The couple have signed a deal with the US streaming giant and will produce documentaries, shows and scripts.
It has been reported Meghan and Harry will receive an estimated $50 - $100 million between them.
They have now been asked to repay taxpayers money that was used to renovate their Frogmore Cottage home in Windsor.
The Duke and Duchess abandoned the pad after moving to California to live in a lush £14.7 million mansion.
After stepping down as senior members of the Royal Family, the couple pledged to pay back the huge sum in £18,000 monthly instalments, reports The Sun.
Former Lib Dem MP Norman Baker said the duo should start repaying the taxpayer's money immediately.
He told the Sun: "They should pay the taxpayer back immediately for Frogmore renovations rather than wait eleven years.
"They can both definitely afford it. They should either pay it when the Netflix money arrives or give up the cottage.
"Even the monthly amount they have set is willfully inadequate. I don't mind them having this deal with Netflix, good luck to them.
"But if they are going to do that then they have to make sure they are not benefiting from their royal status."
The outlet also reported Mr Baker, a member of the Privy Council and author added: "They still have their HRH status that means that the taxpayer is still paying for security guards walking round Frogmore and free travel back to the UK.
"Of course they should pay back Frogmore straight away - and also give up their HRH status.
"I don't mind them getting a deal as former HRHs but it surely goes against the terms of them stepping down if they get this deal using their HRH.
"The HRH title is a passport to state support. There needs to be a clean break."
