I insisted on doing my own taxes for years — until a CPA saved me $4,700

  • For years I did my own federal and state taxes using TurboTax – but that’s changing for Tax Day 2020.
  • Last year, I was hit with a much higher tax bill, but figured it was because my income had increased.
  • When I spoke to a CPA about this year’s taxes, he reviewed my 2018 taxes and found that I had paid $US4,700 too much in state tax.
  • He filed an amendment, I got a refund, and I vowed never to do my own taxes again.

For years, I have filed my own taxes. As a child I watched my mum with stacks of receipts spread across the kitchen table, typing in numbers to file taxes for the interior painting business that she and my dad owned.

When I began filing my own taxes, it made sense to follow her lead and do them myself, rather than hiring a professional. I signed up for TurboTax, the same e-filing program that my mum used, and filed without any trouble for years.

That is, until I was hit with a nearly $US5,000 tax bill that was wholly unexpected, and, it turns out, wrong. Here’s what happened, and why I’ll be hiring a tax professional in 2020 and beyond.

An unexpected bill

I used to roll my eyes a bit when people stressed about filing taxes. Doing my own taxes was straightforward, I thought, even though I am self-employed with a sole-proprietorship business.

I put in my income and expenses, and TurboTax would generate a Schedule C with my self-employment income. I filed online and digitally paid whatever I owed. Eventually, I started paying federal tax quarterly, as my business grew. Simple.

Then, last year, I got a surprise. I live in New Hampshire, a state with no personal income tax. And yet, TurboTax calculated that I owed $US4,700 in state business tax from my work as a writer. I was frantic.

I had paid federal taxes quarterly and did not have money saved for this added expense. And yet, when I googled and read up on tax law, it all sounded legit: Unbeknownst to me, New Hampshire has an 8.2% business profits tax that kicks in when the gross business income exceeds $US50,000, a threshold I crossed last year.

I knew I should talk to a tax professional, but it was high tax season, and everyone was booked weeks out. Plus, my husband and I were trying to buy a new house, so I wanted our latest tax returns wrapped up as soon as possible.

From my small amount of research the bill seemed in line with state law, so I assumed TurboTax was correct. I submitted a check for $US1,200 to the state and set up a payment plan of $US700 a month until the remainder was paid off.

Professional insight

Although I was able to make those monthly payments, I couldn’t afford to pay my back tax and still save for my 2019 tax bill. I was stressed about falling into a cycle of being behind on taxes.

To complicate things even more, my husband and I had started renting out our home, and I didn’t know what impact that would have on our taxes.

I decided to get ahead of the game. In September I started calling tax professionals, or CPAs (Certified Professional Accountants). One droned on, asking me few questions. The second person I talked to politely interrupted me when I said I owed money to the state.

“You shouldn’t have owed anything,” he said firmly. “Was your bill around $US4,700?”

I was impressed that he knew the figure without me mentioning it. He explained that while the state does tax businesses, there is a $US75,000 reasonable compensation deduction. Since I earned less than $US75,000 in profit, I didn’t owe anything.

I was incredibly relieved. Within two hours of our phone call the CPA had filed an amended return. His fee was $US125. The next week, I received a $US3,000 check from the state, a refund for everything I had paid thus far. I literally skipped up my driveway with the check in hand, feeling like a kid on Christmas.

The refund was great, but the real relief was knowing I wouldn’t owe a similar amount in 2019 and future years.

Admitting that I need help

Since the CPA found such a large mistake on my 2018 taxes, I asked him to review 2016 and 2017 as well. It turns out, I was doing everything right those years. My gut feeling that filing taxes wasn’t too complicated was, on some level, correct.

Still, I realised that my taxes had become more complicated over time. This year my writing business will gross about $US100,000, so I likely will owe state tax. Then, there’s the income I’ll generate from my rental. Filing my taxes is no longer as simple as plugging in a few numbers.

The CPA charges hourly, and he estimates it will cost about $US500 to do my taxes this year. Considering I spent about $US200 on TurboTax’s self-employed program last year, the CPA’s rate seems entirely reasonable.

As a professional, I’ve realised where my limits are, and from now on I will be delegating tax preparation to other professionals who I can trust.
