As the partial shutdown of the federal government continues, workers are grappling with a looming worry: How will they pay their bills? While members of Congress and President Donald Trump remain at an impasse over funding for a border wall, about 800,000 federal employees are expected to be furloughed or working without pay. The U.S. Office of Personnel Management's verified Twitter account posted sample letters for affected federal workers to use with landlords and creditors as they request relief from any monthly payments during the stoppage. Tweet "This isn't the first time there's been a shutdown, and it won't be the last," said Marguerita M. Cheng, a certified financial planner and CEO of Blue Ocean Global Wealth in Gaithersburg, Maryland. She is keenly aware of this as her husband is a federal employee, but his agency — the Pension Benefit Guaranty Corp. — is remaining open.

Get in touch with the federal agency you work for to determine whether you are being furloughed and find out what resources are available. In some cases, federal credit unions are offering furlough relief loans to help affected workers remain afloat in the short-term. For instance, the Congressional Federal Credit Union has a relief line of credit with an initial rate of 0 percent for 60 days. After that, the rate on the remaining balance is 4 percent.

If you're about to be less flush heading into January, draw up your monthly budget and see what you can slash during the shutdown, said Cheng. If you have outstanding loans, including mortgages and student debt, be sure to contact your creditors to make them aware of your situation. "Most agencies also have a process in place for employees that they can use to reach out to creditors and landlords to ask for some relief," said Patrick Amey, a CFP at Aspyre Wealth Partners in Overland Park, Kansas.

Your cash sources

If you're unsure about your next paycheck, this is the time to turn to your emergency fund as a backstop. The standard rule of thumb is to maintain enough cash to cover three months to six months of expenses, said Bryan Beatty, a CFP and partner at Egan Berger & Weiner in Vienna, Virginia.

The next best alternative could be a zero-interest furlough loan or line of credit from a federal credit union, Beatty said. Remember, the zero-interest period runs for a limited amount of time — typically up to 60 days. If you already have a home equity line of credit open and available for draw-down, this might be a potential source of emergency funding. Consider that the average rate on a so-called HELOC is 5.64 percent, compared to the average credit card rate of 17.56 percent, according to Bankrate.com. The downside of taking out a HELOC is that the interest rates tend to be variable. Further, if you're using the line of credit for purposes other than renovating your home, you won't be able to deduct the interest on your taxes.
