Taxi firms will receive grants of £10,000 if the SNP is re-elected next month.
Drivers will also be able to pocket a second £1500 payment in special Covid assistance as part of a “100 days” plan of immediate priorities to be unveiled today.
SNP Finance Secretary Kate Forbes said: “The last year has been extremely tough for taxi drivers and their families.
“They’ve truly gone the extra mile to provide a vital service for key workers and vulnerable individuals throughout the lockdown and beyond.”
The earnings of Scotland’s 37,000 taxi drivers and private licences have plummeted during the pandemic.
A demo was staged last year to protest about a lack of financial support and SNP ministers announced a £1500 grant for drivers to assist with fixed costs.
The Unite trade union has campaigned for £10,000 grants for each operator.
The commitments will be contained in a 'first 100 days' of Government document released by the SNP today.
Forbes said: "In the first 100 days of the new Parliament, a re-elected SNP government will provide a second payment of £1,500 for each taxi driver who previously received a Covid grant. We will also support taxi operator firms through these difficult times with grants of up to £10,000."
But Scottish Labour economy spokeswoman Monica Lennon accused the SNP of promising help they could have provided long ago.
She said: “I welcome the fact that Scottish Ministers have finally caught up to the urgent need to support the taxi trade.
“Scottish Labour has supported the taxi trade throughout the pandemic while SNP ministers shamefully ignored operators and drivers.
“The fact that the SNP government has committed, on the eve of an election, to do something that they have had the powers to do for months will be a bitter pill to swallow for many in the forgotten taxi trade.
Nicola Sturgeon said her party’s 100 days plan will provide urgent support for the NHS, boost the economy, create jobs and help children and young people.
