The proposal by Her Majesty's Revenue and Customs (HMRC) stresses the need for employers to provide real-time information to the government so that it can monitor all payments and make a better assessment of whether the correct tax is being paid.
Currently employers withhold tax and pay the government, providing information at the end of the year, a system know as Pay as You Earn (PAYE). There is no option for those employees to refuse withholding and individually file a tax return at the end of the year.
If the real-time information plan works, it further proposes that employers hand over employee salaries to the government first.
"The next step could be to use (real-time) information as the basis for centralizing the calculation and deduction of tax," HMRC said in a July discussion paper.
HMRC described the plan as "radical" as it would be a huge change from the current system that has been largely unchanged for 66 years.
Even though the centralized deductions proposal would provide much-needed oversight, there are some major concerns, George Bull, head of Tax at Baker Tilly, told CNBC.com.
"If HMRC has direct access to employees' bank accounts and makes a mistake, people are going to feel very exposed and vulnerable," Bull said.
And the chance of widespread mistakes could be high, according to Bull. HMRC does not have a good track record of handling large computer systems and has suffered high-profile errors with data, he said.Read More
