The chancellor is due to announce the autumn budget on 27 October.
Tanzer said that despite the more positive outlook for international travel, following the easing of restrictions, "it will take time for travel to get fully back on its feet".
Last month, Abta reportedly wrote to the chancellor urging him to use the budget to provide an update on the additional £1.5bn in targeted support for businesses which was announced earlier this year.
The body also urged local authorities to prioritise travel businesses for financial support under the Additional Restrictions Grant and called on Sunak to provide tailored financial support for the travel sector.
Tanzer said several of Abta’s Members have reported concerns with plans to increase corporation tax to 25% from 2023.
"It is important that a system is found that does not continue to disadvantage high street retailers, which are an important part of communities across the country," he said.
"The chancellor also needs to look at the role of APD in the industry’s recovery. Over the last year-and-a-half, we have seen cuts to VAT to benefit the domestic tourism sector, but these cuts have no impact on companies selling package holidays or on the outbound travel sector."
Tanzer also called on the government to work in partnership with the travel industry through the Jet Zero Council ahead of COP26.
