Making Tax Digital for Income Tax is live · Your £50k+ clients are filing quarterly now

Your clients.
Their tax.
Done.

DoneTax+ was built the other way around - for an agent filing for many, not one person filing for themselves. Your clients log their own income and expenses in DoneTax or DoneSE and send you each quarter when it's ready. Review, approve, and file for every client from one dashboard - no chasing, no logins to juggle, no spreadsheets. Client apps from £4.99/mo.

Why DoneTax+ for Making Tax Digital for Income Tax

Built for agents.
Not adapted.

FULL AUDIT TRAIL

Every Making Tax Digital for Income Tax review, approval and submission is recorded with the time it happened. A clear record for every client.

ADD BY NINO

No lengthy onboarding. Enter your client's National Insurance Number and they get a connection request in DoneTax or DoneSE. Once they accept, they appear on your dashboard. Works with both DoneTax landlord clients and DoneSE sole trader clients.

DIRECT HMRC SUBMISSION

OAuth 2.0 authenticated via your HMRC Agent Services Account. File quarterly updates and year-end tax returns without leaving the platform.

The process

How it works.

01

Connect HMRC

One-time setup - you sign in at HMRC, and we never see your Government Gateway password.

02

Add client by NINO

Enter your client's National Insurance Number. They get an invite in DoneTax or DoneSE and accept it in their own app.

03

Receive client data

Your client categorises their transactions in DoneTax or DoneSE. When they're done they send the quarter, and it arrives as a cartridge in your dashboard ready to review. No chasing. No rekeying.

04

Review and submit

Review the completed cartridge, approve it, and file directly to HMRC via the Agent Services Account API. Full audit trail.

AES-256 encryption · HMRC fraud prevention headers · ICO registered

The Cartridge Model

Every quarter is a cartridge.

DoneTax+ was built for practices from the start - for an agent filing for many clients. Each client-quarter becomes one cartridge, moving through a single controlled lifecycle, so nothing slips between you and HMRC.

The quarterly lifecycle
IncompleteReadyUnder ReviewSubmittedFinalised

Need changes? Flag the cartridge back and it returns for another pass. Nothing reaches HMRC until you approve it.

Your clients do the data entry

They categorise their own income and expenses in DoneTax or DoneSE. When they're ready they send the quarter and it arrives as a cartridge - no chasing, no logins to juggle, no rekeying.

Review equals filed, to the penny

The figures you approve on a cartridge are exactly what reaches HMRC, and exactly what is written back to your client. Nothing is recalculated behind the scenes.

Every client in one place

One cartridge per client, per quarter, per income type - every one tracked through the same lifecycle on a single dashboard. You run the whole practice from one screen.

Simple pricing

One platform. One price.

Got questions

Frequently asked.

Yes, without exception. DoneTax+ is built exclusively for UK tax agents and accountants managing Making Tax Digital for Income Tax submissions on behalf of clients. Individual taxpayers cannot access this platform. If you are looking for personal tax management, DoneTax handles property income and DoneSE handles self-employment.
Your monthly or annual subscription covers the platform for your whole practice. There is no charge per client and no minimum client count.
Yes - once per client, and DoneTax+ runs it for you. You connect your HMRC Agent Services Account once via secure OAuth 2.0. For each client you then request authorisation from within DoneTax+ using their National Insurance Number and postcode. They approve it at their own Government Gateway, and DoneTax+ tracks the status until it comes back authorised.
Yes. DoneTax+ handles both income types in a single dashboard. Landlord clients connect through DoneTax and sole traders through DoneSE. Both feed into your DoneTax+ command centre through the Cartridge Model.
Each quarter of data for each client is a cartridge. Your client logs their income and expenses in their own app throughout the quarter. When they send the quarter, it arrives as a completed cartridge in DoneTax+ for you to review, approve, and submit directly to HMRC. No chasing. No rekeying. No back and forth.
Never. Clients use DoneTax or DoneSE on their own devices. DoneTax+ is your platform only. You invite them by National Insurance Number and they accept in their own app. They never see your dashboard.
All four quarterly submission deadlines for every client in your practice. The dashboard flags upcoming deadlines across your full client base so nothing falls through the cracks.
Transactions reach a cartridge two ways today: your client sends their categorised quarter from DoneTax or DoneSE, or you add and edit transactions directly on the cartridge. CSV import and integrations with popular bookkeeping tools are on the roadmap. If you have a specific integration requirement, contact us.
No. Both the monthly and annual plans include unlimited clients. The platform is built to scale with your practice from day one.
HMRC access tokens, National Insurance numbers and the stored copy of each filed quarterly update are held using AES-256 encryption. Our database is hosted in the UK. We process personal data under UK GDPR and are registered with the ICO. We never see your Government Gateway username or password - you sign in at HMRC. The access token HMRC issues is encrypted at rest and used only to file for your clients.
Your clients use DoneTax for property income or DoneSE for self-employment income - both at £4.99 per month. You invite them from DoneTax+ and they accept in their own app. They categorise as they go and send you the quarter when it's ready, so it arrives in your dashboard as a cartridge. No spreadsheets, no emails, no rekeying on your end.
DoneTax+ is in early access ahead of public launch. Request early access and we'll email you the moment your account is ready.
