Common problems we fix:

If any of this sounds familiar, you’re not alone:

  • “I don’t know what I should be paying quarterly.”

  • “My books are behind and I’m stressed.”

  • “I’m making more money but somehow paying more tax than ever.”

  • “Someone told me to become an S-Corp — should I?”

  • “I’m not sure what counts as a write-off.”

Small Business Taxes

  • Does Keystone Tax work with small business owners?

    Yes. Keystone Tax works with small business owners on tax preparation and tax planning, including Schedule C businesses, deductions, S-Corp considerations, and quarterly estimated taxes.

  • Does Keystone Tax prepare taxes for LLCs and S-Corporations?

    Keystone Tax works with small business owners, including businesses that operate under different entity structures. Because filing requirements vary depending on how a business is structured and taxed, we recommend discussing your specific situation with our team.

  • Do self-employed business owners need to make quarterly estimated tax payments?

    Many self-employed individuals need to make estimated tax payments during the year because income taxes are generally not automatically withheld from self-employment income. Estimated payments may need to be adjusted as income changes throughout the year.

  • Can Keystone Tax help calculate quarterly estimated taxes?

    Yes. Quarterly estimated tax planning is one of the areas Keystone Tax helps small business owners address. Instead of waiting until filing season, planning throughout the year can help business owners better anticipate their tax obligations.

  • When should a small business owner hire a tax professional?

    A business owner may benefit from professional tax guidance when starting a business, choosing or changing an entity structure, hiring employees or contractors, making estimated tax payments, evaluating deductions, or when business income becomes more complex.
