DoorDash. Uber. Instacart. You cover the gas, the gear, and the tires. Existing tax software wasn't built for people with dozens of income sources. Sourdough was.
Link your bank and gig apps. Sourdough reads every transaction, finds every deduction, and keeps itself up to date as your income changes throughout the year.
Our AI shows you the IRS rule behind each deduction — not just the amount. Know exactly what you're claiming and why the IRS accepts it.
No surprises. No upsells. $99 covers your federal return and your state return. California first — more states coming as we build them out.
Every transaction, mapped to the IRS rule that makes it deductible. This is what it looks like when software actually understands gig work.
