Instacart Shopper Didn't Pay Quarterly Taxes? What to Do Now (2025)
The short answer: if your Instacart didn't pay quarterly taxes, you'll likely owe an underpayment penalty on top of your tax bill — but it's fixable. File your return, report your earnings on Schedule C, pay what you can, and set up a plan for the rest. The penalty is usually smaller than people fear.
⏱ Your deadlines: estimated taxes are due four times a year — generally April 15, June 15, September 15, and January 15. If you missed one, make a payment as soon as you can: the underpayment penalty grows by the day, so a late payment is still cheaper than no payment. Your annual return is still due April 15.
Why you owe quarterly taxes as an Instacart shopper
When you shop and deliver for Instacart, you're an independent contractor, not an employee. No one withholds taxes from your batch payments. That means the IRS expects you to pay your own income tax and self-employment tax as you earn — in four estimated payments across the year, not all at once in April.
Self-employment tax alone is 15.3% of your net earnings (that's Social Security and Medicare, the part an employer would normally split with you). Add income tax on top, and a lot of new shoppers are shocked at the size of the bill. If your Instacart didn't pay quarterly taxes, you're not alone — this is the single most common mistake first-year gig workers make. For the full picture of how the system works, see our guide on how quarterly estimated taxes work.
What actually happens if you skip your quarterlies
Here's the calm truth: skipping estimated payments is not a crime, and it does not trigger an audit. What it triggers is the underpayment penalty — essentially interest the IRS charges for not paying on time. The longer the money stays unpaid, the more it grows. Here's the rough sequence:
- You miss a quarter. Nothing happens immediately — there's no notice for a missed estimate.
- You file your return. The IRS calculates an underpayment penalty (Form 2210) and adds it to your balance due.
- You owe a balance. If you can't pay it in full, the IRS sends a CP14 — the first bill — about 21 days later.
- You ignore the bill. Reminder notices follow, then a Notice of Intent to Levy, then a final notice with garnishment and levy power. This only happens if a balance sits unpaid for months.
The takeaway: missing a quarter is a minor, fixable problem. Letting an unpaid balance sit after you file is what turns into a real collection issue.
The penalty math, with a real example
People panic about the underpayment penalty because they imagine a huge fine. It's usually modest. The IRS charges a published interest rate on the amount you underpaid, counted for the days it was late. There's no flat fee and no doubling.
Say you earned $30,000 driving for Instacart and, after deducting mileage and expenses, your net profit was $22,000. Your combined income and self-employment tax might land around $4,000. If you paid nothing during the year, the underpayment penalty on that $4,000 — at a roughly 8% annual rate, spread across the quarters — typically comes out to somewhere around $150–$250. Annoying, but not the catastrophe most shoppers fear.
You can read the IRS's own rules on the underpayment of estimated tax penalty, and we break the numbers down further in didn't pay quarterlies — the penalty math.
Don't forget your deductions — they shrink the bill
Before you pay a dollar, make sure you're not overpaying. As an Instacart shopper you file a Schedule C, and your biggest write-off is almost always mileage. The standard mileage rate covers gas, wear, and maintenance for every business mile you drove — and for many shoppers that deduction alone cuts net profit by thousands.
Other common deductions include phone costs, hot bags and supplies, parking, and tolls. The lower your net profit, the lower both your income tax and your self-employment tax.

How to fix it, step by step
- Add up your Instacart income. Check your shopper app and any 1099-NEC or 1099-K you received. Report all of it, even if you didn't get a form.
- Total your deductions. Pull your mileage from the Instacart app or your own log, plus supplies and phone costs. This lowers your taxable profit.
- File your return on time. Even if you can't pay, file by the deadline. The failure-to-file penalty (5% per month) is ten times larger than the failure-to-pay penalty (0.5% per month).
- Pay what you can at IRS.gov/payments. Every dollar you pay now stops penalties and interest on that amount.
- Set up a plan for the rest. For balances under $50,000, you can usually arrange a payment plan online over up to 72 months. See how to set up an IRS payment plan online.
- Ask about penalty relief. If this is your first time owing, first-time penalty abatement may wipe out the late-payment penalty entirely.
- Set up next year now. Open a separate savings account and move 25–30% of each batch into it. Pay your four estimates and you'll never face this again.

Instacart quarterly tax questions, answered
What happens if I didn't pay quarterly taxes as an Instacart shopper?
You'll still file your tax return as normal, but you may owe an underpayment penalty on top of the tax. The penalty is essentially interest on what you should have paid each quarter. It's not a criminal issue and it's not a fine in the punishing sense — it's a charge for paying late, and it stops growing once you pay the balance.
How much is the penalty for not paying Instacart quarterly taxes?
There's no flat penalty. The IRS charges an underpayment penalty based on a published interest rate applied to the amount you underpaid for the days it was late. On a few thousand dollars of unpaid quarterlies, that often works out to a few hundred dollars — uncomfortable, but usually far smaller than people fear.
Can I still file my taxes if I never paid quarterlies?
Yes. Not paying quarterly estimates does not stop you from filing. You file your return, report your Instacart income and expenses on Schedule C, calculate the tax due, and pay what you can. Filing on time matters even if you can't pay the full balance, because the failure-to-file penalty is far larger than the failure-to-pay penalty.
What if I can't pay the Instacart taxes I owe?
File on time, then set up a payment arrangement. For balances under $50,000, a streamlined installment agreement lets you pay monthly over up to 72 months. If paying anything would cause real hardship, you may qualify for a pause in collection. You may also qualify for first-time penalty abatement if this is your first slip.
How do I avoid this next year as an Instacart shopper?
Set aside roughly 25–30% of your net Instacart earnings as you go, and pay estimated taxes four times a year — generally April 15, June 15, September 15, and January 15. Track your mileage, since the standard mileage deduction is usually the biggest write-off a shopper has and it lowers what you owe each quarter.
