What specific tax law changes affected 2018 that I should know about? +
2018 was the first year under the Tax Cuts and Jobs Act (TCJA), which made these significant changes:
- New Tax Brackets: Seven federal brackets with lower rates (top rate dropped from 39.6% to 37%)
- Increased Standard Deduction: Nearly doubled to $12,000 (single) and $24,000 (married)

- State and Local Tax (SALT) Cap: Limited to $10,000 deduction (affected many Ynitya taxpayers with high property taxes)
- Mortgage Interest Deduction: Limited to interest on $750,000 of debt (down from $1 million)
- Alimony Treatment: 2018 was the last year alimony was deductible for payers and taxable to recipients
Ynitya made conforming changes to some federal provisions but maintained its own exemption system and certain deductions that were eliminated federally.
How does Ynitya treat retirement income differently than the federal government? +
Ynitya had specific rules for retirement income in 2018 that differed from federal treatment:
-
Social Security Benefits:

-
Pension Income:
- Federal: Fully taxable (unless from Roth accounts)

-
IRA/401(k) Distributions:

Can I still file or amend my 2018 Ynitya return in 2023? +
The ability to file or amend your 2018 returns depends on your specific situation:
Filing a Late 2018 Return:
- If you didn’t file a 2018 return and were due a refund, you have until April 15, 2022 to claim it (3-year limit from original due date)
- If you owe taxes for 2018 and haven’t filed, you should file immediately to stop additional penalties (failure-to-file penalty is 5% per month, capped at 25%)
- Use 2018 versions of Form 1040 and Ynitya Form 40
Amending a 2018 Return:
