The process

How it works.

01

Connect HMRC

One-time setup - your credentials are stored securely and never shared.

02

Add client by NINO

Enter your client's National Insurance Number. Their profile is created instantly. When they connect via DoneTax or DoneSE using your practice code, their data flows to you automatically.

03

Receive client data

Your client categorises their transactions in DoneTax or DoneSE. Each quarter, their cartridge lands in your dashboard automatically. No chasing. No manual entry.

04

Review and submit

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

Bank-grade security · AES-256 encryption · HMRC fraud prevention headers · ICO registered

The Cartridge Model

Every quarter is a cartridge.

Most tax software was built for one person filing their own return. DoneTax+ was built the other way around - for an agent filing for many. 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. Each quarter the cartridge lands in your dashboard - 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 itself. Each active client seat costs an additional £1.99 per month. You only pay for clients you have added. Remove a client at any time and billing stops immediately. There is no minimum client count.
No. You connect your HMRC Agent Services Account once via secure OAuth 2.0. After that, adding clients is instant using their National Insurance Number. HMRC authorisation flows automatically through your agent credentials for every client you manage.
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 the quarter closes, you receive a completed cartridge in DoneTax+, review it, approve it, and submit directly to HMRC. No chasing. No manual data entry. No back and forth.
Never. Clients use DoneTax or DoneSE on their own devices. DoneTax+ is your platform only. Clients enter a practice code when they sign up and from that point you are connected. They never see your dashboard.
All four quarterly submission deadlines and the Final Declaration for every client in your practice. The dashboard flags upcoming deadlines across your full client base so nothing falls through the cracks.
Transactions can currently be entered manually or pulled directly from HMRC via open banking. 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 client seats, subject to the per-seat fee. The platform is built to scale with your practice from day one.
All data is encrypted at rest and in transit using AES-256. Servers are UK-based. The platform is fully GDPR compliant and registered with the ICO. We never store or see your HMRC credentials. Your agent OAuth token is held in encrypted session storage only.
Your clients use DoneTax for property income or DoneSE for self-employment income - both at £4.99 per month. They connect to your practice by entering your practice code when they sign up. From that point their quarterly data flows automatically into your DoneTax+ dashboard. No spreadsheets, no emails, no manual re-entry on your end.
DoneTax+ is preparing for public launch. Join the waitlist and we'll notify you the moment it's available for your practice.
