Nearly one in five farmers have still not received their BPS payments for last year.
With this year’s applications just around the corner some 17 or 18 per cent have still not received last year's money.
In 2014, 97 percent of farmers had received their payments by December, showing that there is still a lot of work that needs to be done.
However Richard Wordsworth, the NFU’s senior advisor on the Basic Payment Scheme, said that the Rural Payments Agency had made changes to this year’s applications with a move to a more online system.
Richard said that this year will most likely be a stepping stone and that he expects more improvements to be made for next year.
The Rural Payments Agency is aiming towards the majority of applications being made online in a bid to speed up processing times.
Richard spoke to FarmingUK TV at Scotch Corner during one of many special BPS meetings organised by the NFU over the next month.
NFU Cymru warns the Welsh Government that patience is wearing extremely thin amongst the farming community.
Stephen James, NFU Cymru President said: "Nearly five months into the payment window I am extremely concerned that hundreds of farmers across Wales have yet to receive their BPS part payment.
"This is unacceptable especially when you consider that Welsh Government made the decision last year to introduce part payments in an effort to ensure timely delivery of the new Basic Payment Scheme.
"I am particularly concerned for our cross border farmers who have not yet been paid as a result of the failure of the paying agencies in England and Wales to effectively share data.
"Farmers are struggling following a difficult winter, costs have mounted as a result of record rainfall and commodity prices remain depressed, meaning cash flow is a major issue on all farms."
