You can fill out the correct New York amended return manually rather than buy another service, but your exact refund must be calculated from your filed return and corrected tax records.
“I filed my NY State Tax Return through Sprintax and overpaid. I need to file an IT-201-X amendment, but Sprintax keeps calculating the wrong amount and I don't know the exact figure. Should I use another third-party service to calculate the correct amount, or how do I fill the form manually?”
Resumen
You do not have to accept Sprintax’s calculation or pay another service just to prepare a correction. The honest limit is that nobody can calculate your exact refund from the information in your question: the original and corrected numbers, earlier refund or credit, and tax year matter.
The right route depends first on whether the filed New York return is wrong and whether you were a full-year New York resident.
If your filed IT-201 needs correction and you were a full-year New York resident, complete the amendment for **that tax year** as a fully corrected return—not a list of differences. You can use New York’s [official 2025 fill-in form](https://www.tax.ny.gov/pdf/current_forms/it/it201x_fill_in_2d.pdf) and [instructions](https://www.tax.ny.gov/pdf/current_forms/it/it201xi.pdf); no second paid service is needed to use the paper route.
This is optional if you want help rebuilding the correct return. New York says you **should** use the software used for the original electronic return, but its [amended-return guidance](https://www.tax.ny.gov/pit/file/amended_return.htm) does not make another purchase a condition for correcting the return. Compare any proposed against the filed return, actual payments, and New York’s instructions before submitting.
If you mistakenly filed IT-201 but were a New York **nonresident or part-year resident**, New York specifically directs you to **IT-203-X**, not IT-201-X. Use the [2025 IT-203-X form](https://www.tax.ny.gov/pdf/2025/inc/it203x_2025_fill_in.pdf) and [instructions](https://www.tax.ny.gov/pdf/2025/inc/it203xi_2025.pdf) if 2025 was your tax year. [2025 IT-201 instructions](https://www.tax.ny.gov/pdf/current_forms/it/it201i.pdf)
Another service may help, but its number is not authoritative merely because different software produced it.

These steps establish the right form, rebuild the tax, and separate your new refund from money already paid back or credited.
Before calculating anything
Identify the tax year and get your filed return
Use your saved Sprintax filing to identify the tax year and whether you filed IT-201. If the copy is missing, request it with [Form DTF-505](https://www.tax.ny.gov/pdf/current_forms/misc/dtf505_fill_in.pdf) under [New York’s return-copy instructions](https://www.tax.ny.gov/help/contact/get-copy-of-return.htm). If the filed IT-201 was wrong because you were a New York nonresident or part-year resident, the correction is IT-203-X, not IT-201-X. The calculations in the next two steps use **2025** line numbers only.
Requisitos
If IT-201-X is the right form
Recalculate the entire corrected New York return
For 2025, fill out **all six pages** of the [official IT-201-X](https://www.tax.ny.gov/pdf/current_forms/it/it201x_fill_in_2d.pdf) using its [instructions](https://www.tax.ny.gov/pdf/current_forms/it/it201xi.pdf), the [2025 IT-201 instructions](https://www.tax.ny.gov/pdf/current_forms/it/it201i.pdf), and the [2025 tax tables](https://www.tax.ny.gov/pit/file/tax-tables/it201i-2025.htm). Enter what the *whole return should say*: correct income and New York adjustments, deductions, applicable state and city tax, credits, withholding, and payments. Do not enter only the difference from Sprintax’s first calculation. If your filed return is for another year, use [that year’s amended forms](https://www.tax.ny.gov/forms/income_amended_forms.htm) rather than transferring these 2025 line numbers.
Requisitos
2025 IT-201-X line numbers
Calculate the additional refund, not the total ever paid
Enter qualifying tax paid with or after the original return on **line 76**, and total the amendment’s payments on **line 77**. On **line 78**, enter the original IT-201 **line 77 total overpayment**, or New York’s adjusted overpayment; on **line 78a**, identify the portion of the original return’s overpayment applied to 2026 estimated tax. Compute **line 79 = line 77 − line 78**. If line 79 exceeds corrected **line 62 total tax**, **line 80 = line 79 − line 62** is the *additional* refund requested. Do not also subtract line 78a. If line 79 is smaller than line 62, the form instead calculates an amount owed on line 81. [Official 2025 form](https://www.tax.ny.gov/pdf/current_forms/it/it201x_fill_in_2d.pdf); [line instructions](https://www.tax.ny.gov/pdf/current_forms/it/it201xi.pdf)
Requisitos
Before the refund-claim deadline
Explain, sign, and file the corrected return
Explain the correction in the amendment’s explanation section and attach forms or schedules affected by it; **do not attach a duplicate of your original IT-201**. For a **2025 paper IT-201-X with no payment enclosed**, mail it to **STATE PROCESSING CENTER, PO BOX 61000, ALBANY NY 12261-0001**. If enclosing a check or money order, include **IT-201-V** and use **STATE PROCESSING CENTER, PO BOX 15555, ALBANY NY 12212-5555**. Generally, the refund amendment must be filed by the later of three years after the original filing or two years after paying the tax.
