The short answer
IRS TREAS 310 TAX REF is documented by the US Treasury as the company-name and entry-description fields for an IRS tax-refund ACH deposit. Check that your bank shows a credit and match it to your tax records. The documented label does not establish that an unexpected deposit belongs to you.
The Treasury documents these ACH fields
Treasury’s tax-refund FAQ says the ACH batch company name is IRS TREAS 310 and the entry description is TAX REF. It notes that 449 can appear instead of 310 for an offset refund. This is a federal-payment description, not a retail merchant or a subscription.
Confirm the direction of the actual transaction in the bank’s detail view. A plus sign in this page’s example does not establish how your bank has posted the entry. If your balance fell or the entry is a reversal, ask the bank to explain the ACH record instead of assuming that every line containing these characters is incoming money.

If the deposit differs from the filed refund
The IRS explains that refund adjustments and debt offsets can reduce a refund. Compare the deposit with your return, refund-status record and any notice. A difference is a reason to investigate those records; it is not proof of a particular debt or calculation error.
Keep the tax year separate from the bank posting date. An unexpected deposit may relate to a different return or adjustment, so ask which tax period the payment concerns before matching it to a current filing. Use official IRS and Treasury channels, rather than sending account or tax information to someone who contacts you about a surprise payment.

An erroneous direct deposit needs the bank’s ACH team
IRS Topic 161 instructs recipients of an erroneous direct-deposit refund to contact the bank’s ACH department to return it to the IRS and then contact the IRS to explain the return. Verify the situation through those official channels. Do not follow a stranger’s instructions to forward money or treat an unexplained payment as safe to spend.
Does TAXEIP mean the same thing as TAX REF?
This page documents the TAX REF tax-refund field. TAXEIP is retained as a historical lookup alias; it does not establish the same payment purpose or current eligibility.
Should I cancel an IRS TREAS 310 subscription?
This documented entry describes a federal tax-refund ACH deposit. There is no merchant-subscription cancellation route for that deposit; resolve an error with the bank’s ACH department and IRS.
