10 Tips for Last Minute Tax Filers

When clients call me in a panic the week before filing, the goal is simple; get filed accurately, avoid penalties where possible, and clean things up later. Here are 10 practical, real-world tips I give last-minute tax filers:

1. File something on time

Even if it’s not perfect, filing on time avoids the failure-to-file penalty, which is much steeper than the failure-to-pay penalty. You can always amend later.

2. If you can’t file, submit an extension immediately

File IRS Form 4868.
This gives you until October, but keep in mind; it’s an extension to file, not to pay.

3. Estimate and pay what you can

The Internal Revenue Service is far more forgiving if you’ve made a good-faith payment. Even partial payments reduce penalties and interest.

4. Focus on income first

Make sure all income is accounted for; W-2s, 1099s, bank interest, PayPal, Stripe, etc. Missing income is one of the biggest triggers for IRS notices.

5. Don’t chase every deduction right now

This is where people get stuck. Get the return filed first. If needed, your accountant can refine deductions later with an amended return.

6. Use prior year returns as a roadmap

Last year’s return shows you what to look for; income sources, deductions, credits. It’s one of the fastest ways to avoid missing something obvious.

7. Double-check bank and credit card totals

If your books aren’t clean, at least review totals. A quick reconciliation pass can catch major errors before filing.

8. Watch out for duplicate or missing 1099s

Platforms like PayPal, Stripe, and Square can overlap. Make sure you’re not reporting the same income twice, or worse, missing it entirely.

9. E-file if at all possible

E-filing is faster, more accurate, and gives confirmation. Paper filing this late increases the risk of delays and processing issues.

10. Know when to call in help

If your books are messy, multiple income streams are involved, or you’re behind more than one year, this is where a QuickBooks ProAdvisor steps in. A professional can get you filed quickly and set you up so next year isn’t a repeat of this situation.

The Biggest Mistake is Doing Nothing.

Last-minute filing isn’t ideal, but it’s very fixable. The biggest mistake I see is people freezing up and doing nothing. Filing imperfectly on time is almost always better than filing perfectly late.
