While only 9% of Internal Revenue Service employees — roughly 8,750 out of nearly 95,000 workers — are currently working, the underlying tax law remains in effect.

That means “all taxpayers should continue to meet their tax obligations,” according to the IRS’s website.

Need an IRS employee to answer a question, though? “That’s where there will be challenges,” said Edward Karl, a certified public accountant and vice president of taxation for the American Institute of CPAs. Not only are customer service agents unavailable, but the Taxpayer Advocate Service, which fields consumer complaints, is also closed.

Here are some other things you need to know about your taxes and the IRS during the shutdown:

Will I still have to meet the October 15 deadline?

Yes. Regular filing deadlines will remain in effect during the shutdown. So anyone who requested an extension on their taxes last spring should still file their returns by October 15.

Around 6 million individual returns are expected. “A lot of them are finished up in these last couple of weeks,” Karl said.

The IRS is urging individuals and businesses to file their tax returns electronically because those returns are usually processed automatically. Paper returns will not be processed until full government operations resume. Yet, they still must be postmarked by October 15 to be considered filed on time.

That means I’ll get the tax refund I’ve been waiting for, right?

Wrong. While tax returns and payments are still expected to be filed during the shutdown, refunds won’t be issued until operations return to normal, the IRS said.

What if I need help with my taxes?

Sorry. Live telephone customer service agents are among the tens of thousands of IRS workers that have been furloughed. The IRS’s walk-in taxpayer assistance centers are also closed, as well as the Taxpayer Advocate Service, which fields consumers complaints and offers free tax help.

You’re not entirely out of luck, though. The IRS’s automated assistance line is still open at (800) 829-1040, and private tax preparers should be able to help you navigate the shutdown.
