Where the slackers are. Or, the taxman cometh.

Filing day is just one week away.

When it comes to taxes, plenty of people adhere to Ellen DeGeneres' mantra: "Procrastinate now. Don't put it off." Of course some of us are better at that than others–like the folks in San Francisco.

Tax-prep software giant TurboTax released its eighth annual list of top procrastinating cities last week, and the city by the bay snagged the dubious top honor this year, up from fifth place in 2008. Houston, New York, Chicago and San Diego rounded out the top five slacker cities.

There's one week to go, and if you're starting to sweat because the clock is ticking, keep these things in mind:

• You have until April 15 to contribute to an IRA and trim your tax bill.
• You can find get free federal income tax preparation and electronic filing through the IRS' Free File program.
• You can still slash your 2008 tax bill through new credits and breaks, if you've had stock losses, and more. For details, see MONEY's gallery full of tips for 2008 by my colleague, Carolyn Bigda.
