Track side income for the 1099-K threshold with an AI agent

8 min read
Direct answer: For 2026, payment apps and online marketplaces generally must send a Form 1099-K only if you received more than $20,000 across more than 200 transactions for goods or services, per the One Big Beautiful Bill Act. Card processors have no minimum. Below the threshold, the income is still taxable. An agent connected to your bank can total payouts by platform each month so you know where you stand.

The 1099-K threshold for 2026

Form 1099-K reports payments you received through payment cards and third-party networks. For payment apps and online marketplaces (third-party settlement organizations), the One Big Beautiful Bill Act, signed in July 2025, retroactively reinstated the older threshold. Under the IRS guidance:

  • Payment apps and marketplaces generally send a 1099-K when payments for goods or services exceed $20,000 and the number of transactions exceeds 200 in a calendar year. They may send one for less.
  • Payment card processors (if you take card payments directly) send a 1099-K no matter how many payments or how much.
  • The form does not decide taxability. You generally must report income from goods or services whether or not you receive a 1099-K.

This article explains how to organize your records. It is not tax advice. Selling personal items at a loss, hobby income, and business income are treated differently. Talk to a tax professional (a CPA or enrolled agent) about your situation, especially if you are close to the threshold or have income across several platforms.

What your bank sees (and does not)

Your bank sees payouts: the deposits a platform sends you, usually after fees and refunds, often batching many sales into one transfer. The 1099-K reports gross payments before fees, counted per transaction. So:

  • Your bank deposits will usually total less than the gross figure on a 1099-K.
  • Your bank deposit count is not your transaction count.

Use bank data for what it is good at: a complete, cross-platform view of money that arrived, available any day of the year. Use each platform's sales report for the gross and the count.

1. Find every side-income payout

Connect the accounts where payouts land at bankbridge.money and add BankBridge to your agent (Claude, ChatGPT, Claude Code). Then:

“List every deposit into my accounts this year that is not my paycheck and not a transfer between my own accounts. Group them by source: marketplaces, payment apps, payment processors, and anything else. Show the total and count per source.”

The agent pulls deposits with list_transactions (money in has a negative amount) and narrows by source with search_transactions. Review the “anything else” group by hand.

2. Separate personal transfers

Payment apps carry both kinds of money: a customer paying for a commission and a friend paying back concert tickets. Only the first is side income. Tell the agent the difference:

“Incoming payment-app transfers from Alex, Mom, and Jordan are personal. Exclude them. Everything else from payment apps is customer income.”

Also label personal payments correctly inside the app when you send or receive them; the app's own records are what drive its 1099-K.

3. Keep a running total

Once a month:

“Update my side-income tracker: payouts by platform this month and year to date, excluding the personal senders on my list. Flag any platform where year-to-date payouts are over $15,000 so I can check its gross sales report.”
Side income, 2026 year to date (bank payouts, net of fees)

Source                Sep      YTD      Deposits
Marketplace A      $1,240   $9,860         38
Payment processor    $610   $5,115         22
Payment app (biz)    $380   $2,740         51
Total              $2,230  $17,715        111

Flag: Marketplace A payouts are net; check its gross sales
report against the $20,000 / 200-transaction threshold.

Pair this with quarterly estimated taxes from real bank deposits so you set money aside as the income arrives.

4. Prepare for tax time

  • Export the year. In Claude Code, /tax-prep 2026 writes a full transaction CSV and a category summary.
  • Pull expenses too. Fees, supplies, shipping, and software for the side business are on your cards. Ask the agent to list them by category.
  • Reconcile against any 1099-K.When a form arrives, ask the agent to compare it with the platform's payouts. The gap should be explained by fees, refunds, and timing.
  • Bring it to a professional. Hand your tax preparer the tracker, the CSV, and any 1099-Ks.

FAQ

What is the 1099-K threshold for 2026?

For third-party settlement organizations such as payment apps and online marketplaces, more than $20,000 in gross payments for goods or services and more than 200 transactions in the calendar year. The One Big Beautiful Bill Act restored this threshold retroactively. Platforms may still send a 1099-K for lower amounts, and card processors send one regardless of amount.

If I stay under the threshold, do I owe tax on side income?

The threshold only decides whether a platform files a 1099-K. It does not decide whether income is taxable. The IRS says you generally must report income from selling goods or providing services whether or not you receive a form. A tax professional can tell you how it applies to you.

Can my agent count my 200 transactions?

Not from bank data alone. Platforms usually pay out in batches, so one bank deposit can cover many sales. The agent can count and total payouts; use your platform's sales report for the gross amount and transaction count the 1099-K is based on.

Do friends paying me back count toward the 1099-K?

Payments between friends and family that are not for goods or services are not reportable on a 1099-K. Payment apps rely on how payments are labeled, so tag personal payments correctly in the app, and tell your agent which senders are personal so it excludes them from your side-income total.

Does my state have a different threshold?

Some states set their own, lower reporting thresholds for state purposes. Check your state's revenue department or ask your tax professional.

Can BankBridge file or calculate my taxes?

No. BankBridge gives your agent read-only access to your transactions. The agent can organize and total income and expenses for you to take to a tax professional or tax software. It is not tax advice.
