 50 a month.

You sign in to Zoho and approve access, so Tax Optimiser never sees your Zoho password. We only ask to create and read signature requests, and the access is stored encrypted. You can disconnect at any time.

Sign-off without the chasing.
