Our Story

Why we built Tributary.

By any conventional metric, I was doing well. Years of work and investing had built income from a few different directions, and it had grown into something I was proud of.

But every quarter, the same thing happened: I'd realize a tax payment was due, scramble to come up with the number, and never feel sure it was right. It was always reactive, always last-minute, always a guess.

Here's the thing I wish I'd understood sooner: this isn't just a problem for people with big portfolios. If you expect to owe $1,000 or morethat isn't already covered by withholding, the IRS generally expects you to pay throughout the year, not just in April. That's a low bar, and it catches a lot of business owners, freelancers, and investors off guard.

I tried spreadsheets, but they were static, and income isn't. So, I brought together a team, including a world-class engineer, and we built Tributary to take the guesswork out of forecasting income and taxes.

Whether your money comes from a portfolio, a business, a side hustle, or all of the above, Tributary lets you forecast your income as it actually happens and see a clear picture of what you'll owe. Avoid IRS penalties, overpayments, and surprise interest charges, and stay in control of your taxes all year long.
