Manual Adjustment of VAT
Sometimes you receive a purchase invoice and the VAT Amount does not exactly match the VAT calculated by Accounting Seed. MTD for Accounting Seed includes Tax Groups to help.
- Enter the Payable (Purchase Invoice) in the normal way
- Add an extra line to the Payable:

- VAT Adjustment2
- QUANTITY: 1
- UNIT COST: The adjustment amount – this can be positive or negative
- EXPENSE GL ACCOUNT: Your Purchase Tax Control Account
- TAX GROUP: ‘VAT ADJUSTMENT’
This will generate a single posting to the ‘Purchase Tax Control’ and the VAT added to the Box 4 total.
For example:
- If you have a receipt for £100 plus £12 VAT (maybe a mixture of VATable and non-VATable items), Accounting Seed will calculate £20 VAT, but you can only reclaim £12.
- Adding a ‘VAT ADJUSTMENT’ line with -8.00 the correct amount will be posted to the ‘Purchase Tax Control’ account (£12).
- When the VAT Return is processed, the Box 4 value would be reduced by £8.00
