MAKING TAX DIGITAL (MTD) WITH STANDARD ERP

Businesses with a taxable turnover that exceeds the VAT registration threshold (currently £85,000) need to submit their VAT return following the Making Tax Digital (MTD) criteria from April 2019. Please follow the steps below to link Standard ERP to your government gateway account and prepare your VAT Return to be submitted directly to HMRC.

To prepare your Standard ERP VAT report to ensure that the correct figures correspond to the correct boxes of the HMRC Vat Return:

1. Nominal Ledger >> Report Settings >> VAT Report >> flip B.
2. Add the corresponding box of the VAT return to the correct calculation in the VAT report.


In System>> Settings>> Company Info >> Reg tile, The VAT number must be entered correctly (i.e. GB xxx xxxx xx) in the VAT Reg. No. field.

To submit your VAT Return to HMRC, you need to grant access to allow the software to submit your VAT return on your behalf.
This access is granted for 18 months, after which you will need to grant the access again.

First allow access, through Access Groups, to a person or group of people who should be in charge of managing your VAT Submissions to HMRC.
In System >> Settings >>Access Groups >> Amend HMRC Access token with level Full.
This will allow a user to edit the Electronic VAT Declaration setting.
