## Major Compliance Updates You Should Know
### 1. IRS Modernized e-File Schema & Business Rules for 1040 (TY 2026)
Effective for tax year 2026 (returns filed in 2027), the IRS released **schema version 1.0** and updated business rules for the 1040 series. This affects digital formats, software vendors, and tax professionals. If your tax prep software or filing system isn’t updated to reflect these rules, returns may be rejected or delayed.

### 2. IRS Enrolled Agent Exam Fee Cuts
For the testing period May 2026–February 2027, **user fees per part of the Enrolled Agent Special Enrollment Examination (EA SEE)** have dropped from **$99 to $66**. A win for tax practitioners budgeting for their credentials. ([irs.gov](https://www.irs.gov/irb/2026-21_IRB?utm_source=openai))
### 3. Appearance of Final Regulations for Tip Deductions
Under the One, Big, Beautiful Bill Act, final regulations on “qualified tips” and eligible occupations are effective **June 12, 2026**. Workers and employers in tipped occupations should review the occupations list and understand when tips qualify under the new provisions.

## Penalties & Process Oversight: What You Should Track
- Deadlines for schema compliance and test filing windows for software developers under the IRS Modernized e-File program. Miss them once, you may endure costly remediations or delays later.
- For EA applicants: reduced fees do not change eligibility requirements—passing all three parts, good moral character, etc., still apply.
- Occupations not on the approved list for tip deductions may see their tip deductions disallowed; ensure your occupation is explicitly covered before claiming under section 224. ([irs.gov](https://www.irs.gov/pub/irs-irbs/irb26-18.pdf?utm_source=openai))
## Practical Compliance Tips
- **Audit your filing software** now to ensure the modernized schema (2026 v1.0) is supported. Confirm sample returns process correctly through e-file system.

- **Check if you’ll need an EA exam or work with EAs**: costs have gone down, possibly making it easier to engage. ([irs.gov](https://www.irs.gov/irb/2026-21_IRB?utm_source=openai))
- **Review payroll practices** if you employ tipped workers or handle tips. Update payroll software and documentation to align with the June 12 effective date. ([irs.gov](https://www.irs.gov/pub/irs-irbs/irb26-18.pdf?utm_source=openai))
## Consequences of Non-Compliance
- Penalties for filing incorrect or incomplete returns (e.g. tips misreported) or for missing filing schema updates can include fines, rejection of returns, and potential audits.
- For practitioners, missing updates in rules for EA exam scheduling or failing to follow the new test format could delay credentialing.
## Who Should Be Most Alert
- **Small business owners** with tipped staff (restaurants, bars, salons, etc.)
- **Software vendors** creating tax e-file tools
- **EA-aspiring professionals**
- **Payroll firms and accountants** updating processes to match regulatory changes
**Takeaway checklist**:
- Update or confirm software supports the 2026 1040 schema by its release.
- Adjust budgets or recertification plans now that EA exam fees are reduced.
- Review the final qualified tips regulations list before June 12 if you’re impacted.
Following these recent compliance changes carefully will limit your--and your clients’--exposure to unexpected taxes, delays, or penalties.
