Job expense claims, without the paperwork.
Prepare your clients' P87 claims in minutes: mileage, flat rates, fees and receipts worked out from what you enter, the evidence collected through the client portal, and a ready-to-post pack with your ARN on the cover letter. One flat price per claim — never a share of the refund.

The same claim, without the busywork.
HMRC only processes a P87 with evidence attached, and a paper claim goes by post. Here is where the time goes.
| Row | By hand | ac-co |
|---|---|---|
| Filling in the form | Type every box into the PDF | Filled from the claim |
| Mileage | Rates, the 10,000-mile split and employer payments by spreadsheet | Worked out per tax year |
| Getting the receiptsEach upload comes back to the expense it was asked for. | Emails and reminders | Asked for in the client portal |
| P87 or tax return? | Your judgement, every time | Checked against the £2,500 limit and the client's filing |
| Cover letter with your ARN | Write one | In the pack |
| Who gets the refundWe never take a share and never act as nominee. | The client | The client |

One flat price per claim. Never a share of the refund.
Preparing the claim, the review and the estimate cost nothing. You pay once, from your practice credits, when you download the pack — and you see the price before you do.
- The filled P87 (06/26)
- Cover letter with your ARN
- Mileage log when HMRC asks for it
- Evidence through the client portal
- Every pack kept in the client's vault
- The same claim goes into SA102 boxes 17–20
- Filed with the client's Self Assessment
- Evidence carried over to the return
Prices ex VAT. We won't prepare a pack whose fee is more than half of the estimated refund.
What P87 claims are worth to your practice.
An estimate from your own figures. The ac-co cost per claim is your time on ac-co plus the practice pack price (£5), before VAT.
Ready when you are.
Do you file the claim for us?
No. You get a ready pack: the filled P87, your cover letter with your ARN and the mileage log when needed. The client signs the form and you post it. HMRC pays the refund to the client.
What if the client should be on Self Assessment instead?
ac-co checks it first. A claim over £2,500, or for a client who already files a return, goes into SA102 boxes 17–20 of their return — with no P87 fee.
Is it worth it for a small claim?
We show the estimated refund before anything is charged, and we will not prepare a pack whose fee is more than half of it — a tiny claim is better sent by the client through HMRC's free online service.
Who can use the practice pack?
A practice with an HMRC Agent Services Account: your ARN, at least one client HMRC has authorised, and our P87 terms accepted once. Until then, the claim can still be prepared for the client to send themselves.
Which years can we claim?
The current tax year and the four before it — one claim per employer per year. Home-working relief ends from 2026-27, so it is only offered for earlier years.
Every client's expenses, claimed properly.
