How to add your VAT and CIS settings
Set whether you're VAT registered, add your VAT number, and turn on CIS if you work as a subcontractor.
Both settings live on your company details, and both change how your invoices are calculated. Leave either off if it doesn't apply to you.
Note
Company settings can only be changed by an owner. If you're not the account owner, these fields are visible but greyed out.
Add your VAT settings
- Go to Settings, then select Company under Business.
- Find VAT and switch on
I am VAT registeredif it applies to you. - Enter your VAT number, for example
GB 123 4567 89. - Select Save.
The switch tells Trame whether new quote and invoice lines should start with VAT. Your VAT number is shown on the quotes and invoices you send. If you're not VAT registered, leave the switch off.
Turn on CIS
CIS applies if you work as a subcontractor under the Construction Industry Scheme.
- On the same page, find Construction Industry Scheme.
- Switch on
I work as a CIS subcontractor. - Set your Deduction rate:
Registered (20%),Not registered (30%), orGross payment status (0%), matching your CIS registration status with HMRC. - Select Save.
Note
CIS is a deduction, not a loss. It reduces what the customer pays you upfront, but Trame's reports still count the full value of the work as your revenue.
With this off, no CIS options appear on your invoices at all. With it on, you can choose to apply the CIS deduction on an invoice, invoice by invoice, it isn't forced onto every one.
Frequently asked
Do I need to turn on CIS if I'm not a subcontractor?
No. Leave it off. It only adds options for subcontractors under CIS, it doesn't change anything else about your invoices.
Can I change the deduction rate later?
Yes, if your registration status with HMRC changes, come back and update the rate here.
