The levy would bring in millions of pounds in revenues and town hall chiefs insist it will help meet the soaring costs which comes with the mass influx of visitors that cities like Edinburgh face throughout the year.
The Scottish capital is already consulting on such a scheme, which city fathers say could raise £11 million a year with charges of £1 to £2 a night.
Hospitality industry leaders have been sceptical about the idea, but local authority body Cosla stepped up its plans with the launch of a new report at Edinburgh’s City Arts Centre yesterday.
The Scottish Government has so far rejected calls to introduce the legislation at Holyrood, which would be needed to introduce such a measure.
But Cosla’s resources spokeswoman Gail Macgregor, an Conservative councillor, revealed she has held talks with finance secretary Derek Mackay about the prospect of Transient Visitor Tax (TVT).
She claimed his attitude was softening.
“I think he’s a little bit more open-minded than he was before,” Cllr Macgregor said.
She added that Labour and the Liberal Democrats were on board and the Tories were also sympathetic to the idea of councils being able to raise their own revenues.
Such tourists taxes are common in other major European cities like Amsterdam, Brussels and Rome, but Scottish ministers fear tourists already pay far higher rates of VAT in the UK and an additional tourist tax may drive away visitors and hit the accommodation industry.
Hospitality chiefs have been vocal critics of the plan, but Cosla president Alison Evison said she was aware of the anxieties.
But she added: “No local authority would take an action that would be damaging to their area or local economy.”
She said the money received by councils in the last local government settlement was “not the money that we required”, but cash raised by tourist tax would be additional, not a replacement.
Ms Evison said: “We want to be fiscally empowered to raise money locally, which can then be spent on delivering local priorities.
“Transient visitor tax represents a key step towards local financial empowerment through local devolution.”
Various options for rates are outlined, including flat rates, a percentage of accommodation or a progressive tax based on star ratings.
A Scottish Government said there were “no plans” to introduce legislation for a tourism tax amid concerns over existing VAT levels.
