How should a tax firm monitor and protect its EFIN?
At the exam level, focus on application accuracy, transmission monitoring, and credential protection. The firm should keep the e-file application current, monitor accepted-return totals, protect e-services credentials, and contact the IRS e-help desk if the EFIN appears compromised.
Can my firm e-file a return it did not prepare?
IRS guidance recognizes that a firm may e-file a return it did not prepare if the firm receives the return directly from the taxpayer and follows the e-file provider rules. That is different from letting another preparer or suspended firm use your EFIN as a workaround.
What is the difference between a PTIN and an EFIN?
A PTIN is the individual paid preparer identifier. An EFIN is tied to an approved IRS e-file provider application. The EFIN is not a substitute for the preparer PTIN, and the PTIN is not a substitute for e-file provider authorization.
Can another preparer use my firm's EFIN?
No, the PTIN alone is not enough. A PTIN identifies an individual paid preparer. An EFIN identifies the authorized IRS e-file provider whose application, suitability, principals, responsible officials, and filing activity are tied to the electronic submission.
Why does an IP PIN return still reject?
The return can still reject if the PIN is missing, stale, entered for the wrong person, or required for another person on the return. An IP PIN is generated annually. If the taxpayer uses an older number, the e-file system may reject the return.
Can health insurance alone make someone a dependent?
No. Health insurance coverage may be one support fact, but it does not by itself make someone a dependent. A dependent must be a qualifying child or a qualifying relative.
Does an amended dependent return unlock e-file?
Not immediately. An amended return can correct the first filer tax position, but the IRS still has to process the amendment. The duplicate SSN conflict may continue to affect e-file validation while that happens.
Can parents e-file after a dependent filed first?
Sometimes, but only after confirming that the parents are actually entitled to claim the dependent. For Tax Year 2024 and later current-year returns, the IRS provides an e-file path in a duplicate-dependent situation when the primary taxpayer has a current calendar-year IP PIN.
Why does my rideshare business still owe tax after I claimed mileage?
Because mileage is a deduction, not a tax eraser. A rideshare driver can have valid deductions and still show meaningful net profit. The exam trap is assuming a large deduction means the return should show no tax due.
Does electing S corporation status automatically save self-employment tax?
No. An S corporation election can change how owner compensation and distributions are analyzed, but it is not a universal shortcut. You still have to think about reasonable compensation, payroll costs, and compliance.
How do I tell whether a side activity is a business or a hobby?
Start with profit motive. A side activity can have losses and still be a business, but the facts should show the taxpayer is trying to make money rather than simply offset the cost of a personal pastime.
Can an LLC deduct an owner's personal car just because the business paid for it?
No. The payment source does not control the deduction. The better question is whether the vehicle was used for business and, if so, how much of that use was business rather than personal. An LLC can own the car, but that does not convert family commuting into deductible use.
What if a partnership owner receives both a profit share and service payments?
Split the amounts before you solve the tax issue. The clean exam move is to treat the service-linked amount as separate from the distributive share. Candidates lose points when they lump both numbers together and mark one universal answer.
Can an active owner use limited partner status to avoid self-employment tax?
Not by slogan alone. An active owner cannot simply point to a limited-partner label and assume every item escapes self-employment tax. The exam wants you to slow down and classify the facts.
How should I treat guaranteed payments to a limited partner?
Start by remembering that guaranteed payments are not just another name for distributive share. If the partnership pays a fixed amount because the partner manages staff, negotiates contracts, or supervises production, the exam is pointing you toward a service-payment analysis.
Does a limited partner's distributive share always avoid self-employment tax?
Not automatically. The safest answer is that a limited-partner fact pattern may support excluding the distributive share from self-employment tax, but that does not mean every dollar received from the partnership gets the same treatment.
When should I push back on an IRS-generated refund from a CP12 adjustment?
Push back when the IRS-created refund depends on an adjustment you know is substantively wrong. A favorable notice is still a notice, not a guarantee that the IRS analyzed the return correctly.
How do I handle an IRS refund check that clearly belongs to someone else?
Do not treat the check like free cash and do not assume one phone call resolves the account. A mistaken refund often means the IRS posted a payment or credit to the wrong taxpayer account and the automated notice stream has not caught up.
What should I do if a CP14 says I did not pay but my account shows zero?
Treat it as a reconciliation problem first, not as proof that you still owe the tax. If the IRS account already shows 0, the most likely issue is that the notice cycle was triggered before the payment fully posted.
Should I amend immediately after a CP2000 missing-basis notice?
Usually no. A CP2000 is typically a proposed change based on data the IRS matched against the return, often without full basis information. If the problem is missing basis on securities sold, the stronger first move is to respond to the notice with the basis records and the corrected gain computation.
