The "working visit" would not feature the pomp of a state visit and is likely to be part of an global tour by Mr Trump rather than a trip focused exclusively on the United Kingdom, according to the newspaper.
How will US President Donald Trump feel about being downgraded by the Queen?
The US President was originally invited on a full-blown state visit, which would include staying with the Queen in Buckingham Palace.
On Wednesday, Theresa May's office said she was not aware of plans for a "working visit", and said the position on the state visit had not changed.
Threats of mass protests and boycotts greeted news that Mrs May had extended the honour of a state visit to Mr Trump when she visited him in the White House in his first week in office.

Now it has been claimed that in early 2018 he will come to Britain anyway - but it will be a stripped-back trip without the trappings of an official state visit.
Sources have told the Evening Standard that no date has yet been fixed but the working visit is planned for early in 2018.
MPs from across the political aisle criticised the invitation at the time and John Bercow, the Commons Speaker, announced he would oppose an address to Parliament. Any encounter between the two would likely be frosty, after Trump publicly berated the mayor over his response to the London Bridge terror attack.
Thousands of people launched protests against the move, while more than a million people signed a petition to stop the trip from going ahead.
The Trump administration immediately dismissed the report, adding that the trip, expected next year, is still in the planning stages. Which I'm sure Theresa May is devastated about, seeing as how she seems to want to sort out a post-Brexit trade deal to replace all the trade we probably won't be doing with the EU.
