FROM payment INNER JOIN income,bank_dep

You can have more tables in FROM, like: FROM payment,income,bank_dep, but you can't have other than one single table after JOIN, and you have two. And you never can have an operation like a=b=c, but you have You need to split the statement across multiple joins:
SELECT payment.indate,payment.opening_balance,payment.purpose,payment.amount,income.indate,income.opening_balance,income.purpose,income.amount,bank_dep.indate,bank_dep.balance_opening,,bank_dep.amount 
FROM (payment 
INNER JOIN income ON payment.indate=income.indate)
INNER JOIN bank_dep ON income.indate=bank_dep.indate

it gives an error "syntax error(missing operator) in query expression 'payment.indate=income.indate INNER JOIN bank_dep on income.indate=bank_dep.indate"

Sorry, Access is non-standard, it requires some parenthesis. See updated query.
