The overwhelming majority of businesses  say the rise in employers' NICs will force them to change their plans,  according to research by the British Chambers of Commerce (BCC).
With under six weeks until the NICs rise  comes in, 82% of firms say the tax hike will cause them to rethink. In  addition, 58% of surveyed businesses say it will impact recruitment plans, and  54% that it will affect their prices.
Meanwhile, more than a third of firms  suggest investment and day-to-day operations will be impacted.
Alex Veitch, Director of Policy at the  British Chambers of Commerce said:
'The  clock is ticking down to the NICs rise, and firms are already telling us they  are sitting on a powder keg of costs.
'The  government has pledged to retain the NICs tax position through the life of this  parliament, but our new evidence should give pause for thought. We need the  government to publish a wider tax roadmap for business, setting out the  direction of travel for costs like NICs and business rates. 
'Business  rate reform must be an urgent priority, creating a system that incentives  investment. Getting on with planning and skills reforms will also remove  blockers to growth.'
