Essentially, it’s worked out as sales or output vat (vat on sales less vat on sales credit notes) minus purchase or input vat (vat on purchases less vat on purchase credit notes). If the answer is positive, you owe HMRC, and if you’ve set up to pay by dd, HMRC will take this a few days after you submit the return. if the answer is negative, HMRC owe you, and again, if a dd arrangement is in place, the money will be paid to you automatically a few days after the return.
Returns and payments are due one month and 7 days after the end of the period, so if your quarter ends 30 June, you will have until early August to sort out the return.
The above refers to the standard VAT scheme. If you’re on cash accounting, annual accounting or the flat rate scheme, there will be differences in how the vat owed is calculated, and the return periods - your accountant will be able to explain all that if necessary.
My procedure is to check all the VAT transactions a couple of weeks after the period end (to give time for everything to be updated/received in post etc), make sure the correct VAT codes have been entered, all the backing documents have been uploaded into the software, query any unusual/doubtful transactions, then run the return, get the director to ok it, and then submit. I would assume that your accountant will do something similar.
The main points are:
- Make sure all the documents are entered in your software, and filed or scanned in.
- Make sure the money is there to pay across when the time comes.
It sounds like you’re doing both of those already, which is great.
