HM Treasury intends to give tax relief worth hundreds of millions of pounds to those earning over £110,000, it is being reported.
HM Treasury has confirmed that the government will hold its Budget on 11 March.
The government should consider making auto-enrolment (AE) minimum contributions compulsory and removing tax-relief from this sum, Baroness Ros Altmann says.
The Net Pay Action Group (NPAG) is urging the government to deliver on its manifesto pledge to review unfair tax rules in pensions.
The government has rejected the Treasury Committee's call for fundamental and incremental changes to pensions tax relief, noting there is "no clear consensus".
