HMRC have refused to comment on how they will handle countrywide strikes planned for 10 November.
The industrial action in protest at the Government's public sector pay cap will involve workers within civil and public services, including Revenue members of the Public and Commercial Services Union (PCS).
HMRC said they did not wish to speculate on the numbers of employees who may choose to take strike action and then follow the subsequent overtime ban.
The department did say, however, that it was 'disappointed with the decision reached by the PCS' and remarked that it believes the pay deal on offer to be fair.
The Revenue added that is is 'committed to ensuring that during [the] strike period it will be business as usual [at HMRC], and [we are] dedicated to delivering a high standard of customer service'.
PCS general secretary Mark Serwotka, praised 'hardworking civil and public servants' and said that the 'Government has the opportunity to recognise that its own workforce is doubly disadvantaged by a punitive pay system' that is offering a rise 'just 13 or 25 pence above the national minimum wage'.
In January, members of HMRC staff threatened to disrupt self assessment deadline-filing day by striking over planned redundancies. The action was suspended when the department's management agreed to enter into talks with the PCS, which represents around 325,000 members in government departments, agencies, public bodies, and private companies.
