It’s that time of year again—tax season. If you’re a Philly business owner with a net operating loss, you might be wondering how to use it in future tax years to reduce your tax liability. The good news is that the City lets you carry forward business losses incurred in 2022 and after, for 20 years.

If you had a loss in 2024 and want to carry it forward, you can do it on the Philadelphia Tax Center. The site lets you document losses and carry them forward automatically, from different tax years or periods. Read on to find out more.

Loss carry forwards

Businesses in Philadelphia can use net operating losses (NOL) incurred in one tax year to offset future taxable net income.

For example, if you incurred a $100,000 loss in 2023, you could carry that loss forward to offset taxable net income in 2024. If you have a taxable net income of $50,000 in 2024, you could use the loss from 2023 to offset the 2024 taxable net income. You’ll still have $50,000 of the original loss to carry forward to offset future years’ taxable income.

Continuing the same example, if you make $75,000 in 2025, you can offset $50,000 of that taxable income with the unused loss from 2023. This reduces your taxable net income for 2025 to $25,000.

In essence, a loss carry forward lets you use today’s loss to offset future years’ taxable net income, reducing your tax liability in those years. Plus, a taxpayer’s income and losses are smoothed out when past losses are deducted from future profits. It reduces the tax gap between businesses with stable profits and ones with fluctuating profits.

Here is the same example from above in a different way:

Year Profit or loss for the year How much Loss Carry Forward is left?
2023 – incurred a loss ($100,000) ($100,000)
2024 – had taxable net income $50,000 – $50,000 = $0 taxable income $50,000
2025 – had taxable net income $75,000 – $50,000 = $25,000 taxable income $0

Document your carry forwards

It’s important to keep a record of your loss carry forwards. The best way to do this is to file a complete Business Income & Receipts Tax (BIRT) return. Even if you don’t have a BIRT filing requirement, you should still file a complete return if you have a loss you want to carry forward. This is the best way to document your losses. It’s also the only way we can have a record of them in our system.
