More than 7,000 farmers have now been paid bridging payments of around 50% of likely Basic Payment Scheme (BPS) 2015 claim amounts.
Together with over 90 percent of farmers who have received a full BPS payment, this means that all eligible farmers have now received a payment.
Announced two weeks ago, the bridging payments to remaining farmers were made to help with cash flow pressures.
All other claimants, in total more than 90%, have received their full claim payment by the end of April.
Rural Payments Agency Chief Executive Mark Grimshaw said: "These payments have been made by the end of April, as promised, to help remaining applicants facing financial pressures.
"With around 55% of anticipated 2016 claims already submitted or underway, we are helping those still to apply to meet the 16 May deadline.
"All farmers should complete their application before the deadline even if they are waiting for the balance of the 2015 payment."
Mr Grimshaw said he was fully aware of the "frustration and anxiety" felt by farmers still waiting for their money and acknowledged that the RPA "could have done more".
"It's been an incredibly challenging year, our experiences from 2015 will give us valuable insights into 2016."
