Quick answer

CIS-heavy practices file a monthly return by the 19th for every contractor client, on top of usual bookkeeping and tax work. Practice software that tracks recurring monthly deadlines, per-client custom fields and reminders keeps these returns from being buried among everything else.

What does practice software need to offer a CIS-focused firm?

It needs a reliable way to track a monthly deadline, by the 19th, for every contractor client, plus a place to record subcontractor details and verification status without a separate spreadsheet per client.

Firms with a construction-heavy client base carry an extra monthly deadline that non-CIS clients don't: the CIS return, due by the 19th of the month following the tax month. Multiply that across dozens of contractor clients and the operational load is significant, on top of the usual quarterly and annual work.

This isn't a CIS filing or calculation tool — that stays with your specialist CIS or accounts software. What most firms are missing is the tracking layer: which client's return is due, whether subcontractor details are up to date, and who owns each return this month.

Why does CIS deadline tracking keep slipping?

The 19th comes round fast

A monthly deadline leaves very little breathing room between returns, especially when it lands close to other month-end work like VAT or payroll.

Contractor client lists change

Subcontractors join and leave jobs regularly, and keeping each client's list current in a spreadsheet is easy to fall behind on.

Verification status gets lost

Knowing which subcontractors have been verified with HMRC, and which haven't, needs a reliable record, not a memory of the last email.

No single view across contractor clients

Without a shared list, it's hard to see at a glance which of many contractor clients still have an outstanding return this month.

Penalties compound quickly

CIS late filing penalties escalate the longer a return is outstanding, so a delay that seems minor in week one becomes costly by month three.

What does a late CIS return cost a practice or its clients?

HMRC applies escalating penalties for late CIS monthly returns, starting shortly after the deadline and increasing the longer the return remains outstanding, on top of the client relationship damage of repeated lateness.

CIS monthly returns are due by the 19th of the month following the tax month, and penalties apply from the first day late, increasing at set intervals. [VERIFY] current CIS penalty amounts and escalation points on GOV.UK.

For a practice managing many contractor clients, repeated lateness — even where penalties are modest per instance — adds up and signals a systemic tracking problem rather than a one-off mistake.

How do you manage CIS deadlines across a construction-heavy client book? Step by step

  1. 1

    List every contractor client with their CIS obligation

    Flag which clients are contractors under CIS, since not every construction client will be, and this list changes as clients grow.

  2. 2

    Set a recurring monthly task per client

    Create a repeating task for the return itself, due ahead of the 19th, so it doesn't rely on remembering the deadline exists.

  3. 3

    Record subcontractor details on the client record

    Use custom fields to hold subcontractor names, UTRs and verification status against each contractor client.

  4. 4

    Build in an internal cut-off before the 19th

    Give yourself a few days' buffer to chase missing subcontractor information before the actual filing deadline.

  5. 5

    Track verification status separately

    Note which subcontractors are verified and which are pending, so nothing is paid at the wrong deduction rate by mistake.

  6. 6

    Review outstanding returns weekly during the run-up

    A short weekly check of what's still open in the days before the 19th catches stragglers early.

How does Remindoo help CIS and construction-focused practices?

Remindoo tracks the operational side of CIS work: a recurring task for each contractor client's monthly return, due ahead of the 19th, regenerates automatically so nothing depends on someone remembering the cycle. Custom fields let you record subcontractor details, UTRs and verification status directly on the client record, replacing a separate spreadsheet per client. Clients by type makes it simple to filter your contractor clients specifically, so a busy month doesn't bury CIS work among unrelated tasks. Automated reminders flag returns approaching the deadline, and trigger dates let you build in a buffer before the 19th so late subcontractor information doesn't cause a last-minute scramble. This does not calculate or file CIS returns — that stays with your specialist software — but it keeps every client's deadline visible and owned, free to try for 60 days.

Frequently asked questions

Does Remindoo file CIS returns with HMRC?

No. Remindoo does not perform CIS filing, calculations or HMRC submissions — it tracks the operational deadlines and subcontractor records alongside your specialist CIS software.

Can I filter clients to see just my CIS contractor book?

Yes, clients by type lets you filter and view your contractor clients separately from the rest of your client base.

How does the free 60-day trial work for a CIS practice?

You get full access to set up recurring monthly CIS tasks and custom fields for at least one full monthly cycle, with no charge until you decide to continue.

Can I record subcontractor verification status per client?

Yes, custom fields let you capture verification status, UTRs and other subcontractor details directly against the client record.

Does this help with the CIS deadline specifically or all deadlines?

It tracks all your firm's deadlines in one place, including CIS returns, so contractor clients aren't managed in a separate system from the rest of your work.

What if a subcontractor's status changes mid-month?

Update the custom field on the client record as soon as you're notified, so the next return reflects the correct status without relying on memory.

Why recording every task matters in an accountancy practice

Accounting firms run on deadlines: VAT returns, payroll, confirmation statements, accounts and Self Assessment. Recording every job as a task, with an owner and a date, is the simplest way to make sure nothing is missed.

Avoid penalties

HMRC and Companies House charge penalties for late filing. A task for every deadline, with an internal date before it, gives the team a buffer.

Nothing depends on memory

Recorded tasks mean work continues when someone is off sick, on leave or has left the firm.

Consistent quality

Subtask checklists make every job follow the same steps and reviews, whoever does the work.

Visibility for managers

Filters by owner, status and deadline show at a glance what is late, what is due and who needs help.

Practical tips from UK practice

  • Set an internal deadline two to four weeks before every statutory deadline.
  • Use recurring tasks for repeat work such as VAT, payroll and bookkeeping.
  • Break larger jobs into subtasks, including a review step.
  • Comment on the task instead of by email, so the history stays with the work.
