The stakes
One missed date is one client too many.
A practice with 60 clients tracks several hundred deadlines a year, across a spreadsheet, Outlook reminders, and one senior person's memory. It works, right up until the week it doesn't.
A single missed filing is a penalty for your client and a dent in the trust that keeps them with you. That is not a software problem. It is a reputation problem.
Memory does not scale
What one person holds in their head is a risk the whole practice quietly carries.
Suites are overkill
TaxDome and Karbon are powerful, and priced per user for CRM, invoicing and workflows you did not ask for.
Nothing sat in between
Until now, there was no calm middle ground between a spreadsheet and a full practice suite.
What it does
The one thing that keeps you out of trouble.
Not a practice-management suite. Just every client, every deadline, and the proof you filed, organised so your team can file with confidence.
Every deadline, one screen
Add a client once. FilingKeeper works out every statutory date and shows what is overdue, due this week and due this month in a single calm view.
Reminders before it hurts
Automatic email at 30, 14, 7 and 1 days before each deadline, plus a daily digest for the practice. Nothing slips because someone was on leave.
Status your team can trust
Move each filing from not started to submitted, with who marked it and when. No more asking whether anyone actually filed it on the 31st.
Proof kept with the deadline
Attach the confirmation or receipt to the deadline it belongs to. When a client questions a filing, the evidence is one click away.
Built for a team
Assign work to staff, filter by teammate or client, and see the whole practice at a glance, not one senior person's memory.
Narrow, and safer for it
Names, dates and flags only. No financial figures, no HMRC logins. Less sensitive data means a smaller risk to carry for you and your clients.
Coverage
Every UK filing your clients face.
One national rule set covers every client: limited companies, sole traders and partnerships alike. The dates are derived from each client's own year-end and obligations, then adjusted for weekends and bank holidays.

Rules follow published UK guidance and are verified before launch. FilingKeeper flags anything uncertain rather than showing a date it is not sure of, because a wrong date helps no one.
A simple rhythm
Live in an afternoon.
No migration project. No onboarding call to schedule. Add clients, and your deadlines are there.
- 01
Add the client
Record the entity type, year-end and which filings apply. About a minute per client.
- 02
Deadlines appear
The engine builds a rolling 12-month schedule for that client, checked against UK bank holidays.
- 03
Assign, file, record
Move work through the team, file it yourself, and mark it submitted with proof attached.
Where it fits

Narrow by design
Less data to hold. Less to worry about.
We chose to store client names, dates and filing flags, nothing more. No financial figures, no HMRC credentials, no personal tax records. It keeps your compliance burden low, and it is one less thing that can go wrong on your watch.
Reached through the app only
Business data is never queried from the browser.
Kept isolated per firm
Every query is scoped to your practice, with database-level isolation behind it.
Every change is traceable
Submission timestamps and an audit trail stay with the work.
Pricing
One missed penalty costs more than a year of this.
Every plan has the same focused workflow. You only choose how many clients you track. 14 days free, no card to start, and two months free on annual billing.

From the founder
Built for the practices the big suites forgot.
FilingKeeper is made by a small team for small firms: the ones tracking client deadlines in a spreadsheet because the alternatives cost more and do far more than they need. It does one job, and it takes that job seriously.
The first 10 practices to come on board get 3 months free, in exchange for a short feedback call each week. You help shape it; you get the reliability without the price of a suite.
Claim a founding placeQuestions
The things practices ask first.
Do you file to HMRC or Companies House for me?
No, and we never will. FilingKeeper reminds you and records what you filed. You stay in control of every submission, so responsibility for a filing is never handed to a tool.
How are the dates worked out?
From each client's own dates and obligations: VAT stagger, accounting reference date, self assessment and payroll, using the published UK rules and adjusted for weekends and bank holidays.
Is my client data safe?
We deliberately store names, dates and flags only. No financial figures, no HMRC credentials, no personal tax data. Your data is held in the UK and reached only through the application, never queried from the browser.
What if I go over my client limit?
Move up a plan whenever you need more capacity. The workflow is identical on every plan, so you are only ever paying for how many clients you track.
Do I need a card to try it?
No. Start the 14-day trial, add your clients, and see your real deadlines before you decide. Cancel any time.
Bring every client deadline into one calm view.
See your real deadlines in minutes. No card to begin.
