Your last chance to make a tax-deductible contribution this year to ProPublica is fast approaching. We hope you’ll seize it.

It’s been a year of great stories – but, even more important, it’s been a year of major impact from our journalism. That includes:

• What may be the beginning of the end to payments by pharmaceutical companies to prescribing doctors, as charted in our Dollars for Docs;
• Renewed moves toward information security after we revealed how the NSA undermined encryption standards;
• An IRS proposal to tighten the rules governing dark money campaign spending by so-called social welfare nonprofits on which we shined a light;
• Hundreds of millions of dollars in fines stemming from our Pulitzer Prize-winning reporting on deals by the financial firm Magnetar;
• Important first steps toward reforming Medicare Part D, where our reporting documented the waste of billions of taxpayer dollars and a systemic failure to detect fraud;
• The presidential commutation of the unjust sentence of Clarence Aaron, whose case we spotlighted.

If you value this sort of journalism, and the change it can bring, the time to show your support is now. ProPublica depends almost entirely on donations. Please do what you can today.
