COBOL outside IR35 jobs
An outside IR35 COBOL job is a contract the client says sits beyond the off-payroll rules, so you can invoice through your own limited company. The work itself is still mainframe estates in insurance and banking that still settle the day's business. The status is a tax determination, not a description of the skill.

What outside IR35 means on a COBOL contract
Outside IR35 means the engagement is treated as a business-to-business supply of COBOL, not as employment in all but name. You invoice your company rate. You do not have the client's holiday, pension or employment rights, and you carry the admin of a limited company. That trade is why contractors filter for outside roles first.
The client, or the agency where the client is a small company, makes the determination and should be able to show it. A sentence in an advert is a signal. It is not the status determination statement. How IR35 status is decided walks through what you can ask for.
How often COBOL roles are outside
Outside IR35 is common on COBOL delivery contracts, particularly where you use your own equipment, control your own method and can send a substitute. Staff-augmentation inside a bank or a government department is still frequently marked inside, sometimes as a blanket decision. Read the status on the advert and then read the working practices, because the two do not always agree.
Banks, product companies, consultancies and the public-sector programmes that still build their own software do not share one policy. Two COBOL adverts in the same week can land on opposite sides because the working practices differ, or because one client blankets a programme and the other does not. Filter the claim, then confirm it.
What to check before you accept
Look at substitution, control and whether you are part and parcel of the organisation. A COBOL contractor who is told the hours, the method and the laptop, and who cannot send someone else, is harder to defend as outside even if the advert says it. The inside and outside IR35 guide is the short version of that difference.
Price the rate on both sides with the IR35 calculator. A move from outside to inside halfway through a renewal is a pay cut unless the day rate moves with it. COBOL day rates has the band clients are advertising.
Where to find them
Outside IR35 jobs is every live contract on the board that states outside, across every skill. COBOL contract jobs is the wider market, including inside and unstated roles. The apply link on each job is for members, so the original advert is not sitting open on the public page.
Geography follows the rest of the COBOL market: London, Manchester, Edinburgh, Bristol and remote. Remote outside IR35 roles exist and are competed for harder than a hybrid seat in one city.
Live roles on the board
Nothing in this cut of the market is on the public board right now. New contracts land every hour, and the full COBOL list is the place to watch.
