SNP Westminster group leader Angus Robertson was among 13 MPs who had their credit cards blocked over unpaid expenses.
Mr Robertson, the party’s deputy leader Stewart Hosie, Angela Crawley, Pete Wishart and Angus McNeil were subject to action by the Independent Parliamentary Standards Authority (Ipsa).
All of the party’s representatives have since repaid sums ranging from £33 to £3,446 in full.
Glasgow East MP Natalie McGarry, who has been suspended from the SNP amid allegations relating to missing donations, owed £2,270 when her card was blocked on January 25.
She had £2,370 outstanding as of February 23. Her office blamed a “mix-up” and said the situation had now been “rectified”.
Democratic Unionist Party (DUP) MP Ian Paisley was £27,766 in the red when his card was stopped last November. The deficit was £20,337 by last month.
Shadow work and pensions secretary Owen Smith, former minister Liam Byrne and backbencher Simon Danczuk are on the list, having owed £953, £1,189 and £595 respectively. The amounts have all since been cleared.
Labour’s former policy chief Jon Cruddas was subject to action before Christmas over £2,967 of expenses. Mr Cruddas said he exceeded the printing and postage budget for last year and had now agreed to settle the overspend by April 1.
Tory backbencher John Stevenson had his card blocked in December over £608 of debt but has since settled the amount. Fellow Conservative David Morris’ card was suspended the same month, when he owed £12,240.
He said Ipsa had initially failed to process the transactions properly and later discovered an overspend in office costs of nearly £5,000.
“This overspend happened due to numerous admitted errors by Ipsa with their system, but under the scheme any budget overspends must be personally reimbursed by the member from their own pocket,” he said.
“This issue has now been resolved and the amount agreed as owed is being paid back by myself from my own pocket.
“I must stress that these expenses claimed for were all permissible claims and were legitimate office costs incurred by carrying out my parliamentary duties to my constituents.”
Ms McGarry’s office said her card was operational, adding: “There was a mix-up in the payment of the deposit for accommodation, but this has since been rectified, and Ipsa are satisfied with the repayment.”
Ipsa issues MPs with credit cards to pay for a variety of items such as travel, accommodation and stationery.
The politicians then have to prove the spending was allowable within a month or they build up debts. The sums are recouped by suspending the cards and not paying out valid expenses claims, or in instalments from the MP’s salary.
The latest details date from the end of June, when a previous disclosure sparked a furious row between work and pensions secretary Iain Duncan Smith and Ipsa about whether or not his card had been suspended over a £1,000 debt.
Some of the new cases involved disputed claims, with Western Isles MP Angus MacNeil building up a £950 tab after charging a series of hotel bills for more than £250 a night.
He insisted the rooms were the cheapest available but has now repaid the difference above Ipsa’s £150 a night maximum rate.
An SNP spokesman said: “By its very nature the operation of the expenses system means that Ipsa often owes outstanding amounts to MPs and MPs often owe outstanding amounts to Ipsa. Outstanding amounts are then repaid.”
The watchdog was challenged about the credit card rules by SNP MP Pete Wishart at a hearing of the speaker’s committee that oversees it this week.
The Perth and North Perthshire complained that having to provide evidence for spending within a month could be “burdensome” and highlighted that new SNP MPs had their cards suspended.
“Ipsa had made such a fantastic impression on our new groups of MPs when they were newly elected,” he said. “There was goodwill towards Ipsa. Totally gone after that.”
The watchdog’s chief executive Marcial Boo responded: “I am obviously very sorry that it has cost a lot of goodwill. But it is part of the role that we have to make sure that payments that we make are supported by evidence. As soon as MPs provide us with that evidence the card is turned back on again.”
He added: “We cannot allow ourselves to be in a position where an MP is making thousands of pounds of payments on a card and failing to give us evidence to support that payment, without taking any action.”
