Lender TSB is offering to pay the 1% stamp duty charge for mortgage customers buying a home costing between £125,001 and £250,000.
This could give buyers a one-off payment of up to £2,500.
The offer follows new research from TSB showing that more than one in 10 aspiring homeowners worry about their ability to pay stamp duty.
It is a valuable incentive with the average homebuyer now spending £1,650 on stamp duty, according to TSB calculations based on Land Registry figures.
In January 2013 alone, 40,000 people spent a total of £70 million in stamp duty.
The new offer applies to the bank's mortgage products, which boast interest rates starting from just 2.84%.
Many of TSB's mortgage products come without an application or product fee as well, bringing further upfront savings.
TSB is also offering help for customers whose properties costs less than the £125,000 stamp duty threshold, or more than the £250,000 threshold.
It will offer them £500 cashback towards the associated costs of buying a property, such as stamp duty, surveying and removal fees.
TSB managing director Ian Ramsden said: “With more than one in 10 customers worried about shelling out for stamp duty, it is clearly a significant upfront cost for first-time buyers and homemovers alike.
“This offer could save TSB customers up to £2,500, enabling homebuyers across Britain to spend more on what matters most to them when moving house.
"By putting this money back into its customers’ pockets, TSB is helping fuel local economies.”
