Taxman's concession on big bills
A new concession will mean many people facing the highest demands for back-tax will not face interest payments.
Those given time to pay more than £2,000 in underpaid tax will now have interest waived - in line with those with smaller demands, MPs were told.
The Permanent Secretary for Tax, Dave Hartnett, told the Treasury Committee that the authorities "could have done better" to prepare people for bills.
More than two million people underpaid income tax in the past two tax years.
This was the result of errors in their Pay As You Earn (PAYE) tax code.
About 900,000 taxpayers will not have to pay anything after the government raised the write-off threshold from £50 to £300, a concession costing the Treasury £160m.
This left 1.4 million people owing about £2bn, or £1,428 each on average.
