Which 2018 home-improvement records may matter when you sell now
Guidance for Illinois sellers on evaluating 2018 home records, distinguishing between capital improvements and standard maintenance for tax preparation.
The short answer
When selling your Illinois home, reviewing records from 2018 is essential for establishing an accurate tax basis. Focus on identifying major capital improvements, such as structural additions or HVAC replacements, which increase your basis, compared to standard repairs which do not. Consult with a tax advisor to determine which documentation impacts your capital gain reporting.
Identifying Capital Improvements from 2018
For a 2018 improvement to qualify, it must have added value, prolonged the home's life, or adapted it to a new use. Examples include a new roof, upgraded electrical wiring, or a remodeled kitchen.
Verify these improvements against your 2018 financial statements. Ensure you have the original invoice and proof of payment, as estimates are not sufficient for IRS reporting.
Distinguishing Between Improvements and Repairs
A repair simply restores the property to its previous condition, such as patching drywall or painting. These costs are generally not added to your cost basis.
If your 2018 records contain mixed items, isolate the capital components. Ask a tax professional if a 2018 repair that was part of a larger renovation project can be aggregated as a capital improvement.
Legal Considerations for Disclosures
While reviewing 2018 records, note any material defects addressed during that time. If you completed a major renovation that corrected a known issue, ensure that this information is documented for your disclosure report.
Disclosures are not warranties, but reporting your 2018 repair history helps build a clear record of the property's condition for prospective buyers.
Decision Worksheet: 2018 Records Audit
Audit your 2018 files with this plan: 1) Separate all invoices from 2018. 2) Highlight receipts for projects costing over $1,000. 3) List each project and state its function (e.g., replacement vs. repair). 4) Note if a permit was pulled for the project. 5) Schedule a tax consultation to review if these specific items qualify as capital improvements.
Checklist
- Gather all invoices and receipts from home improvement projects in 2018.
- Sort documents into capital improvements and routine maintenance.
- Verify that your records show proof of payment.
- Cross-reference 2018 projects with your current disclosure report.
- Consult a tax advisor to confirm the impact of 2018 records on your basis.
Common questions
Can I count a 2018 roof replacement as an improvement?
Generally, replacing a roof is considered a capital improvement because it prolongs the life of the home. Keep the invoice and final payment record to document this.
What if I lost the 2018 receipts for my kitchen renovation?
Without clear documentation such as receipts or canceled checks, it may be difficult to substantiate the addition of these costs to your basis. Ask a tax professional if alternative evidence, such as bank statements or contractor records, is acceptable.
