Xero managing director Victoria Crone said the proposed changes were a positive step forward and would mean time saving and easier use for customers, particularly for those that paid provisional tax - where revenue for the year was estimated and then tax calculated from the estimate.
"[With provisional tax] companies sometimes get lumped with big payments or not depending on the estimate," Crone said.
"Most businesses do want to pay tax and don't want to stuff it up so it can cause a fair amount of stress when you get the provisional tax payments wrong. So there's time saving and also less stress on the business when you know where you stand and your tax payments are better."
PwC tax and private business leader Geof Nightingale described the proposed changes as fundamental and ambitious.
"The tax system touches nearly every New Zealander and redesigning the tax system is a huge challenge. It is crucial any changes are well considered and implemented as seamlessly as possible," he said.
"Small businesses in particular would feel compliance costs in coping with the changes falling on them disproportionately in the shorter term, however New Zealand businesses will be better off in the longer term, with the changes set to save them costs and time."
Crone said the move online would also allow for faster dealing with tax issues and reduce errors with information being able to be quickly and securely transferred to the IRD without the need to manually copy data and fill in paper returns.
"So it's time saving for customers ... there's less opportunities for mistakes."
McClay said the Government planned to deal with tax administration and PAYE/GST rules, and withholding taxes on labour income this year, followed by initiatives on investment income information, individuals' interactions with the IRD, and business taxation. Social policy interaction with the tax system would be tackled in 2017.
Tax plan
How is tax currently paid?
Under the current system GST and PAYE are paid three to four times a year, and often estimated for the full year at the end-of-year return.
How will the proposed system work?
Under the new system tax can be paid and calculated more frequently, giving companies a better idea of tax status.
Why is this being changed?
The change is part of a move to modernise and simplify the tax system in the next three years to increase the rate and accuracy of tax collection.
