CIS Deductions (MTD) API

Version and status
Available in Sandbox	Yes
Sandbox base URL	https://test-api.service.hmrc.gov.uk
Available in Production	Yes
Production base URL	https://api.service.hmrc.gov.uk

Overview

Under the Construction Industry Scheme (CIS), contractors deduct money from a subcontractor’s payments and pass it to HM Revenue and Customs (HMRC). The deductions count as advance payments towards the subcontractor’s tax and National Insurance.

Contractors must register for the scheme. Subcontractors don’t have to register, but deductions are taken from their payments at a higher rate if they’re not registered.Here a developer can:

create CIS deductions where they have not previously registered with HMRC
override CIS deductions which have been previously populated when creating their record
retrieve a list of CIS deductions for a subcontractor that has been previously populated
remove CIS deductions that have been previously populated

Versioning

When an API changes in a way that is backwards-incompatible, we increase the version number of the API. See our reference guide for more on versioning.

Errors

We use standard HTTP status codes to show whether an API request succeeded or not. They are usually in the range:

200 to 299 if it succeeded, including code 202 if it was accepted by an API that needs to wait for further action
400 to 499 if it failed because of a client error by your application
500 to 599 if it failed because of an error on our server

Errors specific to each API are shown in the Endpoints section, under Response. See our reference guide for more on errors.

Single errors will be returned in the following format:
{ "code": "FORMAT_FIELD_NAME", "message": "The provided FieldName is invalid" }

Where possible, multiple errors will be returned with INVALID_REQUEST in the following format:
{ "code": "INVALID_REQUEST", "message": "Invalid request", "errors": [ { "code": "RULE_FIELD_NAME", "message": "The provided FieldName is not allowed" }, { "code": "FORMAT_FIELD_NAME", "message": "The provided FieldName is invalid" } ] }

Testing

You can use the sandbox environment to test this API. You can use the Create Test User API or it's frontend service to create test users.

It may not be possible to test all scenarios in the sandbox. You can test some scenarios by passing the Gov-Test-Scenario header. Documentation for each endpoint includes a Test data section, which explains the scenarios that you can simulate using the Gov-Test-Scenario header.

If you have a specific testing need that is not supported in the sandbox, contact our support team.

Some APIs may be marked [test only]. This means that they are not available for use in production and may change.
