I hadn't even thought about business licenses! Is that something I need even if I'm just doing occasional art markets and some online sales? How do I find out what my local requirements are?

Even for occasional sales, most places require some form of business registration. It varies widely by location though. Start by checking your city's website for "business license" or "business registration" - most have simple online forms. Your county may also have requirements, especially if you're in an unincorporated area. The good thing is that for small creative businesses, the fees are usually pretty reasonable - mine was only $85 per year. The sales tax exemption on supplies makes it worth it alone. Also check if your state requires a general business registration or DBA ("doing business as") filing if you're operating under a business name rather than your personal name.

This is a really smart approach! How did you decide on those specific percentages though? Are those standard or did you customize based on your business?

Do these calculators take into account things like income phase-outs and other limitations? Sometimes I worry those online tools are oversimplified and miss the details.

Most of the good ones do factor in phase-outs and limitations! The Virginia one specifically asks for your income and filing status, then applies any phase-outs automatically. I've found them to be pretty accurate. The one limitation I've noticed is that some calculators don't handle multiple beneficiaries well. So if you're contributing to 529 plans for multiple people and your state allows credits for each, you might need to do some additional calculations yourself.

Great point! I misunderstood this for years and was excited about my state's "$5,000 529 benefit" until I realized it was a deduction, not a credit. At my tax rate that's only saving me about $250, not $5,000!

Exactly! The terminology makes a huge difference. I've found that states with deductions often allow much higher amounts ($10,000+ in some cases) while states with credits usually have lower limits but they're worth more dollar-for-dollar. It's also worth checking if your state allows carryforward of excess contributions. Some states let you carry forward contributions beyond the annual limit to get the deduction/credit in future years.

Do student loan interest and the lifetime learning credit work together too? Or is that a different thing entirely?

Student loan interest deduction and the Lifetime Learning Credit are separate tax benefits and yes, you can claim both in the same year if you qualify for both! The student loan interest deduction allows you to deduct up to $2,500 in interest paid on qualified student loans, and it's also an "above-the-line" deduction that you can take regardless of whether you itemize or take the standard deduction. So potentially, you could take the standard deduction, deduct student loan interest, AND claim the Lifetime Learning Credit all on the same return.

I used FreeTaxUSA last year and it handled my Lifetime Learning Credit perfectly fine without trying to upsell me. They have a totally free federal filing option that includes education credits. You only pay if you want state filing.

Does it cover more recent tax law changes like the TCJA and SECURE Act? I've found many tax books become outdated quickly when tax laws change.

It does cover TCJA changes pretty thoroughly, especially how they impact real estate investors with the new QBI deduction and business interest limitations. The SECURE Act coverage is more limited though, mainly focusing on the elimination of the stretch IRA and changes to RMD ages. The publisher does offer annual updates on their website that cover more recent changes, which helps keep the content relevant even as tax laws evolve. I've found this combination of the book plus the online updates works better than waiting for completely new editions.

I've used both. They're good for filling out forms but terrible for actually understanding the tax code. They just tell you what to do without explaining why or how things work together. Fine if you just want to file, useless if you want to learn and optimize.

Do you happen to know which states have different deadlines? I'm working on returns for clients in multiple states and now I'm worried...

I don't have a comprehensive list, but I know California strictly enforces their own cutoff time. New York and Illinois have occasionally had different timing requirements too, especially during extension periods. The safest approach is to check each state's department of revenue website directly. Most will have a specific notice about e-filing deadlines on their homepage this time of year. If you can't find clear information, finish those multi-state returns at least 24 hours before the federal deadline to be safe.

YES! This happened to me with Drake last year. The system was crawling and I nearly missed the deadline. This year I'm finishing everything by noon on the final day just to avoid the stress.
